How many GW of energy storage are there in 2022?

By the end of 2022 about 9 GW of energy storage had been added to the U.S. grid since 2010, adding to the roughly 23 GW of pumped storage hydropower (PSH) installed before that. Of the new storage capacity, more than 90% has a duration of 4 hours or less, and in the last few years, Li-ion batteries have provided about 99% of new capacity.

Where can I find a report on lithium ion batteries?

This report is available at no cost from the National Renewable Energy Laboratory (NREL) at Denholm, Paul, Wesley Cole, and Nate Blair. 2023. Moving Beyond 4-Hour Li-Ion Batteries: Challenges and Opportunities for Long(er)-Duration Energy Storage. Golden, CO: National Renewable Energy Laboratory. NREL/TP-6A40-85878.

Will a fifth hour of battery storage cost more than 4 hours?

value for a fifth hour of storage (using historical market data) is less than most estimates for the annualized cost of adding Li-ion battery capacity, at least at current costs.25 As a result, moving beyond 4-hour Li-ion will likely require a change in both the value proposition and storage costs, discussed in the following sections.

Could a battery energy storage system democratize access to electricity?

Moreover, battery energy storage systems (BESS) could help democratize access to electricity. “In remote areas, such as in the mountains or in poorer countries, coupling renewable power with storage is a must for bringing energy to more people,” Knauth says. Yet energy storage systems have their hurdles.

Can Li-ion batteries be moved beyond 4 hours?

Moving beyond 4-hour duration also raises the question of the possibility of moving beyond Li-ion batteries as the (nearly) exclusive stationary energy storage technology currently being deployed.

Why do we need battery energy storage systems?

Battery energy storage systems (BESS) have become a solution to prevent surpluses from being lost and to cover the intermittence of renewable energy. “We need energy storage solutions to make them permanent,” says researcher and electric battery expert Philippe Knauth in an interview for bbva.com.
