Nyob rau xyoo tas los no, lub zog hydrogen tau rov tshwm sim ua ib qho tseem ceeb hauv kev lag luam tshiab. Kev lag luam hydrogen tau raug teev tseg meej meej tias yog ib qho ntawm cov lag luam tseem ceeb rau kev txhim kho, nrog rau cov khoom siv tshiab thiab cov tshuaj tshiab. Cov ntawv ceeb toom hais txog qhov xav tau los txhawb cov cav tshiab, suav nrog kev tsim khoom siv bio, kev lag luam aerospace, thiab kev lag luam qis, thaum tseem ceeb rau kev ua kom nrawm ntawm kev txhim kho kev lag luam hydrogen thawj zaug. Qhov no qhia txog lub peev xwm loj ntawm lub zog hydrogen.
Tam sim no, kev tsim cov hydrogen los ntawm thee yog cov qauv kev muab khoom, suav txog 64%, ua raws li cov khoom lag luam hydrogen (21%), cov roj av hydrogen (14%), thiab lwm txoj kev (1%). Qhov no qhia tau hais tias kev tsim cov roj fossil hydrogen tuav qhov tseem ceeb ntawm 99%, thaum electrolysis-based "green hydrogen" thiab lwm txoj kev tseem nyob qis. Yog li ntawd, cov chaw nres tsheb hydrogen tam sim no feem ntau siv cov qauv tsim khoom-khaws-kev thauj mus los hauv qab no: Cov tuam txhab Petrochemical hauv thaj chaw deb tsim cov hydrogen los ntawm cov roj fossil, compress cov hydrogen qis-siab (feem ntau ~ 1.5MPa) rau ~ 20MPa siv cov compressors, thiab khaws cia rau hauv 22MPa raj trailers. Cov hydrogen tom qab ntawd raug thauj mus rau cov chaw nres tsheb refueling, qhov twg nws dhau los ntawm kev nias theem ob mus rau 45MPa rau cov tsheb roj cell. Tus qauv sib cais no ua rau cov nqi thauj mus los, cov nqi khoom siv, thiab kev siv sijhawm ntau ntxiv, thaum tseem raug txwv los ntawm cov roj fossil-dependent "grey hydrogen" kev tsim khoom.
Ntxiv mus, raws li cov cai tam sim no, hydrogen raug cais ua cov tshuaj lom neeg uas yooj yim hlawv thiab tawg. Yog li ntawd, cov haujlwm tsim hydrogen feem ntau yog nyob rau hauv cov chaw ua tshuaj lom neeg nyob deb nroog nrog kev nyab xeeb thiab kev cai ib puag ncig nruj.
Nrog kev nce qib ntawm thev naus laus zis electrolysis, tus nqi tsim cov hydrogen ntsuab maj mam txo qis. Tib lub sijhawm, cov cai ib puag ncig xws li "carbon peaking thiab carbon neutrality" tab tom tsav cov hydrogen ntsuab kom dhau los ua qhov kev taw qhia tseem ceeb rau kev txhim kho lub zog roj yav tom ntej. Lub Koom Haum Zog Thoob Ntiaj Teb kwv yees tias los ntawm xyoo 2030, cov thev naus laus zis hydrogen qis carbon xws li electrolysis yuav suav txog 14% ntawm kev lag luam hydrogen, cuam tshuam loj heev rau cov qauv chaw nres tsheb roj. Kev tsim khoom raws li Electrolysis, nrog nws cov khoom noj yooj yim thiab nkag tau, ua rau muaj hydrogen ntau dua li cov chaw ua tshuaj lom neeg ib txwm muaj. Kev nias ncaj qha ntawm cov hydrogen tsim tawm hauv qhov chaw rau kev ntxiv roj rau tsheb tshem tawm kev thauj mus los ntev thiab kev nias thib ob, txo cov nqi kev lag luam thiab lub sijhawm.
Yuav kom hloov mus rau cov roj fossil uas siv hydrogen ua cov khoom siv tseem ceeb, ob hom diaphragm compressors tam sim no tswj hwm kev ua lag luam: 1) Cov chav sau Hydrogen nrog ~ 1.5MPa lub siab nqus thiab 20-22MPa lub siab tso tawm; 2) Cov chaw nres tsheb roj compressors nrog 5-20MPa lub siab nqus thiab 45MPa lub siab tso tawm. Txawm li cas los xij, cov txheej txheem ob theem no yuav tsum tau ua haujlwm sib koom tes ntawm ob chav. Ntxiv mus, thaum lub tog raj kheej khaws hydrogen lub siab poob qis dua 5MPa, cov compressors roj yuav tsis ua haujlwm, ua rau cov nqi siv hydrogen tsawg.
Nyob rau hauv kev sib piv, cov chaw tsim khoom hydrogen thiab chaw ntxiv roj ua ke qhia tau tias muaj kev ua haujlwm zoo dua. Hauv tus qauv no, hydrogen los ntawm electrolysis tuaj yeem raug nias ncaj qha los ntawm ~ 1.5MPa txog 45MPa siv ib lub tshuab compressor diaphragm, txo cov khoom siv thiab lub sijhawm siv. Qhov qis dua ntawm qhov siab nkag (1.5MPa vs. 5MPa) kuj tseem txhim kho kev siv hydrogen.
Thaum cov thev naus laus zis electrolysis nce qib, cov chaw nres tsheb hydrogen sib xyaw ua ke yuav tau txais kev siv dav dua, ua rau kev xav tau ntawm kev ua lag luam rau 1.5MPa-rau-45MPa diaphragm compressors. Peb lub tuam txhab muaj kev tsim qauv thiab kev tsim khoom dav dav los muab cov kev daws teeb meem rau qhov xwm txheej no. Nrog rau kev loj hlob ntawm kev tsim cov hydrogen ntsuab, cov chaw nres tsheb sib xyaw ua ke yuav nthuav dav, nthuav dav ob qho tib si kev siv ntawm diaphragm compressors thiab peb cov khoom lag luam thaum xa cov kev daws teeb meem tshiab.
Txawm li cas los xij, tseem muaj teeb meem hauv kev tsim cov chaw tsim hydrogen thiab cov compressors cuam tshuam, suav nrog cov nqi electrolysis siab, kev faib tawm cov tshuaj lom neeg txaus ntshai ntawm hydrogen, thiab cov khoom siv hydrogen tsis tiav. Kev daws cov teeb meem no kom zoo yuav tseem ceeb rau kev txhim kho cov kab ke zog hydrogen.
