Nokuba kukugcinwa kwamandla onyaka okanye isithembiso esikhulu sokungakhuphi umbane emoyeni, i-hydrogen ibisoloko ibonwa njengendlela yetekhnoloji ebalulekileyo yokungakhethi cala kwekhabhoni. Kwangaxeshanye, i-hydrogen sele iyimveliso ebalulekileyo kwishishini leekhemikhali, elisebenzisa kakhulu i-hydrogen eJamani ngoku. Ngo-2021, izityalo zeekhemikhali zaseJamani zisebenzise iitoni ze-hydrogen ezizigidi ezili-1.1, ezilingana neeyure ezingama-37 ze-terawatt zamandla kunye ne-hydrogen esetyenziswa eJamani malunga nesibini kwisithathu.

Ngokutsho kophando olwenziwe yiGerman Hydrogen Task Force, imfuno yehydrogen kwishishini leekhemikhali inokunyuka iye kwi-220 TWH ngaphambi kokuba kufikelelwe kumgomo wokungathathi cala kwekhabhoni ngo-2045. Iqela lophando, eliqulunqwe ziingcali ezivela kwiSociety for Chemical Engineering and Biotechnology (DECHEMA) kunye neNational Academy of Science and Engineering (acatech), lanikwa umsebenzi wokuyila imephu yendlela yokwakha uqoqosho lwe-hydrogen ukuze amashishini, ulawulo, kunye nabadlali bezopolitiko bakwazi ukuqonda kunye amathuba anokubakho exesha elizayo oqoqosho lwe-hydrogen kunye namanyathelo afunekayo ukuze kwenziwe olunye. Le projekthi ifumene inkxaso-mali ye-€4.25 yezigidi kwisabelo-mali seSebe leMfundo noPhando laseJamani kunye neSebe leMicimbi yezoQoqosho kunye neNtshukumo yeMozulu laseJamani. Enye yeendawo ezigutyungelwe yile projekthi lishishini leekhemikhali (ngaphandle kweendawo zokucocisa), elikhupha malunga neetoni ezili-112 ze-carbon dioxide ezilingana ngonyaka. Oko kwenza malunga ne-15 ekhulwini yegesi iyonke ekhutshwa eJamani, nangona eli candelo libanga malunga ne-7 ekhulwini kuphela yemveliso iyonke esetyenziswayo.

Ukungafani okubonakalayo phakathi kokusetyenziswa kwamandla kunye nokukhutshwa kwegesi kwicandelo leekhemikhali kungenxa yokusebenzisa kweshishini amafutha efosili njengezinto ezisisiseko. Ishishini leekhemikhali alisebenzisi nje kuphela amalahle, ioyile, kunye negesi yendalo njengemithombo yamandla, kodwa likwahlukanisa ezi zixhobo njengezondlo zibe zizinto, ngokuyintloko ikhabhoni kunye nehydrogen, ukuze ziphinde zidityaniswe ukuvelisa iimveliso zeekhemikhali. Le yindlela eli shishini elivelisa ngayo izinto ezisisiseko ezifana ne-ammonia kunye ne-methanol, ezithi emva koko zicutshungulwe zibe ziiplastiki kunye neeresini zokwenziwa, izichumisi kunye neepeyinti, iimveliso zococeko lomntu, izicoci kunye namayeza. Zonke ezi mveliso ziqulethe amafutha efosili, kwaye ezinye zenziwe ngamafutha efosili kuphela, apho ukutshisa okanye ukutsha kweegesi zegreenhouse kubanga isiqingatha sokukhutshwa kwegesi kushishino, kwaye esinye isiqingatha sivela kwinkqubo yokuguqula.

I-hydrogen eluhlaza sisitshixo soshishino lweekhemikhali oluzinzileyo

Ngoko ke, nokuba amandla eshishini leekhemikhali avela kwimithombo ezinzileyo, aya kunciphisa kuphela ukukhutshwa kwegesi ngesiqingatha. Ishishini leekhemikhali linokunciphisa ukukhutshwa kwegesi ngesiqingatha ngaphezulu kokutshintsha ukusuka kwi-hydrogen yefossil (grey) ukuya kwi-hydrogen ezinzileyo (green). Ukuza kuthi ga ngoku, i-hydrogen iveliswe phantse kuphela kwi-fossil fuels. IJamani, efumana malunga ne-5% ye-hydrogen yayo kwimithombo evuselelekayo, ikhokela kwihlabathi liphela. Ngowama-2045/2050, imfuno ye-hydrogen yaseJamani iya kunyuka ngokuphindwe kathandathu ukuya ngaphezulu kwe-220 TWH. Imfuno ephakame kakhulu inokuba phezulu njenge-283 TWH, elingana ne-7.5 yezihlandlo zokusetyenziswa kwangoku.
