Ngomhlaka-8 Meyi, i-RAG yase-Austria yethule iphrojekthi yokuqala yomhlaba yokugcina i-hydrogen ngaphansi komhlaba endaweni eyayiyi-gas depot eRubensdorf. Iphrojekthi yokuhlola izogcina ama-cubic metres ayizigidi ezingu-1.2 e-hydrogen, alingana no-4.2 GWh kagesi. I-hydrogen egciniwe izokhiqizwa yiseli le-membrane ye-proton exchange membrane elingu-2 MW elinikezwa yi-Cummins, elizoqala ukusebenza kumthwalo wesisekelo ukukhiqiza i-hydrogen eyanele yokugcina. Kamuva kuphrojekthi, iseli lizosebenza ngendlela eguquguqukayo ukuze lidlulisele ugesi ovuselelekayo owengeziwe kugridi.
Njengesinyathelo esibalulekile ekuthuthukisweni komnotho we-hydrogen, iphrojekthi yokuhlola izobonisa amandla okugcina i-hydrogen ngaphansi komhlaba ukuze kugcinwe amandla esizini futhi ivule indlela yokusetshenziswa okukhulu kwamandla e-hydrogen. Nakuba kusenezinselele eziningi okumelwe zinqotshwe, lesi ngokuqinisekile isinyathelo esibalulekile esibheke ohlelweni lwamandla oluhlala isikhathi eside nolungenawo ama-carbon.
Isitoreji se-hydrogen esingaphansi komhlaba, okungukuthi kusetshenziswa isakhiwo se-geological esingaphansi komhlaba ukugcina amandla e-hydrogen ngezinga elikhulu. Ikhiqiza ugesi ovela emithonjeni yamandla avuselelekayo futhi ikhiqize i-hydrogen, i-hydrogen ifakwa ezakhiweni ze-geological ezingaphansi komhlaba njengemihume kasawoti, izindawo zokugcina uwoyela negesi eziphelelwe yisikhathi, ama-aquifer kanye nemihume yamadwala aqinile ukuze kufezwe ukugcinwa kwamandla e-hydrogen. Uma kudingeka, i-hydrogen ingakhishwa ezindaweni zokugcina i-hydrogen ezingaphansi komhlaba ukuze kusetshenziswe igesi, ukukhiqiza ugesi noma ezinye izinjongo.
Amandla e-hydrogen angagcinwa ngezindlela ezahlukene, okuhlanganisa igesi, uketshezi, ukumuncwa komhlaba, i-hydride noma uketshezi olunemizimba ye-hydrogen esebhodini. Kodwa-ke, ukuze kufezwe ukusebenza okubushelelezi kwegridi yamandla asekelayo futhi kusungulwe inethiwekhi yamandla e-hydrogen ephelele, isitoreji se-hydrogen esingaphansi komhlaba yiyona ndlela kuphela engenzeka njengamanje. Izinhlobo zokugcinwa kwe-hydrogen, njengemipayipi noma amathangi, zinomthamo wokugcina nokukhipha olinganiselwe wezinsuku ezimbalwa kuphela. Isitoreji se-hydrogen esingaphansi komhlaba siyadingeka ukuze kuhlinzekwe isitoreji samandla esikalini samasonto noma izinyanga. Isitoreji se-hydrogen esingaphansi komhlaba singahlangabezana nezidingo zokugcina amandla ezifika ezinyangeni eziningana, singakhishwa ukuze sisetshenziswe ngqo lapho sidingeka, noma singaguqulwa sibe ugesi.
Kodwa-ke, isitoreji se-hydrogen esingaphansi komhlaba sibhekene nezinselele eziningana:
Okokuqala, intuthuko yezobuchwepheshe ihamba kancane
Njengamanje, ucwaningo, intuthuko kanye nokuboniswa okudingekayo ukuze kugcinwe ezindaweni zegesi eziphelelwe yisikhathi kanye nasezindaweni zamanzi angaphansi komhlaba kuhamba kancane. Kudingeka izifundo ezengeziwe ukuze kuhlolwe imiphumela yegesi yemvelo esele ezindaweni eziphelelwe yisikhathi, ukusabela kwamagciwane endaweni yaso emanzini angaphansi komhlaba kanye nasezindaweni zegesi eziphelelwe yisikhathi ezingase zikhiqize ukungcola kanye nokulahleka kwe-hydrogen, kanye nemiphumela yokuqina kwesitoreji okungase kuthintwe yizakhiwo ze-hydrogen.
Okwesibili, isikhathi sokwakhiwa kwephrojekthi side kakhulu
Amaphrojekthi okugcina igesi ngaphansi komhlaba adinga isikhathi sokwakha esikhulu, iminyaka emihlanu kuya kweyi-10 yemihume kasawoti kanye namachibi aphelile, kanye neminyaka eyi-10 kuya kweyi-12 yokugcina amanzi angaphansi komhlaba. Kumaphrojekthi okugcina i-hydrogen, kungase kube nesikhathi eside kakhulu.
3. Kunqunyelwe yizimo zejoloji
Indawo ezungezile yendawo inquma amandla ezindawo zokugcina igesi ezingaphansi komhlaba. Ezindaweni ezinamandla amancane, i-hydrogen ingagcinwa ngezinga elikhulu njengomthwali woketshezi ngenqubo yokuguqulwa kwamakhemikhali, kodwa ukusebenza kahle kokuguqulwa kwamandla nakho kuncishisiwe.
Nakuba amandla e-hydrogen engasetshenziswanga ngezinga elikhulu ngenxa yokusebenza kahle okuphansi kanye nezindleko eziphakeme, anethuba elikhulu lokuthuthuka esikhathini esizayo ngenxa yendima yawo ebalulekile ekususeni i-carbonization emikhakheni ehlukahlukene ebalulekile.
