Economic Impact of the Comprehensive Environment of Different Clean Coal Technology Choice

We analyze the clean coal technology choice and the corresponding cost,social and economic effect on Chinese possible carbon emissions peak from both the micro and the macroaspects.From the microaspect,four kinds of most promising and competitive clean coal power generation technology are chosen:the ultra(ultra)supercritical unit(SC/USC),circulating fluidized bed combustion(CFBC),integrated gasification combined cycle(IGCC).Then we design different scenarios for technology choice,which shows the possible carbon peak emission and peak year in China.From the macroaspect,the technology choices are integrated in PIC model for the simulation of the effects of economic growth,employment and industry,which can also evaluate the cost benefit of different clean coal technology choices.Results show that(1)there is no carbon emission peak appears before 2050 in the basic technology scenarios,while in the strong low carbon technology scenarios,the other three techniques scenarios lead to carbon emissions peak in the 2039 and 2040except CFBC technology scenario;(2)among the four clean coal technologies,IGCC is the most promising clean coal technology because of its emission reduction potential and low cost.China can rely on the optimization choices of clean coal technology to realize carbon emission peak before 2050.
