Recently, with the development of human industrial activity, atmospheric CO_2 level increases year by year. Therefore, it's necessary to reduce CO_2 emission to deal with global warming. As a key source of CO_2 emission, it's easier to capture CO_2 by CCS technology. When the regulatory measures of mandatory reduction and economic incentives appear, CCS Ready plants can be transformed into CCS power plants more easily, reducing the cost of implementing CCS technology. Power plants were taken for example to describe the significance and research status of CCS Ready for power plants, as well as the challenges and prospects of developing CCS Ready plants in China.
