Esikhathini samandla avuselelekayo, ama-akhronimi amabili athola ukunakwa komhlaba wonke—i-BES (Izinhlelo Zesitoreji Samandla Ebhethri) kanye ne-ESS (Izinhlelo Zokugcina Amandla). Kokubili ubuchwepheshe obubalulekile obubumba kabusha indlela esenza ngayo, sigcine, futhi sisebenzisa amandla. Njengoba umhlaba uguqukela ezixazululweni zamandla esimeme, lezi zinhlelo ziya ngokuya ziduma, ikakhulukazi ezifundeni ezinokungena kwamandla avuselelekayo aphezulu. Kodwa yini ngempela i-BESS ne-ESS, futhi kungani zibona ukukhula okusheshayo okungaka?

Yini i-BESS ne-ESS?

Emgogodleni wabo, kokubili i-BESS ne-ESS zisebenzisa i- inhloso efanayo eyisisekelo: ukugcina amandla ukuze asetshenziswe esikhathini esizayo. Umehluko oyinhloko utholakala kububanzi bawo:

• I-BESS (Uhlelo Lwesitoreji Samandla Ebhethri): Lolu uhlobo oluthile lwesitoreji samandla esithembele kubuchwepheshe bebhethri, ngokuvamile i-lithium-ion, ukugcina ugesi. Amayunithi e-BESS avumelana nezimo kakhulu, ayakala, futhi afanelekela uhla olubanzi lwezinhlelo zokusebenza, kusukela ekusethweni kwezindawo zokuhlala kuya kumaphrojekthi amakhulu ezimboni.
• I-ESS (Uhlelo Lwesitoreji Samandla): I-ESS igama elibanzi elibhekisela kunoma iyiphi isistimu eklanyelwe ukugcina amandla. Nakuba i-BESS iwuhlobo olulodwa lwe-ESS, ezinye izinhlobo zifaka ukugcinwa komshini (njenge-hydro pumped noma ama-flywheels) kanye nesitoreji esishisayo (njengosawoti oncibilikisiwe). I-ESS ihlanganisa i-spectrum egcwele yobuchwepheshe bokugcina amandla obusiza ukulinganisela kokunikezwa kanye nesidingo.

Kungani I-BESS ne-ESS Ibalulekile?

Isimo samandla omhlaba sibhekene noshintsho olubalulekile njengoba amazwe emukela imithombo yamandla avuselelekayo njengelanga nomoya. Nakuba le mithombo yamandla ihlanzekile futhi iyinala, iphinde ibe nezikhawu—amaphaneli elanga awawakhiqizi amandla ebusuku, futhi izinjini zomoya zisebenza kuphela lapho kuvunguza umoya. Yilapho isitoreji samandla singena khona.

• Ukuzinza Kwegridi: I-BESS ne-ESS zinikeza isigcinalwazi segridi kagesi ngokugcina amandla amaningi akhiqizwa ngezikhathi zesidingo esiphansi futhi siwakhiphe lapho isidingo siphezulu noma lapho imithombo evuselelekayo ingawakhiqizi amandla. Lokhu kuqinisekisa ukutholakala kwamandla okuthembeke kakhudlwana futhi kuvimbela ukucisha noma ukunqamuka.
• Ukukhulisa Okuvuselelekayo: Ngaphandle kokugcinwa kwamandla, amandla amaningi avuselelekayo azomoshakala uma edlula isidingo esiphuthumayo. I-BESS ne-ESS zithwebula lokhu kusala, iqinisekisa ukuthi amandla ahlanzekile ayatholakala uma edingeka kakhulu.
• Ukunciphisa Ukukhishwa Kwekhabhoni: Ngokugcina amandla avuselelekayo, i-BESS kanye ne-ESS kunciphisa isidingo samandla ayisipele asuka ezitshalweni ezisekelwe kuphethiloli, okusiza ukwehlisa ukukhishwa kwekhabhoni futhi kuqhubekisele phambili imigomo yokusimama.
• Amandla Ukuzimela: Ezifundeni ezithembele kumafutha emvelo angenisiwe, ukugcinwa kwamandla kunikeza indlela eya ekuzimeleleni okukhulu kwamandla, ukunciphisa ukuthembela emithonjeni yangaphandle kanye nokuzinzisa izindleko zamandla.

Kungani I-BESS ne-ESS Izuza Ukuduma Ezifundeni Ezithize?

Izifunda ezimbalwa emhlabeni wonke zamukele ubuchwepheshe be-BESS kanye ne-ESS njengoba ziphishekela izinhloso zamandla avuselelekayo futhi zifuna ukuthuthukisa ukuqina kwegridi. Nakhu ukuthi kungani lezi zinhlelo ziba zibalulekile ezimakethe ezithile ezibalulekile:

1. I-Europe's Renewable Energy Push: I-Europe sekuyisikhathi eside ihola ekushintsheni kwamandla avuselelekayo, amazwe afana neJalimane, i-UK, ne-Spain etshala kakhulu amandla omoya namandla elanga. Ukuze kuhlanganiswe le mithombo yamandla ngezikhathi ezithile kugridi, i-Europe isiphendukele kubuchwepheshe be-BESS ne-ESS. Ukugcinwa kwebhethri kusiza ukulawula ukuguquguquka kokukhiqizwa kwamandla, ukuqinisekisa ukuzinza kwegridi nokunciphisa ukuthembela kumafutha ezinto ezimbiwa phansi.
2. Isidingo Esikhulayo SaseNyakatho Melika: E-United States nase-Canada, ukugcinwa kwamandla kuyadlondlobala njengoba izinsiza namabhizinisi befuna izindlela zokulinganisela isidingo samandla kanye nokuthuthukisa amandla egridi. I-California, ikakhulukazi, isiphenduke isizinda sokuqanjwa kabusha kokugcinwa kwamandla ngenxa yokuzibophezela kwayo kumandla avuselelekayo kanye nokunciphisa ukukhishwa kwekhabhoni.
3. I-Energy Transformation yase-Asia: Amazwe afana ne-China, Japan, ne-South Korea atshala imali eningi ekugcinweni kwamandla ukuze asekele imigomo yawo yamandla avuselelekayo. I-China, umkhiqizi omkhulu wamandla elanga nawomoya emhlabeni, ikhulisa ngokushesha umthamo wayo wokugcina amandla ukuze izinze igridi yayo yamandla futhi ihlangabezane nezinhloso zayo zokungathathi hlangothi kwekhabhoni ngo-2060.
4. Isidingo sase-Australia Sokuqina: Amabanga amakhulu ase-Australia nokuthembela kumandla avuselelekayo, ikakhulukazi ilanga, kwenze ukugcinwa kwamandla kwaba ingxenye ebalulekile yesu layo lamandla. Izifunda ezikude zezwe zivame ukubhekana nezinkinga zokusimama kwegridi, futhi izixazululo ze-BESS zibonise ukuthi ziyasebenza ekugcineni ukunikezwa kwamandla okuthembekile.

Ikusasa le-BESS ne-ESS

Njengoba izifunda eziningi emhlabeni wonke zisheshisa ukwamukela kwazo amandla avuselelekayo, isidingo sokugcinwa kwamandla okuthembekile sizoqhubeka nokukhula. Ubuchwepheshe bokugcina amandla buzodlala indima ebalulekile ekwehliseni izinyathelo zekhabhoni, kuthuthukiswe ukuvikeleka kwamandla, kanye nokwenza kube lula ukuguqukela kumandla ahlanzekile.

Kwa-Wenergy, sizibophezele ekuthuthukiseni nasekuletheni izixazululo ze-BESS ne-ESS ezisezingeni eliphezulu ezisiza amabhizinisi, izinsiza, kanye nohulumeni ukuthi balawule lolu shintsho lwamandla. Amasistimu ethu okugcina amandla angenziwa ngokwezifiso aklanyelwe ukuhlangabezana nezidingo ezithile zezimakethe ezihlukahlukene, ukuqinisekisa ukusebenza kahle okuphezulu kanye nokusimama kwesikhathi eside.

Isiphetho

I-BESS ne-ESS akusezona ubuchwepheshe be-niche—ziyingxenye yekusasa lamandla. Njengoba umhlaba uphokophele ekusaseni eliluhlaza, elisimeme, lezi zinhlelo zizoqhubeka nokubamba iqhaza elibalulekile ekulinganiseni ukuphakelwa kwamandla kanye nesidingo, ukuthuthukisa ukusetshenziswa kwamandla avuselelekayo, kanye nokuqhuba umfutho womhlaba wonke wokukhipha ikhabhoni.

Ngokubambisana ne-Wenergy, utshala imali ezixazululweni zokugcina amandla ezingagcini nje ngokunikeza izinzuzo ezisheshayo kodwa futhi ezifaka isandla ekusaseni elisimeme neliqinile lezizukulwane ezizayo.
