Advances in research on the policies,technologies,and demonstration projects of geologic CO2 sequestration in China
摘要
Abstract
[Background]Carbon capture,utilization,and storage(CCUS)is considered a key technology to promote large-scale carbon dioxide(CO2)emission reduction.Against the backdrop of achieving its goals of carbon neutrality and peak carbon dioxide emissions,China faces a tremendous challenge of CO2 emission reduction.This situation will provide new driving forces for the development of geologic CO2 sequestration while also imposing higher requirements for technical innovation and industrialization of the technology.[Methods and Advances]This study systematically re-views the development process of policies on CCUS of China over the past two decades,with over 30 policies involved accumulatively.It provides an outline of progress made in CCUS demonstration projects in China,summarizing three major technical directions,i.e.,CO2 sequestration in deep saline aquifers,hydrocarbon reservoirs,and deep coal seams.Among these projects,the 400×104 t/a and 150×104 t/a CCUS pilot demonstration projects lunched by the Shaanxi Coal and Chemical Industry Group Co.,Ltd.and the China Huaneng Group Co.,Ltd.,respectively,represent pioneering efforts in the development of carbon sequestration.The commercial application of CO2-enhanced oil recovery(CO2-EOR)technology has been achieved.For instance,the Jilin oilfield of PetroChina and the Shengli oilfield of SINOPE have achieved cumulative CO2 injection exceeding 350×104 t,increasing oil recovery by 10%to 15%.The CO2-en-hanced gas recovery(CO2-EGR)pilot tests have been conducted in tight-sand gas reservoirs in Yan'an,providing theor-etical support for the synergy between enhanced natural gas recovery and CO2 storage.Furthermore,China's first 10000-ton CO2-enhanced coalbed methane(CO2-ECBM)recovery demonstration project using horizontal wells is to be imple-mented in the Huainan mining area in Anhui Province,aiming to achieve breakthroughs in critical technologies and en-gineering for large-scale CO2-ECBM recovery combined with CO2 storage.Presently,geologic CO2 sequestration tech-nology of China is in a critical stage of transitioning from technical verification to large-scale demonstration.Neverthe-less,this technology still faces a range of challenges in fostering demonstration projects,achieving innovations in basic theories,integrating technical systems,and implementing supporting policies.[Prospects]In the future,it is necessary to intensify interdisciplinary technical innovations,gain deeper insights into the mechanisms and long-term safety of geolo-gic CO2 sequestration,and promote the deep integration and application of artificial intelligence(AI)technologies in geologic CO2 sequestration.It is recommended to promote the collaborative development of the entire industry chain and enhance the support and guidance for medium-and long-term,large-scale CCUS demonstration projects.The purpose is to propel theoretical breakthroughs and technical innovations.Additionally,relevant policies,standards,and incentive mechanisms should be further optimized.All these efforts are expected to comprehensively drive the large-scale devel-opment of geologic CO2 sequestration technology.关键词
