A preliminary evaluation of carbon dioxide storage capacity in unmineable coalbeds in China
Abstract In this study, $ CO_{2} $ storage capacity in unmineable coalbeds in China at depths of 1,000–2,000 m has been evaluated using the methodology recommended by CSLF. This evaluation is one part of the countrywide $ CO_{2} $ storage capacity evaluations in China, initiated by the Chinese Ministry of Land and Resources. This level of $ CO_{2} $ storage capacity evaluation gives a rough scale of assessment with the least site-specific detail. The results show that there is a storage capacity of 98.81 × $ 10^{8} $ t $ CO_{2} $ in coalbeds buried at a depth range of 1,000–2,000 m and 4.26 × $ 10^{12} $ $ m^{3} $ additional coalbed methane can be recovered by $ CO_{2} $ injection. These results appear to show great potential and an attractive economic perspective of $ CO_{2} $ storage in unmineable coalbeds in China. Another part of this study is to classify the potential coalbed basins based on $ CO_{2} $ storage capacity and storage capacity per unit area. The study results reveal the distribution of the most potential basins for large-scale $ CO_{2} $ storage and the best economic basins for early $ CO_{2} $ storage in the future.
