Ngokusho kwewebhusayithi ye-energyportal ye-European Union, imboni yamandla iseduze noshintsho olukhulu ngenxa yokuthuthuka okusha kobuchwepheshe bokukhiqiza i-hydrogen ye-algae. Lobu buchwepheshe obushintshayo buthembisa ukubhekana nesidingo esiphuthumayo samandla ahlanzekile, avuselelekayo ngenkathi kunciphisa umthelela wezemvelo wezindlela zokukhiqiza amandla ezivamile.
I-algae, izinto eziphilayo eziluhlaza okotshani ezivame ukutholakala emachibini nasezilwandle, manje isibizwa ngokuthi ikusasa lamandla avuselelekayo. Izinhlobo ezithile ze-algae zingakhiqiza igesi ye-hydrogen, umthombo wamandla ohlanzekile futhi ovuselelekayo, ngokusebenzisa i-photosynthesis, ososayensi nabacwaningi bathole.
Amandla okukhiqizwa kwe-hydrogen kusuka ku-algae atholakala emandleni ayo okuhlinzeka ngenye indlela eqhubekayo nenobungani nemvelo esikhundleni samafutha emvelo. Uma i-hydrogen isetshenziswa njengophethiloli, amanzi akhiqizwa njengomkhiqizo ophumayo, ngakho-ke iwumthombo wamandla ohlanzekile kakhulu. Kodwa-ke, izindlela zokukhiqiza i-hydrogen ezivamile ngokuvamile zihilela ukusetshenziswa kwegesi yemvelo noma amanye amafutha emvelo, okuholela ekukhishweni kwegesi ebamba ukushisa. Ngokuphambene nalokho, ukukhiqizwa kwe-hydrogen okusekelwe ku-algae kunikeza ikhambi lale nkinga yezemvelo. Le nqubo ihilela ukukhulisa u-algae ngobuningi, ukububeka elangeni, kanye nokuvuna i-hydrogen abayikhiqizayo. Le ndlela ayigcini nje ngokuqeda isidingo samafutha emvelo, kodwa futhi isiza ekunciphiseni amazinga e-carbon dioxide asemoyeni, njengoba u-algae emunca i-carbon dioxide ngesikhathi se-photosynthesis.
Ngaphezu kwalokho, ulwelwe luyizinto eziphilayo ezisebenzayo. Uma luqhathaniswa nezitshalo zasemhlabeni, lungakhiqiza i-biomass ephindwe kayishumi endaweni ngayinye, okwenza kube imithombo efanelekile yokukhiqizwa kwe-hydrogen enkulu. Ngaphezu kwalokho, ulwelwe lungakhula ezindaweni ezahlukahlukene, okuhlanganisa amanzi anosawoti, amanzi anosawoti, kanye namanzi angcolile, ngaleyo ndlela lungancintisani nemithombo yamanzi ahlanzekile ekusetshenzisweni kwabantu kanye nezolimo.
Kodwa-ke, naphezu kwamandla okukhiqizwa kwe-algal hydrogen, nayo ibhekene nezinselele. Le nqubo okwamanje ibiza kakhulu futhi idinga ucwaningo olwengeziwe kanye nentuthuko ukuze ikwazi ukuhweba. Ukusebenza kahle kokukhiqizwa kwe-hydrogen nakho kudinga ukuthuthukiswa, njengoba ingxenye encane kuphela yokukhanya kwelanga okumuncwa yi-algae iguqulwa ibe yi-hydrogen.
Noma kunjalo, amandla e-algae okukhiqiza i-hydrogen awakwazi ukunakwa. Lokhu kusungula izinto ezintsha kungadlala indima ebalulekile ekuguquleni umkhakha wamandla njengoba isidingo somhlaba wonke samandla ahlanzekile, avuselelekayo siqhubeka nokukhula. Ukutshalwa kwezimali ocwaningweni nasekuthuthukisweni, kanye nezinqubomgomo zikahulumeni ezisekelayo, kungasheshisa ukuthengiswa kwalobu buchwepheshe. Ukuthuthukisa izindlela ezisebenzayo nezingabizi kakhulu zokutshala i-algae, ukukhipha i-hydrogen, kanye nokugcina kungase kuvule indlela yokwamukelwa kobuchwepheshe ngezinga elikhulu.
Ekuphetheni, ukukhiqizwa kwe-hydrogen kusuka ku-algae kuyindlela ethembisayo yokukhiqizwa kwamandla okusimeme. Kuhlinzeka ngomthombo wamandla ohlanzekile, ovuselelekayo ongasiza ekunciphiseni umthelela wezemvelo wezindlela zokukhiqiza amandla ezivamile. Nakuba kusenezinselelo, amathuba alobu buchwepheshe okuguqula imboni yamandla makhulu kakhulu. Ngocwaningo oluqhubekayo nentuthuko, ukukhiqizwa kwe-hydrogen kusuka ku-algae kungaba nomthelela obalulekile ekuxubeni kwamandla omhlaba wonke, okuholela enkathini entsha yokukhiqizwa kwamandla okusimeme futhi okunobungani nemvelo.
