My Lords, these regulations were laid in draft before the House on 30 October 2024. The Government believe that the answer to the challenges around energy security, affordability and sustainability point not in different directions but in the same direction: clean power. Investing in clean power at speed and scale can help tackle the climate crisis and create good jobs. We believe that it is the only route to protect bill payers and ensure energy security; this is why making Britain a clean energy superpower by 2030 is one of the five central missions of this Government.
To deliver that mission, we will rely increasingly on a renewables-led system as the foundation for a decarbonised grid. We have set ambitious but deliverable targets to double onshore wind, treble solar and quadruple offshore wind by 2030. Although renewable energy is at the heart of our plan to deliver clean power, we also know that we must bring forward low-carbon generation sources, providing added security for when the sun does not shine and the wind does not blow. This includes flexible supply sources that can scale up or down instantaneously to meet peak demand.
Some of this flexibility can be provided by short-duration technologies such as batteries, which can help balance the system within each day, but we know that we will also need long-duration technologies, which can run for extended periods of low renewable production. To meet this challenge, the Government are investing in low-carbon flexible technologies, such as carbon capture and storage at existing power stations, hydrogen and long-duration electricity storage. This flexibility is critical to maintaining a constant supply of electricity in the UK, keeping the lights on for millions of homes and businesses.
However, as these new low-carbon technologies scale up, we will continue to need reliable mature technologies, including gas, to provide energy security. The National Energy System Operator’s report on delivering clean power by 2030 showed that maintaining gas capacity in the system is in line with the mission to deliver clean power. We have been clear from the outset that gas is expected to be used less in our future energy system, moving to an important strategic reserve role in order to ensure security of supply. Although gas will continue to play an important role in the system, it is only right that we should expect any new or substantially refurbished combustion plants to be built “net zero-ready”. This is why we are uplifting the existing regime and introducing the new decarbonisation readiness requirements.
Before I turn to detail of the decarbonisation readiness requirements, let me first set out the current regime. Since 2009, all new-build combustion power plants in Great Britain sized over 300 megawatts have been subject to the carbon capture readiness requirements. These regulations require plant operators to demonstrate that it is technically and economically feasible to retrofit carbon capture and storage technology. Due to the threshold of 300 megawatts, the policy has seen limited application since 2009. The reality is that it has contributed to a costly market distortion by incentivising the building of smaller, less efficient plants and inadvertently creating an unacceptable loophole. This has resulted in a significant number of plants being built at 299 megawatts in order to avoid the carbon capture readiness requirements.
The policy landscape has changed significantly since the carbon capture readiness requirements were introduced. Plant operators now have an alternative pathway to decarbonise, through hydrogen-fired generation, as well as the introduction of the UK’s legal obligation to meet carbon budgets and reach net zero by 2050. In March 2023, a final consultation on the decarbonisation readiness proposals was published alongside the publication of two technical studies for hydrogen and carbon capture and storage. The consultation received positive feedback from industry. Some 28 organisations and one individual responded—representing plant operators, original equipment manufacturers and trade associations—with broad support for the proposed changes and implementation of the decarbonisation readiness requirements. We published a response in mid-October, giving the go-ahead to proposals set out in the consultation.
On the details of the regulations, this statutory instrument will amend the Environmental Permitting (England and Wales) Regulations 2016 by inserting new Schedule 25C. It will remove the minimum capacity threshold of 300 megawatts, which will remove any existing market distortion and support rapid decarbonisation by ensuring that nearly all new and substantially refurbishing combustion power plants must have a credible plan to decarbonise. The regulations will also move the requirements from the planning consent process, where they currently sit for carbon capture readiness, to environmental permitting. This will ensure that the responsibility for regulating the requirements falls to the Environment Agency rather than to local planning authorities and my own department. Unlike local planning authorities, the Environment Agency is already involved in the assessment of carbon capture readiness and has the technical expertise to assess the requirements. As I mentioned a moment ago, that will also include hydrogen readiness.
The new requirements will now enable combustion plants to demonstrate decarbonisation readiness through conversion to hydrogen firing, as well as carbon capture. In doing so, the instrument introduces hydrogen conversion readiness and carbon capture readiness assessments, which are proportionate to the developing nature of hydrogen to power and carbon capture and storage. The requirements will also expand the generation technologies in scope of the requirements to include biomass, energy from waste and combined heat and power plants. This will ensure that a higher number of carbon-intensive plants are now captured.
These updated requirements are intended to strike a balance. They ensure that new-build plants and the refurbishment of old sites are conducted ready to take full advantage of future decarbonisation opportunities, while acknowledging the emerging state of hydrogen and carbon capture technologies and their enabling infrastructure. We expect that the requirements will be strengthened over time as the generation technology improves and clarity on enabling infrastructure availability increases. To ensure that we regularly assess the impact of the policy and the case for strengthening the requirements, we have included a statutory requirement for the Government to carry out a review of the policy in periods not exceeding five years.
In summary, these regulations will ensure that the gas capacity we need for security of supply is future-proofed and has a credible plan to transition to low-carbon operation. In doing so, it will help deliver our aim to become a clean energy superpower and deliver net zero by 2050. I beg to move.
