Abstract
As an emerging technology with the potential to enable large-scale utilization of fossil fuels in a low-carbon manner, carbon capture, utilization and storage (CCUS) is widely considered to be a strategic technology option to help reduce CO2 emissions and ensure energy security in China. In principle, CCUS can be divided into three categories, namely chemical utilization, biological utilization and geological utilization. Of the three categories, carbon geological utilization and storage (CGUS) technology has obtained the most attention lately due to its ability to utilize underground resources and conditions, to generate further economic benefits, a feature that distinguishes it from other CO2 reduction technologies. The CGUS technology related in this paper has various types, each with its own potential, difficulties and characteristics. This paper summarizes China’s research findings on the various types of CGUS technology, analyzes their research status, development potential, early opportunities and long-term contributions and recommends major geological utilization methods to policy makers and investors based on China’s natural resources and industrial characteristics. Besides, this paper analyzes the status, mechanisms and limitations of China’s relations with other countries in this field, as a means to promote research cooperation on an international level.
