Sunfire is a German industrial electrolysis company that designs and manufactures systems for producing renewable hydrogen and syngas. Its portfolio includes high‑temperature solid oxide electrolysis (SOEC) technology, which uses steam—and can co‑electrolyze CO2—to achieve high electrical efficiency, as well as pressurized alkaline electrolyzers suited to large-scale, grid‑connected plants.
Sunfire’s multi‑megawatt electrolyzer modules are deployed in sectors such as refining, chemicals, steel, and power‑to‑liquids, enabling replacement of fossil-based hydrogen and supporting Power‑to‑X pathways for products like green ammonia and methanol. Founded in 2010 and headquartered in Dresden, Germany, the company also provides engineering, integration support, and lifecycle services for industrial projects.
