The new refueller will replace an existing hydrogen refuelling station, which has been operational since 2014 and has served both Hyundai and competitor fuel-cell electric vehicles and hydrogen forklifts.
Hyundai said the upgraded facility will allow it to support the company's expanding range of HFCV through faster refuelling and through green hydrogen being generated on site.
The facility will feature an integrated electrolyser that will produce up to 20kg per day, as well as providing 700bar refuelling capability.
"This investment forms part of Hyundai's long-term commitment to a zero-emission future for Australia. Hydrogen fuel cell mobility is anticipated to play an integral role in the country's transition to cleaner drivetrains and we intend to help lay the stepping stones toward making this vision a reality," Hyundai Australia CEO Ted Lee said.
The car giant is pitching its NEXO FCEV against its Japanese rival Toyota's Mirai.
Hyundai said the refuelling station could fill up a NEXO in less than 5 minutes and allow it to travel up to 666km.
The company has selected US-based PDC Machines and IVYS Energy Solutions to supply the hydrogen refuelling station, known as the SimpleFuelFast, with ENGV responsible for local integration, installation and ongoing operational services.
Last year ENGV, PDC Machines and IVYS Energy Solutions joined forces with the CSIRO to form the Victorian Hydrogen Hub, which is currently under construction.
ENGV CEO Sean Blythe said Hyundai's project will leverage the experience gained through the CSIRO project as well as the company's delivery of the first public hydrogen refuelling station, commissioned by the ACT Government in Canberra.
"We are excited to bring our hands-on experience developing hydrogen refuelling infrastructure across Australia to the HMCA project. Together with Hyundai, we are committed to growing the country's hydrogen sector in a safe and sustainable way," he said.
Hyuandai says it anticipates a growing market for its advanced hydrogen technologies in Australia, including passenger and commercial vehicles as well as stationary power applications.
