摘要:
Compressed CO2 energy storage is a reliable physical energy storage solution. The main challenge of compressed CO2 energy storage system is how to solve the high-density storage of low-pressure CO2. In this study, we proposed a new type of adsorption transcritical compressed CO2 energy storage system. We used adsorbents to adsorb CO2 for achieving low-pressure, high-density storage of low-pressure CO2. We investigated the gas storage capacity of the adsorption storage system and the heat and mass transfer process. Results demonstrate that the storage density (57.6 degrees C-25 degrees C) of adsorption gas storage is 43.46 kg/m3, which is 24.8 times of the CO2 density (1.75 kg/m3, 30 degrees C, 1 bar). If the adsorbents are heated above 160 degrees C, then the storage density will increase 3-4 times. The whole process is controlled by heat exchange efficiency. The heat exchange efficiency greatly affects the response time of the system during the application.
