Abstract
- In this study, CO 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 storage capacity evaluations in China, initiated by the Chinese Ministry of Land and Resources. This level of CO 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 t CO in coalbed s buried at a depth range of 1,000-2,000 m and 4.26 × 10 m additional coalbed methane can be recovered by CO injection. These results appear to show great potential and an attractive economic perspective of CO storage in unmineable coalbeds in China. Another part of this study is to classify the potential coalbed basins based on CO storage capacity and storage capacity per unit area. The study results reveal the distribution of the most potential basins for large-scale CO storage and the best economic basins for early CO storage in the future. [ABSTRACT FROM AUTHOR]
