Main Challenges in Scaling Long-Duration Energy Storage Technologies
Scaling long-duration energy storage (LDES) technologies before 2030 faces several significant challenges:
1. Cost Reductions
- Goal: To be competitive with alternative options, LDES technology costs need to decrease by 45–55% by 2028-2030.
- Challenge: Achieving substantial cost reductions in a short timeframe requires both technological advancements and economies of scale.
2. Market Signals and Revenue Mechanisms
- Challenge: The lack of long-term market signals and revenue mechanisms increases uncertainty for investors, making it difficult to secure funding for large-scale deployments.
- Solution: Implementing policies that provide clear market signals and improve risk-adjusted returns for investors can help mitigate this challenge.
3. Workforce Capacity
- Challenge: The deployment of LDES technologies is highly engineering and construction intensive, leading to workforce shortages as a major risk.
- Solution: Expanding training programs and adopting modular project deployments can help address workforce gaps.
4. Technological Maturity
- Challenge: Most LDES technologies, such as flow batteries and compressed air storage, are not yet mature enough for widespread deployment.
- Solution: Continued R&D investment is necessary to improve technological readiness.
5. Supply Chain and Scaling Production
- Challenge: Scaling production from less than 1 GW in 2022 to at least 3 GW by 2030 requires significant supply chain development and manufacturing capacity increases.
- Solution: Identifying leading technologies early and enabling repeat deployments can help reduce costs associated with supply chain formation.
6. Policy Support
- Challenge: Inconsistent policies across regions discourage large-scale investment in LDES.
- Solution: Encouraging policies similar to California’s, which mandates utilities to procure long-duration energy storage, can incentivize widespread adoption.
