Our Guide To Battery Energy Storage Systems

If you are new to the world of energy storage or renewable energy as a whole, it is likely you have heard the phrase “battery energy storage system” (or BESS) but are unfamiliar with what these systems are.

A BESS is one of the most important components of renewable energy deployment in residential and commercial settings. These systems are imperative to making your solar panels or other electricity production systems work as efficiently as possible.

Throughout this blog, we are going to be discussing the different types of BESS and the advantages of having these storage systems for your business at your disposal.


What Is Battery Storage?

Battery energy storage is a form of energy storage that allows renewable energy to be stored and released when the power is needed most. For example, a solar panel arrangement will store some electricity from solar power in a battery storage system to be used when the sun is no longer out.

Battery storage is used in a multitude of ways throughout our everyday lives in devices such as mobile phones and electric cars. When they are charged, they will store the power given in the battery and will use this up as time goes on.

Having a BESS significantly reduces the amount of pressure the mains supply is required to undertake on a daily basis as it means that less power is needed for certain buildings, businesses and homes.

This means that the difference between supply and demand will be much smaller if more and more people choose to use battery storage systems and renewable energy sources. This will then reduce energy costs for the future in your home.


Types of Batteries

As you might expect, there are various forms of battery energy storage solutions for you to choose from depending on which you think best matches your needs. No matter which type of battery you opt for, you can be assured it will be excellent for storing clean energy.

These types of batteries are all used for different purposes, which means that they are not applicable to every situation. Read on to find out more about the different types of battery storage solutions available.


Solid-State and Flow Batteries

Solid-state batteries are applicable for all kinds of electrochemical storage technologies including various capacitors and multiple advanced chemistry batteries.

Both types of batteries utilise the electrolyte solution to store the energy. This is done to increase the total life cycle of the battery while providing users with rapid response times.


Compressed Air Energy Storage

Compressed air energy storage is achieved by creating energy reserves through the use of compressed air, as the name would suggest. The elastic potential energy from the air is used to improve the efficiency of gas turbines.

By compressing air during off-peak hours, the air can then be sorted in the underground caverns. The air is drawn from the storage and fired with natural gas through an air turbine to create electricity.


Mechanical Gravity Energy Storage

This type of system uses the force of gravity to generate electrical energy. When the energy from the system is needed, the concrete blocks are lowered down, using the pull of gravity to generate sustainable electricity.



Flywheels are mechanical devices that harness rotational energy and provide an instant stream of electricity to your business. The electricity in a flywheel is stored in the form of a rotating plate.

These forms of energy storage provide great benefits to the UK’s electricity grid helping with the supply and demand of the general public.


How Do Energy Storage Systems Work?

Battery storage systems are much more advanced than the traditional batteries that you purchase in a shop for your remote controls or children’s toys. These battery systems have the ability to be charged by renewable energy sources like wind power.

The best energy storage systems use algorithms to coordinate the use of the generated renewable energy throughout the system and computerised controls will be used to store the energy and decide the best points in which to release it and when to stop.

Energy is typically released at peak times for the national grid meaning that the demand for electricity will be reduced, therefore reducing the cost of your electricity bill each month.
