What Sunfire does
Sunfire SE is a Dresden-headquartered industrial electrolysis company founded in 2010 that designs and manufactures electrolyzer systems for producing green hydrogen. It operates two complementary technology platforms: pressurized alkaline electrolysis (AEL), running at 30 bar(g) with 67% LHV DC efficiency and packaged into 5 MW stacks, 10 MW modules (HyLink Alkaline 22), and 50 MW outdoor modules (HyLink Alkaline 23); and solid oxide electrolysis (SOEC), operating at ~800°C with a world-record 89% LHV AC efficiency and delivered as a standardized 10 MW module (HyLink SOEC). The company maintains full value chain control, including cell production and electroplating at its Solingen subsidiary, automated assembly in Dresden and Magdeburg, and gigawatt-scale production capacity in Germany.
Sunfire sells electrolyzer modules and integrated plant solutions through a direct enterprise sales motion, targeting energy-intensive industries — refining, chemicals, steel, ammonia — as well as utilities and e-fuel/synthetic fuel producers. Revenue is generated via project-based multi-million-euro contracts with multi-year execution and service tails. Named customers include RWE (100 MW Lingen), Repsol (two 100 MW Spanish plants), TotalEnergies (SOEC for synthetic methanol), Petronor (100 MW Bilbao), MPREIS (10 MW Austrian deployment), Salzgitter Flachstahl (SOEC validation under GrInHy), and Neste (MultiPLHY SOEC consortium in Rotterdam). The company has secured €600M+ in 2024 financing, holds an 800+ MW order backlog, operates with 700+ employees, and reports €500M+ in cumulative funding raised.

Sunfire product offering
Product offeringCore offering
Sunfire designs, manufactures, and sells industrial-scale electrolyzer systems for green hydrogen production. Its portfolio covers two complementary technologies — pressurized alkaline electrolysis (AEL) delivered as the HyLink® Alkaline modules (10 MW and 50 MW outdoor units) and solid oxide electrolysis (SOEC) delivered as the HyLink® SOEC 10 MW module. The company provides full-scope project delivery including front-end engineering design, pre-assembly, on-site support, and maintenance/digital services for industrial customers.
Product overview
Sunfire offers an industrial electrolysis portfolio combining pressurized alkaline (AEL) and solid oxide (SOEC) technologies for green hydrogen production. The core product lineup consists of HyLink® Alkaline 23 (50 MW outdoor module for large-scale projects), HyLink® Alkaline 22 (10 MW module for projects up to 100 MW), and HyLink® SOEC (10 MW high-temperature system achieving 89% efficiency for heat-integrated applications). All products are built on German engineering with standardized modular designs enabling scalable deployment from single units to multi-gigawatt installations. The AEL systems use Sunfire's proven Gen 2 stack technology while SOEC represents next-generation solid oxide capability.
