Innovative solutions for clients at market prices
Around 15 GW of green hydrogen projects under development
Green hydrogen is supplied as feedstock (in place of grey hydrogen) or as a new energy source. DH2 Energy offer competitive solutions for different applications.
Our main markets are the Iberian Peninsula and Mexico. We are also active in other markets, including France and Uruguay.

Project in advanced development
A pioneering project: Hysencia
Hysencia is a green hydrogen production plant located in Aragón, Spain. This presentation introduces the project’s first phase, with construction expected to commence in the final quarter of 2025. Hysencia received its Integrated Environmental Authorisation in July 2024.
Designed as an on-site renewable hydrogen production facility powered by photovoltaic energy, Hysencia also includes a 10 MW grid connection for back-up supply. With 35 MW of electrolysis capacity and 49 MWp of solar photovoltaic power, it stands as one of the earliest and most advanced commercial green hydrogen projects in Europe.
The project was awarded funding in the inaugural auction run by the European Hydrogen Bank, financed by the European Union’s Innovation Fund and implemented by the European Climate, Infrastructure and Environment Executive Agency (CINEA). As part of this award, Hysencia will receive a premium of €0.48 per kilogram of renewable hydrogen produced during the first ten years of operation. This corresponds to an estimated total financial support of approximately €8 million.
