Owing to massive cost reductions, Li-ion technology is now leading lead-acid batteries in the power storage category; it is even challenging sodium sulphur and flow for long-duration storage. IHS estimates that 90 percent of the utility-side of meter energy storage projects tracked are based on Li-ion battery technology. Underpinning the rapid cost reduction is the build-up of the supply chain for batteries in the auto and power sectors. Competition between China’s BYD, GCL, South Korea’s Samsung SDI, LG Chem and Japan’s Panasonic is intensifying. In the residential space GCL has launched a battery system at $450/kWh (excluding inverter) in Australia, nearly matching Tesla’s announced price of $3,000 for a 7kWh system.
