Uniper’s Humber H2ub (Green) Wins Planning Permission To Build 120 MWe Electrolytic Hydrogen Plant In Killingholme

Planning permission has been granted by North Lincolnshire Council for a new low-carbon hydrogen production facility to be developed in Killingholme. The project, known as Uniper’s Humber H2ub (Green), will be built on land at Uniper’s existing Killingholme power station site. Once operational, the electrolytic hydrogen facility will have an installed capacity of 120 MWe, with plans for a potential future expansion of more than 200 MWe.

Uniper submitted the planning application to the council in October of last year following an extensive public consultation programme. After reviewing the proposal and community feedback, the council approved the application on 20 March. The project has also been shortlisted under the UK Government’s Hydrogen Allocation Round 2 (HAR2) programme, which aims to support the development of low-carbon hydrogen projects across the country.

Securing planning approval marks a major milestone for the Humber H2ub (Green) project and represents an important step toward establishing large-scale low-carbon hydrogen production in the Humber region. Uniper has expressed appreciation to North Lincolnshire Council and to all individuals and organisations who provided input during the consultation process, noting that continued stakeholder engagement will remain an important part of the project’s progress.

Once the facility begins operations, the hydrogen produced—meeting the government’s Low Carbon Hydrogen Standard—will be supplied to Phillips 66 Limited’s Humber Refinery starting in 2029. This supply will support the refinery’s wider efforts to reduce its Scope 1 emissions and transition to lower-carbon operations. The project therefore not only contributes to regional decarbonisation goals but also supports the UK’s broader hydrogen strategy by enabling industrial users to access cleaner fuel sources.

Additional information about the development and its ongoing progress can be found through the Humber H2ub (Green) project’s official channels. The approval of this facility positions Killingholme and the wider Humber area as key contributors to the UK’s emerging low-carbon hydrogen economy.
