The purpose is energy storage is to save energy so that you can use it at a future time.

The device used to store energy is generally called a battery, though it may also be referred to as an accumulator.

But we often see information online, and we’re asked about electrochemical storage. So we thought we’d take some time to explain to you what it is and why it is important.

There are a variety of examples actually, in addition to the rechargeable battery.

  • Pumped Hydro-Power – This uses large water reservoirs to create energy.
  • Solid State Batteries – This encompasses a variety of electrochemical storage options which includes capacitors and advanced chemistry batteries, too.
  • Thermal – This captures both cold and heat which can then create energy as required.
  • Flow Batteries – This stores energy directly providing a longer life and quicker responses.
  • Compressed Air Energy Storage – Harnesses compressed air to create energy.
  • Flywheels – This mechanical device harnesses electricity instantaneously upon energy from rotating wheels.

Going back to rechargeable batteries, which include lead-acid, lithium-ion, nickel-cadmium, and nickel metal hydride batteries, they are the perfect example of electrochemical storage. They have a lower cost over the long-term and are more environmentally friendly as they last longer and don’t require the same level of disposal as their temporary relatives do.

It’s a great example of something that may initially cost more than the alternative but will repay itself and more over time.
