Accelera by Cummins has made headlines by setting a new Guinness World Record for the longest distance traveled by a hydrogen fuel cell electric heavy-duty truck without refueling. This milestone was achieved by the hydrogen-powered H2Rescue truck, a Kenworth T370 prototype, which completed a remarkable 1,806-mile journey in central California on a single fill. The successful demonstration highlighted the potential of zero-emissions hydrogen technology for heavy-duty applications. Equipped with a 250kW traction motor and powered by Accelera’s fuel cell engine, the H2Rescue consumed 168 kilograms of hydrogen during the journey, emitting zero carbon emissions compared to a conventional diesel truck. The collaboration involving Accelera, the U.S. Department of Homeland Security’s Science and Technology Directorate, the U.S. Department of Energy, and the U.S. Department of Defense played a crucial role in developing this innovative vehicle. The H2Rescue truck, weighing 33,000 pounds, can power Federal Emergency Management Agency trailers and emergency shelters for up to 72 hours without refueling, making it a valuable asset for disaster relief efforts. Additionally, the fuel cell-powered truck can displace approximately 1,825 gallons of fuel annually and reduce greenhouse gas emissions by an estimated 2.5 metric tons, showcasing the environmental benefits of hydrogen technology in transportation. This achievement marks a significant step forward in promoting hydrogen as a feasible and sustainable fuel for heavy-duty vehicles, emphasizing its potential to contribute to a cleaner and greener future.
