Imagine trying to carry a giant thermos of super-cold liquid hydrogen on a plane without the tank adding too much weight. Instead of just putting a tank inside the plane, this project tried to make the tank part of the plane's own structure. It used a digital twin—like a high-tech virtual mirror—to predict how the tank behaves during flight.
Hydrogen aircraft are hindered by heavy, non-structural fuel tanks that waste space and weight. Current certification processes for these hazardous systems are too slow and expensive for rapid commercialization.
The project produced system requirements, safety assessments, material permeability data for composites in LH2, and a digital twin model for thermal and structural evaluation.
If you are a cargo UAV operator dealing with short flight ranges and heavy batteries — this project developed a 1,000-liter load-bearing composite tank that increases energy density. This allows for longer flights and heavier payloads without adding dead weight.
If you are an aircraft manufacturer dealing with slow certification cycles for new fuels — this project developed a digital twin and fast-track flight testing method. This reduces the time-to-market for hydrogen-powered aircraft by using UAVs for high-risk validation.
If you are a materials producer dealing with hydrogen leakage in composites — this project developed a material screening campaign for LH2 permeability. This provides data on how composite samples behave when immersed in liquid hydrogen.
Based on available project data, specific cost or pricing information for the tank was not provided.
The project focused on a 1,000-liter relevant-scale tank, but the project was terminated before full manufacturing and flight testing were completed.
Based on available project data, there is no specific information regarding IP ownership or licensing agreements.
The project aimed to use a digital twin calibrated with flight data to support digitalized certification pathways for hydrogen technologies.
The project was scheduled from 2023-01-01 to 2025-12-31, though it was ultimately terminated early.
The consortium is heavily industry-driven with a 67% industry ratio, consisting of 4 industrial partners (including 2 SMEs), 1 university, and 1 research center across 4 countries. This structure indicates a strong push toward commercial application, though the termination suggests a gap in specialized manufacturing capabilities for the tank itself.
