Photovoltaic Power Generation is one of the most promising “carbon emission reduction” proposals in the world. However, that if photovoltaic array deployment can change the ecological system (also called “host ecological system”) is not fully taken into consideration during the operation of photovoltaic power station. In order to evaluate the influence of photovoltaic array on the emission of greenhouse gas, through locating and monitoring the photovoltaic array and grassland vegetation, microclimate and greenhouse gas (CO2, CH4 and N2O) around it, and considering the designed life circle and total power production, the team led by Professor Xing Fu created an evaluation model of greenhouse gas footprint during the operation of photovoltaic power station in the grassland ecological system. It is concluded that 33.14 % on average of greenhouse gas footprint of photovoltaic power generation in the past is underestimated. Ignoring the effects of photovoltaic array deployment on greenhouse gas emissions may lead to overestimation of the contribution of photovoltaic power generation to greenhouse gas reduction.
With the title of “Ignoring the Effects of Photovoltaic Array Deployment on Greenhouse Gas Emissions May Lead to Overestimation of the Contribution of Photovoltaic Power Generation to Greenhouse Gas Reduction”, this result was published on Environmental Science & Technology, an international academic journal. Doctor Zhang Bin is the lead author, Professor Xing Fu is the corresponding author, and NENU is the first communication unit.
