Battery or Hydrogen – that is the question
In its mission to drive emissions down from the transport side of the coin, Auckland Transport is looking at both batteries and hydrogen technology. Battery technology is already in use with the Airport Link buses being fully electric. Hydrogen as a fuel is being trialled at port of Auckland and will be soon expanded in South Auckland.

Auckland Transport explores hydrogen refuelling solutions
Auckland Transport (AT) and Hiringa Energy Limited are looking at trialling hydrogen powered bus services – using a hydrogen refuelling facility being developed in south Auckland.
Through the development of the Low Emission Bus Roadmap, Auckland Transport has identified hydrogen as a potential energy storage and fuel for Auckland’s future low emission public transport fleet.
AT has been assessing hydrogen fuel cell (HFC) bus options to support the transition to zero emission buses and is a key partner of the hydrogen demonstration project with Ports of Auckland.
Auckland Mayor Phil Goff says, “transport makes up more than 40 per cent of Auckland’s emissions profile, so transitioning to low and zero-emissions vehicles is important to helping Auckland 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.”
AT’s Chief Executive Shane Ellison says there is a great benefit in exploring, with Hiringa, potential hydrogen refuelling solutions for low emission bus and ferry services using green hydrogen fuel.
“This would support our existing work with Ports of Auckland. Fuel cell buses meet the heavy daily demands of public transport. Hydrogen-powered buses and ferries would overcome the challenges of large and heavy battery packs on bigger buses and ferries. Hydrogen fuel offers far greater flexibility for public transport operators and will complement battery electric services.”
Andrew Clennett, Chief Executive Officer of Hiringa Energy, says his company is thrilled to be working with AT to ensure that all future buses are zero emission.
“We applaud AT’s forward thinking and approach to emissions reduction and look forward to working with the team to leverage our refuelling network and capability to ensure green hydrogen is available when needed.
‘We often see people expecting a two horse race between hydrogen and battery electric with only one winner. In reality it’s going to need a mix of both technologies, with each playing to its strength. That’s what we are seeing internationally and analysis for the New Zealand fleets suggests this is going to be the optimal approach.”
He says hydrogen performs most effectively for the higher use buses that need to stay on the road, providing a service day and night, and covering the most kilometres. These buses produce the most emissions in a diesel fleet, and hydrogen will help public transport operators rapidly decarbonise their fleets without compromising their existing service.
Auckland Transport will now focus on exploring hydrogen fuel cell (HFC) bus fleet deployment, with a selected bus operator contracted by Auckland Transport, under a new bus fleet ownership model incorporating hydrogen supply.
Future work will include investigating the potential supply of green hydrogen to support future hydrogen ferry services.

This video explains why AT is undertaking the hydrogen trials and leading the transition to this technology as part of the Low Emission Bus Roadmap:
In Australia, a new hydrogen research hub will be established in Victoria, bringing together research and industry to develop and demonstrate new hydrogen technologies, after securing a $10 million funding boost from the Victorian government.
What is not said is where the Hydrogen base is going in South Auckland as I am waiting for Auckland Transport to get back with an answer on that one. None-the-less let’s see where the trials will go.
