Effective storage systems are essential to the success of the energy transition.
This is because renewable energy sources, such as wind and solar, are naturally intermittent: the Sun doesn’t always shine, and the wind doesn’t always blow. These characteristics were traditionally seen as a weakness when making the case for renewable energy, but now, thanks to efficient storage systems, this problem has a solution.
We are witnessing the dawning of a new era for renewable energy, which is essential to the well-being of our planet and its inhabitants. On these pages we explain everything you need to know about energy storage and its vital role in the production of green energy.
You can find more information on our web, so please take a look.
Energy storage is defined as the capture of intermittently produced energy for future use.
In this way it can be made available for use 24 hours a day, and not just, for example, when the Sun is shining, and the wind is blowing. It can also protect users from potential interruptions that could threaten the energy supply.
As we explain later on, there are numerous types of energy storage, but the main one is battery storage. As is the case with electric vehicles, mobile phones and torches, batteries store the energy and make it available on demand, but on a larger scale. And the development projections for storage are promising.
According to a IRENA (the International Renewable Energy Agency) Report, Electricity Storage and Renewables, the potential doubling of the growth of renewables – between and – will require a tripling of the stock of electrical energy available in storage systems: from 4.67 terawatt hours in to a range between 11.89 and 15.72 TWh in .
Storage systems are fundamental to the future of renewable energy. They store electricity and make it available when there is greater need, acting as a balance between supply and demand and thus helping to stabilize the grid.
Year after year, new materials and cutting-edge technological solutions are being introduced, providing greater efficiency, lower costs and a design-to-recycle approach, in order to obtain a more sustainable product.
The benefits of energy storage are, like renewable energy itself, unlimited: lower costs, zero CO2 emissions, with untold benefits for both the environment and humanity. And, as is the case with renewable energy, BESS can create jobs. According to an article that was published on LinkedIn in October “The growth of the BESS industry has led to the development of new employment opportunities in manufacturing, installation, and maintenance.”
BESS is a “win-win situation” in every respect.
The energy storage market in the United States is growing rapidly. According to Statista it surpassed $1.6 billion in and is expected to reach $8.2 billion in . The sector was given a boost by the Inflation Reduction Act (IRA).
In March , Carla French, the principal director at the Department of Energy’s Office of Policy, addressed the Energy Summit USA in Austin, Texas. She told the audience: “Before IRA, our national labs were projecting about 50GW of energy storage buildout by . Post-IRA, our analysis, and pretty much everyone else’s, is now projecting more than 200GW by .”
Residential energy storage is becoming more popular in the United Kingdom as homeowners recognise the myriad benefits associated with storing energy at home.
There are actually several ways to source and then store renewable energy in a residential setting, but the easiest and most efficient method is via a battery energy storage system (BESS).
At AceOn, we have partnered with numerous housing associations, builders, and local governments in the UK to pioneer residential energy storage projects en masse.
Though we don’t supply BESS to individual homeowners, you can use this page as a helpful guide if you’re keen to learn more about residential energy storage for your home.
Also, if you are a home builder looking to partner with a renewable energy firm to roll out a large-scale home energy storage project, AceOn is the perfect partner for you.
Keep reading to learn more about residential energy storage, how it works, and what the benefits of home energy storage are.
Residential energy storage is a way of generating and storing renewable energy at home. There are several methods available for anyone interested in home energy storage, but the most efficient method is via solar and a battery energy storage system.
The solar panels receive UV rays, which are converted into electricity. Then, the battery energy storage system stores the energy for later use, meaning that a homeowner can tap into solar energy even when the sun isn’t shining.
While battery storage is the best option, some homeowners also opt for heat or thermal storage, but these options tend to be less efficient and more costly. At AceOn, we specialise in residential energy storage via BESS, and we explain how this works below.

There are several components to a home energy storage system. First and foremost, the system must be able to generate energy from a renewable source. Most homeowners opt for solar photovoltaic panels, but you can also generate power from wind turbines or even a hydroelectricity system.
The solar system is able to generate electricity during the day, and thanks to an inverter, this energy can power your electrical devices – everything ranging from the TV to the kettle in your home.
However, the issue for homeowners is what happens when solar panels or wind turbines are not able to generate power. In other words, what happens at night or when the wind isn’t blowing, respectively?
The answer is a battery energy storage system. At the residential level, homeowners can link a solar system to several lithium-ion batteries, which store any surplus energy generated during the day. This energy can then be used throughout the night when the panels are no longer able to generate electricity.
The use of a battery energy storage system makes home energy storage much more efficient, offering homeowners significant long-term cost savings, and it also reduces the homeowner’s reliance on the National Grid for power.
The benefits of residential energy storage are numerous. While some homeowners are put off by the initial cost of installation, we have found that home builders and housing associations in the UK are keen to add BESS to new and existing homes to help reduce the cost of living and to contribute to the UK government’s net-zero targets. Here are some of the benefits of home energy storage that are hard to ignore:
The main benefit of home energy storage is the fact that it can save you money. Figures from the Energy Saving Trust indicate that, although it’s not cheap to install, the long-term savings of BESS at home can be worth it. What’s more, the cost of living in the UK is sky-high right now, further adding to the appeal of turning to renewable energy at home for many.
The UK government is trying to phase out fossil fuels by via the Net Zero program. As such, we all have a responsibility to contribute to this ambitious target in any way that we can. Opting for a BESS at home is a great way to reduce your dependency on the National Grid, thus reducing your carbon footprint.
More broadly, residential energy storage offers Grid independence. Projections suggest that due to geopolitical instability and climate change, blackouts and power outages will become more common. If you’re able to generate your own energy at home, you don’t need to rely on the Grid and won’t be affected by power outages.
There’s no question that residential energy storage has a crucial role to play in the future of the United Kingdom. At AceOn, we have already seen first-hand the exceptional benefits that BESS has at the household level, thanks to several successful projects with housing associations and local governments.

You can store energy at home via a battery energy storage system (BESS). You can connect the BESS to a renewable source of energy like solar PV to generate and store renewable energy for when you need it most.
This depends on a number of factors. However, high-grade lithium-ion batteries for BESS tend to have a storage life of between 5-15 years. Before buying a residential battery, make sure you check for a manufacturer’s guarantee and always ask about the battery’s lifespan.
Yes, you can have battery storage without solar. Wind turbines are a viable alternative, as are hydroelectric systems. That being said, solar is the best option for a residential BESS.
Yes, provided that the solar system is professionally installed and that you buy high-quality lithium-ion batteries, home energy storage is safe. Don’t try and cut costs and corners by opting for cheap batteries or installation as it can cost you in the long run.
Most homeowners see long-term cost savings with residential energy storage. However, you will need to put together a budget before investing in a system and work out for yourself whether you will save money based on your current electricity consumption and the cost of energy in your area.
