Abstract: At present, the fossil fuel still plays a dominant role to satisfy the energy needs domestically, especially in the form of
coal-fired power plant. Thus, it is most likely for CO2 capture technology to be an important choice to achieve carbon neutrality.
By systematically combing the principles and characteristics of mainstream CO2 capture technology, this paper concluded that
oxy-combustion, especially the chemical looping combustion and the CaO-based looping capture technology is of good coupling
with the process of coal-fired power plants and of lower costs, which is suitable for the technological transformation of the coalfired
power plant stock market.
