Energy Storage System

Energy storage is a critical issue in contemporary society. However, many people believe that it might not be possible to store it effectively. Energy storage is vital because it makes renewable energy economically viable and it enables efficient use of existing generation assets. Most institutions require energy for their daily operations which makes it important for us to explore more on energy storage. So let’s get into it.

What is the energy storage system

Energy storage systems are a set of technologies and methods used to store various forms of energy. Some of these energy storage forms may include solid-state batteries, thermal, pumped hydropower, compressed air, flywheels, and flow batteries. Therefore, the choice of energy storage technology is dictated by the integration within the system, economics, applications and the availability of resources. It is essential for the integration of renewable energy technologies.

Energy storage systems have been expensive on a large scale. However, some innovations facilitate storage and improve technology applications. Energy storage systems integrate renewables by providing grid services to meet high demands. Therefore utilities and system operators will need energy storage technologies to make energy more sustainable, secure and economical.

What is used for Energy storage

Energy storage facilitates the quality of power supply for achieving the demand. The attractive perception of what is used for energy storage is that it allows for numerous applications. This allows for a steady efficient flow of power. Therefore, electricity can be generated from stored energy which will then be fed on the great so that it can be supplied to the consumers.

What is the most efficient way to store energy

Energy storage is essential to balance between generation and consumer demand to regulate fluctuations in the demand. Therefore energy can be stored in the following ways:

Thermal energy storage

When there is low demand electricity can be used to freeze water stored in tanks hence this is among the cheapest energy storage.


These are rechargeable batteries that are capable of storing energy until when it is needed. These batteries can use lithium-ion and lead-acid or any other latest battery technologies.


The flywheel is a type of rotary that is used to accelerate a flywheel which is conserved as kinetic energy until when it is needed. Some of them use magnetic bearings which can attain a speed of 60,000 revolutions which can be used to turn a generator.

Compressed Air

Electricity can be used to compress and store it in caverns. Therefore the pressurized air can meet the rising demands by being used as a source of energy using the turbine generator.

Pumped Hydroelectric
Electricity can be used to pump water which is held in a reservoir. Therefore when there is demand a turbine can be used to generate energy to meet the demands as it flows through the generator for processing electricity.

What are the benefits of energy storage

The following are the benefits of energy storage:

Saves money

Energy storage reduced cost by providing frequency regulation by storing low-cost energy hence it saves your money. It saves on operational costs which saves money for the consumers.

Improves Reliability

Having energy storage I a backup which makes it more reliable. This ensures uninterrupted power to consumers anytime that you will need it.

Reduces Environment Impacts

Electricity can be stored for later use which reduces the use of greenhouses which is not good for the environment. It uses no- carbon resources which can damage the environment.

Demand charge Reduction

Commercial institutions should be given charges on their energy bills to reduce demand charges by accounting for half of the total bill. The software can be used to track facility load so that it can reduce charges during peak demand.

How does energy storage work and distribute energy

Energy storage is useful on the grid-scale which facilitates its distribution. It works by balancing the load which generates the capacity to be used effectively by shifting energy consumption. This is to ensure power quality management to control voltage to meet the demands. The energy storage projects vary with new applications ranging from thermal, mechanical and electrical depending on energy storage.

Therefore, this allows energy delivery and consumption which helps in equipment failures and power outages to avoid inconveniences. Distribution of stored energy is dependent on the balance of power supply to meet the demands instantaneously which makes power networks efficient and resilient.
