Txawm yog kev khaws cia lub zog rau lub caij lossis kev cog lus zoo ntawm kev ya dav hlau uas tsis muaj pa phem, hydrogen tau ntev los lawm pom tias yog txoj hauv kev tseem ceeb rau kev tsis muaj pa roj carbon. Tib lub sijhawm, hydrogen twb yog ib yam khoom tseem ceeb rau kev lag luam tshuaj lom neeg, uas tam sim no yog tus neeg siv hydrogen ntau tshaj plaws hauv lub tebchaws Yelemees. Xyoo 2021, cov chaw tsim tshuaj lom neeg hauv tebchaws Yelemees tau siv 1.1 lab tons ntawm hydrogen, uas sib npaug rau 37 terawatt teev ntawm lub zog thiab kwv yees li ob feem peb ntawm cov hydrogen siv hauv lub tebchaws Yelemees.

Raws li kev tshawb fawb los ntawm German Hydrogen Task Force, qhov kev thov rau hydrogen hauv kev lag luam tshuaj lom neeg tuaj yeem nce mus txog ntau dua 220 TWH ua ntej lub hom phiaj carbon neutrality tau tsim tsa hauv xyoo 2045. Pab pawg tshawb fawb, uas muaj cov kws tshaj lij los ntawm Society for Chemical Engineering and Biotechnology (DECHEMA) thiab National Academy of Science and Engineering (acatech), tau raug xaiv los tsim daim ntawv qhia kev rau kev tsim kom muaj kev lag luam hydrogen kom cov lag luam, kev tswj hwm, thiab cov neeg ua haujlwm nom tswv tuaj yeem nkag siab txog yav tom ntej ntawm kev lag luam hydrogen thiab cov kauj ruam uas xav tau los tsim ib qho. Qhov project tau txais kev pab nyiaj ntawm € 4.25 lab los ntawm cov peev nyiaj ntawm German Ministry of Education thiab Research thiab German Ministry of Economic Affairs thiab Climate Action. Ib qho ntawm cov cheeb tsam uas tau them los ntawm qhov project yog kev lag luam tshuaj lom neeg (tsis suav nrog cov chaw ua roj), uas tso tawm txog li 112 metric tons ntawm carbon dioxide sib npaug hauv ib xyoos. Qhov ntawd suav txog li 15 feem pua ​​​​​​ntawm tag nrho cov pa phem ntawm lub teb chaws Yelemees, txawm hais tias lub sector tsuas yog suav txog li 7 feem pua ​​​​​​ntawm tag nrho cov kev siv zog.

Qhov tsis sib xws ntawm kev siv zog thiab cov pa phem hauv cov tshuaj lom neeg yog vim kev lag luam siv roj av ua cov khoom siv tseem ceeb. Kev lag luam tshuaj lom neeg tsis yog siv thee, roj, thiab roj av ua cov khoom siv zog xwb, tab sis kuj rhuav cov peev txheej no ua cov khoom noj khoom haus, feem ntau yog carbon thiab hydrogen, kom rov sib xyaw ua ke los tsim cov khoom siv tshuaj lom neeg. Qhov no yog li cas kev lag luam tsim cov khoom siv yooj yim xws li ammonia thiab methanol, uas tom qab ntawd raug ua tiav ntxiv rau hauv cov yas thiab cov resins dag, chiv thiab xim, cov khoom siv tu cev tus kheej, cov tshuaj ntxuav thiab tshuaj. Tag nrho cov khoom no muaj roj av, thiab qee qhov txawm tias muaj roj av tag nrho, nrog kev hlawv lossis noj cov pa roj av uas suav nrog ib nrab ntawm kev lag luam cov pa phem, nrog rau ib nrab los ntawm cov txheej txheem hloov pauv.

Hydrogen ntsuab yog qhov tseem ceeb rau kev lag luam tshuaj lom neeg ruaj khov

Yog li ntawd, txawm tias lub zog ntawm kev lag luam tshuaj lom neeg los ntawm cov chaw ruaj khov tag nrho, nws tsuas yog yuav txo cov pa phem ib nrab xwb. Kev lag luam tshuaj lom neeg tuaj yeem txo nws cov pa phem ntau dua ib nrab los ntawm kev hloov ntawm cov roj av fossil (grey) mus rau cov roj av hydrogen ruaj khov (ntsuab). Txog niaj hnub no, hydrogen tau tsim tawm yuav luag txhua yam los ntawm cov roj fossil. Lub teb chaws Yelemees, uas tau txais kwv yees li 5% ntawm nws cov hydrogen los ntawm cov chaw rov ua dua tshiab, yog tus thawj coj thoob ntiaj teb. Los ntawm xyoo 2045/2050, Lub teb chaws Yelemees qhov kev thov hydrogen yuav nce ntau dua rau npaug rau ntau dua 220 TWH. Qhov kev thov siab tshaj plaws yuav siab txog 283 TWH, sib npaug rau 7.5 npaug ntawm kev siv tam sim no.
