Grid energy storage track

How can energy storage help the electric grid?

Three distinct yet interlinked dimensions can illustrate energy storage’s expanding role in the current and future electric grid—renewable energy integration, grid optimization, and electrification and decentralization support.

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.

Is pumped-storage hydropower catching up with grid-scale batteries?

Pumped-storage hydropower is still the most widely deployed storage technology, but grid-scale batteries are catching up The total installed capacity of pumped-storage hydropower stood at around 160 GW in 2021. Global capability was around 8 500 GWh in 2020, accounting for over 90% of total global electricity storage.

Why is a data-driven assessment of energy storage technologies important?

This data-driven assessment of the current status of energy storage technologies is essential to track progress toward the goals described in the ESGC and inform the decision-making of a broad range of stakeholders.

What drives energy storage growth?

Energy storage growth is generally driven by economics, incentives, and versatility. The third driver—versatility—is reflected in energy storage’s growing variety of roles across the electric grid (figure 1).

Are lithium phosphate batteries a good choice for grid-scale storage?

Based on cost and energy density considerations, lithium iron phosphate batteries, a subset of lithium-ion batteries, are still the preferred choice for grid-scale storage.
