China has made significant progress in CO2 capture, transport, utilisation and storage systems (CCUS) technology developments in recent years and has acquired the capability to design and demonstrate large-scale CCUS systems.
With the emergence of new technologies, the CCUS technology system itself is gradually getting enriched, covering the complete flow:
CO2 capture technologies are undergoing the transition from the first generation (e.g. pre- combustion physical absorption technology) to the second (Carbon Dioxide Removal technologies CDR such as Bio-Energy with Carbon CaptureandStorage BECCS and Direct Air Capture DAC); meanwhile the third-generation is emerging (e.g. pressurized oxy-fuel combustion POFC and chemical looping combustion CLC).
CO2 transport technologies, moving from road transport to onshore/ offshore pipeline transport, are gradually becoming mature.
CO2 utilization technologies are gradually transitioning from geological utilization for enhanced energy resource recovery (such as CO2-enhanced oil recovery, CO2-EOR), to CO2 chemical and biological utilization, which yield value-added chemical and biological products (mineralization, biotransformation, chemical conversion)
As of November 2022, there are around 100 CCUS demonstration projects with various scales in operation or in planning in China. Here the cases from 2022, some of them previously posted by us:
the first integrated 1 Mtpa CCUS project, "Qilu Petrochemical - Shengli Oilfield CCUS Project," officially came into operation in August
Baogang Steel Group plans to build an integrated 2 Mtpa scale CCUS demonstration project for the steel industry, and the first phase of the 500,000-ton demonstration project has already started construction
- CNOOC, Guangdong Development and Reform Commission, Shell China, and ExxonMobil China signed an MoU to jointly study a lage-scale CCUS hub in Daya Bay
