Vanadium Energy Storage - 2

Kupomba uye kuchengetedza simba kune zvakakwirira zvinodikanwa zvenzvimbo yenzvimbo. Inowanzovakwa mumadhamu uye dzimwe nzvimbo, iyo isingakodzeri mamiriro ose ezvinhu. Pamberi pehukuru-hukuru hwekuchengetera magetsi (senge grid yekubatanidza) kana mamiriro evatengi (senge mota nyowani dzemagetsi), tekinoroji yekuchengetedza simba remagetsi inogona kuve yekuwedzera yakanaka.

Electrochemical energy kuchengetedza tekinoroji yakafambira mberi nekukurumidza mumakore achangopfuura. Simba reVanadium, serimwe rematavi aro, rine maitiro ekuchengetedza kwezvakatipoteredza, hapana kusvibiswa, hupenyu hurefu hwebasa, hukuru hwekushandura (kusvika ku65% - 80%), kushanda kwakagadzikana uye yakakwirira-frequency inodzokororwa kuchaja. Inokodzera mhepo uye solar kuchengetedza simba uye yave "hombe yekuchaja pfuma" yemagetsi grid.

Kana lithium bhatiri ikozvino yave yakanyatsokodzera "Mambo" wemusika wekuchengetedza simba, saka vanadium bhatiri inyeredzi nyowani munzvimbo yehukuru-hukuru yekuchengetedza simba.

Yese vanadium inoyerera bhatiri tekinoroji yakaiswa pamberi muna 1985, uye Europe, America, Japan nedzimwe nyika dziri pamberi pekutengesa. Pakatanga 2000, vanadium mabhatiri masisitimu munyika idzi akange amboshandiswa mukuveura kwepamusoro kwezviteshi zvemagetsi, kuchengetedza simba rezuva, kuchengetedza kwesimba remhepo uye zvimwe zviitiko, padyo nedanho rekutengesa.

Pasi pemashure e "double carbon" (carbon neutralization uye carbon peak), photovoltaic nemamwe maindasitiri ane mutoro wekugadzira magetsi asvika kumberi kwepasi, uye yakatevera yekuchengetera simba indasitiri yave nhandare yehondo yevanyanzvi.

Chekutanga pane zvese, sirogani yekushambadzira ndeye lithium bhatiri. Motokari itsva dzemagetsi dzinotyaira kuderera kunoramba kuripo kwemutengo welithium bhatiri, kuitira kuti lithium bhatiri rigone kuiswa kune simba rekuchengetedza pamwero mukuru uye ive mutsara mukuru parizvino.

Gwaro iri riri kuteverawo nekukasika. Zvinoenderana nechirongwa chemakore gumi nemana chekuchengetedza simba, zvakarongwa kuti zvizadzise kuvandudzwa kwakatarisana nemusika kwekuchengetedza simba idzva panosvika 2030. Zvinofungidzirwa kuti panosvika 2025, iyo nyowani yakaiswa yelithium bhatiri simba rekuchengetedza inotarisirwa kusvika 64.1gwh, ine huwandu hwekukura kwe87% mumakore mashanu anotevera.

Asi lithium mabhatiri haana kukwana. Kumusoro, maChina eLithium zviwanikwa haana kupfuma uye anonyanya kuvimba nekutenga kunze kwenyika. Iko kudiwa kukuru kwakaunzwa nekabhoni kaviri kwakasimudza mutengo zvishoma nezvishoma. Kubva gore rapfuura, mutengo we lithium kumusoro kwerwizi wakakwira kusvika pakakwirira-nguva. Munzvimbo dzakakura dzekuchengetedza simba, lithium bhatiri zvikumbiro zvakavewo netsaona dzakawanda, uye kuchengetedzwa kwayo kunoda kuongororwa.

Naizvozvo, mamwe matekinoroji matsva anodiwa kuwedzera akasiyana ekuchengetedza simba mamiriro. Pane chiratidzo chakajeka muchirongwa chekuchengetedza simba chechirongwa che14 chemakore mashanu, chichangobva kuvhurwa - chinangwa chega chega ndechekuderedza mutengo wemagetsi emagetsi ekuchengetedza ne30%. Uye zvakare, kusiyana nekusimbisa kwekutanga pane lithium mabhatiri, iyo mutemo inonongedza "kuvandudzwa kweakasiyana emagetsi ekuchengetedza simba tekinoroji"
