Energy storage technology adjustment information

How can research and development support energy storage technologies?

Research and development funding can also lead to advanced and cost-effective energy storage technologies. They must ensure that storage technologies operate efficiently, retaining and releasing energy as efficiently as possible while minimizing losses.

Why did we select energy storage technologies?

We selected these technologies because they met our definition of utility-scale energy storage, were used on the grid as of March 2022, and maturity level. Based on these criteria, we did not include technologies such as hydrogen, liquid air energy storage, or concentrated solar thermal in our review.

How does energy storage technology affect the adoption of energy storage technologies?

The adoption of an energy storage technology may be impacted by system need and duration. Technologies such as lithium-ion batteries and flywheels can provide shorter duration capacity—from seconds to approximately 4 hours—that is useful for applications like arbitrage and frequency regulation.

How long do energy storage technologies last?

Energy storage technologies have different uses depending on their durations, which can be from seconds to many days. The adoption of an energy storage technology may be impacted by system need and duration.

How can energy storage standards be adopted more quickly?

As storage technologies mature, codes and standards could be adopted more quickly through proactive engagement between utilities, storage facility owners or operators, and standard-setting organizations. Education and workforce training programs could help people operate energy storage systems more safely.

How does the federal government support energy storage technology?

The federal government has driven the technical development of energy storage technologies and incentivized developers through financial support of early demonstration projects, improving market rules, and a series of grant programs.
