OHMSPACE S.R.L.

The space economy has entered a new phase. The proliferation of low-orbit satellite constellations, the growth of commercial Earth observation services, and the first missions toward the Moon and Mars are creating demand for propulsion systems that the market cannot yet fully satisfy. OhmSpace, a Rome-based aerospace startup, has chosen to occupy this space by designing high-performance electric propulsion systems for spacecraft. Electric propulsion — including technologies such as ion engines and Hall-effect thrusters — offers significant advantages over traditional chemical propulsion in terms of propellant efficiency, measured by specific impulse. For satellites that need to maintain their orbit for years, or for probes undertaking long orbital transfers, this translates into a dramatic reduction in the propellant mass carried on board and an extension of the vehicle's operational life. OhmSpace develops a full range of propulsion systems designed to be sustainable, reliable, and economically advantageous for the customers that adopt them. The target market includes operators of commercial, institutional, and defence satellites, builders of orbital platforms, and companies developing next-generation space infrastructure. The business model is B2B, oriented towards solutions tailored to the specific missions of each customer. Customisation is inevitable in a sector where every vehicle has different mass, power, and delta-V requirements, but it also creates deep technical relationships that represent a natural competitive barrier. In a space ecosystem that is commercialising at a sustained pace, propulsion remains one of the main bottlenecks for vehicle autonomy and longevity. OhmSpace positions itself to become a reference supplier in a market that will grow alongside the expansion of orbital infrastructure.
