Scientists at the #InternationalInstituteForAppliedSystemsAnalysis #IIASA in #Austria 🇦🇹 have developed a system to store renewable energy in abandoned mines‼️ The gravity based system lifts sand up the shaft during peak power times then slowly drops the mass during low energy times. A motor/generator,
⚡#RegenerativeBrake⚡ is used to control the mass, similar to what is now used in current #ElectricVehicle technology.
