DAC as a solution to negatively increase carbon dioxide in the atmosphere. People are paying more and more attention to this scheme. Despite technological breakthroughs in the past decade, the current principles, limitations and effects of DAC are poorly understood. This paper through collation, literature review and other methods to describe the realization principle of DAC and the expected effect of DAC. The paper finds that there is a problem with DACs, which is the usage of CaCO3 to make use of electricity when it needs to heat and blow air to contactors, because that way would generate abundant CO2 and the DAC would be advanced in its efficiency as long as the problem is solved. Besides, compared with other methods of absorbing carbon dioxide, the cost of DAC is very low, and it can absorb the carbon dioxide released from different places, such as car driving, which also accounts for a large part of the carbon dioxide emissions. Thus, the use of DAC currently is of great significance.
