摘要:

六氟化硫(SF6)的减排是电力行业服务“碳达峰、碳中和”的攻坚环节,文章总结了电力行业温室气体SF6排放现状和主要排放源,从开源、节流、升级和降解角度出发,总结了四种SF6减排手段,即源头替代、回收净化、设备升级以及无害化处理等,综述了各种技术存在的问题及对策。通过SF6减排技术优先选择性分析,提出了SF6气体减排分“两步走”战略,为构建绿色低碳新型电力系统以及实现“净零”目标提供参考。建议加强对非CO2温室气体SF6的政策约束力度、进一步制定针对电力行业的SF6气体减排目标、加快SF6气体减排技术应用进程、建立完善的SF6全生命周期管理方法,促使我国SF6气体管控再上新台阶。

Abstract:

The reduction of sulfur hexafluoride (SF6) emissions is a key link in the power industry's efforts to serve the “carbon peak and carbon neutrality”. This article summarizes the current status and main sources of greenhouse gas SF6 emissions in the power industry, and from the perspectives of open source, cost reduction, upgrades, and degradation, summarizes four SF6 emission reduction measures: source replacement, recycling purification, equipment upgrading, and harmless treatment. It also reviewes the problems and countermeasures of various technologies. Through a selective analysis of SF6 emission reduction technologies, this article proposes a two-step strategy for reducing SF6 emissions, providing reference for building a green, low-carbon new power system and achieving the “net zero” goal. It suggestes strengthening policy constraints on non-CO2 greenhouse gases such as SF6, further formulating SF6 emission reduction targets for the power industry, accelerating the application process of SF6 emission reduction technologies, establishing a sound SF6 life cycle management approach, and promoting China's SF6 gas control to a new level.

Key words: sulfur hexafluoride, greenhouse gas, emission reduction, substitute, recycling purification
