Kungakhathaliseki ukuthi njengesitoreji samandla sesizini noma isithembiso esihle sokundiza okungakhiphi, i-hydrogen kudala ibonwa njengendlela yobuchwepheshe ebaluleke kakhulu ekungathathi hlangothi kwekhabhoni. Ngesikhathi esifanayo, i-hydrogen isivele iyimpahla ebalulekile embonini yamakhemikhali, okwamanje engumsebenzisi omkhulu we-hydrogen eJalimane. Ngo-2021, izitshalo zamakhemikhali zaseJalimane zadla amathani ayizigidi ezingu-1.1 e-hydrogen, okulingana namahora angama-terawatt angu-37 kanye nezingxenye ezimbili kwezintathu ze-hydrogen esetshenziswa eJalimane.

Ngokocwaningo olwenziwe yi-German Hydrogen Task Force, isidingo se-hydrogen embonini yamakhemikhali singakhuphukela ngaphezu kuka-220 TWH ngaphambi kokuba okuhlosiwe okuhlosiwe kokungathathi hlangothi kwekhabhoni kufinyelelwe ngo-2045. Ithimba labacwaningi, elakhiwe ochwepheshe beNhlangano Yezobunjiniyela Bamakhemikhali. kanye ne-Biotechnology (DECHEMA) kanye ne-National Academy of Science and Engineering (i-acatech), yanikezwa umsebenzi wokuklama umgwaqo wokwakha umnotho we-hydrogen ukuze amabhizinisi, ezokuphatha, nabalingisi bezombusazwe bakwazi ukuqonda ngokuhlanganyela amathuba esikhathi esizayo omnotho we-hydrogen kanye izinyathelo ezidingekayo ukuze udale eyodwa. Le phrojekthi ithole uxhaso lwama-euro ayizigidi ezingu-4.25 kusabelomali soMnyango Wezemfundo Nocwaningo waseJalimane kanye noMnyango Wezindaba Zomnotho kanye Nesenzo Sesimo Sezulu waseJalimane. Enye yezindawo ezikhona kulo mklamo imboni yamakhemikhali (ngaphandle kwezindawo zokuhlanza), ekhipha amathani angama-metric angu-112 alingana nesikhutha ngonyaka. Lokho kubala cishe amaphesenti angu-15 engqikithi yokukhishwa kwegesi yaseJalimane, nakuba lo mkhakha uthatha amaphesenti angaba ngu-7 kuphela engqikithi yamandla asetshenziswayo.

Ukungafani okusobala phakathi kokusetshenziswa kwamandla kanye nesisi esikhishwayo emkhakheni wamakhemikhali kungenxa yokusebenzisa kwemboni izibaseli ezimbiwa phansi njengesisekelo sezinto. Imboni yamakhemikhali ayisebenzisi nje kuphela amalahle, uwoyela, negesi yemvelo njengemithombo yamandla, kodwa futhi idiliza lezi zinsiza njengokuphakelayo zibe izakhi, ikakhulukazi ikhabhoni ne-hydrogen, ukuze zihlanganiswe kabusha ukuze kukhiqizwe imikhiqizo yamakhemikhali. Lena yindlela imboni ekhiqiza ngayo izinto eziyisisekelo ezifana ne-ammonia ne-methanol, ezibuye zicutshungulwe zibe amapulasitiki nezinsalela zokwenziwa, umanyolo nopende, imikhiqizo yenhlanzeko yomuntu siqu, izinto zokuhlanza kanye nemithi. Yonke le mikhiqizo iqukethe izinto zokubasa ezimbiwa phansi, futhi ezinye zenziwa ngisho nangezibaseli ezimbiwa phansi, lapho ukushisa noma ukusetshenziswa kwamagesi abamba ukushisa okuyingxenye yokukhishwa kwemboni, kanti enye ingxenye iphuma ohlelweni lokuguqula.

I-hydrogen eluhlaza iyisihluthulelo semboni yamakhemikhali esimeme

Ngakho-ke, ngisho noma amandla emboni yamakhemikhali avela ngokuphelele emithonjeni eqhubekayo, ayenganciphisa ukukhishwa kwegesi ngesigamu kuphela. Imboni yamakhemikhali inganciphisa ngaphezu kwesigamu ukukhishwa kwayo ngokushintsha i-hydrogen (grey) hydrogen iye esimeme (eluhlaza) i-hydrogen. Kuze kube manje, i-hydrogen iye yakhiqizwa cishe kuphela ngamafutha ezinto ezimbiwa phansi. I-Germany, ethola cishe u-5% we-hydrogen yayo emithonjeni evuselelekayo, ingumholi wamazwe ngamazwe. Ngo-2045/2050, isidingo se-hydrogen saseJalimane sizokwenyuka ngaphezu kokuphindwe kasithupha siye ngaphezu kwama-220 TWH. Isidingo esiphezulu singafinyelela ku-283 TWH, okulingana nezikhathi ezingu-7.5 zokusetshenziswa kwamanje.
