In an era of depleting fossil fuel supplies and climate change, efforts are being stepped up across the globe to make renewable energy usable and mobility emission-free. Hydrogen as a fuel source promises high systemic storage density and fast refuelling.

A challenge that hydrogen technology has yet to overcome satisfactorily is that of storage in the vehicle. The concept of cryo-compressed hydrogen storage is however, making advances in terms of storage density, safety and costs. The aim of the joint CryoSys project is to prove the suitability of cryo-compressed hydrogen fuel tanks for use in vehicles in addition to an analysis of their suitability for application in aviation. Within the framework of the project, investigations will be conducted that include fire and vacuum rupturing tests and an evaluation of energy release following sudden tank failure as well as examining operational stability and various other functions. The inventor of the cryo-compression technology, BMW, has been able to secure partners for the consortium that boast great expertise in the field of hydrogen technology.

Among them is ET EnergieTechnologie GmbH, specialised in conducting tests on complete tank systems, the Karlsruher Institut für Technologie (Karlsruhe Institute of Technology) expert in the simulation and experimental validation of safety-critical hydrogen subjects, as well as Airbus Operations GmbH as the partner for the assessment of aviation applications.
