Energy Storage: The Parisian District Cooling System
Decoupling the energy use from the supply, cool storage systems integrated in district cooling allows significant reduction in installed cooling capacity (from 15% to 50%) and all auxiliary

Foundational to these efforts is the need to fully understand the current cost structure of energy storage technologies and identify the research and development opportunities that can impact
Cold storage technology is useful to alleviate the mismatch between the cold energy demand and supply. The integration of cold energy storage in cooling system is an effective

The price is the expected installed capital cost of an energy storage system. Because the capital cost of these systems will vary depending on the power (kW) and energy (kWh) rating of the system, a range of system prices is provided. 2. Evolving System Prices
We estimated the levelized cost of cooling as $5/MWh, significantly lower than $15/MWh for the base scenario where chillers and dry coolers supply the same cooling load without the RTES. We also estimated that the RTES-based cooling system annually avoids CO2 emissions up to 1488 tCO 2 e compared to the base case.
Generally speaking, the cost of the gas storage tank is the most expensive part of the entire system. Operation and maintenance costs include energy consumption and equipment maintenance. The current cost of compressed air energy storage systems is between US$500-1,000/kWh.
Cooling production, electricity consumption, and levelized costs of data center cooling system. Total CAPEX for the cooling systems was $1.41 million on average, and chillers in Scenario 1 had the highest CAPEX among the components (Fig. 7 (b)).
