Viraj Aero develops an innovative, low-carbon aircraft propulsion system based on steam injection technology. Their patented technology recovers water from exhaust gases and reinjects it as steam into the turbine, reducing fuel consumption by up to 35%. The system also cuts CO2 and non-CO2 emissions by up to 75%. The company raised a €4.5 million Seed round in August 2026, led by IRDI Capital Investissement.
