A new method of capturing CO2 from the air was developed at the University of Cincinnati

Until now, carbon capture and sequestration efforts have focused primarily on efforts to remove greenhouse gases from emissions from power plants and industries.

Details

Chemical engineers have developed an effective method of extracting carbon directly from the atmosphere. The University of Cincinnati has developed a system for removing carbon dioxide from the air with a concentration of about 420 parts per million. It is indicated that the process, although not simple, is promising and can be deployed almost anywhere.

For reference

University of Cincinnati professor Ju-Yup Lee explains that the “golden fleece” of carbon capture is the extraction of carbon dioxide directly from the atmosphere. It is quite difficult. Until now, carbon capture has mostly focused on removing greenhouse gases at their source, such as emissions from power plants, oil refineries, concrete plants and other industries.

The concentration of carbon dioxide in the atmosphere is very low. It’s like trying to get a handful of red ping-pong balls out of a football stadium full of white balls.

Lee and his students have developed a promising air removal system that uses electricity to separate carbon dioxide. The system has been improved by using hot water instead of electricity or steam, making it more energy efficient than other carbon capture systems.

Thus, it is reliable enough to withstand thousands of cycles.

Lee’s team expanded the project at one of UC’s top engineering labs, where students work on engines and other large-scale industrial projects. There is a climate-controlled environmental chamber that allows for larger-scale experiments.

Researchers have built a human-sized canister that re-takes air from outside the building. Temperature, humidity and wind speed can be controlled indoors. At the same time, researchers use honeycomb blocks the size of a loaf of bread.

I think this is a great project. We are doing some real programs that can help the environment

Professor Lee claims that his technology has already been proven to “reduce the heat required for desorption by 50%”.

He is confident that such a system can play an important role in the fight against climate change, as the demand for electricity is expected to increase in the coming years.

We will remind

Global efforts to combat climate change could be dealt a major blow if US President Donald Trump pulls out of the Paris Agreement again.
