Repair the Planet publication: Carbon seize energy stations are again
Will fuel energy stations outfitted with carbon seize and storage be the way forward for energy vegetation within the UK?

What does the ability station of the long run appear to be to you? Fleets of wind generators and rows of photo voltaic panels would possibly spring to thoughts. Within the UK, it’s more and more clear that offshore wind farms are going to be the spine of the nation’s vitality system due to economics, emissions and the ecosystem of firms supplying them right here. Alongside these, we’re going to want much more vitality storage, extra energy hyperlinks to different nations and extra vitality effectivity.
But it surely’s additionally a sensible risk that we’re going to want different energy stations that may be fired up at will for when we've mini wind droughts or spikes in demand. I took the prepare as much as Scunthorpe in Lincolnshire final week to satisfy Alistair Phillips-Davies, the chief government of vitality large SSE, and listen to about his plans to construct the world’s first hydrogen energy station and one other potential first, a fuel energy plant outfitted with carbon seize and storage (CCS).
So, what would these energy stations appear to be?
I travelled to the extremely flat panorama that's house to Keadby 2, an 893-megawatt fuel energy station in east England that SSE has just about completed. It should nearly actually be the UK’s final fuel energy station with out CCS. Looking from the roof of its cooling towers, nevertheless, you'll be able to see two fields that SSE hopes to show into Keadby 3. If it will get constructed and comes on-line in direction of the top of this decade, it could be the world’s first fuel energy station with CCS (it faces competitors for the title from one other venture, at Peterhead in Scotland). In concept, it ought to seize about 95 per cent of the plant’s carbon dioxide, says Phillips-Davies. Exhaust gases from the plant shall be run by way of a liquid, sucking up the CO2, earlier than it’s compressed and transported by way of a pipeline that doesn’t exist but. That may whisk the carbon dioxide away for storage in an outdated oil and fuel reservoir beneath the seabed. Once more, such a facility must be constructed.
Hold on, haven’t we been right here earlier than with CCS energy stations?
With coal, sure. It didn’t work out effectively. There have been some small-scale pilots within the UK, together with one at Ferrybridge, a now-closed coal plant that isn’t one million miles from Keadby. There may be one large-scale coal energy station with CCS working in Canada, however it hasn’t carried out in addition to hoped. There seems little urge for food globally for additional coal energy with CCS. However Phillips-Davies thinks fuel vegetation with CCS could be completely different and could possibly be a cornerstone of assembly the UK authorities’s objective of a totally decarbonised energy system by 2035. He concedes fuel costs are “very uncommon” in the meanwhile (learn: document highs), however doesn’t assume that undermines the case for his imaginative and prescient.
What are the indicators that Keadby 3 will ever be greater than an artist’s impression?
Phillips-Davies says hundreds of thousands of kilos have already been spent and notes that SSE has earmarked “tons of of hundreds of thousands” for future CCS and hydrogen tasks. The planning course of has already began (SSE was holding a gathering with native folks 10 minutes away on the day I visited, and an preliminary session closes on 20 March). However till a closing funding resolution is made, it stays a proposal quite than a agency guess. Richard Howard at analysts Aurora Power Analysis says the ability station would clearly want some type of new authorities assist to make it occur.
And what concerning the hydrogen plant?
Subsequent to the fields the place Keadby 3 would possibly sit are automobile parks and cabins that could possibly be moved to make method for Keadby Hydrogen. It could be the world’s first massive hydrogen energy station, if accomplished this decade as hoped by SSE and its associate, the Norwegian oil and fuel large Equinor. Up to now, most makes use of of hydrogen for electrical energy era have been small scale and concerned gas cells in buildings, quite than burning the stuff to energy generators. The proposed new energy station would arguably be much more formidable than the CCS fuel one, as a result of nobody has tried something like this earlier than. “On paper it sounds nice,” says Jess Ralston on the Power and Local weather Intelligence Unit, a UK-based assume tank.
That is the place you’ll inform us the supply of the hydrogen is necessary, proper?
You’re one step forward. Nearly the entire world’s hydrogen at the moment is constituted of fossil fuels, producing carbon emissions equal to these of the UK and Indonesia collectively every year. So the brand new plant will should be fuelled with inexperienced hydrogen (made utilizing renewable electrical energy and electrolysers) or blue hydrogen (reformed from pure fuel with the CO2 captured and saved). Equinor is planning a blue hydrogen plant simply up the street from Keadby Hydrogen, at a venture known as H2H Saltend.
Phillips-Davies says he thinks some blue hydrogen is the “proper solution to begin”, to have sufficient volumes accessible and since it’s prone to be cheaper than inexperienced hydrogen. Nevertheless, he says: “In the end, I believe you need to get to inexperienced. Once we construct an increasing number of of our massive wind farms offshore, I believe then we’ll get into inexperienced hydrogen. We’re doing numerous work on what measurement an electrolyser fleet can SSE personal by the top of this.” For now, he says low-carbon hydrogen consumption and manufacturing merely must get going. “The hydrogen journey is simply beginning.”

- The European Union has unveiled a plan to chop out two-thirds of its Russian fuel imports by the top of the yr, in a significant pivot to different fuel sources and renewable vitality following Russia’s invasion of Ukraine. Story right here.
- Information that a lot of the Amazon has misplaced resilience and is nearing a tipping level earlier than it collapses into savannah might not look like a Repair. However specialists be aware that the brand new analysis might help prioritise conservation efforts in direction of areas most probably to resolve, protecting billions of tonnes of carbon locked away.
- We’ve lined CO2 removals a lot in New Scientist. Others are additionally more and more taking them severely. The Power Transitions Committee, a bunch backed by vitality firms, yesterday laid out the dimensions of the problem: it thinks between 70 and 225 billion tonnes of CO2 wanted to be eliminated between now and 2050.
