All you need to know about energy storage

What are energy storage batteries?

Energy storage batteries are rechargeable lithium batteries that are used for energy storage. One of the current, leading companies in battery storage is Tesla who make rechargeable batteries for the home and for electric cars. They offer two main types of battery storage – Powerwall and Powerpack. The Powerwall model is commonly used for home energy storage, it works with solar panels, can be used for back-up power and also for off-the-grid living. The Powerpack model is used more commonly used for commercial use or to help electric utility companies who are involved in supplying our national electricity supply.

Using Tesla batteries as an example, here's how long home storage batteries last and what they cost:

  • Tesla battery life - A Tesla Powerwall battery will power your home indefinitely when it's working with solar panels.

  • Tesla battery cost - For a home Powerwall 2 battery, the cost is circa £5,400 (1). For more costs and estimates, have a read of this article from alphr.com.

How could battery storage affect our electricity supply?

Storage batteries store and distribute renewable energy. They have the ability to change the way we power the future because they can provide large-scale renewable power to homes, businesses and ultimately, can add to any grid system in the world. The Tesla batteries that are already being used in large storage facilities around the world feed into the electricity supply in those areas, reducing the amount that those areas need to rely on the grid. Battery storage systems are increasing in numbers and companies are offering them on larger and larger scale. An increase in these battery storage systems means a reduction in the need for traditional power sources.

We are consuming less and less non-renewable energy in the UK, moving towards more renewable sources – which is great news. GOV.UK published this helpful article on how national energy consumption is changing.

What's the future of energy storage?

More and more people want to live sustainably and protect the environment for future generations. Moving away from using non-renewable sources of energy comes with this change. According to McKinsey research, battery storage is becoming a cheaper option, which makes it not only a sustainable energy source but an accessable option for home energy storage too. The EDF Group are investing in battery storage - $10 billion by 2035 - to help support a more sustainable energy future. It's important to this as an energy company so we can make sure our electricity systems can support new technology and renewable sources of energy.

Electric vehicles are also rising in popularity for the same reason - people don't want to contribute to environmental problems and are looking for other options. Electric vehicles are strongly linked to battery storage because instead of using fuel for your electric car, you charge it with a battery at home or out and about. If you have a storage system in your home, it meamns you can get the best charging option for your car.
