Researchers at UC Riverside are testing a retrofitted Fiat Ducato van featuring a hydrogen internal combustion engine (H2-ICE). This project, supported by the Hydrogen Engine Alliance of North America, aims to evaluate the performance and emissions of hydrogen combustion as an alternative to battery-electric power for medium-duty and long-haul vehicles. While the engine technology is considered mature, the project highlights significant hurdles for U.S. adoption, specifically the lack of fueling infrastructure and the high cost of green hydrogen. The testing focuses on creating a pragmatic path toward decarbonizing commercial transportation and off-road equipment.
