中国水层CO2地质封存技术攻关方向
Research direction of CO2 geological storage technology in aquifers in China
摘要
Abstract
Under the national strategic goal of"carbon peaking and carbon neutrality",a major revolution in large-scale carbon emission reduction is in urgent need to extend the life cycle of the fossil energy industry.And a consensus has been reached globally that carbon capture and storage(CCS)is a backing technology for large-scale carbon emission reduction.In this paper,the development trend of CCS all over the world are reviewed systematically.Then,the challenges and difficulties in the development of aquifer CCS in China are analyzed from the aspects of geological characteristics and engineering technological status of domestic CCS.Finally,the technological research direction of aquifer CCS in China are pointed out.And the following research results are obtained.First,aquifer CCS started early China,and it is now in the stage of world-class scale aquifer CCS pilot test,with the technological level equivalent to the international level,so CCS is expected to become the main means of large-scale carbon emission reduction in China in the future.Second,in view that most aquifers in China have the innate conditions such as continental deposition,developed fractures and strong heterogeneity,the future construction of large-scale aquifer CCS in China cannot avoid the technical challenges from the key technologies in terms of large storage scale,high storage cost and long-term storage safety.Third,to promote and form a new CCS negative carbon industry,the future aquifer CCS in China needs to realize breakthroughs in five key technologies,including CCS geological body assessment,high-speed CO2 injection,low-concentration CO2 storage,cost reduction and geological monitoring.In conclusion,this research further strengthens the confidence to develop aquifer CCS technologies in China,and the proposed five key technologies point out the research direction of the rapid formation of a national strategic scientific and technological force in the field of negative carbon,while providing forward-looking technical support for the next development of large-scale underground hydrogen storage,helium storage,compressed air energy storage and other strategic emerging industries.关键词
