Viritech, a UK-based fuel cell technology developer, has initiated a study to explore the potential of hydrogen fuel cell range extenders (REX) for on-and-off highway electric vehicles. The project, backed by grants from the Department for Business and Trade, the Advanced Propulsion Centre, and the Niche Vehicle Network, aims to assess the feasibility of deploying portable fuel cells in niche vehicle mobility applications to meet regulatory standards and enhance automotive duty cycle requirements. While fuel cells have primarily been used in medium to heavy commercial vehicles as range extenders, Viritech sees a promising market in utilizing them for L-Cat vehicles to broaden their use cases and capabilities. Current challenges faced by battery electric last-mile delivery vehicles, such as limited range in extreme conditions and the need for larger batteries causing weight concerns, are areas where portable fuel cells could offer a solution. By integrating cost-effective fuel cells with existing battery packs, Viritech aims to pioneer a zero-emissions solution for niche vehicle mobility applications, thus contributing to the global transition towards zero-emissions transport. Viritech's CEO, Timothy Lyons, expressed enthusiasm for the project, emphasizing the importance of support from governmental and industry bodies in driving innovation in zero-emissions mobility. As part of the study, Viritech seeks collaboration with L-Cat vehicle manufacturers and last-mile delivery operators to tailor the fuel cell range extender powertrain to meet specific operational needs.
