One promising option is to turn old fossil power plants into battery storage sites. Renewable energy sources like wind and solar are the mainstay of the net-zero transition. They don't emit greenhouse gases, so the more they replace fossil fuels like coal and gas the closer we come to net-zero emissions.

Energy storage involves converting energy from forms that are difficult to store to more conveniently or economically storable forms. Some technologies provide short-term energy storage, while others can endure for much longer. Bulk energy storage is currently dominated by hydroelectric dams, both conventional as well as pumped.

A company called Energy Vault has since replaced it with the Reid Gardner Battery Energy Storage System, which has a capacity of 220 megawatts. The site came online in late April 2024. The more projects like these come online, the better they will become, argues Donald. "It's obviously an emerging technology," she says.
An international team of scientists recently proposed another innovative and resourceful solution that involves repurposing old mines: Underground Gravity Energy Storage (UGES). They outlined the idea in the journal Energies. UGES involves lowering large amounts of sand stored in containers attached to a central cable down a deep underground shaft.
One of Europe''s deepest mines is being transformed into an underground energy store. It will use gravity to retain excess power for when it is needed.
