Hydrogen peroxide-based green chemical propulsion

Hydrogen peroxide‑based green chemical propulsion uses high‑concentration hydrogen peroxide as the oxidizer, combined either with a proprietary fuel (in bipropellant systems) or decomposed alone in monopropellant configurations, to generate hot gas that produces thrust for satellites and spacecraft.[1][6] It is termed "green" because hydrogen peroxide is significantly less toxic and easier to handle than hydrazine, the traditional spacecraft propellant, reducing ground handling risks and infrastructure requirements while still enabling efficient orbital manoeuvres, attitude control, and deorbiting.[5]
