Consultation on modernising environmental permitting for industry

Closes 21 Oct 2025

Hydrogen production 

In the IED 2.0 the EU have raised the threshold for permitting of hydrogen production via the electrolysis of water to 50 tonnes per day. The EA is already using mechanisms including GET and standard rules to expedite and streamline permitting but given the importance of this technology and the relatively low environmental risks associated with the sector, we would like to explore the case for going further in streamlining regulation. 

This could be achieved by setting a new threshold for permitting of hydrogen in Schedule 1 of the EPRs (for example at 50 tonnes per day as in the EU) which would remove the need for sites below the thresholds to obtain an installation permit. Alternatively, we could consider a registration approach (as outlined in the previous section) for smaller-scale electrolysis to reduce cost and approval timelines, while maintaining some degree of regulatory oversight.  

27. Do you have any comments on the most proportionate approach to permitting of hydrogen production via the electrolysis of water? Please outline your views on any potential costs or benefits the proposal may bring to you and/or your organisation, as well as any positive or negative impacts it could have on human health or the environment.
