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.

Solar Farms: Agricultural Land

Roz Savage Excerpts

Tuesday 28th January 2025 Westminster Hall

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

I beg to move,

That this House has considered solar farms on agricultural land.

It is a pleasure to serve under your chairmanship, Sir Desmond. We are addressing an issue of great importance: the proliferation of solar farms on our agricultural land.

As many hon. Members know, I have dedicated much of my life to raising awareness about our ecological and climate crises. I have met people who are set to lose their entire countries to rising seas. Let me be clear: nobody can doubt my commitment to strong action on climate change. However, there are many ways to skin the climate cat, and I do not believe that solar parks on the scale of Cottam, Cleve Hill, Longfield, Mallard Pass, Gate Burton, Sunnica and the proposed Lime Down, in my own constituency of South Cotswolds, are the best way forward.

I have received numerous messages from residents near the proposed site of Lime Down. Without exception, they are distressed about the proposal, and I share their concerns. They are not nimbys; they are thoughtful, environmentally conscious people, who, like me, agree that we need renewables but at the right size, in the right places and in the right ownership.

[Rachel Gilmour (Tiverton and Minehead) (LD)]

Like my hon. Friend, I am very keen on renewable energy. I am a Liberal Democrat, for heaven’s sake! However, I am also a pragmatist. In Washford, in my constituency, a massive solar farm is being built on particularly good agricultural land. Would my hon. Friend agree that we must be practical and put solar panels on commercial buildings and residential houses, rather than on farmland?

[Dr Savage]

I thank my hon. Friend for her intervention. I totally agree and will be coming to that point shortly.

[Jim Shannon (Strangford) (DUP)]

I commend the hon. Lady for securing this debate. I suppose the issue is twofold. First, the farmers who sign up to solar farms are committed to a long-term lease, and that will impact the family inheritance tax potential. The second point comes in relation to using land better for food production, as it should be used, so that only land that is of a lesser quality, or rocky land, would be more suitable for solar farms. Does the hon. Lady agree that that is the way forward?

[Dr Savage]

I thank the hon. Gentleman for his intervention and I agree that that is the way forward.

Let us consider the facts. Our agricultural land is dwindling at an alarming rate. We are down to 14.8 million acres of arable land, the lowest amount since world war two, and we are losing nearly 100,000 acres annually. We already import nearly 60% of our food. Do we really want to increase that dependency on foreign supply chains?

[Tim Farron (Westmorland and Lonsdale) (LD)]

My hon. Friend is being super generous and I am grateful to her. She makes excellent points. We obviously have means by which we can control how those things happen, through the environmental land management payment scheme and planning law. Would she agree that, through both of those streams, we should be able to ensure that food security is at least as important as energy security, and that we should not be using productive agricultural land for solar farms when they can be developed elsewhere? Westmorland and Furness Council, for example, has used disused land to provide a solar farm of its own on non-agricultural land.

[Dr Savage]

I agree with my hon. Friend that we should be prioritising locations that do not impact on our ability to meet our food security needs.

The environmental benefits of solar farms are not as clearcut as some would have us believe. Yes, they produce clean energy, but at what cost? Large installations can alter local ecosystems, potentially contaminate soil and even increase local temperatures due to heat absorption by the dark panels—and let us not forget the human cost. Tenant farmers face eviction. Land values are skyrocketing, making it harder for new farmers to enter the industry, and we risk losing the very character of our rural communities that underpins local tourism and our national identity.

[Greg Smith (Mid Buckinghamshire) (Con)]

I agree with every word the hon. Lady has said so far. Does she agree with me that if we are to protect food security and give it equal billing with energy security and national security, not just solar installations are inappropriate, but the ancillary projects like those I am seeing in my constituency? For example, we have battery storage and National Grid coming along and saying it has to completely rebuild all of the substations on—guess what?—more agricultural land. This is a much bigger problem than just solar.

[Dr Savage]

I absolutely agree with the hon. Member’s points. I am not against solar energy—far from it—but we need to be smart about how we implement it and all the associated infrastructure. Why not require all new homes to be fitted with solar panels, as proposed by my hon. Friend the Member for Cheltenham (Max Wilkinson) in his sunshine Bill? Why not use the vast roof spaces of warehouses, public buildings and car parks? These are sensible, minimally intrusive ways to contribute to our net zero goals.

[Edward Morello (West Dorset) (LD)]

I will confess that before being elected to this place, I spent 10 years in renewable energy finance. It is a common claim from certain activists and newspapers that we should put solar on commercial buildings. I do not disagree with that. The problem is the economics of it do not stand up from a finance perspective. Until the Government step in to guarantee a minimum amount of value for export, rooftop solar will never stack up. Neither will carport solar. That is why investors will always go for utility-scale. Does my hon. Friend agree that if we actually want to see a catalyst, if we want to see a change, if we want to see farmers growing crops and not solar panels, the Government need to step in and regulate the market?

[Dr Savage]

My hon. Friend makes some very interesting points that I look forward to exploring further with him in the future. I agree that we need Government to intervene to adjust the incentives so that we can meet our energy needs with the lowest cost to our countryside.

[Pippa Heylings (South Cambridgeshire) (LD)]

Part of the barrier to public acceptance of large-scale solar farms comes from a need to see a joined-up approach and that we are balancing food security and energy security. What people want to see—for example, in my constituency with the large proposed Kingsway solar farm—is the much promised land use framework and the strategic spatial energy framework, so that they know where the 0.1% should go and that it is going in the right places, that there is a joined-up approach, and therefore that reasonable people can support it where necessary.

[Dr Savage]

I am sure we are all waiting with bated breath for the long-awaited land use framework.

The National Farmers Union is well aware that British farmers host about 70% of this country’s solar generation capacity, but it is urging the Government to recognise that small-scale energy needs to be prioritised on brownfield sites and lower quality land first. Let us not forget about other nature-based solutions such as rewilding or planting 60 million trees per year. That would not only help to absorb carbon, but restore valuable habitats.

We do need to increase our use of renewables. However, it must be done sympathetically to the environment and should provide, as a priority, community energy to homes, schools and businesses. We have a real opportunity with the land use framework to define our national priorities for the long-term future, emphasising ways of multi-purposing land with ideas like intercropping, living roofs and rooftop solar.

We absolutely need cross-party consensus. The question of meeting future energy needs while not trashing the climate, our countryside or food production is too important to become a political football. The English countryside is currently at risk of being exploited for financial gain by profit-making companies—a corporate wolf dressed in green clothing. We must not allow that to continue unchecked.
