Recently, Shijiazhuang Anrico Gas Machinery Co., Ltd., a subsidiary of CIMC Anrico, successfully put into operation several sets of specialized equipment for carbon dioxide energy storage, which were developed specifically for the first such demonstration project built in China by its client, Baiyang New Energy Technology (Shenzhen) Co., Ltd. On August 25th, these devices began to be used, marking a significant advance in the use of pressure vessels manufactured by this company in the field of new energy storage technologies. The reporter learned that CIMC AERIKO Holdings Co., Ltd. is one of the subsidiaries of CIMC Group, which is headquartered in Shenzhen. Carbon dioxide energy storage systems utilize the property that carbon dioxide can expand dramatically when it changes from a liquid state to a gas state, expanding by nearly 400 times at room temperature. The basic principle is to use excess electricity during off-peak hours to compress carbon dioxide gas at normal temperature and pressure into a liquid, and to store the heat energy generated during this compression process ; During peak electricity demand, the stored thermal energy is used to heat liquid carbon dioxide into a gas, which drives a turbine to generate electricity. This characteristic is closer to the immediate response of lithium batteries, but it allows for longer energy storage, less system degradation, and its cost is less than half that of large lithium batteries.
It is reported that the current mainstream energy storage solution is pumped-storage, but it is highly dependent on geographical conditions. On the other hand, electrochemical energy storage has drawbacks such as a short lifespan, environmental pollution caused by discarded batteries, and high costs. In contrast, carbon dioxide storage systems offer a wide range of power levels, capacities, and geographical adaptability. They provide excellent economic benefits for large-scale, long-duration energy storage, making them suitable for widespread adoption – especially for long-duration storage systems of 10 MW, 100 MW, and 1000 MW scale. According to the energy storage forecast figures presented in the \"2019 White Paper on the Energy Storage Industry,\" it is estimated that by 2050, China’s energy storage capacity will exceed 200 GW, accounting for 10%-15% of the total power generation capacity. There is therefore a huge and urgent demand in this area. New storage technologies such as carbon dioxide storage and compressed air storage offer advantages such as large scale, high efficiency, low cost, and environmental friendliness, and are considered to be storage technologies with significant potential for development on a large scale.
Low-temperature equipment; otherwise Dongfang Electric could definitely handle it
