The ADAC Nurburgring 24 Hours, set to run Sunday through Monday, will mark the debut of the first hybrid hydrogen-powered racecar to compete in an international motorsports event. Technology company The Linde Group will be responsible for refueling the specially equipped Aston Martin Rapide S with hydrogen at the racetrack.
Linde has developed a mobile hydrogen refueling unit (ABOVE) suited for locations without a stationary hydrogen infrastructure. The 46-ft-long truck and trailer unit trailH2-gas is equipped with two separate high-pressure couplings for gaseous hydrogen (CGH2) and stores the gas at 300 and 450 bar in cylinder packs. The trailH2-gasTM can further compress the hydrogen on-board to reach pressures of up to 700 bar, depending on requirements. For this project, however, a pressure of 350 bar is needed.
For racing purposes, the usual automated refueling procedure, which takes a few minutes, will be replaced by a manual, supervised refill, reducing the necessary stopover to less than a minute.
