Low-Cost Green Hydrogen Rocket Engines for Competitive European Space Access

transportTestedTRL 6

Imagine building a rocket engine like a Lego set, using 3D printing to make it cheaper and faster to assemble. Instead of guessing when a part might break, the engine uses a smart brain to monitor its own health in real-time. It runs on clean hydrogen, making it an eco-friendly way to get satellites into orbit.

The business problem

What needed solving

European space launchers face high costs and intense global competition. There is a critical need for reusable, low-cost, and green propulsion systems to maintain independent access to space.

The solution

What was built

A demonstrator of a green high-thrust engine (GTHE) using liquid hydrogen, featuring 3D-printed parts and an AI-based health monitoring system.

Aerospace
enterprise
Target: Satellite Launch Provider

If you are a launch provider dealing with high operational costs — this project developed a green high-thrust engine that aims to halve launch prices in the short term. This allows for more frequent and affordable missions to space.

Advanced Manufacturing
SME
Target: 3D Printing Specialist

If you are a manufacturer dealing with complex part assembly — this project developed extended additive manufacturing techniques to reduce the number of engine parts. This streamlines production and lowers the cost of high-power hardware.

Predictive Maintenance
any
Target: AI Software Firm

If you are a software company dealing with hardware failure risks — this project developed an AI-driven health monitoring system. This enables the reusability of engines by predicting maintenance needs before a failure occurs.
