Deadline: 19-May-2026
The European Commission is inviting applications for a grant to support the design and demonstration of a hydrogen distribution and conditioning system for direct hydrogen combustion aircraft. The call focuses on advancing clean aviation technologies through ground demonstrations, high-pressure hydrogen system development, and improved technology readiness, with a total funding allocation of €329.5 million under Horizon Europe.
What is this grant about?
This grant supports the development of a hydrogen distribution and conditioning system for direct hydrogen combustion aircraft.
The aim is to help advance sustainable aviation technologies by improving how hydrogen is:
- Distributed from the tank interface to the combustor
- Conditioned for safe and efficient propulsion use
- Integrated into future hydrogen-powered aircraft systems
The project is intended to strengthen the technical foundation needed for clean aviation fuel systems.
Focus Areas
The call supports activities such as:
- Designing and demonstrating the hydrogen distribution system from the tank interface to the combustor
- Developing critical hydrogen distribution and conditioning components
- Advancing the high-pressure hydrogen pump to TRL5
- Conducting an on-ground demonstration of the fuel distribution system at TRL4
- Delivering a scaled on-ground demonstration of the engine thrust control function
Funding Amount
- Total funding available: €329,500,000
This is the total allocation mentioned for the initiative/call.
Project Objective
The project aims to:
- Improve the technology readiness of hydrogen propulsion systems
- Demonstrate fuel handling and distribution performance
- Support integration of high-pressure hydrogen pumps and conditioning units
- Advance technical maturity for future hydrogen-powered aircraft
- Strengthen the broader clean aviation ecosystem
