Long-duration tech still outcompeted by lithium, trade group advocates for ‘valuing diversity’
Key Takeaway
While LDES deployment is growing, lithium-ion's market dominance means alternative LDES technologies require policy intervention to achieve competitive viability and diversify grid storage options.
AI Summary
- •Global long-duration energy storage (LDES) deployments experienced significant growth in 2025, indicating increasing market demand.
- •Newer, non-lithium-ion LDES technologies are currently being outcompeted by incumbent lithium-ion solutions, primarily on cost and market maturity.
- •A trade group is advocating for policies that 'value diversity' in storage technologies, suggesting potential future regulatory support or incentives for alternative LDES.
- •For developers and large loads, this implies Li-ion remains the dominant and most cost-competitive storage option for now, but policy changes could soon create a more level playing field for diverse LDES solutions.
