Details

The Hydrogen Allocation Rounds (HARs) are a government funding mechanism to support low carbon hydrogen production across the UK.

These reports provide learnings on the different processes and outcomes of the pre- and post-shortlisting stages of the Hydrogen Allocation Round 1 (HAR1), up to the announcement of successful projects. They inform our thinking for the design and delivery of future allocation rounds.

The Post-shortlisting process evaluation (published April 2025) covers:

• Request for Information (RFI) stage
• due diligence stage
• negotiation stage

38 participants were interviewed, including:

• HMG officials
• successful shortlisted projects
• unsuccessful shortlisted projects
• technical / commercial advisors

The Pre-shortlisting process evaluation (published December 2023) covers:

• design
• application
• communication
• future considerations

38 participants were interviewed, including:

• applicants
• non-applicants who submitted an EOI
• non-applicants who did not submit an EOI
• DESNZ staff and technical advisor

The Department commissioned the Technopolis Group to carry out both process evaluations.
