Hydrogen gas blending could hike up customer bills by 20% and barely save any emissions: think-tank
E3G warns that blending could ‘greenwash fossil gas’ and derail heat decarbonisation
Blending hydrogen into the gas network could “greenwash” polluting fossil gas and raise customer heating bills by up to 20% — while only saving a negligible amount of carbon emissions, a UK think-tank has warned today (Thursday).
Hydrogen: hype, hope and the hard truths around its role in the energy transition
Moreover, the government is also keen to produce hydrogen “electrolytically” using grid electricity, which is currently only a maximum of around 50% renewable, depending on wind and solar conditions.
Costs for a 20% blend could rise by just 7% if hydrogen is priced at around double that of fossil gas, but could be as much as three- to four-times as expensive as the gas it is replacing, pushing costs up even further.
However, the differential could be explained by the fact that both of those reports were published before the war in Ukraine, which caused a prolonged spike in gas prices.
The proposal was stripped from the Bill during its reading in the UK’s upper house, the House of Lords, but was reintroduced by ministers in the lower chamber, the House of Commons.
The rules would give ministers power to set the levy from 2025, but so far they have not disclosed how much it would add to bills.
“Precisely how much household bills will increase depends on policy choices — including the level of the blend, government policy to support production, storage and transport, and billing mechanisms,” E3G said.
London is due to make a decision on whether to support hydrogen blending this year.
But blending will not strategically stimulate demand for hydrogen, the E3G said.
Instead, it could risk the UK’s entire decarbonisation goals by locking-in unsuspecting customers to polluting fossil-fuel boilers.
“Blending could risk greenwash if the public are told ‘gas has gone green’, when hydrogen-ready boilers will burn fossil fuels for decades,” the think-tank said in its briefing. “This could delay investment into genuinely zero carbon heating and curtail strategic decisions about the future of the gas grid, including its repurposing or decommissioning.”
