Home Energy Storage Bricks

When people hear the words “home energy storage,” they often think of massive batteries. But a new technology could make this idea a reality with bricks.

The system uses excess wind and solar energy to raise huge bricks into the air, where they store potential energy. The bricks are then lowered to generate electricity.


Home energy storage bricks offer a promising solution to the intermittency problem of renewable energy. They allow excess solar power to be stored for use later in the day or during grid outages. This can reduce reliance on fossil fuels and save money on energy bills. They can also be built into existing homes, reducing the need for expensive and intrusive construction.

While a lot of work remains to be done, the concept is a significant step forward for greener energy. It offers a potential alternative to conventional batteries and thermal storage systems like molten salts or flywheels. And it uses common materials, making it more affordable and scalable than other energy storage technologies.

The technology works by coating ordinary red bricks with Home energy storage bricks a thin film of plastic nanofiber known as PEDOT. This transforms the bricks from their natural color to a dark shade of blue. It also makes them conductive. The cations in the PEDOT molecule absorb and store electricity, much like a battery. But unlike a battery, a PEDOT supercapacitor can discharge this charge very quickly.

In fact, a small startup called Rondo Energy has already started production of this technology. They are building a 90 gigawatt hour per year factory, which is larger than any lithium-ion battery factory. This means that this brick-based technology could be used for everything from lighting to charging phones in the future.

Energy density

A key metric for battery performance is its energy density, which measures how much electricity it can store per unit of volume. The higher the energy density, the smaller and lighter it is, which improves its mobility and ease of use. A large battery can deliver more power to a load than a small one, but it also takes up more space and is more expensive to transport.

There are several companies working on innovative home energy storage solutions. Several of them have developed sand batteries that capitalize on the cost-effectiveness of sand and the high temperatures at which it can be stored to generate electricity. Others, like Rondo Energy, have opted for heat storage systems that leverage a stack of bricks infused with iron wire (similar to the ones in your toaster) that can be heated by wind or solar power. This enables faster charging and the system can run continuously, as opposed to having to stop periodically to cool down.

Julio D’Arcy, a chemist in the Source program at Washington University, has developed a proof-of-concept that uses simple red construction bricks to hold and release electricity. The bricks, which can be plugged in to a power source, take 13 minutes to charge and can be recharged over 10,000 times. These brick supercapacitors can be integrated into building structures, and the technology could help solve energy storage problems that are still being addressed by conventional technologies.


Energy storage bricks are a promising solution to the problem of powering renewable energy sources. They use a natural and abundant material, brick, which can be heated and cooled quickly to store energy. Unlike traditional batteries, they do not require water or rare elements like lithium and cobalt. They also do not degrade over time and can withstand Cat 4 hurricane winds and magnitude 8 earthquakes.

Researchers from Washington University in St. Louis used ordinary red construction bricks to create a prototype that holds electricity and powers small devices. Their proof-of-concept device produces 3W of electricity and can run over a wide range of temperatures. It can even keep a green LED light on for 10 minutes.

This technology could provide a valuable alternative to lithium-ion batteries, Customized lithium battery pack which are expensive and have negative environmental impacts. In addition, it does not need a grid or expensive infrastructure and is safe for the environment. The research team hopes to scale up the technology for commercial use.

To use energy-storing bricks, electricity from renewable sources is fed into electric motors that raise and reposition them. They are then accelerated or slowed through artificial intelligence computerized control to allow for faster or slower electricity discharge. One brick raised 100 meters in less than a minute stores about 10 MWh of electricity.


Home energy storage systems are a popular way to store excess solar power for later use. However, it is important to remember that battery safety and management are key concerns. By selecting high-quality batteries, designing safe and reliable systems, implementing monitoring and control systems, conducting regular maintenance, and promoting responsible use, it is possible to minimize the risks of thermal runaway and other safety hazards.

A new technology called brick supercapacitors holds potential as a building material that can be used to store energy. It uses a combination of red bricks and chemical processing to turn them into electrical devices that can hold electricity like a battery. The bricks can also be stacked to increase the capacity of the system. In this way, the technology could be an alternative to large-scale pumped hydro storage.

The bricks contain iron oxide, which is essential for triggering the polymerization reaction that generates the stored electricity. They are then covered with a coating of the electrically-conductive plastic PEDOT, which penetrates the brick’s pores and serves as an ion sponge that stores and conducts electricity. This system does not degrade over time, does not require water or rare elements like lithium, and can withstand Cat 4 hurricane winds and magnitude 8 earthquakes. It is also much cheaper than lithium-ion batteries and can store ten times more energy per unit of volume.
