Classification and analysis of energy storage economy research The techno-economic analysis of ESS has garnered substantial discourse.
The economic end of life is when the net profit of storage becomes negative. The economic end of life can be earlier than the physical end of life. The economic end of life decreases as the fixed O&M cost increases. The useful life of electrochemical energy storage (EES) is a critical factor to system planning, operation, and economic assessment.
Comprehensive characteristics of electrochemistry energy storages. As shown in Table 1, LIB offers advantages in terms of energy efficiency, energy density, and technological maturity, making them widely used as portable batteries.
Thus, comprehensively evaluating the technical characteristics, economics and sustainability of an EST under various scenarios has great significance for demonstrating the viability of an EST for large-scale energy storage [10, 11, 20].
Notably, discussions have predominantly centered on the economic viability of energy storage applications within integrated energy systems (IES), comparative economic analyses of various EST, and cost analysis and optimization of emerging EST, which are specifically overviewed bellow.
