What is energy storage?

Basics of Energy Storage Energy storage refers to resources which can serve as both electrical load by consuming power while charging and electrical generation by releasing power while discharging. Energy storage comes in a variety of forms, including mechanical (e.g., pumped hydro), thermal (e.g., ice/water), and electrochemical (e.g., batteries).

What is a battery energy storage system?

Battery energy storage systems (BESS) are charged and discharged with electricity from the grid. Lithium-ion batteries are the dominant form of energy storage today because they hold a charge longer than other types of batteries, are less expensive, and have a smaller footprint. Batteries do not generate power; batteries store power.

How do electrochemical batteries store energy?

Electrochemical batteries store energy by separating positive and negative charges in rechargeable cells. Different types of electrochemical battery storage technology include: Government and developers are investing substantially in the creation of huge lithium-ion batteries to store energy for times when supply outstrips demand.

Are energy storage systems safe?

Within a given technology (e.g., lithium ion), there can be large differences in system performance based on the specific cell chemistry. For all of the technologies listed, as long as appropriate high voltage safety procedures are followed, energy storage systems can be a safe source of power in commercial buildings.

What are the different types of energy storage?

Energy storage comes in a variety of forms, including mechanical (e.g., pumped hydro), thermal (e.g., ice/water), and electrochemical (e.g., batteries). Recent advances in energy storage, particularly in batteries, have overcome previous size and economic barriers preventing wide-scale deployment in commercial buildings.

How does energy storage work?

Energy storage can smooth both the momentary, and longer term fluctuations in power from intermittent renewable resources. There are currently no revenue streams associated with smoothing the short term fluctuations in power since the electric grid provides these same services at no cost.
