Ob lub tuam txhab tau sim kev siv hydrogen los ua kom sov hlau ntawm chaw nyob hauv Sweden, qhov kev txav uas thaum kawg tuaj yeem pab ua kom kev lag luam muaj kev nyab xeeb.
Nyuam qhuav pib lub lim tiam no Ovako, uas tshwj xeeb hauv kev tsim hom hlau tshwj xeeb hu ua engineering steel, hais tias nws tau koom tes nrog Linde Gas rau txoj haujlwm ntawm Hofors dov lub tshuab.
Rau qhov kev sim siab, hydrogen tau siv los ua roj siv hluav taws xob ua kom muaj cua sov es tsis txhob siv roj av roj. Ovako nrhiav kom pom cov txiaj ntsig ib puag ncig ntawm kev siv hydrogen hauv cov txheej txheem kev txuas ntxiv, ceeb toom tias tsuas yog tsim cov pa tawm yog dej tso tawm.
"Qhov no yog qhov kev loj hlob tseem ceeb rau kev lag luam steel," Göran Nyström, Ovako tus thawj coj tus thawj coj rau pawg kev lag luam thiab thev naus laus zis, tau hais hauv nqe lus.
"Nws yog thawj zaug uas hydrogen tau siv los ua kom sov hlau hauv ib puag ncig kev tsim khoom," nws hais ntxiv.
"Ua tsaug rau qhov kev sim siab, peb paub tias hydrogen yuav siv tau yooj yim thiab hloov tau, tsis muaj kev cuam tshuam rau cov hlau tsis zoo, uas yuav txhais tau tias yuav txo qis cov pa roj carbon ntau ntau."
Ib yam li nrog ntau ntu kev lag luam, kev lag luam steel muaj qhov cuam tshuam zoo rau ib puag ncig. Raws li Lub Koom Haum Ntiaj Teb Cov Hlau, nyob rau nruab nrab, 1.85 metric tons ntawm cov pa roj carbon dioxide tau raug tso tawm rau txhua qhov kev sib tw hauv cov hlau tsim hauv xyoo 2018. Lub Koom Haum Hluav Taws Xob Thoob Ntiaj Teb tau piav txog cov haujlwm steel yog "muaj kev cia siab rau ntawm cov thee, uas muab 75% ntawm lub zog thov. "
Cov roj rau lub neej yav tom ntej?
Cov European Commission tau piav qhia txog hydrogen ua cov khoom siv hluav taws xob nrog "lub peev xwm zoo rau kev huv, txuag hluav taws xob hauv chaw ruaj ruaj, nqa khoom thiab thauj cov ntawv thov."
Thaum hydrogen tsis ntseeg qhov muaj peev xwm, muaj qee qhov kev sib tw thaum nws los tsim nws.
Raws li Asmeskas Lub Tsev Haujlwm Saib Xyuas Lub Zog tau sau tseg, hydrogen tsis ib txwm "muaj ntawm nws tus kheej hauv qhov" thiab xav tau los ntawm cov khoom sib txuas uas muaj nws.
Tus naj npawb ntawm cov khoom siv - los ntawm cov roj av thiab hnub ci, txhawm rau kev sov siab - tuaj yeem tsim cov tshuaj hydrogen. Yog tias cov khoom siv hluav taws xob tshiab siv hauv nws cov khoom, nws dubbed "ntsuab hydrogen."
Thaum tus nqi tseem yog qhov kev txhawj xeeb, ob peb lub xyoo dhau los tau pom hydrogen siv nyob rau ntau qhov chaw ntawm kev thauj neeg xws li tsheb ciav hlau, tsheb thiab tsheb npav.
Hauv qhov piv txwv tseeb ntawm cov tuam txhab kev thauj khoom loj coj cov kauj ruam los thawb lub thev naus laus zis mus rau hauv cov cuab yeej tseem ceeb, Volvo Group thiab Daimler Truck tsis ntev los no tau tshaj tawm cov kev npaj rau kev sib koom tes tsom rau hydrogen roj-cell technology.
Ob lub tuam txhab tau hais tias lawv tau tsim txoj haujlwm 50/50 kev sib koom tes, nrhiav "tsim, tsim thiab ua lag luam roj cell system rau cov cuab yeej siv hnyav tsheb thiab lwm yam kev siv."
