Imagine replacing jet fuel with hydrogen gas to make planes that don't emit CO2. This work focuses on building the 'stove' (combustor) and the 'fuel lines' (fuel system) needed to make this happen. It's like redesigning a car engine to run on a completely different gas while ensuring it stays safe and efficient at high altitudes.
Aviation faces strict mandates to eliminate CO2 emissions, but hydrogen combustion requires entirely new engine architectures and fuel delivery systems that are not yet mature.
A technology maturation plan including an H2 combustor, an H2 fuel system (TRL2), and additive manufacturing trials for low NOx injectors.
If you are an engine manufacturer dealing with strict carbon mandates — this project developed an H2 combustor and fuel system that enables a zero-CO2 flight. This allows for a target Entry Into Service by 2035.
If you are an airline operator dealing with the European Green Deal requirements — this project developed the technical basis for H2C propulsion that reduces CO2 emissions. This supports the transition to non-drop-in fuels.
If you are a 3D printing company dealing with complex aerospace parts — this project developed additive manufacturing trials for low NOx injection systems. This proves the viability of 3D printing for high-performance hydrogen engine components.
Based on available project data, there is no information regarding the specific cost or price of the propulsion system.
The project is currently in the maturation phase, with the H2 Engine Fuel System reaching TRL2 and various combustor components undergoing test campaigns. It is not yet at industrial scale.
Based on available project data, specific IP or licensing terms are not disclosed, though the project involves a large consortium of 32 partners including GE AVIO.
The project aims for a technology maturation plan compatible with an Entry Into Service of zero-CO2 aircraft in 2035.
The project specifically investigates integration aspects between the engine and the aircraft, as well as the development of a ground Wet Rig configuration.
The project is heavily industry-driven with a 75% industry ratio, comprising 24 industrial partners out of 32 total members. Led by GE AVIO SRL, the consortium spans 9 countries, indicating a strong commercial interest in the results, particularly as they feed into Airbus's ZEROe project.
