Nyob rau nruab nrab Lub Cuaj Hli, Tanager -1 satellite xa rov qab nws thawj cov duab los ntawm qhov siab ntawm 325 mais saum lub ntiaj teb saum npoo av. Cov yeeb yuj duab ntawm Karachi, Pakistan rov qab los ua ntej. Tab sis tom qab ntawd Planet Labs, uas tsim lub satellite ua ke nrog Carbon Mapper thiab NASA's Jet Propulsion Laboratory, tso tawm cov duab ntawm Kendal, South Africa, thiab Texas Permian Basin. Cov duab zoo nkauj ntawm Texas muaj qhov sib sib zog nqus xiav plume, uas yog methane los ntawm cov roj thiab roj ntau lawm.

Qhov thib ob ntau tshaj plaws ntawm tib neeg txuas nrog tsev cog khoom roj tom qab cov pa roj carbon dioxide, methane yog ze li 30 npaug ntawm qhov muaj zog ntawm cov cua kub hauv ntiaj teb, raws li Lub Chaw Tiv Thaiv Ib puag ncig. Nws yog ib qho byproduct ntawm cov txheej txheem kev lag luam thiab kev ua liaj ua teb, thiab tseem yog tsim los ntawm kev decomposition ntawm cov khoom siv organic, xws li ntawm qhov chaw pov tseg.
Txawm li cas los xij, methane tau txais kev saib xyuas tsawg dua los ntawm cov neeg tsim kho tshiab hauv cov pa roj carbon monoxide thiab tshem tawm qhov chaw tshaj li carbon dioxide. Tab sis rau San Mateo, California-based startup Windfall Bio, methane yog tag nrho zaj dab neeg.
McKenzie Wilson, Windfall Bio tus thawj coj ntawm carbon accounting hais tias "Nws yog tiag tiag nce mus rau saum cov txheej txheem, tab sis tsis ceev txaus," hais tias McKenzie Wilson, Windfall Bio tus thawj coj ntawm carbon accounting. Nws hais tias nws suav tias yog "tus neeg tua neeg uas ntsiag to."

Tab sis Windfall Bio tau tsim ib txoj hauv kev los ntes thiab hloov methane rau hauv cov khoom uas muaj nqi tiag tiag: chiv. Wilson hais tias "Fertilizer yog lub zeem muag mus ntev thiab kev npaj," Wilson hais. "Nyob rau lub sijhawm ze, cov credits carbon yeej ua lub luag haujlwm." Nws hais ntxiv tias qee qhov chiv yuav raug muag thaum pib, thiab.
Windfall Bio siv qhov nws hu ua "mems"-lossis methane-noj-microbes-ua nws txoj haujlwm "dub". Ua ntej nws tsoo cov huab cua, methane los ntawm cov roj ntes cov tshuab ntawm cov chaw pov tseg, cov pas dej hauv cov liaj teb lossis cov pa taws tuaj yeem raug tso rau hauv Windfall bioreactor, uas muaj cov microbes. Lawv haus methane ua ib qho kev yug me nyuam, thiab thaum lawv yug me nyuam, lawv dhau los ua nitrogen-nplua nuj biomass uas tuaj yeem siv lossis muag ua chiv. Ib tus neeg hais xov xwm Windfall tau hais ntxiv tias "mems" tuaj yeem siv ncaj qha mus rau thaj chaw thiab rub methane los ntawm huab cua.

"Lub zeem muag yog kev faib cov chiv uas koj muaj ntau qhov chaw ntawm methane-ua liaj ua teb thiab cov chaw pov tseg, cov chaw siv roj av-koj tuaj yeem ntes tau cov pa, tso rau hauv bioreactor," Wilson hais. Thaum sau lawv txoj kev loj hlob, muaj "kev tsim cov chiv hauv zos."
Windfall Bio tshaj tawm txog $ 28 lab nyob rau hauv ib qho kev sib koom ua ke ntawm cov nyiaj hauv lub Plaub Hlis thiab suav nrog Prelude Ventures, Amazon's Climate Pledge Fund, thiab Bill Gates 'Txoj Kev Sib Tw Zog ntawm nws cov tub ua lag luam. Lub tuam txhab kuj tau tshaj tawm qhov tshiab, lub xeev-of-the-art kev tshawb fawb thiab kev loj hlob chaw hauv San Mateo, California, thaum Lub Xya Hli.
Cov ntsiab lus dav dav yog qhov hnyav: Lub ntiaj teb kub siab tshaj 1.5 degrees Celsius siab tshaj cov qib ua ntej kev lag luam - ib qho kev lees paub thoob ntiaj teb rau kev ua kom sov - rau tag nrho lub xyoo txij lub Ib Hlis 2023 txog Lub Ib Hlis 2024, raws li European kev nyab xeeb txoj cai. Qhov kev nce qib no muaj cov kws tshawb fawb, cov thawj coj hauv ntiaj teb, thiab lwm tus neeg sib tw los nrhiav kev daws teeb meem los daws qhov sov. Ntau qhov kev siv zog no tau tsom mus rau carbon dioxide, tab sis methane yog thaj tsam ntawm kev txaus siab.
Piv txwv li, ntawm lub tuam txhab tshem tawm cov pa roj carbon monoxide Climeworks ' flagship Carbon Removal Summit ntawm Climate Week NYC, Bezos Earth Fund tus thawj coj ntawm tech acceleration Noël Bakhtian tau tham txog ib qho kev pib tshem tawm tsev cog khoom tsis ntev los no ntawm cov peev nyiaj pab dawb. "Nws kuj tseem tab tom saib qee qhov ntawm lwm cov pa roj hauv qhov chaw no. Nws tab tom saib, peb puas tuaj yeem txhim kho kev tshawb fawb ntawm methane tshem tawm thiab tshem tawm nitrous oxide, thiab xam seb puas muaj lub luag haujlwm rau lawv ua si," nws hais.
