Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government when they expect the neighbourhood trial, referred to in the impact assessment on the Hydrogen Heating Village Grid Conversion, published on 6 July 2022, to (1) commence, (2) conclude, and (3) report; and what measures they will use to evaluate its success.

The neighbourhood trial is SGN’s H100 Fife project in Levenmouth. SGN plans to deliver hydrogen to consumers in mid-2024 and conclude by 2027. SGN provides evidence and regular progress updates to the Department for Energy Security and Net Zero, Ofgem and the Health and Safety Executive. They also produce an annual report in accordance with conditions set by Ofgem, who part funds the project

H100’s evidence is already shaping plans for the village trial, including on costs and regulatory challenges. Alongside evidence from the village trial, H100 will inform the Government’s strategic decisions in 2026 on the role of hydrogen in decarbonising heat.
