In most places, the grid connects hundreds or more of these places to a vast network of wires and equipment. Electric current can travel along many paths within the network. Power also can flow either way along wires. Equipment tells the current where to go. Two-way wires also allow the use of alternating current, or AC.

Emphasis is placed on storage technologies that are connected to a larger energy system (e.g. electricity grid), while a smaller portion of the discussion focuses on off-grid storage applications. This focus is complemented by a discussion of the existing technology, policy, and economic barriers that hinder energy storage deployment.

How does storage help us balance the grid? Energy storage allows us to move energy through time, capturing it when we have too much and saving it for when we don''t have enough. When we have excess electricity, perhaps on a really windy day, we don''t want the extra energy to go to waste. If we can store the electricity to use later, when ...
