We note that despite the higher facial cost of Lithium technology, the cost per stored and supplied kWh remains much lower than for Lead-Acid technology. The reason is related to the intrinsic qualities of lithium-ion batteries but also linked to lower transportation costs.
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.
In summary, the total cost of ownership per usable kWh is about 2.8 times cheaper for a lithium-based solution than for a lead acid solution. We note that despite the higher facial cost of Lithium technology, the cost per stored and supplied kWh remains much lower than for Lead-Acid technology.
As expected, on a $/kWh basis, longer duration batteries have a lower capital cost, and on a $/kW basis, shorter duration batteries have a lower capital cost. Figure 7 also demonstrates why it is critical to cite the duration whenever providing a capital cost in $/kWh or $/kW. Figure 7.
