Universal Hydrogen's hydrogen fuel cell demonstrator ua nws lub dav hlau dav hlau mus rau Moss Lake, Washington, lub lim tiam dhau los. Lub davhlau sim tau siv sijhawm 15 feeb thiab mus txog qhov siab ntawm 3,500 ko taw. Lub platform xeem yog raws li Dash8-300, lub ntiaj teb loj tshaj plaws hydrogen roj cell aircraft.
Lub dav hlau, lub npe hu ua Lightning McClean, tau tawm ntawm Grant County International Tshav Dav Hlau (KMWH) thaum 8:45 teev sawv ntxov lub Peb Hlis 2 thiab mus txog qhov siab ntawm 3,500 ko taw 15 feeb tom qab. Lub davhlau, raws li daim ntawv pov thawj FAA Tshwj Xeeb Airworthiness, yog thawj zaug ntawm ob xyoos kev sim davhlau uas xav tias yuav xaus rau xyoo 2025. Lub dav hlau, uas tau hloov los ntawm ATR 72 lub dav hlau hauv cheeb tsam, khaws cia tsuas yog ib qho qub fossil roj turbine cav. rau kev nyab xeeb, thaum tus so yog powered los ntawm ntshiab hydrogen.
Universal Hydrogen lub hom phiaj kom muaj lub davhlau ya nyob twg hauv cheeb tsam uas siv los ntawm hydrogen roj hlwb los ntawm 2025. Hauv qhov kev sim no, lub cav siv los ntawm cov roj ntsha uas huv huv hydrogen emissions tsuas yog dej thiab tsis ua phem rau cov huab cua. Vim nws yog qhov kev sim ua ntej, lwm lub cav tseem khiav ntawm cov pa roj. Yog li ntawd, yog tias koj saib nws, muaj qhov sib txawv loj ntawm sab laug thiab txoj cai cav, txawm tias txoj kab uas hla ntawm cov hniav thiab tus naj npawb ntawm cov hniav. Raws li Universal Hydrogren, cov dav hlau siv los ntawm cov roj hluav taws xob hydrogen muaj kev nyab xeeb dua, pheej yig dua rau kev khiav lag luam thiab tsis muaj kev cuam tshuam rau ib puag ncig. Lawv cov roj hluav taws xob hydrogen yog modular thiab tuaj yeem thauj khoom thiab thauj khoom los ntawm lub tshav dav hlau cov chaw thauj khoom uas twb muaj lawm, yog li lub tshav dav hlau tuaj yeem ua tau raws li cov kev xav tau ntawm hydrogen-powered aircraft yam tsis muaj kev hloov kho. Hauv txoj kev xav, dav hlau loj tuaj yeem ua tau zoo ib yam, nrog cov turbofans uas siv los ntawm hydrogen roj hlwb xav kom siv los ntawm nruab nrab-2030s.
Qhov tseeb, Paul Eremenko, co-founder thiab CEO ntawm Universal Hydrogen, ntseeg hais tias jetliners yuav tsum khiav ntawm hydrogen huv si nyob rau hauv nruab nrab-2030s, txwv tsis pub kev lag luam yuav tsum tau txiav flights kom tau raws li qhov yuav tsum tau ntawm kev lag luam emissions lub hom phiaj. Qhov tshwm sim yuav yog qhov nce nqi ntawm daim pib thiab kev tawm tsam kom tau daim pib. Yog li ntawd, nws yog ib qho tseem ceeb los txhawb kev tshawb fawb thiab kev loj hlob ntawm lub zog tshiab aircraft. Tab sis thawj lub davhlau no kuj muaj qee qhov kev cia siab rau kev lag luam.
Lub luag haujlwm tau ua los ntawm Alex Kroll, ib tus neeg paub txog yav dhau los US Air Force test pilot thiab lub tuam txhab tus thawj coj sim tsav. Nws tau hais tias nyob rau hauv qhov kev sim thib ob, nws muaj peev xwm ya tag nrho ntawm hydrogen roj cell generators, yam tsis muaj kev vam khom rau cov roj siv hluav taws xob qub. Kroll tau hais tias "Lub dav hlau hloov kho muaj kev ua haujlwm zoo heev thiab cov roj hluav taws xob hluav taws xob hluav taws xob ua rau muaj suab nrov thiab kev vibration tsis zoo dua li cov tshuab turbine ib txwm siv," Kroll hais.
Universal Hydrogen muaj ntau tus neeg caij tsheb xaj rau hydrogen-powered lub dav hlau hauv cheeb tsam, suav nrog Connect Airlines, ib lub tuam txhab Asmeskas. John Thomas, tus thawj coj ntawm lub tuam txhab, hu ua Lightning McClain's flight "ground zero for the decarbonization of the world aviation industry."
Vim li cas hydrogen-powered aircraft yog ib qho kev xaiv rau carbon txo nyob rau hauv aviation?
Kev hloov pauv huab cua ua rau huab cua thauj khoom muaj kev pheej hmoo rau ntau xyoo tom ntej.
Aviation emissions tsuas yog ib feem ntawm cov pa roj carbon dioxide ntau npaum li cov tsheb thiab tsheb thauj khoom, raws li World Resources Institute, ib pab pawg tshawb fawb tsis muaj txiaj ntsig nyob hauv Washington. Txawm li cas los xij, cov dav hlau nqa cov neeg caij tsheb tsawg dua ib hnub dua li tsheb thiab tsheb thauj khoom.
Plaub lub dav hlau loj tshaj plaws (Asmeskas, United, Delta thiab Southwest) tau nce lawv cov dav hlau siv dav hlau los ntawm 15 feem pua ntawm 2014 thiab 2019. Txawm li cas los xij, txawm tias lub dav hlau muaj txiaj ntsig ntau dua thiab cov pa roj carbon tsawg tau muab tso rau hauv kev tsim khoom, cov neeg caij tsheb tau nyob. kev poob qis txij li xyoo 2019.
Cov tuam txhab tau cog lus los ua cov pa roj carbon nruab nrab los ntawm ib nrab xyoo pua, thiab qee qhov tau nqis peev hauv cov roj hluav taws xob ruaj khov kom tso cai rau aviation los ua lub luag haujlwm tseem ceeb hauv kev hloov pauv huab cua.
Sustainable fuels (SAFs) yog biofuels ua los ntawm cov roj ua noj, tsiaj rog, pov tseg hauv nroog lossis lwm yam khoom noj. Cov roj tuaj yeem sib xyaw nrog cov pa roj rau lub zog dav hlau tshuab thiab twb tau siv rau hauv kev sim davhlau thiab txawm tias cov neeg caij tsheb tau teem sijhawm. Txawm li cas los xij, cov roj hluav taws xob ruaj khov yog kim, kwv yees li peb npaug ntau npaum li cov roj dav hlau. Raws li ntau lub dav hlau yuav thiab siv cov roj hluav taws xob ruaj khov, cov nqi yuav nce ntxiv. Cov neeg tawm tswv yim txhawb kom muaj kev txhawb siab xws li kev so se los txhawb kev tsim khoom.
Sustainable fuels tau pom tias yog cov roj txuas hluav taws xob uas tuaj yeem txiav cov pa roj carbon emissions kom txog thaum muaj kev cuam tshuam loj dua xws li hluav taws xob lossis hydrogen-powered aircraft tiav. Qhov tseeb, cov thev naus laus zis no yuav tsis siv dav hauv aviation rau lwm 20 lossis 30 xyoo.
Cov tuam txhab tab tom sim tsim thiab tsim lub dav hlau hluav taws xob, tab sis feem ntau yog cov dav hlau me me, zoo li lub dav hlau ya dav hlau uas tawm mus thiab tsaws vertically thiab tuav tsuas yog ib txhais tes ntawm cov neeg caij tsheb.
Ua lub dav hlau hluav taws xob loj uas muaj peev xwm nqa tau 200 tus neeg caij tsheb - qhov sib npaug ntawm lub dav hlau nruab nrab - yuav xav tau roj teeb loj dua thiab lub sijhawm ya davhlau ntev dua. Los ntawm tus qauv ntawd, cov roj teeb yuav tsum hnyav li 40 npaug ntau npaum li cov roj dav hlau kom them tag nrho. Tab sis cov dav hlau hluav taws xob yuav ua tsis tau yog tias tsis muaj kev hloov pauv hauv roj teeb thev naus laus zis.
Hydrogen zog yog ib qho cuab yeej siv tau zoo kom ua tiav cov pa roj carbon tsawg thiab ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv ntiaj teb lub zog hloov pauv. Qhov txiaj ntsig tseem ceeb ntawm hydrogen zog dua lwm qhov chaw hluav taws xob tauj dua tshiab yog tias nws tuaj yeem khaws cia rau ntawm qhov loj thoob plaws lub caij. Ntawm lawv, ntsuab hydrogen yog tib txoj kev sib sib zog nqus decarbonization hauv ntau qhov kev lag luam, suav nrog cov chaw lag luam uas sawv cev los ntawm petrochemical, hlau, tshuaj lom neeg kev lag luam thiab kev lag luam tsheb thauj mus los sawv cev los ntawm aviation. Raws li International Commission ntawm Hydrogen Energy, lub lag luam hydrogen zog yuav tsum ncav cuag $ 2.5 trillion los ntawm 2050.
"Hydrogen nws tus kheej yog roj teeb heev," Dan Rutherford, tus kws tshawb fawb txog tsheb thiab dav hlau decarbonization ntawm International Council on Clean Transportation, ib pab pawg neeg ib puag ncig, hais rau Associated Press. "Tab sis koj xav tau lub tank loj los khaws hydrogen, thiab lub tank nws tus kheej hnyav heev."
Tsis tas li ntawd, muaj qhov tsis zoo thiab teeb meem rau kev siv cov roj hydrogen. Piv txwv li, kev tsim kho tshiab loj thiab kim kim yuav xav tau ntawm tshav dav hlau los khaws cov roj hydrogen txias rau hauv cov kua dej.
Tseem, Rutherford tseem ceev faj txog qhov zoo ntawm hydrogen. Nws pab neeg ntseeg tias cov dav hlau siv hydrogen yuav tuaj yeem mus txog 2,100 mais los ntawm 2035.
