Energy storage market intelligence
Battery deployments, grid-scale projects, and emerging long-duration technologies.
Energy storage is the enabling technology of the electricity transition. As solar and wind reach dominant shares of generation capacity, the need for flexible, fast-responding, and increasingly long-duration storage is growing exponentially. Each application has different duration, cycling, and cost requirements — and different technology winners.
Lithium-ion dominates the short-to-medium duration segment, but the technology landscape is diversifying. LFP chemistry is displacing NMC in stationary applications. Sodium-ion is emerging as a low-cost alternative. For durations beyond four hours, competing technologies — vanadium and iron flow batteries, compressed and liquid air, gravity systems, iron-air batteries, and green hydrogen — are vying for market share.
Delphidata tracks energy storage across all technology types, durations, and applications. Our knowledge graph connects storage projects to the generation assets they support, the grid infrastructure they connect to, the battery cell manufacturers and system integrators that build them, and the market mechanisms that provide revenue.
