NgoMeyi 8, i-RAG yase-Austrian yasungula iprojekthi yokulinga yokugcina i-hydrogen ephantsi komhlaba kwindawo eyayisakuba yindawo yokugcina igesi eRubensdorf. Iprojekthi yokulinga iya kugcina i-1.2 yesigidi se-cubic metres ye-hydrogen, elingana ne-4.2 GWh yombane. I-hydrogen egciniweyo iya kuveliswa yi-2 MW yeproton ye-membrane ye-membrane ye-proton enikezelwa yi-Cummins, eya kuqala isebenze kumthwalo wesiseko ukuvelisa i-hydrogen eyaneleyo yokugcina. Kamva kwiprojekthi, iseli iya kusebenza ngendlela eguquguqukayo ngakumbi ukudlulisa umbane ohlaziyekayo ogqithisileyo kwigridi.
Njengesiganeko esibalulekileyo kuphuhliso loqoqosho lwe-hydrogen, iprojekthi yokulinga iya kubonisa amandla okugcina i-hydrogen engaphantsi komhlaba yokugcina amandla exesha lonyaka kwaye ivule indlela yokusasazwa okukhulu kwamandla e-hydrogen. Ngelixa kusekho imiceli mngeni emininzi ekufuneka yoyiswe, eli linyathelo elibalulekileyo elisingise kwinkqubo yamandla ezinzileyo nencitshisiweyo.
Ukugcinwa kwehydrogen engaphantsi komhlaba, oko kukuthi, ukusetyenziswa kwesakhiwo sejoloji sangaphantsi komhlaba kugcino olukhulu lwamandla e-hydrogen. Ukuvelisa umbane kwimithombo yamandla ahlaziyekayo kunye nokuvelisa i-hydrogen, i-hydrogen itofwa kwizakhiwo zejoloji ezingaphantsi komhlaba ezifana nemiqolomba yetyuwa, i-oyile ephelileyo kunye namadama egesi, i-aquifers kunye nemiqolomba eqinile yamatye ukuze kufezekiswe ukugcinwa kwamandla e-hydrogen. Xa kuyimfuneko, i-hydrogen inokukhutshwa kwiindawo zokugcina i-hydrogen engaphantsi komhlaba ukwenzela igesi, ukuveliswa kwamandla okanye ezinye iinjongo.
Amandla eHydrojeni anokugcinwa kwiintlobo ngeentlobo, kubandakanya irhasi, ulwelo, i-adsorption yomphezulu, ihydride okanye ulwelo ngemizimba yehydrogen ekwibhodi. Nangona kunjalo, ukuze uqonde ukusebenza kakuhle kwegridi yamandla ancedisayo kunye nokuseka inethiwekhi yamandla e-hydrogen egqibeleleyo, ukugcinwa kwe-hydrogen engaphantsi komhlaba yeyona ndlela inokwenzeka ngoku. Iindlela zomphezulu wogcino lwe-hydrogen, njengemibhobho okanye iitanki, zinogcino olulinganiselweyo kunye nomthamo wokukhupha weentsuku ezimbalwa kuphela. Ugcino lwe-hydrogen olungaphantsi komhlaba luyafuneka ukunika ugcino lwamandla kwisikali seeveki okanye iinyanga. Ukugcinwa kwehydrogen engaphantsi komhlaba kunokuhlangabezana ukuya kutsho kwiinyanga ezininzi zeemfuno zogcino lwamandla, inokukhutshwa ukuze isetyenziswe ngokuthe ngqo xa ifuneka, okanye inokuguqulwa ibe ngumbane.
Nangona kunjalo, ukugcinwa kwe-hydrogen phantsi komhlaba kujongene nemingeni emininzi:
Okokuqala, uphuhliso lobuchwepheshe lucotha
Okwangoku, uphando, uphuhliso kunye nomboniso ofunekayo ukuze ugcinwe kwiindawo zegesi eziphelileyo kunye ne-aquifers iyacotha. Uphononongo olongezelelekileyo luyafuneka ukuvavanya iziphumo zerhasi yendalo eshiyekileyo kwiindawo eziphelelweyo, kwi-situ reactions yebhaktiriya kwi-aquifers kunye nemimandla yegesi ephelileyo enokuvelisa ukungcola kunye nelahleko ye-hydrogen, kunye nemiphumo yokugcinwa kwe-tightness enokuthi ichatshazelwe ziipropati ze-hydrogen.
Okwesibini, ixesha lokwakhiwa kweprojekthi lide
Iiprojekthi zokugcinwa kwerhasi engaphantsi komhlaba zifuna ixesha elide lokwakha, iminyaka emihlanu ukuya kweli-10 kwimiqolomba yetyuwa kunye namadama aphelileyo, kunye neminyaka eli-10 ukuya kweli-12 yokugcina i-aquifer. Kwiiprojekthi zokugcina i-hydrogen, kunokubakho ixesha elikhulu.
3. Ukunyinwa ziimeko zejoloji
Imeko yendawo yokwakheka komhlaba imisela amandla okugcina igesi ephantsi komhlaba. Kwiindawo ezinomlinganiselo olinganiselweyo, i-hydrogen inokugcinwa kwinqanaba elikhulu njenge-liquid carrier ngokusebenzisa inkqubo yokuguqulwa kweekhemikhali, kodwa ukuguqulwa kwamandla okusebenza kuyancitshiswa.
Nangona amandla e-hydrogen engazange asetyenziswe kwizinga elikhulu ngenxa yokusebenza kwayo okuphantsi kunye neendleko eziphezulu, inethemba lophuhliso olubanzi kwixesha elizayo ngenxa yendima yalo ephambili kwi-decarbonization kwiinkalo ezahlukeneyo ezibalulekileyo.
