Reducing Emissions through Gas-to-Energy Initiative
GHG Emissions
Mandalong, an underground coal mine in Australia, is characterized by its complex and large-scale emissions profile. These emissions mainly come from three ventilation fans that expel air from the mine. This air carries gases released from the coal extraction process and older, sealed areas. To manage inseam gas content, the site uses a gas drainage system, which plays a crucial role in maintaining mine safety and production efficiency.
Since 2014, Mandalong has operated a flare plant with two flares to burn off excess gases and an overpressure freevent stack for safety. Building on this foundation, in September 2023, a new 8MW power station, owned by EDL, was commissioned. This facility utilizes gas from the drainage system to generate electricity for the mine, with surplus power fed into the local grid. This initiative not only reduces Scope 1 emissions and improves environmental performance but also benefits local communities and businesses.
