Abstract:

Energy storage is an important supporting technology for building the new power system and achieving dual carbon goals. Green energy storage embodies the principles of environmental protection, resource efficiency, and energy optimization throughout the product lifecycle, making it a key trend in energy storage technology amidst efforts to peak carbon emissions and achieve carbon neutrality. This paper analyzes relevant regulations and standards that promote the development of green industries and proposes the construction of a green energy storage standard evaluation system through multi-dimensional analysis, such as energy storage technology routes, industrial chain compositions, and life cycle assessments. In addition to focusing on green products, green energy storage standards should encompass green design, manufacturing, operation, and recycling to address the whole lifecycle of energy storage systems. According to the standard of green energy storage products, the selection of evaluation indicators and the determination of benchmark values are examined. It is proposes primary indicators such as resource attributes, energy attributes, environmental attributes, and quality attributes, with secondary indicators including recycling rates, comprehensive energy consumption, and carbon footprint. Quality attributes should serve as the basis for the evaluation of other attributes. The paper also analyzes the formulation of green energy storage product standards, using lithium-ion battery modules as a case study, and summarizes the development of other green energy storage standards. The goal is to promote the development of green energy storage technology, provide a reference for creating and refining green energy storage standards, and support the sustainable development of the new energy storage industry.
