What is electrical energy storage (EES)?

Electrical Energy Storage (EES) refers to systems that store electricity in a form that can be converted back into electrical energy when needed. 1 Batteries are one of the most common forms of electrical energy storage.

What is the US energy storage monitor?

The US Energy Storage Monitor is offered quarterly in two versions– the executive summary and the full report. The executive summary is free, and provides a bird's eye view of the U.S. energy storage market and the trends shaping it.

What is the economic value of energy storage?

One study found that the economic value of energy storage in the U.S. is $228B over a 10 year period. 27 Lithium-ion batteries are one of the fastest-growing energy storage technologies 30 due to their high energy density, high power, near 100% efficiency, and low self-discharge 31. The U.S. has 1.1 Mt of lithium reserves, 4% of global reserves. 32

Where can I find energy storage industry data?

It is available individually each quarter or as part of an annual subscription. The quarterly reports from ACP and Wood Mackenzie are routinely cited by hundreds of media outlets as the authoritative source of energy storage industry data.

What resources are available for energy storage?
