The Enviro400FCEV, developed on the H2.0 platform, is ADL's next generation double deck hydrogen bus will deliver a zero-emission range of up to 300 miles. It will be powered by a Ballard fuel cell power module through the efficient Voith Electrical Drive System.

With hydrogen tanks and key components intelligently packaged by the engineers that developed the market’s widest range of clean buses, ADL’s next generation hydrogen bus is an integral vehicle design that perfectly balances weight and maximises saloon space.

Powered by a class-leading Ballard fuel cell power module, it continues ADL’s philosophy of working with only the best in their field. Specified to just the right power output, the fuel cells minimise fuel consumption and maximise performance for lowest total cost of ownership.

With fewer higher volume tanks, H2.0 reduces maintenance effort while increasing fuel capacity to deliver increased zero emission range.

H2.0 uses the latest technology in the form of the Voith Electrical Drive System. This boosts energy regeneration during the braking phase and delivers increased efficiency that is further enhanced by advanced thermal management which uses excess heat from the fuel cells and driveline to heat the saloon, minimising additional power requirement.
