低碳背景下分布式能源系统

Distributed Energy System under Low-Carbon Background

目前,我国农村居民每年冬季约使用2亿吨标准煤进行取暖,农村供热造成的碳排放问题不容忽视。采用分布式能源系统能够解决北方农村等不具备集中供暖地区的碳排放问题。分布式能源系统综合能源利用率高达85%,极大地降低了能源损耗,减少温室气体及碳排放,对实现碳达峰、碳中和具有积极的意义。文章结合燃气内燃机对分布式能源系统如何实现冷热电三位一体的能源使用方式进行简述,论述了分布式能源系统在能源节约、环保效益和经济运行方面的优势,是解决和改善现有能源结构及能源供应的有效途径,是推动“双碳”目标实现的重要手段。

At present,rural residents in China use about 200 million tons of standard coal for heating every winter and the carbon emissions thus caused cannot be ignored.The use of distributed energy system can solve the problem of carbon emission from energy use in areas without central heating such as rural areas in northern China.The comprehensive energy utilization rate of distributed energy system is as high as 85%,which greatly reduces energy loss,greenhouse gases and carbon emissions,and has a positive significance for achieving carbon peaking and carbon neutrality.This paper briefly describes how to achieve the trinity way of using cold,hot and electricity in distributed energy system combined with gas internal combustion engine.It also discusses that the distributed energy system,due to its energy-saving,environmental and economic advantages,is an effective way to solve and improve the existing energy structure and energy supply and is key to promote the realization of the"two-carbon"goal.
