How much will lithium-ion batteries cost in the coming years? Optimistic reports
The US National Renewable Energy Laboratory (NREL) has prepared a report in which it forecasts how the costs of capital expenditures in BESS will change in the years 2022–2050. According to the analysis, they may fall by up to 47% by 2030.
The National Renewable Energy Laboratory (NREL) has presented three distinct scenarios outlining potential developments in battery energy storage system costs. These scenarios are categorized as high, medium, and low variants, each projecting different trajectories for the coming years.
In the most pessimistic high-variant scenario, the next two years are anticipated to bring about further price increases. However, a more optimistic trend is predicted for the subsequent years, with price reductions of approximately 16% expected by the year 2030.
According to the low and medium projections, costs associated with battery energy storage systems are projected to decrease by 47% and 32% respectively by the year 2030. Across these different scenarios, it’s anticipated that by 2030, the prices of battery energy storage systems will range from USD 255/kWh (low), USD 326/kWh (medium), to USD 403/kWh (high).
These projections are founded on a comprehensive analysis of data and forecasts gathered from various sources, creating an overview of potential developments in battery energy storage costs. Notably, these cost estimates are focused on battery systems with a runtime of approximately 4 hours.
What will cause the price of battery energy storage systems to drop?
Indeed, lower production costs play a significant role in driving down the prices of battery energy storage systems (BESS). Among the key factors contributing to cost reductions are the battery cells and housings, which constitute a substantial portion of battery manufacturing expenses. These components’ costs account for at least half of the total battery cost.
The National Renewable Energy Laboratory (NREL) highlights the importance of considering battery life when assessing the economics of battery energy storage systems. When evaluating costs on a per kilowatt-hour (kWh) basis, batteries with longer run times tend to have lower capital costs. Conversely, when evaluating costs on a per kilowatt (kW) basis, batteries with shorter run times are generally more economical.
This distinction underscores the intricate relationship between battery run time, capacity, and cost, demonstrating that the specific requirements and use cases for battery energy storage systems should be considered when assessing their economic feasibility and potential savings.
Other reports are also optimistic
The forecasts provided by research firms suggest promising trends in the decline of battery energy storage system (BESS) costs. According to Fastmarkets, prices for batteries using lithium iron phosphate (LFP) cells are expected to reach $100/kWh by 2025. Similarly, nickel-manganese-cobalt (NMC) cell technology is projected to reach this cost threshold by 2027.
Additionally, BloombergNEF’s data highlights a recent 2% decrease in BESS costs over the last six months. This reduction is attributed to the declining price of lithium carbonate, which is recovering from previous record-high increases.
These trends suggest an optimistic outlook for the cost-effectiveness and affordability of energy storage technologies, making them more accessible and appealing for a wide range of applications, including renewable energy integration, grid stability, and more.
