Abandoned underground mines could be repurposed to store vast amounts of energy using gravity batteries, according to an international team of researchers.
From Europe to North America, former coal mines are transforming into renewable energy storage sites. These abandoned shafts now serve as gravity batteries, storing excess energy by lifting and lowering heavy weights.

科学家估计,全球数百万个废弃矿井可改造为地下重力储能（UGES）系统,为能源存储提供新途径
A novel technique called Underground Gravity Energy Storage turns decommissioned mines into long-term energy storage solutions.
One innovative approach gaining traction is the revival of abandoned mines for modern energy storage.This concept not only addresses the challenges of energy intermittency but also repurposes defunct mining sites, contributing to sustainable development.
Abandoned mines promise revolutionary energy storage. The underground cavities that once symbolized industrial decline are now strategic resources for renewable energy infrastructures.
