China's action and strategy for CCS lChinese government adopted several incentive policies to promote the demonstration of CCS projects. CCS incentive policies from Chinese Government since 2006 (Li, Ma and Yang, 2015,WRI) lThe most important government plans to realize CCS projects are: l Energy technology innovation action plan by NDRC and NEA in April 2016 l The 13th Five-Year Plan for National Scientific and Technological Innovation by MOST in August 2016 Year Agency Document The outline of the national program for long and medium 2006 The State Council of PRC term scientific and technological development (2006-2020) The National Development and Reform China’s National Climate Change Program Commission (NDRC) 2007 Ministry of Science and Technology China's national climate change technology initiative (MOST), NDRC China's Policies and Actions for Addressing Climate 2008 NDRC Change The 12th Five-Year Plan for the National Science and MOST Technology Development 2011 The 12th Five-Year Work Plan for controlling greenhouse The State Council of PRC gas emissions program MOST, Ministry of Foreign Affairs, The 12th Five-Year Plan for National climate change NDRC etc. technology development The 12th Five-Year special plan for the development of MOST clean coal technology Ministry of Industry and Information Industrial areas of the Program of Action to address Technology (MIIT), NDRC et al. climate change (2012-2020) 2012 Long term planning for the construction of national major The State Council of PRC scientific and technological infrastructure (2012-2030) Notice of NDRC on promoting carbon capture, utilization NDRC and storage pilot and demonstration Notice on strengthening the environmental protection Ministry of Environmental Protection work of carbon capture, utilization and storage (MEP) demonstration projects Year Agency Document NDRC National Climate Change Plan (2014-2020) NDRC Provisional Administrative Measures on Carbon emissions trading 2014-2015 Special Action Program for energy saving and emission MOST,MIIT reduction technology 2014 NDRC, MEP, National Energy Coal power energy saving and emission reduction promotion and Administration (NEA) improvement action plan (2014-2020) NDRC Low carbon technology catalog of national key promotion Chinese Government China-US Joint Announcement on Climate Change Interim Measures for the administration of subsidies for energy Ministry of Finance conservation and emission reduction 2015 The 18th Central Committee of The 13th Five-Year Plan of the Central Committee the Communist Party of China recommendations Chinese Government China-U.S. Joint Presidential Statement on Climate Change NDRC, NEA Energy technology innovation action plan Strategic emerging industries key products and services guidance NDRC 2016 directory The 13th Five-Year Plan for National Scientific and Technological MOST Innovation MOST, Ministry of Land and The 13th Five-Year Plan to deal with climate change science and 2017 Resources, China technology innovation special planning Meteorological Administration The scientific and technological innovation 2030 project - Clean and Highly Efficient Utilization of Coal Major Program Four fields of research: l Coal green development (40% of budget); l Highly efficient coal power generation (30% of budget); l Clean coal conversion (20% of budget); l Carbon capture, utilization and storage (10% of budget) http://www.most.gov.cn/mostinfo/xinxifenlei/ gjkjgh/201608/t20160810_127174.htm Roadmap for Carbon Capture and Storage (CCS) demonstration and deployment in the PRC by National Development Reform Commission (NDRC) of PRC and the Asian Development Bank (ADB) 2.

The first phase (2008 to present), the injected CO2 is from the nearby well Changshen4 which produces natural CO2 gas with a high purity up to 97 mol% (Zhang et al.,2015). The second phase is an enlarged test which will be conducted in the H-79 block (2011 to present). The Changling gas field close to the H-79 block has a CO2 concentration of 21–23 mol%. A natural gas treatment plant is under plan to separate the CO2 from The produced gas stream with an annual capacity of about 600,000 tons (Zhang et al.,2015).

Northwest University and Shaanxi Yanchang Petroleum Group started to implement Jingbian CCS Project sponsored by the National High Technology Research and Development Program (863 Project). CO2 injection start date September 4, 2012. CO2 capture start date November 29, 2012, at Yulin Coal Chemical Company. GCCSI started to sponsor July 2, 2013. Becoming China’s Sep.5, 2014. The National Development and Reform Demonstration Project Commission (NDRC) chose Jingbian CCS Project as a key low carbon demonstration project of China. 863 project of the first phase June 12, 2015 finished Recognized by CSLF June 15,2015 Amount of injected CO2 about 60,000 tons by the end of June, 2016. China-U.S. Joint Presidential Planning 1 M tons CCUS project. Statement on Climate Change NDRC and ADB prepared TA project. CO2 Capture and Transportation l Yulin Coal Chemical Company of Shaanxi Yanchang Petroleum Group will produce acetic acid 1 million tons/year. In its first phase, it has been producing acetic acid about 200, 000 tons/year with CO2 emission about 52,000 tons/year since March, 2011.
