Does China have a CO2 storage capacity?

The theoretical CO 2 storage capacity in China's main sedimetary basins was evaluated, it is found that China has large prospects of CO 2 storage capacity, which is estimated to be about 1841 Gt, more than 190 times of China's total CO 2 emission in 2015.

How to evaluate CO2 storage potential in China?

In this paper, a comprehensive evaluation method of CO 2 storage potential was established, which include storage site screening, storage mechanism analysis, and storage capacity evaluations. With the evaluation method, CO 2 storage capacity was evaluated in China, and CCUS prospect was investigated, and some key findings are obtained.

What is CO2 energy storage (CCES)?

The technology of compressed carbon dioxide (CO 2) energy storage (CCES) is further proposed according to CAES as well as CO 2 power cycle. Because of the distinct thermophysical characteristics of CO 2, CCES exhibits superior performance. Firstly, CO 2 has a high critical temperature (304.5 K).

How much geological storage capacity does China have?

There is a total estimated theoretical CO 2 geological storage capacity of 3088 gigat ons in China’s onshore and offshore basins, including a storage capacity of 3066 gigatons for deep saline formations accounting for 99% of total geological storage resource.

How to evaluate CO2 storage capacity?

Nowadays, many institutions & organizations provide simplistic methods to evaluate CO 2 storage capacity in different formations , , , . These include the Department of Energy (DOE) method, the Carbon Sequestration Leadership Forum (CSLF) method, United States Geological Survey (USGS) method, and Zhou's method.

How does Zhou calculate CO2 storage capacity?

Zhou's method is based on reservoir compressibility properties and solubility of brine to calculate CO 2 storage capacity in closed formations, but the greater the formation pressure the higher the risk of CO 2 leakages.
