'Kev siv tsis raug cai ntawm hydrogen' tuaj yeem ua rau lub zog hloov pauv qeeb: Qhia

Kev siv Hydrogen los ntawm G-7 tuaj yeem dhia los ntawm plaub mus rau xya npaug los ntawm nruab nrab ntawm lub xyoo pua no piv rau xyoo 2020 txhawm rau "ua kom txaus siab rau qhov kev xav tau ntawm lub tshuab hluav taws xob xoom xoom," raws li tsab ntawv ceeb toom tshiab los ntawm Lub Chaw Haujlwm Saib Xyuas Kev Siv Hluav Taws Xob Thoob Ntiaj Teb. .

Hauv tsab ntawv tshaj tawm rau tsab ntawv tshaj tawm, IRENA Tus Thawj Coj-General Francesco La Camera tau hais tias nws tau "ua kom pom tseeb tias hydrogen yuav tsum ua lub luag haujlwm tseem ceeb hauv kev hloov pauv hluav taws xob yog tias lub ntiaj teb yuav ua raws 1.5 ° C lub hom phiaj ntawm Paris Daim Ntawv Pom Zoo. "

Txawm hais tias qhov kev lees paub no, IRENA qhov kev tshuaj xyuas - uas tau tshaj tawm rau hnub Wednesday, thaum lub rooj sib tham COP27 huab cua hloov pauv hauv tebchaws Iziv - pleev xim rau tag nrho cov duab uas yuav xav tau kom muaj kev sib npaug zoo mus tom ntej.

Ntawm lwm yam, nws tau sau tseg tias "txawm hais tias hydrogen lub peev xwm loj, nws yuav tsum nco ntsoov tias nws cov khoom tsim, kev thauj mus los thiab kev hloov pauv yuav tsum muaj zog, nrog rau kev nqis peev tseem ceeb."

"Kev siv tsis raug cai ntawm hydrogen tuaj yeem ua rau qeeb zog hloov pauv," nws hais ntxiv. "Qhov no hu rau qhov tseem ceeb hauv kev tsim txoj cai."

Thawj qhov tseem ceeb ntawm cov haujlwm no, IRENA tau hais tias, muaj feem xyuam rau kev decarbonization ntawm "cov ntawv thov hydrogen uas twb muaj lawm." Qhov thib ob yog nyob ib ncig ntawm kev siv hydrogen hauv "kev siv nyuaj-rau-abate" xws li aviation, steel, shipping thiab tshuaj.

Kev hloov pauv ntawm lub zog tuaj yeem pom dav dav raws li kev hloov pauv ntawm cov fossil fuels mus rau lub kaw lus tswj hwm los ntawm kev rov ua dua tshiab. Muab hais tias nws nyob ntawm ntau yam - los ntawm thev naus laus zis thiab nyiaj txiag mus rau kev koom tes thoob ntiaj teb - yuav ua li cas txoj kev hloov pauv mus rau qhov tseem yuav pom.

Ib tus kws tshaj lij rau Hydrogen Europe, lub koom haum kev lag luam, hais rau CNBC tias IRENA yog "yog tias kev xa tawm ntawm cov txheej txheem loj thiab kev tsim hluav taws xob xav tau kev nqis peev loj, thiab nws muaj tseeb tias nws xav tau lub zog los tsim, khaws cia thiab thauj hydrogen. ”

Tus cev lus tau hais tias Hydrogen Europe tau pom zoo "txhua qhov kev txhim kho ntawm hydrogen-txog cov haujlwm yuav tsum tau ua lub luag haujlwm thiab qee qhov kev siv yuav tsum tau ua ntej tshaj lwm tus."

"Raws li yuav ua li cas ua ntej, peb ntseeg tias qhov no yuav tsum ua kom ntau li ntau tau los ntawm kev lag luam cov cuab yeej uas muaj txiaj ntsig zoo rau CO2 emissions txuag thiab lwm yam (xws li kev ruaj ntseg ntawm kev muab khoom), kom cov neeg siv khoom tuaj yeem txiav txim siab xaiv," lawv ntxiv.

Lawv tau hais tias "kev txwv sab saum toj-down dogmatic ntawm qee qhov haujlwm," xws li hydrogen rau cua sov, yuav tsum zam, lawv tau hais.

Cia siab rau hydrogen

Piav qhia los ntawm Lub Chaw Haujlwm Saib Xyuas Hluav Taws Xob Thoob Ntiaj Teb raws li "cov khoom siv hluav taws xob ntau yam," hydrogen muaj ntau hom kev siv thiab tuaj yeem xa mus rau ntau yam kev lag luam.

Nws tuaj yeem tsim nyob rau hauv ntau txoj kev. Ib txoj hauv kev suav nrog electrolysis, nrog cov hluav taws xob tam sim no faib dej rau hauv oxygen thiab hydrogen.

Yog hais tias cov hluav taws xob siv nyob rau hauv cov txheej txheem no los ntawm ib tug tauj dua tshiab qhov chaw xws li cua los yog hnub ci ces ib txhia hu nws "ntsuab" los yog "renewable" hydrogen. Niaj hnub no, feem ntau ntawm hydrogen tiam yog raws li fossil fuels.

Hauv tsab ntawv tshaj tawm nrog rau nws daim ntawv tshaj tawm, IRENA tau hais tias G-7 lub hom phiaj ntawm net-zero emissions los ntawm nruab nrab ntawm lub xyoo pua no yuav "yuav tsum muaj kev xa tawm tseem ceeb ntawm ntsuab hydrogen."

Ob peb xyoos dhau los no, kev lag luam loj thiab kev lag luam tau saib mus rau hauv kev lag luam ntsuab hydrogen nyob rau hauv kev sib tw los decarbonize txoj kev lag luam tseem ceeb rau lub neej niaj hnub ua haujlwm.

Thaum lub rooj sib tham rooj sib tham ntawm COP27 lub lim tiam dhau los, Tus Thawj Kav Tebchaws German Olaf Scholz tau piav qhia txog ntsuab hydrogen yog "ib qho ntawm cov thev naus laus zis tseem ceeb tshaj plaws rau lub ntiaj teb huab cua tsis zoo."

"Green hydrogen yog tus yuam sij rau decarbonizing peb cov kev lag luam, tshwj xeeb tshaj yog rau cov khoom siv hluav taws xob nyuaj xws li kev tsim steel, kev lag luam tshuaj, kev thauj khoom hnyav thiab dav hlau," Scholz ntxiv, ua ntej lees paub tias yuav tsum muaj kev ua haujlwm tseem ceeb rau cov haujlwm. kom loj hlob.

"Tau kawg, ntsuab hydrogen tseem yog kev lag luam me me, nws cov kev tsim khoom yog tam sim no kim heev piv rau fossil fuels," nws hais.

"Tseem muaj 'tus qaib thiab qe' qhov teeb meem ntawm kev xa khoom thiab kev thov uas cov neeg ua lag luam thaiv ib leeg, tos lwm tus txav mus."

Tsis tas li ntawd tshwm sim ntawm lub vaj huam sib luag yog Christian Bruch, CEO ntawm Zog Siemens. "Hydrogen yuav yog qhov tseem ceeb rau decarbonization ntawm ... kev lag luam," nws hais.

"Cov lus nug yog, rau peb tam sim no, yuav ua li cas peb tuaj yeem muaj nyob hauv lub ntiaj teb uas tseem tau tsav, hais txog kev lag luam, los ntawm hydrocarbons," nws hais ntxiv. "Yog li nws yuav tsum tau siv zog ntxiv los ua cov phiaj xwm ntsuab hydrogen ... ua haujlwm."
