Alexander Dennis Limited (ADL) has claimed that its next generation double deck hydrogen bus will deliver a zero-emission range of up to 482 km (300 miles).
It will be powered by a Ballard fuel cell power module through the efficient Voith Electrical Drive System (VEDS).
This hydrogen double decker is being developed under the project name H2.0 and is expected to be on the road before the end of 2021.
ADL says it also supports the development of skills in the growing clean vehicle technology sector and boosts the UK hydrogen economy, while delivering governments’ net zero targets through the carbon-neutral electrification of high-mileage bus routes.
H2.0 is ADL’s second-generation hydrogen platform, incorporating learnings from UK trials to set new standards for range and efficiency.
With hydrogen tanks and key components intelligently packaged by the engineers that developed the market’s widest range of clean buses, ADL says its next generation hydrogen bus is an integral vehicle design that perfectly balances weight and maximises saloon space.
Powered by a Ballard fuel cell power module, and 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.
