Co-Benefits of Integrating PM10 and CO2 Reduction in an Electricity Industry in Tianjin, China

Based on the actual PM10 and CO2 emissions in 2010, and the projected situation in 2015, this study assesses the co-benefits of the Local Air Particulate Matter (LAP) reduction plan and Greenhouse Gas (GHG) control plan in a coal-fired power industry in Tianjin, China. This co-benefit analysis used the Ambient Least Cost Model (ALC) to estimate PM10 and CO2 emission reduction and cost, then developed a PM10 and CO2 control technologies inventory. The results show that a rebuilt bag-house precipitator in 300 MW units is most cost-effective method of reducing PM10 emissions in a thermal power plant. In contrast, CCS-MEA is the most effective option for reducing CO2 emissions in the existing plant. The results of the cost-benefit analysis indicated that using a Nuclear Power plant is the most cost effective way to reduce PM10 and CO2 emissions at the same time, but IGCC is a safer choice for Tianjin. The integrated environmental strategy (IES) scenario presented in this work makes it possible to reduce CO2 emissions by 28,095,386 t and PM10 emissions by 35,930.73 t, at a cost of 9.69 billion Yuan from 2010 to 2015, which is better than both suggested targets (ST) for PM10 and CO2 during the Twelfth Five-Year Plan.
