Plug Power shares were up over 2% in pre-market trading on Wednesday after the company announced that the 30-megawatt (MW) Barrow Green Hydrogen project in Barrow-in-Furness, Cumbria (UK), where Plug is supplying electrolyzers, has reached final investment decision (FID).

The Barrow Green Hydrogen project is being delivered by Green Hydrogen Energy Company, a joint venture established in 2023 by Schroders Greencoat and Carlton Power. Under the finalized agreement, Plug Power will supply 30 MW of its GenEco Proton Exchange Membrane electrolyzers to the facility.

The Barrow project will feature six 5 MW Plug GenEco PEM electrolyzers, using renewable electricity to produce green hydrogen. The project was originally announced as part of Plug’s award to supply a combined 55 MW of GenEco electrolyzers across three UK green hydrogen projects: Barrow, Trafford, and Langage.

Together, the three projects serve as blueprints for industrial decarbonization and energy security, advancing the UK’s low-carbon hydrogen ambitions.
