The 160MWh (megawatt hours) plant, installed in collaboration with Triveni Turbine Ltd and Energy Dome, Italy marks a landmark development in the domain of Long Duration Energy Storage (LDES).
- LDES store energy for extended periods of time ranging from 8 hours, to days, weeks, or seasons.
CO2 Battery Storage System
- About: It works by compressing and liquefying CO2 when energy is plentiful (charging phase) and expanding it back into gas to drive a turbine when energy is needed (discharging phase).
- Functioning: It functions on a ‘Closed Brayton Thermodynamic Cycle’, where the charging and discharging of electricity occur by manipulating the physical parameters of CO2 from vapor to liquid state.
- Comparison with other Battery Energy Storage Systems (BESS): Unlike BESS based on electrochemistry, it operates on specialized electro-mechanical turbomachinery.
- Hence having minimal performance degradation.
Energy Storge Systems
- About: They are used for storing excess energy during periods of low demand and releasing it when demand peaks.
- Significance: Provide a greener and sustainable energy environment, uphold the stability and reliability of grid.
- Major types of Energy Storage Systems
- Chemical Energy Storage Systems: Store chemical energy and convert it to electrical energy using electrochemical reactions. E.g., Lithium- Ion Batteries, Sodium- Ion Batteries, etc.
- Advanced Chemical Energy Storage System: New generation of chemical batteries that are more efficient, durable, and environmentally friendly than traditional batteries. E.g., Co2 Batteries, etc.
- Thermal Energy Storage System: They store thermal energy by heating or cooling a storage medium to be used at a later time. E.g., Electric Thermal Energy Storage, etc.
