What Does Green Energy Storage Cost in 2026?
Rising raw material prices, particularly for lithium and nickel, contribute to increased energy storage costs. Fixed operation and maintenance costs for battery systems are estimated at
The average price of lithium-ion battery packs is $152/kWh, reflecting a 7% increase since 2021. Energy storage system costs for four-hour duration systems exceed $300/kWh for the first time since 2017. Rising raw material prices, particularly for lithium and nickel, contribute to increased energy storage costs.
In 2025, lithium-ion battery pack prices averaged $152/kWh, reflecting ongoing challenges, including rising raw material costs and geopolitical tensions, particularly due to Russia's war in Ukraine. These factors have led to high prices for essential metals like lithium and nickel, impacting the production of energy storage technologies.
"Looking ahead, energy storage is likely to become a game changer for lithium, improving its fundamentals, but too high a price could undermine the economics of energy storage, keeping a lid on prices," Su said.
