Does grid energy storage have a supply chain resilience?

This report provides an overview of the supply chain resilience associated with several grid energy storage technologies. It provides a map of each technology’s supply chain, from the extraction of raw materials to the production of batteries or other storage systems, and discussion of each supply chain step.

Why does the United States lag in grid storage?

Reliance on other countries for critical raw and refined materials, components, and products—The United States lags Asia, and especially China, in the manufacture and supply of materials, components, and end products for grid storage.

Are EV batteries repurposed for grid storage?

Faessler (2021) analyzed the European market for EV batteries repurposed for grid storage and found more than 20 sites where EV batteries were repurposed for stationary applications across Europe.

What are the barriers to energy storage?

An additional barrier is the difficulty in obtaining capital due to the lack of “Tier 1” suppliers or standardization of offerings and long-term off-take contracts, especially for standalone energy storage [ (Plautz, 2021); (Walters, 2021)].

Which technologies are commercially available for grid storage?

Several technologies are commercially available or will likely be commercially available for grid storage in the near-term. The technologies evaluated provide storage durations that range from hours to days and response times of milliseconds to minutes. Four families of battery technologies and three LDES technologies are evaluated.

Can a flow battery be used for grid storage?

Development of other technologies is critical to meet the varied demands of grid storage. This is especially true for LDES technologies as current PSH and CAES technologies have geographical limitations. Technologies such as the flow battery may help in this regard.
