Green Propulsion Systems and Design Roadmaps for Regional and Long-Haul Aircraft

transportPrototypeTRL 3

Imagine replacing a plane's thirsty gas engine with a mix of electric motors and hydrogen fuel, similar to how a hybrid car works but for the skies. The team is building better cooling systems for fuel cells to make them lighter and more powerful. They are also designing a blueprint for how different sized planes, from small regional hops to big jets, can stop polluting.

The business problem

What needed solving

Aviation faces strict environmental targets but lacks a clear path to replace kerosene for different aircraft sizes. Current electric and hydrogen solutions are often too heavy or inefficient for commercial use.

The solution

What was built

A hybrid turbo-electric gearbox, a high-efficiency fuel cell cooling system, and a liquid hydrogen fuel system. They also produced preliminary designs for an 80-seat regional plane and a 150-seat jetliner.

Who can put this to work

Aerospace Manufacturing
enterprise
Target: Regional aircraft manufacturer

If you are a regional aircraft manufacturer dealing with strict CO2 targets — this project developed a design for an 80-seat 1000-km range propeller aircraft using hybrid turbo-electric propulsion that reduces emissions.

Energy Systems
SME
Target: Fuel cell component supplier

If you are a fuel cell supplier dealing with overheating and heavy equipment — this project developed novel phase cooling that can increase net power by up to 20% and improve power-to-weight ratios by up to 80%.

Aviation Logistics
enterprise
Target: Jetliner operator

If you are a jetliner operator dealing with the transition to carbon-free flight — this project developed a design for a 150-seat 2000-km range jet liner using liquid hydrogen fuel and cryogenic tanks.

Frequently asked

Quick answers

What is the estimated cost or price of these systems?

Based on available project data, specific unit costs for the propulsion systems or aircraft designs are not provided.

Is this technology ready for industrial scale?

The project focuses on TRL3 demonstrations, meaning it is currently at the proof-of-concept stage on test benches and not yet at industrial scale.

Are there IP or licensing opportunities?

Based on available project data, the project involves the development of specific gearboxes and cooling systems, but licensing terms are not detailed.

How does this integrate with existing aircraft?

The project provides preliminary designs for 80-seat and 150-seat aircraft, focusing on the integration of cryogenic tanks and hybrid propulsion systems.

What is the timeline for deployment?

The project runs from 2023 to 2026, culminating in a road map that defines the maturation time for each technology class.

Consortium

Who built it

The consortium is heavily industry-weighted with a 55% industry ratio, comprising 6 industrial partners and 2 SMEs across 6 countries. This suggests a strong focus on practical application and manufacturing feasibility, supported by 4 universities and 1 research center to handle the TRL3 technical validations.
