RHeaDHy Project Advances Hydrogen Refueling for Heavy-Duty Vehicles

In Grenoble, HRS, alongside Toyota Motor Europe and ENGIE Lab CRIGEN, successfully completed extensive testing of Twin Nozzle hydrogen refueling technology for heavy-duty mobility. This initiative seeks to align hydrogen refueling speed with diesel, enhancing efficiency for trucks.

Over six days, 18 tests validated the Mid Flow Twin technology in various conditions, such as temperatures from 15°C to 40°C and tank pressures between 60 to 300 bar. Notably, at 30°C, a full refuel took just six minutes, extending driving range up to 600 km. Over 400 kg of hydrogen were used, fully recycled post-tests.

The campaign confirmed the robustness of the ISO 19885-3 protocol, achieving over 95% state-of-charge even at high temperatures. This marks a vital step toward fast, reliable hydrogen solutions for heavy-duty applications.
