摘　　要：为了评估国内天然气余压发电的碳资产开发潜力,使天然气余压发电方法学符合生态环境部备案要求,通过实际调研和行业分析,根据CCER方法学编制大纲的要求,参考CDM等碳信用体系的方法,对天然气余压发电CCER方法学编制的关键点进行分析研究,提出天然气余压发电方法学编制关键要素,形成额外性、监测管理的设计。研究结果表明:①通过分析油气田、长输管线和门站等各环节蕴含的天然气余压发电潜力和碳资产开发潜力,给出了天然气余压发电潜力数据(145.73×10^(8) kWh/a)以及相应的碳资产开发潜力数据(811.44×10^(4) tCO_(2)e/a);②在方法学额外性设计方面,首先明确了用于比较额外性的基准线情景,在结合发电潜力分析结论和实施现状对比的基础上,提出直接采用免予论证的方式;③在方法学监测设计方面,遵循可信、准确和保守性原则,描述了监测所需的项目边界,并根据减排量计算方法,确定设计阶段和实施阶段应当分别纳入监测的参数、数据,以及保证监测质量的方法。Some investigation and professional discussion have been carried out in an effort to estimate the development potential of carbon asset from natural-gas residual pressure power generation and make this generation's methodology meet-ing filing requirements of the Ministry of Ecology and Environment of the People's Republic of China.Furthermore,the key to work out this methodology was analyzed according to methodological compilation needs through reference on a car-bon-credit system of CDM.In addition,the decisive elements were proposed for the compilation of such generation method-ology,and an additional and monitoring management was designed.Results show that(i)via the evaluation on the potential of both residual pressure power generation and carbon-asset development in different links such as oil and gasfields,long-distance pipelines,and gate stations,these two sorts of potential achieved are 145.73×10^(8) kWh/a and 811.44×10^(4) tCO_(2)e/a,respectively;(ii)as for the additional methodological design,baseline scenarios are made certain to contrast the additionali-ty.And it is proposed to directly adopt exemption from demonstration based on the potential analysis on power generation and practical work;and(iii)as for the monitoring design of methodology,the principles of credibility,accuracy and conser-vation should be followed,and monitoring projects'boundaries are described.Parameters and data which should be relative-ly surveyed in not only design but implementation stages,and the method to ensure surveying quality is defined by using emission-reduction calculations.
