45% ntawm cov pa roj carbon emissions nyob rau hauv lub ntiaj teb no kev lag luam sector yog los ntawm cov txheej txheem ntawm cov hlau, hluavtaws ammonia, ethylene, cement, thiab lwm yam. Hydrogen zog muaj ob tug cwj pwm ntawm industrial raw cov ntaub ntawv thiab cov khoom siv zog, thiab suav hais tias yog ib qho tseem ceeb thiab ua tau. daws kom sib sib zog nqus decarbonization ntawm kev lag luam. Nrog rau qhov poob qis ntawm cov nqi hluav taws xob txuas ntxiv dua tshiab, qhov teeb meem ntawm tus nqi ntsuab hydrogen yuav maj mam daws, thiab "kev lag luam + ntsuab hydrogen" yuav tsum nkag mus rau hauv kev lag luam tshuaj los pab cov tuam txhab tshuaj ua kom muaj nuj nqis rov qab.
Qhov tseem ceeb ntawm "ntsuab hydrogen" nkag mus rau hauv cov txheej txheem tsim khoom raws li cov khoom siv tshuaj lom neeg rau kev lag luam tshuaj thiab hlau thiab hlau yog tias nws tuaj yeem ua tau raws li cov kev xav tau ntawm kev siv hluav taws xob thiab cov pa roj carbon emissions tib lub sijhawm, thiab tseem muab cov txiaj ntsig kev lag luam ntxiv rau cov lag luam. muab chaw lag luam loj hlob tshiab.
Tsis muaj qhov tsis ntseeg tias kev lag luam tshuaj lom neeg yog qhov tseem ceeb. Hauv 10 xyoo tom ntej, cov khoom lag luam xav tau ntawm kev lag luam tshuaj yuav loj hlob tsis tu ncua, tab sis vim yog kev hloov kho ntawm cov qauv tsim thiab cov qauv khoom, nws tseem yuav muaj qee yam cuam tshuam rau qhov kev thov rau hydrogen. Tab sis zuag qhia tag nrho, kev lag luam tshuaj nyob rau hauv 10 xyoo tom ntej no yuav yog ib tug loj nce nyob rau hauv qhov kev thov rau hydrogen. Nyob rau hauv lub sij hawm ntev, nyob rau hauv lub xoom-carbon yuav tsum, hydrogen yuav dhau los ua cov ntaub ntawv raw tshuaj, thiab txawm tias hydrogen chemical kev lag luam.
Hauv kev xyaum, tau muaj cov kev pab cuam thiab kev ua qauv qhia uas siv ntsuab hydrogen ua raw khoom ntxiv rau cov txheej txheem thee chemical, txhim kho kev lag luam siv carbon atoms, thiab txo cov pa roj carbon dioxide. Tsis tas li ntawd, muaj ntsuab hydrogen los tsim cov tshuaj ammonia los tsim "ntsuab ammonia", ntsuab hydrogen los tsim methanol los tsim "ntsuab cawv" thiab lwm yam kev daws teeb meem kuj tau ua nyob rau hauv Suav teb. Nws cia siab tias nyob rau hauv 10 xyoo tom ntej, cov thev naus laus zis saum toj no yuav tsum tau ua tiav ntawm tus nqi.
Nyob rau hauv "hlau thiab steel kev lag luam muaj peev xwm txo tau", "kom ntseeg tau tias xyoo-rau-xyoo poob ntawm cov khoom siv hlau tsis zoo" cov cai, nrog rau kev maj mam nce qib ntawm cov khoom siv rov ua dua tshiab thiab hydrogen ncaj qha txo cov hlau thiab lwm yam thev naus laus zis, kev lag luam xav tau. mus rau yav tom ntej raws li tsoos blast furnace hlau smelting yuav tsum tau coking peev yuav poob, coking by-product hydrogen poob, tab sis raws li hydrogen thov ntawm hydrogen ncaj qha txo hlau technology, hydrogen metallurgy yuav tau txais kev loj hlob. Txoj kev no ntawm kev hloov cov pa roj carbon nrog hydrogen raws li kev txo tus neeg sawv cev hauv kev tsim hlau ua rau cov txheej txheem hlau tsim cov dej es tsis txhob carbon dioxide, thaum siv hydrogen los muab cov cua kub zoo, yog li txo qis cov pa hluav taws xob hauv tsev cog khoom, uas suav tias yog ntsuab. txoj kev tsim khoom rau kev lag luam steel. Tam sim no, ntau lub tuam txhab steel hauv Suav teb tau mob siab rau sim.
Kev lag luam xav tau rau kev lag luam ntsuab hydrogen tau maj mam ua kom pom tseeb, kev cia siab rau kev lag luam yav tom ntej yog dav. Txawm li cas los xij, muaj peb yam xwm txheej rau kev siv loj ntawm hydrogen raws li cov khoom siv raw hauv cov tshuaj thiab cov hlau: 1. Tus nqi yuav tsum tsawg, tsawg kawg nws tsis yog qis dua tus nqi ntawm grey hydrogen; 2, qib qis carbon emission (xws li xiav hydrogen thiab ntsuab hydrogen); 3, lub neej yav tom ntej "dual carbon" txoj cai tswjhwm yuav tsum hnyav txaus, txwv tsis pub tsis muaj kev lag luam yuav pib hloov kho.
Tom qab xyoo ntawm txoj kev loj hlob, lub zog tauj dua tshiab lub zog tsim kev lag luam tau nkag mus rau hauv ib theem ntawm kev loj hlob, tus nqi ntawm photovoltaic fais fab tuag thiab cua tshuab hluav taws xob tseem poob qis. Tus nqi ntawm "ntsuab hluav taws xob" txuas ntxiv poob qis uas txhais tau hais tias ntsuab hydrogen yuav nkag mus rau hauv kev lag luam thiab maj mam ua ib qho chaw ruaj khov, tsis tshua muaj nqi, loj-loj daim ntawv thov ntawm cov khoom siv raw khoom. Hauv lwm lo lus, tus nqi qis ntsuab hydrogen yuav tsum rov tsim kho cov qauv kev lag luam tshuaj thiab qhib cov kev tshiab rau kev lag luam tshuaj lom neeg kev loj hlob!
