Overview of Long Duration Energy Storage (LDES)

This report examines the pathways for commercial liftoff of LDES technologies, defined as achieving a self-sustaining market by 2030. LDES plays a critical role in decarbonizing the power sector by providing flexibility and reliability for variable renewables, reducing grid expansion costs, enhancing resilience, and diversifying energy storage supply chains.

Key Findings

• Objectives: The report aims to inform decision-makers on LDES commercialization, supporting technologies like mechanical, thermal, and electrochemical storage to meet decarbonization goals by 2050.

• Technology Landscape: LDES technologies include inter-day and multi-day/week systems, with mechanical storage being the most mature. Key challenges involve reducing costs by 45–55% (e.g., capex and roundtrip efficiency improvements), advancing performance metrics, and overcoming lab-to-commercialization gaps.

• Economic and Investment Needs: Achieving liftoff requires significant investment, with $9–12B needed by 2030 and $230–335B by 2050. Equity and debt financing from government, utilities, venture capital, and tax credits are essential to attract private capital.

• Market Mechanisms: Regulatory reforms, such as compensation for resource adequacy ($50–75/kW-year) and market products valuing longer-duration storage, are needed to support business cases.

• Supply Chain Development: Annual manufacturing/deployment capacity must reach 3 GW by 2030 and 10–15 GW by 2035 to meet deployment targets, addressing raw material sourcing and workforce training.

• Workforce and Environmental Justice: Workforce development is critical due to engineering-intensive projects; environmental justice ensures benefits prioritize underserved communities, minimizing pollution and equity impacts.

• Pathways to Commercial Scale: Liftoff depends on concurrent advancements in technology, regulatory support, and supply chains. Deployment phases include demonstrations, scaling, and large-scale projects to achieve targets like 60–460 GW of LDES by 2050.

Conclusion

Stakeholders must prioritize collaborative actions, including targeted funding, policy reforms, and supply chain investments to accelerate LDES commercialization and achieve net-zero goals.
