The comparison of costs between lithium-ion batteries and other energy storage technologies over the next decade highlights several trends and projections:
Lithium-Ion Batteries
- Cost Trends: Lithium-ion battery pack prices have experienced significant drops, with a record low of $115/kWh reported by BloombergNEF in late 2024. This decline is driven by factors such as manufacturing overcapacity, economies of scale, and the adoption of lower-cost chemistries like lithium-iron-phosphate (LFP).
- Market Dynamics: The global market for lithium-ion battery cells is projected to reach over $400 billion by 2035, reflecting a strong demand for EVs and renewable energy storage. However, low prices may challenge new entrants and affect industry profitability.
- Future Outlook: Prices are expected to continue decreasing due to ongoing R&D and manufacturing improvements. Next-generation technologies will play a crucial role in further price reductions.
Other Energy Storage Technologies
- Long-Duration Energy Storage (LDES): Technologies like thermal energy storage and compressed air storage are becoming more competitive for discharge durations longer than eight hours. For example, thermal energy storage costs about $232/kWh, which is lower than the average cost for lithium-ion batteries ($304/kWh for four-hour systems).
- Regional Variations: Costs vary significantly by region, with China often having lower costs due to economies of scale and favorable policies. In non-China markets, costs for LDES technologies are significantly higher.
- Compressed Air Storage: This technology is cost-competitive with lithium-ion in specific regions but faces challenges in achieving economies of scale similar to those of lithium-ion batteries.
Comparison Table
| Energy Storage Technology | Current Cost (2024) | Future Trends |
|---|---|---|
| Lithium-Ion Batteries | $115/kWh (global average for pack prices) | Expected to decrease further with improvements in technology and manufacturing. |
| Thermal Energy Storage | $232/kWh | Costs are competitive for long-duration applications but vary by region. |
| Compressed Air Storage | $293/kWh | Economies of scale and policy support needed to match lithium-ion costs. |
| Flow Batteries | Higher than lithium-ion, exact cost varies by project. | Non-lithium technologies face challenges in achieving similar economies of scale to lithium-ion. |
Over the next decade, while lithium-ion batteries will continue to be a dominant player due to their widespread adoption and decreasing costs, other technologies like thermal and compressed air storage will become more competitive for specific applications, particularly long-duration energy storage. However, non-lithium technologies may struggle to replicate the economies of scale achieved by lithium-ion batteries.
