Quantitative Method and Application of Carbon Emission Reduction Benefits in Energy Storage

With the intensification of global climate change, carbon emission reduction has become a global consensus. Energy storage technology, as a critical enabler for large-scale renewable energy deployment and energy efficiency improvement, demonstrates significant carbon reduction benefits. However, current quantitative methods for evaluating the carbon reduction benefits of energy storage remain underdeveloped, lacking unified standards and frameworks, which hinders accurate assessment of its actual contributions. Addressing the gap in quantitative methodologies for energy storage carbon reduction, this paper proposes a carbon reduction benefit quantification approach based on the baseline methodology and project methodology, drawing on the Clean Development Mechanism (CDM) and China Certified Emission Reduction (CCER) methodologies. By establishing emission reduction scenarios and baseline scenarios for energy storage projects, this method quantifies carbon reduction benefits in terms of reducing fossil fuel consumption and enhancing renewable energy utilization. To validate the method's effectiveness, a case study of a practical project in China was conducted. Results indicate that the proposed carbon reduction calculation method exhibits high feasibility and reliability. This research provides a scientific basis for assessing the carbon reduction benefits of energy storage technologies, with significant implications for scaling up energy storage applications, accelerating energy structure transformation, and achieving carbon neutrality goals.
