Gloucester Coa has received planning approval from the New South Wales government for the 3.6GWh Stratford Pumped Hydro and Solar project.

The Nature Conservancy (TNC), Sun Tribe and ENGIE will deploy a solar and battery storage portfolio at former coal mine sites in the Appalachians, US.

The first pumped hydro energy storage (PHES) project to be built at a former coal mine in the US will receive up to US$81 million in Department of Energy (DOE) funding.

The German state of North-Rhine Westphalia looks set to go ahead with a 200MW pumped hydro energy storage project in a coal mine, as well as a smaller energy storage demonstration project which includes a flywheel from Stornetic.
