Alpha Impulsion is a Franco-Italian start-up developing autophage propulsion, a breakthrough technology in which the engine consumes its own structure as propellant. This approach aims to make propulsion lighter, more efficient and more sustainable, from launch to in-space operations. After hot-firing the world’s largest autophage rocket engine in 2025, the company is developing Opal, an in-space autophage thruster, and Grenat, a dedicated light launcher designed to strengthen European sovereign access to orbit.
