Energy Storage

The first battery was believed to have been invented somewhere in Ancient Mesopotamia, during either the time of the Parthian or Sasanian Empires, and is commonly known as the Baghdad Battery. The time period this encompases stretches from approximately the year 150 BC to 650 AD, long before historians believed human beings understood how to harness the power of electricity in any form. This was the first known example of any kind of energy storage technology, what is now currently one of the most important areas of scientific development being worked on today. The usage of the word battery is far more modern than the Baghdad Battery, having been coined to describe a group of electrical devices by Benjamin Franklin in 1748. Today, the term encompasses any kind of device designed for the purpose of storing energy for use in the future. The term accumulator is also used to describe these devices, but it is not a frequently used part of the common vernacular. The main purpose of energy storage devices is to allow us to convert energy from forms that are difficult to store in the long term into those that do so more easily and cheaply. The most widely used and economically sustainable form of energy storage today is the use of hydroelectric dams. As the world’s supply of fossil fuels and other non-sustainable sources of energy are steadily being depleted, finding more efficient and inexpensive methods to store energy is crucial to our society.
