摘要
根据国际通用的温室气体减排计算方法,对海南澄迈日产3万Nm3车用沼气工程所带来的主要温室气体减排量和减排效益进行了估算分析。结果表明:项目每年可减少温室气体排放53 560 t(CO2当量),以上海碳交易市场近年平均交易价格(39.23元/t CO2)计算,可带来210.12万元的经济效益。
In additional to the many of its environmental benefits, a biogas project functions as a two-way cleaning system owing to its environmental attributes. On the one hand, it helps improve the air, soil and water quality by digesting organic waste at the downstream of the chain, which can be used as feedstock in its own system to produce biogas, on the other hand, the use of biogas to generate energy and upgraded gas for vehicle fuel as a renewable alternative to fossil fuels at the upstream of the chain helps reduce greenhouse gas emissions, thus making the biogas industry meaningful in the promotion of energy-saving and emission reduction so as to help ease global warming. The authors analyzed and calculated the greenhouse gas emission reductions and the mitigation benefits at a 30 000 Nm3/d BioCNG project in Hainan using internationally accepted methods. The results show that the project can reduce greenhouse gas emission by 53 560 t （CO2 e） per year. This means that the project may create a potential income of 2.101 2 million yuan if it trades at Shanghai carbon trading market at the average price of recent years （1 t CO2=39.23 yuan）.
