Hydrogen Fuel System Design for Zero-Emission Commercial Aircraft Engines

transportPrototypeTRL 4

Imagine swapping a gas tank in a car for a high-tech hydrogen system that doesn't pollute. This work focused on the 'plumbing' and safety shells needed to get hydrogen fuel into a jet engine safely. It's like designing the specialized pipes and heat recovery systems needed to make a plane fly on clean energy instead of kerosene.

The business problem

What needed solving

Current aircraft engines rely on carbon-emitting fuels. Transitioning to hydrogen requires entirely new fuel delivery systems and thermal management to prevent leaks and manage extreme heat.

The solution

What was built

Conceptual designs for an H2 engine fuel system, Waste Heat Recovery (WHR) equipment, and structural architecture for propulsion capsules and nacelles.

Frequently asked

Quick answers

What is the estimated cost or price of the developed system?

Based on available project data, no specific cost or pricing information for the fuel system was provided.

Is this technology ready for industrial scale production?

The project reached the conceptual design review phase and shifted focus toward ground testing and wet rig configurations, meaning it is not yet at industrial scale.

Who owns the IP and how is licensing handled?

Based on available project data, specific IP or licensing agreements are not listed, though the project was coordinated by Safran Aircraft Engines.

What is the timeline for commercial deployment?

The project supported a technology maturation plan aiming for an Entry Into Service of a zero CO2 aircraft in 2035.

How does this integrate with existing aircraft structures?

The project focused on the structural architecture of the propulsion system, including the design of capsules, stubs, and ventilation systems within the nacelle.

Consortium

Who built it

The consortium is heavily industry-driven, with 20 industrial partners representing 95% of the group. Led by Safran Aircraft Engines, the collaboration spans 6 countries (BE, DE, FR, IT, PL, TR), indicating a strong commercial interest in hydrogen propulsion and a lean research-to-market pipeline with only one research entity involved.
