Hydrogen, ntau yam khoom siv hluav taws xob, tau lees paub ntau ntxiv rau nws lub luag haujlwm hauv kev hloov mus rau lub zog muaj zog yav tom ntej. Ob txoj hauv kev tseem ceeb rau kev lag luam hydrogen yog los ntawm cov pa roj carbon monoxide thiab methanol. Txhua txoj hauv kev muaj nws qhov tshwj xeeb zoo thiab cov nyom, uas qhia txog kev hloov pauv tsis tu ncua hauv cov thev naus laus zis thev naus laus zis.
Natural Gas Hydrogen Production (steam reforming process)
Natural gas, feem ntau yog tsim los ntawm methane, yog cov khoom noj ntau tshaj plaws rau hydrogen ntau lawm thoob ntiaj teb. Cov txheej txheem, hu uachav methane hloov kho(SMR), suav nrog reacting methane nrog chav ntawm qhov kub thiab txias los tsim hydrogen thiab carbon dioxide. Txoj kev no yog nyiam rau nws cov kev ua tau zoo thiab scalability, ua rau nws lub caj qaum ntawm cov khoom siv hydrogen.
Txawm hais tias nws muaj kev tswj hwm, kev cia siab rau cov pa roj carbon monoxide ua rau muaj kev txhawj xeeb txog cov pa roj carbon emissions. Txawm li cas los xij, kev nce qib hauv carbon capture thiab khaws cia (CCS) thev naus laus zis tau koom ua ke los txo cov kev cuam tshuam ib puag ncig. Tsis tas li ntawd, kev tshawb nrhiav kev siv cov cua sov los ntawm nuclear reactors los txhim kho hydrogen ntau lawm yog lwm qhov kev tshawb fawb uas tuaj yeem txo qis cov pa roj carbon monoxide ntawm cov pa roj hydrogen ntau lawm.
Methanol Hydrogen Production (chav hloov kho ntawm methanol)
Methanol, ntau yam tshuaj tau los ntawm cov pa roj lossis biomass, muaj lwm txoj hauv kev rau hydrogen ntau lawm. Cov txheej txheem koom nrogmethanol chav hloov pauv(MSR), qhov twg methanol reacts nrog chav los tsim hydrogen thiab carbon dioxide. Txoj kev no tau txais kev saib xyuas vim nws lub peev xwm rau kev ua haujlwm siab dua thiab qis dua cov pa roj carbon emissions piv rau kev hloov pauv cov pa roj.
Methanol qhov kom zoo dua yog nyob rau hauv nws qhov yooj yim ntawm kev cia thiab thauj, uas yog yooj yim dua li hydrogen. Cov yam ntxwv no ua rau nws muaj kev xaiv txaus nyiam rau kev tsim cov khoom siv hydrogen decentralized, uas yuav txo tau qhov kev xav tau ntawm kev tsim kho vaj tse. Ntxiv mus, kev koom ua ke ntawm methanol ntau lawm nrog cov khoom siv hluav taws xob txuas ntxiv, xws li cua thiab hnub ci, tuaj yeem txhim kho nws cov txiaj ntsig ib puag ncig.
Kev sib piv
Ob qho tib si natural gas thiab methanolhydrogen ntau lawmtxoj kev muaj lawv qhov zoo thiab kev txwv. Cov pa roj carbon monoxide tam sim no yog txoj hauv kev zoo tshaj plaws thiab siv tau zoo, tab sis nws cov pa roj carbon monoxide tseem yog ib qho kev txhawj xeeb tseem ceeb. Methanol, thaum muab cov khoom siv huv dua, tseem nyob rau theem pib ntawm kev txhim kho thiab ntsib cov teeb meem hauv kev nthuav tawm ntau lawm.
Qhov kev xaiv ntawm cov txheej txheem no nyob ntawm ntau yam, suav nrog kev muaj cov khoom noj khoom haus, kev xav txog ib puag ncig, thiab kev nce qib thev naus laus zis. Raws li lub ntiaj teb txav mus rau lub neej yav tom ntej ntawm lub zog muaj zog dua, kev txhim kho ntawm cov tshuab hybrid uas sib xyaw ua ke ntawm ob txoj hauv kev tuaj yeem yog ib qho kev cog lus.
Xaus
Lub evolution tsis tu ncua nyob rau hauvhydrogen daws(hydrogen ntau lawm cog) qhia txog qhov tseem ceeb ntawm kev sib txawv ntawm cov khoom siv hluav taws xob thiab kev sib koom ua ke cov kev daws teeb meem tshiab. Natural gas thiab methanol hydrogen ntau lawm sawv cev rau ob txoj hauv kev tseem ceeb uas, thaum ua kom zoo thiab sib xyaw ua ke, tuaj yeem ua rau muaj txiaj ntsig zoo rau kev hloov pauv hluav taws xob thoob ntiaj teb. Raws li kev tshawb fawb thiab kev txhim kho txuas ntxiv mus, cov txheej txheem no yuav hloov zuj zus ntxiv, ua txoj hauv kev rau kev lag luam hydrogen kom ruaj khov.
