H2Pro and Sun Systems are considering up to 150 MW of solar-powered hydrogen production in Spain.

Israeli electrolyser company H2Pro and Spanish solar firm Sun Systems Group have reached a memorandum of understanding (MoU) to create a completely off-grid, solar-powered green hydrogen initiative in Tarragona, Spain, aiming for an electrolyser capacity of up to 150 MW by 2032.

The proposed project will integrate H2Pro’s electrolysers, which operate directly on fluctuating renewable energy, with dedicated solar power from Sun Systems Group, without depending on grid electricity. The companies claim it will be the first fully off-grid solar-to-hydrogen project in the Tarragona area.

This initiative will be executed in stages, beginning with a 25-MW electrolyser that will generate approximately 1,250 tonnes of hydrogen annually, increasing to 50 MW and ultimately achieving 150 MW by 2032. Hydrogen production will be supported by up to 220 MWp of solar capacity developed under a specific self-consumption framework.

The project is intended to qualify as a renewable fuel of non-biological origin (RFNBO). Initially, its output will cater to industrial clients, especially in the chemical and petrochemical industries, and will be blended into Enagas' natural gas transport network. In the long run, the project is also designed to support the projected establishment of Spain’s hydrogen backbone and the H2Med corridor.

The MoU with Sun Systems comes after H2Pro announced a collaboration with Doral Hydrogen to jointly develop a 5-MW solar-powered hydrogen project in Spain’s Extremadura region.
