Energy storage systems are a critical source of backup power, harnessing energy needed in situations such as peak demand and black-outs. 

These systems store excess energy generated by sources like solar and wind and release it when it’s needed most, providing resilience and reliability to the power grid.

Lithium-ion batteries, in particular, have become a leading technology in this field due to their efficiency, durability, and versatility.

Below are a few key reasons battery storage systems are needed:

7 Reasons We Need Energy Storage Systems

Stabilising the Electrical Grid 

The electrical grid is a complex infrastructure that supplies power to millions of people and industries. However, the grid faces challenges such as fluctuating demand, infrastructure limitations, and reliance on fossil fuels. 

By incorporating battery energy storage, especially lithium-ion batteries, the grid gains a buffer. This storage helps balance supply and demand, especially during peak demand times when energy needs spike, and transmission and distribution systems are stressed. Storing energy allows for quick release during high-demand periods, reducing the risk of blackouts and supporting grid reliability.

Supporting Renewable Energy Integration 

As renewable energy sources like solar and wind become more prominent, managing their intermittent nature becomes crucial. 

These energy sources are dependent on weather conditions, leading to periods of surplus generation (sunny or windy days) and low generation (cloudy or calm days). 

Battery energy storage systems make it possible to store excess energy generated during peak renewable production and discharge it when production drops, ensuring a consistent power supply. 

Reducing Dependence on Fossil Fuels 

Traditional power generation heavily relies on fossil fuels, which contribute to greenhouse gas emissions and other environmental pollutants. By investing in lithium-ion batteries and other storage technologies, we can reduce the need for fossil-fuel-based power plants, especially during peak demand. 

This shift lowers electricity costs by reducing the operational costs associated with fossil-fuel plants and decreasing the environmental impact. ESS contributes to the decarbonisation of the grid, helping countries meet their climate goals and lowering the overall carbon footprint of electricity generation.

Supporting Electric Vehicles (EVs) 

EVs are a critical part of the clean energy transition, and they rely on battery technology, often lithium-ion, for power. As EV adoption grows, so does the demand for efficient and high-capacity batteries. 

Additionally, ESS technology complements EV infrastructure by storing energy generated from renewable sources to charge EVs during off-peak times. This synergy between battery storage and EVs supports cleaner transportation, reduces emissions, and lessens the overall strain on the grid.

Enhancing Energy Efficiency and Lowering Electricity Costs 

Efficient energy storage systems contribute significantly to energy efficiency by reducing the amount of wasted energy. By capturing surplus energy that would otherwise go unused, ESS ensures that power is available when it’s needed without requiring additional generation. 

This capability not only enhances grid efficiency but also reduces electricity costs for consumers, as stored energy can be released during peak times when electricity prices are higher. Over time, this efficiency contributes to lower utility bills and promotes more responsible energy use.

Resilience and Backup Power in Emergencies 

Energy storage systems offer vital backup power during unexpected outages, such as those caused by natural disasters or sudden demand surges. In these situations, stored energy can be rapidly deployed to ensure that essential services and households remain powered. 

Lithium-ion battery storage is particularly effective for these applications because of its fast response times and high energy density. By providing a reliable source of backup power, ESS enhances community resilience and mitigates the impact of power outages.

Encouraging Technological Advancements in Storage Solutions 

The rise in demand for ESS has spurred rapid advancements in storage technologies. Lithium-ion batteries have become the industry standard for high-performance energy storage due to their high energy density, long cycle life, and efficiency. 

However, ongoing research and innovation are leading to new developments, including solid-state batteries and flow batteries. These advancements contribute to a more efficient and sustainable energy landscape, lowering costs and improving battery longevity, which in turn accelerates the transition to a cleaner energy system.

The global energy storage market almost tripled in 2023. Energy storage is a game-changer for sustainability. Why? Becuase it helps us make the most of renewable energy sources like solar and wind, which aren’t always available when we need them most. 

The sun doesn’t shine at night, and wind can be unpredictable, but energy storage systems allow us to store excess energy when it’s plentiful and use it later when demand is high.

By storing this energy, we can reduce our reliance on fossil fuels and stabilise electricity grids with a cleaner, more reliable power supply. It also helps balance energy loads, preventing waste during times of surplus and lowering overall energy costs by reducing the need for peak-time electricity from traditional sources.

Energy storage systems also support a more resilient grid, providing backup power during outages or emergencies, making sure that even if the grid fails, there’s a stored energy supply ready to step in. This is particularly crucial for critical infrastructure like hospitals, data centres, and emergency services.

4 Reasons Energy Storage Benefits Sustainability

Maximises Renewable Energy Use

Energy storage allows us to capture and store excess power generated from solar and wind sources, making clean energy available on back-up.

Reduces Fossil Fuel Reliance

By storing renewable energy, we can reduce the need for backup power from fossil fuels, lowering carbon emissions and promoting a cleaner power supply.

Stabilises Electricity Grid

Energy storage helps smooth out fluctuations in supply and demand, ensuring consistent power availability. This reduces strain on the grid and prevents wasteful energy spikes.

Supports Energy Reliance

During power outages or emergencies, energy storage systems can step in to provide backup power, making communities more self-reliant and less vulnerable to disruptions in traditional energy supplies.

Materials Can Be Recycled

When it comes to energy storage, the concern about battery waste is real, but there’s good news: batteries can be recycled! Specifically, lithium-ion batteries, which are commonly used in energy storage systems, can be broken down and valuable materials like lithium, cobalt, and nickel can be recovered. This helps minimise waste, reduce the need for new resource extraction, and cut down on the environmental impact of mining.

Recycling batteries also ensures that hazardous materials don’t end up in landfills, which protects ecosystems from potential contamination. Companies like ours provide specialised recycling services to responsibly dispose of these batteries and give them a second life. 

So while batteries do have a limited lifespan, their materials don’t have to go to waste—they can be reused in new energy storage systems, helping create a more sustainable cycle.

Battery energy storage systems (BESS) work by storing energy to be released for later use. These energy storage systems often use lithium-ion batteries to store the energy and release it when required. 

They’re the go-to solution for storing energy from renewable sources like solar and wind because they’re efficient, reliable, and capable of storing large amounts of stored electricity.

The electricity gets stored in these giant, rechargeable batteries and is released to power homes, businesses, or even entire electricity grids when demand spikes or during a power outage. New battery energy storage system (BESS) installations worldwide added up to 74 gigawatt-hours in 2023, up from 27 gigawatt-hours a year earlier.

What Are Battery Energy Storage Systems Used For?

Security Monitoring

Battery energy storage systems (BESS) are used to support critical monitoring systems like security systems, smoke detectors, and even medical equipment. These systems require a reliable, uninterrupted power supply to function effectively, and that’s where battery storage comes in. 

For security systems, BESS ensures that surveillance cameras, alarms, and monitoring devices continue to operate even during a power outage. Since security systems are crucial for protecting businesses, having a backup power supply in the form of a battery is essential to avoid any downtime.

Medical Equipment

For medical equipment, especially in hospitals or for at-home patient care, reliable power is critical. BESS can store energy supplies and kick in during emergencies, providing a dependable energy source until regular power is restored.

Solar Energy

Imagine a sunny day when your solar panels are producing more energy than your house can use. Instead of letting that energy go to waste, a BESS allows you to store energy for use later—like when the sun goes down or clouds roll in. It’s the ultimate energy storage solution for ensuring you have a consistent power supply, even when your renewable energy sources aren’t producing at full capacity.

Electricity

On a large scale, BESS are used by utility companies to keep the grid running smoothly. When there’s too much energy being produced, say, during high winds or sunny days, the excess energy gets stored in these systems. Then, during peak hours when energy demand shoots up, the battery storage system releases its stored electricity back into the grid. This process not only prevents waste but also helps lower overall energy costs by providing electricity when it’s needed most. In emergency situations like a power outage, BESS can be lifesavers by ensuring backup energy supplies are available to keep everything running.

Why Are Lithium-Ion Batteries Used For Energy Storage Systems?

So, why do we love lithium-ion batteries for energy storage? Well, for starters, they have a high energy density, meaning they can pack a lot of power into a relatively small space. This makes them perfect for both residential and large scale battery storage applications. Another major plus is that they’re incredibly efficient at cycling energy—charging and discharging—without losing much of their capacity. That means they can store electricity and release it over and over again, making them a reliable choice for both short-term and long-term energy storage.

Lithium-ion batteries are also pretty versatile, able to handle both the short bursts of energy needed to smooth out fluctuations in electricity grids, as well as the longer, sustained output. 

Since they’re commonly used in everything from solar and wind energy systems to electric vehicles, their production has scaled up, making them more affordable.

Can You Recycle These Batteries?

Absolutely! And this is where we come in. While lithium-ion batteries are fantastic for storing energy, they do eventually reach the end of their lifecycle. But instead of ending up in a landfill, these batteries can—and should—be recycled. 

By recycling lithium-ion batteries used in energy storage systems, valuable materials like lithium, cobalt, and nickel can be recovered and reused to make new batteries. This not only reduces the environmental impact of mining for new resources but also keeps hazardous materials out of our ecosystems.

At Lithium Cycle, we specialise in recycling batteries from energy storage systems, ensuring that the life of your energy storage solution doesn’t end when the battery does. 

Modern hybrid cars use lithium-ion batteries and nickel-metal-hydride (NiMH) batteries. 

The type of battery used in a hybrid car really depends on the make and model. For instance, if you’re driving a plug-in hybrid like the Toyota Prius Prime or Chevrolet Volt, chances are you’re benefiting from a large li-ion battery pack under the hood. Why? Li-ion batteries have a higher energy density compared to NiMH batteries, which means they can store more electrical energy in a smaller, lighter package. 

This allows plug-in hybrids to go further on electric power before the gasoline engine has to kick in to recharge the battery or help drive the car.

On the other hand, some hybrids, especially older models, rely on NiMH batteries. These batteries may not be as energy-dense, but they’re tough, reliable, and get the job done when it comes to powering the electric motor. They’ve been around longer, and for many hybrid cars, they’re still a solid choice.

Why Do Hybrid Cars Use These Battery Types?

Hybrid cars are all about efficiency, and these battery types—whether lithium-ion or nickel-metal-hydride—help maximise fuel economy. By storing and releasing electrical energy when needed, hybrid batteries allow the car to seamlessly switch between gasoline and electric power. This reduces fuel consumption and makes hybrids incredibly fuel efficient.

A key reason hybrids use these specific battery types is because of regenerative braking. When you brake, the car captures that wasted energy and uses it to recharge the battery, boosting your efficiency even more. It’s like magic—except it’s all science! High-voltage batteries are essential for this process, as they can store the electrical energy needed to keep things running without relying solely on gasoline.

In addition to improving efficiency, both li-ion and NiMH batteries are durable enough to handle the frequent charging and discharging cycles that come with hybrid driving. This means that while the battery may seem to be working hard in the background, it’s built to last.

How Do I Dispose Of Hybrid Vehicle Batteries?

One thing that often gets overlooked is what happens when these batteries reach the end of their life. And yes, they do eventually run out of juice—though they last longer than many people think. So, how long do hybrid batteries last? Well, it can vary depending on the make, model, and how the vehicle is driven, but many hybrid batteries are built to last anywhere from 8 to 15 years.

When the time comes to replace that trusty hybrid battery, don’t just throw it in your general rubbish. Hybrid batteries are recyclable, and that’s where we come in. If you’ve got an old li-ion from your hybrid or electric vehicle, we can collect and recycle it responsibly. 

By recycling, you’re helping ensure that valuable materials are recovered and reused, and you’re keeping toxic chemicals out of landfills. Plus, it means fewer resources are needed to produce new batteries, making the entire process a little bit greener.

Remember, these batteries are high-voltage powerhouses, so handling and disposing of them properly is crucial. Always recycle through certified programs to make sure you’re doing your part in maintaining a sustainable cycle of battery production and disposal.
