Prototype Thermochemical Energy Storage System

Large quantities of thermal energy – both per weight and price - can be stored reversibly in many salts upon ab-/desorption of water or ammonia. Vast efforts are being made to achieve cost-competitiveness with other forms of energy storage technologies. In this work, Thermochemical Energy Storage (TCS), which stores. . Lawrence Berkeley National Laboratory, NETEnergy LLC, National Renewable Energy Laboratory, UC Berkeley. Such thermochemical heat storage has an energy storage density up to 10 times higher than water (depending on the thermochemical material used), with the addi-tional. . CaCO3/CaO thermochemical energy storage (TCES) system has a high heat storage density (1780 kJ/kg) along with high heat storage and release temperature (650–850 °C), which can be applied to concentrated solar power (CSP) technology utilizing CO2 Brayton cycles to improve power generation. .
