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.

[Lord Teverson (LD)]

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.

This is in contrast to the towns in these experimental areas. As I judge it—my postbag says this to some degree, although I hear it from others as well—there is a mounting resistance to these trials going ahead. There is no great trust in hydrogen as a domestic fuel because of its properties—its ability to escape and its high flammability. These amendments take out Clauses 111 and 112, so that we can stop these trials and use hydrogen far more effectively. The money saved can also be used more effectively for decarbonisation in other areas as well. There is consumer resistance.

Assuming that the Minister is not going to accept this amendment, I have tabled another amendment arising from conversations with people involved in these trials. Many people want to opt out of them, and I fully sympathise with that. In Committee, the Minister said that households could opt out. What would the compensation be in such a case? Will the Government ensure that households can keep gas or methane, as at present? Can they guarantee this? If not, will they provide other forms of heating appliances, either electrical or an alternative form of heat and energy? Can they guarantee that there will not be forced entry into homes to make sure that the conversion takes place? I will be interested to hear from the Minister the alternatives to participating in the trial, as will people in the trial villages.

I cannot see that these trials will go ahead. There is considerable consumer resistance, and all the science genuinely says that this cannot work on a larger scale. Even if the trials do go ahead, there is no way that hydrogen is going to replace methane in the national grid or in large local heating systems. This can be done in far better ways, and the Bill allows for that. Let us call a halt to this now, save money, ease local concern and concentrate hydrogen in the areas where it can contribute and is important for our transition to a net-zero economy. I beg to move.

[Baroness Sheehan (LD)]

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.

[Lord Callanan (Con)]

As I said, the powers that we propose to provide are essentially similar to those that the networks already have on the basis of essential safety works. Still, I am happy to provide the noble Lord with further information and details.

[Lord Teverson (LD)]

My Lords, when the IPCC report on the global warming challenge came out last week, and it gave a pretty dire view, the Secretary-General of the United Nations, António Guterres, who I think had just been watching the Oscars, said it was

“everything, everywhere, all at once”—

but I do not think he would have included the village hydrogen trials within that broad definition. I understand what the Minister has said, and I welcome all his assurances to local citizens about how the trials will work, but, frankly, the science clearly says that hydrogen sent through the gas pipe network to a range of residential properties does not work, does not make sense and is not going to happen in the future.
