Call for proposals to support projects focusing on the development of secure, scalable, and cost-effective methods for producing stable isotopes within the EU.

About this grant

Call for proposals to support the development and demonstration of critical components for hydrogen fuel cell engines in fully electric aircraft. This initiative targets the tube and wing aircraft concept, specifically designed for a capacity of approximately 100 passengers and a design range of up to 1,000 nautical miles. The primary objective is to engineer a compact, lightweight, and high-performance propulsion system capable of delivering 2.5 MW of net power per engine in a four-engine configuration, supporting an expected entry into service in the 2040s. The project aims to mature fuel cell technology through a combination of physical and virtual demonstrations. Key deliverables include: The development of a 2.5 MW fuel cell propulsion system reaching Technology Readiness Level 4 (TRL4) via integrated virtual demonstration; The physical demonstration of critical sub-systems and components at TRL5, ensuring they are representative of the final propulsion architecture; A robust validation and verification strategy to confirm the manufacturing and assembly maturity of these components; An integration concept that strictly adheres to hydrogen safety requirements, including the management of leakages and risks such as fire or detonation; The achievement of Certification Readiness Level 4 (CRL4) for all critical technologies, with a clear roadmap toward CRL6. This call represents a significant investment, with a total available budget of €50M, which may be awarded to a single comprehensive project.
