The approach could be useful in locations such as airfields, where there are higher-than-normal concentrations of CO2 emissions present. The concept design is looking into units that would look like rows and rows of big fans ‘that bring the air into boxes containing our batteries,’ the team says. Verdox is also developing systems that can efficiently pull carbon dioxide out of ambient air. This radically different approach allows for far more efficient capture and release of CO₂ using only electricity, and the need for heat or water,’ the team writes.Ĭaptured carbon dioxide to be released in caverns ‘Instead of squeezing out the CO₂ with heat, we also only apply a specific voltage to the capture material to release the CO₂. The design of our capture devices allows for gases to flow through with less resistance, making the soaking process more efficient. With their electric carbon removal, the Verdox team makes it easier to both soak up the carbon dioxide and squeeze it back out. This process uses vast amounts of energy and is therefore difficult to scale,’ the team writes. ‘The CO₂ is then squeezed out in the release process by applying large amounts of heat. Verdox compares traditional carbon capture systems to sponges since when carbon dioxide comes in contact with the capture material, it is soaked up and trapped inside the structure. Verdox makes it easier to release trapped carbon dioxide The team is now planning to commercialize their device to help ease climate change. When the battery becomes saturated, the carbon dioxide can be released as gas. When a low-level electric current flows in the device, the battery charges and the carbon dioxide that goes inside rises to the surface. The invention is kind of a battery that naturally attracts carbon dioxide under certain conditions and does not do anything when these conditions are not triggered. Alan Hatton – uses electrochemistry to capture carbon almost effortlessly. While most carbon removal devices capture carbon from an exhaust flow or air itself, which requires a lot of energy, Verdox – led by the MIT team Sahag Voskian and T. MIT researchers capture and remove carbon dioxide from the air using Verdox, an electricity-based device that helps clean carbon emissions. Electrically removing captured carbon dioxide with verdox
