Laxenburg (energate) - An international team of researchers led by Austria's International Institute for Applied Systems Analysis (IIASA) is developing a novel method for storing energy by transporting sand in abandoned underground mines. The new technique, called Underground Gravity Energy Storage (Uges), offers an effective solution for long-term energy storage, IIASA said. At the same time, it makes use of abandoned mining sites, of which there are probably several millio ...
