ARENA has conditionally approved $3.02 million in funding to Ark Energy to support the SunHQ Hydrogen Hub project, with the project also supported by $12.5 million debt finance from the Clean Energy Finance Corporation. The Queensland Government’s Hydrogen Industry Development Fund will also contribute $5 million.

Phase 1 of the SunHQ Hydrogen Hub (SunHQ) will deploy a 1 MW PEM electrolyser, installed at the Sun Metals' refinery, powered by electricity from the existing 124 MW solar farm. The electrolyser will produce renewable hydrogen to fuel five ultra-heavy 140 tonne rated fuel cell electric trucks.

This is a first-of-a-kind deployment for Australia and will help to reduce emissions in the ultra-heavy transport sector.
