Nokuba njengogcino lwamandla onyaka okanye isithembiso esikhulu sokuhamba ngenqwelomoya kungabikho kukhutshwa, i-hydrogen kudala ibonwa njengeyona ndlela ifunekayo yetekhnoloji yokungathathi hlangothi kwekhabhoni. Kwangaxeshanye, ihydrogen sele iyinto ebalulekileyo kwishishini lemichiza, engoyena msebenzisi mkhulu wehydrogen eJamani. Ngo-2021, izityalo zekhemikhali zaseJamani zasebenzisa i-1.1 yezigidi zeetoni ze-hydrogen, ezilingana neeyure ezingama-37 ze-terawatt zamandla kunye nesibini kwisithathu se-hydrogen esetyenziswa eJamani.

Ngokophononongo olwenziwa yiJamani i-Hydrogen Task Force, imfuno ye-hydrogen kwishishini lemichiza inokunyuka ibe ngaphezu kwe-220 TWH ngaphambi kokuba i-carbon neutrality target iphunyezwe ngo-2045. Iqela lophando, eliqulunqwe ziingcali ezivela kwi-Society for Chemical Engineering. kunye neBiotechnology (DECHEMA) kunye neNational Academy of Science and Engineering (acatech), yanikwa umsebenzi wokuyila imephu yendlela yokwakha uqoqosho lwe-hydrogen ukuze abezoshishino, ulawulo, kunye nabadlali bezopolitiko bakwazi ukuqonda ngokudibeneyo amathemba anokubakho kwikamva loqoqosho lwe-hydrogen kunye amanyathelo afunekayo ukwenza enye. Le projekthi ifumene inkxaso-mali ye-€ 4.25 yezigidi kuhlahlo lwabiwo-mali lwe-Ofisi yoMphathiswa weMfundo noPhando lwaseJamani kunye noMphathiswa wezoQoqosho kunye neZenzo zeMozulu zaseJamani. Enye yemimandla equkwa yile projekthi lishishini lemichiza (kungabandakanywa iindawo zokucoca), elikhupha malunga ne-112 yeetoni zemetriki zekharbon diokside elinganayo ngonyaka. Oko kuthetha malunga ne-15 ekhulwini lezinto ezikhutshwa eJamani zizonke, nangona eli candelo lithatha kuphela isi-7 ekhulwini sombane osetyenziswayo.

Ukungafani okubonakalayo phakathi kosetyenziso lwamandla kunye nokukhutshwayo kwicandelo lemichiza kungenxa yosetyenziso lweshishini lwamafutha efosili njengesiseko semathiriyeli. Ushishino lweekhemikhali alusebenzisi nje kuphela amalahle, i-oyile, kunye negesi yendalo njengemithombo yamandla, kodwa kwakhona iphula ezi zixhobo njengempahla yokutya ibe yizinto, ngokuyinhloko i-carbon kunye ne-hydrogen, ukuze iphinde idityaniswe ukuvelisa iimveliso zeekhemikhali. Yile ndlela ishishini livelisa ngayo izinto ezisisiseko ezifana ne-ammonia kunye ne-methanol, ezithi ke ziphinde zicutshungulwe zibe yiplastiki kunye neentlaka ezenziweyo, izichumisi kunye neepeyinti, iimveliso zococeko lomntu, izicoci kunye namayeza. Zonke ezi mveliso ziqulathe amafutha efosili, kwaye ezinye zide zenziwe ngokupheleleyo ngamafutha efosili, ngokutshisa okanye ukutya iigesi zegreenhouse ezibalelwa kwisiqingatha sezinto ezikhutshwayo kushishino, esinye isiqingatha sivela kwinkqubo yokuguqula.

I-hydrogen eluhlaza ngundoqo kwishishini lemichiza elizinzileyo

Ngoko ke, nokuba amandla oshishino lweekhemikhali aphuma ngokupheleleyo kwimithombo ezinzileyo, anokukunciphisa ngesiqingatha ukukhutshwa kwezinto ezikhutshwayo. Ushishino lweekhemikhali lunokuba ngaphezu kwesiqingatha ukukhutshwa kwalo ngokutshintsha kwifosili (ngwevu) yehydrogen ukuya ezinzileyo (eluhlaza) ihydrogen. Ukuza kuthi ga ngoku, ihydrogen sele iveliswe phantse ngokukodwa kumafutha efosili. IJamani, efumana malunga ne-5% ye-hydrogen yayo kwimithombo evuselelekayo, yinkokeli yamazwe ngamazwe. Ngo-2045/2050, imfuno yehydrogen yaseJamani iya kunyuka ngokuphindwe kathandathu ukuya ngaphezulu kwe-220 TWH. Imfuno ephezulu inokuba phezulu njenge-283 TWH, ilingana ne-7.5 amaxesha okusetyenziswa ngoku.
