Researchers May Have Found a Way to Store Energy Using Abandoned Mines
A team made up of researchers from all over the world has developed a new way to store energy by lowering sand into defunct underground mines. The novel technique, called Underground Gravity Energy Storage (UGES), presents an effective long-term solution to store energy that makes use of abandoned mining sites. The researchers stated that the technique could be used when the price of electricity was high. The approach involves transporting sand into underground mines and then converting the soil’s potential energy into electricity through regenerative braking. The researchers explained that when electricity was cheap, the soil could then be removed…
