I-Nissan iphuhlisa imoto yokuqala yehlabathi eqhutywa ziiseli eziqinileyo zeoksidi.
Kwixesha elizayo, yeyiphi itekhnoloji yokuqhubela phambili eya kusetyenziswa ziimoto? Ngomnye wemibuzo (emininzi!) engaphendulekiyo ebisoloko ixakene neshishini leemoto. Ukwazi ukuba ii-injini zokutsha zangaphakathi zineentsuku zabo zibaliwe, ii-brand ziye zatyala amakhulu ezigidi zee-euro ekuphuhliseni ezinye izisombululo, ukusuka kwi-100% yeemoto zombane ezinebhetri ukuya kwabanye, kunye ne-100% yombane, kodwa i-fuel cell cell ye-hydrogen. Nangona kunjalo, ezi zicombululo zimbini zineengxaki ezithile.
Kwimeko yeemoto zombane, kukuzimela kweebhetri kunye namaxesha okutshaja okwenze ukuba kube nzima ukuphumeza esi sisombululo kwinqanaba elikhulu. Kwimeko yeenqwelo ze-hydrogen fuel cell (ezifana neToyota Mirai) ingxaki inxulumene ne: 1) ukusetyenziswa okunyanzelekileyo kweetanki zoxinzelelo oluphezulu ngenxa yokuguquguquka kwe-hydrogen; 2) ifuna ukuphuhliswa kwenethiwekhi yokusabalalisa ukusuka ekuqaleni kwaye; 3) iindleko ze-hydrogen processing.
Ngoko ke sithini isisombululo sikaNissan?
Isisombululo sikaNissan sibizwa ngokuba yiSolid Oxide Fuel Cell (SOFC) kwaye isebenzisa i-bio-ethanol njengamafutha. Ingenelo? Ngokungafaniyo ne-hydrogen, le mafutha ayifuni iitanki zoxinzelelo oluphezulu okanye izitishi ezikhethekileyo zokuzalisa. I-SOFC (i-Solide Oxyde Fuel-Cell) yiseli ye-fuel esebenzisa ukuphendulwa kwamafutha amaninzi, kuquka i-ethanol kunye negesi yendalo, kunye ne-oksijini emoyeni ukuvelisa umbane ngokusebenza okuphezulu.Ingaba isebenza kanjani?
I-e-Bio fuel cell ivelisa umbane nge-SOFC (ijenereyitha yombane) isebenzisa i-bioethanol egcinwe kwisithuthi kwaye isebenzisa i-hydrogen ekhutshwe kuloo mafutha ngokusebenzisa i-reformer kunye ne-atmospheric oxygen, kunye ne-electrochemical reaction elandelayo ivelisa umbane ukunika amandla isithuthi. Ngokungafani neenkqubo eziqhelekileyo, i-e-Bio i-fuel cell ine-SOFC (i-Solide Oxyde Fuel-Cell) njengomthombo wamandla, ngaloo ndlela ivumela amandla amakhulu okusebenza okuvumela ukuba isithuthi sifumane ukuzimela okufana neenqwelo ze-petroli (ngaphezu kwe-600km).
Ukongezelela, iimpawu zokuqhuba zombane eziye zanikwa amandla yimoto ene-e-Bio fuel cell - kubandakanywa ukuqhuba okuthe cwaka, isiqalo somgca kunye nokukhawuleza ngokukhawuleza - kuvumela abasebenzisi ukuba banandiphe induduzo ye-100% yemoto yombane (VE).
Kwaye i-bio ethanol, ivela phi?
Amafutha e-bio ethanol, kuquka nalawo aveliswa kummoba kunye nombona, afumaneka ngobuninzi kumazwe aseAsia nakuMntla noMzantsi Melika. kwimveliso yamandla engingqi, exhaswa ziziseko ezingundoqo ezikhoyo. Ngenkqubo ye-bio-ethanol, ukukhutshwa kwe-CO2 kungathathi hlangothi ekubeni inkqubo yokukhula kommoba, apho i-biofuel iveliswa, ivumela "i-Carbon Neutral Cycle" ukuba ifunyanwe, ngokungekho ukwanda kwe-CO2.Kwaye iindleko, ziya kuba phezulu?
Ngethamsanqa hayi. Iindleko zokusebenzisa olu hlobo lwesithuthi ziya kufana nezo ze-EV zangoku. Ngexesha lokunciphisa i-refueling kunye namandla amakhulu okuvelisa umbane, le teknoloji iya kuba yinto efanelekileyo kubasebenzisi abafuna ukuzimela okuphezulu kunye namandla, ngaloo ndlela bakwazi ukuxhasa iintlobo ezahlukeneyo zeenkonzo, ezifana nokusabalalisa okukhulu.
Bubuhle bezinto ezintsha kwi "imo ecocekileyo". Xa isiqingatha sehlabathi sasicinga ukuba eli shishini liza kulandela indlela ethile, libhengeza i-hydrogen njengamafutha exesha elizayo, kwavela iteknoloji entsha ekwaziyo ukubeka yonke into ethandabuzekayo. Amaxesha amnandi aseza.
