Hydrogen Supply Chains

Roz Savage Excerpts

Tuesday 9th September 2025 Westminster Hall

[Dr Roz Savage (South Cotswolds) (LD)]

It is a pleasure to serve under your chairmanship, Mr Betts. I thank the hon. Member for Rushcliffe (James Naish) for securing this debate, and the hon. Member for Worcester (Tom Collins) for leading it with such competence and aplomb.

Hydrogen has long been talked about as the fuel of the future, and we are beginning to see how it can be the fuel of the present. If we are serious about net zero, energy security and building the industries of tomorrow, hydrogen must play a central role. Electrification is advancing rapidly but, as we know, about 80% of global energy demand is still for molecules, not electrons. Heavy industry, transport and heating remain stubbornly difficult to decarbonise. Hydrogen offers us a way forward. It is flexible, storable and able to integrate with existing infrastructure. Hydrogen can be partnered with offshore wind in tanks under the water, reducing the need for pylons. It could reduce the need for oversized solar farms on agricultural land, which reduce the land available for food production. But if the UK is to reap the benefits, we must act with urgency. The Hydrogen Innovation Initiative has calculated that securing just 10% of the global hydrogen technology market could deliver £46 billion per year to our economy by 2050 and support over 400,000 jobs. That is a huge opportunity, but it will not wait for us. Other countries are also moving fast and if we are too cautious, we risk being left behind.

In my constituency of South Cotswolds, we see a glimpse of what that future could look like. In just three years, a start-up called Wild Hydrogen has grown from a small lab team to employing 18 skilled people. It is exploring ways to turn waste into clean hydrogen and biomethane, with the added benefit of capturing carbon. The company’s aspiration is bold: the idea that Gloucestershire could possibly host the world’s first carbon-negative town before the decade is out.

Another exciting young company, which is clearly hosting numerous MPs, is ZeroAvia, based at the Cotswold airport in my constituency. As already described by my hon. Friend the Member for Bath (Wera Hobhouse), ZeroAvia is developing hydrogen-powered planes with enormous potential to disrupt the aeronautical industry.

Whether or not those specific goals are realised, the principle stands: innovation is happening already here in the UK. What is missing at the moment is the scale of investment and policy certainty to move from promising prototypes to production at pace. This debate is extremely timely. We have a chance to shape the supply chains, the regulatory framework and the financial environment that will allow British firms to thrive and lead in this vital sector. If we succeed, the prize is not only economic but environmental: cleaner air, lower emissions and a more resilient, self-sufficient energy system. I echo the hope expressed by my hon. Friend the Member for Caithness, Sutherland and Easter Ross (Jamie Stone) that this technology enjoys genuine cross-party support. Let us match the boldness of the innovators in my constituency and beyond with equal boldness in our policy. That means backing domestic supply chains, ensuring the right market signals are in place, and providing the certainty that investors and communities need. If we truly seize this moment, the UK can lead the world in clean hydrogen.
