Tomorrow’s Motion GmbH (TOMO) is developing a propulsion technology that aims to change how satellites move in space. Rather than relying on chemical propellants, the system employs electromagnetic principles to generate thrust using only electric power. This innovation significantly reduces satellite weight and prolongs operational lifetime by eliminating the risk of “running out” of fuel. It also offers an effective way to deorbit satellites at end of life.

Working in collaboration with Vision-Elektrik, TOMO has explored integrating high-temperature superconductive inductors—familiar from fusion research—into its propulsion drive. These inductors, cooled to achieve near-zero electrical resistance, drastically enhance thrust performance while substantially lowering power consumption. A custom-developed power supply, capable of delivering up to 500 A at just 0.5–2 V, provides the precise current needed to energise the superconductors. This same supply concept has direct relevance for other superconducting applications in fusion research, where stable high-current, low-voltage drivers are key for advanced magnet systems.

In a recent test phase, the team achieved a 26-fold improvement in thrust performance, with indications that up to a 60-fold increase is feasible. Looking ahead, TOMO plans to refine the design further, aiming for a 100-fold thrust boost and crossing the 1-newton propulsion force threshold with a unit weighing under 10 kilograms. Significantly, the propulsion technology is slated for in-space testing in about two years, marking a major milestone toward commercial satellite deployment.

By applying high-temperature superconducting technologies already central to fusion research, TOMO’s project underscores the powerful synergy between space exploration and fusion science. Such technology transfer demonstrates how improvements in superconductor power supply and magnet design can accelerate innovations in multiple fields.
