MIT Researchers Found a Much Easier and Inexpensive Solution to the Carbon Dioxide Problem

MIT engineers have developed a much cheaper and easier method for capturing carbon dioxide emitted from power chimneys. Thanks to the developed method, much less energy is consumed and costs are reduced compared to existing processes.

Capturing and removing direct carbon dioxide from the chimneys can be the only and most important way to prevent the devastating effects of climate change. At this point, MIT engineers who wanted to capture carbon dioxide developed a device that consumes much less energy and costs less than today’s technologies.

Published in the journal Energy and Environmental Science, the device is reminiscent of a battery and absorbs carbon dioxide passing over the electrodes in the air. The device can be made as big or small as necessary, so that it will be easier to use in different carbon dioxide emission sources.

The new method uses much less energy than existing technologies:

Unlike today’s carbon capture techniques, the device operates in a very wide concentration range. For this reason, it can even be used to clean carbon dioxide from the factory and plant chimneys, or to directly extract it from the lower atmosphere.

The present methods typically employ an aqueous solution of amines or solid sorbent materials to absorb carbon dioxide from the chimneys. In these methods, the solution needs to be heated to release carbon dioxide and reuse the amine, which consumes a lot of energy. In addition, the technology does not work at low concentrations of airborne concentrations. Companies like Climeworks have developed special filters to absorb carbon dioxide directly from the air, but they are inadequate.

This new system developed by MIT uses only electricity, so it can be said to work with renewable energy. The device contains two thin and flexible electrode plates coated with two different chemical compounds. During loading, one of the compounds called polyantraquinone reacts with carbon dioxide and combines the gas with the electrode. The discharging process releases carbon dioxide and releases the quinone (TUBA Term: the general term used for benzene-derived compounds that function in electron conduction processes in living things) for reuse.
