What is an energy storage system?

An energy storage system captures energy produced at one time for use at a later time. It helps balance supply and demand.

Name three types of energy storage technologies.

Lithium-ion batteries, pumped hydroelectric storage, and flywheels.

How does pumped hydroelectric storage work?

It stores energy by pumping water to a higher elevation during low demand and releasing it to generate electricity during peak demand.

What are the advantages of lithium-ion batteries for energy storage?

Lithium-ion batteries have high energy density, longer life span, and lower self-discharge rates compared to other batteries.

Explain how thermal energy storage works.

Thermal energy storage saves heat or cold for later use, often employing materials like water, molten salts, or phase-change materials.
