HYDROS™ Water Electrolysis Thruster
Green Propellant, High-Thrust
Orbit Agility™ Propulsion for SmallSats

Summary: To enable small, low-cost spacecraft platforms such as CubeSat, nanosats, and microsats to perform missions requiring orbit agility and stationkeeping, TUI has developed the HYDROS Propulsion System. The HYDROS Propulsion System uses on-orbit electrolysis of water to generate hydrogen and oxygen propellant, which are fed to a simple bipropellant thruster. To enable this, we have developed a compact electrolysis cell designed to operate in microgravity. HYDROS enables you to launch your CubeSat with an inert, green propellant - water - and use solar power to provide high thrust and high specific impulse propulsion. The HYDROS system can provide 100 Ns per 100 ml of water, and is readily scalable to provide larger ∆V's.



The HYDROS Propulsion System will initially be available in two standard configurations: a 2U HYDROS-C module intended for CubeSats and NanoSats, and a HYDROS-M module intended for 50-180 kg microsatellites. TUI can also develop customized tank configurations of these modules for your spacecraft for a reasonable NRE cost.

Status/Availability: The HYDROS-M flight units are currently shipping with flight heritage anticipated by late 2018. HYDROS-C flight units are expected to ship in early 2018.
