I recognise that some potential long-duration storage solutions are innovative technologies, but pumped hydro storage is not: it is old and proven, in terms of both effectiveness and value over the long term. These amendments will not solve things, but we may come back more specifically on Report. What I want to get from the Government is some understanding of whether they feel they can come forward with at least a pathfinder solution, possibly for something like Coire Glas, because that will take a long time to build out. It needs to get going and the people developing it cannot just keep these things mothballed all the time; they need to know the revenue support model. I hope the Government will respond specifically on that issue. I also hope they will think about how to separate their support models for innovative technologies, which may need to be more flexible or different, from those for proven technology that we can get on with now. I beg to move.

My Lords, I have some sympathy with what the noble Lord, Lord Oates, has just said. My concern is perhaps even a little more profound than his because I do not understand what role the Government see for pumped storage in addressing the problem of intermittency of renewables. The noble Lord focused on the funding mechanism, but what role is it going to have? How large a part do the Government intend that it should play?

However, that is not my purpose in rising. My purpose is to speak to Amendment 225, which relates rather to gas, which is also there to be used to some extent to address the problem of intermittency. I am grateful for the support of the noble Lord, Lord West of Spithead, and my noble friends Lady McIntosh of Pickering and Lord Frost. The House had a Question on gas storage earlier today and the Minister made some helpful and informative comments in response, but it was largely a backwards-looking Question. It looked at decisions taken in the past, whereas this amendment is intended to look a little more forward. It would require the Government to provide gas storage onshore or under our waters equivalent to 25% of forecast annual demand. However, in a sense, the real purpose is to give the Government an opportunity and to elicit from them some sense of their plans for addressing this question. In the past few months, we have all seen on the television news and in the newspapers, and been gripped by it, that while Germany has been busily filling up its capacious gas storage facilities, we have none whatever, so I think the Committee and the public will be interested to know what the Government intend, if the Minister is capable of giving us an indication today.

I shall make just two points about the amendment. To those who say that we are phasing gas out, I say that the amendment is worded to require 25% of forecast demand, so if the demand comes down, the amendment still works and the amount stored can be adjusted. I think I am a correct in saying—this emerged at Second Reading—that nobody in the House believes that demand for gas is going to fall to zero, even if it is to fall to quite low or even miniscule levels, so the amendment still works and, planning over the long term and looking forward a number of years, it should be possible to make this workable.

Secondly, I put in 25% as a placeholder as much as anything else. I am very open to the Government making a case for why that number should be higher or lower and why government policy should not be 25% but more or less. I am even open to an argument that the number should be 0%. Indeed, reviewing what the Minister said today, he made the valid point that, unlike Germany, we already have a store, so to speak, of gas in our control; it just happens to be under the sea. I understand that there is a point there.

I think back to the United States in the 1970s, when the oil shock arrived. The United States decided that what it needed was a large oil reserve, so it started pumping oil into specially prepared caverns in the earth. Then I think it struck the US that it was pumping oil out of one bit of the earth and then pumping it into another, and that perhaps this was not as sensible as it might have been, so the policy was gradually abandoned.

The Minister may want to make a similar and parallel point in respect of our own gas reserves. He may say that zero is a perfectly reasonable amount for us to store. If the answer from the Government were zero, it would at least be a decision and a policy. We would be able to scrutinise it and understand the arguments for it. As I say, setting the number at 25 is very much a placeholder. I am not being in any sense dogmatic about what the number should be, but I do feel that the Government should have a number in mind, should be able to justify it—even if it is zero—and should be able, I hope, to tell us what it is.

My Lords, I fully support the amendments in the name of my noble friend Lord Oates and that in the name of the noble Lord, Lord Moylan, and others. They seek, in effect, to get more information from the Government about their plans in relation to energy storage.

My Amendment 240 is also about storage but, in this case, the storage of solar energy, the use of which is growing at an incredibly rapid pace. There are already something like a million domestic solar systems installed around the UK, and residential solar deployment is at a record subsidy-free level according to Solar Energy UK, which represents many of the UK’s solar firms. This is perhaps unsurprising given the benefits of generating your own electricity at home. This is also good news for the Government since, if we are to meet our net-zero target by 2050, we need as many of the 29 million homes in UK as possible to decarbonise. Solar is of course part of that solution.

At this point I should draw attention to my interests. I recently installed solar panels on the roof of my home, together with one battery; it is the battery element that is relevant to my amendment. It was great news when, in the Spring Statement delivered on 23 March, the then Chancellor, Rishi Sunak, made the very welcome announcement that certain energy-saving materials would be eligible for zero-rate VAT on both labour and parts. This change was effected through the Value Added Tax (Installation of Energy-Saving Materials) Order 2022, which added a list of energy-saving products eligible for the zero rate to Schedule 8 to the Value Added Tax Act 1994, which is relevant, as noble Lords will see in a second.

Solar panels are the only solar-related items specifically included in this list. Batteries that store the energy from solar panels when it is not needed, and which can be used at a time when it is needed or to supply energy back to the grid, are not listed. However, the energy-saving materials and heating equipment VAT notice 708/6, which relates to the earlier Act, states:

“The installation of certain specified energy-saving materials with ancillary supplies is zero-rated in Great Britain.”


I can find no reference to “ancillary supplies” in the Value Added Tax Act 1994, which the Chancellor’s Spring Statement amended. However, HMRC has said that, in certain circumstances, batteries are in fact included. It has said that, when batteries are sold as part of the installation of a solar array, they are to be treated as an ancillary supply and so also qualify for zero-rate VAT. However—this is the crucial point—they would not qualify if installed separately at a later date.

A neighbour of mine, Mr Geoff Makepeace, installed a solar array with batteries a while ago; it was before the Spring Statement, so he did not benefit from the zero rate of VAT announced in it. However, keen to get increased benefit from his solar system, he sought advice: should he increase the number of solar panels or the number of batteries? The advice was to install another battery. He followed that advice but was subsequently surprised that his bill included £567 for VAT at 20%.
