Tsis ntev los no, Guizhou, Shandong thiab lwm qhov chaw tau tshaj tawm cov ntaub ntawv thov kev hloov pauv ntawm cov pa roj carbon tsawg ntawm "ob siab" (siab zog noj thiab emission siab) kev lag luam. Cov kev taw qhia kev xav txog kev ntxiv dag zog rau kev tswj hwm ntawm "ob lub siab" cov haujlwm tshaj tawm los ntawm cov tib neeg tsoomfwv ntawm Guizhou xeev tau hais tias los ntawm 2025, cov pa roj carbon emission siv ntawm qhov tseem ceeb "ob lub siab" kev lag luam yuav txo qis, thiab lub peev xwm ntawm ntsuab thiab qis. - carbon kev loj hlob yuav tsum tau txhim khu kev qha; Txoj kev npaj ua haujlwm rau kev hloov pauv hluav taws xob thiab kev txhim kho ntawm "ob lub siab" kev lag luam hauv Shandong xeev qhia tias "ob lub siab" kev lag luam yuav tsum ua tiav kev tshawb fawb ntsuab thiab qis-carbon technology thiab txhawb kev ua tiav ntawm ntsuab thiab qis-carbon technology.
Raws li cov lus qhia ntxiv dag zog rau kev tiv thaiv thiab kev tswj hwm ntawm ecological ib puag ncig qhov chaw ntawm kev siv hluav taws xob siab thiab kev tsim kho hluav taws xob siab tshaj tawm los ntawm Ministry of ecological ib puag ncig thaum Lub Rau Hli 2021, "ob lub siab" tej yaam num raug suav ib ntus los ntawm rau pawg kev lag luam, suav nrog thee fais fab, petrochemical, tshuaj, hlau thiab hlau, non-ferrous hlau smelting thiab cov ntaub ntawv hauv tsev. Ntawm lawv, kev lag luam hlau thiab hlau, uas yog lub hauv paus kev lag luam ntawm lub teb chaws kev lag luam, muaj kev xav tau ceev ceev rau kev hloov pauv ntawm cov pa roj carbon tsawg, thiab kev siv lub zog ntsuab hydrogen yuav yog txoj hauv kev tseem ceeb rau nws txoj kev hloov.
Daim ntawv thov ntawm hydrogen zog hauv kev lag luam hlau thiab hlau feem ntau suav nrog peb qhov chaw: hydrogen metallurgy, hydrogen zog thauj thiab steel dov ntau lawm.
Hauv kev lag luam ntawm hydrogen metallurgy, hydrogen zog yog siv hlau thiab hlau smelting, uas tuaj yeem paub cov hlau tsis tshua muaj carbon hlau los ntawm qhov chaw, thiab muaj ntau yam kev qhia hauv cov txheej txheem smelting. Hauv cov txheej txheem sintering, hydrogen tuaj yeem siv los ua cov roj sintering kom txo tau cov pa roj carbon ntau zog xws li coke hmoov / pulverized thee; Hauv cov txheej txheem blast furnace, hydrogen tuaj yeem siv los ua tus neeg sawv cev rau kev txhaj tshuaj blast furnace. Tsis tas li ntawd, lub zog hydrogen kuj tseem siv tau rau hauv cov txheej txheem uas tsis yog blasting tshuab xws li kev txo qis thiab smelting txo cov hlau ua.
Nyob rau hauv lub tshav pob ntawm hydrogen zog tsheb thauj mus los, hlau thiab steel kev lag luam belongs rau lub hnyav logistics kev lag luam. Lub logistics xav tau ib tuj ntawm cov hlau ntawm cov txheej txheem ntev hlau thiab steel kev lag luam tuaj yeem ncav cuag 4 ~ 5 npaug ntawm cov khoom tsim tawm. Txhua xyoo kev thauj mus los sab nraud ntawm Tuam Tshoj txoj kev lag luam hlau thiab hlau tuaj yeem ncav cuag 4 ~ 5 billion tons. Ntxiv rau qhov kev hloov pauv ntawm hydrogen zog rau ib txwm muaj zog hauv kev lag luam tsheb, cov tsheb tsis yog txoj kev tsheb ciav hlau thiab cov tsheb ciav hlau siv los ntawm cov tuam txhab hlau thiab hlau tuaj yeem siv los ua cov ntawv thov ntawm hydrogen zog.
Nyob rau hauv lub tshav pob ntawm steel rolling ntau lawm, hydrogen zog yog tsuas yog siv nyob rau hauv txias dov ntau lawm kab, thiab hydrogen yuav tsum tau raws li annealing shielding gas nyob rau hauv txias dov annealing txheej txheem.
Txhawm rau txhawb kev txhawb nqa thiab kev siv ntsuab hydrogen hauv kev lag luam hlau thiab hlau, nws yog ib qho tsim nyog yuav tsum tau ua cov kev tshawb fawb txog kev npaj hydrogen, khaws cia, kev thauj mus los thiab kev siv hauv kev lag luam hlau thiab hlau raws li "ob chav carbon" lub hom phiaj. Nyob rau hauv cov cheeb tsam uas nplua nuj nyob rau hauv cov cua, hnub ci thiab hydropower cov kev pab cuam, nws yog ib qhov tsim nyog yuav tsum tau tsom mus rau kev txhawb nqa kev ua yeeb yam ntawm cov thev naus laus zis tseem ceeb xws li hydrogen ntau lawm los ntawm cov dej electrolytic uas tsis muaj zog siv thiab lub neej ntev lub zog tauj dua tshiab, maj mam nthuav cov qauv qhia, thiab txhim kho qib. ntawm low-carbon clean hydrogen technology thiab khoom siv. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog los tshawb nrhiav kev tsim lub zog tshiab hydrogen ntau lawm puag ncig cov tuam txhab hlau thiab hlau nrog loj hydrogen zog thov teev.
