German Creek Waste Coal Mine Gas Power Station

German Creek Waste Coal Mine Gas Power Station is a transitioning coal mine waste gas project located approximately 25km southwest of Middlemount in the Bowen Basin region of Central Queensland. It was registered in December 2021 by the project proponent, EDL CSM (Qld) Pty Ltd, and covers an unknown area. The project sits within a landscape heavily characterised by open-cut and underground coal mining, though the broader regional land use also includes cattle grazing and grain crop farming.

Coal mine waste gas projects involve capturing and combusting waste coal mine gas (primarily methane) that is released during the coal extraction process. Standard requirements under this methodology involve actively extracting the gas through mine ventilation and coal seam drainage, and then destroying it through combustion to displace grid electricity or flaring. This prevents the methane, which is a potent greenhouse gas and severe safety hazard, from being vented directly into the atmosphere.

The Middlemount environment experiences a moderately dry, summer-dominant rainfall pattern, averaging around 568mm of precipitation annually. The regional soils are typically clay-heavy, often exhibiting high pH and sodicity, alongside yellow duplex soils with sandy loam or loam surfaces.

This project transitioned into the ACCU scheme as a displacement electricity production project involving the operation of former Renewable Energy Target (RET) electricity production devices. Operating at the German Creek Mine, EDL uses the captured methane to fuel a 38 MW power station, producing reliable electricity for the national grid. The facility has been a massive supplier of carbon abatement; it was recorded as the single largest ACCU generator in December 2024, receiving over 73,000 units in that month alone. However, it has also drawn some scrutiny from environmental groups, as methane plumes have occasionally been detected from space near the broader facility footprint.
