India Invites Proposals for Gravity-Based Energy Storage Projects, an Industrial Info Market Brief

India's Ministry of New and Renewable Energy has invited research proposals on gravity-storage systems to be installed in the country. With an increasing share of renewables in the energy mix, India would need energy storage for absorbing fluctuations and for grid balancing. This technology is based on the simple principle of raising and lowering a heavy weight to store energy. In gravity-based energy storage systems, electricity is used to lift mass to higher elevation, thereby storing potential energy. Lowering this mass discharges energy, which can again be converted into electricity.
