Ukugcinwa nokuthuthwa kwe-hydrogen ewuketshezi kuyisisekelo sokusetshenziswa kwe-hydrogen ewuketshezi okuphephile, okusebenzayo, okukhulu nokungabizi kakhulu, kanye nesihluthulelo sokuxazulula ukusetshenziswa komzila wobuchwepheshe be-hydrogen.
 
Ukugcinwa nokuthuthwa kwe-hydrogen ewuketshezi kungahlukaniswa ngezinhlobo ezimbili: ukugcinwa kwesitsha kanye nokuthuthwa kwepayipi. Ngendlela yesakhiwo sokugcina, ithangi lokugcina eliyindilinga kanye nethangi lokugcina eliyindilinga ngokuvamile kusetshenziselwa ukugcina nokuthuthwa kwesitsha. Ngendlela yokuhamba, kusetshenziswa i-trailer ye-hydrogen ewuketshezi, imoto yesitimela se-hydrogen ewuketshezi kanye nomkhumbi wethangi le-hydrogen ewuketshezi.
 
Ngaphezu kokucabangela umthelela, ukudlidliza nezinye izici ezihilelekile enkambisweni yokuthuthwa koketshezi okuvamile, ngenxa yezinga eliphansi lokubila le-hydrogen ewuketshezi (20.3K), ukushisa okuncane okucashile kokuhwamuka kanye nezici zokuhwamuka kalula, indawo yokugcina kanye nokuthuthwa kwesitsha kumele kusebenzise izindlela zobuchwepheshe eziqinile zokunciphisa ukuvuza kokushisa, noma kusetshenziswe indawo yokugcina kanye nokuthuthwa okungonakalisi, ukunciphisa izinga lokuhwamuka kwe-hydrogen ewuketshezi kube okungenani noma kube yi-zero, ngaphandle kwalokho kuzobangela ukwanda komfutho wethangi. Kuholela engcupheni yokucindezela ngokweqile noma ekulahlekelweni kokuqhuma. Njengoba kuboniswe esithombeni esingezansi, ngokombono wezindlela zobuchwepheshe, indawo yokugcina kanye nokuthuthwa kwe-hydrogen ewuketshezi ikakhulukazi kusebenzisa ubuchwepheshe be-adiabatic obungasebenzi ukunciphisa ukuqhutshwa kokushisa kanye nobuchwepheshe bokuqandisa obusebenzayo obubekwe phezu kwalesi sisekelo ukunciphisa ukuvuza kokushisa noma ukukhiqiza amandla okupholisa engeziwe.
 
Ngokusekelwe ezicini zomzimba nezamakhemikhali ze-hydrogen ewuketshezi uqobo, indlela yayo yokugcina kanye nokuthutha inezinzuzo eziningi kunendlela yokugcina i-hydrogen enomfutho ophezulu esetshenziswa kabanzi eShayina, kodwa inqubo yayo yokukhiqiza eyinkimbinkimbi nayo yenza ibe nezinkinga ezithile.
 
Isilinganiso esikhulu sesisindo sokugcina, isitoreji esilula kanye nokuhamba kanye nemoto
Uma kuqhathaniswa nesitoreji se-hydrogen esinegesi, inzuzo enkulu ye-hydrogen ewuketshezi ukuminyana kwayo okuphezulu. Ukuminyana kwe-hydrogen ewuketshezi kungu-70.8kg/m3, okuphindwe ka-5, 3 kanye no-1.8 kunokwe-hydrogen enengcindezi ephezulu engu-20, 35, kanye no-70MPa ngokulandelana. Ngakho-ke, i-hydrogen ewuketshezi ifaneleka kakhulu ukugcina nokuthutha i-hydrogen ngezinga elikhulu, okungaxazulula izinkinga zokugcina nokuthutha amandla e-hydrogen.
 
Umfutho ophansi wokugcina, kulula ukuqinisekisa ukuphepha
Isitoreji se-hydrogen esiwuketshezi ngesisekelo sokufakwa kokushisa ukuqinisekisa ukuzinza kwesitsha, izinga lokucindezela lokugcina nokuthutha nsuku zonke liphansi (ngokuvamile liphansi kune-1MPa), liphansi kakhulu kunezinga lokucindezela lokugcina nokuthutha igesi elinomfutho ophezulu kanye ne-hydrogen, okulula ukuqinisekisa ukuphepha enkambisweni yokusebenza yansuku zonke. Uma kuhlanganiswa nezici zesilinganiso esikhulu sesisindo sokugcina i-hydrogen esiwuketshezi, esikhathini esizayo ukukhuthazwa okukhulu kwamandla e-hydrogen, isitoreji nokuthutha kwe-hydrogen esiwuketshezi (njengesiteshi se-hydrogenation esiwuketshezi) kuzoba nesistimu yokusebenza ephephile ezindaweni zasemadolobheni ezinobuningi bezakhiwo, inani labantu eliningi kanye nezindleko zomhlaba eziphezulu, futhi uhlelo lonke luzomboza indawo encane, ludinga izindleko zokutshalwa kwezimali zokuqala ezincane kanye nezindleko zokusebenza.
 
Ukuhlanzeka okuphezulu kokuhwamuka, ukuhlangabezana nezidingo ze-terminal
Ukusetshenziswa kwaminyaka yonke kwe-hydrogen emsulwa kakhulu kanye ne-hydrogen emsulwa kakhulu kukhulu, ikakhulukazi embonini ye-elekthronikhi (njenge-semiconductors, izinto ze-electro-vacuum, ama-silicon wafers, ukukhiqizwa kwe-optical fiber, njll.) kanye nensimu yamaseli kaphethiloli, lapho ukusetshenziswa kwe-hydrogen emsulwa kakhulu kanye ne-hydrogen emsulwa kakhulu kukhulu kakhulu. Njengamanje, ikhwalithi ye-hydrogen eminingi yezimboni ayikwazi ukuhlangabezana nezidingo eziqinile zabanye abasebenzisi bokugcina ngobumsulwa be-hydrogen, kodwa ubumsulwa be-hydrogen ngemva kokuhwamuka kwe-hydrogen ewuketshezi bungahlangabezana nezidingo.
 
Isitshalo sokukhiqiza uketshezi sitshalwe imali kakhulu futhi sisebenzisa amandla amaningi
Ngenxa yokubambezeleka ekuthuthukisweni kwemishini ebalulekile kanye nobuchwepheshe obufana namabhokisi abandayo e-hydrogen liquefaction, yonke imishini ye-hydrogen liquefaction ensimini yezindiza yasekhaya yayilawulwa yizinkampani zakwamanye amazwe ngaphambi kukaSepthemba 2021. Imishini emikhulu ye-hydrogen liquefaction core ingaphansi kwezinqubomgomo zokuhweba zakwamanye amazwe ezifanele (njengeMithetho Yokuphatha Ukuthunyelwa Kwamanye Amazwe yoMnyango Wezohwebo wase-US), evimbela ukuthunyelwa kwemishini kwamanye amazwe futhi ivimbele ukushintshaniswa kobuchwepheshe. Lokhu kwenza ukutshalwa kwezimali kokuqala kwemishini yesitshalo se-hydrogen liquefaction kube kukhulu, kuhlanganiswe nesidingo esincane sasekhaya se-hydrogen liquid civil, isilinganiso sokusebenza asanele, futhi isilinganiso samandla sikhuphuka kancane. Ngenxa yalokho, ukusetshenziswa kwamandla e-hydrogen ewuketshezi kuphezulu kunokwe-hydrogen yegesi enomfutho ophezulu.
 
Kukhona ukulahleka kokuhwamuka kwe-hydrogen enqubweni yokugcina kanye nokuthuthwa kwayo
Njengamanje, enkambisweni yokugcina nokuthutha i-hydrogen ewuketshezi, ukuhwamuka kwe-hydrogen okubangelwa ukuvuza kokushisa kuphathwa ngokufaka umoya, okuzoholela ekulahlekelweni komoya okubangelwa ukuhwamuka kwezinga elithile. Esikhathini esizayo sokugcina nokuthutha amandla e-hydrogen, kufanele kuthathwe izinyathelo ezengeziwe zokubuyisa igesi ye-hydrogen ehwamuka kancane ukuze kuxazululwe inkinga yokunciphisa ukusetshenziswa okubangelwa ukuvuza okuqondile.
 
Imishini ye-HL Cryogenic
I-HL Cryogenic Equipment eyasungulwa ngo-1992 iwuphawu oluhambisana ne-HL Cryogenic Equipment Company Cryogenic Equipment Co.,Ltd. I-HL Cryogenic Equipment izibophezele ekwakhiweni nasekukhiqizweni kwe-High Vacuum Insulated Cryogenic Piping System kanye ne-Support Equipment ehlobene nayo ukuze kuhlangatshezwane nezidingo ezahlukene zamakhasimende. I-Vacuum Insulated Pipe kanye ne-Flexible Hose zakhiwe nge-vacuum ephezulu kanye nezinto ezikhethekile zesikrini esiningi, futhi zidlula ochungechungeni lwezindlela zokwelapha zobuchwepheshe eziqinile kakhulu kanye nokwelashwa kwe-vacuum ephezulu, okusetshenziselwa ukudlulisa i-oxygen ewuketshezi, i-nitrogen ewuketshezi, i-argon ewuketshezi, i-hydrogen ewuketshezi, i-helium ewuketshezi, i-ethylene gas LEG ewuketshezi kanye ne-LNG yemvelo ewuketshezi.
