Electricity storage is considered a key technology to enable low-carbon power systems. However, existing studies focus on investment cost. The future lifetime cost of different technologies (i.e., levelized cost of storage) that account for all relevant cost and performance parameters are still unexplored.
Here, we construct experience curves to project future prices for 11 electrical energy storage technologies. We find that, regardless of technology, capital costs are on a trajectory towards US$340 ± 60 kWh −1 for installed stationary systems and US$175 ± 25 kWh −1 for battery packs once 1 TWh of capacity is installed for each technology.

Cost projections are important for understanding this role, but data are scarce and uncertain.

The 2022 Cost and Performance Assessment provides the levelized cost of storage (LCOS). The two metrics determine the average price that a unit of energy output would need to be sold at to cover all
Despite investment cost reductions, underground hydrogen storage continues to incur high total costs per kWh discharged due to low roundtrip efficiency, suggesting its future outlook depends on
These insights can help guide research, policy and investment activities to ensure a cost-efficient deployment of electricity storage technologies for a successful transition to a secure and
The average cost per unit of energy generated across the lifetime of a new power plant. This data is expressed in US dollars per kilowatt-hour. It is adjusted for inflation but does not account for
This paper presents average values of levelized costs for new generation resources as represented in the National Energy Modeling System (NEMS) for our Annual Energy Outlook 2025 (AEO2025)
Hunter et al. [16] reviewed 14 potential energy storage or flexible power generation options, using both current and projected costs, and found many potential technologies that might be competitive as
This study presents a probabilistic economic and environmental assessment of different battery technologies for hypothetical stationary energy storage systems over their lifetime, with a
A detailed analysis of the cost breakdown shows that the proportion of the Capex and charging costs of EES projects are relatively high, while the Opex and tax costs are comparatively
Here, we construct experience curves to project future prices for 11 electrical energy storage technologies.
DOE''s Energy Storage Grand Challenge supports detailed cost and performance analysis for a variety of energy storage technologies to accelerate their development and deployment.
