Ukuvunywa kwe-Fire marshal kugubungela iinkqubo zokucima umlilo. Izivumelwano zoqhagamshelwano zichaza iimfuno zokhuseleko lwegridi.
Ingaba igridi{0}}inokulinganisa ugcino lwamandla ebhetri ngokukhawuleza kangakanani kuphazamiseko lwegridi?
Iibhetri zeLithium-ziphendula ngemilliseconds ukuya kwi{1}}yamaxesha amisiweyo okwesibini. Inkqubo ye-Hornsdale ifakwe amandla ngaphakathi kwee-milliseconds ngexesha lokusilela kwejeneretha yeLoy Yang. Oku kuphumelela kakhulu ukodlula isizukulwana esiqhelekileyo esifuna 6-imizuzwana eyi-10. Iibhetri ezihambayo ziphendula ngemizuzu nje eqhelekileyo. Iinkqubo ze-lead-asidi ziwela phakathi kwezi zinto zigqithisayo kwimizuzwana ukuya kwimizuzu. Ixesha lokuphendula ngokukhawuleza lenza ingeniso yeprimiyamu evela kwiimarike zolawulo lwamaxesha.
Kwenzeka ntoni kwiibhetri zegridi ekupheleni kobomi?
Iibhetri zeLithium-zigcina ama-70-80% amandla xa erhola kwinkonzo yegridi. Uninzi lufumana usetyenziso lwesibini{9}lobomi kwiindima ezingabalulekanga kangako. Iziseko ezingundoqo zokurisayikilisha ziyaphuhla ngeenkampani ezifana neRedwood Materials ezifumana kwakhona i-95%+ yemathiriyeli. Ii-electrolyte zebhetri eziqukuqelayo zinokuphinda zisetyenziswe ngokungenasiphelo. I-lead-iasidi iseke iziseko zophuhliso lokurisayikilisha nge-99% yamazinga okubuyisela kwiimarike eziphuhlileyo. Isiphelo esifanelekileyo{13} socwangciso-bomi ngexesha lophuhliso lweprojekthi siqinisekisa ukulahlwa okunenkathalo okanye uhlengahlengiso.
Ngaba igridi{0}}isikali seenkqubo zokugcina amandla ebhetri zisebenza ngamandla ahlaziyekayo?
Igridi-isikali sogcino lwamandla ebhetri lwenza ukuba kungene uhlaziyo oluphezulu. Iibhetri zigcina ukuveliswa kwesola kunye nomoya ogqithisileyo ukuze zisetyenziswe kamva. Bagudisa ukuguquguquka kwemveliso ecela umngeni uzinzo lwegridi. Ngaphezulu kwe-75% yebhetri ye-US efakwe kwi-2022-2025 ebekwe kwiindawo ezinokuhlaziywa okuphezulu okunokuhlaziywa. Itekhnoloji ivumela abaqhubi begridi ukuba bagcine ukuthembeka ngelixa bedibanisa imithombo yokuvelisa eguquguqukayo.
Iingcebiso zokugqibela
Itekhnoloji yeLithium-yokusebenza kwigridi{1}}yesiseko sogcino lwamandla ebhetri usetyenziso ngo-2025. Iindleko ziyehla, ukusebenza okuqinisekisiweyo, kunye nempendulo ekhawulezayo iyenza ibe lukhetho oluhlala lukhona. Iiprojekthi ezifuna i-2-iiyure ezi-6 zogcino kunye nokuhamba ngebhayisikile rhoqo kufuneka zikhethe i-lithium-ion.
Iibhetri eziqukuqelayo zifuna ukuthathelwa ingqalelo ixesha elide-usetyenziso oludlula iiyure eziyi-8-10. Iiprojekthi ezigxininisa ubomi be-asethi yeminyaka engama-20-30 zinokuthethelela iindleko eziphezulu zangaphambili. Vavanya uqoqosho lomjikelo wobomi buphelele kuneendleko ezinkulu nje.
Ilead{{0}iasidi iyavakala kuphela kwiimeko ezilinganiselweyo. Usetyenziso lwamandla ogcino kunye nokukhwela ibhayisekile okungaqhelekanga kuhlala kusebenza. Uhlahlo-lwabiwo mali-iiprojekthi ezithintelweyo kwiimarike eziphuhlayo zisenokusebenzisa iteknoloji. Nangona kunjalo, ukuhla kwe-lithium -kuxabisa iindleko ze-ion nezi zicelo.
Gxininisa kwiindleko zizonke zobunini kunexabiso lokuqala. Bala ingeniso evela kwiinkonzo ezininzi zegridi. Tshatisa amandla etekhnoloji kwiimfuno zakho zokusebenza ezithile. Ukhetho oluchanekileyo luxhomekeke kwindibaniselwano yakho eyodwa yeemfuno zexesha, amaxesha okukhwela ibhayisikile, amathuba engeniso, kunye neemeko zesayithi.
