UK gas plans a carbon-free future with hydrogen

Committed to a carbon-free future by 2050, the UK gas industry is to switch to green hydrogen and biogas.

LONDON, 20 April, 2020 − A mixture of green hydrogen produced by surplus solar and wind power and bio-methane coming from farms and waste food will ensure the British gas industry a carbon-free future in 30 years, according to the country’s gas network operators.

The ambitious plans for the first carbon-free gas grid in the world have been declared both technically possible and one of the less expensive options in solving the tricky problem of how to heat UK homes, office buildings and factories, said to be the most difficult task in decarbonising the energy system.

The programme, called Gas Goes Green, involves using the existing gas networks that supply 85% of Britain’s homes, as well as business and industry but converting boilers and other appliances to use hydrogen.

Although the plan is ambitious, its authors, the Energy Networks Association (ENA), which includes the transmission and distribution operators for gas and electricity in the UK and Ireland, point out that a similar programme was carried out in the 1970s to convert the entire British gas grid from supplying coal gas to natural gas.

The plan, which involves 23 million properties, will be closely watched across the rest of Europe and in many other developed countries that have extensive gas networks.

“Gas Goes Green will tackle some of the biggest challenges facing decarbonisation policy”

Currently Europe depends heavily on Russian natural gas, and there have been a number of disputes about pricing which have led to threats to cut off the supply.

This has led to political pressure to find alternatives, with compressed natural gas imported from the Middle East and the US a candidate to provide a possible alternative supply.

Now the pressure is on to decarbonise the sector entirely. The UK is well placed to do so because it has enormous potential for producing far more electricity than it needs from renewable sources: wind, solar and various tidal and wave schemes.

The aim of going carbon-neutral by 2050 is enshrined in UK law, but the country’s new Conservative government, elected last December, has yet to come up with a plan for achieving this. Clearly, though, the gas industry thinks it has found a solution.

The big argument so far has been that green hydrogen, produced by electrolysis from electricity, is too expensive to compete with hydrogen produced from natural gas. However, with electricity from renewable fuels falling in price and becoming ever more plentiful, the economics of green hydrogen are expected to compete with what gas can do, the industry argues.

Potential for transport

There is also increasing interest in using hydrogen for transport, including trains, to avoid the expense of electrifying lines. It has a distinct advantage over electricity: it can be stored for long periods.

ENA commissioned a report from the accountants KPMG which concluded that conversion from natural gas to hydrogen was both technically feasible and one of the cheapest options for the nation’s heating systems.

ENA, whose members pipe gas to 21.5 million UK customers, finally came up with its plan: to switch its networks entirely to hydrogen and biogas.

There are already a number of schemes that inject both fuels into the national network, and there are experiments with closed systems which provide heating and cooking on 100% hydrogen systems. The industry is confident these could be scaled up.

Matt Hindle, head of gas at ENA, told Business Green: “We’re delighted to not only be launching this exciting new programme, but also to be making clear our commitment to creating the world’s first zero-carbon gas grid.

Political impetus

“Gas Goes Green will deliver the greenprint needed to do that, and in doing so tackle some of the biggest challenges facing decarbonisation policy.”

The first step will be to work out a plan to switch UK boilers from burning natural gas to a mixture that is mostly hydrogen but contains some bio-methane.

This ambitious plan faces some competition from the advocates of ground-source heat pumps as an alternative for heating homes. The pumps have the advantage of running on green electricity, and cut out the need for gas entirely, but they need to be installed in large numbers.

The pumps’ supporters argue that scaling up green hydrogen production to fulfil the entire needs of the gas network is nearly impossible in the 30 years left until the UK should have reached carbon neutrality.

What is interesting, however, is that a number of competing technologies now exist to decarbonise heating, cooking and transport entirely. All that is still lacking is the political will to press ahead. − Climate News Network

Plentiful renewable energy awaits the world

Cheap and plentiful renewable energy is possible: pure hydrogen power in the ground, enough wind in European skies to power the world.

LONDON, 29 August, 2019 − US and European researchers have shown the way to an era of cheap and plentiful renewable energy on a massive scale.

Canadian scientists have worked out how to extract pure, non-polluting fuel from spent or unexploited oil wells at a fraction of the cost of gasoline.

And British and Danish scholars have worked out that, in principle, Europe could generate enough onshore wind energy to supply the whole world until 2050.

Neither technology is likely to be exploited on a massive scale in the very near future. Wind energy development depends on national and local decisions, and the new study is a simple atlas of possible sites across the entire continent.

And although hydrogen is already driving trains, cars and buses in many nations, the technology is still essentially experimental and the infrastructure for a hydrogen economy has still to be built.

“The study does show the huge wind power potential right across Europe which needs to be harnessed if we’re to avert a climate catastrophe”

But both are instances of the sustained ingenuity and imagination at work in research laboratories and institutions as scientists confront the challenge of a world no longer dependent on the fossil fuels that drive global heating and the climate emergency.

The technology that can take hydrogen straight from existing oil reserves was presented at an international geochemistry conference in Barcelona and depends on university-patented technology now being developed by a scientific start-up.

In essence, the bedrock becomes the reactor vessel for a high-temperature reaction involving hydrocarbon molecules and water: oxygen-enhanced air is pumped downwards at the wellhead and injected deep into a reservoir of tar, bitumen or oil to begin a process that raises subterranean temperatures.

At 500°C the hydrocarbons fracture, and a patented system intelligently locates the hydrogen and filters it: the carbon stays in the ground.

“What comes out of the ground is hydrogen gas, so we don’t have the huge, above-ground purification costs associated with oil refining: we use the ground as our reaction vessel.

Steep cost cut

“Just taking Alberta as an example, we have the potential to supply Canada’s entire electricity requirement for 330 years,” said Grant Strem, of Proton Technologies, which is to commercialise the process at – the technology’s begetters say – a cost per kilo of hydrogen of between 10 and 50 cents. This is a fraction of the cost of gasoline extraction.

Hydrogen is in theory the ideal fuel: the visible universe is made of it. The only product of its combustion with oxygen is water. It is already being exploited as a battery fuel: surplus solar and wind power could be used to split water and store hydrogen as a reserve for electricity generation.

Researchers have proposed a hydrogen-powered bicycle, engineers have calculated that hydrogen could replace the world’s natural gas supplies in the next 30 years, and designers have even proposed a safe global bulk carrier hydrogen delivery system by automaton airships more than 2kms long.

Wind power, by contrast, is now a highly developed technology that is already advanced in Europe and the US, and, like solar power, it could supply national grids almost anywhere in the world.

One of the bigger remaining questions is: what is the right place to put a battery of wind turbines? European scientists report in the journal Energy Policy that the ideal of a European grid powered entirely by renewables is now within the collective technological grasp.

Hundredfold increase

A new map based on wind atlases and geographic information identifies 46% of the land mass of the continent that would be suitable for wind turbine generation. If all such space were exploited, the turbines could amplify the existing onshore wind supply a hundredfold and could generate energy equivalent to roughly a megawatt for every 16 European citizens.

That adds up to more than 11 million additional turbines over 5 million square kilometres in large parts of western Europe, Turkey and Russia.

“Our study suggests the horizon is bright for the onshore wind sector,” said Benjamin Sovacool, of the University of Sussex in the UK, one of the authors.

“Obviously, we are not saying that we should install wind turbines in all the identified sites, but the study does show the huge wind power potential right across Europe which needs to be harnessed if we’re to avert a climate catastrophe.” − Climate News Network
