The Clean Aviation Joint Undertaking (CAJU) is a successful public-private partnership between the European Commission and the European aeronautics industry that is on the way to achieving its environmental performance targets.
The Clean Aviation JU will develop disruptive new aircraft technologies to support the European Green Deal, and climate neutrality by 2050. These technologies will deliver net greenhouse gas (GHG) reductions of no less than 30%, compared to 2020 state-of-the-art. The technological and industrial readiness will allow the deployment of new aircraft incorporating these technologies no later than 2035, enabling 75% of the world’s civil aviation fleet to be replaced by 2050. The aircraft developed will enable net CO2 reductions of up to 90% when combined with the effect of sustainable ‘drop-in’ fuels, or zero CO2 emissions in flight when using hydrogen as energy source.
Clean Aviation’s aeronautics-related research and innovation activities, focusing on breakthrough technology initiatives, will contribute to the global sustainable competitiveness of the European aviation industry. European aviation research and innovation capacity will be strengthened through the partnership, enabling new and ambitious global standards to be set.
Development and demonstration of the hydrogen distribution and conditioning system, from the tank interface until the combustor, for a direct hydrogen combustion propulsion aircraft. This topic targets the demonstration of the critical distribution and hydrogen conditioning components, including the high-pressure hydrogen pump, at TRL5, and the on-ground demonstration of the fuel distribution system at TRL4. The project will perform a scaled-on ground demonstration of the engine thrust control function. See the topic description document published with this call for full details.
The configurations of the Hydrogen Powered Aircraft concepts addressed in Clean Aviation are expected to remain a tube and wing. Such aircraft concepts are based on either a direct hydrogen combustion propulsion or a fully-electric hydrogen fuel cell propulsion, with a target Entry into Service in the 2040s. This topic focuses on the aircraft concept based on direct hydrogen combustion propulsion, which is expected to have a capacity between 120 and 150 passengers and a minimum design range of 1400 nautical miles.
The project aims to develop and demonstrate the fuel system architecture, with a focus on the highpressure hydrogen distribution system and components, enabling the supply of a hydrogen combustion engine with 150kN of thrust (per engine, for a two-engine aircraft configuration) capable to power the Clean Aviation direct hydrogen combustion propulsion aircraft concept addressed in the SRIA.
