UK plan to boost hydrogen production relies on fossil fuels

The UK authorities has backed a plan to make use of the manufacturing of hydrogen from fossil fuels with carbon seize and storage to scrub up heavy business. This plan comes regardless of issues that the expertise doesn’t seize all CO2 emissions, stays commercially unproven and perpetuates pure fuel extraction.

Beneath a 120-page hydrogen technique revealed on 17 August, which follows within the wake of comparable plans by the EU and different international locations final yr, the UK laid out the way it will increase hydrogen manufacturing. A strategic choice on the position hydrogen might soak up decarbonising heating in buildings may also be taken inside 5 years, it mentioned.

The Division for Business, Vitality and Industrial (BEIS) mentioned it’s mulling subsidies just like ones for offshore windfarms to deliver down the price of each blue hydrogen, constructed from pure fuel however with a lot of the CO2 captured, and inexperienced hydrogen, the place renewable electrical energy is used with electrolysers that produce hydrogen from water.

“It’s not a shock the UK is backing each,” says Anise Ganbold at Aurora Vitality Analysis within the UK. “It’s what the UK has been pushing for and never a shock given how sturdy the fuel foyer is. In the meanwhile, it’s cheaper to make hydrogen from blue, however we don’t suppose that may final for lengthy. We predict inexperienced shall be cheaper by the 2030s.” Blue hydrogen is opposed by some environmentalists partly as a result of at greatest it solely captures 95 per cent of the CO2, elevating questions over its position in hitting web zero targets.

It’s also untested at a business degree, although Norwegian vitality agency Equinor has plans to construct a blue hydrogen plant close to Hull in north-east England. Jess Ralston at Vitality and Local weather Intelligence Unit within the UK, says: “The federal government ought to be cautious about being lobbied by the fuel business and committing too closely to blue hydrogen, which nonetheless makes use of fossil fuels in its manufacturing and depends on [the] not-yet-ready expertise [of] carbon seize and storage to scale back its emissions.” Storing the carbon at sea, the place the UK has essentially the most storage capability, is also costly, Ganbold provides.

The federal government argues this “twin monitor” will assist the UK meet a goal of 5 gigawatts of low-carbon hydrogen manufacturing by 2030, up on what it says is “virtually no” capability now. “Right now marks the beginning of the UK’s hydrogen revolution,” mentioned vitality secretary Kwasi Kwarteng in an announcement.

By way of utilizing the hydrogen, Ralston says it may very well be very important for decarbonising heavy business, particularly metal manufacturing. Nonetheless, she fears its use in residence heating might delay motion on alternate options, comparable to electrification by means of warmth pumps.

The UK’s technique reveals that the federal government is contemplating mixing hydrogen in with pure fuel provides. BEIS estimates a 20 per cent mix of hydrogen would decrease emissions 7 per cent, however Ralston thinks that’s not sufficient. “On the finish of the day, any proportion of hydrogen mix with fossil fuel within the grid is simply not appropriate with web zero and it’s not but clear how efficient hydrogen shall be, nor how a lot it would price,” she says.

In keeping with the revealed technique, the federal government will set a normal for low-carbon hydrogen that’s “per web zero”. Ganbold mentioned that shall be vital, partially as a result of Scotland has made clear it needs to export low-carbon hydrogen, and a normal will assist commerce.

BEIS additionally mentioned it’s consulting on a £240 million fund for hydrogen manufacturing vegetation, and believes a UK-wide hydrogen financial system might create round 9000 jobs by 2030. The technique envisages 20-35 per cent of the UK’s vitality consumption coming from hydrogen by mid-century.
