I-China izuze ingqopha-mlando enkulu kuisitoreji samandla esikalini segridingokuphothulwa kwenkulu kunazo zonke emhlabenii-vanadium redox flow battery (VRFB)iphrojekthi. Itholakala esiFundazweni saseJimusar, eXinjiang, lo msebenzi omkhulukazi, oholwa yi-China Huaneng Group, uhlanganisa uhlelo lwebhethri engu-200 MW / 1 GWh VRFB nepulazi elikhulu lelanga eliyi-GW elingu-1.
Imele ukutshalwa kwezimali kwe-CNY 3.8 billion (cishe amaRandi ayizigidi ezingama-520), iphrojekthi isakazeka kumahektha ayi-1,870. Uma isisebenza ngokugcwele, kulindeleke ukuthi ikhiqize ugesi ohlanzekile ongu-1.72 TWh obalulekile minyaka yonke, okunomthelela ekwehlisweni okukhulu kwamathani angaphezu kwezigidi ezingu-1.6 ze-CO₂ ngonyaka.
Umsebenzi oyinhloko walokhu kufakwa kwe-VRFB ukubhekana nokuphazamiseka okungokwemvelo kweamandla elanga. Idizayinelwe amahora amahlanu okukhipha okuqhubekayo, isebenza njengesigcinalwazi esibalulekile nesiqinisi kugridi yasendaweni. Leli khono libaluleke kakhulu ku-Xinjiang enothe ngezinsiza, lapho amandla amaningi elanga nomoya aye abhekana nezinselelo ngokomlando ezivela ekunciphiseni nasekudluliseni imikhawulo.
1. Ukunyuka Kwesitoreji Nobuchwepheshe Bokuhambisana
Isilinganiso sale phrojekthi yesistimu yebhethri ye-VRFB redox igcizelela ukuphuthuma komhlaba wonke kwezixazululo ezinkulu, zesikhathi eside zokugcina amandla ukuze kuhlanganiswe okuvuselelekayo ngempumelelo. Nakuba ubuchwepheshe bebhethri ye-VRFB buhamba phambili ezinhlelweni ezidinga ukuphila komjikelezo omude kakhulu, ukuphepha ngamavolumu amakhulu e-electrolyte, kanye nokuwohloka okuncane phakathi namashumi eminyaka, obunye ubuchwepheshe obufana no.Amabhethri e-Lithium Iron Phosphate (LFP).kukhona amandla ezingxenyeni ezahlukene.
IUhlelo lwebhethri ye-LFP, njengalezo esisebenza kuzo ngokukhethekile, zinikeza izinzuzo ezihlukile:
- ⭐Ukuminyana kwamandla okuphezulu: Iletha amandla engeziwe endaweni encane, elungele ukufakwa okubambezeleke ngendawo.
- ⭐Ukusebenza Okuhle Kakhulu Kohambo Olujikelezayo: Ukunciphisa ukulahlekelwa kwamandla phakathi nemijikelezo yokushaja/yokukhipha.
- ⭐ Ukuphepha Okuqinisekisiwe:Idume ngokuzinza kwe-thermal namakhemikhali.
- ⭐ Ukusebenza Kwezindleko Zokuhamba Ngebhayisikili Nsuku Zonke: Isebenza kahle kakhulu ekushajelweni/kukhiphe izinhlelo zokusebenza zansuku zonke njengokushefa okuphezulu kanye nokulawula imvamisa.
2. Ubuchwepheshe Bokuhlanganisa Kwegridi Ezinzile
Ama-VRF kanyeIsitoreji sebhethri se-LFPzivame ukuphelelisana, hhayi izimbangi eziqondile. I-VRFB ifaneleka ngokufanelekile ukugcinwa isikhathi eside (amahora angu-4+, okungenzeka kube yizinsuku) namaphrojekthi lapho ubude bempilo amashumi eminyaka bubaluleke kakhulu. I-LFP ikhanya ezinhlelweni ezidinga ukuminyana kwamandla aphezulu, ukuphendula okusheshayo, nokusebenza kahle okuphezulu kokuhamba ngebhayisikili nsuku zonke (imvamisa ubude besikhathi samahora angu-2-4). Ndawonye, lezi zixazululo ezihlukahlukene zokugcina amandla zakha umgogodla wegridi eqinile, enamandla avuselelekayo.
Iphrojekthi yaseChina enkulukazi ye-VRFB iyisiginali ecacile: isitoreji esikhulu, esihlala isikhathi eside ayisewona umqondo, kodwa kuyiqiniso elibalulekile lokusebenza. Njengoba isidingo sokuzinza kwegridi nokuhlanganiswa okuvuselelekayo kukhula emhlabeni jikelele, ukuthunyelwa kwamasu kokubili kwe-VRFB nokuthuthukisiwe.Ibhethri ye-LFPizinhlelo zizobaluleka ngekusasa lamandla esimeme.
