Progress ranking and key recommendations

Progress Ranking: Good (6/10)

Key actions on the road to world-leading policy

  • The Government published the Hydrogen Strategy in August 2021, which sets a strong policy direction towards CCC expectations. The Strategy highlights the Government’s support for hydrogen development in the next decade and its role in reducing emissions.
  • The Government released the Energy White Paper in December 2020, which provided detail on the Government's strategy for power sector decarbonisation. The Government has also committed to holding the next contract-for-difference auction in late 2021, which will be open to onshore wind and solar.
  • Out of fifteen recommendations we can currently assess that the CCC has made for the power sector, eight have been met in full already, with two partially met, and three not met.
  1. The Government should commit to a phase-out of unabated gas generation by 2035, and provide a detailed pathway for this by the end of 2021, covering:

    1. Alternatives for unabated gas in dispatchable generation
    2. Right incentives to push unabated gas down the merit order
    3. Ensuring that all new-build gas by 2025 at the latest is CCS and/or hydrogen-ready.
  2. The Government should also set a carbon intensity target for the power sector for 2030 of ~50gCO2/kWh to provide long-term confidence around the pace of power sector decarbonisation

  3. In the next Contracts for Difference (CfD) auction in 2021, Government should ensure that advanced conversion technologies are moved to Pot 1 rather than Pot 2. This covers anaerobic digestion (above 5MW) and dedicated biomass CHPs.

Sector Summary

  • Power sector emissions in 2019 were 52MtCO2e, or 10% of the UK total (CCC Progress Report, 2021)
  • Emissions fell 13% from 2018-19 (CCC Sixth Carbon Budget, 2020). From 2019-2020 emissions fell 15%.
  • Major emission reductions will come from offshore wind, other renewables (onshore wind and solar), potentially nuclear, and dispatchable low-carbon generation.
  • Current government ambition and policy is in line with net zero for one of these areas (offshore wind), but risks falling behind on all other areas (other renewables, nuclear and dispatchable low-carbon generation)

Recent Policy Developments

  • In August 2021, the Hydrogen Strategy was published, setting out the steps needed in this decade to create a low carbon hydrogen economy. The Strategy commits to a 'twin track' approach to hydrogen production, supporting both electrolytic, known as green hydrogen, and carbon carbon and storage enabled hydrogen, known as blue hydrogen.
  • The power sector has seen the fastest emission reductions of all UK sectors, driven by coherent and consistent policy that has driven innovation and reduced fossil fuel usage. The key policies that have driven success over the last decade have included long-term contracts for renewable electricity via the contracts for difference projects, carbon pricing via the EU-ETS and UK Carbon Price Support, clear phase-out dates for coal generation, energy efficiency policies to reduce demand, and the creation of a capacity market to ensure sufficient security of supply.
  • Ofgem announced that network operators will have to demonstrate how their business models are compatible with Net-Zero
  • In March 2020, the Government announced that onshore wind and solar PV would be able to access the next round of Contracts for Difference (CfD) auctions, reversing a four-year ban on their inclusion.
  • In December 2020, the UK's Energy White Paper was published. In this, the Government committed to:
    • Installing 40GW of offshore wind by 2030, including 1GW of offshore floating wind
    • Holding the next Contracts for Difference auction in late 2021.
    • Having at least one power plant with CCUS operating by 2030 and consulting on plans to ensure existing and new gas-fired power plants can convert to low-carbon alternatives, with a consultation date of early 2021.
    • The White Paper also had a significant focus on nuclear, aiming to bring at least one large-scale nuclear project to final investment decision by the end of the current Parliament, and providing £385m funding for advanced nuclear technologies such as SMRs and AMRs. 
  • Other commitments in the Energy White Paper included an aim for a commercially viable fusion plant by 2040, establishing the role that BECCS can play in emissions reduction via a cross-Government bioenergy strategy due in 2022, and completing a review of the existing National Policy Statements for energy, with the aim of designating these updated NPS' by the end of 2021

Policy Recommendation from the CCC

Government Progress



Publish a plan for reaching an emissions intensity of 50 gCO2/kWh by 2030, with a total of around 350 TWh of new low-carbon generation by 2035. Set out a schedule for regular auctions to procure low-carbon generation, with a clear pathway of volumes to be procured and robust contingency for uncertainties in demand and delivery. Address potential barriers to deploying and using low-carbon generation at scale (e.g. the planning and consenting regime for renewables and networks, exposure to climate risks) and, with Ofgem, develop a framework under which sufficient supply resilience can be ensured.

The Energy White Paper has some good policy announcements here – committing to 40GW of offshore wind, and acknowledging that wind and solar will form the backbone of a low-carbon electricity system. Opening Contracts for Difference (CfD) auctions to onshore wind and solar again, and holding another auction in late 2021 will also help drive large-scale low-carbon electricity deployment. However, there is no specific focus on how this gap in future low-carbon electricity supply will be provided.



Phasing out unabated gas generation. The Government should commit to a phase-out by 2035.

There has as yet been no commitment to phaseout unabated gas generation by 2035.



Phasing out unabated gas generation. The Government should follow this commitment up with a detailed plan, covering:
a) Alternatives for unabated gas in dispatchable generation
b) Right incentives to push unabated gas down the merit order
c) Ensuring that all new-build gas by 2025 at the latest is CCS and/or hydrogen-ready.

The Energy White Paper makes limited progress here. For example, some of the £1bn Net Zero Innovation Portfolio will go to hydrogen and advanced CCUS, which would be the likely dispatchable options to replace unabated gas.

However, there is no mention in the Energy White paper or anywhere else about market incentives to push unabated gas down the merit order. (item b in the phaseout plan). There is no firm commitment on a phaseout date for unabated gas, with the Paper instead focusing on ‘likely eliminating the reliance on generation from unabated gas’, and intending to consult in early 2021 over proposals to update carbon-capture readiness requirements, to include hydrogen-readiness as an option and remove 300MW threshold (which is currently providing a perverse incentive for 299MW fossil power plants).

Greater clarity around the future for unabated gas generation could also come via the review of the energy National Policy Statements, which the Energy White Paper commits to in 2021.

The Government's Hydrogen Strategy states a consultation will be released later in 2021 on the case for enabling, or requiring, new natural gas boilers to be easily convertible to use hydrogen (‘hydrogen-ready’) by 2026.



Market design for net-zero. We will need to reform electricity markets to be fit for a world with high proportion of renewables. This includes:
1. Need for certain and predictable signals
2. Need for a whole-market approach – reflecting importance of supply and demand side solutions
3. Need to ensure security of supply and markets for dispatchable capacity.

In the Energy White Paper, a key commitments is around Efficient Electricity Markets. They commit to publishing a new Smart Systems Plan in 2021 with Ofgem, and to define electricity storage in law.

The White Paper commits to £100m of funding for longer duration energy storage, and to working towards ‘a market framework which ensures that national and local electricity markets are fully coordinated’ (which would be beneficial for flexibility in the electricity market). The next review of the capacity market is still in 2024 – this may need to be brought forwards as part of the electricity market reform.

The Energy White Paper acknowledges that ‘current market framework emphasises the cost of fuels… but renewable technologies, such as wind, do not use fuel at all. It is also poor at valuing some services which will become increasingly important to the system, such as local balancing.’



At least 40GW of offshore wind by 2030

The Ten Point Plan/Energy White Paper both commit to this target.



Continue to improve system flexibility via implementing all the actions in the Smart Systems and Flexibility Plan, including working with the Department for Digital, Culture, Media and Sport on cyber security. Develop mechanisms that encourage consumers to be flexible.

The Government has implemented two-thirds of the actions in the Smart Systems and Flexibility Plan, released in 2017, and is on track to deliver these actions in full by 2022.

Alongside this, the Government will publish a new Smart Systems Plan in Spring 2021 jointly with Ofgem, which will set out how the Government aims to build on the Smart Systems and Flexibility Plan.



Develop a strategy to coordinate interconnectors and offshore wind farm network connection to onshore grid, and bring forward any necessary legislation.

BEIS launched a consultation on this topic in July 2020, and so should be on track to publish a strategy by the end of 2021, as asked for by the CCC.



Consult on future electricity market design as renewables makes up a bigger share of generation

Alongside the Energy White Paper, the Government published a consultation on how best to support a High Renewable, Net Zero Electricity System. This seeks view on ‘how the contracts-for-difference scheme could evolve beyond the 2021 auction, including how longer-term changes to the contracts-for-difference or wider electricity market design can enable the effective integration of increasing renewables capacity’



Move Advanced Conversion Technologies (ACT), Dedicated Biomass-CHP and large-scale Anaerobic Digestion to the CfD Pot 1 for established technologies (so that other technologies can compete for the Pot2 money such as floating offshore wind). Restrict ACT to combined heat and power applications only, where the emissions benefit is greatest.

Advanced conversion technologies, anaerobic digestion (above 5MW), dedicated biomass with CHP are still in Pot 2 (advanced technologies) rather than Pot 1. This means they are competing with other technologies which should arguably take priority, such as floating offshore wind. 


10 Develop mechanisms for strategic investment in coordination with Ofgem to ensure that electricity networks can accommodate increased future demand levels, including large localised demand increases associated with electrification in manufacturing, transport and buildings, and that lack of network capacity does not cause delays in emissions reduction The CCC has recommended that this is achieved by 2023. N/A
11 Work in partnership with Ofgem to publish and implement a new Smart System Plan and Energy Data and Digitalisation Strategy, including working with DCMS on cyber-security, in order to continue to unlock the full benefits of electricity system flexibility. Ensure that, alongside smart standards for heating, all electricity users have access to half-hourly metering and the option of tariffs that encourage flexibility in use of electric heat and electric vehicle charging. The CCC has recommended that this is achieved by the end of 2021. N/A
12 There must be financial and market incentives under a policy framework to boost the uptake of hydrogen. There must be incentives for early use of hydrogen; avoiding perverse incentives in the production of hydrogen; and creating a decarbonisation level playing field so that incentives for hydrogen use are designed so that bias is not introduced towards hydrogen solutions where electrification is not competitive

The Hydrogen Strategy proposed several commitments to creating a market for hydrogen, including market framework and regulatory framework, these include:

- Publish a consultation response to the Hydrogen Business Model in Q1 2022, with the aim to finalise the business model in 2022, enabling the first contracts to be allocated from Q1 2023.

- Undertake further work to understand and develop appropriate market frameworks to drive investment and deployment and transition to longer term competitive market frameworks, aiming to publish initial conclusions and proposals in early 2022.

- Work across government to highlight the potential role of hydrogen in the future energy system and consider whether and how this should be reflected in wider regulatory and policy changes.


The Hydrogen Strategy should focus hydrogen demand on areas where that cannot feasibly decarbonise without it

The Hydrogen Strategy refers to hydrogen's potential to support the deep decarbonisation of the UK economy, particularly in ‘hard to electrify’ UK industrial sectors, and can provide greener, flexible energy across power, heat and transport. This signals a focus for hydrogen in hard to debate areas of key demand Yes
14 The Hydrogen Strategy should set out an intention to pursue proven solutions (e.g. electrification) in the 2020s, in parallel with developing hydrogen The Hydrogen Strategy states low carbon hydrogen will play an important complementary and enabling role alongside clean electricity in decarbonising the energy system. It notes that hydrogen is suited to use in a number of sectors where electrification is not feasible or is too costly, and other decarbonisation options are limited. This signals a parallel approach that pursues electrification as well as hydrogen development. Yes
15 In its Hydrogen Strategy, the Government should set out its vision for the respective balance between hydrogen produced from electrolysis and from CCS out to 2035. The CCC call for a ‘blue hydrogen bridge’ approach, which would entail supplementing electrolysis with scalable production from routes involving carbon capture and storage (CCS) to enable sufficient low-carbon hydrogen production to meet a fuller range of emerging demands. This approach will both reduce emissions more quickly in the near-term as well as develop the role of hydrogen across a range of sectors. The Hydrogen Strategy is clear that to meet the Government's ambition for 5GW of low carbon hydrogen production capacity by 2030, the Government will commit to a ‘twin track’ approach to hydrogen production, supporting both electrolytic and CCUS-enabled hydrogen. The Government will provide further detail on their production strategy and twin track approach by early 2022. Partly
