My Lords, I realise that I am a little late arriving for this debate. Having been here from the start of this afternoon’s proceedings, I hope that the House will allow me to make my contribution.

I will speak to Amendments 53, 54 and 57, in the name of my noble friend Lord Teverson. I support Amendment 56 in the names of the noble Lord, Lord Lennie, and the noble Baroness, Lady Blake. I will not bore your Lordships’ House with the details of why my name appears on Amendment 56 in the Marshalled List with a line through it. Suffice it to say, I support the measures in it.

However, I support even more strongly Amendments 53, 54 and 57, which aim to get rid of the hydrogen trials altogether. Although hydrogen has a role in decarbonising our future in many sensible ways, domestic heating is categorically not one of them. I would recommend anyone who is not convinced by that statement to look at the work of the Hydrogen Science Coalition, a group of independent academics, scientists and engineers who give their time voluntarily and have no public or private vested interests. Its briefing is very clear on how it arrives at its conclusion that there is overwhelming evidence against the use of hydrogen for heating homes in the UK and in favour of using heat pumps and district heating networks. Equally, it makes a well-argued case against the provisions of Clause 111 that compel consumers to take part in hydrogen heating trials, not least because the introduction of hydrogen into UK homes will significantly increase the risk of serious explosions and fires, as well as increasing exposure to NOx emissions, which pose a significant public health risk.

To back up its own analysis, it cites the overwhelming techno-economic evidence against the use of hydrogen for heating buildings compared with other sources. There have been 37 independent studies on the use of hydrogen for heating since 2019, by organisations such as the IPCC, the IEA, McKinsey, Imperial College London, the Potsdam Institute, the University of Manchester, the Wuppertal Institute, Element Energy, the International Council on Clean Transportation, the Energy Transitions Commission, et cetera. Every one of these studies has ruled out hydrogen playing a major role in heating buildings because it will be too expensive and inefficient compared to other clean alternatives such as heat pumps and district heating. Too expensive is putting it mildly; it will be six times more expensive than going down the heating networks route.

Chris Skidmore, chair of the net zero review, said in a recent article in the Times that he

“did not think the UK should embrace the idea of repurposing gas networks to run hydrogen boilers, a proposal that is being trialled at a pilot project at homes in Ellesmere Port in Cheshire.”

The House of Lords Environment and Climate Change Committee recently said that hydrogen is

“not a realistic replacement for natural gas”

and is “not a serious option” for heating. A House of Commons Science and Technology Committee report in December 2022 said that hydrogen is likely to play only a limited role in home heating and is not a panacea. Lastly, in a report in January 2022, the International Renewable Energy Agency—IRENA—said that residential heating is the lowest-priority application for hydrogen

“because heat pump solutions and district heating options already exist.”

I apologise for labouring the point but it is important for the people in the trial villages of Ellesmere Port and Teesside. The provisions of the Energy Bill that give gas companies a new power of entry into homes to cut residents off the gas network without their consent are particularly worrying. The bottom line is that the Bill should not be promoting hydrogen heating trials that expose consumers to health and safety risks and excessively high energy costs.

My Lords, I will speak to the amendments in this group but I do not propose to detain the House for long. My views on hydrogen are relatively well known, and we had a good debate in Committee on Clauses 111 and 112. I support the previous speeches and the approaches taken to get the Government to think again about the need for these trials to be included in the Bill.

I welcome government Amendment 55, which would provide for regulations that would make some rules for the trials a “must”, rather than a “may”, which is at least an acceptance that this is a prerequisite. We need clear regulations setting out the rules that must be adopted and followed by anyone involved in these trials. But I do not think that goes far enough, because there are still a number of unaddressed issues. Therefore, I am quite sympathetic to the idea of simply removing this from the Bill and thinking again. I am also sympathetic to the proposal by the noble Lord, Lord Lennie, and the noble Baroness, Lady Blake, who have suggested that the Government ought to undertake a certain number of measures before they embark on a decision about these trials, including involving statutory agencies such as the Environment Agency in the trials, and the Health and Safety Executive on safety issues, so that we can properly assess their environmental impact—so that we actually are using them to trial something.

--- Later in debate ---
I hope that, with the explanations I have been able to provide, the noble Lord, Lord Teverson, and the noble Baroness, Lady Sheehan, will appreciate that the purpose of the trial is to provide important evidence for the strategic decisions that we will need to make on the future of heat decarbonisation. I hope that they have been reassured that these clauses are necessary for the safe and effective delivery of the trial, and will therefore consider withdrawing the amendment.

I want to press on the question of what is being trialled. The Minister mentioned feasibility, benefits and costs, but what about the environmental impacts of this trial? We are talking here about a global warming gas, and a very slippery gas because it is the smallest element—it escapes everywhere. Will the regulations contain measures to monitor the environmental impact of both the NOx emissions in the home and the greenhouse gas impact of the hydrogen, which will leak when it is distributed that widely? Can that be included in the trial so we can also assess those disbenefits?

Finally, it is true that the only reason really that some houses might not qualify for a heat pump is if they are not very efficient. It is ironic that, for safety reasons, the leakier the house, the more likely it is to then be able to take hydrogen. This precious commodity, which is very expensive to produce and will be very inefficient, is being used in houses which are leaky and being made leakier to be made safer. It seems just so counter to everything we want to achieve on efficiency, resilience and climate change. I hope there will be a trial of the environmental impacts on air quality, climate change and energy efficiency, not just the benefits to the gas industry.

I know the noble Baroness has strong views on electrification but let me reassure her that this is precisely the purpose of the trial. We need to use an existing network to find out what happens to hydrogen in an existing network. Clearly, environmental monitoring and checking for leaks and so on is a crucial part of it. It is one of the reasons we need to do it on an existing network in an existing community, to find out what happens outside of theoretical lab experiments where it is very easy to set up a trial with new pipework, new valves and new equipment. I have visited hydrogen demonstration houses up in Gateshead, my home area. It works very well but these are brand new properties, constructed with hydrogen appliances and new pipework. That is not a very good trial as to how it would work in the real world in existing communities. That is why we need to do the trial. The things that the noble Baroness asked about are exactly what we need to be checking and monitoring to judge the effectiveness of any hydrogen experiments in the real world.

I turn to Amendment 56, tabled by the noble Lords, Lord Lennie and Lord Teverson, and the noble Baroness, Lady Sheehan. This amendment covers several aspects which I fully agree are important for the safe and effective delivery of the village trial. However, I assure noble Lords that the evidence that this amendment seeks to gather through a statutory consultation is already being gathered and will be reviewed by the department as part of our assessment process, following the submission of final proposals at the end of this month. As I said, in May 2022, we sent a joint letter with Ofgem to the gas networks setting out an extensive list of requirements that proposals for the trial should meet. This included requirements mentioned in the amendment, such as local support, costs, environmental impact and consumer protections, as well as many other important areas.

After the gas networks submit their proposals for the trial—later this week, as I said—the department will undertake a thorough assessment against the full list of requirements set out in the letter. That process will involve expert input from the various statutory bodies involved, including the Health and Safety Executive and Ofgem. We will publish the result of that assessment later this year, including the relevant evidence to explain our decision, and that will be available to all noble Lords. I reassure the House that we fully understand the importance of conducting the trial properly.

I touched on this earlier but the noble Lord, Lord Teverson, raised the point about local support for the trial. I reiterate that we will go ahead with a trial only in an area where there is strong local support. The gas networks are working closely with local authorities, communities and Members of Parliament as they develop their trial proposals. My officials also meet regularly with the relevant local authorities. Final proposals for the trial will need to contain evidence of strong support from the local community, validated by an independent external source, such as a local council. Again, I am happy to meet the local Members of Parliament.

The networks are extensively consulting local residents to develop an attractive consumer offer tailored to the community. They have opened drop-in centres in both Whitby and Redcar where anyone can engage directly with them and ask questions about what the project means for them, and have held a number of public events.

Safety is of course fundamental, which is the point made by the noble Baroness, Lady Sheehan. Before any community trial can go ahead, the Health and Safety Executive will need to be satisfied that the trial will be run safely. No trial will go ahead until all necessary safety assessments have been successfully carried out. I hope noble Lords will accept my reassurances on that.

If it goes ahead, the trial will start in 2025 and provide vital evidence that will be required to enable the Government to make decisions in 2026 on any potential future role for hydrogen in decarbonising heat. I hope noble Lords will accept that undertaking another formal consultation would duplicate the work that the department and the gas networks are already doing, and could delay important milestones for ultimately meeting net zero.

I agree that the trial must be conducted properly, and I have already spoken about the additional consumer protections that will be in place for the trial. Those protections, which must be met by the gas networks, also mean that the trial must be delivered with minimal disruption to consumers.

I hope I have been able to reassure noble Lords that the department will carefully consider all these factors in coming to a decision on the trial. Importantly, we will be closely examining the evidence and outcomes of the gas networks’ engagement with local authorities and consumers in the trial areas. I hope that, with the reassurances that I have been able to provide, the noble Lord, Lord Teverson, will consider withdrawing his amendment.
