新建天然气热电联产项目碳减排量化方法的应用
|
摘要
热电联产项目节能、环境效益俱佳,如若将其申请为中国核证减排量(CCER)项目,不仅可通过碳交易产生经济效益,还可以推动热电企业的节能减排工作。然而针对天然气热电联产项目的碳减排量化之前一直未有合适的方法学以供参考和应用。发改委公布的自愿减排方法学CM-038-V01"新建天然气热电联产电厂"为天然气热电联产项目提供了碳减排量化方法。对方法学的适用条件、项目边界、基准线情景识别、基准线温室气体排放量、项目温室气体排放量、泄漏量及温室气体减排量等方面进行分析,并通过具体案例验证其实用性和可操作性。华东地区某热电联产项目建设两台2×400MW级燃气-蒸汽联合循环热电联产机组,项目投产后预计可实现年发电量4480GW·h,年供热量5655000GJ,年消耗天然气(标准状态)87400×10~4m~3,通过应用方法学计算方法得到该项目预计年均可减少温室气体排放506122t二氧化碳当量。研究内容实现了对新建天然气热电联产项目温室气体的"报告、测量与核查"(MRV)体系的完善,可为我国开展相关项目提供碳减排量计算、数据监测等技术借鉴。
Cogeneration project has good energy saving and environmental benefits. If it is applied to be a Chinese Certified Emission Reduction(CCER) project,economic benefits can be obtained through carbon trading and the energy saving and emission reduction of thermal power enterprises can be promoted.However,there had been no suitable quantification methodology for carbon emission reduction in natural gas-fired co-generation projects for reference and application.CM-038-V01 New Natural Gas-fired Cogeneration Plant,the voluntary emission reduction methodology released by the National Development and Reform Commission,provides a quantification method for carbon emission reduction in natural gas-fired cogeneration projects.This paper analyzes the applicable conditions of the methodology,the project boundaries,the baseline scenario identification,the baseline greenhouse gas emissions,and the project greenhouse gas emissions,leakage and greenhouse gas emission reductions,and verifies its practicality and operability through specific cases.Two sets of2×400MW gas-steam combined cycle cogeneration units are planned for a cogeneration project in East China.After the project is put into operation,it is expected to achieve an annual power generation of 4480GW·h,an annual heat supply of 5655000 GJ and an annual natural gas consumption(standard state) of 87400 ×10~4m~3.It is obtained through methodology calculation method that the project is expected to reduce greenhouse gas emissions by 506122 tons of carbon dioxide equivalent annually.The research has improved the Measurement,Reporting and Verification(MRV) system for greenhouse gases of new natural gas-fired cogeneration project,providing reference for the carbon emission reduction calculation and data monitoring of related projects in China.
