Repsol advances 100MW electrolyser

Green hydrogen will be used to decarbonise Cartagena refinery and other local industry applications in southern Spain

A consortium led by Spanish energy firm Repsol has advanced plans for the installation of a 100MW electrolyser in southern Spain. The €215mn ($212mn) electrolyser will be situated in the Escombreras Valley near Cartagena and will produce green hydrogen that will be used to displace natural gas in local industrial applications. Repsol owns and operates a large refinery at Cartagena that will replace the grey hydrogen used in its operations with green hydrogen from the electrolyser. French utility Engie, which is also a partner in the electrolyser project, will use the hydrogen to create heat in its industrial processes. Meanwhile, renewable oxygen, produced by the electrolyser alongside hydro
