Auckland Transport (AT) is preparing to unveil New Zealand’s first hydrogen fuel cell bus this month, as it moves towards an emission-free fleet by 2040, Stuff reports. According to AT Chief Executive Shane Ellison, the technology will give public transport operators more flexibility as well as complement existing electric bus services. The $1.175m bus, built by Global Bus Ventures (GBV) in Christchurch, will run between Howick and Britomart. It will be operated by transport operator Howick and Eastern for the initial trial, and will use a hydrogen fuel cell to generate electricity, along with batteries. The only byproducts produced will be water, electricity and heat.
