PHES: A Multi-functional and Cost-Effective Energy Storage System

PHES: A Multifunctional and Cost-Effective Energy Storage SystemHanumanth Raju GV

India has set some ambitious renewable energy (RE) targets for itself — 175 GW by 2022 and 450 GW by 2030. This assigns an important role to grid-scale energy storage systems (ESS) for enabling smooth integration of RE into the grid to assure stability and round-the-clock electricity supply to the downstream consumers.The prominent ESS include pumped-hydro energy storage (PHES), compr
