【摘要】：随着我国海上风电的快速发展,对其资源环境成本进行系统核算对于全面评价海上风电的节能减排潜力具有重要意义.本研究采用混合生命周期评价方法,对我国第一个海上风电场—上海东海大桥海上风电场(二期)的能耗和温室气体排放进行核算,并将核算结果与典型陆上风电场和其它类型的可再生能源进行比较.结果表明:该海上风电项目全生命周期发电能耗为0.51 MJ·k Wh~(-1),相应的温室气体排放量为26.47g·k Wh~(-1)(以CO_2当量计);在设备制造与运输、建设施工、运行维护、回收处置4个阶段中,设备生产与运输阶段在能耗和温室气体排放的占比最大,分别贡献了能耗的91.23%和温室气体排放量的60.48%;横向比较发现,海上风电场单位发电量的能耗和温室气体排放均高于陆上风电项目,但与光伏、生物质、地热等可再生能源发电项目相比,海上风电项目全生命周期能耗和温室气体排放依然具有一定优势.
[Abstract]:With the rapid development of offshore wind power in China, it is of great significance to evaluate the energy saving and emission reduction potential of offshore wind power through systematic accounting of its resources and environmental costs. In this study, the energy consumption and greenhouse gas emissions of the first offshore wind farm, Shanghai Donghai Bridge Offshore Wind Farm (Phase II), were calculated by using the mixed life cycle evaluation method. The results are compared with typical onshore wind farms and other types of renewable energy. The results show that the whole life cycle energy consumption of the offshore wind power project is 0.51 MJ k Whi ~ (-1), and the corresponding greenhouse gas emission is 26.47 g / h ~ (-1) (calculated as CO_2 equivalent); in the four stages of equipment manufacture and transportation, construction, operation and maintenance, recovery and disposal, Equipment production and transportation accounted for 91.23% of energy consumption and 60.48% of greenhouse gas emissions respectively in terms of energy consumption and greenhouse gas emissions. The energy consumption and greenhouse gas emissions per unit generation of offshore wind farms are higher than those of onshore wind power projects, but compared with renewable energy generation projects such as photovoltaic, biomass, geothermal, etc. Offshore wind power project life-cycle energy consumption and greenhouse gas emissions still have some advantages.
