Advances in hydrogen refueling
HOERBIGER is driving forward the development of hydrogen refueling technology with its Refueling Data Interface (RDI), which reduces refueling times by up to 90%. Going further, the upcoming Vehicle Station Communication Interface (VSCI) aims to standardize the refueling process for medium and heavy-duty vehicles and contribute to the expansion of hydrogen infrastructure.
Innovations in hydrogen refueling are enhancing both efficiency and safety in the refueling of hydrogen-powered vehicles, whether they use fuel cells or hydrogen combustion engines. A key innovation is the Refueling Data Interface (RDI), which speeds up the refueling process by exchanging critical data wirelessly via safe infrared beams. This system captures parameters such as pressure, temperature and flow rate, ensuring compliance with strict industry standards. The RDI significantly shortens refueling time – by up to 90% – enabling vehicles to be refueled in just three minutes.
In addition, the Vehicle Station Communication Interface (VSCI) is currently in development to support the refueling of medium and heavy-duty vehicles. This system will also perform diagnostics during the refueling process, further enhancing the reliability of hydrogen infrastructure.
These technologies, already adopted by several leading automotive manufacturers, represent significant progress in the field. “They increase the safety and efficiency of hydrogen refueling and support the integration of hydrogen-powered vehicles into the market,” explains Bernhard Zemann, who coordinates HOERBIGER’s hydrogen activities.
