Lub 20 megawatt hydrogen electrolyzer piav raws li "ib qho ntawm lub ntiaj teb loj tshaj plaws" tau pib ua haujlwm, lub zog loj Shell tau hais rau hnub Friday.
Nyob rau hauv Zhangjiakou, Hebei Province, Suav teb, lub electrolyzer yuav tsim ntsuab hydrogen rau roj cell tsheb siv nyob rau hauv Zhangjiakou qhov kev sib tw cheeb tsam thaum lub caij ntuj no Olympics, uas yuav tsum tau qhib rau lub Ob Hlis 4. Thaum cov kev ua si tiav, coj mus muag thiab pej xeem thauj yuav. siv cov hydrogen.
Hauv tsab ntawv tshaj tawm, Wael Sawan, Shell's integrated gas, renewable and energy solutions director, said the electrolyzer yog "qhov loj tshaj plaws hauv peb cov ntaub ntawv rau hnub tim."
"Peb pom cov hauv kev thoob plaws cov khoom siv hydrogen hauv Suav teb, suav nrog nws cov khoom tsim, khaws cia thiab xa khoom," Sawan tau hais.
Lub chaw nyob hauv Suav teb txuas nrog kev sib koom ua lag luam tsim nyob rau xyoo 2020 ntawm Shell Tuam Tshoj thiab Zhangjiakou City Transport Construction Investment Holding Group Co. Ltd.
Hydrogen, uas muaj ntau hom kev siv thiab tuaj yeem siv rau hauv ntau qhov kev lag luam, tuaj yeem tsim tau ntau txoj hauv kev. Ib txoj hauv kev suav nrog kev siv electrolysis, nrog rau hluav taws xob tam sim no faib dej rau hauv oxygen thiab hydrogen.
Yog tias cov hluav taws xob siv hauv cov txheej txheem no los ntawm qhov chaw txuas ntxiv dua tshiab xws li cua lossis hnub ci ces qee qhov hu nws ntsuab lossis hydrogen txuas ntxiv. Lub tshuab hluav taws xob hauv Zhangjiakou yuav siv lub zog cua ntawm ntug dej hiav txwv, Shell tau hais.
Thaum muaj kev zoo siab nyob rau hauv qee lub quarters txog ntsuab hydrogen lub peev xwm, feem ntau ntawm hydrogen tiam tam sim no raws li fossil fuels.
Nyob rau lub sijhawm tsis ntev los no, qee tus thawj coj ua lag luam tau hais txog cov teeb meem uas lawv xav tias tab tom ntsib cov kev lag luam ntsuab hydrogen. Nyob rau lub Kaum Hli 2021, piv txwv li, CEO ntawm Siemens Energy tau hais rau CNBC tias tsis muaj "tsis muaj teeb meem kev lag luam" rau nws nyob rau lub sijhawm no.
Niaj hnub no, ntau yam xim - suav nrog xim av, xiav, grey thiab liab, rau npe rau ob peb - yog siv los sib txawv ntawm ntau txoj kev tsim khoom rau hydrogen.
Lub Kaum Ob Hlis Ntuj tas los, CEO ntawm German lub tuam txhab hluav taws xob RWE tau piav qhia rau CNBC tias nws yog ib qho tseem ceeb kom ua raws li cov cai xim.
"Thaum kawg, tag nrho cov hydrogen yuav tsum yog ntsuab, vim hais tias ntsuab hydrogen yog tib roj uas yog ... tag nrho decarbonized," Markus Krebber hais. Lub sijhawm no, kev lag luam yuav tsum tau txiav txim siab los nqis peev hauv cov chaw tshiab thiab ua kom lawv "H2 npaj."
"Tau kawg, tsis muaj hydrogen ntsuab txaus muaj nyob rau lub sijhawm luv luv, yog li koj yuav tsum tso cai rau lawv khiav nws thawj zaug ntawm cov pa roj carbon monoxide ces, tej zaum, ntawm tag nrho lwm cov xim [ntawm] hydrogen ... tshwj xeeb tshaj yog xiav," nws hais. "Tab sis lub sijhawm ntsuab hydrogen muaj, rau qhov xav tau, lawv yuav tsum hloov mus rau ntsuab hydrogen."
Blue hydrogen yog hais txog hydrogen uas ua los ntawm cov roj ntsha ntuj - cov roj fossil - nrog rau CO2 emissions generated thaum lub sij hawm tus txheej txheem ntes thiab khaws cia.
Nyuam qhuav pib lub hlis no, nws tau tshaj tawm tias ib qho ntawm tib lub chaw hauv ntiaj teb uas siv carbon capture thiab storage technology (CCS) los txo cov emissions ntawm hydrogen ntau lawm tau pom tias emissions ntau lub tsev xog paj emissions tshaj nws captures.
Lub Quest cog hauv Alberta, Canada, uas yog Shell thiab tsim los ntes cov pa roj carbon emissions los ntawm cov roj xuab zeb ua haujlwm thiab ruaj ntseg khaws cia hauv av, yav tas los tau tshaj tawm tias yog "tus piv txwv zoo" ntawm CCS ua haujlwm li cas los txo cov pa roj carbon monoxide.
Txawm li cas los xij, kev tshawb nrhiav los ntawm pab pawg saib xyuas Global Witness, luam tawm lub lim tiam dhau los, tau pom tias thaum 5 lab tons ntawm carbon dioxide tau raug tiv thaiv los ntawm kev khiav mus rau hauv huab cua ntawm cov nroj tsuag txij li xyoo 2015, nws kuj tau tso tawm 7.5 lab metric tons ntawm tsev cog khoom gases dua tib yam. lub sij hawm.
Nws txhais tau tias tsuas yog 48% ntawm cov nroj tsuag cov pa roj carbon monoxide raug ntes, raws li tsab ntawv ceeb toom. Hauv kev teb rau tsab ntawv ceeb toom, tus cev lus rau Shell tau hais rau CNBC ntawm email tias Kev Tshawb Fawb Ntiaj Teb yog "tsis ncaj ncees lawm" thiab tau hais tias qhov chaw Quest tau tsim los txhawm rau ntes ib feem peb ntawm cov pa roj carbon dioxide.
Shell's Quest CCS qhov chaw qhib thaum xyoo 2015 thiab yog ib feem ntawm pab pawg Scotford complex, qhov twg hydrogen yog tsim los siv rau hauv refining roj sands bitumen (ib hom roj av deposit). Quest cog tsis npog cov emissions rau tag nrho cov chaw.
"Peb qhov chaw Quest tau tsim los rau qee xyoo dhau los ua ib txoj haujlwm ua qauv qhia los ua pov thawj CCS lub tswv yim, thaum ntes ib feem peb ntawm CO2 emissions. Nws tsis yog qhov chaw tsim khoom siv hydrogen, "tus cev lus ntawm Shell tau hais.
