Amasistimu okugcina amandla ebhethri-esikali esikhulu agcina amandla kagesi esikalini esisetshenziswayo noma sokuhweba, ngokuvamile asuka ku-1 megawatt (MW) kuya kumakhulu ambalwa wamamegawathi omthamo. Lawa masistimu abamba ugesi uma ukukhiqizwa kweqa isidingo bese ewukhulula ngezikhathi zokusetshenziswa kakhulu noma lapho ukuphehlwa kunganele.
Ubuchwepheshe bubhekana nenselelo ebalulekile kumagridi kagesi wesimanje: ugesi kufanele usetshenziswe ngokwesiko lapho ukhiqizwa. Isitoreji sebhethri sisusa ukukhiqizwa ekusetshenzisweni, okuvumela ukuhlanganiswa okungcono kwemithombo evuselelekayo ngezikhathi ezithile njengelanga nomoya kuyilapho kugcinwa ukuqina kwegridi.
Ukuqonda I-Scale Spectrum
Isitoreji sebhethri{0}esikhulu asisona isigaba esisodwa kodwa sihlanganisa izigaba eziningi zokusebenzisa, ngasinye sisebenzisa izinjongo ezihlukile.
Igridi-amasistimu esikali(100+ i-MW) isebenza ezingeni lokudlulisela, isebenzela zonke izifunda noma izindawo ezinkulu zamadolobha amakhulu. Lokhu kufakwa kungakhipha amandla amahora angu-2 kuya kwayi-8 futhi kunikeze amasevisi egridi abalulekile njengokulawula imvamisa nokusekelwa kwamandla kagesi. Indawo yaseCalifornia Moss Landing, enamandla angu-750 MW, iyisibonelo salesi sigaba - inganika amandla cishe amakhaya angu-300,000 amahora amane.
Izinsiza-zezilinganiso zesikali(1-100 MW) ixhumeka eziteshini ezincane zokusabalalisa, isebenzela imiphakathi yasendaweni noma ezindaweni zezimboni. Uhlelo olujwayelekile lwe-20 MW olunesikhathi samahora angu-4 lugcina amandla angu-80 MWh, anele ukuhlinzeka ngezindlu ezingu-20,000 ngesikhathi sokufunwa okuphezulu kwakusihlwa. Lezi zinhlelo zivame ukubhangqwa namapulazi elanga ukuze zithwebule insalela yokukhiqiza emini.
Amasistimu-ezentengiso(100 kW kuya ku-1 MW) inikezela ngezinsiza ezinkulu njengezitshalo ezikhiqizayo, izikhungo zedatha, noma amakhempasi ezibhedlela. Nakuba emancane, aletha inani elibalulekile ngokunciphisa inkokhiso yesidingo namandla ayisipele. Uhlelo luka-500 kW lunganciphisa izindleko zikagesi zanyanga zonke zefekthri ngo-15-25% ngokushefa okuphezulu kuphela.
Umehluko ubalulekile ngoba izindleko, izinhlelo zokusebenza, nezomnotho zishintsha kakhulu ezikalini. Igridi-amasistimu esikali ngo-2024 afinyelela izindleko ezingaba ngu-$150-165/kWh afakiwe, kuyilapho amasistimu okuhweba ngokuvamile asebenzisa u-$280-400/kWh ngenxa yeminotho ephansi yesikali.
Ngaphandle kwesikali, wonke amasistimu okugcina ibhethri esikali esikhulu abelana ngesakhiwo esifanayo sobuchwepheshe esiwumongo. Amarekhi ebhethri ngokwawo athatha cishe u-40-50% wesamba sezindleko zesistimu, kodwa amanye amasistimu angaphansi amathathu anquma ukuthi ukufakwa kuyasebenza ngempela yini. Iuhlelo lokuguqula amandla (PCS)iphatha ukuguqulwa kwe-AC/DC okuphindwe kabili phakathi kwebhethri negridi. Amayunithi esimanje e-PCS afinyelela ukusebenza kahle kokuguqulwa okungu-98-99% futhi angakhuphuka asuke kuqanda aye okukhipha amandla aphelele ngaphansi kwama-millisecond angu-200. Iuhlelo lokuphatha amandla (EMS)isebenza njengobuchopho obusebenzayo, enquma ukuthi kufanele ikhokhiswe nini, ikhishwe nini, futhi ngaliphi izinga - izinqumo ezinquma ngokuqondile imali engenayo yonyaka. Izinkundla ze-EMS ezithuthukile manje zifaka-izifunzo zentengo yemakethe yesikhathi sangempela, izibikezelo zesimo sezulu, kanye nedatha yesimo segridi ukuze kuthuthukiswe ukuthunyelwa kuyo yonke imali engenayo eminingi ngesikhathi esisodwa. Isistimu yokuphatha ibhethri (BMS) iqapha{4}}izinga le-voltage yeselula, izinga lokushisa, nesimo sokushajwa ezinkulungwaneni zamaseli ngamanye, ibhalansisa ukushajwa kokusabalalisa ukuze kuvinjelwe izindawo ezishisayo kanye nokuwohloka okungalingani. Ngo ejwayelekile100 MW ukufakwa esitsheni, i-BMS iqapha amapharamitha amaseli angawodwana angaphezu kuka-200,000. Lawa masistimu amathathu - PCS, EMS, ne-BMS - kufanele axhumane ngokuqhubekayo. Ukwehluleka ekusebenzisaneni phakathi kwanoma yikuphi okubili kungadala ukuvalwa kokuvikela noma, ezimweni ezimbi kakhulu, izehlakalo zokuphepha. Kungakho izinhlelo ezinkulu zokugcina amandla ebhethri ziya ngokuya zamukela izimiso zokuxhumana ezijwayelekile njenge-Modbus TCP noma i-IEC 61850 ukuze kuqinisekiswe ukusebenzisana phakathi kwezingxenye ezivela kubakhiqizi abahlukene.
I-Large Scale Battery Energy Storage Technologies
Amabhethri e-Lithium-ion abusa-imakethe yesitoreji esikhulu, abala u-98% wokufakwa okusha ngo-2024. Ngaphakathi kwalesi sigaba, amakhemikhali amabili aqhudelana ngesabelo semakethe.
I-Lithium iron phosphate (LFP)isibe yinketho ekhethwayo yokugcina umile kusukela ngo-2022. Lawa mabhethri adela ukuminyana kwamandla athile uma kuqhathaniswa nezinye izinhlobo ze-lithium-ze-ion, kodwa anikeza izinzuzo ezibalulekile: ukuqina okushisayo okuphakeme, ukuphila komjikelezo omude (4,000-imijikelezo engu-6,000 uma kuqhathaniswa no-2,000-3,000 wezinto ezibonakalayo), aqukethe ama-chemistries aphansi noma aphansi i-nickel. Amabhethri e-LFP manje ahlanganisa cishe u-85% wokusetshenziswa kwesikali sokusetshenziswa.
I-Nickel manganese cobalt (NMC)amabhethri agcina ukuhambisana ezinhlelweni zokusebenza lapho izithiyo zesikhala zidinga ukuminyana kwamandla aphezulu. Okunye ukufakwa kwezentengiso kuzilungiselelo zasemadolobheni kukhetha i-NMC naphezu kwezindleko zeprimiyamu, ibiza ukuncishiswa kosayizi ngo-20-30%.
Amabhethri agelezayozimelela indlela ehlukile, ukugcina amandla kuma-electrolyte awuketshezi agcinwe emathangeni angaphandle. I-China ingu-100 MW / 400 MWhibhethri ye-vanadium redox flow, ekhishwe ngo-2022, ibonisa amandla obuchwepheshe obude besikhathi esingaphezu kwamahora angu-8. Amabhethri agelezayo abonisa ukuwohloka okuncane eminyakeni engu-25-30 futhi angakala umthamo wamandla ngaphandle kwesilinganiso samandla - isistimu engu-10 MWh ingagcina u-40 MWh noma u-100 MWh ngokumane ikhulise amathangi. Nokho, izindleko zabo zamanje ($300-500/kWh) nokusebenza kahle okuphansi kohambo lokuya nokubuya (65-75% uma kuqhathaniswa no-85-90% we-lithium-ion) zikhawulela ukutholwa okusabalele.
Izinhlelo zokusebenza Zesitoreji Sebhethri Isikali Esikhulu
Amasistimu okugcina amabhethri enza imali engenayo futhi anikeze inani ngamasevisi amaningi ngesikhathi esisodwa, umqondo obizwa ngokuthi "i-value stacking."
Ukulawulwa kwemvamisaigcina ifrikhwensi yegridi izinzile kokuthi 60 Hz (noma 50 Hz emazweni amaningi). Uma isidingo sikhuphuka ngokuzumayo - sithi abantu abayisigidi bavula ama-air conditioner ngesikhathi santambama esishisayo - ukwehla kwamafrikhwensi. Amabhethri angafaka amandla ngaphakathi kwama-millisecond, ngokushesha kakhulu kunokuphotha i-turbine yegesi. Ama-opharetha egridi akhokha izilinganiso ze-premium zaleli khono-lokuphendula ngokushesha. E-ERCOT (Texas), izinsizakalo zokulawula imvamisa zakha u-45% wemali engenayo yebhethri ngo-2023.
Amandla arbitrageisebenzisa umehluko wamanani usuku lonke. Amabhethri ayashaja lapho ugesi wesamba esikhulu ubiza u-$20/MWh ngo-2 AM futhi uyaphuma lapho amanani enyuka aze afike ku-$200/MWh phakathi neziqongo zakusihlwa. Nakuba ilula ngokomqondo, i-arbitrage eyimpumelelo idinga ukubikezela okuyinkimbinkimbi. Izinsuku-izintengo zemakethe ezizayo azibikezeli izimo zesikhathi sangempela-, okudala ukuchayeka engcupheni yentengo.
Ukuqinisa amandlaamandla avuselelekayo aguqula ukukhiqiza ngezikhathi ezithile kube amandla athunyelwayo. Ipulazi lelanga elibhangqwe nesitoreji sebhethri samahora angu-4 lingaqinisekisa ukulethwa kukagesi phakathi neziqongo zakusihlwa, ngisho nangemva kokushona kwelanga. Lokhu kubhanqa kubonakale kuphakeme ngokwezomnotho kunokwakha izitshalo eziphakeme kakhulu zegesi yemvelo ezimakethe eziningi. Iphrojekthi ye-Arizona Public Service yakamuva engu-850 MW yelanga + 850 yokugcina i-MWh izothatha indawo yezindawo zegesi ezigugile ezintathu ngenani eliphansi.
Ukushefa okuphezulukunciphisa izindleko ezidingekayo - inkokhiso yezinsiza ze-premium ngokudonsa kwamandla kwekhasimende okuyimizuzu eyi-15{10}}ephezulu ngenyanga. Isikhungo sokukhiqiza singase sibhekane nezindleko zokufunwa ngu-$15/kW, okusho ukuthi isipike esisodwa esingu-1 MW sibiza u-$15,000 owengeziwe nyanga zonke. Ibhethri elingu-500 kW lingashefa lezi ziqongo, lilethe izikhathi zokukhokha zeminyaka engu-3-5 ezindaweni ezibiza kakhulu.
Ikhono lokuqala elimnyamainika amandla ukubuyiselwa kwegridi ngemva kokucisha ugesi okuphelele. Isiqalo esimnyama esivamile sincike kumadamu aphehlwa ngamanzi noma kumajeneretha kadizili, kodwa amasistimu ebhethri eziteshini zokudlulisa abonise leli khono ngempumelelo e-California ngo-2021. Inzuzo yesivinini ibalulekile - ukuthi amabhethri anika amandla esiteshini ngamaminithi uma kuqhathaniswa nemizuzu engu-30-60 edingwa ngezindlela ezivamile.
Isipele sesikhungo sedatha nokuxhumanaivela njengohlelo lokusebenza lwesithupha olukhulu lwamasistimu okugcina amabhethri amakhulu. Ukwanda komthwalo wobuhlakani bokwenziwa kanye nekhompuyutha yamafu kuqhubekisele phambili ukukhula kwesidingo samandla esikhungo sedatha leyo ingqalasizinda yegridi ekhona engakwazi ukukuthwala ngaso sonke isikhathi. Ulayini wokuxhumana wemithwalo emisha yesikhungo sedatha unwebeka iminyaka engu-3-5 ezifundeni eziningi. Isitoreji sebhethri sinikeza usizo: ngokufaka-amasistimu ebhethri esikali endaweni yokuxhumana, opharetha besikhungo sedatha bangaqala ukusebenza eminyakeni ngaphambi kwalokho ukuthuthukiswa kokusetshenziswa okujwayelekile obekungasivumela, bedonsa emandleni agciniwe phakathi nezikhathi zokudingeka kakhulu kuyilapho uxhumo lwegridi lufinyelela ezidingweni zabo zokulayisha ngokugcwele. Inkampani yokutshalwa kwezimali u-Jefferies yalinganisela ngasekupheleni kuka-2025 ukuthi ama-opharetha esikhungo sedatha ye-hyperscale amele ithuba elingu-20 GW lokugcinwa kwebhethri kuze kube u-2035. Abakhiqizi bezimoto abambalwa nabo bavotele lesi sidingo - I-Ford yamemezela izinhlelo zokuguqula umthamo wokukhiqiza webhethri le-EV embonini yaseKentucky ukuze benze amasistimu okulondoloza amile aqondise isikhungo sedatha kanye nezinhlelo zokusebenza zegridi ezingaba ngu-$2 billion. Lesi sigaba sohlelo lokusebenza sasingakaze sibe khona ngaphambi kuka-2024, kodwa ngokushesha siba umshayeli obalulekile wokusetshenziswa kwesitoreji sebhethri esikhulu eduze nezinsizakalo zegridi evamile.
I-Economics and Cost Trajectory
Izindleko zokugcina ibhethri zehle kakhulu, zehle ngo-90% phakathi kuka-2010 no-2023. Le threndi iyaqhubeka, nakuba ngesivinini esinciphayo.
Ngo-2024, izindleko zesistimu ye-turnkey emaphakathi yomhlaba zifinyelele ku-$165/kWh, zehle ngo-40% ukusuka kumazinga ka-2023. Lokhu kwehliswa kudalwe ezicini ezintathu: izintengo ze-lithium carbonate ehla zisuka ku-$80,000/ton ngasekupheleni kuka-2022 zaya ku-$12,000/ton maphakathi{11}}no-2024, isikali sokukhiqiza{13}}sikhuphuka sinciphisa izindleko zephakethe lebhethri ngo-20%, kanye nokuncintisana okunamandla phakathi kwabakhiqizi baseShayina abanciphisa izindleko zesistimu{14}.
Izinguquko zesifunda zicacile. I-China izuza u-$85/kWh ngamasistimu angu-4-amahora angu-4 ekupheleni, kuyilapho amasistimu ase-US enza isilinganiso sika-$236/kWh - okuyiprimiyamu engu-177% eqhutshwa izintengo, izidingo zokuqukethwe kwasekhaya, kanye nesilinganiso semakethe esincane. Izindleko zase-Europe ziwela phakathi kuka-$180-200/kWh.
Uma sibheka phambili, insiza yokubikezela ye-NREL yango-2025{1}}yesilinganiso sezindleko zebhethri ezifinyelela ku-$147-234/kWh ngo-2035 kuye ngamanani amisha kanye nokuthuthukiswa kochungechunge lokuhlinzeka. Isimo esilandelanayo sithatha ukuthuthukiswa okuncane, kuyilapho icala elihlukumezayo lithatha amazinga okufunda aqhubekayo angu-19% wokunciphisa izindleko ngokuphinda kabili kwamandla asetshenzisiwe.
Umnotho osebenzayo unquma ukusebenza kwephrojekthi. Uhlelo lwe-100 MW / 400 MWh e-California lungase lukhiqize u-$18-25 wezigidi minyaka yonke ngokusebenzisa imali engenayo ehlanganisiwe: $8-12M kusuka ku-arbitrage yamandla, $6-8M ekukhokheleni umthamo, kanye no-$4-5M kusuka kumasevisi asekelayo. Ngokuphikisana nezindleko zekhephithali eyizigidi ezingama- $66, lokhu kuletha imbuyiselo yeminyaka emi-3-4 ngaphambi kwezindleko zezimali.
Nokho, ukugcwala kwezimakethe kuletha izinselelo ezivelayo. Ku-ERCOT, ukusetshenziswa okusheshayo kwebhethri kucindezela amathuba e-arbitrage - ukuphakama okumaphakathi-ukuze{3}}kwehliswe-ukusabalala kwentengo ephakeme kakhulu kunciphe ukusuka ku-$85/MWh ngo-2022 ukuya ku-$52/MWh ngo-2024 njengoba amabhethri ashelela ijika lentengo. Onjiniyela manje kufanele balungiselele ukuthunyelwa ngokucophelela okukhulu futhi bathembele kakhulu emalini engenayo yemakethe yamandla.
Ukukhula Kwemakethe Kwamanje
Imboni yokugcina amabhethri ibhekene nokwanda okuqhumayo. Ukuthunyelwa komhlaba wonke kufinyelele ku-69 GW / 169 GWh ngo-2024, okumelela u-55% wonyaka-phakathi-nokukhula konyaka. Isitoreji se-Lithium{8}}se-ion kulindeleke ukuthi sidlule isitoreji sikagesi ompontshwa ngamanzi ngamanani aphelele wamandla phakathi no-2025, nakuba i-hydro pumped igcina izinzuzo zengqikithi yokugcinwa kwamandla ngenxa yomthamo wayo wesikhathi eside.
I-United States ihamba phambili ngesivinini sokuthunyelwa. Umthamo webhethri ukhule usuka ku-1 GW ngo-2020 waya ku-17 GW ngo-2024, kanti omunye u-15 GW uhlelelwe u-2024 kanye no-9 GW ngo-2025. I-California ne-Texas iyabusa, ndawonye ibala u-65% wamandla ase-US. I-California ihamba phambili nge-7.3 GW efakiwe, eqhutshwa amandla anamandla avuselelekayo kanye nesidingo sokushintsha izitshalo zegesi esezithathe umhlalaphansi. I-Texas ilandela ngo-3.2 GW, lapho umnotho webhethri uvuna kakhulu ngenxa yamandla e-ERCOT-kuphela idizayini yemakethe kanye nokushintshashintsha kwentengo okwedlulele.
Ngale kwalezi zifunda ezihamba phambili,-isitoreji esikhulu sebhethri siyahlukahluka ngokwendawo. Ngo-2025, insiza entsha{3}}ukufakwa kwesikali kwavela ezifundazweni ezingu-13 ezihlukene, kwephula i-California-i-Texas duopoly eyayibonakala eminyakeni edlule. ENyakatho-mpumalanga ye-Ohio, ubambiswano oluholwa yi-Cuyahoga County luthatha indawo yejeneretha-yangaphambili evuthayo yamalahle ngo-10-20 MW wesitoreji sebhethri kanye no-63 MW welanga kuwo wonke amasayithi ase-brownfield, axhaswe umklomelo we-EPA wezigidi ezingu-129.4. I-Tallahassee Electric and Gas Utility yaseFlorida ithole uxhaso lwe-$28.7 million ye-DOE yesistimu yebhethri engu-10-25 MW e-Birmingham Street Substation, eklanyelwe ngokukhethekile ukunikeza amandla ayisipele ezindaweni ezinganakekelwa kahle ngokomlando phakathi nezimo zezulu ezimbi kakhulu. E-New Brunswick, eCanada, i-Saint John Energy ibambisene ne-Natural Forces ukuze ifake amabhethri e-Tesla Megapack eduze ne-Burchill Wind Farm, okwenza ukufakwa kwebhethri enkulu kunazo zonke esifundazweni. Lawa maphrojekthi abonisa indlela amasistimu amakhulu okugcina amabhethri ahamba ngayo ngale komnotho omsulwa ukuya ekuqiniseni umphakathi, ukulungiswa kwemvelo, nokulingana kwamandla - izinhlelo zokusebenza ezinweba imakethe ekwazi ukubhekana nezimo ezingaphezu kwezinsiza zegridi evamile.
I-China isalokhu iyimakethe enkulu kunazo zonke emhlabeni jikelele, ifaka cishe u-35 GW 2024 - cishe uhhafu wezengezo zomhlaba wonke. Iziyalezo zikahulumeni ezidinga amaphrojekthi avuselelekayo ukuthi afake isitoreji (imvamisa u-10-20% womthamo wokuphehla nobude besikhathi samahora angu-2) uqhubekisela phambili okuningi kwalokhu kukhula. Umthamo omkhulu wezwe wokukhiqiza amabhethri kanye namaketanga okunikezwa kwempahla yasekhaya kwenza izindleko zibe ngaphansi kwama-30-50% ngaphansi kwamazinga omhlaba.
Ubude bephrojekthi buyanda njengoba umnotho uthuthuka isikhathi eside-sesitoreji. Isilinganiso sobude bebhethri sikhuphuke sisuka emahoreni angu-1.8 ngo-2020 saya emahoreni angu-2.4 ngo-2024, ngamasistimu angu-4-amahora angu-4 abe ajwayelekile ekufakweni kwesilinganiso sokusetshenziswa okusha. Amaphrojekthi amaningana angamahora angu-6-8 afinyelelwe ekusebenzeni ngo-2024, nakuba izindleko ezingaphezu kwamahora ama-4 zihlala ziphezulu ngo-15-25% nge-kWh ngayinye yomthamo.
Lokhu kunwetshwa okusheshayo kokusetshenziswa{0}}kokusetshenziswa kwesikali sesitoreji sebhethri kubumba kabusha izimakethe zempahla yomhlaba wonke ngezindlela ezinwebeka kakhulu ngale komkhakha wamandla. Ngokusho kwe-IEA's 2025 Global Critical Minerals Outlook, isidingo se-lithium senyuke cishe ngama-30% ngo-2024, sedlula kakhulu izinga lokukhula lonyaka elingu-10% elibonwa phakathi nawo wonke ama-2010. Ukugcinwa kwebhethri nezimoto zikagesi zihlangene kubalele u-85% wengqikithi yokukhula kwesidingo se-lithium, i-nickel, i-cobalt, ne-graphite eminyakeni emibili edlule. Imithelela ye-supply chain iyahluka ngezinto. I-Lithium ibhekene nokushoda kokuhlinzeka ngo-40% ngo-2035 ngaphansi kwezilungiselelo zenqubomgomo zamanje, ngisho nokubalwa kwezimali kumaphrojekthi ezimayini amenyezelwe. Isidingo se-nickel sikhula ngokulingene kakhulu ngo-6-8% ngonyaka, kodwa ukugxiliswa kwendawo kuyakhula - amazwe amathathu aphezulu akhiqizayo kulindeleke ukuthi alawule ukunikezwa kuka-85% ngo-2035, kusuka ku-75% ngo-2024. I-Copper inikeza mhlawumbe umbono oyinselele kakhulu. Ukunwetshwa kwengqalasizinda yegridi, ikakhulukazi e-China, kube yikona okubambe iqhaza elikhulu kakhulu ekukhuleni kwesidingo sekhopha muva nje, futhi konke ukufakwa kwebhethri enkulukazi kudinga ithusi eliningi lamabhasi, izintambo, ama-transformer kanye nengqalasizinda yokuxhuma igridi. I-IEA ihlela ukushoda kokuhlinzekwa kwekhopha okungama-30% ngo-2035 ngokusekelwe kumaphrojekthi amenyezelwe njengamanje.
Ukubusa kwekhemistri ye-LFP{0}}esikalini esikhulu sokulondoloza amandla ebhethri kunciphisa kancane ukukhathazeka kokunikezwa. Ngenxa yokuthi ama-cathode e-LFP asebenzisa i-ayoni ne-phosphate esikhundleni se-nickel ne-cobalt, ukusuka ku-NMC ukuya ku-LFP kwehle -ngekilowatt-ngehora isidingo salezi zinsimbi ezibiza kakhulu. Kodwa-ke, amabhethri e-LFP asadinga i-lithium nethusi ngamanani aqhathaniswayo. Njengoba ukusetshenziswa kwaminyaka yonke kuqhubeka kukhuphukela ku-100+ GW emhlabeni jikelele, isamba esiphelele sezinto zokusetshenziswa ezisetshenziswa amasistimu okugcina amabhethri amakhulu azoqhudelana ngokwandayo nokukhiqizwa kwezimoto zikagesi ukuze kutholakale - ukushuba kwesimo esingaba nomthelela ekukhethweni kwekhemistri yebhethri nezintengo kuyo yonke le minyaka eyishumi.
Izinselele zobuchwepheshe Kusitoreji Samandla Ebhethri Isikali Esikhulu
Naphezu kwentuthuko esheshayo, izithiyo ezinkulu zobuchwepheshe ziyaqhubeka.
Ukuphepha komliloisala iwukukhathazeka okuphambili ngemuva-kwezehlakalo eziphezulu ezikhungweni ezihlanganisa i-Moss Landing e-California. Amasistimu wesimanje ahlanganisa izendlalelo eziningi zokuphepha: amasistimu okuphatha okushisayo agcina izinga lokushisa elilungile lokusebenza (ngokuvamile i-15-35 degree), izinzwa zokuxwayisa kusenesikhathi zibona ukuziphatha okungavamile kwamangqamuzana, futhi izinhlelo zokunciphisa umlilo zisebenza ngokushesha uma ukugijima okushisayo kuqala. Ukufakwa kufanele kuhambisaneAmazinga e-NFPA 855 okugcinwa kwamandla ebhethri okufakwe esitsheni, ecacisa isikhala phakathi kwamarack ebhethri, izidingo zokungenisa umoya, nokucaciswa kwesistimu yokucindezela. Izinga lesigameko lithuthuke kakhulu - izehlakalo ezinhlanu zokuphepha ezibalulekile kuphela ezenzeke emhlabeni wonke ngo-2024, zehle zisuka kweziyi-11 ngo-2022.
Ukuphepha{0}}kweleveli yeseli kuthuthukile ngokusebenzisa okuthuthukisiwe kwesihlukanisi kanye nokwakheka kwe-electrolyte ukumelana nokusakazeka kokubaleka kwe-thermal. Ukuzinza kwe-LFP chemistry kwe-thermal kunomthelela emakethe yayo - Amaseli e-LFP amelana nokushisa okushisayo kuze kube ngu-270 degree, uma kuqhathaniswa no-150-180℃kumaseli e-NMC.
Ukuphathwa kokwehliswa kwesithunzikuthinta ngqo ezomnotho zamaphrojekthi. Umthamo webhethri uyanyamalala ngomjikelezo ngamunye wokushajwa{1}}nangokuguga kwekhalenda. Ibhethri eligunyazwe imijikelezo engu-4,000 ekujuleni okungama-80%-kokuthi{7}}ukukhipha{7}}lingase ligcine u-80% womthamo wangempela ngemva kweminyaka engu-10 uma lihamba ngamabhayisikili nsuku zonke, kodwa ukuwohloka kuyashesha ngamazinga okushisa aphezulu, ukuchithwa okujulile, noma amazinga okushaja okusheshayo.
Amasistimu okuphatha amabhethri asezingeni eliphezulu (BMS) abhalansisa izinjongo eziqhudelanayo: ukukhulisa imali engenayo eseduze-yesikhathi eside kuyilapho kugcinwa{1}}umthamo wesikhathi eside. Ukusebenza ngaphakathi kwebanga lamandla kagesi elincane (ake uthi, 20-90% isimo sokushaja kuno-10-95%) kunweba ubude bempilo ngezindleko zomthamo otholakalayo. Ama-algorithms okuthumela asuselwa ku-AI akhulisa kakhulu lokhu kuhwebelana, eveza imali engenayo phakathi nesikhathi sokuphila kwephrojekthi kunokukhulisa inzuzo yanamuhla.
Ingqalasizinda yokugaya kabushaisalokhu ingathuthukisiwe ngokuqhathaniswa namazinga okuthunyelwa. Amabhethri e-Lithium-ion afinyelela esiphethweni-se{3}}empilo aqukethe izinto ezibalulekile - iphrojekthi engu-1 GWh iphethe cishe amathani angu-200 e-lithium namathani angu-100 e-nickel - kodwa izinqubo zamanje zokugaywa kabusha zithola kuphela u-50{11}}70% walezi zinto ngokwezomnotho. Izinhlelo zokusebenza "-zesibili}zezempilo", lapho amabhethri e-EV ehliswe izinga aze afike kumthamo ongu-70-80% anikeza isitoreji esimile, angase andise ukuphila okusebenzisekayo ngeminyaka emi-5-10. Ukuthunyelwa kwakamuva kwe-Redwood Materials kokufakwa kwebhethri okukhulu kakhulu kwempilo yesibili emhlabeni (kusetshenziswa amaphakethe e-EV athathe umhlalaphansi) kubonisa le ndlela, nakuba imibuzo emayelana nokuthembeka newaranti iqhubeka.
Ubunkimbinkimbi bokuhlanganiswa kwegridi increases as battery penetration grows. Batteries behave fundamentally differently from synchronous generators - they lack rotational inertia that traditionally helps stabilize grid frequency. At high battery penetration (>30% womthamo), abaqhubi begridi kumele basebenzise amasu amasha okulawula. Okuhlangenwe nakho kwe-Australia 3+ kwe-GW yamabhethri axhunywe kugridi encane (30 GW peak demand) kunikeza izifundo ezibalulekile: izilawuli eziyinkimbinkimbi zokuguqula izinto zingalingisa inertia ngokusebenzisa amandla "e-synthetic inertia" noma "impendulo yemvamisa esheshayo", kodwa lezi zici zidinga ukucushwa ngokucophelela.
Intuthuko Esafufusa
Amathrendi amaningana abumba kabusha indawo yesitoreji.
Amanye amakhemistribathuthukela kwezentengiselwano. Amabhethri e-sodium-ion, athatha indawo ye-sodium eshibhile, echichimayo esikhundleni se-lithium, afinyelele ukukhiqizwa okukhulu ngo-2023. Amaseli e-CATL -esizukulwane sokuqala se-sodium{4}}afinyelela ubukhulu bamandla obungu-160 Wh/kg - cishe obungu-30% obuphansi kune-LFP kodwa anele ukusetshenziswa okumile. Uma izikali zokukhiqiza, i-sodium-ioni ingase yehlise izindleko ze-LFP ngo-20-30% kuyilapho isusa ukukhathazeka mayelana nezingqinamba zokunikezwa kwe-lithium.
Amabhethri e-ayoni-omoya athembisa-ubude bezinsuku{1}eziningi ngesikhathi sezindleko ezingashintsha ngokuyisisekelo indlela amagridi aphatha ngayo izikhathi ezinwetshiwe{2}}ezivuselelekayo. Ubuchwepheshe be-Form Energy bugcina amandla ngokugqwala kwe-iron okubuyisela emuva - ngesikhathi sokuphuma, insimbi eyinsimbi iphendulana nomoya-mpilo ovela emoyeni yenze i-iron hydroxide (ukugqwala), ikhiphe ama-electron; ngesikhathi sokushaja, ugesi uhlehlisa ukusabela futhi ubuyisela insimbi esimweni sayo sensimbi. Inqubo isebenzisa i-ayoni, enye yezinsimbi ezichichima kakhulu nezishibhe kakhulu Emhlabeni, futhi i-Form Energy iqondise izindleko zamandla ezentengiselwano ezingu-$20/kWh esikalini - esicishe sibe ingxenye eyodwa{8}}yeshumi yesistimu-yezindleko zeleveli ye-lithium{10}ion enkulu{11}}yesikali sezinhlelo zokugcina amandla ebhethri.
Umugqa wesikhathi wokuthengisa we-Form Energy manje usubonakala ungokoqobo. Iphrojekthi yokuqala yenkampani yokuhlola, isistimu engu-1.5 MW / 150 MWh eyakhiwe nge-Great River Energy yaseMinnesota, yaqala ukusebenza ngasekupheleni kuka-2025 futhi ihlolwa{4}}iminyaka eminingi. Ukuthunyelwa okukhudlwana okuningana kuyaqhubeka: amaphrojekthi amabili angu-10 MW we-Xcel Energy, ukufakwa okungu-5 MW / 500 MWh okusekelwa yisibonelelo seKhomishini Yamandla Yamandla yaseCalifornia engu-$30 million endaweni ye-PG&E e-Mendocino County, kanye nephrojekthi yokubonisa engu-10 MW / 1 GWh eNew York esekelwe uxhaso lwe-NYSERDA. Iphrojekthi ebaluleke kakhulu yenkampani - ukufakwa okungu-85 MW / 8,500 MWh endaweni yokugaya eguquliwe e-Lincoln, e-Maine - izoba iphrojekthi yebhethri enkulu kakhulu ngomthamo wokugcina amandla emhlabeni uma iqedwa njengoba kuhleliwe, kanti ukwakhiwa okulindeleke kuqale ngo-2027.
Ngasohlangothini lokukhiqiza, i-Form Energy yathola u-$405 wezigidi ngoxhaso lwe-Series F ngo-2024 futhi yakha indawo yayo yokukhiqiza - I-Form Factory 1 - e-Weirton, e-West Virginia, endaweni yomshini wangaphambili wokugaya insimbi. Ukunwetshwa kwamamitha-skwele angu-300,000 kakade kuyakhiwa, okuqondiswe kumpambuko wokukhiqiza ngo-2026. Le nkampani iphinde yasayina imemorandamu yokusebenzisana ne-GE Vernova ukuze isekele ukuhlanganiswa kwesistimu futhi yamemezela umzila wepayipi wephrojekthi engu-85 GWh ngo-2028. Amabhethri e-iron{10}}anokuzungeza okuphansi{11}}i-lithionlyumly{0} {0}uhambo lwe-lithion%2} {0} 6 uma kuqhathaniswa nama-90%), futhi ukuminyana kwawo kwamandla kuphansi kakhulu, okuwenza abe mkhulu. Kodwa ngezinhlelo zokusebenza ezinkulu-zesitoreji samandla lapho ubude behora{18}}buyi-100 bubaluleke ngaphezu kophawu lwezinyawo - esikhundleni sezitshalo eziphakeme kakhulu zegesi phakathi{20}}nezehlakalo zesimo sezulu sezinsuku eziningi, isibonelo - lokhu kuhwebelana kungase kwamukeleke. Isistimu ye-Form Energy's iron's iron{24}}iphinde yaphumelela ukuhlolwa kokuphepha kwe-UL 9540A ngaphandle kwelangabi noma ukushisa okushisayo, okuzuzisa kakhulu kune-lithium{25}}i-ion endaweni engezwani nomlilo.
Ukulungiselelwa kwe-AIiba yindinganiso. Ama-algorithms okufunda komshini ahlaziya amashumi eminyaka edatha yenani lemakethe, izibikezelo zesimo sezulu, nezimo zegridi ukuze zibikezele amaphethini enkokhiso alungile{1}}. Lezi zinhlelo zingathuthukisa imali engenayo ngo-8-15% uma kuqhathaniswa namasu alula we-arbitrage. I-AI yokulungiswa okuqagelayo iqapha izinkulungwane zamapharamitha weleveli yeseli, ihlonza amaphethini okonakaliswa abonisa ukwehluleka okuzayo emavikini ambalwa ngaphambi kokuba kwenzeke.
Izitshalo zamandla abonakalayo (VPPs)hlanganisa amabhethri asabalalisiwe abe yizindiza ezihlanganisiwe. I-VPP ingase ihlanganise amabhethri okuhlala angu-10,000 kanye nezinhlelo zezentengiselwano ezingu-50, afinyelela ku-200 MW wamandla alawulekayo. Ama-opharetha egridi angathumela le mikhumbi ebonakalayo njengesikhungo samandla esivamile. Izinhlelo ze-VPP zase-Hawaii zibonise ukuthi amabhethri ezindawo zokuhlala, ahlanganiswe kahle, ahlinzeka ngezinsizakalo zokulawula imvamisa efanayo nokusetshenziswa{7}}kokufakwa kwesikali.
Umugqa ophakathi kwesitoreji sebhethri lendawo kanye-nokugcinwa kwamandla esikalini uya ufiphala ngokwandayo, futhi umfutho osheshayo wokwamukelwa kwesitoreji sebhethri wengeza insiza ebalulekile esabalalisiwe kugridi. Imakethe yendawo yokuhlala yase-US ifinyelele irekhodi elingu-2.7 GW efakwe 2025 - ekukhuphukeni okungu-92% ukusuka 2024 - okuqhutshwa ngokwengxenye abanikazi bezindlu abajaha ukuthwebula amakhredithi entela yombuso aphelelwa yisikhathi. Emhlabeni jikelele, amakhaya angaphezu kwezigidi ezingu-12 manje anezinhlelo zokugcina amabhethri, amazinga okungena edlula ama-20% eJalimane, e-Australia nase-Japan. Ngaphezu kwama-50% wokufakwa okusha kwe-solar e-Europe manje sekuhlanganiswe nesitoreji.
Lokhu kukhula kwendawo yokuhlala kubalulekile-emakethe enkulu yokugcina amabhethri ngezindlela ezimbili. Okokuqala, ishayela isikali sokukhiqiza. Amaseli e-LFP afanayo akhiqizwa kuma-gigafactory ahlinzeka kokubili ngamayunithi okuhlala kanye{3}}neziqukathi zesikali esiwusizo. Amavolumu okukhiqiza ahlanganisiwe aphezulu acindezela izindleko zamaseli zehle kuwo wonke umuntu. Okwesibili, amabhethri okuhlala ahlanganisiwe aba insiza yegridi ngokwawo. E-Texas, i-Base Power ikhiqiza, ifake, ibe ngumnikazi, futhi isebenzise amabhethri okuhlala anikeza amandla ayisipele kubanikazi bezindlu ngenkathi kanye kanye iletha izinsiza zegridi. E-Massachusetts, Arizona, nase-Illinois, izinhlelo ezinwebayo zesikhungo samandla abonakalayo kushintsha izinkulungwane zamabhethri asekhaya abe yizindiza ezihlanganisiwe ezisebenza njengesistimu-yesikali yokugcina amandla ebhethri. Lezi zinhlelo zibonisa ukuthi ukwamukelwa kwesitoreji sebhethri yendawo yokuhlala akuyona imakethe ehlukile kunesisetshenziswa{10}}sesikali sesitoreji - amasegimenti amabili ahlangana ezinhlosweni ezifanayo zokuthembeka kwegridi, amakhemistri webhethri afanayo, kanye nezinkundla ezifanayo zokuthumela.
Inqubomgomo kanye Nendawo Yokulawula
Izinqubomgomo zikahulumeni ziya ngokuya zibona isitoreji njengengqalasizinda ebalulekile.
I-US Inflation Reduction Act (IRA) inikeza ikhredithi yentela yokutshala engu-30% yesitoreji sebhethri esizimele, ngaphambilini esasitholakala kuphela kumasistimu abhangqwe nelanga. Lolu shintsho lwenqubomgomo lucuphe igagasi lesitoreji-amaphrojekthi kuphela - 40% ka-2024 ukusetshenziswa kwase-US bekungamasistimu azimele uma kuqhathaniswa no-15% ngo-2022.
Nokho, ukungaqiniseki kwentela kufiphaza umbono wemakethe yase-US. Ukunyuswa kwentengo okuhlongozwayo kweSigaba 301 kungase kukhuphule izindleko ngo-50-60% kumasistimu asebenzisa izingxenye zebhethri zase-China. Uma amanani angu-60% kumarekhi ebhethri aseShayina eqala ukusebenza ngo-2026, i-NREL ilinganisela ukuthi izindleko zase-US zizobuyela kumazinga angu-2024 ($236/kWh), okungenzeka kubambezele umfutho wokuphakelwa.
Iziyalezo zephothifoliyo evuselelekayo yaseShayina ziphoqa amaphrojekthi amasha elanga nomoya ukuthi afake isitoreji esimelela u-10-20% womthamo wokukhiqiza osebenza amahora angu-2-4. Le nqubomgomo iqinisekise u-15-20 GW wesidingo sesitoreji saminyaka yonke, esiqhuba ukutshalwa kwezimali kokukhiqizwa kwasekhaya kanye nokusheshisa ukuncipha kwezindleko okuzuzisa izimakethe zomhlaba.
Amakhodi egridi ye-European Union aya ngokuya edinga amabhethri ukuze anikeze amandla "egridi-okwenza", okuwenza akwazi ukusungula amandla kagesi azinzile kanye nemvamisa kunokumane alandele izimo zegridi. Lezi zidingo ezithuthukisiwe zengeza u-5-10% ezindlekweni zesistimu kodwa zithuthukisa ukuqina kwegridi njengoba ukungena kwebhethri kukhula.
Ukuqhathanisa Nezinye izindlela
Isitoreji sebhethri siyaqhudelana futhi sihambisana nobunye ubuchwepheshe bokulondoloza.
Isitoreji samanzi esimpompaisabusa umthamo womhlaba wonke ku-181 GW, okwenza kube kuncane okungu-88 GW wesitoreji sebhethri kusukela ngo-2024. I-Pumped hydro inikezela ngo-8-ubude besikhathi samahora angu-20 kanye nokusebenza kahle okungu-80-85% kokuya nokubuya ngezindleko zika-$2,000-4,000/kW. Kodwa-ke, izidingo zesiza ziyakhawula - amaphrojekthi adinga amadamu afanelekile aphezulu naphansi anomehluko wokuphakama wamamitha angama-200-500. Izikhathi zokuvumela zithatha iminyaka engu-5-15. Ayikho i-hydro pumped hydro entsha eza ku-inthanethi e-United States phakathi kuka-2010 no-2024, nakuba amaphrojekthi ambalwa asezigabeni zokuhlela ezithuthukisiwe angase aqede lesi somiso.
Amabhethri ahamba phambili lapho i-hydro pumped ihluleka khona: indawo eguquguqukayo, ukusetshenziswa okusheshayo (izinyanga ezingu-12-ezingu-18 uma kuqhathaniswa neminyaka engu-7-15), kanye nezomnotho eziphakeme zesikhathi esifushane. Kuzinhlelo zokusebenza ezingaphansi kwamahora angu-8, amabhethri ngokuvamile anikeza izindleko eziphansi kanye nezikhathi zokuphendula ngokushesha.
Isitoreji samandla omoya acindezelwe (CAES)isebenzisa ugesi owedlulele ukuze icindezele umoya emihumeni engaphansi komhlaba, kamuva iwunwebe ngama-turbines ukuze ikhiqize amandla. Zimbili kuphela izitshalo ze-CAES ezisebenza emhlabeni wonke (eyodwa e-Alabama, eyodwa eJalimane). Ubuchwepheshe budinga igeology efanele - imigede kasawoti noma izinkundla zegesi eziphelile - okukhawulela amandla okusetshenziswa.
Isitoreji se-hydrogeninikeza amandla esikhathi sesizini - okugcina amandla amaviki noma izinyanga kunamahora. Ama-electrolyzer aguqula ugesi ube yi-hydrogen, engagcinwa emathangeni noma emigedeni engaphansi komhlaba bese kamuva ishiswa kuma-turbine noma kuma-fuel cell. -ukusebenza kahle kohambo lokuya nokubuya akulungile (35-}50%) futhi izindleko zihlala ziphezulu ($400-800/kWh), kodwa ngokulinganisa ukuhlukahluka kwesizini ekukhiqizeni okuvuselelekayo, i-hydrogen ingase ibonakale ibalulekile. Amaphrojekthi amaningana okulinga ahlola ama-hybrids ebhethri le-hydrogen aqalwa ngo-2024.
imibuzo ejwayelekile ukubuzwa
Ihlala isikhathi esingakanani-isistimu yesitoreji sebhethri enkulu?
Amasistimu e-lithium-yesimanjemanje aqinisekisa iminyaka engu-10-iminyaka engu-15 noma engu-4,000-imijikelezo yokushaja engu-6,000 egcwele{8}}yokukhipha, kuye ngokuthi ikuphi okuza kuqala. Isikhathi sokuphila sangempela{15}somhlaba sincike kakhulu ezimeni zokusebenza - ukujula kokukhishwa, ukuphathwa kwezinga lokushisa, nokuvama kokuhamba ngamabhayisikili konke kuthinta izilinganiso zokuwohloka. Amabhethri e-LFP ngokuvamile adlula okuhlukile kwe-NMC ngo-30-50% ngenxa yokuzinza komjikelezo ongcono. Abanye abakhiqizi manje banikeza iziqinisekiso zeminyaka engu-20 zezinhlelo ze-LFP ezinemikhawulo ethile yokusebenza. Ngemuva kwempilo yokuqala yesevisi, umthamo uvamise ukwehlela ku-70-80% woqobo lwangempela, lapho amabhethri angase aphinde asetshenziswe ukuze kusetshenziswe izinhlelo zokusebenza zempilo yesibili ezingadingeki kangako ngaphambi kokuvuselelwa kabusha.
Kwenzekani kulawa mabhethri ekupheleni kwempilo?
Izinqubo zamanje zokugaywa kabusha zithola u-50-95% wezinto ezisetshenziswayo kuye ngekhemistri kanye nendlela yokugaywa kabusha. Izindlela ze-Pyrometallurgical (smelting) zibuyisela i-cobalt, i-nickel, nethusi kodwa zilahlekelwa i-lithium. Izinqubo ze-Hydrometallurgical (amakhemikhali) zingabuyisa zonke izinto ezibalulekile ngokusebenza kahle okungama-85-95% kodwa zibiza ngaphezulu. Izindlela zokugaywa kabusha eziqondile ezigcina ukwakheka kwe-cathode ziyavela kodwa azikakathengi esikalini. Izidingo zokulawula ziya ngokuya zigunyaza ukugaywa kabusha - Imithetho yebhethri ye-EU idinga u-95% wezilinganiso zokuqoqwa kanye namaphesenti amancane okubuyisela wezinto ezibalulekile ngo-2030. Uma kubhekwa izilinganiso zamanje zokuphakelwa, amavolumu ebhethri okuphela kwempilo azokhuphuka ngemuva kuka-2030, okudinga ukunwetshwa okukhulu kwamandla okusebenzisa kabusha.
Amabhethri aqhathaniswa kanjani nezitshalo eziphakeme kakhulu zegesi?
Amabhethri aya ngokuya edlula izitshalo eziphakeme kakhulu zegesi ngokonga isikhathi esingaphansi kwamahora angu-4-6. Isistimu yesitoreji sebhethri engu-100 MW ingase ibize u-$40-izigidi ezingu-50 uma iqhathaniswa nezigidi ezingu-$80-ezingu-100 wezigidi ngenani elilinganayo legesi eliphakeme. Izindleko zokusebenza zivuna amabhethri ngendlela ecace nakakhulu - azikho izindleko zikaphethiloli, ukunakekelwa okuncane, kanye nezikhathi zokuphendula ezisheshayo ezithwebula izimakethe zesevisi ezihambisana nenani eliphezulu. Amabhethri angakhuphuka asuke kuziro aye ekuphumeni okugcwele ngama-milliseconds uma kuqhathaniswa nemizuzu eyi-10-30 kumaturbine egesi. Kodwa-ke, izitshalo zegesi zingasebenza unomphela ngenkathi zifaka uphethiloli (zinqunyelwe kuphela ukunikezwa kukaphethiloli), kuyilapho amabhethri ecindezelwe amandla. Ngokucisha okunwetshiwe noma imicimbi ephakeme kakhulu yezinsuku eziningi, ukukhiqizwa kwegesi kugcina izinzuzo.
Yini evimbela ukuthunyelwa kwesitoreji sebhethri esisheshayo?
Ukubambezeleka koxhumano lwegridi kumelela ibhodlela eliyinhloko. Ezifundeni eziningi, amaphrojekthi esitoreji alinda iminyaka engu-3-7 emigqeni yokuxhumana njengoba ama-opharetha egridi efunda imithelela futhi ahlonze ukuthuthukiswa kokudlulisela okudingekayo. Amaphesenti angu-28 kuphela amaphrojekthi akulayini wokuxhumana we-ISO wase-US afinyelela ngokomlando ekusebenzeni kwezentengiso. Imikhawulo yochungechunge lokuhlinzekwa kwamaminerali abalulekile (i-lithium, i-cobalt, i-nickel) iyaqina ngezikhathi ezithile, nakuba ukuphahlazeka kwentengo ka-2024 okubonisa ukutholakala ngokweqile kungase kwenzeke. Izinselelo zezimvume ziyahlukahluka ngendawo - eminye imiphakathi imelana nensizakalo{12}}ukufakwa kwesikali ngenxa yokukhathazeka kokuphepha emlilweni noma imithelela yobuhle. Izinhlaka zezezimali kanye nesiqiniseko semali engenayo nakho kubalulekile; amaphrojekthi ngokuvamile athwala kanzima ukuze athole uxhaso olukahle ngaphandle kwezinkontileka zesikhathi eside eziqinisekisa ubuncane bemali engenayo.
Isitoreji{0}esikhulu sebhethri sishintshile sisuka kubuchwepheshe be-niche saya kusisetshenziswa segridi eyisisekelo esikhathini esingaphansi kweminyaka eyishumi. I-trajectory yezindleko iyaqhubeka yehla, nakuba amanani okunciphisa ngo-19% ngonyaka weshumi leminyaka elidlule angase ehle njengoba ubuchwepheshe bukhula. Idizayini yemakethe kanye nezinhlaka zokulawula ziyazivumelanisa nezimo ukuze kuhlangatshezwane nalesi sigaba sempahla. Njengoba ukusetshenziswa kwamandla avuselelekayo kushesha emhlabeni wonke, isitoreji samandla ebhethri esikhulu sizobaluleka njengengqalasizinda yokudlulisela - ukuguquka kusuka kubuchwepheshe obusha kuya kumishini yegridi evamile evumela ugesi othembekile, othengekayo.
Okuthathwayo Okubalulekile
Isitoreji -esikhulu sivala ukufakwa okungu-1 MW ukuya 750+ kwe-MW okuhlinzeka ngezinsizakusebenza nezokuthengisa
Izindleko zehle ngo-90% ngo-2010-2023 futhi ziyaqhubeka nokwehla, zafinyelela ku-$85-236/kWh ngo-2024 kuye ngendawo.
I-Lithium iron phosphate (LFP) ibusa isitoreji esimile ngesabelo semakethe esingu-85% ngenxa yokuphepha, ukuphila isikhathi eside, kanye nezinzuzo zezindleko.
