Hydrogen Peroxide Propulsion
Proven Efficiency, Safer Operations

We use High-concentration Hydrogen Peroxide as the Foundation of Our Green Propulsion Technology.

This propellant offers a powerful combination of performance, safety, and sustainability — delivering high efficiency and precise control while being far safer to handle than traditional toxic propellants.

When paired with Arkadia’s proprietary fuel, hydrogen peroxide also enables hypergolic ignition, allowing engines to ignite instantly upon propellant contact. This unique capability eliminates the need for complex ignition systems, increases reliability, and provides the rapid response required for demanding manoeuvres.

The Science Behind
Hypergolic Propellants

Hypergolicity refers to a propellant pair (oxidant and fuel) that ignites spontaneously upon contact, removing the need for an external igniter. Arkadia Space has developed propulsion systems capable of hypergolic ignition when mission profiles require it, delivering reliable, repeatable starts and fast restart capability—vital for reaction-control systems and multiple-burn maneuvers.

Compared with engines that require external ignition systems, hypergolic operation simplifies the propulsion architecture (fewer components and failure modes), reduces subsystem mass and power requirements, and enables faster, more deterministic response times for time-critical burns

Agile and affordable fueling operations

Our hydrogen peroxide systems enable fast, streamlined fueling with reduced complexity and lower costs. Fully aligned with modern launch requirements, they allow quicker integration and more frequent launch opportunities.

Efficient performance

Thanks to its high specific impulse (Isp) density, our propellant delivers more thrust per kilogram of fuel. This means greater maneuvering capability and improved mission efficiency for every gram onboard.

Verified sustainability (LCA-driven)

Our hydrogen peroxide technology is validated through Life Cycle Assessment (LCA), reducing environmental impact by up to 60% across manufacturing, operation, and disposal compared to traditional propellants.

Green Propulsion for Next Generation of Satellites

Our hydrogen-peroxide propulsion technology is the result of years of focused R&D — refined, reliable, and ready to scale. By designing and testing every component in-house, we deliver high performance with safer handling and faster operations than traditional propellants.

Monopropellants

Arkadia Space’s monopropellant engines are built around high-concentration hydrogen peroxide and deliver a simple, reliable solution for in-space manoeuvring and attitude control. By decomposing peroxide over an advanced catalytic bed, these engines produce instantaneous, controllable thrust with a very compact and low-complexity architecture. That simplicity translates into higher reliability, faster integration and easier ground operations, while remaining aligned with our green propulsion approach.

Bipropellants

Arkadia Space’s green bipropellant engines deliver dependable, high-performance thrust for larger satellites and in-space platforms (designed for platforms above 50 kg). Using a high-concentration hydrogen peroxide oxidizer paired with a proprietary fuel that Arkadia has developed and patented, our bipropellant engines achieve excellent density-specific impulse while reducing handling risks compared with traditional toxic propellants. Engineered for repeatable ignition, precise throttleability and long-duration mission profiles, these systems combine injector designs with lightweight, additively manufactured components to provide compact, efficient propulsion for orbital transfers, kick stages and complex manoeuvring tasks. Available across multiple thrust ranges, our engines are tailored to meet diverse mission requirements.

Hydrazine vs Hydrogen Peroxide
Cost & Complexity

By replacing traditional toxic propellants with high-concentration hydrogen peroxide, Arkadia significantly reduces operational and logistical costs. Our propellants are non-toxic, easy to handle, and compatible with standard industrial materials — cutting expenses on safety measures, transport, and ground operations.

Moreover, our fully in-house design, manufacturing, and testing processes eliminate external dependencies, shortening lead times and keeping costs under control without compromising performance or reliability.
