Raws li lub zog ruaj khov thiab kev lag luam qis qis tau nce ntxiv, kev txaus siab rau hydrogen raws li lub zog huv si txuas ntxiv mus ntxiv. Hydrogen tuaj yeem tsim los ntawm ntau txoj hauv kev, suav nrog ntsuab hydrogen, grey hydrogen, xiav hydrogen, daj hydrogen, dawb hydrogen, thiab xim av hydrogen. Tsab ntawv xov xwm no yog txhawm rau tshawb nrhiav cov kev faib tawm sib txawv ntawm kev tsim cov hydrogen thiab lawv cov kev cuam tshuam ib puag ncig.
Brown Hydrogen:
Brown hydrogen yog tsim los ntawm hlawv thee los tsim hydrogen. Txij li cov thee yog cov roj carbon fossil roj, cov xim av hydrogen ua rau cov pa roj carbon emissions tseem ceeb, ua rau muaj kev cuam tshuam ib puag ncig.
Grey Hydrogen:
Grey hydrogen yog txoj kev siv ntau tshaj plaws ntawm hydrogen ntau lawm, tso siab rau cov txheej txheem fossil roj xws li chav methane hloov pauv thiab thee gasification. Hmoov tsis zoo, cov txheej txheem grey hydrogen ntau lawm ua rau muaj cov pa roj carbon dioxide emissions, uas muaj kev cuam tshuam rau ib puag ncig.
Blue Hydrogen:
Blue hydrogen sawv cev rau txoj hauv kev hloov pauv kom txo qis carbon emissions hauv grey hydrogen ntau lawm. Zoo ib yam li grey hydrogen, xiav hydrogen yog tsim los siv cov txheej txheem roj fossil, tab sis nws suav nrog carbon capture thiab cia (CCS) technologies los txo cov pa roj carbon dioxide. Blue hydrogen ua ib qho kev daws teeb meem rau cov pa roj carbon emission txo, tab sis nws tseem cia siab rau cov khoom siv roj fossil.
Ntsuab Hydrogen:
Green hydrogen yog tsim los ntawm dej electrolysis siv lub zog tauj dua tshiab xws li hnub ci, cua, thiab hluav taws xob hluav taws xob. Txoj kev no ua rau tsis muaj cov pa roj carbon dioxide emissions, ua rau nws yog txoj hauv kev zoo tshaj plaws rau kev tsim cov hydrogen. Kev txhawb nqa thiab kev txais yuav ntawm ntsuab hydrogen tuaj yeem ua rau cov pa roj carbon emission txo thiab txo kev hloov pauv huab cua.
Yellow Hydrogen:
Yellow hydrogen yog tsim los ntawm harnessing nuclear zog, los ntawm nuclear fission los yog fusion, los tsim hydrogen. Nuclear zog, raws li lub zog huv thiab ruaj khov, ua rau cov khoom siv daj hydrogen nrog qis lossis xoom carbon emissions.
Dawb Hydrogen:
Dawb hydrogen yog tsim los ntawm cov txheej txheem roj fossil, xws li chav methane hloov kho, tab sis nrog kev koom ua ke ntawm carbon capture thiab cia (CCS) technologies los txo cov pa roj carbon monoxide. Dawb hydrogen nthuav tawm qis carbon emissions piv rau grey hydrogen, tab sis nws tseem cia siab rau cov khoom siv roj fossil.
Nyob rau hauv cov ntsiab lus, ntsuab hydrogen yog suav hais tias yog ib tug tshaj plaws ib puag ncig tus phooj ywg thiab sustainable ntau lawm txoj kev, siv lub zog tauj dua tshiab yam tsis muaj generating carbon emissions. Blue hydrogen ua ib qho kev hloov pauv hloov pauv los txo cov pa roj carbon monoxide, thaum grey hydrogen, daj hydrogen, dawb hydrogen, thiab xim av hydrogen nthuav tawm txawv qhov cuam tshuam ib puag ncig nyob ntawm seb lub zog siv thiab cov khoom siv hluav taws xob ua haujlwm.
Xaiv txoj kev tsim cov hydrogen tsim nyog yog qhov tseem ceeb rau kev tsav tsheb hloov pauv hloov hluav taws xob thiab txo qis carbon emissions. Nrog rau kev siv thev naus laus zis thiab kev txhawb nqa txoj cai, kev cia siab rau kev txhim kho ntawm ntsuab hydrogen thiab xiav hydrogen tau cog lus tseg, ua rau muaj txiaj ntsig zoo rau kev ua tiav cov hom phiaj huab cua thiab hloov pauv lub zog. Ib txhij, txo kev cia siab rau grey hydrogen, thiab nce kev nqis peev thiab kev tshawb fawb hauv cov pa roj carbon tsawg xws li ntsuab hydrogen thiab xiav hydrogen, yuav pab txhawb kev loj hlob ntawm kev lag luam hydrogen thiab tsim lub hauv paus rau lub zog huv si yav tom ntej.
