NFI Group Inc., through its subsidiary New Flyer of America Inc., has introduced an optional four-tank hydrogen module for its Xcelsior CHARGE FC 40-foot fuel cell-electric bus (FCEB). The added tanks increase onboard hydrogen storage by 17.5 kilograms, expanding total fuel capacity and extending vehicle range by up to 120 miles.
The expanded fuel system is already in use by Humboldt Transit Authority in Northern California. The agency was among the first to operate the extended-range model in regular service, including on steep and demanding routes. The configuration has demonstrated improved operational flexibility and reliability in early field deployment.
The new tank module supplements the bus’s standard five-tank system, resulting in approximately 50% more fuel capacity. This allows transit agencies to cover longer routes, reduce refueling frequency, and adapt to more intensive duty cycles. The additional storage supports agencies operating in areas with fewer hydrogen refueling stations or more variable terrain.
Hydrogen fuel cell technology plays a key role in the decarbonization of transit, offering long range, short refueling times, and consistent performance in varied climates and topographies. Unlike battery-electric buses, which may face limitations in extreme conditions or long-route service, fuel cell buses provide a scalable option for agencies transitioning to zero-emission fleets without compromising operational coverage.
The latest version of the Xcelsior CHARGE FC also includes a lighter, high-efficiency fuel cell power module, improved waterproof battery enclosures, recyclable battery systems, and an electric drive system capable of up to 90% energy recovery.
This configuration is part of ongoing efforts to align zero-emission transit vehicles with the performance and reliability expectations of traditional diesel or hybrid fleets, particularly in regions with long service routes or limited charging and fueling infrastructure.
