Project description

Emerald Coaches is a regional transport service based in Emerald and Mackay, Queensland. It operates a fleet of over 120 vehicles, supplying passenger transport services to the mining and resources sector as well as charter and school transport services.

Emerald Coaches diesel-powered fleet presently consumes over one million litres of fuel annually, producing 3,100 tonnes of greenhouse gas (GHG) emissions.

Emerald Coaches is implementing an eMission zero project, under which its full fleet of vehicles would be replaced by HFCE vehicles by 2040.  It is anticipated that the first two vehicles would be introduced during 2024.

Offtake options for renewables-based hydrogen are under investigation, including electrolyser-based production at Emerald Coaches depot in Emerald, Central Queensland.

Emerald Coaches’ estimates that full conversion of its vehicle fleet by 2040, including associated hydrogen production and refuelling infrastructure, would cost an estimated AUD$100 million.

In April 2022, it was announced that the project was awarded AUD$2.7 million in support through a grant from Round Two of the Queensland Government’s Hydrogen Industry Development Fund (HIDF).
