Coal mines may turn into ‘green hotspots’

Bloomberg

Australia is studying plans to transform a disused underground coal mine into a pumped hydro facility, part of a wider effort to reuse retiring fossil fuel sites for renewable energy generation.
The A$13 million ($9.9 million) pilot trial at the Newstan Colliery, in Fassifern, about 140 kilometres (87 miles) northeast of Sydney, could offer a blueprint for dozens of expiring mines that’ll be retired in coming decades, according to the Australian Renewable Energy Agency.
Studies will test whether the Centennial Coal Co site, close to
Lake Macquarie, can eventually support a 600-megawatt pumped hydro facility that would take advantage of its reservoir, grid connection and available water source. The results will also show if similar brownfield sites, including other coal operations, could also host renewables, ARENA said in a statement.
“By repurposing old sites and taking advantage of the features at those facilities, we can bring more clean energy projects online that bring down emissions and deliver the secure and reliable power Australians need,” Australia’s Energy and Emissions Reduction Minister Angus Taylor said.
