Energy Bill [HL]

Report (1st Day) (Continued)

Clause 111: Modifications of the gas code

Amendment 53

53: Leave out Clause 111 Member’s explanatory statement This amendment, along with the amendment in the name of Lord Teverson to leave out Clause 112, would remove the Hydrogen Grid Conversion Trials from the bill.

My Lords, the intention of my amendment is quite stark and seeks to take out those provisions which allow the so-called hydrogen village experiments to take place. Why? Primarily to save British taxpayers a huge amount of money on something which is clearly, as one would colloquially say, a white elephant. Even if we had the trials—which I suspect might not happen anyway for various reasons—the lessons from those would show us that this should not be rolled out.

In order to have clean hydrogen, it has to be produced by electrolysis. There are other ways of producing hydrogen, as we know, and there are all the different colours, but at the end of the day we have to use electrolysis in the long term to produce hydrogen that is seen as a renewable fuel. The cost of that hydrogen is estimated by scientists to be something like five times the cost of the electricity used to generate an equivalent amount of heat through an efficient heat pump—it is five times more expensive. Even if we talk about economies of scale, there is no way that that cost is going to come down; in fact, it would come down only in relation to the cost of renewable electricity itself, which is its source of energy.

I suggest that we scrap this plan because clearly science says that this is not the way to use hydrogen for heating. I am a great fan of hydrogen, as I am sure most people in this House are, and it needs to be used for certain applications for which it is very difficult to use other renewable resources. We know what those are: they include a number of industrial processes and heavy transport, and it may be used for trains in certain areas and for heavy goods vehicles for some while. It is important that we use hydrogen for those purposes. It can never ever be used as a grid gas as methane is at the present.

Let me give an example of what perhaps is an even better way of achieving what we are doing. Down in my own neck of the woods, in Cornwall, we have a scheme financed by the fag end of ERDF funding. A village called Stithians has put in ground source heat pumps as a street utility, much as you would with a gas grid. I suspect that this is far more economical, and it is also liked by the residents. There have been demands for other streets in the village to have the same application.

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.

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.

At the moment, it feels very much as though this was an idea conceived of by two gas distribution companies that considered it a good idea, went to the local councils where they operate and said, “This is what we would like to do. Are you in?”. They said yes, so the companies went to Ofgem, got some money, talked to BEIS and went off on their merry way, forgetting to consult the people who live in the villages that they had identified to ask their opinion on this matter. In Committee I referred to them as

“the villages of the damned”,—[Official Report, 12/12/22; col. GC 95.]

which is colourful language, but it triggered conversations in Whitby in particular. I have had handwritten letters and emails from a number of residents thanking me for highlighting their plight. They very much felt that they were being ignored, overridden and ridden roughshod over by the gas industry in their area, assuming that they would simply comply with the idea that they should be the guinea pigs, as they see themselves, in this trial.

As pointed out by the noble Baroness, Lady Sheehan, it is an unnecessary trial because 33 or 37 independent reports have already been written on the subject of whether 100% hydrogen should be used for home heating, and the overwhelming evidence from independent assessors is that it is not a good idea. It is not a good substitute for the current system and is inferior to much better options. The noble Lord, Lord Teverson, referenced the fact that we can use district heating, with heat loops, ground source heat pumps and individual air source heat pumps. All these, running off electricity or waste heat, would be infinitely more efficient than taking hydrogen, which will be a valuable and expensive carrier of energy—it is not an energy source in its own right—and using it to heat our homes.

For all those reasons, I am very sympathetic. I would like to hear from the Minister precisely what we are trialling here, other than the two gas distributing companies’ ability to do this. What are we seeking to find out? What answers are the Government seeking to make the decision about whether we should continue this idea? Some clarity about that would be helpful for us to understand why we need this provision.

It is very worrisome that the same powers used at the moment for entry into homes to fit prepayment meters are here being extended to the fitting of much more complex works in people’s homes. That power has been suspended by the courts in the UK because it has not been applied correctly—vulnerable customers were not being looked after in prepayment cases—so why do we think we should extend the power when they have failed to apply it properly for prepayment meters? It certainly feels wrong to be rushing to give them more powers at precisely this time.

My final point is about cost. I would like to hear from the Minister how much it is costing. We have tried asking this question in a number of ways. How much is being put aside by the department and Ofgem for these trials? If it is the rumoured £100,000 per household, that is a huge sum of money. Anybody providing any kind of electrification, energy efficiency or heat pumps would do wonders with that kind of money; that would be a far better trial and a better use of public money and our time and effort.

I fully support this group of amendments. I hope this is not the last we will hear of this debate; I am sure it will pass down to the other end. I am grateful that the regulations will now be on the basis of “must”, not “may”. I do not think that goes far enough, but I look forward to the Minister’s reply.

My Lords, I offer Green support for the amendments in the names of the noble Lord, Lord Teverson, and the noble Baroness, Lady Sheehan. The economic arguments for why hydrogen as a home heating mechanism makes no sense at all have already been very clearly made. I aim not to repeat anything that has been said but simply to add a couple of points to it. I very much agree with the point made by the noble Baroness, Lady Worthington, about prepayment meters; that was written in very large letters on my paper, but I have now crossed it out since it has already been covered.

In this debate we have not perhaps highlighted the degree of physical disruption. The noble Baroness, Lady Worthington, referred to receiving many expressions of distress from the affected villages; I have also received those. In the Government’s own terminology, research shows that it will

“undoubtedly result in some physical disruption to the property.”

Those are the Government’s own words. What that actually means is that we will have to see pipework surveyed and possibly changed; gas meters replaced; boilers, gas hobs and gas cookers replaced, as well as four-inch ventilation holes in the area of the boiler and the appliance to make it compatible for 100% hydrogen. The biggest challenge of all, perhaps, is the small in-house pipes that may frequently be embedded in walls or underneath floors. Think about the kind of disruption in an older house; just tracking those down, finding where they are and establishing whether they are adequate for hydrogen is massively disruptive. Every home will have to be checked and double-checked to make sure it is safe before hydrogen can be piped into it.

The other safety point that has not been raised yet, but I think really should be, is that burning hydrogen in the air produces nitrous oxides, which are a pollutant in their own right. It is often said that when you are using hydrogen, water is the only by-product, but that is the case only when hydrogen is used in fuel cells. Nitrogen dioxide is a key air pollutant that is harmful in its own right and is a precursor to other concerning materials including fine particulate matter and ozone.

My Lords, I thank the noble Lord, Lord Teverson, and all other noble Lords and Baronesses who have spoken. While I may agree with the noble Lord, Lord Teverson, that these trials are not a good thing, they are upon us and therefore we have to deal with what we face rather than what we might not have faced had we stopped the trials in the first place. I do not think the Government are about to abandon the plan, and therefore we have some concerns about the plan as it goes ahead.

Clause 111 makes certain modifications to the Gas Act 1986 so that the person running the trial has clear grounds to enter property. That causes me concern that they can carry out essential works and safety checks and disconnect gas supply. Can the Minister deal with some questions? He may not be able to deal with them tonight and may want to write to me later. When can property be entered? What safeguards will be in place? What burden of proof will be applied on entry? When can a property not be entered? Will future guidance be published and, if so, when can we expect it to be with us? The Labour amendment

“requires the Secretary of State to take a number of steps with regard to the areas and people affected by hydrogen grid conversion trials and to make arrangements for Ofgem to provide information, alternative heat sources and offer the right of opt out (which would disapply the right of gas transporters to enter premises to disconnect). It would also require the Environment Agency to monitor and report on hydrogen escape, and the Health and Safety Executive to monitor safety implications.”

Subsection (1) provides the Secretary of State with a power to make regulations by statutory instrument to require a person conducting the trial to follow specified steps to ensure consumers are appropriately informed about the trial and the need for them to be disconnected from their gas supply before it happens. This clause also provides the Secretary of State with a power to make regulations to introduce consumer protections for people who are, or are likely to be, affected by the trial, and a list of examples is provided.
