Major power firm EnergyAustralia is studying the feasibility of building a huge pumped hydroelectric energy storage project in the Spencer Gulf of South Australia.
The cost of lithium-ion batteries for energy storage declined 65% in five years between 2010 and 2015, while battery storage’s use for electricity could hit 250GW by 2030, from just 1GW today, according to the International Renewable Energy Agency (IRENA).
US-based power firm Duke Energy plans to increase the energy storage capacity of its Bad Creek pumped storage hydroelectric station by 200MW between the years 2021 and 2024.
The organisers of luxury sporting estate Eishken are planning to install 300MW of pumped hydro storage (PSH) on the Scottish Isle of Lewis to store energy primarily from wind farms on the island.
