摘　　要：可再生能源的发展是减少温室气体排放的重要措施之一。以青岛市某静脉产业园为研究对象,基于国家核证自愿减排量(CCER)方法学CM-072-V01,对5种沼气利用方式即火炬燃烧、入炉焚烧发电、内燃机发电、锅炉供热、提纯制天然气的碳排放进行评估和比较,以确定最低碳的利用方式。结果表明,5种沼气利用方式的碳减排量由高到低依次为:内燃机发电(9505.18 tCO 2e)、锅炉供热(9048.36 tCO 2e)、入炉焚烧发电(5963.83 tCO 2e)、提纯制天然气(4658.73 tCO 2e)、火炬燃烧(-7695.04 tCO 2e)。选取沼气作为替代能源利用时,应考虑项目所在地、替代能源类型以及设备能耗等因素。在华北地区,采用内燃机发电是最为低碳的沼气利用方式,具有较高的碳减排效益。Renewable energy development is one of the essential measures to reduce greenhouse gas emissions.This study was conducted to assess and compare the carbon emissions of five biogas utilization methods,and taking a vein industrial park in Qingdao as an example.The Chinese Certified Emission Reduction methodology CM-072-V01 was used to compare flare combustion,incineration for power generation,internal combustion engine for power generation,boiler for heating,and purification for natural gas to determine the most low-carbon utilization method.The results showed that the carbon emission reductions of the five biogas utilization methods were in descending order:internal combustion engine for power generation(9505.18 tCO 2e),boiler for heating(9048.36 tCO 2e),incineration for power generation(5963.83 tCO 2e),purification for natural gas(4658.73 tCO 2e),and flare combustion(-7695.04 tCO 2e).When selecting biogas as an alternative energy source,factors such as project location,the type of alternative energy,and equipment energy consumption should be considered.In North China,using an internal combustion engine for power generation is the most low-carbon way to biogas utilization method,which has higher carbon emission reduction benefits.
