Sekureva kwewebhusaiti yeEnergyportal yeEuropean Union, indasitiri yesimba iri pedyo nekuchinja kukuru nekuda kwekuvandudzwa kuri kuitwa tekinoroji yekugadzira hydrogen kubva mualgae. Iyi tekinoroji inochinja-chinja inovimbisa kugadzirisa kudiwa kukuru kwesimba rakachena, rinogona kuvandudzwa ukuwo ichideredza kukanganisa kwezvakatipoteredza kwenzira dzemazuva ano dzekugadzira simba.
Algae, zvisikwa zvakasvibira zvine matope zvinowanikwa mumadziva nemumakungwa, zvava kunzi ndezveramangwana resimba rinogona kuvandudzwa. Masayendisiti nevaongorori vakaona kuti mamwe marudzi ealgae anogona kugadzira gasi rehydrogen, simba rakachena uye rinogona kuvandudzwa kuburikidza ne photosynthesis.
Kugona kwekugadzirwa kwehydrogen kubva mualgae kuri mukukwanisa kwayo kupa imwe nzira inogara kwenguva refu uye isingakuvadzi nharaunda panzvimbo pemafuta efossil. Kana hydrogen ikashandiswa semafuta, mvura inogadzirwa sechinhu chinobva pairi, saka isimba rakachena kwazvo. Zvisinei, nzira dzekugadzira hydrogen dzakajairika dzinowanzo sanganisira kushandiswa kwegasi rechisikigo kana mamwe mafuta efossil, zvichikonzera kuburitswa kwegasi rinopisa pasi pevhu. Kusiyana neizvi, kugadzirwa kwehydrogen kubva mualgae kunopa mhinduro kune dambudziko iri rezvakatipoteredza. Maitiro aya anosanganisira kukura algae muhuwandu hwakawanda, kuaisa pachiedza chezuva, uye kuunganidza hydrogen yaanogadzira. Maitiro aya haangobvisi chete kudiwa kwemafuta efossil, asiwo anobatsira kuderedza mwero wecarbon dioxide mumhepo, sezvo algae ichitora carbon dioxide panguva yephotosynthesis.
Uyezve, algae zvipenyu zvinoshanda zvakanaka. Kana zvichienzaniswa nemiti yepasi, zvinogona kugadzira biomass yakapetwa kagumi pachikamu chimwe nechimwe, zvichiita kuti zvive nzvimbo yakanaka yekugadzira hydrogen yakawanda. Pamusoro pezvo, algae inogona kukura munzvimbo dzakasiyana-siyana, kusanganisira mvura yemunyu, mvura ine brackish, uye mvura yakasviba, nokudaro isingakwikwidzane nezviwanikwa zvemvura yakachena zvinoshandiswa nevanhu uye kurima.
Zvisinei, pasinei nekukwanisa kwekugadzira hydrogen kubva mualgal, inosanganawo nematambudziko. Maitiro aya parizvino anodhura uye anoda tsvakiridzo yakawanda nekuvandudzwa kuti ibudirire mukutengeserana. Kushanda zvakanaka kwekugadzira hydrogen kunofanirwawo kuvandudzwa, sezvo chikamu chidiki chezuva chinotorwa nealgae ndicho chinoshandurwa kuita hydrogen.
Kunyange zvakadaro, mukana wealgae kugadzira hydrogen haugone kufuratirwa. Iyi nzira itsva inogona kuita basa guru mukuchinja chikamu chesimba sezvo kudiwa kwesimba rakachena, rinogona kuvandudzwa pasi rose kuri kuramba kuchiwedzera. Kudyara mari mukutsvaga nekuvandudza, pamwe chete nehurongwa hwehurumende hunotsigira, zvinogona kukurumidzisa kutengeserana kwetekinoroji iyi. Kugadzira nzira dzinoshanda uye dzisingadhuri dzekurima algae, kubvisa hydrogen, uye kuichengeta kunogonawo kuvhura nzira yekuti tekinoroji iyi ishandiswe zvakanyanya.
Mukupedzisa, kugadzirwa kwehydrogen kubva mualgae inzira inovimbisa yekugadzira simba rinogara kwenguva refu. Inopa simba rakachena, rinogona kuvandudzwa rinogona kubatsira kuderedza kukanganisa kwenzira dzemazuva ano dzekugadzira simba. Kunyange hazvo matambudziko achiripo, mukana wekuti tekinoroji iyi ishandure indasitiri yesimba wakakura. Nekutsvaga nekuvandudza kuri kuenderera mberi, kugadzirwa kwehydrogen kubva mualgae kunogona kuve chinhu chakakosha mukusanganiswa kwesimba repasi rose, zvichiunza nguva itsva yekugadzira simba rinogara kwenguva refu uye risingakuvadzi nharaunda.
