Cold Thermal Energy Storage System

About Cold Thermal Energy Storage System

Combined Heat and Power (Cogeneration) system is considered to be effective means for energy saving.
However, combined heat and power (cogeneration) system needs to utilize the heat and power simultaneously produced effectively as far as possible.
Steam-injection variable combined heat and power (cogeneration) based on gas turbine is one of the means to fully utilize the heat by converting from thermal energy to electric energy. This CHP(COGEN) system is known as heat utilization method for utilization of excess heat (thermal energy) while generating electric power.
Thermal storage system is known as a time-shift method to save excess heat (thermal energy) for the usage of heat during power shortages.
Thermal storage system is constituted of steam accumulator which has function to store heat (thermal energy) as steam, heat (thermal energy) storage tank which has function to store thermay energy as hot water , and cold thermal energy storage tank which has function to store cold thermal energy as cold water and ice. Combination of combined heat and power (cogeneration) and cold thermal energy storage system enable effective thermal energy utilization.
IHI offers and proposes customized energy system including cold thermal storage system facility.
