The price cap will rise by £63 in October, the third increase this year. Yet buried in the same week’s energy news is a quieter number: £500,000, awarded by Ofgem to a hydrogen storage project in the UK. That sum, as reported by The Chemical Engineer, is not a lot in energy infrastructure terms, it would barely cover a single heat pump installation on a hundred homes. But it signals something bigger: the government is betting that hydrogen will store surplus wind and solar power for use when the wind doesn’t blow.
What the grant actually pays for
The money goes to a project developing underground hydrogen storage, likely in salt caverns or depleted gas fields. The idea is simple: when renewable generation exceeds demand, electrolysers split water into hydrogen and oxygen. That hydrogen is stored, then burned in power stations or used in homes when demand spikes. Ofgem’s Strategic Innovation Fund, which handed out this grant, has previously backed hydrogen heating trials in neighbourhoods from Fife to Gateshead. But storage is the missing piece. Without it, hydrogen heating advocates cannot promise a reliable winter supply. The £500,000 will fund feasibility studies, not construction. Actual storage caverns cost tens of millions. So this is a paper exercise, albeit an important one.
What this means for household bills, now and later
Your October bill will rise because of gas and electricity wholesale costs, not because of hydrogen R&D. But the long-term logic is worth understanding. If hydrogen storage works, it could reduce the need for gas-fired power stations to sit idle, burning fuel on standby. That would lower capacity market charges, about £10 a year on a typical bill, and eventually displace some gas use. The catch? Hydrogen is currently about four times more expensive than natural gas per kWh. Even with a carbon price, it won’t compete until production scales up. The government’s own 2021 Hydrogen Strategy admits that ‘hydrogen heating is unlikely to be the main solution for most homes’. Heat pumps, district heating, and insulation are the priority. Hydrogen is a hedge, not a plan.
Who qualifies, and who doesn’t
No homeowner can apply for this funding. It is not a grant for your house. But the project’s location matters: if you live near a salt basin, Cheshire, Yorkshire, or the East Midlands, you may see hydrogen trials in the next decade. For everyone else, the practical takeaway is this: the Boiler Upgrade Scheme offers £7,500 off a heat pump right now. The Great British Insulation Scheme covers cavity wall and loft insulation for eligible households. Neither requires hydrogen. Both improve your EPC rating and cut bills immediately. Waiting for hydrogen is like waiting for a bus that hasn’t left the depot.
Three things to do this week
First, check if you qualify for the Boiler Upgrade Scheme via gov.uk. Second, book a free cavity wall inspection through Energy Saving Trust. Third, read the 2023 Climate Change Committee report on hydrogen, it concludes that ‘hydrogen for home heating is not a near-term decarbonisation route for the majority of homes’. The £500,000 grant is a useful experiment. Your heating upgrade is a decision you can make now.
Frequently Asked Questions
Not directly. The £500,000 grant funds feasibility studies, not construction. If the project leads to commercial storage, it could reduce grid balancing costs by the 2030s, shaving perhaps £10-£20 off annual bills. But don't expect any change in the next five years.
No. The Climate Change Committee and government both advise that heat pumps and insulation are the primary route to decarbonising homes. Hydrogen heating is still unproven at scale and likely more expensive. Install a heat pump now with the £7,500 Boiler Upgrade Scheme grant rather than waiting a decade for a hydrogen boiler that may never come.
