基于全生命周期法的储能技术减排降碳效益评估

Evaluation of Carbon Reduction Benefit of Energy Storage Technology Based on the Whole Life Cycle Method

基于“双碳”战略下的电网技术创新趋势,新型电力系统建设向能源电力低碳方向转型发展。储能技术作为“源网荷储”创新技术体系中的重要创新技术,衡量其减排降碳效益具有重要意义。构建了基于全生命周期法的储能技术碳足迹核算模型,明晰了储能技术各生命周期阶段的碳足迹,构建了3个减排降碳效益指标,用以评估储能技术的减排降碳效益。通过灵敏度分析了影响储能技术减排降碳效益的主要因素,并提出了相应的管理模式,以便进一步提高储能技术的减排降碳效益。

Based on the trend of grid technology innovation under the"dual carbon"strategy,the construction of new power systems is transforming and developing towards low-carbon energy and electricity.Energy stor⁃age technology,as an important innovative technology in the"source network load storage"innovation sys⁃tem,is of great significance in measuring its emission reduction and carbon reduction benefits.A carbon foot⁃print accounting model for energy storage technology based on the full life cycle method was constructed to clarify the carbon footprint of energy storage technology at each lifecycle stage,and three emission reduction and carbon reduction benefit indicators were constructed to evaluate the emission reduction and carbon reduc⁃tion benefits of energy storage technology.By analyzing the main factors that affect the emission reduction and carbon reduction benefits of energy storage technology through sensitivity analysis,corresponding manage⁃ment models are proposed to further improve the emission reduction and carbon reduction benefits of energy storage technology.
