| Summary: | Hybrid rocket engines (HREs) offer a low-cost, reliable, and environmentally friendly solution for both launch and in-space applications. Hybrid propellants have been identified as green thanks to their use of non-toxic, non-carcinogenic oxidizers. Of particular relevance are storable oxidizers, namely high-concentration (≥90 wt.%) hydrogen peroxide (HP, H<sub>2</sub>O<sub>2</sub>) and nitrous oxide (N<sub>2</sub>O). This work provides a survey of experimental activities based on H<sub>2</sub>O<sub>2</sub> and N<sub>2</sub>O for hybrid rocket propulsion applications. Open literature data are completed with original thermochemical calculations to support the discussion. |
