9/ Key Findings: #India has 52 viable #SPHES sites totalling 587 GWh, mainly in Maharashtra, Goa & Karnataka. SPHES uses seawater—non-competing with freshwater, ideal for coastal energy storage. A key step toward sustainable, resilient energy systems #NetZero

3/ Novelties of research: presenting a globally replicable, #Python-based GIS model to identify & evaluate #PHES and #SPHES potential, including site mapping, cost estimation & scalability. #India is chosen as a case study to show its broad relevance & global adaptability.
