My Lords, the amendments from the noble Lord, Lord Oates, are very welcome and they plug a gap in the Energy Bill. Amendment 50 facilitates the changes proposed by allowing the Secretary of State to
“designate the person to be a counterparty for long duration energy storage revenue support contracts.”
Amendment 51 introduces a new clause which allows the Secretary of State to
“direct a long duration energy storage counterparty to offer to contract with an eligible person”.
Clauses 59, 61 and 63 already allow designation of counterparties for transport and storage, hydrogen production and carbon capture revenue support contracts, and Amendment 50 simply replicates this for long duration energy storage. Similarly, Clauses 60, 62 and 64 already allow the Secretary of State to direct counterparties to offer to contract, and Amendment 51 replicates this for long duration energy storage.
The amendments define long-duration energy storage revenue support contracts as being
“between a long duration energy storage counterparty and the holder of a licence under section 7”
and, as ones
“entered into by a long duration energy storage counterparty in pursuance of a direction given to it under section 60(1).”
This fills a big gap for long-duration energy storage. According to the Government, longer-duration storage—access across days, weeks and months—could help to reduce the cost of meeting net zero by storing excess low-carbon generation for longer periods of time, thereby helping to manage variation in generation, such as extended periods of low wind. This in turn could reduce the amount of fossil-fuel and low-carbon generation that would otherwise be needed to optimise the energy output from renewables.
Long-duration energy storage includes pumped storage as well as a range of innovative new technologies that can store electricity for four hours to supply firm, flexible and fast energy that is valuable for managing high-renewables systems. Introducing long-duration energy storage in large quantities in Britain by 2035 can reduce carbon emissions by 10 megatonnes of CO2 per annum, reduce systems costs by £1.13 billion
per annum and reduce reliance on gas by 50 TWh per annum. That seems to me worth consideration in this Bill.
Amendment 225 in the name of the noble Lord, Lord Moylan, which has general support around the House, requires the Government to produce a strategy for the storage of gas for domestic consumption. This would see the construction and operation of gas storage facilities capable of holding 25%, although it could be more—it could be 100%—of forecast domestic consumption each year beyond 2025. While agreeing that UK gas storage is currently small, which may have left us exposed to higher prices and shortages thus far, is it the solution to the long-term energy supply problems that we may face? It may well be that we need an immediate expansion of gas, but whether it is the long-term solution to our energy supply is open to some question. The UK currently stores enough gas to meet demand over four or five winter days, which is clearly not enough. But the new Chancellor said, when he was the Business Secretary, that the answer to mitigating a quadrupling of the gas price in four months was to get more diverse sources of supply, and more diverse sources of electricity, through non-carbon sources. So there is some doubt about the long-term viability of increasing gas storage.
Amendment 240 from the noble Lord, Lord Foster, would establish a new clause to store energy generated by solar panels in the list of energy-saving materials that are subject to zero-rate VAT. He had the example of his friend in the south-west. Modelling from Cornwall Insight’s view of the GB power market out to 2030 has shown that between 2025 and 2030 the Government must spend almost one-fifth of their total energy technologies investment, which includes solar, wind, nuclear and carbon capture and storage, on energy storage batteries, if we are to meet renewable targets and stabilise the energy market. Latest data estimates that almost 10% of grid capacity will be provided by battery storage by 2030, at an estimated cost of £20 billion. So, considering both the need and the cost of this, the amendment seems a sensible proposal to encourage the market to take up some of the burden.
