H2Pro and Sun Systems plan a 150-MW off-grid solar hydrogen project in Spain, supporting industrial decarbonization and future hydrogen infrastructure.
Israeli electrolyser technology company H2Pro and Spanish renewable energy developer Sun Systems Group have signed a memorandum of understanding (MoU) to jointly evaluate the development of a fully off-grid, solar-powered green hydrogen production facility in Tarragona, Spain. The ambitious initiative aims to establish up to 150 MW of electrolyser capacity by 2032, marking a significant step toward advancing Spain’s renewable hydrogen ecosystem and supporting the country’s broader decarbonization goals.
The proposed project is designed to operate entirely on dedicated solar energy without relying on electricity from the national grid. By combining H2Pro’s advanced electrolyser technology with solar generation assets developed by Sun Systems Group, the partners intend to create a self-sustaining hydrogen production system capable of converting renewable solar power directly into green hydrogen. According to the companies, the facility would represent the first fully off-grid solar-to-hydrogen project in the Tarragona region, showcasing an innovative model for renewable fuel production.
A key aspect of the project is the deployment of H2Pro’s electrolysers, which are engineered to operate efficiently under variable renewable energy conditions. Unlike conventional hydrogen production systems that often require a stable electricity supply, H2Pro’s technology is designed to work directly with fluctuating solar power generation. This capability eliminates the need for grid dependence and enhances the economic viability of producing green hydrogen exclusively from renewable sources.
The development is planned to progress in multiple phases over the coming years. The first stage will involve the installation of a 25-MW electrolyser facility capable of producing approximately 1,250 tonnes of green hydrogen annually. Following successful implementation and scaling, the project is expected to expand to 50 MW before reaching its ultimate target of 150 MW of electrolyser capacity by 2032. To support hydrogen generation at full scale, the initiative will be backed by as much as 220 MWp of dedicated solar photovoltaic capacity developed under a self-consumption framework.
The hydrogen generated through the project is expected to qualify as a Renewable Fuel of Non-Biological Origin (RFNBO), a category recognized under European Union regulations for sustainable fuels produced from renewable electricity. Achieving RFNBO certification would enhance the commercial attractiveness of the hydrogen while helping industries meet increasingly stringent environmental and carbon-reduction requirements.
Initially, the hydrogen output will be directed toward industrial customers, with particular emphasis on the chemical and petrochemical sectors, which are among the largest consumers of hydrogen in Europe. In addition, part of the production is expected to be blended into the natural gas transportation network operated by Enagás, supporting efforts to reduce emissions within existing energy infrastructure.
Looking further ahead, the project is strategically positioned to contribute to Spain’s emerging hydrogen economy. The developers anticipate that future hydrogen production could support the planned national hydrogen backbone infrastructure as well as the H2Med corridor, a major cross-border hydrogen transport initiative aimed at connecting renewable hydrogen production centers in the Iberian Peninsula with key industrial markets across Europe.
The agreement with Sun Systems Group follows another recent move by H2Pro to strengthen its presence in Spain’s renewable hydrogen sector. Earlier, the company announced a partnership with Doral Hydrogen to develop a separate 5-MW solar-powered hydrogen project in the Extremadura region. Together, these initiatives highlight H2Pro’s growing commitment to accelerating green hydrogen deployment in Spain and supporting Europe’s transition toward a cleaner and more sustainable energy future.
