Txawm hais tias raws li lub caij nyoog cia lub zog los yog cov lus cog tseg zoo ntawm xoom-emission aviation, hydrogen tau ntev tau pom tias yog ib qho tseem ceeb ntawm kev siv tshuab rau carbon neutrality. Nyob rau tib lub sijhawm, hydrogen twb yog ib yam khoom tseem ceeb rau kev lag luam tshuaj, uas tam sim no yog cov neeg siv khoom loj tshaj plaws ntawm hydrogen hauv lub teb chaws Yelemees. Hauv 2021, German tshuaj nroj tsuag tau noj 1.1 lab tons ntawm hydrogen, uas yog sib npaug rau 37 terawatt teev ntawm lub zog thiab li ob feem peb ntawm hydrogen siv hauv lub teb chaws Yelemees.

Raws li kev tshawb fawb los ntawm German Hydrogen Task Force, qhov kev thov rau hydrogen hauv kev lag luam chemical tuaj yeem nce mus rau ntau dua 220 TWH ua ntej lub hom phiaj tsim carbon neutrality tiav hauv 2045. Pab pawg tshawb fawb, tsim los ntawm cov kws tshaj lij los ntawm Society for Chemical Engineering. thiab Biotechnology (DECHEMA) thiab National Academy of Science thiab Engineering (acatech), tau ua haujlwm los tsim ib txoj hauv kev los tsim kev lag luam hydrogen kom cov lag luam, kev tswj hwm, thiab kev nom kev tswv tuaj yeem sib koom ua ke nkag siab txog kev cia siab yav tom ntej ntawm kev lag luam hydrogen thiab kev lag luam. cov kauj ruam tsim nyog los tsim ib qho. Qhov project tau txais nyiaj pab ntawm € 4.25 lab los ntawm kev siv nyiaj ntawm German Ministry of Education thiab Research thiab German Ministry of Economic Affairs thiab Kev Nyab Xeeb Kev Nyab Xeeb. Ib qho ntawm cov cheeb tsam them los ntawm qhov project yog kev lag luam tshuaj (tsis suav cov refineries), uas tso tawm txog 112 metric tons ntawm carbon dioxide sib npaug hauv ib xyoos. Qhov ntawd suav txog kwv yees li 15 feem pua ​​​​ntawm lub teb chaws Yelemees tag nrho cov emissions, txawm hais tias cov sector tso nyiaj tsuas yog li 7 feem pua ​​​​ntawm tag nrho cov kev siv hluav taws xob.

Qhov pom tseeb tsis sib haum xeeb ntawm kev siv hluav taws xob thiab emissions hauv kev lag luam tshuaj yog vim kev lag luam siv fossil fuels los ua cov khoom siv hauv paus. Kev lag luam tshuaj tsis yog tsuas yog siv cov thee, roj, thiab cov nkev roj los ua lub zog, tab sis kuj rhuav tshem cov peev txheej no raws li cov khoom noj rau hauv cov khoom, feem ntau carbon thiab hydrogen, thiaj li yuav rov ua dua los tsim cov khoom siv tshuaj. Qhov no yog li cas kev lag luam tsim cov ntaub ntawv yooj yim xws li ammonia thiab methanol, uas tom qab ntawd ua tiav rau hauv cov yas thiab cov khoom siv dag zog, cov chiv thiab cov xim, cov khoom siv tu cev, tshuaj ntxuav tes thiab tshuaj. Tag nrho cov khoom no muaj cov fossil fuels, thiab qee qhov tseem muaj cov fossil fuels tag nrho, nrog rau kev kub nyhiab lossis siv cov pa roj tsev cog khoom suav nrog ib nrab ntawm kev lag luam emissions, nrog rau lwm qhov ib nrab los ntawm cov txheej txheem hloov dua siab tshiab.

Green hydrogen yog tus yuam sij rau kev lag luam tshuaj lom neeg ruaj khov

Yog li ntawd, txawm tias kev lag luam tshuaj lom neeg lub zog tuaj yeem los ntawm qhov chaw ruaj khov, nws tsuas yog ib nrab emissions. Kev lag luam tshuaj muaj peev xwm ntau tshaj li ib nrab ntawm nws cov emissions los ntawm kev hloov ntawm fossil (grey) hydrogen mus rau sustainable (ntsuab) hydrogen. Txog niaj hnub no, hydrogen tau tsim yuav luag tsuas yog los ntawm fossil fuels. Lub teb chaws Yelemees, uas tau txais txog 5% ntawm nws cov hydrogen los ntawm cov khoom siv txuas ntxiv, yog tus thawj coj thoob ntiaj teb. Los ntawm 2045/2050, lub teb chaws Yelemees qhov kev thov hydrogen yuav nce ntau tshaj li rau lub hlis mus rau ntau dua 220 TWH. Peak thov tuaj yeem siab txog 283 TWH, sib npaug rau 7.5 npaug ntawm kev noj tam sim no.
