UGcino lwaMandla eVanadium – 2

Ukumpompa kunye nokugcinwa kwamandla kuneemfuno eziphezulu zendawo yejografi. Ihlala yakhiwe kwiindawo zokugcina amanzi kunye nezinye iindawo, ezingafanelekanga kuzo zonke iimeko. Ekubhekaneni neemeko zokugcinwa kwamandla amakhulu (ezifana noxhumo lwegridi) okanye iimeko zabathengi (ezifana nezithuthi zamandla amatsha), iteknoloji yokugcina amandla e-electrochemical ingaba isongezelelo esihle.

Itekhnoloji yokugcina amandla e-Electrochemical yenze inkqubela ekhawulezileyo kwiminyaka yakutshanje. Amandla e-Vanadium, njengelinye lamasebe ayo, aneempawu zokukhuselwa kwendalo, akukho ngcoliseko, ubomi benkonzo ende, ukusebenza kakuhle kokuguqulwa (ukuya kuthi ga kwi-65% - 80%), ukusebenza okuzinzileyo kunye nokutshaja okuphindaphindiweyo okuphindaphindiweyo. Ilungele umoya kunye nokugcinwa kwamandla elanga kwaye ibe "yimpahla enkulu yokutshaja" yegridi yamandla.

Ukuba ibhetri ye-lithium ngoku ifanelekile "uKumkani" wemarike yokugcina amandla, ibhetri ye-vanadium yinkwenkwezi entsha kwindawo yokugcina amandla amakhulu.

Yonke iteknoloji yebhetri ye-vanadium flow ibekwe phambili kwi-1985, kwaye iYurophu, iMelika, iJapan kunye namanye amazwe ahamba phambili kwintengiso. Ekuqaleni kuka-2000, iinkqubo zebhetri ye-vanadium kula mazwe yayisele isetyenziswe ekuchebeni okuphezulu kwezikhululo zamandla, ukugcinwa kwamandla elanga, ukugcinwa kwamandla omoya kunye nezinye iimeko, kufutshane nenqanaba lokuthengisa.

Ngaphantsi kwemvelaphi "yekhabhoni ephindwe kabini" (i-carbon neutralization kunye ne-carbon peak), i-photovoltaic kunye namanye amashishini anoxanduva lokuvelisa amandla afikelele phambili kwihlabathi, kwaye imboniselo yokugcina amandla eyalandelayo iye yaba yindawo yokulwa elandelayo ye-strategists.

Okokuqala, isilogeni sorhwebo yibhetri ye-lithium. Izithuthi zamandla amatsha ziqhuba ukuhla okuqhubekayo kweendleko ze-lithium ibhetri, ukwenzela ukuba ibhetri ye-lithium ingasetyenziselwa ukugcinwa kwamandla kwinqanaba elikhulu kwaye ibe ngumgca oqhelekileyo okwangoku.

Lo mgaqo-nkqubo ukwalandela ngokukhawuleza. Ngokutsho kwesicwangciso se-14 seminyaka emihlanu yokugcinwa kwamandla, kucetywayo ukuqonda uphuhliso olubanzi olujoliswe kwiimarike zokugcina amandla amatsha ngo-2030. Kuqikelelwa ukuba ngo-2025, umthamo omtsha ofakiweyo wokugcinwa kwamandla ebhetri ye-lithium kulindeleke ukuba ufikelele kwi-64.1gwh, kunye nezinga lokukhula elihlanganisiweyo le-87% kwiminyaka emihlanu ezayo.

Kodwa iibhetri ze-lithium azifezekanga. Ekuphakameni, izibonelelo ze-lithium zaseChina azityebi kwaye zixhomekeke kwizinto ezithunyelwa ngaphandle. Imfuno enkulu eziswe yikhabhoni ephindwe kabini inyuse ixabiso ngokuthe ngcembe. Ukusukela kunyaka ophelileyo, ixabiso le-lithium kwindawo enyukayo liye lanyuka laya kutsho kwixesha eliphakamileyo. Kwiimeko ezinkulu zokugcina amandla, izicelo zebhetri ye-lithium nazo zineengozi ezininzi, kwaye ukhuseleko lwayo kufuneka luvavanywe.

Ke ngoko, obunye itekhnoloji entsha iyafuneka ukongeza iimeko ezahlukeneyo zokugcina amandla. Kukho uphawu olucacileyo kwisicwangciso sokugcinwa kwamandla kwisicwangciso se-14 seminyaka emihlanu, esandul 'ukutyhilwa - injongo yobuninzi kuphela kukunciphisa iindleko zokugcina amandla e-electrochemical ngama-30%. Ukongezelela, ngokungafaniyo nogxininiso lwangaphambili kwiibhetri ze-lithium, umgaqo-nkqubo ubonisa "uphuhliso lweteknoloji yokugcina amandla ombane"
