Repsol has begun producing renewable hydrogen via a 2.5MW electrolyser at its Petronor industrial centre in Biscay, Spain.

With an investment of €11m, the facility’s electrolyser is expected to be capable of generating 350 tonnes per year of renewable hydrogen for industrial use, mainly in the refinery, as a raw material for manufacturing products with a lower carbon footprint.

Renewable hydrogen is used in the logistics platform of the Abanto Zierbana Technology Park (9.4 miles away) to power buses and heavy transport. Therefore, Repsol and the Basque Energy Agency have agreed to locate the Basque Country’s ‘first’ hydrogen refuelling station there, utilising the Petronor electrolyser via a Nortegas pipeline.

Repsol has revealed that Petronor will be the site for two more electrolysers, with a capacity of 10MW and 100MW, in the future, the latter already being recognised by the European Commission as an Important Project of Common European Interest (IPCEI).
