Nei BMW yakatsiva iyo hydrogen injini nemafuta maseru?
Zviri mukati
BMW inoona hydrogen kunge tekinoroji inovimbisa muchikamu chikuru chemotokari uye ichagadzira iyo BMW X2022 ine mashoma maseru emafuta muna 5. Ruzivo urwu rwakasimbiswa nemutevedzeri wemutungamiri wekambani yeGerman yehydrogen matekinoroji, Dr. Jürgen Guldner.
Vazhinji vamwe vagadziri, vakaita saDaimler, nguva pfupi yadarika vakabvisa kushandiswa kwehydrogen mumotokari dzevapfuuri uye vari kungoisimudzira semhinduro yemarori nemabhazi.
Kubvunzana nevamiriri vekambani
Mumusangano wevhidhiyo venhau, vatapi venhau vanobva kumotokari dzino tungamira vakabvunza nhevedzano yemibvunzo nezve ramangwana reinjini dzehydrogen muchiratidzo chekambani. Heano mamwe emifungo yakauya mumusangano uyu wepamhepo wakaitwa pakutanga kwekugadzwa.
“Tinotenda mune kodzero yekusarudza,” anotsanangura kudaro Klaus Fröhlich, nhengo yeBMW Research Council. "Pakubvunzwa kuti rudzii rwekutyaira ruchadikanwa nhasi, hapana anogona kupa mhinduro yakafanana kumatunhu ese epasi ... Tinoda flexibility."
Sekureva kwaFröhlich, remangwana remota diki dzemuguta muEurope ndere mota dzemagetsi dzinofambiswa nebhatiri. Asi kune mahombe mamodheru, hydrogen ndiyo yakanaka mhinduro.
Kutanga hydrogen zviitiko
BMW yanga ichigadzira hydrogen drive kubvira 1979 neyekutanga 520h prototype uye ndokutanga mhando dzinoverengeka dzekuyedza muma1990.
Nekudaro, ivo vaishandisa mvura hydrogen yakadzvanywa mune yakasarudzika yemukati injini yemoto. Iyo kambani yakazoshandura zvakanyanya zano rayo uye, kubvira 2013, yave kugadzira hydrogen mafuta maseru mota (FCEV) yakabatana neToyota.
Sei wakachinja maitiro ako?
Sekureva kwaDr.Gouldner, pane zvikonzero zviviri zvekuongorora uku:
- Chekutanga, iyo yemvura hydrogen sisitimu ichine tsika yakaderera kushanda kweinjini dzinopisa mukati - chete 20-30%, nepo kushanda kwemafuta emafuta kunobva pa50 kusvika 60%.
- Chechipiri, mvura hydrogen yakaoma kuchengeta kwenguva yakareba uye inoda simba rakawanda kuitonhodza. Hydrogen gasi inoshandiswa mumasero emafuta pa 700 bar (70 MPa).
Iyo yemberi BMW i Hydrogen Inotevera ichave ne125 kW mafuta sero uye mota yemagetsi. Simba rese remotokari richava 374 simba rebhiza - rakaringana kuchengetedza kunakidzwa kwekutyaira kwakavimbiswa neiyo mhando.
Panguva imwecheteyo, huremu hwemota yesero yemafuta huchave hwakakwirira zvishoma pane huya huripo huripo hwema plug-in mahybrids (PHEV), asi pasi pehuremu hwemotokari izere yemagetsi (BEV).
Zvirongwa zvekugadzira
Muna 2022, mota iyi ichagadzirwa mune diki dzakateedzana uye haizotengeswe, asi inogona kupihwa kune vatengi kuti vaongororwe chaiko-nyika.
"Mamiriro ezvinhu akadai sezvivakwa uye kugadzirwa kwehydrogen haasati anyatsoenderana neakakura akateedzana,"akadaro Klaus Fröhlich. Mushure mezvose, yekutanga hydrogen kopi icharova nzvimbo dzekuratidzira muna 2025. Pakazosvika 2030, kambani yekambani inogona kunge iine akawanda emota dzakadai.
Dr. Gouldner vakagovana zvirongwa zvavo zvekuti zvivakwa zvinogona kukura nekukurumidza kupfuura zvaitarisirwa. Uchaida marori nemabhazi. Havagone kushandisa mabhatiri kudzikisa mweya. Rimwe dambudziko rakakomba rine chekuita nekugadzirwa kwehydrogen.
Pfungwa ye "hydrogen economy" inoenderana nekugadzirwa kwayo neelectrolysis kubva kunowanikwa patsva. Nekudaro, maitiro acho anoshandisa simba rakawanda - iyo yekugadzira unit yemahombe makuru eFCEV ngarava inogona kupfuudza ese aripo ezuva nemhepo simba muEurope.
Mutengo zvakare chinhu: Nhasi maitiro e electrolysis anodhura pakati pe $ 4 ne $ 6 pakirogiramu. Panguva imwecheteyo, hydrogen inowanikwa kubva kune gasi rechisikirwo neinonzi "shanduko yemhepo kuenda kune methane" inodhura ingangoita dhora pa kg. Nekudaro, mitengo inogona kudonha zvakanyanya mumakore anotevera, Gouldner akadaro.
"Paunenge uchishandisa hydrogen sehuni, pane kuraswa kwakakura kwesimba - kutanga unofanirwa kuigadzira kubva kumagetsi, wozoichengeta, woitakura uye woidzosera kuita magetsi," -anotsanangura mutevedzeri wemutungamiri weBMW.
“Asi kusaipira uku kune zvimwe zvakanakira. Hydrogen inogona kuchengetwa kwenguva yakareba, kwemwedzi yakati wandei, uye inogona kutakurwa zviri nyore uchishandisa kunyange chikamu chepombi dziripo. Haisi dambudziko kuitora munzvimbo dzine mamiriro esimba rinowanikwazve zvakanaka, seNorth Africa, uye kuipinza kuEurope kubva ikoko. "
