IIASA-led study proposes Underground Gravity Energy Storage as long-term energy storage solution for renewables

Green Car Congress

However, because sunshine and wind are inherently variable and inconsistent, finding ways to store energy in an accessible and efficient way is crucial. While there are many effective solutions for daily energy storage, the most common being batteries, a cost-effective long-term solution is still lacking. Dabek, P.B.,
