直接空气二氧化碳捕集技术工业化进展
Industrial progress in direct air CO2 capture technology
摘要
Abstract
Direct air capture(DAC)is a technology that can capture carbon dioxide from the atmosphere.This article introduces the development history,technical advantages and disadvantages,and development prospects of DAC technology.According to predictions,by 2050,the global annual demand for capturing carbon dioxide from the atmosphere will exceed 980 million tons.It reviewed the current status of policy support and funding for DAC technology.Countries and regions such as the United States,Canada,the European Union,and the United Kingdom have become pioneers in the research,development,demonstration,and deployment of DAC technology.The mainstream DAC technology routes and their progress in the industrialization process were analyzed.The current largest DAC plant had a capture capacity of 4000t/a,and there were plans to build million-ton commercial projects.It pointed out the research directions that DAC technology needs to focus on,suggesting that future efforts should focus on large-scale deployment of the technology,establishing carbon market mechanisms,and strengthening international cooperation.Further research and development of DAC equipment and systems are needed to reduce costs,improve efficiency,and develop mechanisms such as carbon pricing,carbon trading,and carbon offsetting to provide economic incentives for DAC projects,promote investment and market participation,and strengthen international cooperation,thus accelerating the rapid development of this technology.关键词
