The media outlet Les Deeptech has published a profile of Joseph Risson, co-founder of VIRAJ H2, looking back on his career as an engineer trained at ISAE-SUPAERO and his commitment to accelerating the decarbonisation of aviation. The article, published in early June 2025, highlights Joseph's entrepreneurial spirit and our team's ambition: to increase propulsion efficiency and reduce environmental impact through innovative architecture based on hydrogen and steam injection.
