Energie opslag a la een klassieke staande klok met gewichten, maar dan in het groot.
“A new prototype gravity-based energy storage system is in the works, promising to store energy at half the price of current market-leading lithium-ion (Li-ion) batteries — with tests beginning next spring, in Scotland, according to the company website.
Gravity-based energy storage beats lithium-ion batteries
Based in Edinburgh, Gravitricity’s concept is to raise weights of roughly 13,227 tons (12,000 tonnes) up into a lattice tower, and then release them into a deep shaft — releasing and discharging potential energy according to how much is needed.
A Dutch winch specialist Huisman, along with a UK engineering firm Kelvin Power, is building the 250 kW version of the concept — as part of a $1.3-million (£1 million) project, reports Recharge News.”
