Ngomhla wesi-8 kuCanzibe, i-RAG yase-Austria yaqalisa iprojekthi yokuqala yovavanyo lokugcina i-hydrogen phantsi komhlaba kwindawo eyayisakuba yindawo yokugcina igesi eRubensdorf. Le projekthi yovavanyo iza kugcina i-1.2 yezigidi zee-cubic metres ze-hydrogen, ezilingana ne-4.2 GWh yombane. I-hydrogen egciniweyo iya kuveliswa yiseli ye-2 MW ye-proton exchange membrane ebonelelwa yiCummins, eya kuqala isebenze kumthwalo wesiseko ukuvelisa i-hydrogen eyaneleyo yokugcina. Kamva kwiprojekthi, iseli iya kusebenza ngendlela eguquguqukayo yokudlulisela umbane ohlaziyekayo ogqithisileyo kwigridi.
Njengenyathelo elibalulekileyo kuphuhliso loqoqosho lwe-hydrogen, iprojekthi yovavanyo iya kubonisa amandla okugcinwa kwe-hydrogen phantsi komhlaba ukuze kugcinwe amandla onyaka kwaye ivule indlela yokusetyenziswa kwamandla e-hydrogen ngobuninzi. Nangona kusekho imingeni emininzi ekufuneka iyoyiswe, ngokuqinisekileyo eli linyathelo elibalulekileyo eliya kwinkqubo yamandla ezinzileyo nengafakwanga i-carbon.
Ugcino lwehydrogen phantsi komhlaba, oko kukuthi, kusetyenziswa isakhiwo sejoloji esingaphantsi komhlaba ukugcina amandla ehydrogen ngobuninzi. Ukuvelisa umbane kwimithombo yamandla ahlaziyekayo nokuvelisa ihydrogen, ihydrogen ifakwa kwizakhiwo zejoloji ezingaphantsi komhlaba ezifana nemiqolomba yetyuwa, iindawo zokugcina ioyile negesi eziphelileyo, aquifers kunye nemiqolomba yamatye aqinileyo ukuze kufunyanwe ugcino lwamandla ehydrogen. Xa kuyimfuneko, ihydrogen inokukhutshwa kwiindawo zokugcina ihydrogen phantsi komhlaba ukuze ifumane igesi, ukuveliswa kombane okanye ezinye iinjongo.
Amandla e-hydrogen angagcinwa ngeendlela ezahlukeneyo, kuquka igesi, ulwelo, ukufunxwa komphezulu, i-hydride okanye ulwelo olunemizimba ye-hydrogen ekwibhodi. Nangona kunjalo, ukuze kufezekiswe ukusebenza kakuhle kwegridi yamandla ancedisayo kunye nokuseka inethiwekhi yamandla e-hydrogen egqibeleleyo, ukugcinwa kwe-hydrogen engaphantsi komhlaba yeyona ndlela isebenzayo okwangoku. Iindlela zokugcina i-hydrogen ezingaphantsi komhlaba, ezifana nemibhobho okanye iitanki, zinomthamo wokugcina kunye nokukhupha olinganiselweyo weentsuku ezimbalwa kuphela. Ukugcinwa kwe-hydrogen engaphantsi komhlaba kuyafuneka ukuze kubonelelwe ngokugcinwa kwamandla kwisikali seeveki okanye iinyanga. Ukugcinwa kwe-hydrogen engaphantsi komhlaba kunokuhlangabezana neemfuno zokugcina amandla ukuya kuthi ga kwiinyanga ezininzi, kunokukhutshwa ukuze kusetyenziswe ngokuthe ngqo xa kufuneka, okanye kunokuguqulwa kube ngumbane.
Nangona kunjalo, ukugcinwa kwehydrogen phantsi komhlaba kujongene nemingeni emininzi:
Okokuqala, uphuhliso lwetekhnoloji lucotha
Okwangoku, uphando, uphuhliso kunye nomboniso ofunekayo wokugcina kwiindawo zegesi eziphelileyo kunye neendawo zamanzi amdaka zicotha. Kufuneka uphando olongezelelekileyo ukuze kuvavanywe imiphumo yegesi yendalo eseleyo kwiindawo eziphelileyo, iimpendulo zebhaktheriya kwindawo yazo kwiindawo zamanzi amdaka kunye neendawo zegesi eziphelileyo ezinokubangela ukungcola kunye nokulahleka kwe-hydrogen, kunye nemiphumo yokuqina kokugcinwa okunokuchaphazeleka ziimpawu ze-hydrogen.
Okwesibini, ixesha lokwakhiwa kweprojekthi lide
Iiprojekthi zokugcina igesi phantsi komhlaba zifuna ixesha elide lokwakha, iminyaka emihlanu ukuya kweli-10 kwimiqolomba yetyuwa kunye neendawo zokugcina amanzi eziphelileyo, kunye neminyaka eli-10 ukuya kweli-12 yokugcina amanzi amdaka. Kwiiprojekthi zokugcina i-hydrogen, kunokubakho ixesha elide.
3. Inqunyelwe ziimeko zejoloji
Imeko-bume yendawo yejoloji imisela amandla eendawo zokugcina igesi phantsi komhlaba. Kwiindawo ezinamandla amancinci, i-hydrogen inokugcinwa ngomlinganiselo omkhulu njengomthwali wolwelo ngenkqubo yokuguqula iikhemikhali, kodwa ukusebenza kakuhle kokuguqula amandla nako kuyancitshiswa.
Nangona amandla e-hydrogen engakhange asetyenziswe ngomlinganiselo omkhulu ngenxa yokusebenza kwawo okuphantsi kunye neendleko eziphezulu, anethuba elikhulu lophuhliso kwixesha elizayo ngenxa yendima yawo ephambili ekususeni i-carbonization kwiindawo ezahlukeneyo ezibalulekileyo.
