VW T5 with hydrogen fuel cell drive

We are working on converting heavy trucks and public transport buses for our partner Clean Logistics into hydrogen-powered HyBatt trucks and HyBatt buses. This VW T5 serves us as a valuable technology carrier. The transporter, which has been converted from diesel to hydrogen fuel cell drive, collects valuable data as a test vehicle on the interaction of the components used, such as the electric motor, fuel cell, hydrogen tank system, battery storage, high-voltage cabling and control units. The collected data and knowledge will be incorporated into the conversion of the HyBatt vehicles and contribute to the further optimisation of our processes.
