Amafemu amabili asebenzise i-hydrogen ukusebenzisa i-hydrogen ukushisa insimbi esikhungweni esiseSweden, okuyisinyathelo esingagcina sisize ukwenza le mboni ibe nokusimama.
Ngasekuqaleni kwaleli sonto i-Ovako, egxile ekwenzeni uhlobo oluthile lwensimbi olubizwa nge-engineering yensimbi, ithe ibibambisene neLinde Gas kuphrojekthi eseHofors rolling mill.
Ekulingweni, i-hydrogen isetshenziswe njengophethiloli ukukhiqiza ukushisa esikhundleni segesi kaphethiloli. U-Ovako wayefuna ukugqamisa inzuzo yezemvelo yokusebenzisa i-hydrogen enqubweni yomlilo, eqaphela ukuthi okuwukuphela kwento ekhiqizwayo kwakuwumphunga wamanzi.
"Lokhu kuyintuthuko enkulu embonini yensimbi," kusho uGöran Nyström, oyisekela likamongameli omkhulu ka-Ovako kwezokukhangisa ngamaqembu nobuchwepheshe, esitatimendeni.
"Kungokokuqala ukuthi i-hydrogen isetshenziselwe ukushisa insimbi endaweni ekhona yokukhiqiza," engeza.
"Ngenxa yokuqulwa kwecala, siyazi ukuthi i-hydrogen ingasetshenziswa kalula futhi kalula, kungabi namthelela ekhwalithi yensimbi, okungasho ukwehliswa okukhulu kwekhabhoni."
Njengemikhakha eminingi yezimboni, imboni yensimbi inomthelela omkhulu emvelweni. Ngokwe-World Steel Association, ngokwesilinganiso, kukhishwe amathani ayi-1.85 e-carbon dioxide ngethani ngalinye lensimbi ekhiqizwe ngo-2018. I-International Energy Agency ichaze umkhakha wensimbi "njengothembele kakhulu emalahleni, ahlinzeka ngama-75% ukufunwa kwamandla. ”
Uphethiloli wesikhathi esizayo?
I-European Commission ichaze i-hydrogen njengomthwali wamandla “anamandla amakhulu okuthola amandla ahlanzekile, asebenzayo ezinhlelweni ezimile, eziphathekayo nezokuthutha.”
Yize i-hydrogen ngokungangabazeki inamandla, kunezinselelo ezithile uma kuziwa ekukhiqizeni.
Njengoba uMnyango Wezamandla wase-US uphawulile, i-hydrogen ngokuvamile “ayiziveli ngokwayo emvelweni” futhi idinga ukwenziwa ngamakhemikhali ayiqukethe.
Imithombo eminingi - kusuka kumafutha wezinsalela nelanga, kuya ekuphefumuleni komhlaba - ingaveza i-hydrogen. Uma kusetshenziswa imithombo evuselelekayo ekukhiqizweni kwayo, ibizwa nge- “green hydrogen.”
Ngenkathi izindleko zisakhathaza, eminyakeni embalwa edlule kubonakale i-hydrogen isetshenziswa ezindaweni eziningi zokuhamba njengezitimela, izimoto namabhasi.
Esibonelweni sakamuva samafemu amakhulu ezokuthutha athatha izinyathelo zokucindezela ubuchwepheshe bangene kakhulu, iVolvo Group neDaimler Truck muva nje bamemezele izinhlelo zokubambisana ezigxile kubuchwepheshe be-hydrogen fuel-cell.
La mafemu amabili athi asungule ibhizinisi elihlanganyelwe elingu-50/50, ebheke “ukuthuthukisa, ukukhiqiza nokuthengisa amasistimu amaseli kaphethiloli ngezicelo zezimoto ezinzima namanye amacala okusetshenziswa.”
