Discover the new batteries that could revolutionize the solar energy market in Brazil and around the world.
You won't believe the next big solar energy revolution! New batteries are about to change everything we know about energy storage and can be the solution to the challenges the market faces.
The solar energy in Brazil is facing a major challenge. Energy distributors are aggressively limiting the connection of new photovoltaic systems on your network. This barrier is causing frustration and delays, making the expansion of the solar energy in some cases. But there is a solution that can completely turn the game around!
Innovative battery technologies are poised to revolutionize energy storage and overcome these limitations. Companies around the world are investing heavily in new batteries which promise to be cheaper, more efficient and less harmful to the environment.

Sodium Ion Batteries: Salt as a protagonist in solar energy
What if it were possible to replace rare materials with something as common as table salt? This is the proposal of sodium ion batteries, the first promising technology on our list for solar energy. Sodium is 1.400 times more abundant in the Earth's crust than lithium, presenting itself as a viable and economical alternative.
These batteries operate in a similar way to conventional lithium-ion batteries, but with a cathode made of sodium. Although they have a lower energy density, which results in physically larger batteries, they are ideal for large-scale energy storage in the residential, commercial and industrial sectors.
Sand Thermal Batteries: heat stored for months
Another surprising innovation is the sand thermal batteries. A Finnish company has developed the world's first sand battery, capable of storing energy in the form of heat. Using sand, which is abundant and cheap, the system takes advantage of its ability to be heated to 1.000°C to store thermal energy for months.
The battery consists of an insulated steel silo, filled with sand and equipped with heat transfer tubes. The stored heat can be used to heat buildings, urban networks and even in industrial processes., maintaining a thermal efficiency of up to 95%, in addition to solar energy. This battery can last up to 50 years without significant degradation.
Gravity Batteries: the force of nature in our favor
To close with a flourish, we have the gravity batteries, a simple and revolutionary way to store energy. When there is excess energy, such as during peak energy production, solar energy or wind, this energy is used to lift heavy weights to a certain height. Potential energy is stored and, when needed, the weights are released, activating a generator that converts the energy into electricity.
This technology has a virtually indefinite lifespan., requiring only regular maintenance. Companies are already developing real projects, such as a 122-meter-high tower that uses cranes to lift and stack 35-ton bricks. With much lower operating costs and efficiency comparable to lithium batteries, they present themselves as an attractive solution for the future of renewable energies.
The promising future of solar energy
All these new batteries are a sign that we are on the verge of a major revolution in the solar energy. Although lithium still has its applications, viable alternatives are emerging for energy storage, whether stationary, in electric vehicles or other applications.
And you, which of these new batteries surprised you the most? Do you believe they can revolutionize the solar energy market in Brazil? Leave your opinion in the comments!
