BP and Iberdrola have begun construction on Spain’s largest green hydrogen plant.

The 25MW plant could create up to 500 jobs during its construction and around 25 Spanish companies will take part in the build-out.

The first phase involves earthworks and preparation of a plot of land next to the BP refinery in Castellón.

Civil work will begin in the second quarter of the year.

The next milestone will be the installation of the first major equipment, including electrolysers, targeted for the second half of 2025.

This equipment is what allows green hydrogen to be produced through a chemical process – electrolysis – capable of separating the hydrogen and oxygen molecules that make up water using electricity from renewable sources.
