ADL announces next gen hydrogen decker – H2.0

Alexander Dennis Ltd (ADL) has announced its 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 Voith Electrical Drive System (VEDS).

Designed and fully built in Britain, ADL’s next generation hydrogen double-decker is being developed under the project name H2.0 and is expected to be on the road before the end of the year. ADL says the new bus 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 nationwide trials to set new standards for range and efficiency. It builds on more than 25 years of hydrogen experience of New Flyer, which is also part of ADL’s parent company NFI Group, and is considered one of the global pioneers in hydrogen buses.

The integral vehicle’s hydrogen tanks and key components are intelligently packaged by the engineers that developed the company’s wider range of clean buses. The design focuses on balancing weight and maximising saloon space.

The Ballard fuel cell power module is specified to just the right power output. The fuel cells are designed to minimise fuel consumption and maximise performance for lowest total cost of ownership. With fewer higher volume tanks, H2.0 should reduce 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.

ADL President & Managing Director, Paul Davies, said: “H2.0 is going to be a milestone for zero-emission technology with unrivalled efficiency that gives a class-leading range, perfect for high-mileage routes that battery technology doesn’t cover.

“Designed and built in Britain, our next generation hydrogen bus will retain investment in our economy and boost skills in clean vehicle technology, a crucial sector for future development as the United Kingdom targets net zero by 2050.”
