I-Vanadium Energy Storage - 2

Ukumpompa nokugcina amandla kunezidingo eziphezulu ngendawo yendawo. Ivamise ukwakhiwa kuma-reservoirs nakwezinye izindawo, okungafanelekile kuzo zonke izimo. Uma ubhekene nezimo ezinkulu zokugcina amandla (njengokuxhumeka kwegridi) noma izimo zabathengi (njengezimoto ezintsha zamandla), ubuchwepheshe bokugcina amandla e-electrochemical bungaba isengezo esihle.

Ubuchwepheshe bokugcina amandla e-Electrochemical buye benza intuthuko ngokushesha eminyakeni yamuva. Amandla e-Vanadium, njengelinye lamagatsha awo, anezici zokuvikela imvelo, akukho ukungcola, impilo ende yesevisi, ukusebenza kahle kokuguqulwa (kufika ku-65% - 80%), ukusebenza okuzinzile nokushaja okuphindaphindiwe kwe-high-frequency. Ifanele umoya kanye nesitoreji samandla elanga futhi isiphenduke "ingcebo enkulu yokushaja" yegridi yamandla.

Uma ibhethri ye-lithium manje isiyinkosi efaneleke kahle yemakethe yokugcina amandla, ibhethri ye-vanadium iyinkanyezi entsha endaweni yokugcina amandla amakhulu.

Bonke ubuchwepheshe bebhethri ye-vanadium flow babekwa phambili ngo-1985, futhi iYurophu, iMelika, iJapane namanye amazwe ahamba phambili kwezohwebo. Ekuqaleni kuka-2000, amasistimu ebhethri e-vanadium kulawa mazwe ayekade esetshenziswa ekushefweni okuphezulu kakhulu kweziteshi zikagesi, ukugcinwa kwamandla elanga, ukugcinwa kwamandla omoya kanye nezinye izimo, eduze nesiteji sokuhweba.

Ngaphansi kwesizinda "sekhabhoni ephindwe kabili" (i-carbon neutralization kanye ne-carbon peak), i-photovoltaic nezinye izimboni ezinomthwalo wemfanelo wokukhiqiza amandla zifinyelele phambili emhlabeni, futhi imboni yokugcina amandla eyalandela isiphenduke inkundla yempi elandelayo yabasomaqhinga.

Okokuqala, isiqubulo sokuthengisa ibhethri ye-lithium. Izimoto ezintsha zamandla zishayela ukwehla okuqhubekayo kwezindleko zebhethri ye-lithium, ukuze ibhethri ye-lithium isetshenziswe endaweni yokugcina amandla ngesilinganiso esikhulu futhi ibe umugqa ojwayelekile njengamanje.

Inqubomgomo nayo ilandela ngokushesha. Ngokohlelo lweminyaka eyi-14 lokugcinwa kwamandla, kuhlelwe ukuthi kufezeke intuthuko egxile emakethe yokugcinwa kwamandla amasha ngo-2030. Kulinganiselwa ukuthi ngo-2025, umthamo omusha ofakiwe wesitoreji samandla ebhethri ye-lithium kulindeleke ukuthi ufinyelele ku-64.1gwh, ngesilinganiso sokukhula esiyinhlanganisela esingu-87% eminyakeni emihlanu ezayo.

Kodwa amabhethri e-lithium awaphelele. Enhla nomfula, izinsiza ze-lithium zaseChina azicebile futhi zithembele kakhulu ekuthengeni kwamanye amazwe. Isidingo esikhulu esilethwe yi-double carbon siye sakhuphula inani kancane kancane. Kusukela ngonyaka odlule, intengo ye-lithium enhla nomfula ikhuphuke yafinyelela phezulu. Ezimweni ezinkulu zokugcina amandla, izinhlelo zokusebenza zebhethri ye-lithium nazo zibe nezingozi eziningi, futhi ukuphepha kwayo kudinga ukuhlolwa.

Ngakho-ke, obunye ubuchwepheshe obusha buyadingeka ukuze kwenezele izimo ezihlukene zokugcinwa kwamandla. Kukhona isignali esobala ohlelweni lokugcina amandla ohlelo lwe-14 lweminyaka emihlanu, olusanda kwethulwa - okuwukuphela komgomo wokulinganisa ukunciphisa izindleko zokugcina amandla e-electrochemical ngo-30%. Ngaphezu kwalokho, ngokungafani nokugcizelelwa kwangaphambilini kwamabhethri e-lithium, inqubomgomo ikhomba "ukuthuthukiswa kobuchwepheshe bokugcina amandla kagesi ahlukahlukene"
