Sunfire has received a major order for two electrolysers, each with a capacity of 100 megawatts, for hydrogen projects in Spain. The plants are to produce green hydrogen from 2029 in Repsol's refineries in Cartagena and Muskiz (Bilbao). The clients are Repsol and Enagás Renovable.
Ten modules per location
For both locations, Sunfire will supply ten pressurised alkaline modules, each with a capacity of 10 megawatts. The electrolysers will be integrated into the existing refinery processes. According to the company, each of the two plants is expected to produce up to 15,000 tonnes of green hydrogen annually. This will be used to produce fuels with a reduced CO₂ footprint. Repsol expects to avoid up to 167,000 tonnes of CO₂ emissions per location annually by using the hydrogen.
Part of the national hydrogen strategy
The projects are considered part of Spain's strategy to decarbonise industry and reduce dependence on fossil energy imports. Repsol plans to gradually replace fossil hydrogen with green hydrogen at its industrial sites. The plants in Cartagena and Muskiz are to contribute to the regional hydrogen infrastructure.
Expansion of existing partnerships
Sunfire had previously supplied a 10 MW electrolyser to the Basque Hydrogen project, which is supported by Petronor, EVE, and Enagás Renovable. The plant is currently being installed at the Port of Bilbao. The Petronor refinery is owned by Repsol and Kutxabank. The new 200 MW order is seen as confirmation of the scalability and reliability of Sunfire's technology.
"Spain offers strong conditions for green hydrogen, and we recognised this potential early on," says Sunfire CEO Nils Aldag. "We are pleased that Repsol is once again relying on our proven pressurised alkaline technology to produce renewable hydrogen on an industrial scale."
Background: Sunfire
Sunfire develops and produces industrial electrolysers based on pressurised alkaline (AEL) and solid oxide technology (SOEC). The company, based in Germany, employs over 700 people. Other reference projects include a 100 MW order from RWE for the Lingen site.
