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.

Do battery costs scale with energy capacity?

However, not all components of the battery system cost scale directly with the energy capacity (i.e., kWh) of the system (Feldman et al. 2021). For example, the inverter costs scale according to the power capacity (i.e., kW) of the system, and some cost components such as the developer costs can scale with both power and energy.

Can lithium ion batteries be adapted to mineral availability & price?

Lithium-ion batteries dominate both EV and storage applications, and chemistries can be adapted to mineral availability and price, demonstrated by the market share for lithium iron phosphate (LFP) batteries rising to 40% of EV sales and 80% of new battery storage in 2023.

Why is battery use growing in Africa?

Battery use is also growing in emerging market and developing economies outside China, including in Africa, where close to 400 million people gain access through decentralised solutions such as solar home systems and mini-grids with batteries in order to achieve universal access by 2030.

Do longer duration batteries have a lower capital cost?

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 6 (left) also demonstrates why it is critical to cite the duration whenever providing a capital cost in $/kWh or $/kW. Figure 6.

Does battery storage cost reduce over time?

The projections are developed from an analysis of recent publications that consider utility-scale storage costs. The suite of publications demonstrates wide variation in projected cost reductions for battery storage over time.
