-
Kev siv dej refueling yog kim thiab nyuaj.
Hydrogen-powered tsheb tseem tsis tau hloov roj tsheb, vim zoo peb tab tom yuav nkag rau hauv. Tab sis li cas txog tsheb ciav hlau?
Lub teb chaws Yelemees tau xa 14 lub tsheb ciav hlau hydrogen-powered nyob rau hauv nws thaj tsam Lower Saxony, hloov lub tshuab hluav taws xob rau ntawm rau caum-mais network. Hydrogen yog xoom-emissions roj thiab muaj peev xwm zoo piggyback ntawm cov uas twb muaj lawm diesel refueling infrastructure. Nws zoo li qhov kev hloov pauv zoo tshaj plaws rau cov tsheb roj, ib yam nkaus, vim tias peb yuav tsis tas yuav hloov tag nrho cov kev them nqi hluav taws xob zoo li peb yuav rau tsheb fais fab. Tab sis qhov tseeb, raws li koj tau twv, yog qhov nyuaj dua.
"Nyob ntawm nws lub ntsej muag, sau nrog hydrogen zoo li sau nrog roj. Koj tso nws rau hauv, thiab tawm koj mus," Arnas Vasiliauskas, tus tsim ntawm CarVertical, hais rau Lifewire ntawm email. "Thiab cov tsheb siv hydrogen kuj zoo siab heev rau kev siv. Lawv yog qhov sib sib zog nqus thiab muaj cov khoom txav tsawg dua, yog li tsis muaj kev vibration, ua rau cov tsheb hydrogen uas twb muaj lawm zoo kawg nkaus nyob ntsiag to thiab du rau kev tsav tsheb."
Nws yog Gas
Tam sim ntawd, yam nyuaj. Gas, txawm tias nws lub npe, yog cov kua ntawm qhov kub thiab txias, qhov hydrogen yuav tsum tau khaws cia rau hauv lub siab loj kom nws nyob hauv lub xeev ua kua. Thiab hydrogen tseem nyuaj dua li cov roj av liquefied roj av (LPG).
"Txawm hais tias nws yuav siv sijhawm tsib feeb [kom puv], qhov chaw them nyiaj rau hydrogen yog kim heev vim tias lawv yuav tsum ua haujlwm ntawm qhov kub siab heev," tus neeg nyiam tsheb Petar Dzaja hais rau Lifewire ntawm email. "Piv txwv li, lub siab ntawm cov roj hauv ib lub tsheb LPG yog nyob ib ncig ntawm 10 bar [145psi], thaum nyob hauv cov tsheb hydrogen, nws yog 700 bar [10, 000 psi]."
Qhov no kuj txhais tau hais tias lub twj tso kua mis hydrogen nqi ntau dua li lub twj tso kua mis yooj yim, thiab qhov ntawd yog ua ntej peb mus rau tus txiv neej uas hais txog kev haus luam yeeb thaum nws gasses nws lub tsheb.
"Hydrogen tsis tuaj yeem muab faib los ntawm cov txheej txheem uas twb muaj lawm xws li cov kav dej hauv av hauv av. Yuav tsum muaj kev faib khoom tshwj xeeb, tus nqi zoo," Ron Cogan ntawm Green Car Journal hais rau Lifewire ntawm email. "Qhov ntawd tsis yog hais tias nws ua tsis tau, lossis yuav tsum tsis ua, ua tiav … tsuas yog tias nws yuav ua rau muaj kev cog lus tseem ceeb nyiaj txiag. Lub sijhawm no, hydrogen raug thauj hauv cov tsheb loj, tsis zoo li roj av."
Yog vim li cas thiaj muaj qee lub tsheb uas siv hydrogen. Tsis muaj qhov twg los sau rau lawv, thiab thaum nws zoo li ib qho tuaj yeem hloov pauv-lossis ntxiv cov chaw nres tsheb roj uas twb muaj lawm, tus nqi siab heev uas tsis muaj leej twg yuav ua ua ntej muaj tsheb hydrogen ntxiv ntawm txoj kev.
Tsis huv
Lwm qhov downside ntawm hydrogen yog nws tsis tshwj xeeb ntsuab. Thaum koj hlawv nws nrog oxygen, nws hloov mus rau hauv dej (txawm tias nws tseem tuaj yeem tsim cov oxides ntawm nitrogen. Qhov ntawd yog qhov zoo thiab yog ib qho ntawm hydrogen qhov kev nyiam tshaj plaws. Qhov teeb meem yog tsim nws.
"Idrogen feem ntau siv niaj hnub no yog muab rho tawm los ntawm methane (cov roj fossil), thiab cov hydrogen no tsis suav tias yog 'ntsuab' roj, txawm tias hydrogen nws tus kheej yog cov roj huv huv zoo li nws tau siv. 'Green' hydrogen tuaj yeem tsim los ntawm electrolyzing dej los faib rau hauv hydrogen thiab oxygen, thiab qhov no tau tshawb nrhiav tiag tiag. Qhov kev sib tw yog tias cov txheej txheem yuav tsum muaj ntau lub zog (hluav taws xob) ua qhov no, "hais tias Cogan.
Qhov zoo tshaj plaws, lub zog ntawd yuav los ntawm cov khoom siv txuas ntxiv, tab sis ib zaug koj tab tom tsim lub zog txuas ntxiv mus, vim li cas ho tsis cia li xa cov xov hlau uas twb muaj lawm mus rau lub tsheb fais fab?
Txhua tus neeg
Tsheb ciav hlau, txawm li cas los xij, tej zaum yuav yog lwm qhov lus pom zoo. Ntau ntawm cov teb chaws Europe txoj kev tsheb ciav hlau yog hluav taws xob, tab sis yog tias koj pib los ntawm kos nrog lub tshuab hluav taws xob nkaus xwb, hydrogen tuaj yeem ua rau muaj kev nkag siab. Koj muaj tsawg dua cov ntsiab lus ntxiv los kho kom zoo, thiab raws li kev rov ua dua los ntawm cov kws tshaj lij, nws yuav tsum muaj kev nyab xeeb dua.
"Khiav lub tsheb ciav hlau ntawm hydrogen kuj yog ib qho yooj yim tab sis yuav tsum tau nqis peev tsawg dua hauv kev tsim kho vaj tse dua li cov xov hlau nyob saum taub hau. Koj khaws cov hydrogen txaus ntawm lub tsheb ciav hlau rau txhua txoj kev," hais Cogan.
Ntawm lub ntsej muag ntawm nws, sau nrog hydrogen zoo li sau nrog roj. Koj tso nws rau hauv, thiab tawm koj mus.
Hloov cov roj fossil yog qhov nyuaj vim tias lawv tau nkag mus rau hauv txhua yam peb ua. Peb xav tau kev hloov pauv loj dua li tsuas yog hloov ib hom roj nrog rau lwm qhov. Ib qho ntawm peb cov teeb meem loj tshaj plaws yog tsheb lawv tus kheej. Peb kuj tau siv rau lawv, thiab hauv qee thaj chaw, lub nroog tau tsim nyob ib puag ncig lawv.
Hloov chaw ntawm kev sib txuas ntawm cov chaw nres tsheb hydrogen lossis strip-mining lub ntiaj teb los tsim cov roj teeb txaus, peb yuav tsum saib cov tsheb ditching. Lub nroog tsis xav tau lawv, thiab hloov tsheb thauj neeg pej xeem mus rau hluav taws xob yog qhov ua tau tag nrho-trams thiab underground metro twb ua lawm.
Qhov tseeb yog qhov no: nws yog lub sijhawm los xav txog txoj hauv kev tshiab los ntxuav cov khoom.
