Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, pursuant to the Answers of 12 March 2025 Questions (a) 35320 and (b) 35322 on Alternative Fuels: Ammonia, whether he has considered domestic ammonia storage for on-demand ammonia cracking and deployment, in the context of (i) his Department’s assessment of the potential role of low carbon ammonia in a diversified energy mix and (ii) UK energy security.

Ammonia cracking is a nascent technology that the Government has previously supported through the Net Zero Innovation Portfolio. As set out in the Market Engagement document, the early focus of the Hydrogen Storage Business Model will be geological storage. The use of ammonia as a form of chemical storage for cracking to hydrogen was assessed to have low technology readiness. Government continues to review technological developments and may make changes to HSBM eligibility when appropriate to do so.
