Can a water treatment facility repurpose a chemical for energy storage?

A commonplace chemical used in water treatment facilities has been repurposed for large-scale energy storage in a new battery design by researchers at the Department of Energy's Pacific Northwest National Laboratory. The design provides a pathway to a safe, economical, water-based, flow battery made with Earth-abundant materials.

Which energy storage technologies are included in the 2020 cost and performance assessment?

The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.

Why is energy storage more expensive than alternative technologies?

High capital cost and low energy density make the unit cost of energy stored ($/kWh) more expensive than alternatives technologies. Long duration energy storage traditionally favors technologies with low self-discharge that cost less per unit of energy stored.

Are battery energy storage systems a good idea?

Their advantage is that they can be built at any scale, from the lab-bench scale, as in the PNNL study, to the size of a city block. In the near term, grid operators are looking to locate battery energy storage systems (BESS) in urban or suburban areas near energy consumers. Often, city planners must grapple with consumer safety concerns.

Are Li-ion batteries the future of energy storage?

Li-ion batteries are deployed in both the stationary and transportation markets. They are also the major source of power in consumer electronics. Most analysts expect Li-ion to capture the majority of energy storage growth in all markets over at least the next 10 years , , , , .

What is long duration energy storage (LDEs)?

Long Duration Energy Storage (LDES) is a key option to provide flexibility and reliability in a future decarbonized power system. A variety of mature and nascent LDES technologies hold promise for grid-scale applications, but all face a significant barrier—cost.
