Green hydrogen project Hysencia advances Aragón's clean energy future

The Government of Aragón has designated DH2 Energy's Hysencia project of regional interest, and the project secured €8 million in the EU Hydrogen Bank's first auction.

DH2 Energy's Hysencia project has received formal regional interest status from the Government of Aragón and was awarded funding in the EU Hydrogen Bank auction. The plan is to build a green hydrogen production plant at Plasencia del Monte that pairs a large solar PV array with a water electrolyzer to produce hydrogen powered by solar energy. The project holds an environmental permit issued last summer and is finalising detailed engineering ahead of planned construction later this year. The build will be staged, starting with solar assets and grid connection followed by electrolyzer and hydrogen handling equipment. Testing and commissioning are scheduled for early next year, with full hydrogen output expected by mid-decade, subject to weather and grid integration timelines. Key details: - The Government of Aragón designated the Hysencia project as of regional interest. - The project secured €8 million in the EU Hydrogen Bank's inaugural auction, selected from 132 bids. - The plant pairs a 49 MWp solar PV array with a 35 MW electrolyzer, expected to capture about 99 GWh of renewable energy and produce an estimated 1,700–2,075 tonnes of green hydrogen annually. - The site covers roughly 100 hectares and includes a 10 MW grid link as backup; construction will proceed in two main stages (solar and grid works, then electrolyzer and hydrogen systems). - Projected benefits reported include annual avoidance of about 16,000 tonnes of CO₂ and an estimated lifetime regional GDP uplift of over €130 million. Summary: The Hysencia project is expected to contribute to regional decarbonization, local industrial supply and energy security while creating construction and operational roles in Huesca province. Planned activities include finalising engineering, starting construction in the latter half of the year, and completing testing and commissioning ahead of phased hydrogen production by mid-decade.
