Viraj H2
Hybrid hydrogen aircraft propulsion
About Viraj H2
Viraj H2 develops hybrid hydrogen propulsion for aviation that combines fuel cells with turbomachinery. The architecture recovers water vapor produced by the fuel cell and reinjects it into the turbine to improve efficiency, power density, and reduce NOx—addressing both CO2 and non-CO2 climate effects of flight.
Public coverage describes a Toulouse-area startup pursuing prototype research with ISAE-SUPAERO and incubator support, aiming to offer this hybrid propulsion architecture for future hydrogen aircraft. Positioning is decarbonized aviation through propulsion architecture rather than airframe design alone.
Viraj H2 develops aircraft propulsion technology for OEMs and aviation partners. The business model is deep-tech propulsion R&D and licensing / systems supply. Related public materials also use the Viraj Aero brand for steam-injection turbine work.
