ADL H2.0: Fuel-Cell Double-Decker Achieves Almost 500 Kilometers

The British bus manufacturer Alexander Dennis Limited (ADL), a subsidiary of the North American NFI Group Inc., has introduced the next generation of its double-decker hydrogen buses under the project name H2.0. It is expected to hit the road by the end of the year and boasts a range of up to 480 km. It is powered by a Ballard fuel cell integrated into the Voith Electrical Drive System (VEDS).

Fewer Tanks, Higher Volume

In the H2.0, insights from nationwide tests have been incorporated along with the 25 years of hydrogen experience from New Flyer, another subsidiary of the NFI Group and a pioneer in fuel cell buses. With a reduced number of tanks but a larger volume, the vehicle concept reduces maintenance efforts while increasing fuel capacity to achieve a greater range.

Utilize Excess Heat

Additionally, the H2.0 takes advantage of Voith's electric drive system. This maximizes energy recovery during recuperation and ensures increased efficiency, further enhanced by innovative thermal management. The excess heat from the fuel cells and drivetrain is used to heat the passenger compartment, minimizing the power draw from the batteries.

"The H2.0 will be a milestone for zero-emission technology – with unmatched efficiency and top-range performance. It is perfectly suited for high-mileage routes not covered by battery technology." (ADL President and Managing Director Paul Davies)
