Heaven FCH

HEAVEN main goal is to design, develop and integrate the worldwide first aircraft powertrain based on high power density fuel cell system and high energy density liquid hydrogen fuel system into an existing 2-4 seats aircraft for testing in flight operation.

Cryogenic liquid hydrogen storage technology will be applied to aeronautical applications for the first time worldwide. This technology improves the current energy density of pressurized H2 tanks by a factor of 2 to 5, and leads to commercially viable performances.
A pressurized fuel cell system is demonstrated to increase the power density of the system by a factor of 2 to 3 and can operate at higher temperature, leading to fewer cooling efforts needed and thus a reduction of weight, power consumption and volume of the thermal management system.
Protocols based on safety analysis, redundancy of the powertrain, auxiliary systems, tests and simulations with the final goal of a flight demonstration will provide reliability figures in support of future certification.
