Hydrogen can undoubtedly help key UK industrial sectors decarbonise.
Recommendation
Hydrogen can undoubtedly help key UK industrial sectors decarbonise. There is a widespread recognition of the importance of regulatory reform and an effective business model in incentivising a switch to low-carbon hydrogen use. We welcome the Government’s use of industrial …

Recommendation
Hydrogen has a modest but potentially critical role to play in decarbonising the rail network, where electrification is not suitable or cannot be delivered in time to contribute towards meeting Net Zero. Whilst trials and demonstration projects are underway in …

Conclusion
Acknowledged
Hydrogen has several distinctive features as a low-carbon gaseous fuel and could contribute to the UK’s energy system, including through improving resilience and energy security. Whilst in some applications hydrogen is less efficient compared to alternative low-carbon technologies, the wider energy system benefits of deploying hydrogen must be acknowledged, and …
Government Response Summary
The government acknowledges that system level thinking has been a key element of its approach to developing hydrogen in the UK, and that the potential impacts on system resilience and energy security are reflected in the increased ambition brought forward under the British Energy Security Strategy.

Conclusion
Acknowledged
Para 44
The Government has chosen at this stage to support the development of both green and blue hydrogen. We heard that the initial adoption of blue hydrogen will be cheaper than green hydrogen, and ready to use in certain niche industrial settings sooner. However, several analysts have argued that green hydrogen …
Government Response Summary
Government has been clear in the UK Hydrogen Strategy and subsequent publications that it considers support for multiple production routes the most appropriate approach while building the hydrogen economy.
17
Conclusion
Acknowledged
Para 133
Hydrogen could play a role in domestic heating, but the extent of its potential is still uncertain and looks likely to be limited rather than widespread. We are unconvinced its deployment will prove to be economically viable by the time the Government has said it will determine the role of …
Government Response Summary
Government is proposing to require that from 2026 all newly installed domestic-scale natural gas boilers be hydrogen-ready, and is awaiting a response to the consultation on boiler standards before publishing its updated thinking.

Conclusion
Acknowledged
Para 145
Metering is an essential component of any use case for hydrogen in domestic settings. We have heard that the current generation of gas smart meters are designed to measure volume flows of natural gas which are much lower than hydrogen volume flows for the same energy delivery, so are unlikely …
Government Response Summary
The government acknowledges the need for meter accuracy, especially distinguishing between hydrogen blends and 100% hydrogen, and states that the OPSS and suppliers are working to ensure meter accuracy.
21
Conclusion
Acknowledged
An urgent project on metering domestic hydrogen use needs to be undertaken. This should include an assessment of: • whether and when the current generation of gas smart meters need to be (a) adapted, or (b) replaced; • what technology could and should be used in new meters to accommodate …
Government Response Summary
The government acknowledges that current smart meters could work on a 20-23% hydrogen blend, with ongoing assessment by the OPSS. They mention the Hy4Heat program and hydrogen heating trials that will inform strategic decisions in 2026.

Conclusion
Acknowledged
Para 184
There appear to be opportunities and advantages in the UK accelerating its decarbonisation of the economy by focusing on hydrogen and becoming a leader in low- carbon hydrogen production, distribution, and deployment for multiple purposes. But, as discussed in this Report there are still uncertainties which entail the risk that …
Government Response Summary
The government states that the Sector Development Action Plan (SDAP) sets out actions to maximize the benefits to the UK from the development of the hydrogen economy, focusing on attracting investment, supporting supply chains, developing skills, and securing trade opportunities.
27
Conclusion
Acknowledged
As with other low-carbon systems, there are costs associated with the development of infrastructure and the uptake of hydrogen use within every use case. The relatively higher prospective cost of low-carbon hydrogen will increase overall costs of, for example, manufacturing, transportation, or heating. There is a risk that because of …
Government Response Summary
The government acknowledged the risk of non-competitiveness due to the higher costs of low-carbon hydrogen and outlined measures such as the Hydrogen Production Business Model (HPBM), transport and storage infrastructure, and exploring the need for market intervention on hydrogen power.
