Daimler Testing Fuel-Cell Truck with Liquid Hydrogen
Like other heavy commercial truck manufacturers, Daimler Truck is developing trucks that can utilise hydrogen for power. Since last year, a Mercedes-Benz GenH2 Truck fuel-cell prototype has been undergoing testing, and the company is now putting another prototype into operation to test the use of liquid hydrogen.
Daimler Truck says it prefers liquid hydrogen in the development of hydrogen-based drives. In this state, the company says it has a significantly higher energy density in relation to volume compared to gaseous hydrogen. As a result, more hydrogen can be carried, which significantly increases the range and enables comparable performance of the vehicle with that of a conventional diesel truck.
During the refuelling process, cryogenic liquid hydrogen at minus 253 degrees Celsius is filled into two 40 kg tanks mounted on either side of the chassis.
The development objective of the GenH2 Truck is a range of up to 1,000 kilometres and more, and Daimler says that series production for hydrogen-based trucks is planned for the second half of the decade.
