By 2041, The Average Installed Cost Of Utility-scale Battery Storage Systems Worldwide Will Fall Below 100 Dollars Per KWh, Less Than Half Of The 2020 Level.

The 2041 Vision for Grid Scale Battery Storage Costs

Grid scale battery storage systems have become a critical technology for balancing the intermittent output of renewable energy sources and enhancing the reliability of the electricity grid. In 2020, the average installed cost of these systems was approximately 280 dollars per kWh. Data published by institutions such as NREL and IEA indicate that costs will decline significantly over the next two decades. This forecast suggests that by 2041, the average installed cost will fall below 100 dollars per kWh. Several fundamental dynamics underlie this cost reduction. The learning curve effect ensures that unit costs decrease at a certain rate with every increase in production volume. Economies of scale allow fixed costs to be spread over a wider base through larger factories and higher production volumes. Increasing raw material efficiency enables the use of fewer critical materials such as lithium, nickel, and cobalt, or their recycling. Together, these three factors could go beyond the 180 dollar level projected for 2040 and point to below 100 dollars in 2041. According to NREL data, the expected decline between 2020 and 2040 is around 36 percent. However, technological development may follow an accelerating rather than a linear curve. New chemistries such as solid state batteries, sodium ion technologies, and flow batteries could push costs even lower. Additionally, policy incentives, carbon pricing, and corporate demand could accelerate investments and steepen the learning curve. To verify this forecast, a reliable institution such as NREL or IEA must confirm in a 2041 grid scale battery storage cost report that the average installed cost per kWh is below 100 dollars. The following conditions could support achieving this target.

• Annual production capacity reaching the terawatt hour scale.
• Lithium and nickel recycling rates exceeding 90 percent.
• Widespread incentives and standards specifically for grid scale storage.

In conclusion, an average installed cost below 100 dollars per kWh in 2041 appears to be an achievable target. This decline will accelerate the adoption of energy storage and strengthen the integration of renewable energy into the grid.
