Samsung patents carbon capture liquid using enzyme-boosted solution

Samsung describes a liquid mixture designed to pull carbon dioxide out of the air or industrial exhaust. The solution uses potassium carbonate mixed with a specific enzyme called carbonic anhydrase, which is held in tiny porous structures to work more effectively.

Why it mattersThis filing focuses on improving the efficiency of carbon capture technology, which is a key method for reducing greenhouse gas emissions from factories and power plants.

In the filing’s own words

A carbon dioxide absorbent using an aqueous potassium carbonate solution, a carbon dioxide capture process using the carbon dioxide absorbent, and a carbon dioxide capture system. The carbon dioxide absorbent includes an aqueous potassium carbonate solution including a carbonic anhydrase activity enhancer; and one or more nanoporous structures, where the one or more nanoporous covalently bonded structure includes carbonic anhydrase. The carbonic anhydrase activity enhancer includes a secondary amine compound, where the secondary amine compound may be present at a concentration of about 20 millimolar to about 90 millimolar in the aqueous potassium carbonate solution.

What exactly they claim (claim 1)

1. A carbon dioxide absorbent using an aqueous potassium carbonate solution, the carbon dioxide absorbent comprising: the aqueous potassium carbonate solution including a carbonic anhydrase activity enhancer; and one or more nanoporous structures, wherein the one or more nanoporous structures comprise carbonic anhydrase; wherein the carbonic anhydrase activity enhancer comprises a secondary amine compound, and the secondary amine compound is present in the aqueous potassium carbonate solution at a concentration of about 20 millimolar to about 90 millimolar.
