Symbio, a joint venture involving Forvia, Michelin, and Stellantis, revealed its hydrogen-powered heavy-duty truck at the ACT Expo held in Las Vegas, Nevada. The regional haul Class 8 truck, named 'H2 Central Valley Express,' is part of a project to develop a hydrogen fuel cell truck matching the performance of a diesel truck but with zero emissions. Powered by Symbio's 400 kW StackPack fuel cell system, the truck replaces the diesel engine with a hydrogen fuel cell powertrain designed for long-haul operations. The vehicle, integrated into a Freightliner Cascadia Class 8 tractor, boasts a 70-kg hydrogen tank and a range of over 450 miles per fueling event. One of the key features of this project is the use of low-rolling resistance tires from Michelin, specifically designed for hydrogen trucks, which are being tested to gather data for further improvements. The truck is set to hit the roads for a 12-month demonstration on a 400-mile route in California, running between the Inland Empire and Northern San Joaquin Valley. The demonstration will include tests on various challenging operating sections to evaluate the truck's performance in different conditions.
