Ukugcinwa nokuthuthwa kwe-hydrogen enguketshezi kuyisisekelo sokusetshenziswa kwe-hydrogen ewuketshezi ephephile, ephumelelayo, enkulu futhi enezindleko eziphansi, futhi kuyisihluthulelo sokuxazulula ukusetshenziswa komzila wobuchwepheshe be-hydrogen.
 
Ukugcinwa nokuthuthwa kwe-hydrogen enguketshezi kungahlukaniswa ngezinhlobo ezimbili: ukugcinwa kweziqukathi kanye nokuthuthwa kwamapayipi. Ngendlela yesakhiwo sokugcina, ithangi lokugcina eliyindilinga kanye nethangi lokugcina eliyicylindrical ngokuvamile lisetshenziselwa ukugcinwa kweziqukathi nokuthutha. Ngendlela yokuthutha, kusetshenziswa i-trailer ye-hydrogen eyi-liquid, imoto yethangi le-liquid hydrogen railway kanye nomkhumbi we-liquid hydrogen tank.
 
Ngaphezu kokucabangela umthelela, ukudlidliza nezinye izici ezihilelekile ohlelweni lokuthuthwa koketshezi oluvamile, ngenxa yephuzu eliphansi lokubilisa le-hydrogen enguketshezi (20.3K), ukushisa okuncane okucashile kokuhwamuka nezici zokuhwamuka okulula, indawo yokugcina izinto nezinto zokuhamba kufanele. sebenzisa izindlela zobuchwepheshe eziqinile zokunciphisa ukuvuza kokushisa, noma ukusebenzisa isitoreji nokuthuthwa okungangonakali, ukuze kuncishiswe izinga lokuhwamuka kwe-hydrogen ewuketshezi libe lincane noma libe nguziro, ngaphandle kwalokho kuzodala ukukhuphuka komfutho wethangi. Kuholela engcupheni yokucindezela ngokweqile noma ukulahlekelwa kokushaywa umoya. Njengoba kuboniswe emfanekisweni ongezansi, ngokombono wezindlela zobuchwepheshe, isitoreji se-hydrogen ewuketshezi kanye nezokuthutha ikakhulukazi zisebenzisa ubuchwepheshe be-adiabatic obungashintshile ukuze kuncishiswe ukuqhutshwa kokushisa nobuchwepheshe besiqandisi obusebenzayo obubekwe phezu kwalesi sisekelo ukuze kuncishiswe ukuvuza kokushisa noma ukukhiqiza amandla okupholisa okwengeziwe.
 
Ngokusekelwe ezintweni ezibonakalayo namakhemikhali e-hydrogen enguketshezi ngokwayo, imodi yayo yokugcina nokuthutha inezinzuzo eziningi ngaphezu kwemodi yokugcina i-hydrogen enomfutho ophezulu wegesi esetshenziswa kabanzi eShayina, kodwa inqubo yayo yokukhiqiza eyinkimbinkimbi futhi iyenza ibe nokubi okuthile.
 
Isilinganiso esikhulu sesisindo sokugcina, isitoreji esikahle kanye nezinto zokuhamba kanye nemoto
Uma kuqhathaniswa nokugcinwa kwe-hydrogen enegesi, inzuzo enkulu ye-hydrogen enguketshezi ukuminyana kwayo okuphezulu. Ukuminyana kwe-hydrogen ewuketshezi ngu-70.8kg/m3, okungama-5, 3 kanye no-1.8 izikhathi eziphindwe ka-20, 35, kanye no-70MPa high-pressure hydrogen ngokulandelanayo. Ngakho-ke, i-hydrogen ewuketshezi ifaneleka kakhulu ukugcinwa nokuthuthwa kwe-hydrogen ngezinga elikhulu, okungaxazulula izinkinga zokugcinwa kwamandla e-hydrogen nokuhamba.
 
Ukucindezela okuphansi kwesitoreji, kulula ukuqinisekisa ukuphepha
Isitoreji se-hydrogen ewuketshezi ngesisekelo sokufakwa ukuze kuqinisekiswe ukuzinza kwesitsha, izinga lokucindezela kokugcinwa kwansuku zonke nokuthutha liphansi (ngokuvamile liphansi kune-1MPa), liphansi kakhulu kunezinga lokucindezela kwegesi ephezulu yokucindezela kanye nokugcinwa kwe-hydrogen nezokuthutha, okuyinto elula ukuqinisekisa ukuphepha ohlelweni lokusebenza nsuku zonke. Kuhlanganiswe nezici zesilinganiso esikhulu sesisindo soketshezi lwe-hydrogen, esikhathini esizayo ukukhuthazwa okukhulu kwamandla e-hydrogen, ukugcinwa kwe-hydrogen ewuketshezi kanye nezinto zokuhamba (njengesiteshi se-hydrogen hydrogenation ewuketshezi) kuzoba nohlelo lokusebenza oluphephile ezindaweni zasemadolobheni ezinobuningi bezakhiwo, inani labantu eliminyene kanye nezindleko zomhlaba eziphezulu, futhi uhlelo lulonke luzohlanganisa indawo encane, edinga izindleko zokuqala zokutshala izimali kanye nezindleko zokusebenza.
 
Ukuhlanzeka okuphezulu kwe-vaporization, ukuhlangabezana nezidingo zetheminali
Ukusetshenziswa kwaminyaka yonke kwe-hydrogen ehlanzekile ne-ultra-pure hydrogen kukhulu, ikakhulukazi embonini ye-electronics (njengama-semiconductors, izinto zokwakha ze-electro-vacuum, ama-silicon wafers, ukukhiqizwa kwe-fiber optical, njll.) kanye nenkundla yamaseli kaphethiloli, lapho ukusetshenziswa ukuhlanzeka okuphezulu i-hydrogen ne-ultra-pure hydrogen inkulu kakhulu. Njengamanje, ikhwalithi ye-hydrogen yezimboni eminingi ayikwazi ukuhlangabezana nezidingo eziqinile zabanye abasebenzisi bokugcina mayelana nokuhlanzeka kwe-hydrogen, kodwa ukuhlanzeka kwe-hydrogen ngemva kokuhwamuka kwe-hydrogen enguketshezi kungahlangabezana nezidingo.
 
Imboni ye-Liquefaction inokutshalwa kwezimali okuphezulu kanye nokusetshenziswa kwamandla okuphezulu
Ngenxa yokubambezeleka ekuthuthukisweni kwemishini ebalulekile kanye nobuchwepheshe obunjengamabhokisi abandayo e-hydrogen liquefaction, zonke izinto zokusebenza ze-hydrogen zokukhiqiza uketshezi endaweni yasekhaya zaphathwa izinkampani zakwamanye amazwe ngaphambi kuka-September 2021. Imishini emikhulu ye-hydrogen liquefaction core ingaphansi kohwebo olufanele lwangaphandle. izinqubomgomo (ezifana neMithetho Yokuphatha Ukuthekelisa yoMnyango Wezohwebo wase-US), ekhawulela ukuthunyelwa kwezinto zokusebenza futhi evimbela ukushintshaniswa kobuchwepheshe. Lokhu kwenza ukuthi utshalomali lwemishini yokuqala ye-hydrogen liquefaction plant lube lukhulu, kuhlanganiswe nesidingo esincane sasekhaya se-civil liquid hydrogen, isikali sokusetshenziswa asanele, futhi isikali somthamo sikhuphuka kancane. Ngenxa yalokho, ukusetshenziswa kweyunithi yokukhiqiza amandla e-hydrogen ewuketshezi kuphezulu kunaleyo ye-high-pressure gas hydrogen.
 
Kukhona ukulahleka kokuhwamuka ohlelweni lokugcinwa kwe-hydrogen ewuketshezi kanye nokuhamba
Njengamanje, ekugcinweni nasekuthuthweni kwe-hydrogen ewuketshezi, ukuhwamuka kwe-hydrogen okubangelwa ukuvuza kokushisa kulawulwa ngokukhipha umoya, okuzoholela ezingeni elithile lokulahlekelwa ukuhwamuka. Esikhathini esizayo sokugcinwa kwamandla e-hydrogen kanye nezokuthutha, izinyathelo ezengeziwe kufanele zithathwe ukuze kubuyiselwe igesi ye-hydrogen ehwamuke kancane ukuze kuxazululwe inkinga yokunciphisa ukusetshenziswa okubangelwa ukushaywa umoya okuqondile.
