Nyob rau hauv xyoo tas los no, hydrogen zog tau rov tshwm sim los ua ib lub ntsiab lus tseem ceeb hauv lub zog tshiab. Kev lag luam hydrogen tau qhia meej meej tias yog ib qho ntawm cov kev lag luam tseem ceeb ntawm kev tsim kho tshiab, nrog rau cov khoom lag luam xws li cov ntaub ntawv tshiab thiab cov tshuaj tshiab. Cov ntawv ceeb toom hais txog qhov yuav tsum tau ua kom muaj kev loj hlob tshiab, suav nrog bio-tsim, kev lag luam aerospace, thiab kev lag luam qis qis, thaum qhia meej meej qhov tseem ceeb ntawm kev nrawm ntawm hydrogen kev lag luam kev loj hlob thawj zaug. Qhov no underscores lub peev xwm loj ntawm hydrogen zog.
Tam sim no, thee-based hydrogen ntau lawm dominates cov qauv khoom, suav txog 64%, ua raws li kev lag luam los ntawm cov khoom siv hydrogen (21%), natural gas-based hydrogen (14%), thiab lwm txoj kev (1%). Qhov no qhia tau hais tias fossil roj-raws li hydrogen ntau lawm tuav ib tug kiag li dominance ntawm 99%, thaum electrolysis-raws li "ntsuab hydrogen" thiab lwm txoj kev nyob rau hauv marginal. Yog li ntawd, tam sim no hydrogen refueling chaw nres tsheb feem ntau txais yuav cov nram qab no ntau lawm-storage-transportation qauv: Petrochemical tuam txhab uas muag nyob rau hauv tej thaj chaw deb tsim hydrogen los ntawm fossil fuels, compress low-pressure hydrogen (feem ntau ~ 1.5MPa) rau ~ 20MPa siv compressors, thiab khaws cia rau hauv 22MPa raj trailer. Tom qab ntawd cov hydrogen raug thauj mus rau cov chaw nres tsheb refueling, qhov twg nws nkag mus rau theem nrab compression mus rau 45MPa rau roj tsheb tsheb. Cov qauv sib cais no ua rau nce nqi tsheb thauj mus los, cov khoom siv, thiab kev siv sijhawm, thaum tseem muaj kev txwv los ntawm fossil fuel-dependant "grey hydrogen" ntau lawm.
Tsis tas li ntawd, nyob rau hauv cov kev cai tam sim no, hydrogen raug cais raws li cov khoom siv hluav taws xob thiab cov tshuaj lom neeg tawg. Yog li ntawd, hydrogen ntau lawm tej yaam num yog feem ntau concentrated nyob rau hauv tej thaj chaw deb chemical chaw ua si nrog nruj kev ruaj ntseg thiab ib puag ncig yuav tsum tau.
Nrog rau kev siv thev naus laus zis thev naus laus zis, cov nqi tsim khoom ntawm ntsuab hydrogen yog maj mam txo. Nyob rau tib lub sijhawm, ib puag ncig cov cai xws li "cov pa roj carbon peaking thiab carbon neutrality" yog tsav cov hydrogen ntsuab los ua ib qho kev taw qhia tseem ceeb rau kev txhim kho lub zog roj av yav tom ntej. Lub koom haum International Energy tau kwv yees tias los ntawm 2030, low-carbon hydrogen technologies like electrolysis will account for 14% of the hydrogen market, significantly influencing refueling stations layouts. Electrolysis-raws li kev tsim khoom, nrog nws cov khoom siv yooj yim thiab siv tau, ua kom muaj hydrogen ntau dua li cov chaw ua si tshuaj. Ncaj qha compression ntawm on-site tsim hydrogen rau lub tsheb refueling tshem tawm cov tsheb thauj mus los mus ntev thiab compression thib ob, zoo txo nqi nyiaj txiag thiab lub sij hawm.
Txhawm rau hloov mus rau lub hauv paus fossil roj-raws li hydrogen mov saw, ob hom diaphragm compressors tam sim no ua lag luam: 1) Hydrogen filling units nrog ~ 1.5MPa kom siab thiab 20-22MPa tawm siab; 2) Refueling chaw nres tsheb compressors nrog 5-20MPa kom txaus siab thiab 45MPa tawm siab. Txawm li cas los xij, cov txheej txheem ob-theem no yuav tsum muaj kev sib koom tes ntawm ob chav nyob. Ntxiv mus, thaum hydrogen cia lub tog raj kheej siab poob qis dua 5MPa, cov refueling compressors ua haujlwm tsis tau, ua rau cov nqi siv hydrogen tsawg.
Nyob rau hauv sib piv, integrated hydrogen ntau lawm-refueling stations qhia superior efficiency. Hauv cov qauv no, hydrogen los ntawm electrolysis tuaj yeem ncaj qha los ntawm ~ 1.5MPa rau 45MPa siv ib lub diaphragm compressor, txo cov khoom siv thiab cov nqi sijhawm. Qhov qis qis qis qis qis (1.5MPa vs. 5MPa) kuj tseem txhim kho kev siv hydrogen.
Raws li kev siv thev naus laus zis thev naus laus zis, kev sib xyaw ua ke hydrogen chaw yuav tsum tau txais kev pom dav dua, tsav kev lag luam xav tau rau 1.5MPa-to-45MPa diaphragm compressors. Peb lub tuam txhab muaj kev tsim qauv thiab tsim muaj peev xwm los muab cov kev daws teeb meem rau daim ntawv thov no. Nrog rau kev loj hlob feem ntau ntawm ntsuab hydrogen ntau lawm, integrated chaw nres tsheb yog npaj rau proliferate, nthuav ob daim ntawv thov prospects ntawm diaphragm compressors thiab peb cov khoom portfolio thaum xa cov tshiab refueling daws.
Txawm li cas los xij, cov teeb meem tseem muaj nyob rau hauv kev tsim cov chaw nres tsheb hydrogen thiab cov compressors txuam nrog, nrog rau cov nqi hluav taws xob siab, hydrogen cov tshuaj lom neeg muaj kev phom sij, thiab tsis tiav hydrogen infrastructure. Kev daws cov teeb meem zoo no yuav yog qhov tseem ceeb rau kev nce qib kev siv hluav taws xob hydrogen.
