Ukuthuthukiswa “kwe-hydrogen eluhlaza” sekuyinto evunyelwene ngayo

Esikhungweni sokukhiqiza i-hydrogen ye-photovoltaic se-Baofeng Energy, amathangi amakhulu okugcina igesi abhalwe ukuthi “Green Hydrogen H2″ kanye ne-“Green Oxygen O2″ ami elangeni. Eshabhu, kuhlelwe ngendlela ehlelekile izihlukanisi ze-hydrogen eziningi kanye namadivayisi okuhlanza i-hydrogen. Izingcezu zamaphaneli okukhiqiza ugesi we-photovoltaic zifakwe ehlane.

UWang Jirong, inhloko yephrojekthi yamandla e-hydrogen ye-Baofeng Energy, utshele i-China Securities Journal ukuthi idivayisi yokuphehla amandla e-photovoltaic engama-kilowatt angu-200,000 yakhiwe ucezu lwamaphaneli okuphehla amandla e-photovoltaic, kanye nedivayisi yokuphehla i-hydrogen yamanzi e-electrolysed enamandla angama-cubic metres angu-20,000 e-hydrogen ngehora. Iphrojekthi Yemboni Yezimboni Ye-Feng Energy Hydrogen.

"Kusetshenziswa ugesi okhiqizwa yi-photovoltaics njengamandla, i-electrolyzer isetshenziselwa ukukhiqiza 'i-hydrogen eluhlaza' kanye 'nomoya-mpilo oluhlaza', okungena ohlelweni lokukhiqiza i-olefin lwe-Baofeng Energy ukuze kuthathelwe indawo amalahle esikhathini esidlule. Izindleko eziphelele zokukhiqiza 'i-hydrogen eluhlaza' zingama-yuan angu-0.7 kuphela/ UWang Jirong ubikezela ukuthi ama-electrolyzer angu-30 azosetshenziswa ngaphambi kokuphela kwephrojekthi. Ngemva kokuthi konke sekuqalile ukusebenza, angakhiqiza izikwele ezijwayelekile eziyizigidi ezingu-240 ze-"hydrogen eluhlaza" kanye nezikwele ezijwayelekile eziyizigidi ezingu-120 ze-"oxygen eluhlaza" minyaka yonke, kunciphisa ukusetshenziswa kwemithombo yamalahle cishe ngamathani angu-38 ngonyaka. Amathani ayi-10,000, kunciphisa ukukhishwa kwe-carbon dioxide ngamathani angaba ngu-660,000. Esikhathini esizayo, inkampani izothuthuka ngokuphelele ekukhiqizeni nasekugcineni i-hydrogen, ukugcina nokuthutha i-hydrogen, kanye nokwakhiwa kwesiteshi sokugcwalisa i-hydrogen, futhi yandise izimo zokusetshenziswa ngokubambisana nemigqa yamabhasi okubonisa amandla e-hydrogen edolobheni ukuze kufezwe ukuhlanganiswa kochungechunge lonke lwemboni yamandla e-hydrogen.

I-“Green Hydrogen” ibhekisela ku-hydrogen ekhiqizwa yi-electrolysis yamanzi ngogesi oguqulwe kusuka emandleni avuselelekayo. Ubuchwepheshe be-electrolysis yamanzi buhlanganisa kakhulu ubuchwepheshe be-alkaline water electrolysis, ubuchwepheshe be-proton exchange membrane (PEM) water electrolysis kanye nobuchwepheshe be-solid oxide electrolysis cell.

NgoMashi kulo nyaka, uLongi noZhuque batshale imali ebhizinisini elihlangene ukuze basungule inkampani yamandla e-hydrogen. ULi Zhenguo, umongameli weLongji, utshele intatheli evela e-China Securities News ukuthi ukuthuthukiswa “kwe-hydrogen eluhlaza” kudingeka kuqale ngokunciphisa izindleko zemishini yokukhiqiza amanzi esebenzisa ugesi kanye nokukhiqizwa kwamandla e-photovoltaic. Ngesikhathi esifanayo, ukusebenza kahle kwe-electrolyzer kuyathuthuka futhi ukusetshenziswa kwamandla kuyancishiswa. Imodeli “yokukhiqizwa kwe-photovoltaic + hydrogen” kaLongji ikhetha i-electrolysis yamanzi e-alkaline njengesiqondiso sayo sokuthuthukiswa.

"Ngokombono wezindleko zokukhiqiza imishini, i-platinum, i-iridium kanye nezinye izinsimbi eziyigugu zisetshenziswa njengezinto ze-electrode zokuhlanza i-proton exchange membrane electrolysis yamanzi. Izindleko zokukhiqiza imishini zihlala ziphezulu. Kodwa-ke, i-alkaline water electrolysis isebenzisa i-nickel njengezinto ze-electrode, okunciphisa kakhulu izindleko futhi kungahlangabezana nezidingo ze-electrolysis yamanzi esikhathini esizayo. Isidingo esikhulu semakethe ye-hydrogen." ULi Zhenguo uthe eminyakeni eyi-10 edlule, izindleko zokukhiqiza imishini ye-alkaline water electrolysis zincishisiwe ngo-60%. Esikhathini esizayo, ubuchwepheshe kanye nokuthuthukiswa kwenqubo yokuhlanganisa ukukhiqiza kunganciphisa kakhulu izindleko zokukhiqiza imishini.

Ngokuphathelene nokunciphisa izindleko zokukhiqizwa kukagesi we-photovoltaic, uLi Zhenguo ukholelwa ukuthi lokhu kuhlanganisa kakhulu izingxenye ezimbili: ukunciphisa izindleko zesistimu kanye nokwandisa ukukhiqizwa kukagesi womjikelezo wokuphila. “Ezindaweni ezinamahora angaphezu kuka-1,500 okukhanya kwelanga unyaka wonke, izindleko zokukhiqizwa kukagesi we-photovoltaic weLongi zingafinyelela ku-0.1 yuan/kWh.”
