Test Field "Liquid hydrogen storage"
Hydrogen has the highest weight-related energy density of all known fuels and is therefore ideally suited for aviation systems. Previous systems have mainly relied on compressed, gaseous hydrogen, but this is no longer practical for the performance class addressed by the BALIS project because the weight and volume of the tanks would be too large. The project therefore uses liquid hydrogen with a boiling point of -253 °C.
In order to supply the fuel cell system with gaseous hydrogen, the storage system must also have a vaporisation unit. Starting from an existing liquid hydrogen storage system, this technology must be scaled up considerably while maintaining safety and a high energy density. Among other things, the hydrogen flow to the fuel cell system and the temperature in the liquid hydrogen tank are measured in this test field.
