Indian startup develops sand-based gravity energy storage system
Baud Resources, a cleantech start-up, has developed a gravity energy storage mechanism that uses locally available materials like sand and industrial waste as its payload. The company is expected to announce its inaugural commercial plant by the end of this year, with completion expected in 2025. The plant will have a 100 MWh capacity and offer a levelized cost of storage of around INR 2.5/kWh.
