Tesla CEO Elon Musk tso tseg hydrogen ua lub cuab yeej rau lub zog cia

Tesla CEO Elon Musk tau rov hais dua nws qhov kev tsis ntseeg txog hydrogen lub luag haujlwm hauv kev npaj hloov mus rau lub neej tom ntej zoo dua, piav qhia nws tias "qhov ruam tshaj plaws uas kuv tuaj yeem xav txog rau lub zog cia." 

Thaum lub sij hawm xam phaj ntawm lub Lub Sijhawm Nyiaj Txiag Yav Tom Ntej ntawm Lub Tsheb Sib Tham Hnub Tuesday, Musk tau nug yog tias nws xav tias hydrogen muaj lub luag haujlwm los ua kom nrawm rau kev hloov pauv ntawm cov fossil fuels.

"Tsis yog," nws teb. "Kuv yeej tsis tuaj yeem hais txog qhov txaus txaus - pes tsawg zaus kuv tau nug txog hydrogen, nws yuav yog ... nws zoo dua 100 zaug, tej zaum 200 zaug," nws hais. "Nws yog ib qho tseem ceeb kom nkag siab tias yog tias koj xav tau lub zog cia, hydrogen yog qhov kev xaiv tsis zoo."

Tshaj tawm ntawm nws qhov kev sib cav, Musk tau hais ntxiv tias "cov tank loj" yuav tsum tau tuav hydrogen hauv cov kua dej. Yog tias nws yuav tsum tau khaws cia rau hauv daim ntawv gaseous, "txawm tias loj dua" tso tsheb hlau luam yuav xav tau, nws hais.

Piav qhia los ntawm International Energy Agency raws li "muaj peev xwm ntau lub zog hluav taws xob," hydrogen muaj ntau yam kev siv thiab tuaj yeem siv rau hauv cov haujlwm xws li kev lag luam thiab thauj.

Xyoo 2019, IEA tau hais tias hydrogen yog "ib qho ntawm cov kev xaiv tseem ceeb rau khaws cia lub zog los ntawm kev rov ua dua tshiab thiab zoo li cog lus tias yuav yog qhov kev xaiv qis tshaj plaws rau khaws cia hluav taws xob ntau hnub, lub lis piam lossis ntau hli."

Lub koom haum Paris-based ntxiv hais tias ob qho tib si hydrogen thiab hydrogen-raws li cov roj hluav taws xob tuaj yeem "hloov lub zog los ntawm cov khoom siv txuas ntxiv mus ntev - los ntawm thaj chaw uas muaj hnub ci thiab cua ntau, xws li Australia lossis Latin America, mus rau lub zog tshaib plab ntau txhiab kilometers. deb."

Musk muaj keeb kwm ntawm nthuav tawm cov kev xav muaj zog txog hydrogen thiab hydrogen roj hlwb.

Ob peb xyoos dhau los, thaum cov ntsiab lus tau tshwm sim thaum muaj kev sib tham nrog cov neeg sau xov xwm ntawm Automotive News World Congress, lub tsheb fais fab tau piav qhia txog cov roj hluav taws xob hydrogen li "ua dag heev."

Thaum Lub Rau Hli 2020 nws tweeted "fuel cells = ruam muag,"  ntxiv rau lub Xya hli ntuj xyoo ntawd: "Hydrogen fools muag tsis muaj txiaj ntsig." Txiav txim los ntawm nws cov lus nyob rau lub lim tiam no, nws tseem tsis ntseeg txog hydrogen.

"Nws tsis tshwm sim hauv ntiaj teb, yog li koj yuav tsum tau faib dej nrog electrolysis lossis tawg hydrocarbons," nws hais rau Lub Sijhawm Nyiaj Txiag.

"Thaum koj tab tom tawg hydrocarbons, koj yeej tsis tau daws cov teeb meem roj fossil, thiab kev ua haujlwm ntawm electrolysis tsis zoo."

Niaj hnub no, feem ntau ntawm hydrogen ntau lawm yog raws li fossil fuels. Lwm txoj kev ntawm kev tsim khoom suav nrog kev siv electrolysis, nrog rau cov hluav taws xob tam sim no faib dej rau hauv oxygen thiab hydrogen.

Yog tias hluav taws xob siv hauv cov txheej txheem no los ntawm cov khoom siv txuas ntxiv xws li cua lossis hnub ci ces qee tus hu nws ntsuab los yog txuas ntxiv hydrogen.

Hydrogen tej yaam num siv electrolysis tau nyiam los ntawm cov tuam txhab loj thiab cov thawj coj ua lag luam nyob rau xyoo tas los no, tab sis nws yuav tshwm sim Musk tsis yog kiv cua.

"Kev ua haujlwm ntawm electrolysis yog ... tsis zoo," nws hais rau Lub Sijhawm Nyiaj Txiag. “Yog li koj yeej siv ntau lub zog los… faib hydrogen thiab oxygen. Tom qab ntawd koj yuav tsum cais cov hydrogen thiab oxygen thiab nias nws - qhov no kuj siv zog ntau. "

"Thiab yog tias koj yuav tsum ua kua dej ... hydrogen, Au kuv tus Vajtswv," nws hais ntxiv. "Tus nqi ntawm lub zog yuav tsum tau ... ua hydrogen thiab tig mus rau hauv cov kua dej yog staggering. Nws yog qhov ruam tshaj plaws uas kuv tuaj yeem xav txog rau lub zog cia. "

Cov kev xav txawv

Musk tej zaum yuav tsis lees paub txog hydrogen lub luag haujlwm hauv kev hloov pauv lub zog, tab sis lwm cov suab nrov muaj kev cia siab me ntsis. Cov no suav nrog Anna Shpitsberg, uas yog tus pab cuam tus tuav ntaub ntawv rau kev hloov pauv hluav taws xob ntawm US Department of State.

Thaum lub rooj sib tham tsis ntev los no los ntawm CNBC's Hadley Gamble, Shpitsberg hu ua hydrogen "kev ua si-hloov thev naus laus zis uas hais lus rau ntau yam ntawm lwm qhov chaw ... vim tias nws muaj peev xwm underpin nuclear, nws muaj peev xwm underpin roj, nws muaj peev xwm underpin renewables, nws muaj peev xwm ntxuav ib feem zoo ntawm nws thiab thiaj li muaj peev xwm CCUS [carbon capture utilization thiab ruaj khov]."

Lwm qhov, Lub Ob Hlis pom Michele DellaVigna, Goldman Sachs ' Cov khoom lag luam ncaj ncees tus thawj coj ua lag luam rau thaj tsam EMEA, qhia txog lub luag haujlwm tseem ceeb uas nws xav tias yuav tau mus tom ntej.

"Yog tias peb xav mus rau net-zero peb ua tsis tau nws tsuas yog los ntawm lub zog tauj dua tshiab," nws hais.

DellaVigna tau hais tias "Peb xav tau ib yam dab tsi uas siv lub luag haujlwm niaj hnub no ntawm cov nkev ntuj, tshwj xeeb tshaj yog los tswj lub caij nyoog thiab sib cuam tshuam, thiab qhov ntawd yog hydrogen," DellaVigna tau sib cav, piav qhia txog hydrogen li "lub zog muaj zog heev."

Tus yuam sij, nws hais tias, yog "tsim nws yam tsis muaj CO2 emissions. Thiab yog vim li cas peb tham txog ntsuab, peb tham txog xiav hydrogen. "

Blue hydrogen yog hais txog hydrogen uas ua los ntawm cov roj ntsha ntuj - cov roj fossil - nrog rau CO2 emissions generated thaum tus txheej txheem ntes thiab khaws cia. Tau muaj kev sib cav uas raug nqi nyob ib ncig ntawm lub luag hauj lwm xiav hydrogen tuaj yeem ua si hauv decarbonization ntawm tib neeg.

"Txawm hais tias peb ua nws nrog electrolysis lossis peb ua nrog carbon capture, peb yuav tsum tsim hydrogen hauv txoj kev huv," DellaVigna hais. "Thiab ib zaug peb muaj nws, kuv xav tias peb muaj kev daws teeb meem uas tuaj yeem dhau los, ib hnub, tsawg kawg 15% ntawm lub ntiaj teb kev lag luam hluav taws xob uas txhais tau tias nws yuav yog ... ntau dua trillion duas lag luam ib xyoos twg."
