MIT researchers develop new carbon capture method using seawater

Scientists at MIT have developed a promising new method for capturing and storing carbon emissions using seawater. The approach involves passing air through a mixture of seawater and a compound called tetraalkylammonium hydroxide, which selectively captures carbon dioxide (CO2) from the air.

The captured CO2 can then be converted into a solid carbonate material, which can be easily stored for long periods of time or used in the production of other materials. This process not only helps reduce the amount of CO2 in the atmosphere, but also has the potential to produce valuable materials in the process.

The new method could have a significant impact on the fight against climate change, as current carbon capture technologies are expensive and energy-intensive. Additionally, the use of seawater is a sustainable alternative to other methods that rely on freshwater sources.

The researchers have successfully tested the method in the lab and are now working to scale it up for real-world applications. While there is still work to be done, this breakthrough is an important step towards a more sustainable future.

The study, which was published in the journal Energy & Environmental Science, highlights the potential of seawater-based carbon capture as a viable option for reducing greenhouse gas emissions. As our planet continues to face the impacts of climate change, it is more important than ever to explore innovative solutions like this one.
