In partnership with Michelin, Symbio (here’s some info about the company) launches at ACT Expo 2024 its first Hydrogen Fuel-Cell heavy-duty truck to demonstrate the performance and reliability of zero-emission fuel cell technology for demanding heavy-duty transportation.

Symbio has designed, developed, and integrated a heavy-duty long-haul truck ready fuel cell powertrain, powered by Symbio’s fuel cell technology, into a Freightliner Cascadia class-8 tractor. The diesel engine has been replaced with Symbio’s 400 kW StackPack fuel cell system consisting of four packaged sub-systems of Symbio’s proprietary stack technology proven in the field with more than 5 million miles (8 million km) on-road experience.

The heavy duty 400kW power system’s control strategy is optimized to deliver superior energy balance and power, meeting the functional requirements of the diesel truck. With a 70kg hydrogen tank onboard, the fuel cell truck is capable of over 450 miles per fueling event. Michelin (co-shareholder of Symbio) provides next generation low-rolling resistance tires that combine safety, longevity and improved fuel efficiency, thus enhancing the total cost of ownership of the vehicle.

Expected to hit the road by the end of 2024, the truck will run for 12 months on a challenging 400-mile (650 km) route between the Inland Empire and Northern San Joaquin Valley. “We are thrilled to present the cutting-edge, innovative Symbio’s 400 kW heavy duty fuel cell stack that enables a significant engine weight reduction without compromise on performance. This hydrogen-powered class-8 fuel cell truck is testimonial of Symbio’s fuel cell technology leadership and system integration know-how,” said Rob Del Core, General Manager, Symbio North America.

“Hydrogen plays a key role in Michelin’s all-sustainable approach and Symbio brings us with this announcement one step closer to becoming a world leader in hydrogen systems for mobility,” added Alexis Garcin, President and CEO, Michelin North America, Inc. “Equipped with Michelin low rolling resistance Tires and with the Symbio Hydrogen fuel cells, this breakthrough will accelerate the transition to a greener long haul transportation with extended range and fast charging time”.
