Ngokwesizindalwazi se-Energyportal ye-European Union, imboni yezamandla ingaphambi koshintsho olukhulu ngenxa yempumelelo emisha kubuchwepheshe bokukhiqiza i-algae hydrogen.Lobu buchwepheshe bezinguquko buthembisa ukubhekana nesidingo esiphuthumayo samandla ahlanzekile, avuselelekayo kuyilapho kunciphisa umthelela wemvelo wezindlela ezivamile zokukhiqiza amandla.
Ulwelwe, izidalwa eziluhlaza okotshani ezivame ukutholakala emachibini nasezilwandle, manje seziyadunyiswa njengekusasa lamandla avuselelekayo.Izinhlobo ezithile zolwelwe zingakhiqiza igesi ye-hydrogen, umthombo wamandla ahlanzekile novuselelekayo, ngokusebenzisa i-photosynthesis, ososayensi nabacwaningi bathole.
Amandla okukhiqizwa kwe-hydrogen kusuka ku-algae asekwazini kwawo ukuhlinzeka ngenye indlela esimeme futhi evumelana nemvelo kumafutha ezinto ezimbiwa phansi.Lapho i-hydrogen isetshenziswa njengophethiloli, amanzi akhiqizwa njengomunye umkhiqizo, ngakho awumthombo wamandla ohlanzeke kakhulu.Kodwa-ke, izindlela ezivamile zokukhiqiza i-hydrogen ngokuvamile zibandakanya ukusetshenziswa kwegesi yemvelo noma ezinye izinto zokubasa ezimbiwa phansi, okuholela ekukhishweni kwesisi esibamba ukushisa.Ngokuphambene, ukukhiqizwa kwe-hydrogen okusekelwe ku-algae kunikeza isisombululo kule nkinga yemvelo.Le nqubo ihilela ukutshala ulwelwe ngobuningi, lububeke ekukhanyeni kwelanga, nokuvuna i-hydrogen oluyikhiqizayo.Le ndlela ayigcini nje ngokuqeda isidingo samafutha ezinto ezimbiwa phansi, kodwa futhi isiza ukunciphisa amazinga e-carbon dioxide emkhathini, njengoba ulwelwe lumunca i-carbon dioxide ngesikhathi se-photosynthesis.
Ngaphezu kwalokho, ama-algae ayizinto eziphilayo ezisebenzayo.Uma kuqhathaniswa nezitshalo zasemhlabeni, zingakhiqiza i-biomass ephindwe ka-10 endaweni ngayinye, okuzenza zibe imithombo ekahle yokukhiqizwa kwe-hydrogen ngezinga elikhulu.Ngaphezu kwalokho, ulwelwe lungakhula ezindaweni ezihlukahlukene, okuhlanganisa amanzi anosawoti, amanzi anosawoti, namanzi angcolile, ngaleyo ndlela angaqhudelani nemithombo yamanzi ahlanzekile ukuze asetshenziswe abantu kanye nezolimo.
Nokho, naphezu kwamandla okukhiqizwa kwe-algal hydrogen, iphinde ibhekane nezinselele.Inqubo njengamanje iyabiza futhi idinga ucwaningo olwengeziwe nokuthuthukiswa ukuze ikwazi ukuhwebelana.Ukusebenza kahle kokukhiqizwa kwe-hydrogen nakho kudingeka kuthuthukiswe, njengoba ingxenye encane yokukhanya kwelanga emuncwa ulwelwe iguqulwa ibe i-hydrogen.
Noma kunjalo, amandla e-algae okukhiqiza i-hydrogen awanakuzitshwa.Lokhu kuqanjwa kabusha kungase kudlale indima ebalulekile ekuguquleni umkhakha wezamandla njengoba isidingo somhlaba wonke samandla ahlanzekile, avuselelekayo silokhu sikhula.Ukutshalwa kwezimali ocwaningweni nasekuthuthukisweni, kuhambisana nezinqubomgomo ezisekelayo zikahulumeni, kungasheshisa ukuthengiswa kwalobu buchwepheshe.Ukuthuthukisa izindlela ezisebenzayo nezingabizi kakhulu zokutshala ulwelwe, ukukhipha i-hydrogen, nokugcinwa nakho kungase kuvule indlela yokwamukelwa ngezinga elikhulu lobuchwepheshe.
Sengiphetha, ukukhiqizwa kwe-hydrogen kusuka ku-algae kuyindlela ethembisayo yokukhiqiza amandla esimeme.Ihlinzeka ngomthombo wamandla ohlanzekile, ovuselelekayo ongasiza ukunciphisa umthelela wemvelo wezindlela ezivamile zokukhiqiza amandla.Nakuba izinselele zisekhona, makhulu amathuba okuthi lobu buchwepheshe buguqule imboni yezamandla.Ngocwaningo oluqhubekayo nentuthuko, ukukhiqizwa kwe-hydrogen olwelweni kungase kube umthelela obalulekile engxubevange yamandla omhlaba, kungenise inkathi entsha yokukhiqizwa kwamandla okusimeme kanye nemvelo.
