1.Dab tsi yog hydrogen zog
Hydrogen, tus naj npawb ib lub caij nyob rau hauv lub sij hawm lub sij hawm, muaj tsawg tshaj plaws ntawm cov protons, tsuas yog ib tug. Lub atom hydrogen kuj yog qhov tsawg tshaj plaws thiab lub teeb tshaj plaws ntawm tag nrho cov atoms. Hydrogen tshwm sim hauv ntiaj teb feem ntau hauv nws daim ntawv sib xyaw, qhov tseem ceeb tshaj plaws yog dej, uas yog cov khoom siv dav tshaj plaws hauv ntiaj teb.
Hydrogen muaj tus nqi combustion siab heev. Sib piv tus nqi ntawm cov cua sov uas tau muab tawm los ntawm kev hlawv tib lub zog ntawm cov roj av, roj av thiab hydrogen:
Nyob rau tib lub sijhawm,
Hlawv 1 gram ntawm natural gas, raws li kev ntsuas, txog 55.81 kilojoules ntawm tshav kub;
Hlawv 1 gram ntawm roj av muab tawm txog 48.4 kilojoules ntawm tshav kub;
Hlawv 1 gram ntawm hydrogen muab tawm txog 142.9 kilojoules ntawm tshav kub.
Hlawv hydrogen muab tawm 2.56 npaug ntawm cov cua kub ntau npaum li cov pa roj carbon monoxide thiab 2.95 npaug ntau dua li cov roj av. Nws tsis yog qhov nyuaj kom pom los ntawm cov ntaub ntawv no tias hydrogen muaj cov yam ntxwv ntawm cov roj zoo tagnrho - tus nqi hluav taws xob siab!
Hydrogen zog feem ntau yog nyob rau theem nrab zog, qhov tseem ceeb nyob rau hauv seb nws cov logic, technology thiab kev lag luam muaj qhov tseem ceeb thiab tus nqi ntawm ecological tshuav nyiaj li cas, kev tswj hwm ib puag ncig thiab kev hloov pauv huab cua. Lub zog thib ob yog nyob rau nruab nrab ntawm kev sib txuas ntawm thawj lub zog thiab cov neeg siv lub zog, thiab tuaj yeem muab faib ua ob pawg: ib qho yog "txoj kev ua tau zoo", lwm qhov yog "lub zog uas muaj lub cev muaj zog". Tsis muaj qhov tsis ntseeg tias lub zog hluav taws xob yog qhov siv dav tshaj plaws "txoj kev ua tau zoo", thaum roj av, roj av thiab roj av yog qhov siv dav tshaj plaws "lub zog hluav taws xob".
Los ntawm lub ntsiab lus ntawm kev xav, txij li "cov txheej txheem kev ua tau zoo" yog qhov nyuaj rau kev khaws cia ncaj qha rau hauv cov khoom loj, cov tsheb thauj mus los niaj hnub uas muaj zog txav, xws li tsheb, nkoj thiab dav hlau, tsis tuaj yeem siv hluav taws xob ntau los ntawm cov chaw tsim hluav taws xob. Hloov chaw, lawv tsuas tuaj yeem siv ntau qhov "lub zog muaj zog" xws li roj av, diesel, aviation kerosene thiab liquefied natural gas.
Txawm li cas los xij, kev lig kev cai yuav tsis tas mus li, thiab kev lig kev cai yuav tsis yog ib qho laj thawj. Nrog rau kev nce thiab kev loj hlob ntawm lub tsheb fais fab thiab hybrid hluav taws xob tsheb, "cov txheej txheem kev ua tau zoo" tuaj yeem hloov "lub zog muaj zog". Raws li cov laj thawj xav tau, nrog rau kev noj cov pob txha tas li, cov peev txheej thaum kawg yuav tas mus li, thiab "lub zog muaj zog" tshiab yuav tshwm sim, ntawm cov hydrogen zog yog tus sawv cev tseem ceeb.
Hydrogen muaj ntau nyob rau hauv cov xwm txheej, ua rau kwv yees li 75 feem pua ntawm cov huab hwm coj ntawm lub ntiaj teb. Nws yog dav nyob rau hauv huab cua, dej, fossil fuels thiab txhua hom carbohydrates.
Hydrogen muaj kev ua tau zoo combustion, siab ignition point, dav combustible ntau, thiab ceev combustion ceev. Los ntawm qhov kev xav ntawm tus nqi calorific thiab combustion, hydrogen yog twv yuav raug hu ua lub zog zoo thiab muaj txiaj ntsig zoo. Tsis tas li ntawd, hydrogen nws tus kheej yog non-toxic. Ntxiv rau kev tsim cov dej thiab ib qho me me ntawm hydrogen nitride tom qab combustion, nws yuav tsis tsim cov pa phem rau ecology thiab ib puag ncig, thiab tsis muaj carbon dioxide emissions. Yog li ntawd, lub zog hydrogen belongs rau lub zog huv, uas yog qhov tseem ceeb rau kev tswj hwm ib puag ncig ecological thiab txo cov pa roj carbon dioxide.
2. Lub luag haujlwm ntawm hydrogen zog
Hydrogen zog muaj cov saw hlau loj loj uas suav nrog kev npaj hydrogen, khaws cia, kev thauj mus los thiab refueling, roj hlwb thiab daim ntawv thov davhlau ya nyob twg.
Hauv kev tsim hluav taws xob, lub zog hydrogen tuaj yeem siv rau kev tsim hluav taws xob huv kom sib npaug ntawm lub zog xav tau thiab daws qhov tsis txaus ntawm lub zog hluav taws xob thaum lub sij hawm ncov.
Hauv cov cua sov, lub zog hydrogen tuaj yeem sib xyaw nrog cov pa roj carbon monoxide, uas yog ib qho ntawm ob peb lub zog hluav taws xob tsawg uas tuaj yeem sib tw nrog cov roj ntuj yav tom ntej.
Hauv kev lag luam aviation, uas tso tawm ntau dua 900 lab tons ntawm carbon dioxide txhua xyoo, hydrogen zog yog txoj hauv kev tseem ceeb los tsim cov pa roj carbon tsawg.
Nyob rau hauv cov tub rog teb, hydrogen roj cell yuav siv tau nyob rau hauv cov tub rog teb muaj qhov zoo ntawm kev nyob ntsiag to, muaj peev xwm ua tau tsis tu ncua tam sim no, siab zog hloov dua siab tshiab, yog ib qho tseem ceeb ntawm submarine stealth.
Hydrogen zog tsheb, hydrogen zog tsheb muaj zoo combustion kev ua tau zoo, ceev ignition, siab calorific nqi, ntau reserves thiab lwm yam zoo. Hydrogen zog muaj ntau qhov chaw thiab kev siv, uas tuaj yeem txo qhov kev faib ua feem ntawm fossil zog.
Kev txhim kho qib ntawm kev huv huv thiab txhim kho lub zog hydrogen yog ib qho tseem ceeb rau kev tsim kom muaj "ntau lub zog ntxiv" cov khoom siv hluav taws xob, thiab lub zog tsav tsheb loj rau kev hloov pauv thiab hloov kho dua tshiab.
