The Energy Consumption and Environmental Impacts of Biomass Power Generation System in China

Combined with practical operation of a biomass direct-fired power pant in South China, the whole life cycle of the process, including biomass growing, transportation, pretreatment, combustion power generation and power plant manufacturing are analyzed by means of LCA. The energy consumption and the impact on environment in each stage are also collected and calculated. The results show that 2182.32 MJ fossil energy is consumed to generate 104 kWh power. The total loading of the impact on environment is 13.45 PET2000 and the mainly impact on environment is soot and ashes. Compared with coal-fired power, biomass direct-fired power plant can reduce 5282.87 kg CO2 emissions during the process of generating 104 kWh power, which plays a positive part in mitigating greenhouse gases.
