When it comes to selecting an energy storage system, there comes a wide variety of options along. Moreover, as the technology advances, it updates the existing storage systems on the shelves. This introduces newer and more efficient systems to choose from as they consider the faults in the existing system.

Not only is the technology advancing, but its demand is also increasing overall. This surge in demand makes it even more necessary to identify the energy storage system needed. So let’s dive right into the types.

What is an Energy Storage System?

Energy storage is the process of capturing energy generated at one point and storing it for later use to alleviate energy demand-supply mismatches. An accumulator, sometimes known as an EV battery, is a gadget that accumulates power. Radiation, chemical, gravitational potential, electric charge, power, increased temperature, hidden heat, and translational energy are all examples of energy.

Short-term power storage is provided by some systems, while others provide long-term energy storage. Hydroelectric dams, both traditional and enhanced, presently monopolize bulk power retention. System energy storage refers to techniques for storing energy on a large scale inside a power grid.

What are different types of Energy Storage Systems?

When it comes to EV’s, PHEV’s, HEV’s, here are the types of energy storage systems that one should know about.

     1. Lithium-Ion Batteries

Because of its high energy per unit mass when compared to other electronic energy storage devices, lithium-ion batteries are now utilized in most consumer electronics devices such as mobile phones and computers. They also feature a high power-to-weight ratio, strong high performance, and minimal self-discharge.

The Lithium-Ion Battery Recycling Prize, sponsored by the US Department of Energy, aims to find methods for collecting, classifying, storing and transferring abandoned lithium-ion batteries for potential recycling and resource extraction. Lithium-ion batteries are used in most of today’s PHEVs and EVs; however, the precise composition varies from electronic goods cells. There is continuing science and technology to lower their fairly expensive pricing, prolong their usable life, and solve overheating safety issues.

     2. Nickel-Metal Hydride Batteries

Nickel-metal hydride batteries, often used in computers and hospital instruments, provide adequate higher capacitance and specific energy. Nickel-metal hydride batteries have a significantly longer life cycle than lead-acid batteries, and they are also much safer and more resistant to misuse.

In HEVs, these batteries have been frequently employed. However, Nickel-metal hydride batteries have several problems, including massive cost, significant self-discharge and heat production at extreme temps, and the necessity to regulate hydrogen loss.

     3. Lead-Acid Batteries

Lead-acid batteries may be engineered to be high-capacity while being affordable, safe, and dependable. However, their application is limited by their low specialized output, limited cold-temperature efficiency, and short cycle and lifespan. Improved high lead-acid batteries are now being produced; however, they will only be utilized for auxiliary loads in commercially accessible electric cars.

    4. Storage of compressed air

When used in combination with a wind farm, it sucks in air and creates a high-pressure system in a sequence of huge underground chambers. When wind speeds slowly or consumption for electricity increases, compressed air, usually combined with a little natural gas, is produced to power turbines or generators.

    5. Rail-based advanced energy storage

Advanced Train Energy Storage is a technology that uses rail carriages to store power and was developed by a California firm. First, excess grid energy is used to power axle-drive engines on rail carriages, which push freight uphill and also against the gravitational pull to an assigned location.

Then, the rail trains travel back downwards to harvest electricity from the network. This time, the wheels serve as mini-generators, recharging the grid with power.

      6. Ultracapacitors

Between an electrode and an electrolyte, ultra-capacitors store electricity in a polarized liquid. As the surface coverage of a liquid rises, so does its storage capacity. Ultra-capacitors can assist cars to recover braking energy and provide additional power when acceleration and uphill are ascending. Because they assist electrochemical EV battery balance load power, they might be helpful as one of the supplementary energy storage systems in electric cars.

       7. Energy Storage Using Flywheels

Flywheel energy storage devices transform electricity into kinetic energy stored in the manner of spinning wheels. To minimize energy loss, the blades are maintained in a frictionless vacuum by magnetism, and when power is required, the spinning may be slowed in a manner that produces energy.

This system has several advantages over conventional energy storage devices, such as little administration, extended life, and lesser ecological effect.

       8. Hydroelectricity from Pumped Storage

Pumped-storage hydroelectricity is a common kind of power storage generally used to store surplus power from the grid. Electric power from the grid pumps water up into a pond or lake whenever demand is low. Water is permitted to flow from a higher reservoir to a bottom reserve when consumption spikes. As the water flows through lower reserves, it passes through turbines generating electricity.

       9. Energy Storage Using Liquid Air

Excess grid power is used to chill airflow to the extent where it forms a liquid, which is known as Liquid Air Energy Storage, or LAES. Next, the liquid air is turned back to gas by exposing it to the ambient atmosphere or using waste heat to recover power from the device. The turbines are then powered by the increasing gasses.

      10. Redox Flow Batteries are a type of battery that uses a redox

Redox flow batteries, unlike lithium-ion batteries, which are solid form batteries, store surplus grid power in liquid electrolyte solutions through electrochemical reductions and oxidation processes. Redox batteries have a significant advantage over lithium-ion as well as other solid-state devices in terms of versatility.

Energy storage systems allow energy to be collected and discharged during sunny and windy seasons. Although it may appear to be a straightforward idea, energy storage may be accomplished in a variety of ways, as mentioned above.
