Energy Bill [Lords]

Debate between George Eustice and Alec Shelbrooke

2nd reading
Tuesday 9th May 2023 Commons Chamber

[George Eustice (Camborne and Redruth) (Con)]

This is a large and technical Bill that sets in place important frameworks, particularly when it comes to carbon capture and storage and the wider deployment of hydrogen and heat networks. I will address my comments, in the time that I have today, to part 3 of the Bill, particularly the support for low-carbon heating schemes and the opportunity that this provides for doing something creative for the off-gas grid homes in this country. It links to the earlier intervention of the hon. Member for Strangford (Jim Shannon) and to a private Member’s Bill that I introduced at the beginning of this year.

At the moment, we have 1.7 million homes in this country that are currently off the gas grid, most of which use kerosene at the moment. Under the current Government plan, which is born out of a strategy that dates all the way back to 2017—several Governments ago—the intention is that all those 1.7 million homes would be banned from having a replacement boiler after 2026 and told that, instead, they must have, effectively, either an air source heat pump or a ground source heat pump. As the right hon. Member for Leeds Central (Hilary Benn) said, there is a role for those heat pumps, but they are not for every home. In particular, in rural and especially coastal areas, air source heat pumps can be prone to rusting and decay. It is also the case that they need a lot of insulation to make them work, and, in some older homes, high levels of insulation mean less ventilation, which can lead to problems with damp, mould and all of the health problems that go with that.

Perhaps, more important than anything, the capital cost of these air source or ground source heat pumps for a single property is around four times that of a conventional boiler.

[Alec Shelbrooke]

My right hon. Friend touches on a point that I was going to raise later. My concern about the banning of gas boilers from 2024 is the impact that that will have on industry and on farming in particular, especially in relation to those costs. Farming is under a lot of pressure at the moment. Does he agree that this is similar to the argument that he is making about households in 2026?

[George Eustice]

My right hon. Friend makes an important point. As the right hon. Member for Leeds Central said, we need a diversity of different technologies because it is essential that we have all the tools in the box to achieve our objectives.

There is also a wider problem with the current Government strategy. Just before we get to 2026, we can envisage plumbers and boiler engineers across the land going out to people and saying, “If I were you, I would get a new boiler now because the drawbridge is about to come up.” That will probably mean that we will have a surge of investment in boilers at just the wrong time. On top of that, there is likely to be a “mend and make do” approach that will stretch for many years. All of this means that the objective of making carbon reductions, and getting not just to net zero but to our objectives under carbon budget 5, gets potentially further away, rather than closer.

The good news is that there is a better way. In recent years, the technology and supply of renewable liquid fuels have developed. If we were to use renewable liquid fuels such as hydrotreated vegetable oil, there is a great opportunity for us to get an 88% reduction in our carbon emissions, but far faster than the current Government strategy. It could get us an 88% reduction by carbon budget 5 simply by having an adaptation of those existing boilers.

A pilot in my own constituency has been testing hydrotreated vegetable oil. Residents who have used it report that it burns more efficiently. Some say that the use of the fuel is around 30% lower than with kerosene. The people at the church hall like it because they need intermittent heat, and they can switch it on without having a heat pump running continuously, wasting all that energy. The staff at the school like it because it works for their Victorian building. There is a huge amount to be said for opening the door to the deployment of these renewable liquid fuels. The Government already recognise this, because the renewable transport fuel obligation, introduced in 2007, creates an incentive scheme to require both importers and refiners of fuel to source some of that from renewable sources, such as hydrotreated vegetable oil. The Bill is an opportunity to extend the architecture of the RTFO, a long-standing scheme, to domestic boilers as well so that we can have that incentive.

I know that some officials in the Department argue that we cannot be certain that hydrotreated vegetable oil comes from renewable sources. I do not accept that. There is a British standard—an accreditation scheme for HVO that comes from renewable sources. It would be very easy for the Government, through regulation, to insist that only British standard-certified HVO would be allowed for this purpose. The officials have also raised questions about the supply of renewable HVO, but we are seeing an exponential rise in supply both from the United States and from the European Union and the potential to develop it in this country as well.

I very much hope that the Government will look favourably on amending the Bill—clause 104 of part 3 of the Bill would be key—preferably with their own amendment to give respite to 1.7 million homes in rural locations. If not, I shall seek, if I have the support of the House, to amend the Bill. My private Member’s Bill attracted huge support not just from Conservative Members, but from Members across the House, and the Government should consider it.
