Hysun is a Spanish clean-tech company focused on generating cost-competitive green hydrogen by harnessing solar energy without relying on electricity-intensive electrolysis. Its proprietary system is currently being validated through a prototype installed at the Plataforma Solar de Almería, where the company aims to demonstrate real-world efficiency and scalability. By eliminating electricity from the process, Hysun targets production costs that could match the €1–2 /kg price of grey hydrogen, a significant reduction from the €6–8 /kg typical of today’s electrolytic green hydrogen. The company expects its breakthrough to accelerate industrial adoption of renewable hydrogen, especially in hard-to-electrify sectors such as heavy industry and transport. Backed by strategic investors with deep energy expertise, Hysun plans to use fresh capital to complete prototype testing, refine its technology, and position Spain as a reference hub for hydrogen innovation. The broader impact includes supporting European decarbonization goals, fostering specialized employment, and strengthening the regional clean-energy ecosystem.
