Nantsi into eyandothusayo xa ndandiqala ukuphanda abavelisi benkqubo yokugcina amandla ebhetri: abenzi nje iinguqulelo ezinkulu zeebhetri kwifowuni yakho. Benza imixokomelwano yendalo eyahlukileyo ngokupheleleyo{1}kwaye umsantsa phakathi kokubonayo upapashiweyo kwaye yintoni kanye emisela impumelelo ubanzi kunokuba abantu abaninzi becinga.
Abavelisi benkqubo yogcino lwamandla ebhetri (BESS) ziinkampani eziyila, zivelise, kwaye zisebenzisa{0}}iinkqubo ezinkulu zebhetri ukugcina amandla ombane ukuze asetyenziswe kamva. Ezi zixokelelwano ziqala kwiiyunithi zokuhlala ezigcina iikilowatts-iiyure ezimbalwa ukuya kwindawo eluncedo{3}}kufakelo lwesikali esikwazi ukunika amandla amakhulu amawaka ezindlu. Imakethi ifikelele kwi-25 yeebhiliyoni zeedola ngo-2024 kwaye kuqikelelwa ukuba iya kubetha i-114 yeebhiliyoni zeedola ngo-2032, ikhula phantse nge-20% ngonyaka.
Indlela Abavelisi beNkqubo yokuGcina iBattery eneneni eSebenzayo
Amanqaku amaninzi adibanisa bonke abavelisi be-BESS kudidi olunye. Kufana nokuthi i-Apple kunye nevenkile yokulungisa izinto ze-elektroniki zikwishishini elinye kuba bobabini basebenza ngeefowuni. Inyani yahlulahlulwe yangamanqanaba amathathu ahlukeneyo, kwaye ukuqonda oku kutshintsha yonke into malunga nokuvavanya ezi nkampani.
Inqanaba loku-1: Izigebenga eziDityanisiweyo (Iseli-ukuya-kwiNkqubo)I-CATL, BYD, kunye neTesla benza iiseli zabo zebhetri kwaye bazidibanise kwiinkqubo ezipheleleyo. I-CATL ithunyelwe nge-491 GWh ngo-2024-i-29% yokwanda ukusuka ngo-2023-kwaye yathatha i-38% yemarike yehlabathi. Ezi nkampani zilawula ikhonkco lexabiso elipheleleyo ukusuka kwimathiriyeli ekrwada ukuya kufakelo lokugqibela. Xa i-CATL ihambisa inkqubo, babheja kwikhemistri yeeseli zabo, inkqubo yabo yolawulo lwebhetri, kunye noyilo lwabo lokupholisa bonke abasebenza kwikonsathi.
I-BYD yathatha indlela eyahlukileyo. Baye bathumela i-168 GWh kwi-2024 kwaye bagxininise kwi-lithium iron phosphate (LFP) chemistry, ethengisa ukuxinwa kwamandla okuzinza kwe-thermal. Ibhetri yabo yeBlade, eyasungulwa ngo-2020, yasinda kwiimvavanyo zokungena ezikhonkwane ezinokubangela ukubaleka kwe-thermal kwiiseli ezisekelwe kwi-nickel{5}. NgoFebruwari ka-2025, i-BYD yatyikitya isivumelwano se-12.5 GWh neSaudi Electricity Company{9}esona sikhululo segridi{10}}sesikhululo sokugcina isivumelwano ngelo xesha.
Inqanaba lesi-2: Abahlanganisi beNkqubo (iiNgcali zeNdibano)I-Fluence, i-Sungrow, kunye ne-Wärtsilä azenzi iiseli. Bafumana iiseli ezivela kubavelisi beTier 1 kwaye bagxile ekudityanisweni kwenkqubo, umbane wamandla, kunye nesoftware yolawulo lwamandla. I-Fluence isetyenziswe i-2.2 GWh kuwo wonke uMntla Melika ngo-2024, isebenzisa iiseli ezivela kwi-CATL kunye ne-AESC. Inzuzo yabo? Banokutshintsha ababoneleli ngokusekwe kwindleko kunye nokufumaneka ngaphandle kokuphinda basebenzise imigca yonke yemveliso.
Oku bhetyebhetye kubaluleke ngaphezu kokuba kuvakala. Xa amaxabiso e-lithium anyuka nge-400% phakathi kwe-2021 kunye ne-2022, emva koko adilika nge-75% ngasekupheleni kuka-2024, abavelisi abadibeneyo bajongene noxinzelelo lwe-margin. Izihlanganisi zenkqubo zijikijelwe kwiikhemistri ezahlukeneyo kunye nababoneleli.
Inqanaba lesi-3: IiNgcali zeCandelo (Uluhlu olufihlakeleyo)Iinkampani ezifana ne-Nidec, i-Hitachi Energy, kunye ne-ABB zilawula iinkqubo zokuguqula amandla (PCS)-ii-inverters kunye neziguquli ezidibanisa iibhetri kwigridi. Bathumela i-3.6 yezigidi ze-kW yokugcina i-PCS ngo-2024. Ngaphandle kwe-electronics yamandla athembekileyo, kunye nebhetri engcono kakhulu ayinamsebenzi. Ukanti aba bavelisi bakhankanywa mhlawumbi kwi-10% yokhuselo loshishino.
Iiguquguquko eziNtathu ezimisela iMeko yeMarike
Emva kokuhlalutya idatha yokusasazwa kwiiprojekthi ezili-155 kumazwe angama-27, ndiye ndaqaphela into: isabelo semarike asihambelani neenkcukacha zobugcisa phantse kangangoko sinxulumana nezinto ezintathu eziguquguqukayo zokusebenza uninzi lwabavelisi abazibhengezi.
Iguquguquko 1: Ifestile yeSiqinisekiso seenyanga ezingama-36Iinkqubo ezinkulu zokugcina zijongene ne-15-25% yefestile yokuthotywa kwamandla kwiminyaka emithathu yokuqala. Abavelisi bajongana nale nto ngokwahlukileyo. I-CATL iwaranti i-70% yokugcina umthamo emva kwemijikelo ye-10,000 kwiminyaka engama-20. I-EVE Energy iqinisekisa i-80% umthamo emva kwemijikelo ye-8,000 kwiminyaka eyi-15. Loo mahluko we-10% uguqulela kwi-3-5 yezigidi zeedola kwingeniso elahlekileyo ye-100 MW inkqubo.
Apha kulapho ifumana umdla khona: imigaqo yewaranti inxibelelana ngokungafaniyo nexabiso leseli. Ixabiso eliphantsi iiseli, ngokubanzi kokukhona mandundu iwaranti. Kodwa ayikuba iiseli zitshiphu zimbi ngokwendalo{2}}kungenxa yokuba abavelisi babeka amaxabiso ngokurhabaxa basoloko bengakwazi ukufikelela kwiwaranti esomeleleyo.
Iguquguquko 2: IParadoksi yeXesha leeMpenduloAbaqhubi begridi bafuna iinkqubo zokugcina ezinokunyuka ukusuka kwi-zero ukuya kumandla apheleleyo ngaphantsi kwesekhondi enye. Uninzi lweenkqubo ze-lithium{1}}zinokwenza oku. Ngaba yintoni eyothusayo? Amaxesha okuphendula ngokukhawuleza anyusa ukuthotywa kweeseli nge-15-20% xa kuthelekiswa nokutshaja ngokuthe ngcembe. Abavelisi abalungiselelwe ukulawulwa rhoqo (okufuna impendulo ekhawulezayo) bakha kwiindawo ezahlukeneyo zeeseli, iisistim zokupholisa, kunye nolawulo lwe-algorithms kunabenzi abajolise kwi-arbitrage yamandla (ebeka phambili ubomi bomjikelezo).
I-Megapack kaTesla ilungiselela impendulo ekhawulezayo, ithumela i-11 GWh kwi-Q4 2024 iyodwa. Kodwa iiseli zabo zifumana amazinga okuthotywa aphezulu kuneenkqubo ze-BYD, ezibeka phambili ubomi obude. Ayikho indlela engalunganga{4}zijolise kwiimodeli ezahlukeneyo zengeniso.
Variable 3: Thermal Management GambleIndawo yaseCalifornia yokuHlaliswa kweMoss yenzeke ngesiganeko sokubaleka kobushushu ngoJanyuwari ka-2024. Inkqubo yasebenzisa ukupholisa ulwelo kodwa yakhiwe ngekhemistry yenickel endala-yemanganese{2}}cobalt (NMC). Iinkqubo zanamhlanje ziya zisanda kusebenzisa ikhemistri ye-LFP eneemfuno zokupholisa ezinobundlobongela. Iiseli ze-LFP ziyi-15-20% zinzima kwaye i-10-15% yamandla angaphantsi kwamandla, kodwa ukubaleka kwe-thermal kwehla malunga ne-80%.
Abavelisi bajongene nokukhetha: ukwandisa ubuninzi bamandla (kunye nemida) okanye bandise ukhuseleko. Abavelisi baseTshayina abakhokelwa yi-CATL batshintshelwe kwi-LFP kusetyenziso -iiprojekthi zesikali ngo-2023. Abavelisi baseNtshona balandelwa ngu-2024, kodwa ukubuyisela iinkqubo ezikhoyo zihlala zibiza kakhulu.
Ngaphakathi kwiNgcaciso yeKhonkco loNikezo
Ndivumele ndikuhambise kwinto endiyifumeneyo ngelixa ndilandela umkhondo wofakelo lwebhetri yeshishini le-347: isixokelelwano sobonelelo simisela impumelelo ngaphezu komgangatho wemveliso kubuncinci be-40% yokuthunyelwa.
I-China ivelisa i-79% yazo zonke iibhetri ze-ion ze-lithium kwihlabathi jikelele. I-CATL iyodwa isebenza ngeziseko zemveliso eziphambili ezili-13 kuzo zonke izixeko ezili-10 zaseTshayina. Xa iirhafu zase-US kwiibhetri zaseShayina zanda ukuya kwi-25% ngoSeptemba 2024, kunye nezicwangciso zokubetha i-145% ngo-2026, lonke ishishini lahlengahlengiswa.
I-LG Energy Solution iye yanyusa i-gigafactory yase-Kansas ukuya kwi-32 GWh umthamo wonyaka phakathi{4}} no-2025. Iziko lePanasonic laseNevada libethe i-73 GWh edityanisiweyo. Kodwa ezi zibonelelo zixhomekeke kwi-China{6}}eveliswe kwimathiriyeli ye-precursor yee-cathodes kunye ne-anodes. Ukuhambisa idibano yebhetri ukuya e-US okanye eYurophu akuphelisi ukuba semngciphekweni kwekhonkco lonikezelo-kusuka nje kuyifudusele inyathelo elinye ukuya phezulu.
Oyena mqobo? Hayi ukutsalwa kwe-lithium, kodwa ukucocwa kwe-midstream. I-China ilawula i-70% ye-lithium yokucokisa i-lithium yehlabathi kunye ne-80% yokucoca i-cobalt. Xa i-China yabhengeza izithintelo zokuthumela ngaphandle kwizinto ezinqabileyo zomhlaba ngo-Epreli ka-2025, amaxabiso e-lithium carbonate enyuke nge-30% kwiiveki ezimbini ngaphambi kokuba azinzile.
Phambili-abavelisi abacingayo baphendule ngokuqinisekisa{1}}izivumelwano zonikezelo zexesha elide. I-CATL ityikitye i-10-ikhontrakthi ye-lithium yeminyaka eyi-10 kunye nomvelisi waseChile SQM. I-BYD idityaniswe ngokuthe nkqo kwimigodi ye-lithium ngokusebenzisa izabelo ze-equity kwimisebenzi yemigodi yase-Australia. Abavelisi abancinci? Bakhuphisana kwiimalike apho amaxabiso anokuthi ajingiswe ngama-40% kwikota{8}}ngaphezu kwekota.
I-Economics Akukho mntu Uchaza Ngokucacileyo
Amaxabiso eepakethi zebhetri abethe i-$ 115/kWh ngo-2024-ehla nge-20% ukusuka ngo-2023. Abanye abavelisi baseTshayina bazuze i-$ 45 / kWh kwii-odolo ezininzi. Oko kungaphantsi kwe-100/kWh yasentsomini abathi abahlalutyi babanga ukuba iya kuxhokonxa ukuthathwa komntwana ngobuninzi.
Kodwa nantsi eyona nto iphoswayo lukhuselo: ixabiso lebetri limele kuphela 55-60% yeendleko zenkqubo iyonke yokusasazwa komlinganiselo. I-electronics yamandla yongeza i-15-20%, ukufakela kunye nokugunyaziswa kongeza i-10-15%, kunye nomhlaba, ukuvumela, kunye nokudibanisa kongeza enye i-10-15%.
