Ambitious Danish island ends fossil fuel use

A small Danish island ends fossil fuel use by combining ambitious aims with ensuring that local people have a say in cleaner replacements.

LONDON, 11 February, 2019 Tackling climate change is urgent. It’s too urgent to be feasible, say some critics. But as one Danish island ends fossil fuel use, its story shows it  may be time to think again.

In five years, by 2023, the UK Met Office says, global warming could temporarily rise by more than 1.5°C above pre-industrial levels, the target agreed by 195 governments in 2015. So the world needs to switch fast from fossil fuels to renewable energy.

The island of Samsø, off Denmark’s east coast, has wasted no time. Between 1998 and 2007 it abandoned its total dependence on imported fossil fuels and now relies entirely on renewables, mainly wind and biomass. It’s been singled out as the world’s first 100% renewable island by the Rapid Transition Alliance (RTA), which says Samsø can teach the world some vital lessons about changing fast and radically.

In 1997 Samsø, with 4,000 inhabitants, entered a Danish government competition to develop a model renewable energy community, aiming to prove that the country’s target of reducing carbon emissions by 21% was achievable.

Samsø’s winning proposal was based on strong community engagement and a cooperative ownership strategy. It showed how to make renewables a social, economic and energy success.

“Policy-making is too often limited to what is do-able in the short-term; establishing an ambitious mission can help reframe a problem, making the impossible possible”

With wind power now projected to be Europe’s biggest energy source by 2027, the RTA says, one essential element in making it work successfully is how it is managed − and Samsø is a trailblazer.

What the islanders did was straightforward enough. By the year 2000 they had installed 11 wind turbines, covering their electricity needs. A further 10 offshore turbines were erected in 2002, generating enough energy to offset emissions from their cars, buses, tractors and the ferry to the mainland. Three-quarters of their heating and hot water now comes from biomass boilers fuelled with locally grown straw.

Samsø’s transition, the Alliance says, proved that a wholesale shift to renewable energy was possible with existing technology and limited government assistance.

Nowadays, residents are producing so much more clean energy than they need (and exporting what they don’t use) that, in effect, they have an average annual CO2 footprint of minus 12 tonnes per person, helping their fellow citizens to lower their emissions too (the average Dane emits 6.2 tonnes of CO2 a year, the average Briton 10 tonnes).

Active buy-in

Samsø, the argument runs, proves the effectiveness of setting ambitious targets – and meeting them. The Alliance says Samsø’s transition is impressive because it was achieved with the active buy-in (both figuratively and financially) of the local community.

Winning hearts and minds was crucial. People often oppose on-shore wind turbines as a visual intrusion, a blot on the landscape. So the transition organisers, Samsø Energy Academy, worked out how to include the islanders as the turbines’ owners.

They had a simple principle: if you could see a turbine from your window, you could sign on as a co-investor, meaning that anyone living with the technology had a stake in it and stood to.benefit

With so many islanders having a direct stake in the turbines there is now near unanimity that the renewable transition has been good for Samsø. Of the 11 onshore turbines, nine are owned privately by local farmers and two by local cooperatives. Five of the offshore turbines are owned by the municipality, three privately and two cooperatively by small shareholders.

Sceptical island

Before the transition began Samsø had relied mainly on oil, with its electricity generated in coal-fired power plants on the mainland. The potential for renewables had not been explored, and there was deep scepticism towards them. A lack of opportunities for education and work had led many young people to leave the island.

The islanders embraced the transition, but not because of climate change. Instead, most looked to its potential to provide jobs, strengthen the local economy and secure greater energy independence.

Key to Samsø’s success, the Alliance believes, was the insistence on transparency, consultation, and starting from what people wanted. From the start there was full disclosure of information, with the master plan published in the island’s library and information shared through the local newspaper and discussed in detail at regular community meetings.

Samsø’s long tradition of agricultural cooperatives also helped to ensure strong local engagement. There was ample time for discussion and decision-making, which helped to build confidence and a strong sense of collective ownership of decisions.

Listening to doubters

Sometimes the organisers’ focus on flexibility and committment to meeting local expectations came at a price. One site planned for an onshore turbine, for example, aroused concerns from birdwatchers, church members and holiday home owners.

So the plans were changed, even though this meant choosing another site where turbine installation was more difficult and less energy could be generated.

The Alliance says: “This meant that the community felt genuine ownership over the siting of the wind turbines, which helped to dispel any negative feelings around them.”

It draws another lesson from Samsø, too. The transition to 100% renewables was achieved, the RTA believes, because the Danish government had an ambitious mission, which everyone wanted to realise:

Energy from greenhouse gases is possible

Laboratories can make energy from greenhouse gases, power smartphones with their own radiation, and cut shipping costs naturally. And each could become reality.

LONDON, 8 February, 2019 – Researchers have found ways to realise a modern version of the medieval alchemists’ dream  not turning base metals into gold, but conjuring energy from greenhouse gases, exploiting abundant pollutants to help to power the world.

Korean scientists have developed a sophisticated fuel cell that consumes carbon dioxide and produces electricity and hydrogen – potentially another fuel – at the same time.

Researchers based in the US and Spain have devised a nanoscale fabric that converts electromagnetic waves into electrical current.

The dream is that a smartphone coated with the fabric could, without benefit of a battery, charge itself from the ambient wi-fi radiation that it exploits for texts, calls and data.

German scientists have taken a leaf from nature’s book and applied it – so far in theory – to bulk cargo shipping. Salvinia molesta, a floating fern native to Brazil, isolates itself from water with a thin sheath of air. If the large carriers could adopt the Salvinia trick and incorporate a similar layer of air in the anti-fouling coating on the hull, this would reduce drag sufficiently to save 20% of fuel costs.

To the Urals

And in yet another demonstration of the ingenuity and innovative ambition on show in the world’s laboratories, another German team has looked at the large-scale climate economics of artificial photosynthesis – a system of semiconductors and oxides – that could draw down carbon dioxide from the atmosphere and deliver stable chemical compounds.

To take 10 billion metric tons of carbon dioxide out of the atmosphere each year would demand a forest that covered all Europe as far as the Urals. But to do the same job, a commercial forest of “artificial leaves” would require a land area about the size of the German federal state of Brandenburg.

All these ideas are ready for further development. None is so far anywhere near the commercial market.

But all are evidence that chemists, engineers, physicists and biologists have taken up the great climate challenge: how to power modern society without fuelling even faster global warming and climate change that could, ultimately, bring global economic growth to a devastating halt.

And, as many researchers see it, that means not just by-passing the fossil fuels that drive climate change, but actively exploiting the ever-higher ratios of carbon dioxide now in the atmosphere, or soon to emerge from power station chimneys

“The best thing now would be to drastically reduce emissions immediately – that would be safer and much cheaper”

Scientists at UNIST, Korea’s National Institute of Science and Technology, report in the journal iScience that in collaboration with engineers at the Georgia Institute of Technology in the US they have already developed a hybrid sodium-carbon dioxide system of electrolytes that converts dissolved carbon dioxide to sodium bicarbonate and hydrogen, with a flow of electric current.

Efficiency is high – with 50% of the carbon dioxide exploited – and could be higher. And their test apparatus so far has run in stable fashion for 1000 hours. The system uses a new approach to materials to exploit something in the air everywhere.

And that too is exactly what researchers in the US have done: they report in the journal Nature that they have fashioned a flexible sheet of ultra-thin material that serves as what they call a “rectenna”: a radio-frequency antenna that harvests radiation, including wi-fi signals, as alternating current waveforms, and feeds them to a nanoscale semiconductor that converts it to direct current.

So far, the rectenna devices have produced 40 microwatts of power: enough to fire up a light-emitting diode, or power a silicon chip.

“We have come up with a new way to power the electronics systems of the future – by harvesting wi-fi energy in a way that’s easily integrated in large areas – to bring intelligence to every object around us,” said Tomás Palacios, an electrical engineer at Massachusetts Institute of Technology, and one of the authors.

Magic carpet

The waterweed Salvinia molesta exploits bubbles to keep itself afloat but out of the water: it literally rides in the water on a little magic carpet of air. The hydrophobic plant is regarded as an invasive pest, but the way it harnesses air to keep itself afloat and on top of things provides a lesson not just for evolutionary biologists but for engineers.

Researchers from the University of Bonn have been looking at the problem of the global shipping fleet: cargo freighters burn 250 million tonnes of fuel a year and emit a billion tonnes of carbon dioxide, much of it because of the sheer drag of moving a hull through the waves. So anything that reduces drag saves fuel (which accounts for half of all transport costs).

The German scientists report in the Philosophical Transactions A of the Royal Society that their experiments with hull coatings based on the lessons of Salvinia could in the medium term cut fuel costs by up to 20% and on a global scale reduce emissions by 130 million tonnes a year. If the same coating discouraged barnacles as well, the saving could reach 300 million tonnes – 1% of global CO2 output.

To keep global warming to the promised level of no more than 1.5°C, an ambition signed up to by 195 nations in Paris in 2015, global fossil fuel emissions will have to reach zero by 2050.

Right now, nations are adding 42 billion tonnes of carbon dioxide to the atmosphere every year. So there is pressure to find ways to remove carbon from the atmosphere and store it.

Huge economy

German scientists report in the journal Earth System Dynamics that they did the sums and calculated that to take 10 billion tonnes of carbon dioxide out of the atmosphere using the machinery supplied by 3 billion years of evolution would require new forest plantations that stretched over 10 million kilometres. This is about the size of continental Europe.

But supposing artificial leaf systems developed in laboratories could be further developed on a massive scale? These leaves would draw down carbon dioxide and deliver it for permanent storage or for chemical conversion to plastic or building material.

If so, then efficient synthetic photosynthesis installations could do the same job from an area of only 30,000 square kilometres.

“These kinds of modules could be placed in non-agricultural regions – in deserts, for example. In contrast to plants, they require hardly any water to operate,” said Matthias May of the Helmholtz-Zentrum Berlin, one of the authors. It would of course come at a formidable cost – about €650 bn
or US$740 bn a year.

Pyrenees pipeline veto is setback for gas

The global gas industry’s prospects will suffer from the Pyrenees pipeline veto imposed by regulators, say opponents of fossil fuels.

LONDON, 30 January, 2019 − The Pyrenees pipeline veto announced by regulators in France and Spain, rejecting plans to complete a €3 billion (£2.6 bn) gas link between both countries, is being hailed as a major victory by climate change protestors.

The pipeline, which would have doubled the capacity for transporting natural gas through the mountains on the Franco-Spanish border, was supported by the European Union as a way to reduce its reliance on Russian gas, but the project now appears doomed.

Campaigners in both countries said it was a defeat for the fossil fuel industry and a major step in preventing the EU from continuing to rely on gas instead of renewables.

“MidCat”, as the proposed Midi-Catalunya pipeline was known, would have allowed the flow of gas in both directions across the Pyrenees. Significantly, it would have allowed liquefied gas from terminals in Spain to be pumped north to France to replace an estimated 10% of the gas coming south from Russia.

Energy corporations Enagás and Teréga have been promoting its construction since 2005, and in 2013 the European Commission added the project to its list of favoured “Projects of Common Interest”.

“The gas industry should realise that the party is over and that we can’t keep sinking taxpayer billions into more fossil fuels”

The companies presented the pipeline as a necessary piece of infrastructure to improve Europe’s energy security and to fight against climate change, but protestors said the money should instead have been invested in renewables.

Although it was only one of 90 projects designed to improve the transport of gas in the EU, it was one of the largest. Gas companies have lobbied hard everywhere in Europe to get the Commission and politicians to see gas as an interim step between coal and renewables, but campaigners say the climate cannot afford to burn gas either.

Clemence Dubois, a campaigner at 350.org, said: “All across Europe, we are building a future free of fossil fuels. Together we are making it harder and harder for dirty energy companies to build their pipelines and impose a destructive and outdated model of business.

“We have won an important victory because we have prevented the construction of a major piece of infrastructure that is totally incompatible with a liveable climate.”

Last week the French Energy Regulatory Commission (CRE) and the Spanish National Commission on Markets and Competition  (CNMC) issued a joint statement rejecting the scheme, not on climate grounds but because they said it was too costly and they could not see a sufficient need for it.

Red card

Antoine Simon, fossil free campaigner for Friends of the Earth Europe, said: “This dramatic red card to the MidCat gas pipeline marks a major victory in the fight to stop a new climate-wrecking fossil gas project. Activists, NGOs and local communities have been fighting this useless project for years, knowing it’s bad for taxpayers, consumers, local people, and the climate – and today they’ve been proved right.

“This is a major setback for the gas industry, and calls into question the hundred other gas projects that the EU has prioritised for support, all of which are similarly unviable. Gas is a dangerous fossil fuel which is killing the climate.

“The gas industry should realise that the party is over and that we can’t keep sinking taxpayer billions into more fossil fuels.”

Although there has been fierce opposition from environment groups in the region, the pipeline’s future was in doubt from the moment the Spanish Conservative government lost power in June last year and socialists took over the environment ministry.

When last November Spain pledged to switch to 100% renewable electricity by 2050 and to become carbon-neutral soon afterwards, it was clear that the new pipeline was unlikely to find favour. − Climate News Network

Junk fossil fuel plants and stay below 1.5°C

The world could yet contain global warming to 1.5°C – but only if governments act now to junk fossil fuel plants and ditch all those smoking power stations.

LONDON, 24 January, 2019 British scientists have worked out how to make sure of a better-than-even chance that 195 nations can fulfill a promise made in Paris in 2015 to stop global warming at 1.5°C by the end of the century: junk fossil fuel plants.

The answer is simple: phase out fossil fuel hardware as soon as it reaches the end of its effective life. Scrap the old petrol-powered car and buy electric. Shut down the coal-burning power generator and get electricity from the wind or the sunlight. Find some renewable fuel for jet planes. Deliver transoceanic cargoes with a marine fuel that isn’t derived from oil or coal.

There is a catch. Those 195 nations should have already started doing all these things by the end of 2018. To delay a start until 2030 could mean failure, even if – little more than a decade from now – the world then accelerated its escape from fossil fuel addiction.

“Although the challenges laid out by the Paris Agreement are daunting, we indicate 1.5°C remains possible and is attainable with ambitious and immediate emission reduction across all sectors”, the researchers say in the journal Nature Communications.

Long working life

Their study is based on the match of climate models and a range of possible scenarios and is focused on energy generation, transport and industry: these account for 85% of the carbon dioxide emissions that have begun to warm the planet and change the climate, and for which researchers have the most reliable lifetime data.

“All fossil fuel infrastructure, such as coal power plants, carries a climate change commitment. A new coal plant will emit carbon dioxide for roughly 40 years across its lifecycle which in turn affects global warming,” said Christopher Smith, of the University of Leeds, who worked with colleagues from Britain, Norway, Austria, Switzerland and Canada to model a huge range of possibilities to identify a timetable strategy with a probability of success of 64%.

“Investments into carbon-intensive infrastructure and their development and maintenance lock us in to the associated carbon emissions and make the transition to lower-carbon alternatives more difficult.

“Our research found that the current amount of fossil fuel infrastructure in the global economy does not yet commit us to exceeding the 1.5°C temperature rise limit put forward by the Paris Agreement.

“Climate change policy does need some good news, and [the] message is that we are not (quite) doomed yet”

“We may have missed starting the phase-out by the end of 2018, but we are still within the margin of achieving the scenario the model put forward.”

The implication is that no new oil wells should be drilled, or mines opened; no more coal-burning or oil-burning power plant commissioned. Infrastructure in use now will be retired when it reaches the end of its life, perhaps 40 years from now.

The scientists don’t discuss how feasible – in political, economic and development terms – such a step will be. Their point is that, to keep the Paris promise, the world must start now.

And their assumption does not incorporate any of the much-feared and potentially catastrophic changes in the near future, as ice caps melt and permafrost thaws to release vast quantities of carbon trapped in once-frozen Arctic soils, and make global warming accelerate.

Series of warnings

The study is not the first to warn that the time available for ending fossil fuel dependence and switching to renewable energy resources is limited. Almost as soon as the world made its historic agreement in Paris many scientists warned that on the basis of pledges made at the time the target would be difficult or impossible to achieve.

The planet has already warmed by 1°C since the Industrial Revolution began to release ever greater levels of greenhouse gases into the atmosphere. One study forecast that a world already at least 1.5°C warmer than it had been for most of human history could arrive by 2026.

Other scientists have welcomed the Leeds research. “Climate change policy does need some good news, and their message is that we are not (quite) doomed yet,” said Phillip Williamson of the University of East Anglia.

“If from now on the greenhouse gas-emitting power plants, factories, cars, ships and planes are replaced by non-polluting alternatives as they reach the end of their lifetimes, then the threshold of 1.5°C warming might not be crossed. Yet that is a very big ‘if’.” – Climate News Network

The world could yet contain global warming to 1.5°C – but only if governments act now to junk fossil fuel plants and ditch all those smoking power stations.

LONDON, 24 January, 2019 British scientists have worked out how to make sure of a better-than-even chance that 195 nations can fulfill a promise made in Paris in 2015 to stop global warming at 1.5°C by the end of the century: junk fossil fuel plants.

The answer is simple: phase out fossil fuel hardware as soon as it reaches the end of its effective life. Scrap the old petrol-powered car and buy electric. Shut down the coal-burning power generator and get electricity from the wind or the sunlight. Find some renewable fuel for jet planes. Deliver transoceanic cargoes with a marine fuel that isn’t derived from oil or coal.

There is a catch. Those 195 nations should have already started doing all these things by the end of 2018. To delay a start until 2030 could mean failure, even if – little more than a decade from now – the world then accelerated its escape from fossil fuel addiction.

“Although the challenges laid out by the Paris Agreement are daunting, we indicate 1.5°C remains possible and is attainable with ambitious and immediate emission reduction across all sectors”, the researchers say in the journal Nature Communications.

Long working life

Their study is based on the match of climate models and a range of possible scenarios and is focused on energy generation, transport and industry: these account for 85% of the carbon dioxide emissions that have begun to warm the planet and change the climate, and for which researchers have the most reliable lifetime data.

“All fossil fuel infrastructure, such as coal power plants, carries a climate change commitment. A new coal plant will emit carbon dioxide for roughly 40 years across its lifecycle which in turn affects global warming,” said Christopher Smith, of the University of Leeds, who worked with colleagues from Britain, Norway, Austria, Switzerland and Canada to model a huge range of possibilities to identify a timetable strategy with a probability of success of 64%.

“Investments into carbon-intensive infrastructure and their development and maintenance lock us in to the associated carbon emissions and make the transition to lower-carbon alternatives more difficult.

“Our research found that the current amount of fossil fuel infrastructure in the global economy does not yet commit us to exceeding the 1.5°C temperature rise limit put forward by the Paris Agreement.

“Climate change policy does need some good news, and [the] message is that we are not (quite) doomed yet”

“We may have missed starting the phase-out by the end of 2018, but we are still within the margin of achieving the scenario the model put forward.”

The implication is that no new oil wells should be drilled, or mines opened; no more coal-burning or oil-burning power plant commissioned. Infrastructure in use now will be retired when it reaches the end of its life, perhaps 40 years from now.

The scientists don’t discuss how feasible – in political, economic and development terms – such a step will be. Their point is that, to keep the Paris promise, the world must start now.

Nuclear sunset overtakes fading dreams

As atomic energy gets ever more difficult to afford and renewables become steadily cheaper, a nuclear sunset awaits plans for new plants.

LONDON, 21 January, 2019 − Once hailed as a key part of the energy future of the United Kingdom and several other countries, the high-tech atomic industry is now heading in the opposite direction, towards nuclear sunset.

It took another body blow last week when plans to build four new reactors on two sites in the UK were abandoned as too costly by the Japanese company Hitachi. This was even though it had already sunk £2.14 billion (300 bn yen) in the scheme.

Following the decision in November by another Japanese giant, Toshiba, to abandon an equally ambitious scheme to build three reactors at Moorside in the north-west of England, the future of the industry in the UK looks bleak.

The latest withdrawal means the end of the Japanese dream of keeping its nuclear industry alive by exporting its technology overseas. With the domestic market killed by the Fukushima disaster in 2011, overseas sales were to have been its salvation.

UK policy needed

It also leaves the British plan to lead an international nuclear renaissance by building ten new nuclear stations in the UK in tatters, with the government facing an urgent need for a new energy policy.

Across the world the nuclear industry is faring badly, with costs continuing to rise while the main competitors, renewables, both wind and solar, fall in price. The cost of new nuclear is now roughly three times that of both wind and solar, and even existing nuclear stations are struggling to compete.

Plans by another Japanese giant, Mitsubishi Heavy Industries, to build four reactors at Sinop on the Black Sea coast of Turkey in partnership with the French were also abandoned in December because of ever-escalating costs.

These reverses mean that the main players left in the business of building large reactors are state-owned – EDF in France, Kepco in South Korea, Rosatom in Russia, and a number of Chinese companies. No private company is now apparently large enough to bear the costs and risk of building nuclear power stations.

Sole survivor

In the UK only one of the original 10 planned nuclear stations is currently under construction. This is the twin reactor plant at Hinkley Point in Somerset in the West of England being built by EDF, a construction project twice as big as the Channel Tunnel, and at a cost of £20 bn (US$25.7 bn).

Already, almost before the first concrete was poured, and with 3,000 people working on the project, it is two years behind schedule and its completion date has been put back to 2027.

The problem for EDF and Kepco is that both France and South Korea have gone cool on nuclear power, both governments realising that renewables are a cheaper and better option to reduce carbon emissions.

“The cost of new nuclear is now roughly three times that of both wind and solar, and even existing nuclear stations are struggling to compete”

To keep expanding, both companies need to export their technology, which means finding other governments prepared to subsidise them, a tall order when the price is so high.

EDF’s current export markets are China and the UK. In England, in addition to Hinkley Point, EDF plans another two reactors on the east coast. How the heavily-indebted company will finance this is still to be negotiated with the UK government. China has bought two French reactors, but there are no signs of new orders.

Kepco is building four reactors in the United Arab Emirates,  a contract obtained in 2009 and worth $20 bn, but it has obtained no orders since.

That leaves Russia and China as the main players. Since nuclear exports for both countries are more a means of exerting political influence than making any financial gain, the cost is of secondary importance and both countries are prepared to offer soft loans to anyone who wants one of their nuclear power stations.

Growth points

On this basis Russia is currently building two reactors in Bangladesh and has a number of agreements with other countries to export stations. Last year construction started on a Russian reactor in Turkey.

China has been the main engine for growth in the nuclear industry, partly to feed the country’s ever-growing need for more electricity. In 2018 only two countries started new reactors – eight were in China and two in Russia.

Significantly, while China has accounted for 35 of the 59 units started up in the world in the last decade and has another dozen reactors under construction, the country has not opened any new construction site for a reactor since December 2016.

By contrast, in both 2017 and 2018 the Chinese have dramatically increased installation of both solar and wind farms, obviously a much quicker route to reducing the country’s damaging air pollution.

Maintenance problems

While there are 417 nuclear reactors still operating across the world and still a significant contributor to electricity production in some countries, many of them are now well past their original design life and increasingly difficult to maintain to modern safety standards.

There is little sign of political will outside China and Russia to replace them with new ones.

Even in the UK, with a government that has encouraged nuclear power, there is increasing resistance from consumers to new nuclear plants, as they will be asked to pay dearly through their utility bills for the privilege.

Despite the fact that the UK nuclear lobby is strong, its influence may wane when consumers realise that the country has ample opportunities to deploy off-shore and on-shore wind turbines, solar and tidal power at much lower cost. − Climate News Network

Battery boom aids climate change battle

The fastest-expanding industrial sector on the planet is now electricity storage − a battery boom which heralds an end to the need for fossil fuels.

LONDON, 18 January, 2019 − Billions of dollars are being invested worldwide in the developing battery boom, involving research into storage techniques to use the growing surpluses of cheap renewable energy now becoming available.

Recent developments in batteries are set to sweep aside the old arguments about renewables being intermittent, dismissing any need to continue building nuclear power plants and burning fossil fuels to act as a back-up when the wind does not blow, or the sun does not shine.

Batteries as large as the average family house and controlled by digital technology are being positioned across electricity networks. They are being charged when electricity is in surplus and therefore cheap, and the power they store is resold to the grid at a higher price during peak periods.

According to Bloomberg, around US$600 billion will be invested in large-scale batteries over the next 20 years to provide back-up to the grid and power for the expected boom in electric cars.

The cost of batteries is also expected to fall by 50% in the next decade, following the same pattern as the drop in cost of solar panels.

“The generally-held belief that there was no way to store electricity has been disproved. The battery boom means it is now just a question of finding the easiest and most economic way of doing it”

It is already financially viable for individual businesses to install batteries to buy electricity when it is cheap, so as to use it during peak periods. Two recent examples are the English premier league club Arsenal FC and a hotel in Edinburgh, the Scottish capital.

For Arsenal it makes sense to have a giant battery under its London stadium to store cheap power for use when its floodlights are needed during matches which are usually played when electricity prices are at their peak.

In Edinburgh, where there is often a surplus of wind power at night, the batteries provide cheap power for the 200-bedroom Premier Inn hotel in the morning and evening rush. In both cases the capital cost of the batteries is soon repaid in lower power costs.

Currently most large batteries are made of lithium, a relatively scarce and expensive mineral. Large investments are being made to find a way of making lithium batteries cheaper and more efficient, and the search is on for less expensive materials that can also be used to store electricity in battery form.

In Belgium, ironically on the site of a former coalmine, five large experimental batteries have been installed near Brussels to test the best technologies.

New possibilities

One of the latest advances is to use another rare metal, vanadium. Vanadium flow batteries are large static batteries that last for decades and can be charged and discharged completely thousands of times. They are not portable, but last for years without deterioration and are increasingly being deployed by national grids to boost supply during peak demand. A Canadian company, CellCube, has just sold a large battery plant to France.

This has been hailed as one of the most promising technologies in energy storage, but there are many other possibilities under development including high-energy magnesium batteries and lithium-air batteries, which are an advance on the current lithium-ion versions used in electric cars and for grid storage.

There are also new types of chemical batteries under trial as large-scale static installations which allow the grid to pump out more power at peak times.

The key battle for all these technologies is beating rivals on price. This means not just other battery types, but other options under development for storing energy. Surplus energy from renewables is also being used to produce hydrogen, while the surplus from solar power is often stored as heat.

In the first few years of this century the generally-held belief that there was no way to store electricity has been disproved. The battery boom means it is now just a question of finding the easiest and most economic way of doing it, and in doing so making a giant step towards a carbon-free future. − Climate News Network

Swedes top climate change resisters’ league

Some governments take global warming seriously, while others defy the science and virtually ignore it. The climate change resisters’ league names names.

LONDON, 8 January, 2019 – There are countries that are in earnest about the way humans are overheating the planet, the climate change resisters; and there are others that give what is one of the most fundamental problems facing the world only scant attention.

Annually over the past 14 years a group of 350 energy and climate experts from around the globe has drawn up a table reflecting the performance of more than 70 countries in tackling climate change.

Together this group of nations is responsible for more than 90% of total climate-changing greenhouse gas emissions (GHG).

In the just published index looking at developments in 2018, Sweden, Morocco and Lithuania are the top performers in combatting global warming. At the other end of the scale are Iran, the US and – worst performer by a significant margin – Saudi Arabia.

The analysis – called the Climate Change Performance Index, or CCPI – is published by German Watch and the New Climate Institute, both based in Germany, plus the Climate Action Network, which has its headquarters in Lebanon.

“No country has yet done enough in terms of consistent performance across all the indicators required to limit global warming to well below 2°C”

The CCPI compares the various countries’ performances across three categories – GHG emissions, renewable energy, and energy use. The index also evaluates the progress made by nations in implementing the landmark 2015 Paris Agreement on climate change.

Morocco comes in for particular praise in the index. “With the connection of the world’s largest solar plant and multiple new wind farms to the grid, the country is well on track for achieving its target of 42% installed renewable energy capacity by 2020 and 52% by 2030.”

India has risen up the performance league and is praised for its moves into renewable energy, though concerns are expressed about the country’s plans to build new coal-fired power plants. Coal is the most polluting fossil fuel.

The UK and the EU as a whole score reasonably highly in the index, but the CCPI compilers issue several caveats and leave the top three places in the league table blank.

Poor Saudi record

“This is because no country has yet done enough in terms of consistent performance across all the indicators required to limit global warming to well below 2°C, as agreed in the Paris Agreement,” they say.

Russia, Canada, Australia and South Korea all score badly in the CCPI, with the US just one place off the bottom spot.

“The refusal of President Trump to acknowledge climate change being human-caused, and his dismantling of regulations designed to reduce carbon emissions, result in the US being rated very low for its national and international climate policy performance.”

Saudi Arabia, the world’s biggest oil exporter, has over the years repeatedly come bottom of the CCPI.

“The country continues to be a very low performer in all index categories and on every indicator on emissions, energy use and renewable energy.”

Mid-East’s heightened risk

The Saudis are also strongly criticised for their obstructionist tactics at climate negotiations.

At a recent international meeting on climate change held in Katowice in Poland, Saudi Arabia – together with the US, Russia and Kuwait – was accused of holding up proceedings and of refusing to acknowledge the vital importance of taking action on global warming.

The Middle East, and North Africa and the Gulf region in particular, are considered by scientists to be among the areas which are likely to feel the most serious impacts of climate change in the near future.

Already the region is being hit by ever-rising temperatures; climate researchers say that before too long it’s likely that people working outside in the intense summer heat in population centres such as Dubai, Abu Dhabi and Doha – including those repairing air conditioning and water systems, or overseeing emergency services – could be putting their lives at risk. – Climate News Network

VW says climate drives its electric spurt

Reputation and public confidence in your products are vital for global corporations, especially for one of the world’s biggest carmakers – hence VW’s electric spurt.

LONDON, 10 December, 2018 – As part of what it says is its commitment to tackling climate change, VW, the German auto giant, is embarking on an electric spurt, pressing ahead with plans aimed at producing more than a million electric cars a year by 2025.

In the vanguard of VW’s push into electric vehicles is the company’s plant at Zwickau, in the east of Germany, where an entire factory that once produced petrol and diesel car models is being converted to solely manufacturing electrically powered vehicles.

VW says that by the end of 2019 mass production of the ID, its new electric model, will begin at Zwickau; the aim is to eventually manufacture up to 330,000 electric models a year at the plant.

“With our electric cars we want to make a substantial contribution to climate protection”, says Thomas Ulbrich, head of the company’s electric car division.

“The global automotive industry is experiencing a process of fundamental structural change.

Affordable and popular

“Efficient, modern production facilities will be the key. In one year, this plant will become the starting point for our global electric offensive.”

Ulbrich says the aim is to take electric cars out of their niche and produce cars that will be affordable to millions – similar to the way the VW Beetle became popular around the globe.

VW says it’s investing about €1.2 billion in altering production facilities at Zwickau, where more than 7,500 people are employed. The company is also creating electric car plants elsewhere, including two in China – one near Shanghai and the other at Foshan in the south of the country.

Several other major car manufacturers have announced similar plans to ramp up electric vehicle production.

VW, by some measures the world’s biggest carmaker, has been struggling to repair its image after the company was forced in 2015 to admit it had sold nearly 600,000 cars in the US which had been fitted with special devices designed to circumvent emissions regulations and falsify exhaust gas tests.

“In one year, this plant will become the starting point for our global electric offensive”

The gases – nitric oxide and nitrogen dioxide – not only contribute to global warming but create pollution as well and can lead to health problems.

VW admitted that its engineers had designed a software system for its cars sold in the US which switched emissions controls on when vehicles were being tested and off during normal driving.

A number of other car producers, including the Japanese/French conglomerate Mitsubishi, have admitted falsifying various data relating to vehicle performance.

In the latest twist in the VW scandal, US prosecutors have alleged that what they describe as an “appalling fraud” was authorised by those at the very top of the company, with a former CEO involved.

To date, it’s estimated VW has paid out approximately US$25 bn in damages in relation to the emissions case. Court actions are ongoing with investors in VW who claim to have lost money over the scandal also suing the company. – Climate News Network

“With our electric cars we want to make a substantial contribution to climate protection”, says Thomas Ulbrich, head of the company’s electric car division.

“The global automotive industry is experiencing a process of fundamental structural change.

Affordable and popular

“Efficient, modern production facilities will be the key. In one year, this plant will become the starting point for our global electric offensive.”

Ulbrich says the aim is to take electric cars out of their niche and produce cars that will be affordable to millions – similar to the way the VW Beetle became popular around the globe.

VW says it’s investing about €1.2 billion in altering production facilities at Zwickau, where more than 7,500 people are employed. The company is also creating electric car plants elsewhere, including two in China – one near Shanghai and the other at Foshan in the south of the country.

Several other major car manufacturers have announced similar plans to ramp up electric vehicle production.

VW, by some measures the world’s biggest carmaker, has been struggling to repair its image after the company was forced in 2015 to admit it had sold nearly 600,000 cars in the US which had been fitted with special devices designed to circumvent emissions regulations and falsify exhaust gas tests.

“In one year, this plant will become the starting point for our global electric offensive”

The gases – nitric oxide and nitrogen dioxide – not only contribute to global warming but create pollution as well and can lead to health problems.

VW admitted that its engineers had designed a software system for its cars sold in the US which switched emissions controls on when vehicles were being tested and off during normal driving.

A number of other car producers, including the Japanese/French conglomerate Mitsubishi, have admitted falsifying various data relating to vehicle performance.

In the latest twist in the VW scandal, US prosecutors have alleged that what they describe as an “appalling fraud” was authorised by those at the very top of the company, with a former CEO involved.

To date, it’s estimated VW has paid out approximately US$25 bn in damages in relation to the emissions case. Court actions are ongoing with investors in VW who claim to have lost money over the scandal also suing the company. – Climate News Network

2018 will show record carbon emissions

Record carbon emissions are set to mark 2018. And although investment in renewable energy is rising, the world is still warming dangerously fast.

LONDON, 6 December, 2018 – For the second year running, the world will have a doubtful achievement to claim by 31 December: record carbon emissions.

Even before the close of 2018, scientists behind the biggest accounting effort on the planet, the Global Carbon Budget, warn that emissions from coal, oil and gas will have dumped a record 37 billion tonnes of carbon dioxide equivalent (a way of  comparing the emissions from various greenhouse gases based on their global warming potential) into the atmosphere by the end of this month.

This is 2.7% more than last year, which also showed an increase. Human destruction of the world’s forests will add another four billion tonnes in the same 12 months.

The news comes as 190 nations negotiate in Katowice in Poland to work out how to meet the targets they set in 2015 in Paris,  to contain global warming to no more than 2°C by 2100, and if possible no more than 1.5°C.

Little time left

But in a commentary in Nature a second set of scientists warns that time is running out. At the present rate of fossil fuel use, the world is set to breach the 1.5°C target by 2030, rather than the 2040 everybody had assumed.

That is because rising emissions, declining air pollution and natural climate cycles working together will make climate change more fast and furious than expected.

There are hopeful signs: renewable energy investment has begun to accelerate, and some nations have started to reduce fossil fuel emissions.

But the confirmation of yet another record year for fossil fuel combustion – after three consecutive years, 2014-16, in which fossil fuel use seemed to have peaked and might start to fall – suggests that even those nations most concerned about climate change are not doing enough.

“This cannot continue. It must not. To give us a chance of meeting the Paris climate goals, emissions need to fall, and fast”

The biggest emitters are China, the US, India, Russia, Japan, Germany, Saudi Arabia, South Korea and Canada, but taken as a collective, the European Union elbows India out of third place.

If the UK, a self-proclaimed climate progressive country, could celebrate the exploitation of a new North Sea oil field while at the same time exploring for shale gas and expanding its biggest airport, it should be no surprise that global emissions were rising, said Kevin Anderson, professor of energy and climate change at the Tyndall Centre at the University of Manchester, UK.

“If the climate-aware EU is planning new pan-Europe pipelines to lock in high carbon gas for decades to come, is it any surprise global emissions are rising? If ever-green Sweden, currently without any major gas infrastructure, is enthusiastically building a new gas terminal in Gothenburg – is it any surprise emissions are rising?”

Aimed at negotiators

Publication of the Global Carbon Project review for 2018 is timed to focus minds in Katowice, and as a reminder of how much has yet to be done to contain climate change.

“To limit global warming to the Paris Agreement goal of 1.5°C, CO2 emissions would need to decline by 50% by 2030 and reach zero around 2050,” said Corinne Le Quéré, who directs theTyndall Centre for climate change at the University of East Anglia, UK.

“We are a long way from this, and much more needs to be done because if countries stick to commitments they have already made, we are on track to see 3°C of global warming.

“This year we have seen how climate change can already amplify the impact of heatwaves worldwide. The California wildfires are just a snapshot of the growing impacts we face if we don’t drive emissions down rapidly.”

Renewable energy grows

Paradoxically, the data in the report published in one version in Environmental Research Letters and in more detail in the journal Earth System Science Data also point to an acceleration towards renewable sources of energy: the political shorthand for this process is “decarbonisation.”

Coal consumption in Canada and the US had dropped 40% since 2005. Christiana Figueres, who in 2015 as a UN climate chief presided over the wheeling and dealing that resulted in the Paris Agreement, argues in another commentary in Nature that there are signs of promise.

Thousands of businesses in 120 countries had signed up to the Paris goals, which could bring $26 trillion in economic benefits, including 65 million new jobs in what she called the “booming” low carbon economy. “We have already achieved things that seemed unimaginable just a decade ago,” she said.

Robust accounting

“Exponential progress in key solutions is happening and on track to displace fossil fuels. Renewable energy costs have dropped by 80% in a decade, and today, over half of all new energy generation capacity is renewable.

“Before 2015 many people thought the Paris Agreement was impossible, yet thousands of people and institutions made the shift from impossible to unstoppable.”

But, warned David Reay, professor of carbon management at the University of Edinburgh, UK, the accounting within the balance sheet for the carbon budget 2018 was robust.

“Its message is more brutal than ever: we are in the red and still heading deeper. This cannot continue. It must not. To give us a chance of meeting the Paris climate goals, emissions need to fall, and fast. We knew this in 2015, we know it now. And yet they still rise.” – Climate News Network

Biofuel land grab will slash nature’s space

Growing enough greenery to provide cleaner fuel and slow climate change will need a biofuel land grab: a 10 to 30-fold rise in land devoted to green crops.

LONDON, 21 November, 2018 − Replacing fossil fuels with alternatives derived from some natural sources may be prohibitively high: the biofuel land grab needed could require at least 10% more land than the world uses now to grow green crops, conservationists say.

But that’s the good news. They believe the total increase in green energy-related land use could be much higher, closer to 30%, meaning “crushing” pressure on habitats for plants and animals, and undermining the essential diversity of species on Earth.

Their warning was spelt out at a UN biodiversity meeting in Egypt by Anne Larigauderie, executive secretary of the Intergovernmental Platform on Biodiversity and Ecosystem Services, IPBES.

IPBES says it exists to organise knowledge about the Earth’s biodiversity to offer information for political decisions globally, like the work over the last 30 years of the Intergovernmental Panel on Climate Change, the IPCC.

Extremely urgent

She said the latest IPCC report, on limiting climate warming to 1.5°C, had given “a sense of extreme urgency for these exchanges on tradeoffs and synergies between climate, biodiversity and land degradation.”

Dr. Larigauderie said most IPCC scenarios foresaw a major increase in the land area needed to cultivate biofuel crops like maize (or corn, as it is also known) to slow the pace of warming by 2050 − up to 724 million hectares in total, an area almost the size of Australia. The current amount of land used for biofuel crops is uncertain, but conservationists say it lies somewhere between 15 and 30m ha.

“The key issue here is: where would this huge amount of new land come from”, she asked. “Is there currently such a large amount of ‘marginal land’ available or would this compete with biodiversity? Some scientists argue that there is very little marginal land left.

“Protecting the invaluable contributions of nature to people will be the defining challenge of decades to come”

“This important issue needs to be clarified, but the demand for land for energy will almost certainly increase, with negative consequences for biodiversity.”

Dr. Larigauderie was speaking at the start of the annual conference of the states which support the UN Convention on Biological Diversity.

Deep cuts in the greenhouse gas emissions from human activities which drive global warming would be possible without massive bioenergy resources, she said, but this would need substantial cuts in energy use as well as rapid increases in the production of low-carbon energy from wind, solar and nuclear power.

Safeguarding the variety of plant and animal species and the services nature provides was itself essential to reducing global warming, she said. Land ecosystems today soak up about a third of annual carbon dioxide emissions, with the world’s oceans accounting for about another quarter annually.

Forests achieve more

In any case, Dr Larigauderie said, reforestation was better at protecting the climate than most biofuel crops. In temperate climates, one reforested hectare was four times more effective in climate mitigation than a hectare of maize used for biofuel.

“All methods that produce healthier ecosystems should be promoted as a way to combat climate change”, she said. “This includes afforestation and reforestation, as well as restoration − implemented properly using native species, for example.”

IPBES plans to publish a primer detailing elements of its Global Assessment of Biodiversity in May 2019. The British scientist Sir Robert Watson, formerly chair of the IPCC and now chair of IPBES, says: “The loss of species, ecosystems and genetic diversity is already a global and generational threat to human well-being. Protecting the invaluable contributions of nature to people will be the defining challenge of decades to come.

“Policies, efforts and actions − at every level − will only succeed, however, when based on the best knowledge and evidence. This is what the IPBES Global Assessment provides.” − Climate News Network
