Aviation Challenges
1. Aviation need to move to zero carbon net emissions by 2050
require early development and flight test to mature the technology
2. Mid size CS23 aircraft (~5T and ~500NM) require a lot of energy
not possible with battery or gaseous H2
3. Need early solutions with an efficient Time-To-Market (<8years),
not possible by redesigning brand new aircraft
4. Hydrogen infrastructures are not ready
We provide sustainable solutions with our aircraft by :
1. adopting Hydrogen (H2) as this is a very promising energy (3 times the kerosene one)
2. introducing the first Liquid (cryogenic) H2 tank inside the aircraft
3. adapting an existing aircraft to get ready before 2035
4. fostering a consortium of expert & industries to deploy mobile LH2 stations
A system combining batteries and fuel cells to produce electricity. Indeed, battery have a good power density (means great to deliver power peak) and fuel cell system coupled to liquid storage are really good for energy density (means sustain a long flight). The best of both are then used to deliver a viable product.
It’s clean, efficient, and sustainable. yes but most importantly it is the more efficient state of hydrogen to be carried into an airplane. Volume and mass are in favor compared to gaseous state whatever the pressure of the vessels.
Key figure is called the gravimetry index, which means the ratio of H2 mass over the total mass of the system that carries the hydrogen. For instance:
tank for LH2 (Liquid Hydrogen) is about 20%
vs.
700bar Gaseous Hydrogen vessel is about 5 to 7%
1. To create a zero emission fly affordable by 2035
2. To reinforce the hydrogen industry by providing a liquid hydrogen aircraft
3. To create an affordable hydrogen-powered aircraft
