The Humber H2ub (Green) project in the UK has been unveiled with plans to submit a full application for development consent in 2025. The project, targeting the Humber area, aims to establish an initial electrolytic hydrogen production capacity of up to 120MW, with potential for further expansion to 200MW. This initiative is part of the UK government's support for creating new industrial hubs, with the hydrogen produced intended to supply the nearby Humber Refinery. The goal is to replace some refinery fuel gas with green hydrogen by 2029, contributing to the reduction of scope 1 operational emissions. The project anticipates the use of 45t per day of green hydrogen, equivalent to 100MW electrical capacity. The source of electricity for the project remains unspecified, with options including on-site development or low-carbon power generation. The project's electricity supply could be facilitated through power purchase agreements and renewable guarantees of origin. Overall, this initiative reflects a positive step towards industrial decarbonization and aligns with efforts to transition towards sustainable energy solutions in the UK.
