Hauv cov ntsiab lus dav dav, hydrogen tuaj yeem siv los ua roj hauv ob txoj hauv kev tseem ceeb. Nws tuaj yeem raug hlawv los ua cua sov, lossis nws tuaj yeem muab tso rau hauv cov roj hluav taws xob hydrogen los tsim hluav taws xob. Qhov xwm zoo yog tias ib zaug xiav lossis ntsuab hydrogen tau tsim, nws muaj ntau yam kev siv sib txawv:
Kev thauj mus los:Hydrogen twb tau siv los roj tsheb npav thiab lwm yam kev thauj mus los rau pej xeem, tshwj xeeb hauv Nyiv. Nws tseem tuaj yeem siv rau lub zog thauj cov tsheb thauj khoom thiab tsheb ciav hlau, thaum cov roj hydrogen-based xws li ammonia tuaj yeem siv rau hauv aviation thiab shipping. Kev siv hydrogen ntau dua rau lub zog tsheb yuav nyob ntawm tus nqi ntawm cov roj hluav taws xob hydrogen ua pheej yig dua thiab cov chaw nres tsheb hydrogen ua ntau dua.

Kev tsim hluav taws xob:Hydrogen tuaj yeem siv los hloov lub zog txuas ntxiv mus rau hauv cov roj uas tuaj yeem khaws cia thiab thauj mus ntev. Hydrogen thiab ammonia kuj tuaj yeem siv rau hauv cov roj turbines thiab cov chaw siv hluav taws xob hluav taws xob los txo lawv cov emissions.

Cov tsev cua sov:Hydrogen muaj peev xwm loj heev los hloov cov nkev roj rau cua sov hauv tsev thiab kev lag luam ntawm cov khoom siv hluav taws xob uas twb muaj lawm. Hydrogen boilers thiab domestic hydrogen roj hlwb xav tau kev txhim kho ntxiv tab sis tuaj yeem ua lub luag haujlwm tseem ceeb rau yav tom ntej.

Kev lag luam:Hydrogen yog tam sim no siv nyob rau hauv ntau yam ntawm cov txheej txheem tseem ceeb. Cov no muaj xws li refining petrol, manufacturing steel, kho hlau thiab ua ntau yam tshuaj.

Tsis zoo li grey hydrogen, ntsuab hydrogen yog tag nrho txuas ntxiv nyob rau hauv ob qho tib si nws cov khoom siv thiab nws lub zog mov. Rau cov khoom siv, ntsuab hydrogen niaj hnub no feem ntau yog tsim los ntawm dej los ntawm cov txheej txheem hu ua electrolysis, uas siv cov hluav taws xob tam sim no los faib dej rau hauv nws cov molecules ntawm hydrogen thiab oxygen. Qhov no yog ua los ntawm cov khoom siv hu ua electrolyzer, uas siv lub cathode thiab anode (zoo thiab tsis zoo electrodes). Cov txheej txheem no tsuas yog tsim cov pa oxygen - lossis chav - raws li cov khoom lag luam. Raws li kev siv hluav taws xob, kom tsim nyog raws li "ntsuab hydrogen," lub hauv paus ntawm hluav taws xob siv rau electrolysis yuav tsum tau los ntawm lub zog tauj dua tshiab, xws li cua lossis hnub ci zog.

Muaj peb yam tseem ceeb ntawm electrolyzers:Alkaline, proton exchange membrane (PEM), thiab khoom oxide. Cov no sib txawv ntawm cov khoom siv electrolyte siv. Alkaline electrolyzers siv cov tshuaj aqueous nrog cov ntsev zoo li alkaline kom ua tau hluav taws xob, thaum PEM electrolyzers siv cov khoom polymer membrane (electrolyte). Cov khoom siv oxide electrolyzers siv cov khoom siv ceramic ua cov electrolyte, uas ua rau lawv ua haujlwm ntawm hluav taws xob ntau dua thiab kub ntau dua. Qhov no tso cai rau kev siv cov ncu thiab cua sov sab nraud los ua qhov chaw siv hluav taws xob ntau dua li kev cia siab rau hluav taws xob. Yog li, cov khoom siv oxide electrolysis ua rau txo qis nqi ntawm kev ua haujlwm, txij li thaum tshav kub feem ntau tsis tshua kim thiab qee zaum ib txwm ua los ntawm cov khoom lag luam ntawm qee yam kev lag luam.

Ntau xyoo dhau los, hydrogen tau pom tsuas yog kev daws teeb meem rau kev hloov pauv ntawm cov tsheb ntsuab. Raws li lub tsheb hluav taws xob tau txais kev sib tw ntau dua, hydrogen tau pom ntau dua los ua kev daws teeb meem rau lwm qhov kev lag luam.

Qhov kev thov rau hydrogen tseem nce ntxiv raws li nws cov kev siv nthuav dav thoob plaws hauv kev lag luam thiab kev tsim khoom lag luam rau ntau lub hom phiaj, suav nrog roj refining, steelmaking thiab cement ntau lawm. Txawm li cas los xij, raws li hydrogen lub koob meej loj hlob tuaj, qhov tseem ceeb ntawm ntsuab hydrogen tsis tuaj yeem hais ntau dhau. Alarmingly, 98% ntawm hydrogen yog tsim los ntawm fossil fuels uas tsis muaj carbon dioxide emissions tswj los yog kev cai nyob rau hauv qhov chaw. Tab sis ntsuab hydrogen muaj peev xwm hloov qhov ntawd - kom zoo.

Los ntawm kev lag luam cog cov pa luam yeeb mus rau roj av thiab diesel-powered tsheb pa fumes, ntsuab hydrogen ntau lawm txo los yog tshem tawm qhov xav tau rau fossil roj zog qhov chaw uas tso tawm ntau cov pa roj carbon dioxide rau hauv cov huab cua. Hauv kev lag luam hauv cov ntaub ntawv, raws li cov txheej txheem khaws cia tsim hydrogen, nws tuaj yeem siv los hloov cov tshuab hluav taws xob diesel-powered backup energize yav tom ntej cov ntaub ntawv chaw. Raws li qhov tshwm sim, cov txiaj ntsig ntsuab hydrogen muaj ntau, tso cai rau tsoomfwv thiab cov koom haum los txhawb lub teb chaws lub zog kev ruaj ntseg, txuag roj, txo tag nrho cov emissions thiab diversify lub zog kev thauj mus los ntawm cov tsheb mus rau expansive pej xeem systems.

Green hydrogen thev naus laus zis tsis tuaj yeem qhia lub sijhawm zoo dua. Lub US Energy Information Administration kwv yees hais tias lub ntiaj teb no lub zog xav tau yuav nce 47% los ntawm 2050. Tib txoj kev los offset qhov kev thov nyob rau hauv daim ntawv ntawm cov roj thiab thee zog tsim yog los ntawm kev siv cov greener txoj kev, xws li ntsuab hydrogen.

Thiab ua tsaug rau cov txheej txheem thev naus laus zis uas muaj qhov tseem ceeb decarbonized tsim cov hydrogen, ntau lub tuam txhab tau tig mus rau carbon offsets uas leverage ntsuab hydrogen kom txo tau lawv cov pa roj carbon hneev taw thiab ua tau raws li ESG cov hom phiaj.

Cov txheej txheem ntawm kev tsim ntsuab hydrogen los nrog qhov zoo. Lub koom haum International Energy Agency (IEA) hais tias ntsuab hydrogen txuag kwv yees li 830 lab tons ntawm cov pa roj carbon dioxide tawm txhua xyoo piv rau thaum cov roj tau tsim siv cov txheej txheem roj fossil. Qhov ntawd yog sib npaug rau tag nrho lub xyoo tsim nyog ntawm emissions los ntawm UK thiab Indonesia ua ke!

Ib yam li nrog cov thev naus laus zis tshiab, muaj qee qhov kev sib tw kom kov yeej raws li cov ntsuab hydrogen boom tuav. Qee qhov teeb meem xav txog suav nrog cov txheej txheem kev ua tau zoo thiab cov nqi tsim khoom ntawm qhov loj, ntxiv rau kev tsim cov kev daws teeb meem rau lub sijhawm ntev. Kev sib tw ib sab, ntsuab hydrogen yog qhov zoo siab tshiab thev naus laus zis uas tuaj yeem pab sib npaug ntawm qhov xav tau ntau qhov loj ntawm kev tsim hluav taws xob ntsuab.

Ib feem loj ntawm kev hloov pauv ntawm cov roj fossil suav nrog kev siv hluav taws xob rau qee lub tshuab niaj hnub peb siv uas yog siv los ntawm roj thiab roj - tsheb thiab tsheb thauj mus los hauv zos, thiab cua sov rau tsev hauv qee lub tebchaws, piv txwv li. Rau cov uas twb muaj hluav taws xob lawm, xws li khoos phis tawj thiab khoom siv hauv tsev, hluav taws xob los ntawm nuclear thiab txuas ntxiv dua tshiab xws li cua thiab hnub ci hloov cov thee.

Tab sis muaj qee qhov kev lag luam uas xav tau ntau lub zog uas ib txwm siv dua tshiab tuaj yeem ua tsis tau raws li lawv qhov kev thov. Qhov ntawd yog ib qho teeb meem, vim hais tias cov kev lag luam yog cov saum toj kawg nkaus emitters ntawm tsev xog paj.

Qhov no yog qhov uas cov kws tshaj lij hais tias ntsuab hydrogen muaj peev xwm loj heev.

International Energy Agency.

"Hydrogen muaj ntau yam txaus los sau qee qhov qhov tsis txaus ntseeg no - hauv kev muab cov khoom noj tseem ceeb rau cov tshuaj thiab cov lag luam hlau lossis cov khoom xyaw tseem ceeb rau cov roj carbon tsawg rau cov dav hlau thiab nkoj," Remme hais rau CNN.

Kev ua haujlwm ntawm lub dav hlau lossis lub nkoj loj, piv txwv li, yuav tsum muaj lub zog ntau heev uas txhua lub roj teeb uas siv los khaws hluav taws xob los ntawm hnub ci lossis cua yuav zoo li loj thiab hnyav rau lub nkoj. Ntsuab hydrogen, ntawm qhov tod tes, tuaj yeem ua kua thiab sib dua. Raws li Airbus, uas tab tom tsim lub dav hlau ua lag luam zero-emissions, lub zog ntom ntom ntawm ntsuab hydrogen yog peb npaug ntau dua li cov dav hlau uas peb siv niaj hnub no.

Thaum cov kua ntsuab hydrogen yuav emit xoom carbon, nws muaj qee qhov kev txwv. Thaum hlawv nyob rau hauv qhov chaw qhib nws tso ib tug me me ntawm nitrous oxide, uas yog ib tug muaj zog tsev cog khoom roj. Txawm li cas los xij, yog tias hydrogen tau noj los ntawm cov roj cell, nws tsuas yog tawm dej thiab cua sov xwb.

Qee lub dav hlau me me tau tswj hwm ya nrog cov roj hydrogen-fed, txawm tias cov thev naus laus zis tseem tsis tau nce mus rau kev lag luam.

Tam sim no nws yog tag nrho cov tes ntawm lub lawj kom ua tiav cov hom phiaj huab cua. Lub zog hloov pauv xav tau kev txhawb nqa loj. Hydrogen tuaj yeem ua qhov tseem ceeb rau qhov no. Kev sib koom tes yog qhov tseem ceeb txhawm rau kom muaj peev xwm siv hydrogen ua tiav, piv txwv li, txhawm rau pab txo qis CO2 hauv kev lag luam, e-fuels rau dav hlau thiab siv nyob rau hauv ib puag ncig tsim. Tab sis kev nqis peev yog xav tau thiab muaj lus nug.
