Carbon dioxide capture took a leap forward after a team of researcher started testing and using regular baking soda for the process. The team was comprised of researchers from Lawrence Livermore who partnered scientists from Harvard University and the University of Illinois at Urbana-Champaign
The group came up with another kind of carbon catch solution made out of core-shell microcapsules, which comprise a very porous polymer shell and a liquid (composed of sodium carbonate mix) that responds to and assimilates carbon dioxide (CO2). Sodium carbonate is normally known as the fundamental ingredient of baking soda. The capsules maintain the fluid contained inside the center, and permit the CO2 gas to move back and forth through the container shell.
Until now, microcapsules have been utilized for controlled conveyance and discharge (e.g., pharmaceuticals, food seasoning, beauty care products, farming, and so forth.) but this is the first trial using this procedure for controlled CO2 catch and discharge.
The goal of carbon capture is to avoid the release of extensive amounts of CO2 into the environment from fossil fuel use in different industrial ventures. CO2 is a greenhouse gas that traps high temperature and cause the planet to become hotter.
Nevertheless, presently used procedures, while effective, can be destructive to nature. The ability to switch from harsh liquids, like monoethanol amine to catch Co2, to more environmental friendly ones, such as carbonates, is a key quality of the group’s exploration.
However, currently used methods, while successful, can be harmful to the environment. The ability to move away from caustic fluids, such as monoethanol amine to capture CO2, to more environmentally benign ones, like carbonates, is a key aspect of the team’s research.
Roger Aines, one of the Lawrence Livermore researchers clarified :
“Our method is a huge improvement in terms of environmental impacts because we are able to use simple baking soda — present in every kitchen — as the active chemical. Corrosiveness also is improved because the chemical is more benign and always is encapsulated. Putting the carbonate solution inside of the capsules allows it to be used for CO2 capture without making direct contact with the surface of equipment in the power plant, as well as being able to move it between absorption and release towers easily, even when it absorbs so much CO2 that it solidifies.”
Not at all like more acid sorbents employed for capturing Co2, the microcapsules just respond to the gas in question, respectively CO2. This capturing via capsules likewise significantly expands absorption in contrast with customary carbon capture systems. According to Aines, the microcapsules force the baking soda to remain in small droplets and these ones have a faster reaction because they contact a greater amount of the Co2.
Aines also added this will entail another sort of capture procedure, which Livermore is taking a shot at with the National Energy Technology Laboratory (NETL). The encapsulation procedure was created as one of the Department of Energy’s inaugural Advanced Research Projects Agency-Energy (ARPA-E) innovative carbon catch ventures.
The new method can be adapted to work with coal or natural gas-powered plants and in industrial techniques like steel production.
