数字化能源管理系统促进工业界节能减碳的分析与建议

Analysis and recommendations for energy conservation and carbon emission reduction in industry boosted by digital energy management systems

工业生产是碳排放的主要来源。减少能源浪费、达成生产节能对实现我国“双碳”目标至关重要。随着数字化技术进步,数字化能源管理系统可通过将不可见的能源可视化,促进企业节能。文章分析了英国、美国、德国、日本和瑞典应用能源管理系统的现状,总结了其特点与应用条件,与我国在此方面的发展进行了对比,并探讨了我国在部署能源管理系统过程中所面临的挑战。文章还提出从“工厂、产线和设备”到“产品”角度分析能耗,构建“基于生产步骤的单位产品能耗标签”的方法论框架。探讨了政府、企业等利益相关者在该方法论中的角色,并提出了政府支持发展数字化能源管理系统的对策,包括推动系统建设、支持合作、确定能耗基准和引导企业对标行业最优实践。

Energy consumption during production processes in the industry is a main source of carbon dioxide emissions.Therefore,for China’s dual-carbon goals,industrial enterprises need to focus on reducing energy waste to achieve energy-efficient production,thereby effectively reducing carbon emissions in industrial production.In recent years,with the continuous development and popularization of digital technology,digital energy management systems have played a crucial role in energy saving by visualizing invisible energy in the industry.In this context,this study first analyses the current status of digital energy management system applications in the UK,the US,Germany,and Sweden,summarizes their characteristics and conditions,and compares the differences between China’s energy management system development and other countries’.Furthermore,this study explores the challenges faced by the government,technology,and enterprises in promoting the deployment of energy management systems in Chinese industrial enterprises.Next,the study proposes to analyse energy consumption from the perspective of product rather than factory,production lines,or machines.The concept of“unit product energy consumption label based on production steps”is defined,and a methodological framework for digital energy consumption data analysis based on this label is constructed.This study further discusses the roles of the major stakeholders,including governments,enterprises,digital energy management system technology providers,certification bodies,etc.,in achieving standardization and unified analysis of energy consumption labels and puts forward suggestions for the government to develop digital energy management systems in the industry to reduce carbon emissions.The suggestions include:continuing to promote the construction of energy management systems in enterprises;continuously supporting the cooperative development among various stakeholders;gradually determining energy consumption benchmarks by product and production steps;and actively leading enterprises to benchmark industry best practices.
