"An abandoned mine in Finland is set to be transformed into a giant battery to
store renewable energy during periods of excess production.
The Pyhäsalmi Mine, roughly 450 kilometres north of Helsinki, is Europe’s
deepest zinc and copper mine and holds the potential to store up to 2 MW of
energy within its 1,400-metre-deep shafts.
The disused mine will be fitted with a gravity battery, which uses excess
energy from renewable sources like solar and wind in order to lift a heavy
weight. During periods of low production, the weight is released and used to
power a turbine as it drops.
The gravity battery system has been developed by Scottish firm Gravitricity,
which plans to use the Finnish mine as a full-scale prototype to demonstrate
the technology.
“This project will demonstrate at full scale how our technology can offer
reliable long-life energy storage that can capture and store energy during
periods of low demand and release it rapidly when required,” said Martin
Wright, an executive chairman at Gravitricity.
“This full-scale project will provide a pathway to other commercial projects
and allow our solution to be embedded into mine decommissioning activities,
offering a potential future for mines approaching the end of their original
service life.”
A study last year by the International Institute for Applied Systems Analysis
(IIASA) estimated that gravity batteries in abandoned underground mines could
store up to 70TWh of energy – enough to meet global electricity demands.
The repurposed mines could also provide economic benefits to the communities
that previously relied on the mine for their livelihoods."
