IShayina ifinyelele ingqophamlando enkulu kuisitoreji samandla esikalini segridingokuqedwa kwesakhiwo esikhulu kunazo zonke emhlabeniibhethri lokugeleza kwe-vanadium redox (VRFB)iphrojekthi. Itholakala eJimusar County, eXinjiang, lo msebenzi omkhulu, oholwa yiChina Huaneng Group, uhlanganisa uhlelo lwebhethri lwe-VRFB olunamandla angu-200 MW / 1 GWh kanye nepulazi elikhulu lamandla elanga elingu-1 GW.
Imele ukutshalwa kwezimali kwe-CNY 3.8 billion (cishe amaRandi ayizigidi ezingu-520), lo msebenzi usabalala kumahektha angu-1,870. Uma ususebenza ngokugcwele, kulindeleke ukuthi ukhiqize ugesi ohlanzekile ongu-1.72 TWh minyaka yonke, okunegalelo ekunciphiseni okukhulu kwamathani angaphezu kwezigidi ezingu-1.6 okukhishwa kwe-CO₂ ngonyaka.
Umsebenzi oyinhloko walokhu kufakwa kwe-VRFB ukubhekana nokuphazamiseka okungokwemvelo kwe-amandla elanga. Yakhelwe amahora amahlanu okukhishwa okuqhubekayo, isebenza njengesivikelo esibalulekile kanye nesiqinisi segridi yendawo. Leli khono libaluleke kakhulu eXinjiang ecebile ngezinsizakusebenza, lapho amandla amaningi elanga nomoya aye abhekana nezinselele emlandweni ezivela ekuncishisweni nasekuncishisweni kokudluliselwa kwamandla kagesi.
1. Ukwanda Kwezinto Zokugcina Izinto Nobuchwepheshe Obuhambisanayo
Ubukhulu balo msebenzi wesistimu yebhethri yokugeleza kwe-VRFB redox bugcizelela ukuphuthuma komhlaba wonke kwezixazululo ezinkulu zokugcina amandla zesikhathi eside ukuze kuhlanganiswe amandla avuselelekayo ngempumelelo. Nakuba ubuchwepheshe bebhethri be-VRFB buhamba phambili ezinhlelweni zokusebenza ezidinga impilo yomjikelezo omude kakhulu, ukuphepha ngamanani amakhulu e-electrolyte, kanye nokuwohloka okuncane eminyakeni eminingi edlule, obunye ubuchwepheshe obufanaAmabhethri e-Lithium Iron Phosphate (LFP)ziyizikhungo zamandla ezigabeni ezahlukene.
IUhlelo lwebhethri le-LFP, njengalezo esizikhethele zona, zinikeza izinzuzo ezihlukile:
- ⭐Ubuningi Bamandla Aphezulu: Inikeza amandla engeziwe endaweni encane, ilungele ukufakwa okuncishisiwe isikhala.
- ⭐Ukusebenza Kahle Kakhulu Kokuhamba Nokujika: Ukunciphisa ukulahleka kwamandla ngesikhathi sokujikeleza kokushaja/ukukhipha amandla.
- ⭐ Ukuphepha Okuqinisekisiwe:Idume ngokuqina okumangalisayo kokushisa kanye namakhemikhali.
- ⭐ Izindleko Ezingcono Zokugibela Ibhayisikili Nsuku Zonke: Isebenza kahle kakhulu ekusetshenzisweni kwansuku zonke kokushaja/ukukhipha igesi njengokushefa okuphezulu kanye nokulawula imvamisa.
2. Ubuchwepheshe Bokuhlanganisa Igridi Ezinzile
Ama-VRFB kanyeIsitoreji sebhethri se-LFPngokuvamile ziyahambisana, hhayi izimbangi eziqondile. I-VRFB ifaneleka kahle kakhulu endaweni yokugcina isikhathi eside kakhulu (amahora angaphezu kwangu-4, mhlawumbe izinsuku) kanye namaphrojekthi lapho impilo ende yamashumi eminyaka ibaluleke kakhulu. I-LFP ikhanya kakhulu ekusetshenzisweni okudinga amandla amaningi, impendulo esheshayo, kanye nokusebenza kahle kakhulu kokujikeleza kwansuku zonke (ngokuvamile isikhathi samahora angu-2-4). Ndawonye, lezi zixazululo zokugcina amandla ezahlukahlukene zakha umgogodla wegridi enamandla avuselelekayo, aqinile.
Iphrojekthi enkulu ye-VRFB yaseShayina iyisibonakaliso esicacile: isitoreji esikhulu, esihlala isikhathi eside asiseyona umqondo, kodwa siyiqiniso elibalulekile lokusebenza. Njengoba isidingo sokuzinza kwegridi kanye nokuhlanganiswa okuvuselelwayo sikhula emhlabeni jikelele, ukuthunyelwa kwe-VRFB kanye ne-AdvancedIbhethri le-LFPizinhlelo zizoba ezibalulekile ukuze kube nekusasa lamandla azinzile.
