New battery technology is revolutionizing the use of renewable energy and carbon capture.
A promising innovation in the field of renewable energy is emerging and could play a crucial role in the fight against climate change. Researchers at Oak Ridge National Laboratory in the United States have developed new battery technology that not only stores renewable energy efficiently, but also captures carbon dioxide (CO₂) from the air. This two-pronged approach promises to transform the way we manage energy and combat carbon pollution.
Battery revolutionizes energy storage
New battery technology is designed to store energy generated by renewable sources such as solar panels and wind turbines.
One of the major limitations of these energy sources is their intermittency: energy is only generated when there is sunlight or wind, making the development of effective storage methods crucial.
- New technology converts carbon dioxide into methane fuel
- China plans to collect solar energy in space and send it back to Earth
- Green hydrogen gains momentum in São Paulo: State invests R$32 million in innovative center to lead the fight against emissions and boost clean energy
- Petrobras invests heavily in Brazil's sustainable future, with US$4,3 billion for solar and wind energy, part of an ambitious US$111 billion plan by 2029!

New batteries solve this problem by storing energy for later use, ensuring a continuous source of electricity, even when environmental conditions are not favorable.
CO₂ capture and conversion
In addition to storing energy, these batteries have the innovative ability to capture CO₂ from ambient air and convert it into useful products.
During the energy storage process, batteries absorb carbon dioxide from industrial emissions and transform it into a solid form.
This solid, which can be used in various industrial processes, is produced through an electrochemical reaction between CO₂ and the battery components.
Two promising battery prototypes
Researchers have developed two different types of batteries for this purpose: the Na-CO₂ battery and the Al-CO₂ battery.
The Na-CO₂ battery uses sodium from seawater and an iron-nickel catalyst to convert CO₂ into solid carbon.
The Al-CO₂ battery uses aluminum for the same purpose.
Both batteries proved effective in capturing CO₂, but the Al-CO₂ battery stood out for its ability to store up to 10 hours of electricity and maintain this capacity for 600 hours of continuous use, a significant improvement over previous prototypes.
Industrial and environmental benefits
The process of operating these batteries results in the formation of carbonate, which can be dissolved in the liquid electrolyte to continually improve battery performance, or filtered and used in other industrial sectors.
These byproducts are used in various industries, from pharmaceuticals to cement, expanding the potential use of this technology beyond simple energy storage.
Furthermore, the only gases released during the process are oxygen and hydrogen. These gases do not contribute to global warming and can be captured to generate more energy or fuels, further increasing the system's efficiency.
The future of renewable energy with new technologies
With this new technology, the combination of energy storage and carbon capture offers an innovative solution to two of today's biggest environmental challenges: the need for sustainable energy sources and the reduction of CO₂ emissions.
The ability of these batteries to transform carbon dioxide into useful products while storing renewable energy could accelerate the transition to a low-carbon economy.
Continued research and development is essential to refine this technology and make it commercially viable.
However, the advances already made by researchers at Oak Ridge National Laboratory are promising and point to a future where batteries not only store energy, but also help clean the air we breathe.
Battery innovation is at the heart of an energy revolution.
With the ability to capture and convert CO₂, as well as store renewable energy, these new batteries could play a vital role in mitigating climate change.
The technology developed by Oak Ridge National Laboratory represents a significant step toward a more sustainable future.
As we continue to address global environmental challenges, solutions like these will be crucial to creating a cleaner, more sustainable world.
