If you live on this planet and you’re not spending your whole day playing video games, you might have heard about being too much carbon dioxide (CO2) in the Earth’s atmosphere. And this is pretty bad for our environment since that’s why we have such peculiar climate changes.
Carbon dioxide is being created by cars, factories, and even us human beings with literally every breath. We are inhaling oxygen produced by plants and exhaling carbon dioxide instead. But engineers from the Massachusetts Institute of Technology may have found a great solution which doesn’t require the investment of significant amounts of money.
Works on almost any concentration level
The new system has a device at its heart which behaves most likely as a battery. It will absorb carbon dioxide from a gas stream that passes over its electrodes.
MIT News informs us that the future invention will be able to perform at any concentration level, from power plants to open air. In a world where anything costs money, another good news is reaching us: the new system requires less money and energy to be able to operate, unlike other methods proposed by scientists over time.
“In my laboratories, we have been striving to develop new technologies to tackle a range of environmental issues that avoid the need for thermal energy sources, changes in system pressure or addition of chemicals to complete the separation and release cycles,” Hatton told MIT News.
“This carbon dioxide capture technology is a clear demonstration of the power of electrochemical approaches that require only small swings in voltage to drive the separations.”
MIT postdoc Sahag Voskian and professor T. Alan Hatton are detailing us how the new invention will be working in the journal Energy and Environmental Science, in a paper called Faradaic Electro-swing Reactive Adsorption for CO2 Capture.
