Transdev in New Zealand explores new hydrogen tech to reduce emissions


In efforts to reduce its carbon footprint Transdev subsidiaries Howick and Eastern Buses in Auckland and Mana Newlands Coach Services in Wellington, has committed to trial a new hydrogen fuel technology in its existing diesel bus fleet.

Greg Pollock, Chief Officer and Managing Director of Transdev New Zealand said trials would soon commence using the new HYDI Hydrogen fuel system which has been designed to fit a standard diesel bus, adding hydrogen gas to a diesel engine.

“A HYDI Hydrogen unit will soon be fitted to buses in our Wellington fleet, with the goal of testing to determine what level of reduced fuel consumption and ensuing emissions we can achieve in Wellington conditions,” Greg Pollock said.

“Globally, transport accounts for more than 24 percent of total CO2 emissions yearly, which is why we are exploring more electric and hydrogen fuel technologies to reduce our environmental impact and meet New Zealand Government’s emissions reduction targets.”

The technology being deployed is developed by South Australian company HYDI Hydrogen.

Managing Director of HYDI, John Wilson, said independent testing of the HYDI Hydrogen on demand system at the University of South Australia had shown an 80 percent reduction in carbon emissions when fitted to a diesel engine.

“Analysis of the exhaust gas of a bus fitted with the HYDI Hydrogen system showed significant reductions in greenhouse gases, including carbon,” John Wilson said.

“While there is much attention on future fleet technologies, there is usually substantial investment and long lead times required in delivering new fleet, remembering that heavy vehicles, such as buses, have a life cycle of 20 years or more.”

Greg Pollock agreed, saying the need for action was immediate.

“Transdev continues to work proactively with governments and partners to build more sustainable future fleets, at the same time we are also taking steps to make immediate reductions to vehicle emissions in our fleet,” he said.

Transdev will trial the HYDI Hydrogen system in its bus operations locally in Wellington before assessing the suitability for other sites.
