Energy Storage Costs: Trends and Projections
This discussion aims to elucidate the implications of evolving energy storage costs and their impact on the energy landscape through an energy systems approach.
The cost of large-scale energy storage systems consists of recycling cost (C 1), equipment cost (C 2) (power converters and management system cost), integration cost (C 3), replacement cost (C 4), and operational maintenance cost (C 5). The formulas for each cost component are as follows: 1) Recycling Cost (1) C 1 = C B ⋅ E N 1
With the widespread use of new energy electric vehicles, there will be a large number of spent power batteries available in the future. Therefore, the cascade utilization in the field of energy storage systems is expected to become the trend of industry development.
They are priced according to five different power ratings to provide a relevant system comparison and a more precise estimate. The power rating of an energy storage system impacts system pricing, where larger systems are typically lower in cost (on a $/kWh basis) than smaller ones due to volume purchasing, etc.
And it is an industry consensus to promote the sustainable development of the cascade utilization industry of spent power batteries. In this work, the cascade utilization technologies of spent power battery in the field of energy storage are systematically described.
