The South African power grid is at risk, and Eskom, the country’s electricity utility, is unable to meet current demand. As a result, load shedding, or deliberate power outages, have become increasingly common. As of midway through May, 2023 has already become the worst year ever.
There are two main places for storing energy: the transmission and distribution networks, and the end user’s home. Energy storage allows for the decoupling of electricity generation and supply schedules, which has numerous benefits for various parties.
Utility-scale battery deployment has recently seen exponential growth, marking a significant change in the worldwide energy storage industry. Lithium-ion battery prices have dropped by almost 80% since 2013. This has contributed to the industry’s rapid expansion. One key advantage of electric storage batteries over other grid storage methods is how rapidly they can be put into service. Alternatively, you can use a solar energy system.
What are Electricity Storage Batteries?
Battery storage is a technology that allows utilities and power companies, as well as private owners to store energy for later use. A battery energy storage system (BESS) is an electrochemical device that receives energy from the grid or a power plant, stores it until it is needed, and then discharges it to deliver electricity or other grid services. Lithium-ion, lead-acid, redox flow, and molten salt batteries, including sodium-based chemistries, are only some of the battery types now available or being researched for grid-scale applications. When it comes to technical specifications, different battery chemistries offer varying degrees of performance, as well as their own set of benefits and drawbacks.
These days, most battery energy storage systems come pre-wired with an inverter and run on computerised control systems. They are effortless to set up, need little in the way of upkeep, and can be operated by anyone without any special training. They can withstand any kind of weather and are completely harmless to both humans and animals.
Algorithms in the intelligent battery software regulate power output, and digital control systems determine whether or not to release power to the grid at a given time. In order to keep prices down and electricity flowing, the battery storage system releases energy during periods of peak demand.
The Batteries You Can Choose From
There is no single battery type that is universally used in energy storage devices. New types of batteries are constantly being brought to the market, expanding the already wide variety of batteries utilised in battery storage systems.
Battery energy storage systems typically employ the following battery types:
Lithium-ion (Li-ion) batteries
Zinc-bromine flow batteries
Redox flow batteries
Lithium-ion batteries are widely employed in energy storage devices. In reality, 90% of the worldwide market for grid battery storage is made up of lithium-ion batteries. In all likelihood, you have some experience with lithium-ion batteries. Electronic devices like smartphones and laptops rely on lithium-ion batteries. Though it may be more expensive than other options, lithium-ion batteries are the lightest and most compact of the bunch.
Lead-acid batteries have been used for decades in energy storage devices and are the most popular type of rechargeable battery. You may be familiar with lead-acid batteries because they are the most common type of car battery. They are the cheapest alternative, but have the shortest lifespan. Lead-acid batteries are the most recyclable type of battery due to their long history of recycling.
Liquid electrolyte solutions stored in a redox flow battery undergo chemical and oxidation reactions as they move through the battery’s electrochemical cells during the charging and discharging processes. In a redox flow battery, the electrolytes are pumped from a reservoir tank rather than being contained within the secondary battery, as is the case with conventional batteries. The process of discharging a battery involves the release of an electron from the negative terminal and its subsequent acceptance by the positive terminal through a reduction reaction.
Maintenance of Your Electric Batteries Matters
Taking appropriate care of your electric storage batteries will ensure that they last as long as possible and provide you with the maximum amount of service. Consistent focus on a handful of best practises can vastly increase the longevity and efficiency. First and foremost, maintain a working environment that is free of obstacles by protecting batteries and keeping them at the right temperature.
Check your equipment on a regular basis for signs of damage, wear, and corrosion, and address any issues you detect immediately to keep it running smoothly for longer. Regular charging and discharging cycles should be established to prevent overcharging and deep draining, which can be harmful to batteries. For optimal management and functionality, always use the most recent version of any software used to administer your battery system. If you follow these guidelines, your energy storage system will last for many years and protect your investment.
