Auckland Transport Sets the Groundwork for New Zealand’s First Hydrogen Bus

01 Mar 2021  by Stephen Forbes   

Auckland Transport (AT) is getting set to unveil the country’s first hydrogen fuel cell bus this month as it moves towards an emission-free fleet by 2040.

The country's first hydrogen fuel cell bus which is expected to be officially unveiled this month.

And AT chief executive Shane Ellison said the technology will give public transport operators more flexibility and complement existing electric bus services.

The $1.175m bus, which was built by Global Bus Ventures (GBV) in Christchurch, will run between Howick and Britomart and will be operated by transport operator Howick and Eastern for the initial trial.

It will use a hydrogen fuel cell to generate electricity along with batteries and the only byproducts produced will be water, electricity and heat.

Fuel cell electric buses are already commonplace in a number of European cities, including Stuttgart, Cologne, Frankfurt, Hamburg, Versailles and Rotterdam.

AT is looking at replacing the supercity’s existing diesel buses with both electric and hydrogen fuel cell vehicles which are expected to cost between $150 and $200 million.

And it is also in talks with Taranaki-based Hiringa Energy Limited about building a hydrogen refuelling facility in south Auckland.

Ellison said the hydrogen fuel cell technology would allow its buses to travel further than current electric vehicles on some of the city’s longer routes before refuelling.

The capacity of the electricity network to handle both the increased use of electric buses and private electric vehicles was also another consideration. He said the use of hydrogen buses would help reduce demand for electricity.

He said, while it’s still early days, AT may end up opting for a mix of both electric and hydrogen fuel cell buses on Auckland’s streets.

Hydrogen fuel offers far greater flexibility for public transport operators and will complement battery electric services.

“They are all factors that are at play at the moment and why this trial is really important.”

Ellison conceded there are other countries around the world that have gone much further down the path of using hydrogen fuel cell buses and emission-free public transport.

“It obviously takes a lot of political commitment and those cities where it has been adopted there has been a huge commitment made to tackling climate change,” Ellison said. “But if you compare us with Australian cities we’re doing pretty well.”

In a statement Auckland Mayor Phil Goff said the fact transport makes up more than 40 per cent of Auckland’s emissions means transitioning to low and zero-emissions vehicles is important to help the city achieve its climate change goals.

“With the right infrastructure, hydrogen has the potential to power our buses and other parts of our vehicle fleet, which will help reduce emissions and lower air pollution in Auckland.”

Matt Lowrie is the editor of transport and urban design blog Greater Auckland. He said the biggest hurdle in changing the city’s bus fleet to more environmentally sound options is the upfront cost.

“They have lower operating costs, but they still take some time to pay for themselves,” Lowrie said.

He said New Zealand has been behind other countries in adopting emission-free public transport buses. And he said that is partly due to funding.

Lowrie said most of Auckland’s bus fleet was replaced between 2015 and 2018 and involved buying new diesel buses at the time. But things have changed markedly since then, both locally and internationally.

“As part of those contracts AT didn’t require operators to have electric and emissions free buses. And it was probably a year or two before electric buses became more mainstream,” Lowrie said.

“But by the end of the decade those buses will be coming to the end of their useful lives.”

And he said hydrogen fuel cell technology is an option.

“We need zero emissions buses as soon as possible,” Lowrie said. “There’s lots of technology out there and I think AT is trying to find the right one going forward.”
