Yiluphi uhlelo olungcono kakhulu lokugcina amandla?

Kukhiqizwa isihloko. Kuqediwe!

Uma kukhulunywa ngokugcinwa kwamandla, kunezinketho ezahlukahlukene ezitholakalayo, ngayinye inezinzuzo zayo kanye nokungalungi kwayo. Kusukela kumabhethri endabuko kuya kubuchwepheshe obuthuthukisiwe njengesitoreji samanzi esipompiwe, ukusesha uhlelo lokugcina amandla olungcono kakhulu kuyaqhubeka. Kulesi sihloko, sizohlola ezinye zezinhlelo zokugcina amandla ezidumile kakhulu, amakhono azo, kanye nezinhlelo zazo ezingaba khona.

Indima Yokugcina Amandla

Ukugcinwa kwamandla kudlala indima ebalulekile ezinhlelweni zamandla zesimanje, okuvumela ukuhlanganiswa okuthembekile nokuphumelelayo kwemithombo yamandla avuselelekayo njengamandla elanga nawomoya. Ngokwesiko, ukugcinwa kwamandla kuye kwasetshenziswa ukulinganisela ukunikezwa kanye nesidingo kanye nokuhlinzeka ngamandla okusekelayo ngesikhathi sokungasebenzi. Kodwa-ke, ngokungena okwandayo kwemithombo yamandla avuselelekayo ngezikhathi ezithile, isidingo sokugcina amandla sikhule kakhulu. Izinhlelo zokugcina amandla zingasiza ekunciphiseni ukuguquguquka kokukhiqizwa kwamandla avuselelekayo futhi zinikeze ukunikezwa kwamandla okuzinzile lapho ilanga lingakhanyi noma umoya ungavunguzi.

Ukugcinwa kwamandla nakho kudlala indima ebalulekile ekufakweni kukagesi kwezokuthutha, okuvumela ukusetshenziswa kabanzi kwezimoto zikagesi kanye nokunciphisa ukuthembela kumafutha emvelo. Njengoba isidingo semithombo yamandla ehlanzekile futhi eqhubekayo siqhubeka nokukhula, ukuthola uhlelo lokugcina amandla olungcono kakhulu kuba yinto ebalulekile ekushintsheleni ekusaseni lamandla eliqhubekayo.

Izinhlelo Zokugcina Amabhethri

Izinhlelo zokugcina amabhethri bezilokhu ziwubuchwepheshe bokugcina amandla obusetshenziswa kakhulu kuze kube manje, ngenxa yezindleko zazo eziphansi, ukusebenza kahle okuphezulu, kanye nokuguquguquka. Amabhethri aphinde ashajwe, njenge-lithium-ion, i-lead-acid, kanye namabhethri okugeleza, avame ukusetshenziswa ezinhlelweni zokugcina amandla ezilinganisweni zegridi kanye nezinhlelo zokugcina amandla ezisatshalaliswayo.

Amabhethri e-lithium-ion, ikakhulukazi, abone intuthuko enkulu eminyakeni yamuva nje, ngenxa yobuningi bawo bamandla aphezulu kanye nezindleko ezinciphile. Lawa mabhethri asetshenziswa kabanzi ezimotweni zikagesi nasezinhlelweni zokugcina amandla zokuhlala. Kodwa-ke, ukukhathazeka ngokuntuleka kwezinto, ukuphepha, kanye nokuphila komjikelezo okulinganiselwe kuphakamise imibuzo mayelana nokusimama kwesikhathi eside kwamabhethri e-lithium-ion.

Ngakolunye uhlangothi, amabhethri e-lead-acid abe ubuchwepheshe obuvelele bokugcina amandla amashumi eminyaka, ngenxa yokuthembeka kwawo kanye nezindleko eziphansi. Lawa mabhethri avame ukusetshenziswa ezinhlelweni zamandla ezisekelayo kanye nezinhlelo zokusebenza ezingaphandle kwegridi. Kodwa-ke, ubuningi bawo bamandla obuphansi kanye nempilo yomjikelezo elinganiselwe kuwenza angafaneleki kangako ezixazululweni zokugcina amandla zesikhathi eside.

Amabhethri okugeleza, njenge-vanadium redox namabhethri e-zinc-bromine, angobunye ubuchwepheshe bokugcina amandla obuthembisayo obunikeza ukuguquguquka okuphezulu kanye nokuphila isikhathi eside. Lawa mabhethri asebenzisa ama-electrolyte aketshezi ukugcina amandla, okwenza afanelekele ukusetshenziswa kokugcina isikhathi eside. Kodwa-ke, ubuningi bawo bamandla obuphansi kanye nomklamo wesistimu oyinkimbinkimbi kuye kwavimbela ukwamukelwa kwawo kabanzi.

Isitoreji Samanzi Esipompiwe

Isitoreji samanzi esipompiwe singenye yezindlela zokugcina amandla ezindala kakhulu neziqinisekisiwe kakhulu, ezinokufakwa okukhulu emhlabeni jikelele. Lolu hlelo lusebenzisa amandla asele ukupompa amanzi kusuka edamini eliphansi kuya edamini eliphezulu ngezikhathi zokudingeka okuphansi. Uma kudingeka amandla, amanzi akhishwa abuyele edamini eliphansi ngama-turbine, akhiqize ugesi.

Isitoreji samanzi esipompiwe sinikeza ukusebenza kahle okuphezulu, impilo yomjikelezo omude, kanye nekhono lokugcina amandla isikhathi eside. Futhi ubuchwepheshe obuvuthiwe obunomlando oqinisekisiwe wokuthembeka nokusebenza. Kodwa-ke, izindleko eziphezulu kusengaphambili, ukutholakala okulinganiselwe kwezindawo ezifanele, kanye nomthelela emvelweni kuye kwanciphisa ukuthunyelwa kabanzi kwesitoreji samanzi esipompiwe.

Naphezu kwezinselelo zayo, isitoreji samanzi esipompiwe sisalokhu siyigugu lokuqina kwegridi kanye nokuhlanganiswa kwamandla avuselelekayo, ikakhulukazi ezindaweni ezinemithombo yamanzi eminingi kanye nokwehlukahluka okukhulu kwesidingo samandla.

Isitoreji Samandla Omoya Ocindezelwe

Isitoreji samandla omoya ocindezelwe (i-CAES) ubuchwepheshe obuthembisayo bokugcina amandla obusebenzisa ugesi owengeziwe ukucindezela umoya nokuwugcina emihumeni engaphansi komhlaba noma emikhunjini ecindezelwe. Uma kudingeka amandla, umoya ocindezelwe uyakhululwa futhi wandiswe ngama-turbine ukuze kukhiqizwe ugesi.

I-CAES inikeza ukusabalala okuphezulu, impilo yomjikelezo omude, kanye nethuba lokugcina isitoreji isikhathi eside ngezindleko eziphansi. Ingahlanganiswa futhi nengqalasizinda yegesi ekhona, njengemipayipi yegesi yemvelo, ukuthuthukisa ukuguquguquka nokuqina kohlelo lwamandla. Kodwa-ke, isidingo sokwakheka kwe-geological okufanele, ukulahlekelwa kwamandla ngesikhathi sokucindezelwa nokwandiswa, kanye nokukhathazeka ngezemvelo kuye kwaba yinselele ekwamukelweni kabanzi kwe-CAES.

Intuthuko kwezobuchwepheshe be-CAES obungashisi kakhulu kanye nobe-adiabatic ihlose ukuthuthukisa ukusebenza kahle kanye nomthelela wemvelo wokugcina amandla omoya ocindezelwe, okwenza kube inketho ekhangayo kakhulu yezinhlelo zokusebenza zokugcina amandla ezinkulu.

Izinhlelo Zokugcina I-Hydrogen

I-hydrogen ithole ukunakwa njengendlela yokuthwala amandla kanye nendawo yokugcina amandla isikhathi eside kanye nomthamo ophezulu. Izinhlelo zokugcina i-hydrogen zisebenzisa ugesi owengeziwe ukwenza amanzi abe yi-electrolyze futhi akhiqize i-hydrogen, engagcinwa bese kamuva iguqulwa ibe ugesi ngamaseli kaphethiloli noma izinjini zokushisa.

I-hydrogen inikeza amandla amaningi, ikhono lokugcina isikhathi eside, kanye nokuguquguquka kokusetshenziswa ezinhlotsheni ezahlukene zokusebenza, okuhlanganisa ezokuthutha, izinqubo zezimboni, kanye nokukhiqizwa kwamandla. Ingasebenza futhi njengendlela yokugcina nokuthutha amandla avuselelekayo amabanga amade, ukunqoba izinselele zokuguquguquka kwesifunda kanye nokuminyana kwegridi.

Kodwa-ke, ukukhiqizwa, ukugcinwa, kanye nokusetshenziswa kwe-hydrogen kuhlinzeka ngezinselele zobuchwepheshe nezomnotho, okuhlanganisa ukulahlekelwa amandla ngesikhathi se-electrolysis, i-hydrogen embrittlement, kanye nezindleko zengqalasizinda. Naphezu kwalezi zinselele, izinhlelo zokugcina i-hydrogen zinamandla amakhulu okusekela ukushintshela ohlelweni lwamandla olunekhabhoni ephansi futhi zinegalelo ekuphepheni kwamandla kanye nokuqina.

Isiphetho

Ekuphetheni, ukusesha uhlelo lokugcina amandla olungcono kakhulu kuyaqhubeka nokukhula njengoba isidingo sezixazululo zamandla ezihlanzekile nezisimeme sikhula. Amabhethri, isitoreji samanzi esipompiwe, isitoreji samandla omoya ocindezelwe, kanye nezinhlelo zokugcina i-hydrogen konke kunikeza amakhono ahlukile futhi kungadlala indima ebalulekile ekuhlanganiseni imithombo yamandla avuselelekayo, ukuthuthukisa ukuzinza kwegridi, kanye nokusekela ukufakwa kukagesi kwezokuthutha.

Uhlelo ngalunye lokugcina amandla lunezinzuzo kanye nemikhawulo yalo, futhi ukukhetha uhlelo olungcono kakhulu kuncike ezintweni ezahlukahlukene, okuhlanganisa izindleko, ukusabalalisa, ukusebenza kahle, umthelela wemvelo, kanye nezinhlelo zokusebenza ezithile. Njengoba ubuchwepheshe buqhubeka buthuthuka futhi isidingo sokugcina amandla sikhula, kubalulekile ukuhlola nokuthuthukisa ubuchwepheshe obuhlukahlukene bokugcina amandla ukuze kuhlangatshezwane nezidingo zendawo yamandla eshintsha ngokushesha.
