ISPTech offers not one, but two green propellants. The corresponding technologies are based on more than 10 years of research and development activities at the German Aerospace Center (DLR).
HyNOx
THE SELF-PRESSURIZING PROPELLANT
HyNOx is the combination of nitrous oxide (N2O) and ethane (C2H6). Both of these components are non-toxic, affordable and easily available.
The propellants are stored under saturated conditions in the tanks. They have a high vapor pressure in the relevant temperature range – enabling a simple system architecture. There is no need for a pressurant gas.
| Specific impulse (vacuum) | up to 300 s |
| Storage density | up to 700 kg/m³ for N2O up to 300 kg/m³ for C2H6 |
| Ignition | electric |
| Special features | cold-gas capable, no preheating |
| Suitable for | small spacecraft cost-driven applications |
The HyNOx Thruster Family.
Extensively tested. Steady-state capable.
HIP_11
THE GREEN HYPERGOLIC PROPELLANT
HIP_11 is a hypergolic propellant combination consisting of highly concentrated hydrogen peroxide (H2O2) and an ionic liquid fuel. Compared to conventional hypergolic propellants, it offers similar performance but higher density and significantly reduced hazards.
| Specific impulse (vacuum) | up to 310 s |
| Storage density | up to 1440 kg/m³ for 98% H2O2 up to 1100 kg/m³ for fuel |
| Ignition | hypergolic |
| Special features | no preheating, no catalyst |
| Suitable for | large spacecraft performance-driven applications |
HIGH PERFORMANCE.
HIGH DENSITY.
Green and hypergolic is no contradiction.
