Phase 1 of the SunHQ hydrogen hub (SunHQ) Renewable Hydrogen Demonstration for Heavy Transport project will deploy a 1 MW PEM electrolyser that will produce renewable hydrogen to fuel five ultra-heavy 140 tonne rated fuel cell electric trucks.
Heavy vehicles make up approximately 4 percent of road vehicles in Australia, but account for around 23 percent of all road transport fuel consumed. Replacing diesel vehicles with renewable hydrogen alternatives is viewed as a key opportunity for early uptake of commercially viable hydrogen due to the relatively high cost of diesel as the incumbent fuel.
This is a first-of-a-kind deployment for Australia and will help to reduce emissions in the ultra-heavy transport sector. The project will be located at the Sun Metals zinc refinery in Townsville, which is owned by Ark Energy’s sister company, Sun Metals Corporation (SMC).
Ark Energy and SMC are subsidiaries of Korea Zinc Company Limited (Korea Zinc), the largest zinc, lead and silver producer in the world. The project is part of Korea Zinc’s long-term strategy to export renewable hydrogen to supply Korea Zinc’s global operations as well as other end users in Asia, however the group’s priority is to build the domestic hydrogen economy of North Queensland first.
As part of the project, Ark Energy will:
- Install and commission a 1 MW PEM electrolyser which will be powered by the 124 MWac Sun Metals solar farm, which is co-located with the zinc refinery and SunHQ.
- Install refuelling infrastructure at SunHQ including compressors, storage, and dispensers.
- Take delivery of, commission and own five ultra-heavy 140 tonne rated fuel cell electric trucks supplied by Hyzon Motors to replace their equivalent diesel-powered trucks.
The trucks are expected to be the largest road-going fuel cell electric trucks in the world at the time of their deployment. Ark Energy will lease the vehicles to its sister company, Townsville Logistics (TL), which will operate them in road train triple trailer configuration and incorporate them into its short haul fleet currently transporting zinc concentrate and ingots between the Port of Townsville and the Sun Metals zinc refinery. The five zero emission vehicles will replace their equivalent diesel-powered vehicles and avoid 1,300 tonnes of CO2 emissions each year.
A new wave of zero emissions vehicles is harnessing power from the sun and wind to deliver electrifying performance.
