For many kinds of renewable energy, energy isn’t used at the same time and place as it is collected. In some cases, it makes sense to route the energy, usually through “the gird” to locations where it can be used immediate. Another option is to store the energy until it is needed. For example, solar energy isn’t directly available to power streetlights and heat house during the night.
- compressed air storage
- batteries like zinc-bromine and vanadium redox
Storage cells – Alkaline Cells, Carbon-Zinc cells, Mercury cells, Zinc-Air cells, Silver Oxide cells, Lead Acid cells, Edison cells, Nicad cells, NiMH and Lithium cells are the most commonly used cells today.
fundamentals and principles of devices that “confine” energy into small cells.
Storage cells can also be classified as “wet cells”, which have liquid electrolytes; “dry cells”, which have electrolytes in the form of a paste; and “solid electrolyte” cells, which as their name indicates use a completely solid electrolyte.
