Propellant-Free Propulsion System
Propellant-free electric propulsion converting electrical energy directly into thrust for orbital maneuvering, station-keeping, and deorbiting — no reaction mass, no hazardous materials.
Description
Genergo's Propellant-Free Propulsion System represents a breakthrough in spacecraft mobility, operating without propellant or reaction mass of any kind. The system converts electrical energy directly into thrust using a proprietary mechanism that enables sustained in-space maneuvering across a wide range of mission profiles — from small CubeSats to larger satellite platforms.
With more than 1,300 hours of validated on-orbit operation across three missions (GEN01 in May 2022, GEN02 in January 2023, and GEN03 in November 2023), all launched on SpaceX Transporter rideshare flights, the system has demonstrated exceptional reliability under real space conditions. The technology has reached TRL 7/8, verified through independent analysis of flight data from all three missions.
The system is designed for scalability, accommodating a range of spacecraft sizes and power budgets with modest electrical power requirements — no high-pressure tanks, no complex feed systems, and no hazardous propellants. This dramatically simplifies spacecraft integration, eliminates safety risks during ground handling and launch, and removes the risk of propellant contamination of co-manifested payloads or the space environment.
Key mission applications include orbital station-keeping for maintaining precise constellation slots, orbital maneuver execution for altitude and inclination adjustments, and propulsive deorbiting at end of mission — directly addressing the growing regulatory pressure for responsible satellite disposal. The absence of consumable propellant means the system's operational lifetime is limited only by electrical power availability and system wear, not propellant depletion.
