Spanish renewables company Acciona Energia and US hydrogen fuel cells specialist Plug Power Inc are jointly developing a 25-MW electrolysis project in the region of Navarre, northern Spain, to produce green hydrogen for industrial and mobility applications.

AccionaPlug expects the Valle H2V Navarra facilities to produce around 3,880 tonnes of green hydrogen per year. The plan is to deliver 90% of this output to energy-intensive industrial consumers in the area and use the remaining 10% to feed a hydrogen filling station at the same location.
