Battery energy storage system (BESS) is an advanced technological solution that allows the storage of energy in multiple ways for later use. Lithium ion battery storage systems, in particular, use rechargeable batteries to store energy generated by solar panels or supplied by the grid and then make it available when required. Battery energy storage benefits include energy efficiency, savings, and sustainability by enabling renewable sources and lowering consumption. As the energy transition away from fossil fuels towards renewable energy gathers speed, battery storage systems are becoming a more common feature of everyday life. Given the fluctuations involved in energy sources like wind and solar, battery systems are vital for utilities, businesses and homes to achieve a continual power supply. Energy storage systems are no longer an afterthought or an add-on. They are an integral part of renewable energy solutions.
The operating principle of a battery energy storage system is straightforward. Batteries receive electricity from the power grid, straight from the power station, or from a renewable energy source like solar panels, and subsequently store it as current to then release it when it is needed. In a solar power system, the batteries charge during the day and discharge it when the sun is not shining. Modern batteries for a home or business solar energy system usually include a built-in inverter to change the DC current generated by solar panels into the AC current needed to power appliances or equipment. Battery storage works with an energy management system that manages the charge and discharge cycles based on real-time needs and availability.
Battery storage can be used in many ways that go beyond the simple emergency backup in the event of an energy shortage or blackout. Applications differ depending on whether the storage is being used for a business or a home.
For commercial and industrial users, there are several applications:
And battery storage allows businesses to participate in a Demand Response program, thereby creating potential new revenue streams.
Another important battery storage benefit is that it helps businesses avoid the costly disruptions caused by blackouts of the grid. Energy storage is a strategic benefit in times of rising energy costs and geopolitical issues that could affect the security of energy supply.
Most energy battery storage systems last between 5 to 15 years. As part of the ecosystem of solutions for the energy transition, battery energy storages are tools to enable sustainability and, at the same time, they themselves must be fully sustainable.
The reuse of batteries and recycling of the materials they contain at the end of their life are all-around sustainability goals and an effective application of the Circular Economy. Recovering an increasing quantity of materials from a lithium battery in a second life leads to environmental benefits, in both the extraction and disposal stages. Giving a second life to batteries, by reusing them in different but still effective ways, also leads to economic benefits.
