Opened 14 Dec 2023


To be able to make an application to the Second Hydrogen Allocation Round (HAR2), the Project Representative must submit an Expression of Interest (EoI) to DESNZ on behalf of their Project by 23:59 on 5th February 2024. Submitting an EoI by this date will allow projects access to the Online Application Form and the final engagement session. 

Submission of this Expression of Interest form is a necessary condition to participate in the process.  

Projects should use this form in order to identify themselves to DESNZ, confirm they meet all of the eligibility requirements as well as provide some basic information relating to their project, and select a Project Representative who will be provided access to the Online Application Form. Further information on the role of the Project Representative can be found in Section 2.2 of the Application Guidance. EoI answers are considered as indicative only and not as firm responses.

Please note that all information in this form should relate to the Project only. The Project Lead must be the business/entity which is leading the project development and will manage the application process.

Although under no obligation to do so, DESNZ reserves the right to process EoIs received after the above deadline at its absolute discretion.
