Are battery storage costs based on long-term planning models?
Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.
Does battery storage cost reduce over time?
The projections are developed from an analysis of recent publications that include utility-scale storage costs. The suite of publications demonstrates wide variation in projected cost reductions for battery storage over time.
What are battery cost projections for 4-hour lithium-ion systems?
Battery cost projections for 4-hour lithium-ion systems, with values relative to 2024. The high, mid, and low cost projections developed in this work are shown as bold lines. Published projections are shown as gray lines. Figure values are included in the Appendix.
How much does storage cost in 2035?
By definition, the projections follow the same trajectories as the normalized cost values. Storage costs are $147/kWh, $234/kWh, and $339/kWh in 2035 and $108/kWh, $178/kWh, and $307/kWh in 2050. Costs for each year and each trajectory are included in the Appendix, including costs for years after 2050. Figure 4.
The cooling system of wind power equipment is relatively complex, mainly including the following types: in units containing a gearbox, the gearbox is equipped with a special gear oil cooling system; the generator itself is equipped with a cooling system, such as a cooling fan, natural air cooling, etc.; in units containing a converter system, the converter system also has a corresponding cooling system with various cooling methods, including air cooling, water cooling, etc.; to solve the problem of excessive temperature in the wind turbine nacelle, the entire machine has a cooling system, such as an overall air cooling system using the chimney effect; in addition, there are cooling systems for other equipment.
