The energy storage asset class puts a single label on a dizzying variety of technologies and applications. It’s hard to compare a cavern full of pumped air with a lithium-ion battery, even if they perform similar functions. This makes it difficult to gauge progress across the entire industry. The financial analysts at Lazard make it easier with their Levelized Cost of Storage Analysis, the second annual instalment of which was released Thursday. They standardized costs for 10 prevailing storage technologies to show how they stack up for 10 particular use cases. The picture that emerges is of an ecosystem of technologies rapidly trending down in cost, especially for the larger-scale projects. The old grid-scale stalwarts, pumped hydro and compressed air, still beat the newcomers on cost, but the advanced technologies are closing the gap quickly, and they can operate in many more settings.
