Sören Heizmann

Sören Heizmann is a scientific researcher and doctoral candidate at Technische Universität München (TUM) since 2022. He holds a Master of Science in Aerospace Engineering from the University of Stuttgart, Germany, and has accumulated extensive experience in space propulsion technology through roles at a Large System Integrator, a New Space company, and the European Space Agency (ESA/ESTEC).

Research Focus centers on developing spaceflight-capable high-pressure electrolysers for Water Electrolysis Propulsion (WEP), with additional work on system analysis and satellite integration of WEP technologies. As Technical and Innovation Manager of the S4I2T (Solar for Ice to Thrust) project, he leads development of a cleaner, more efficient in-space propulsion system that demonstrates propellant refilling between CubeSats and end-to-end ISRU technology chains.

• Specializes in water-based propulsion systems
• Expert in electrolyser design and testing
• Focuses on miniaturized satellite propulsion
• Advances sustainable space mobility

Projects include the EIC-funded S4I2T initiative and contributions to TUM's SPARK research center - the world's first university-focused space propulsion innovation hub. His work emphasizes reducing space debris through clean propulsion technologies, enabling autonomous orbital maneuvers, and developing commercial off-the-shelf (COTS) propulsion solutions.
