Applications of Energy Storage Technology

Energy1. Energy is the potential of a physical system to perform work. (A common unit of work is foot-pound—the amount of energy needed to lift one pound up a distance of one foot.) Energy exists in several forms such as electromagnetic radiation ... storage provides a myriad of beneficial services and cost savings to our electricAn adjective meaning “needing electricity to operate” such as electric motor or wire. IEEE: Containing, producing , arising from, actuated by or carrying electricity. grid, and companies are deploying storage technologies for a number of different purposes.  Large scale energy storage also allows today's electrical1. An adjective meaning “pertaining to electricity”. Electrical Engineer. 2. Related to, pertaining to or associated with electricity but not having its properties or characteristics. system to run significantly more efficiently, and that greater efficiency means lower prices, less emissions and more reliable powerThe rate at which energy is generated, converted, transmitted, distributed or delivered..

Traditional energy sources - like coal and natural gas power plants - have to be turned on and off as demand1. The rate at which electric energy is delivered to or by a system or part of a system, generally expressed in kilowatts or megawatts, at a given instant or averaged over any designated interval of time. 2. The rate at which energy is being used by... fluctuates, and are almost never operating at peak performance. This means that energy not only costs more, but pollutes more, than is necessary to meet our energy needs. And the slow ramp up time of these bulk generationThe manner in which electricity is generated. The electricity that flows through California facilities means they cannot respond to spikes in demand in real time, potentially leading to brownouts and poor power qualityA measure of the level of voltage and/or frequency disturbances..

With the widespread adoption of renewable energy resources, energy storage is equally useful. As is often noted, these energy sources are intermittent in nature, producing energy when the sun is shining and the wind is blowing. By storing the energy produced and delivering it on demand, these clean technologies can continue to power our grid even when the sun has set and the air is still - leveling out jumps in output to create a continuous, reliable stream of power throughout the day.

But warehousing energy from diverse resources for use at a different time is only one of the many applications of energy storage. Storage technologies also improve the quality of power through frequency regulation, allows companies to produce power when it is cheapest and most efficient, and provide an uninterruptible source of power for critical infrastructure and services.

In this section, you can learn more about the ways that the value of energy storage is being realized commercially.
