Project summary
HYDROLAB aims to develop an integrated module for liquid hydrogen pumping and regulation. The system is designed to transfer cryogenic fuel safely, efficiently and in a controlled manner from onboard or ground tanks to the turbine interface or to equivalent test systems. Tanks and turbines are outside the project scope and will be provided by external partners or replaced by mock-ups.
Strategic objectives
Operational integration of LH₂
Support the integration of liquid hydrogen into propulsion systems for future zero-emission aircraft through scalable solutions adaptable to different applications.
Dynamic cryogenic flow control
Develop core technologies for valves, pumps and sensors under aeronautical operating conditions, with strict reliability, safety and performance requirements.
Engineering and scientific know-how
Generate know-how through experimentation, numerical modelling and prototyping, transferring results to higher-TRL programmes, flight testing and industrialisation.
Programme scope
Global analysis of hydrogen distribution systems and end-user needs in the aerospace and energy sectors.
Selection and development of innovative materials for pumps, valves and intermediate tanks under extreme cryogenic conditions.
Design of lightweight, high-efficiency cryogenic pumps with embedded electric motors, minimising mass and energy consumption.
Development of a test bench initially powered by LN₂ and subsequently by LH₂ for experimental characterisation and prototype validation.
Study of safety interfaces and real-time monitoring of pressure, flow and temperature during cryogenic transfer operations.
Methodological approach and operational phases
Conceptual design and numerical modelling
Definition of the system architecture and simulation of fluid behaviour under different operating conditions.
Material compatibility
Verification of metals, polymers and composites at −253 °C, focusing on brittleness, thermal stress and chemical interactions.
Prototyping and similarity testing
Initial testing with liquid nitrogen to reduce risk, followed by liquid hydrogen tests in transfer and regulation scenarios.
Digital Twin
A digital replica of the physical subsystem to support control, diagnostics and predictive maintenance.
Expected deliverables
- Engineering solutions validated up to TRL 4 and ready for further development in flight-test or industrial-demonstrator contexts.
- Comprehensive material compatibility report including experimental data, risk analysis and design recommendations.
- Experimental dataset and validated numerical model for simulation and system optimisation activities.
- Technical dossier for technology transfer to industrial partners and higher-TRL projects.
Expected impact
- Technological enablement for the transition to liquid hydrogen as aviation fuel.
- Strengthening of the European hydrogen value chain through aerospace competences, infrastructure and components.
- Reduction of direct CO₂ emissions, with potential dual-use spillovers and long-range mobility applications.
