A large-scale energy storage project using liquid CO2 technology developed by Energy Dome. The system stores electricity by compressing and liquefying CO2 when there is excess energy and generates electricity by expanding the CO2 through a turbine when needed. The plant delivers 20 MW power and 200 MWh energy, equivalent to 10 hours of continuous discharge, and is the first full-scale commercial u
