Some long-duration energy storage (LDES) technologies are already cost-competitive with lithium-ion (Li-ion) but will struggle to match the incumbent''s cost reduction potential. That''s according to BloombergNEF
In non-China markets, installed LDES system costs were 54% higher for thermal energy storage, 66% higher for flow batteries and 68% higher for compressed air storage,
The global energy storage market almost tripled in 2023, the largest year-on-year gain on record. Growth is set against the backdrop of the lowest-ever prices, especially in China where turnkey energy
Prices for a fully installed, four-hour, utility-scale storage system this year range from $235 to $446/kWh, based on responses to BloombergNEF''s industry survey. The wide range highlights the number of variables that
The battery storage technologies do not calculate levelized cost of energy (LCOE) or levelized cost of storage (LCOS) and so do not use financial assumptions. Therefore, all parameters are the same for the research and
Projected Utility-Scale BESS Costs: Future cost projections for utility-scale BESS are based on a synthesis of cost projections for 4-hour duration systems as described by (Cole and Karmakar, 2023). The share of energy

Therefore, to account for storage costs as a function of storage duration, we apply the BNEF battery cost reduction projections to the energy (battery) portion of the 4-hour storage and use the (Cole et al., 2021) summary for
New York, December 10, 2024 – Battery prices saw their biggest annual drop since 2017. Lithium-ion battery pack prices dropped 20% from 2023 to a record low of $115 per kilowatt-hour, according to analysis by research

Trina Storage has once again secured a top spot in BloombergNEF''s (BNEF) Energy Storage System Cost Survey 2024, acknowledged for its cutting-edge products,
The domination of lithium-ion batteries in energy storage may soon be challenged by a group of novel technologies aimed at storing energy for very long hours.
Around the beginning of this year, BloombergNEF (BNEF) released its annual Battery Storage System Cost Survey, which found that global average turnkey energy storage system prices had fallen 40% from 2023 numbers to US$165/kWh in 2024.
Cost data for most technology groups came from projects deployed globally between 2018 and 2024. At $232/kWh, thermal energy storage was the cheapest technology group, followed by compressed air storage. At $643/kWh, gravity storage had the highest average global capex cost, BNEF said.
The scale of the reduction suggests that in addition to the falling cost of batteries—BNEF’s recent Lithium-ion Battery Price Survey found that battery pack prices fell 20% year-on-year to 2024, again the biggest drop recorded to date—energy storage system providers are working on cost reduction in other areas, Kikuma said.
At $643/kWh, gravity storage had the highest average global capex cost, BNEF said. In non-China markets, installed LDES system costs were 54% higher for thermal energy storage, 66% higher for flow batteries and 68% higher for compressed air storage, BNEF said.
Isshu Kikuma says that although BNEF didn’t include the possibility of increased costs for fire suppression or prevention equipment into its forecasts, it is a topic the analysts have discussed with survey participants.
In 2024, the global energy storage is set to add more than 100 gigawatt-hours of capacity for the first time. The uptick will be largely driven by the growth in China, which will once again be the largest energy storage market globally.
