Real flue gas CO₂ hydrogenation to formate by an enzymatic reactor using O₂- and CO-tolerant hydrogenase and formate dehydrogenase.

ABSTRACT: It is challenging to capture carbon dioxide (CO₂), a major greenhouse gas in the atmosphere, due to its high chemical stability. One potential practical solution to eliminate CO₂ is to convert CO₂ into formate using hydrogen (H₂) (CO₂ hydrogenation), which can be accomplished with inexpensive hydrogen from sustainable sources. While industrial flue gas could provide an adequate source of hydrogen, a suitable catalyst is needed that can tolerate other gas components, such as carbon monoxide (CO) and oxygen (O₂), potential inhibitors. Our proposed CO₂ hydrogenation system uses the hydrogenase derived from Ralstonia eutropha H16 (ReSH) and formate dehydrogenase derived from Methylobacterium extorquens A
