ARENA Project Name: Renewable Hydrogen Demonstration for Heavy Transport
Ark Energy’s first hydrogen hub, called ‘SunHQ’, will be located within a major industrial precinct at the Sun Metals Zinc Refinery in Townsville, North Queensland.
Phase 1 of SunHQ will involve a 1MW PEM electrolyser, supplied by Plug Power, which will produce green hydrogen from a behind-the-meter connection to the co-located 124MWac Sun Metals solar farm. Compression, storage and refuelling facilities will be located adjacent to the electrolyser.
The initial demand use case will be five 140 tonne rated hydrogen fuel cell electric trucks (FCETs) which Ark Energy will source from Hyzon Motors and lease to its sister company Townsville Logistics Pty Ltd. The FCETs are expected to be the largest fuel cell trucks in the world. They will operate between the Sun Metals Zinc Refinery and the Port of Townsville, which is approximately a 30km round trip. The FCET’s will displace five existing diesel prime movers and avoid 1,300 tonnes of CO2 emissions every year.
Phase 1 of SunHQ will have a production capacity of 155,000kg p.a., which is in excess of the 91,250kg p.a. required by the five FCETs. Accordingly, there will be additional capacity for Ark Energy to supply green hydrogen to third-party customers and support their transition to a low carbon future.
Ark Energy has engaged GPA Engineering as its Owner’s Engineer on SunHQ.
2. Project Details
The key dates for Phase 1 of SunHQ include:
- Final Investment Decision: August 2021
- FCET Purchase Order: August 2021
- Electrolyser and Compression, Storage & Dispenser (CSD) Package Purchase Order: October 2021
- Site Commissioning: December 2022 (target)
The total cost of Phase 1 of SunHQ is A$13.1 million as at March 2022. SunHQ has received a A$5 million grant from the Queensland Government as well as a A$3.02 million grant from the Australian Renewable Energy Agency (ARENA). The Clean Energy Finance Corporation (CEFC) has committed up to A$12.5 million to support Ark Energy deliver SunHQ. SunHQ is the first hydrogen project to be jointly supported by ARENA and CEFC.
