Carbon capture,utilization,and storage(CCUS)refers to a set of technologies that capture carbon dioxide(CO2)from sources like energy production,industrial processes,biomass combustion,and directly from the atmosphere.This CO2 is then transported to suitable sites where it is either utilized or stored,effectively reducing emissions.CCUS plays a critical role in helping countries achieve their climate goals by enabling significant reductions in CO2 emissions across various sectors.It is an essential technological support for global climate action.After China's carbon neutrality goal was proposed,the country has established a policy framework relating to the targets.China is actively promoting deep technological innovation and systemic transformation across various industries to meet these climate objectives.CCUS is a major solution for enabling large-scale,low-carbon use of fossil fuels,providing a feasible pathway for deep decarbonization in hard-to-abate industries such as steel and cement.Additionally,it serves as a crucial technology for offsetting residual greenhouse gas emissions in the future,supporting long-term climate goals.To achieve the climate goals of both China and the United States,both countries ultimately need to achieve annual reductions of billions of tons of carbon dioxide through CCUS technology.The United States is currently leading global practice in CCUS development,with relative advantages in policy development,infrastructure,and large-scale project operations.To support its net-zero emissions goals,the U.S.has accelerated the large-scale deployment of CCUS projects through effective fiscal and tax incentives.These experiences provide valuable insights for other countries looking to advance CCUS initiatives.By comparing the potential demand,policies,regulations,and R&D demonstrations in the field of CCUS technology between China and the United States,this article provides references for the development of CCUS technology and its supporting policy environment in China,and proposes potential directions for cooperation between China and the United States in the field of CCUS technology.
