Cov engineers tau tsim cov txheej txheem ua tau zoo los hloov cov pa roj carbon dioxide rau hauv roj. Txoj kev koom nrog ncaj qha hloov cov roj tsev cog khoom rau hauv formate, cov roj khoom uas tuaj yeem khaws cia tsis tu ncua thiab siv rau cua sov tsev lossis hluav taws xob kev lag luam.
Cov kws tshawb fawb los ntawm MIT thiab Harvard University tau ua tiav qhov tseem ceeb hauv daim teb no. Lawv tau ua tiav cov txheej txheem hauv qhov chaw sim me me, uas suav nrog kev ntes cov pa roj thiab electrochemically hloov nws mus rau hauv cov khoom tsim cov hmoov. Cov hmoov no tuaj yeem siv rau hauv cov roj hlwb los tsim hluav taws xob. Cov kws tshawb fawb ntseeg tias cov txheej txheem tuaj yeem ua kom loj thiab tuaj yeem muaj peev xwm muab cov cua sov tsis muaj hluav taws xob thiab lub zog rau cov tsev neeg, nrog rau kev siv rau hauv kev lag luam lossis kab sib chaws.
Formate roj muaj ntau yam kev siv, xws li los ntawm cov chav me me rau cov tsev mus rau qhov loj-scale industrial lossis grid-scale cia systems. Thaum pib, daim ntawv thov hauv tsev tuaj yeem koom nrog cov khoom siv hluav taws xob txog qhov loj ntawm lub tub yees, siv los ntes cov pa roj carbon dioxide thiab hloov mus rau hauv formate, uas tuaj yeem muab khaws cia rau hauv av lossis lub tsev tso tsheb hlau luam. Thaum xav tau, cov hmoov hmoov yuav muab tov nrog dej thiab muab tso rau hauv roj hlwb los muab lub zog thiab cua sov. Cov kws tshawb fawb pom qhov no yog kev ua qauv qhia hauv zej zog lossis tsev neeg, tab sis lawv kuj ntseeg tias nws tuaj yeem muaj txiaj ntsig zoo rau cov chaw tsim khoom lossis kab sib chaws yav tom ntej.
Formate fuels muaj ntau qhov zoo, xws li lawv cov xwm txheej zoo thiab ruaj khov, ua rau lawv muaj lub zog txaus nyiam. Potassium formate thiab sodium formate twb tau tsim tawm hauv kev lag luam thiab feem ntau yog siv los ua de-icing agents rau txoj kev thiab kev taug kev. Lawv yog cov tsis muaj tshuaj lom, tsis muaj hluav taws kub, yooj yim rau khaws thiab thauj, thiab tuaj yeem nyob ruaj khov hauv cov thawv hlau tsis tu ncua rau lub hlis lossis ntau xyoo.
Kev ua haujlwm ntawm cov engineers no tau txais kev txhawb nqa los ntawm US Department of Energy's Office of Science. Ted Sargent, tus xibfwb ntawm chemistry thiab hluav taws xob thiab khoos phis tawj engineering ntawm Northwestern University uas tsis koom nrog txoj kev tshawb fawb, tau hais tias lub tswv yim ntawm kev lag luam formate yog qhov txaus nyiam thiab cov kws tshawb fawb tau ua kom pom kev txhim kho cov kua-rau-kua hloov pauv los ntawm bicarbonate feedstock rau formate. , ua pov thawj tias cov roj no tuaj yeem siv rau kev tsim hluav taws xob yav tom ntej.
