Igridi yombane ayizange yenzelwe ukugcina amandla. Ngaphezu kwenkulungwane, oomatshini bombane bevelisa umbane kwaye bawutyhalela ngoko nangoko ngeentambo zothumelo eziya emakhaya nakumashishini. Yigcine? Oko kwakungeyonxalenye yesicwangciso.
Emva koko iiphaneli zesola kunye neeinjini zomoya zafika nengxaki: zivelisa amandla xa indalo igqiba, hayi xa abantu bewadinga. Oku kungafani kwadala i-174 yeebhiliyoni zeerandi ishishini ngokwesiqhelo-ugcino lwegrid yesikali sebhetri{3}}nto leyo etshintsha kakhulu indlela osebenza ngayo umbane.
Kodwa nantsi into ephoswa ziingcaciso ezininzi: iibhetri zegridi aziyiyo nje iinguqulelo ezinkulu zento ekwifowuni yakho. Ziinkqubo ezicwangcisiweyo apho ikhemistri, isoftware, kunye nezoqoqosho zidibana ngeendlela ezibonisa ukuba urhulumente wakho unokuqhuba ngamandla acocekileyo okanye into eluncedo yenza imali ngokugcina amandla omoya nge-2am.
Le yindlela esebenza ngayo yonke inkqubo-ukusuka kwi-lithium ion ukushixiza phakathi kwe-electrode ukuya kumandla ebhidi ye-algorithms kwiimakethi zemilliseconds phambi kwebango spikes.
Ezintathu-Inyani Zomaleko: Ngokwenene UGcino Lwegridi Lusebenza Njani
Amanqaku amaninzi aphatha iibhetri zegridi njengeebhokisi ezimnyama "ezihlawulisa kwaye zikhuphe." Oku kufana nokuthi inqwelomoya "yinyuka kwaye yehla." Yinyani, kodwa ayinamsebenzi ukuba ufuna ukuqonda okwenzekayo.
Ukugcinwa kwebhetri yesikali segridi kusebenza kwiileya ezintathu ezidityanisiweyo, nganye inefiziksi yayo, uqoqosho, kunye neendlela zokusilela. Uyaphoswa nabuphi na umaleko, kwaye uyaphoswa ukuba kutheni ibhetri esebenza ngokugqibeleleyo elebhu inokulahlekelwa yimali kwigridi{1}}okanye kutheni i-7.3 GW yaseCalifornia yogcino isacinywa ngo-2020.
Uluhlu loku-1: Inkqubo yePhysical (iKhemistri kunye neHardware)
Emazantsi kuhleli i-electrochemistry- eyona ntshukumo yeeyoni ezigcina kwaye zikhuphe amandla. Iibhetri zeLithium -zilawula apha nge-85% yesabelo semarike ngesizathu: ukuxinana kwamandla. Isingxobo esinye sokuthumela ngenqanawa sinokubamba i-3-4 MWh, ngokwaneleyo ukunika amandla amakhaya angama-1,000 ngeyure.
Isebenza njani ikhemistri:Ngaphakathi kwiseli nganye, i-ion ze-lithium zihamba phakathi kwee-electrode ezimbini nge-electrolyte engamanzi. Ngethuba lokutshaja, i-ion isuka kwi-cathode (ngokuqhelekileyo i-lithium iron phosphate okanye i-nickel manganese cobalt) ukuya kwi-graphite anode. Ngexesha lokukhutshwa, zibuyela umva, zikhupha ii-electron ezihamba kwisekethe yangaphandle ukuze zibe ngumbane oluncedo.
Ukusebenza kakuhle kohambo -lokubuya yi-85%-intsingiselo nge-100 kWh nganye oyigcinileyo, ufumana i-85 kWh. I-15% engekhoyo iba bubushushu, yiyo loo nto iinkqubo zolawulo lobushushu zimpompa into epholileyo ngeerekhi zebhetri 24/7. Xa oko kupholisa kungaphumeleli, ufumana okwenzekileyo e-Arizona ngo-2019: indawo ye-2 MWh yaqhuma, yonakalisa abacimi-mlilo abasibhozo.
Izinto eziphathekayo kwisistim yebhetri yegridi:
Iimodyuli zebhetri: Amakhulu okanye amawaka eeseli ezidityanisiweyo kunye. Indawo ye-100 MW inokuqulatha iiseli zebhetri ezingama-250,000 kwiinkonkxa ezininzi{4}}ezinobungakanani beerack.
Inkqubo yoLawulo lwebhetri (BMS): Ibeka iliso kumbane weseli nganye, ubushushu, kunye nemo yentlawulo. Yicinge njengenkqubo yemithambo-luvo{1}}ukuba iseli enye ishushu kakhulu okanye ayisebenzi kakuhle, i-BMS iyayenza yodwa phambi kokuba iingxaki zidlule.
Ulawulo lobushushu: Iinkqubo zokupholisa zamanzi okanye zomoya ezigcina amanqanaba okushisa afanelekileyo (ngokuqhelekileyo i-15-35 degree). Ukutenxa kobushushu beqondo nje eli-10 kunokunciphisa ubomi bebhetri ngama-20-30%.
Inkqubo yoGuqulo lwaMandla (PCS): I-bi-inverter ye-directional etshintsha phakathi kwe-AC (igridi) kunye ne-DC (ibhetri). Apha kulapho ubunjineli bombane buba nzima-igrid frequency kufuneka ithelekiswe ngokuthe ngqo ukuya ku-60 Hz, kwaye i-PCS iphatha amaxesha angamawaka ngesekhondi.
Ukucima umlilo: Iisistim zale mihla zisebenzisa -ukubonwa kwenqanaba (umfanekiso oshushu, izinzwa zerhasi) ezidityaniswe nezicinezeli ezicocekileyo. Emva kokuba uMzantsi Korea ufumene imililo yebhetri engama-28 phakathi kuka-2017{4}}2019, iinkqubo zokhuseleko ziye zangaxoxisani.
Inyani ebonakalayo:iibhetri zithomalalisa kunye nomjikelo ngamnye. Indawo inokuqalisa nge-100 MW kodwa emva kwemijikelo engama-6,000 (malunga ne-15 leminyaka yokuhamba ngebhayisikile yonke imihla), umthamo wehla ukuya kuma-80%. Uqoqosho lweprojekthi kufuneka luchaze oku kuhla{7}}nto leyo esizisa kuNqanaba 2.
Uluhlu 2: Inkqubo yoLawulo (iSoftware kunye noPhuculo)
I-Hardware yodwa ayinamsebenzi ngaphandle kobukrelekrele. Inkqubo yoLawulo lwaMandla (EMS) kunye noLawulo lokuLawula kunye nokuFumana iDatha (i-SCADA) yenza ingqondo ethatha isigqibo sokuba ihlawulise nini, ikhutshwe nini, kwaye ngaliphi izinga.
Izigqibo zexesha lokwenyani-ezenziwa yiEMS kwisekondi nganye:
Igridi yokujongwa rhoqo: Ukuba i-frequency yehla ngaphantsi kwe-59.95 Hz (intsingiselo yokuvelisa < imfuno), tofa amandla ngaphakathi kwe-140 millisecond
Iimpawu zexabiso: Ukutshaja kwi-25 yeedola / MWh nge-3am, ukukhupha kwi-$ 250 / MWh ngexesha lokuhlwa okuphezulu
Imeko yentlawulo yokwandisa: Ungaze uhlawule ngokupheleleyo okanye ukhuphe ukukhupha ukongeza ubomi bomjikelo (ngokuqhelekileyo usebenza phakathi kwe-10-90% umthamo)
Ukulinganisa ubushushu: Ukulungelelanisa imveliso yamandla ukuba nayiphi na imodyuli idlula amaqondo obushushu akhuselekileyo
Apha kulapho abantu abaninzi babhideka khona:iibhetri zegridi azifane zihlawulise kanye kwaye zikhuphe kube kanye ngemini. Ibhetri enye inokuthatha inxaxheba kwiimarike ezintlanu ezahlukeneyo ngaxeshanye:
Ukulawulwa rhoqo(iphendula{0}}kumahla-nyuka esibini)
Spinning reserves(imile ilungele ukusilela kwejenereyitha)
Umthamo wencopho(ukutshintsha izityalo zepeaker ezibizayo)
Amandla arbitrage(Thenga kancinci, thengisa phezulu)
Inkxaso yombane(ukufakela amandla asebenzayo ukuzinzisa amandla ombane wegridi)
IHornsdale Power Reserve ekuMzantsi Ostreliya ibonise oku ngokuqaqambileyo. NgoDisemba ka-2017, xa umzi-mveliso wamalahle wakhubeka ngokungalindelekanga kwi-intanethi, i-100 MW yebhetri yafaka amandla kwigridi nge-140 milliseconds{4}ngokukhawuleza kangangokuba iijenereyitha zamalahle zazingekayiboni ingxaki okwangoku. Eso santya sithintele ukuqhawuka kombane kulo lonke ilizwe.
Ingxaki yolungiselelo:Isoftware kufuneka ilinganise ukuthotywa ngokuchasene nengeniso. Ukuhamba ngebhayisekile ngokukhawuleza kuzuza imali eyongezelelekileyo kodwa kubulala ibhetri kwakamsinyane. Ii-algorithms ezisombulula oku zidlala umdlalo wepoker omninzi-oguquguqukayo apho babheja ngezigidi zeedola zokuthotywa kwebhetri ngokuchasene namaxabiso angaqinisekanga ombane kwixesha elizayo.
Iimodeli zokufunda ngoomatshini ngoku ziqikelela iimeko zegridi kwiiyure okanye iintsuku kwangaphambili, ukubeka iibhetri ekubambeni ixabiso eliphezulu. Uphononongo luka-2024 olwenziwa yi-MIT lufumanise ukuba i-AI{2}}ibhetri ephuculweyo ifumene i-15{4}}i-22% yengeniso engaphezulu kunomgaqo{{5}osekelwe kwiinkqubo-umahluko phakathi kwenzuzo kunye ne-inki ebomvu.
Uluhlu 3: Inkqubo yezoQoqosho (iNxaxheba kwiMarike kunye neNgeniso)
Apha kulapho ubunjineli budibana khona ne-capitalism, kwaye imisela ukuba iibhetri zegridi ziyakhiwa. Izibalo zikhohlakele: ibhetri ye-100 MW/400 MWh ixabisa malunga ne-120 yezigidi zeedola ukuyifakela. Kufuneka yenze ingeniso eyaneleyo yokuhlawula imali eyinkunzi, ihlawule iindleko zokusebenza, kwaye ibonelele ngembuyekezo kubatyali-zimali{5}lonke ngeli xesha ithoba isidima suku ngalunye.
Imijelo yengeniso (esekelwe kwidatha yokwenyani ye-ERCOT ukusuka kwi-2024):
Iinkonzo ezincedisayo(ummiselo wokuphindaphinda, oovimba): $40{1}}60/kW-nyaka kwiimarike ezifana neERCOT
Amandla arbitrage(ukubamba ukusasazeka kwexabiso): $15-30/kW-nyaka, kuguquguquka kakhulu
Iintlawulo zesakhono(ikhoyo): $10-25/kW-ngonyaka kuxhomekeke kwimarike
Udluliselo olumisiweyo(ukuphepha ukuphuculwa kwegrid): Isiza{0}}ngokukodwa, ingaba yi-$50{2}}100/kW-nyaka
Iyonke ingeniso enokwenzeka: $65-215/kW-ngonyaka, kuxhomekeke kuyilo lwemarike nendawo yebhetri. Ibhetri ye-100 MW ingenza i-R6.5-21.5 yezigidi zeedola ngonyaka-kodwa iindleko zokusebenza, oovimba bokuthotywa, kunye nenkonzo yetyala itya isiqingatha saloo nto.
Umceli mngeni: iimarike ziyazitya. Xa i-ERCOT ine-1 GW yeebhetri ngo-2022, ummiselo wefrequency wahlawula i-$80/kW-ngonyaka. Ngo-2024, nge-3.2 GW kwi-intanethi, amaxabiso ehle ukuya kwi-$45/kW-ngonyaka. Iibhetri ezingakumbi ezikhuphisanayo kwiinkonzo ezifanayo tyhala imida ezantsi{11}ubonelelo lwakudala kunye nemfuno.
Ixesha lezoqoqosho lidala isilingi enzima:Iibhetri ze-lithium zangoku{0}}zisebenza ngokoqoqosho kangangeyure ezi-2-6. Ngoba? Kuba ukusuka kwiiyure ezi-4 ukuya kwiiyure ezisi-8 kuziphinda kabini iindleko zebhetri kodwa ayiphindi ingeniso. Wongeza i-$ 600/kW kwiiseli zebhetri ukubamba mhlawumbi i-$ 100/kW kwi-arbitrage yamandla eyongezelelweyo.
Yiyo loo nto iingcaphephe zithetha nge "duration wedges"-lithium{1}}iphatha iion emfutshane{2}}ixesha (0{4}}8 iiyure), ukuhamba kwebhetri okanye umoya ocinezelweyo unokuzalisa-ubude bexesha (iiyure ezisi-8 ukuya kwezingama-24), kwaye ihydrogen okanye ugcino olushushu lunokuthi ekugqibeleni lusebenze ixesha elide (iintsuku ukuya kwiiveki). Akukho teknoloji enye iphumelela kuyo yonke indawo.
Ukubhideka kweMW vs MWh: Kutheni Amanani Abalulekile Omabini
Ukuba ufunde malunga neebhetri zegridi kwaye waziva ubhidekile yi "100 MW/400 MWh," awuwedwa. Olu phawu lubamba iipropati ezimbini ezahlukeneyo ngokupheleleyo:
Umthamo wamandla (MW)= Ikhawuleza kangakanani ukubiza okanye ukuyikhupha
Umthamo wamandla (MWh)= Inokuligcina ixesha elingakanani elo zinga
Yicinge njengombhobho wamanzi: Amandla sisidayamitha (isantya sokuhamba), amandla bubungakanani betanki. I-100 MW yebhetri ingatofa ngoko nangoko okanye ifunxe i-100 megawatts{3}}eyoneleyo kumakhaya angama-75,000{6}kodwa ixesha elingakanani kuxhomekeke kumlinganiselo we-MWh.
100 MW/200 MWh=2 iiyure ngamandla apheleleyo
100 MW/400 MWh=4 iiyure ngamandla apheleleyo
100 MW/800 MWh=8 iiyure ngamandla apheleleyo
Kutheni oku kubalulekile kwezoqoqosho:Isahlulo se-MWh siyabiza (ziiseli zebhetri ezo), ngelixa isahlulo se-MW sixabiso eliphantsi (umbane wamandla). Ibhetri yeeyure ezi-4 mhlawumbi ixabisa i-$300/kWh kwiiseli kunye ne-$200/kW yezixhobo zamandla. Ukuphinda kabini ubude bexesha (ukongeza iiseli ezininzi) kubiza ngaphezulu kokuphinda kabini amandla (ii-inverters ezinkulu).
Oku kwakhiwa kweendleko kungoko ubona iiprojekthi ezininzi "ze-100 MW/400 MWh" (4-ubude beyure) kodwa phantse akukho "100 MW/2,000 MWh" iiprojekthi (ixesha leeyure ezingama-20). Uqoqosho luqhawula ngaphaya kweeyure ze-6-8 ngeteknoloji ye-lithium-ion yangoku.
Ukusuka ekuChaselweni ukuya ekukhutshweni: Umjikelo wokuSebenza
Masihambe kusuku oluqhelekileyo lokusebenza kwigridi{0}}yezikali zebhetri eTexas, apho amaxabiso amandla aguquguquka kakhulu.
2:00 AM - Ukutshaja ngobusuku

Ilanga ayikakhuli okwangoku kodwa ii-air conditioners ziyaqalisa. Amaxabiso atsibela kwi-$45/MWh. Ibhetri ikhupha i-30% yamandla agciniweyo, ifumana i-$ 27 / MWh isasazeka (emva kwe-15% yokulahlekelwa kokusebenza kakuhle). Imeko yentlawulo yehla ukusuka kwi-90% ukuya kuma-60%.
10:00 AM - Isikhukula seSola, iSinyanzelo sokuZisa kwiGridi
Ukuvelisa amandla elanga amakhulu kutyhala amaxabiso angalunganga (-$5/MWh). Ibhetri itshaja ngokufanelekileyo. Ngequbuliso: iplanti yombane iyahamba ngaphandle kweintanethi. I-frequency yegridi yehla ukusuka kwi-60.00 Hz ukuya kwi-59.92 Hz kwi-800 millisecond.
Ialgorithm yokuphendula rhoqo kwebhetri ichonge ukutenxa kwaye ifake i-40 MW kwi-140 milliseconds{2}}ngokukhawuleza kakhulu kunokuba nayiphi na i-iturbine yegesi inokusabela. Ukuphindaphinda kuzinza kwi-59.97 Hz. Le mpendulo ye-140-millisecond ifumana ingeniso yokulawulwa rhoqo kwe-$ 4,800 ngaphantsi kwemizuzwana ye-10 yomsebenzi wangempela. Kulapho i-milliseconds ilingana ngokoqobo nemali.
6:00 PM - Incopho yangokuhlwa
Ukuntlitheka kwelanga xa ilanga litshona. I-AC ilayisha phezulu. Imfuno iyanda. Amaxabiso rocket ukuya $285/MWh. Ibhetri ikhupha umthamo opheleleyo we-100 MW kwiiyure ze-2.5, ikhupha ukusuka kwi-85% ukuya kwi-20% yesimo sentlawulo. Oku kuzuza malunga ne-$47,000 kwi-arbitrage yamandla kuphela.
Kodwa nantsi ixabiso elifihliweyo:oko kukhutshelwa kwencopho kusanda kudla i-0.02% yobomi bebhetri bubonke bomjikelo. Kuma-6,000 apheleleyo-ubomi bomjikelo, umjikelo ngamnye uxabisa malunga ne-$20,000 ekuthotyweni (ngebhetri eyi-$120M). Ibhetri ifumene i-47,000 yeedola kodwa "ichithe" i-20,000 yeedola kwiindleko zokutshintsha ezikhawulezileyo. Ixabiso leNet: $27,000, okanye malunga ne-$270/MWh.
11:00 PM - Ukutshaja okuKhanya, Ukuma okuGcinayo
Amaxabiso ahlala kwi-$32/MWh. Ibhetri itshaja kancinci ukuya kuma-45% umthamo, ibeka usuku olulandelayo. Igcina ubume bogcino ngobusuku, ifumana iintlawulo zesakhono sokufumaneka.
Uqoqosho lwemihla ngemihla lulonke: ~$55,000 iyonke ingeniso, thabatha i-$22,000 yeendleko zokuthotywa, thabatha i-$3,000 yeendleko zokusebenza=$30,000 intsalela yentlawulo yemihla ngemihla. Uqikelelo lonyaka: $10.9 yezigidi. Ngokuchasene ne-$120 yezigidi zeendleko zenkunzi, leyo yimbuyekezo yemali eyi-9.1% phambi kwenkonzo yetyala{14}}umda kodwa iyasebenza.
Itekhnoloji: Kutheni iLithium -Ion ilawula (Okwangoku)
Ugcino lwegridi ayiyoteknoloji enye kuphela. Ubuncinci iikhemistri zebhetri ezintandathu ziyakhuphisana, nganye ineempawu ezahlukileyo.
ILithium-Ion (85% yeSabelo seMarike)
Iintlobo ngeentlobo zeKhemistri:
ILithium Iron Phosphate (LFP):Ikhuselekile, ixesha elide-ukuphila (6,000-10,000 imijikelo), kodwa amandla aphantsi oxinaniso. Ilawula usetyenziso lwegridi-yile nto isetyenziswa nguTesla Megapack.
I-Nickel Manganese Cobalt (NMC):Uxinaniso lwamandla oluphezulu, kodwa umlilo{0}uqhelekile. Ukunciphisa ukusetyenziswa kwegridi emva kwesiganeko sase-Arizona.
Kutheni i-lithium-iyon iphumelele imakethi yokuqala:
Iindleko ziwile nge-90% phakathi kuka-2010-}2023 ngenxa yemveliso ye-EV isikali-up
Ixesha lokuphendula ngokukhawuleza (milliseconds)
Ukuthembeka okungqiniweyo kunye nezigidi zeebhetri ze-EV njengendawo yobungqina
Ukujikeleza -ubuchule bohambo lwe-85-92%
Isilingi:I-Lithium-iyoni ibetha imida yezoqoqosho nge-6-iyure ezisi-8. Ukugcina ixesha lonyaka, amanani awaze asebenze-uyakufuna malunga nama-200 eetriliyoni zeebhetri ukugcina iiveki ezi-6 zokusetyenziswa kwamandla e-US.
IiTekhnoloji ezizezinye ezisakhulayo
Iibhetri ezihambayo (vanadium redox):
I-Electrolytes egcinwe kwiitanki ezihlukeneyo, iphonswe ngamagumbi okuphendula. Inokulinganisa ubude bexesha ngaphandle kwamandla. Ubomi bomjikelo omde (imijikelo ye-10,000-20,000) kodwa ukusebenza okuphantsi (65-75%) kunye neendleko eziphezulu zangaphambili. Igqibelele kwi 8+ izicelo zeyure.
Iayini-iibhetri zomoya:
Phefumla umoya kwintsimbi yomhlwa, ujike inkqubo yokukhupha. Ultra-izixhobo ezitshiphu, ubude bulinganiswe ngeentsuku. Kodwa itekhnoloji ayikakhuli{3}}kuphela iiprojekthi zolingo ezikhoyo. Ingaguqula{5}}ugcino olude ukuba lurhwebo.
Isodium-iyoni:
Isebenzisa i-sodium eninzi endaweni ye-lithium. Okunokwenzeka ngama-20-30% ngexabiso eliphantsi kwisikali, ukhuselekile, kodwa ukuxinana kwamandla asezantsi. Abavelisi baseTshayina bahambisa iiprojekthi zokuqala zegridi ngo-2024-2025.
Okwesibini-iibhetri ze-EV zobomi:
Iibhetri ze-EV "zirhola" kwi-70-80% eseleyo umthamo-isasebenziseka kwizicelo zegridi. I-Redwood Materials yakha indawo engama-63 MWh kwiibhetri ezisetyenzisiweyo ze-EV ngo-Okthobha wama-2025, ibanga i-30-40% yokonga iindleko xa kuthelekiswa neebhetri ezintsha. Ulungiselelo lokulawula amawaka eentlobo ezahlukeneyo zebhetri zihlala zintsonkothile, kodwa ingqikelelo iyabonakala ukuba isebenza.
INyaniso yoKhuseleko: Imingcipheko yoMlilo kunye nokuNcitshiswa
Makhe sijongane nendlovu ekwisikhongozeli: iibhetri ze-lithium{0}} zingatsha. Iziganeko zinqabile kodwa ziyintlekele xa zisenzeka.
Iziganeko eziphambili ezibhaliweyo:
Epreli 2019, Arizona:I-2 MWh ibhetri ye-NMC iqhume ngexesha lokuyilungisa, yenzakalisa abacimi-mlilo abasi-8. Ongunobangela: ulawulo olulambathayo lobushushu kunye nokungangeni kwegesi ngokwaneleyo.
Epreli 2021, eBeijing:Umlilo we-25 MWh LFP ubulele abacimi-mlilo aba-2. Uphando lubonakalise impazamo ye-BMS ekuboneni ukubaleka kwe-thermal kwimodyuli enye.
EMzantsi Korea (2017-2019):Imililo engama-28 kuzo zonke iindawo zokugcina amandla ikhokelele ekuvalweni kweeyunithi ezingama-522 (ama-35% ofakelo). Umba oqhelekileyo: isithuba esingonelanga phakathi kweerekhi zebhetri kunye nokungangeni komoya kakubi.
Kutheni iibhetri zivutha (i-thermal runaway):
Xa iseli igcwele kakhulu, ishushu kakhulu, okanye yonakele emzimbeni, ukusabela kwangaphakathi kuyakhawuleza. Iqondo lobushushu liyenyuka, kukhawulezisa ukusabela ngakumbi{1}}umbono wengxelo entle. Kwi- ~ 130℃, i-electrolyte iqalisa ukubola, ikhupha iigesi ezinokutsha. Kwi- ~ 150℃, isahluli siyanyibilika, sibangele isiphaluka esifutshane sangaphakathi. Iqondo lobushushu spikes ukuya 600-800℃, ukuvutha iigesi. Ukusabela kusasazeka kwiiseli ezikufutshane.
Iseli enye engaphumelelanga inokuphumela kwirack yonke ngemizuzu. Yiyo loo nto iseli{1}}inqanaba lokujongwa kunye nemodyuli{2}}yokwahlulwa kwenqanaba ibalulekile.
Iinkqubo zokhuseleko zanamhlanje:
Iibhetri zegridi zanamhlanje zisebenzisa-ukhuseleko lweleya ezininzi ezizenza zikhuseleke kakhulu kuneenkqubo zangaphambili:
Iseli-inqanaba lokujongwa:I-BMS ilandelela amandla ombane kunye nobushushu beseli nganye nganye (amawaka kwisikhongozeli ngasinye), ibeka yodwa nakuphi na okudidayo
Umfanekiso oshushu:Iimodyuli ze-infrared zekhamera rhoqo kwimizuzwana emi-5, ukufumanisa iindawo ezishushu ngaphambi kokuba zibe yingozi
Ukufunyanwa kwerhasi:Izivamvo zokujonga ukucinywa kwegesi-(CO, CO2, i-volatile organics) eyandulela ukubaleka kwe-thermal
Ukuzibamba ngokwasemzimbeni:Iimodyuli ziqelelene nge-20-30cm ngokuqelelana ngomlilo{3}}izithintelo ezixhathisayo phakathi kweerekhi. Iindawo ezivaliweyo zomgangatho womkhosi zivavanyelwe ukumelana nokudubula kwangaphakathi.
Ukucinezelwa kwe-arhente ecocekileyo:Iinkqubo zisebenzisa i-3M Novec okanye izicinezeli ezifanayo ezicima umlilo ngaphandle kwamanzi (ezinokubangela ukusabela ngobundlobongela nge-lithium)
Ucimo oluzenzekelayo:Ukuba nayiphi iparameter igqithisa imida, inkqubo iyaqhawula kwigridi kwaye iqalise ukupholisa phantsi okulawulwayo ngaphakathi kwemizuzwana emi-2.
Inyaniso yeenkcukacha-manani:Ngeenkqubo zangoku zokhuseleko, izinga lokusilela limalunga ne-1 kwi-10,000 MWh-iminyaka yokusebenza. Oko kuthetha ukuba indawo ye-100 MWh inomngcipheko we-1% ngonyaka wesiganeko esimandundu sokhuseleko{7}}sekumngcipheko wokwenene ekufuneka ulawulwe nge-inshurensi kunye nesicwangciso sikaxakeka.
Ukutshintsha ukusuka kwi-NMC ukuya kwikhemistri ye-LFP nako kuphuculwe ngokumangalisayo ukhuseleko. Iqondo lobushushu elibalekayo le-LFP li- ~270℃xa lithelekiswa ne- ~210℃ye-NMC, kwaye i-LFP ayikhuphi ioksijini ngexesha lokubaleka kwe-thermal (ukwenza imililo ngokwayo{3}}ithintele kunokudubula).
Umngeni wokuDityaniswa kweGridi: AyisiyoPlagi-kwaye{1}}Dlala
Awukwazi ukuwisa nje i-100 MW yebhetri naphi na kwigridi kwaye ulindele ukuba isebenze. Udibaniso lufuna ukusonjululwa koqhagamshelo, uthumelo, kunye nemingeni yentatho-nxaxheba yemarike ethatha iminyaka emi-2{3}}iminyaka emi-4-ixesha elide kunokwakha isibonelelo.
UQhagamshelwano loNxibelelwano oluNxibisayo
E-US, umgca we-interconnection queue (uluhlu lokulinda lokuxhuma kwigridi) lube yingxaki ebalulekileyo. Ukusukela ngasekupheleni kuka-2024, ngaphezulu kwe-2,700 GW yokuvelisa kunye neeprojekthi zokugcina zilindile{6}}ngokwaneleyo ukunika amandla ilizwe lonke kabini.
Ixesha eliphakathi lomgca: iminyaka emi-4 ukusuka kwisicelo ukuya ekuvunyweni koqhagamshelo. Kutheni ixesha elide kangaka?
Izifundo zempembelelo yenkqubo:Abasebenzisi begridi kufuneka babonise indlela ibhetri ye-100 MW eya kuchaphazela ngayo amandla ombane, amaza ombane, kunye nokuhamba okuhambayo kuthungelwano lwengingqi. Oku kufuna uhlalutyo oluphucukileyo lokuhamba kwamandla kwaye kunokuthatha iinyanga ezili-12-18.
Uphuculo losasazo:Ukuba izibonelelo zegridi azikwazi ukumelana nomthamo omtsha, abaphuhlisi kufuneka bahlawulele uhlaziyo. Iprojekthi yebhetri ye-150 yezigidi zeerandi inokuthi iqalise i-40 yezigidi zeedola kuphuculo lothumelo, itshabalalise uqoqosho lweprojekthi.
Uphononongo lolawulo:Iimvume zokusingqongileyo, ulwamkelo lwasekhaya, uphawu lomcimi-mlilo{0}}luvaliwe, uhlolo lwekomishini eluncedo. Ngamnye wongeza iinyanga.
Imiba yokubeka ngobuchule:Iibhetri ezibekwe kwiibottlenecks zothumelo zibonelela ngexabiso elongezelelweyo ngokuthomalalisa ukuxinana, ngamanye amaxesha ufumana i-$50-100/kW-ngonyaka owongezelelweyo. Kodwa ezi ndawo ziphambili zinqabile kwaye zikhuphisana kakhulu.
Ukuntsonkotha koThatho-nxaxheba kwiMarike
Abaqhubi begridi abohlukeneyo (ii-ISO) banemithetho eyahlukileyo ngokugqithisileyo yokuthatha inxaxheba kwebhetri:
ERCOT (eTexas):
Ukukhawuleza-ukuphendula iinkonzo ezincedisayo kwimakethi, ukusebenzisana-ukwandisa amandla kunye noovimba, akukho marike yomthamo (onke amandla{2}}kuphela). Iibhetri ziqhuba kakuhle apha-yiyo loo nto i-Texas ine-3.2 GW efakiweyo nangona iimarike zingamiselwanga.
I-CAISO (eCalifornia):
Iimfuno zokwanela kwezibonelelo (isibophelelo somthamo), usuku oluntsonkothileyo-ngaphambili kunye{1}}lokwenyani{1}}kwiimarike zexesha, iingxaki zokulinganisa amandla ombane kunye nendawo yesolar co{2}}. Intsonkothile kodwa inengeniso ukuba uhamba ngayo ekunene-7.3 GW ifakiwe.

Buyisela imilinganiselo:
Intlawulo elula: iminyaka engama-26 (ayinakwenzeka)
Kodwa linda{0}}yongeza inkuthazo...
Ityala leRhafu yoTyalo-mali (30% ngo-2024): -$35.7M ucutho lwexabiso lwangaphambili
Inkunzi ehlengahlengisiweyo: i-83.3 yezigidi zeedola
Intlawulo elula nge-ITC: iminyaka eyi-18.3
I-IRR iquka i-ITC kunye nexabiso elishiyekileyo: ~8-9%
Ngumda lowo. Imbuyekezo ye-8-9% isusa ngokukhawuleza amazinga omqobo kwiiprojekthi zeziseko zophuhliso. Kungenxa yoko le nto:
Uninzi lweebhetri zegridi zixhomekeke kwinkxaso-mali(ITC, izibonelelo zikarhulumente, iikhontrakthi eziluncedo) ukuphumeza imbuyekezo eyamkelekileyo
Abafuduki bokuqala bathathe ezona ziphumo zihleXa i-ERCOT inogcino oluncinci, ummiselo wokuphindaphinda wahlawula i-$80/kW-ngonyaka. Ngo-2025, iyakuba kufutshane ne-$40/kW-ngonyaka njengoko unikezelo lukhukula kwimarike.
Ukupakishwa kwengeniso kubalulekileIiprojekthi ezixhomekeke kumthombo omnye wengeniso ziyasilela. Kufuneka ubambe i-3-5 imijelo yexabiso eyahlukeneyo ukwenza amanani asebenze.
Ukuthotywa kubulala iiprojekthi ezibuthathaka:Ibhetri ethoba i-20% ngokukhawuleza kunemodeli ijika iprojekthi engenangeniso ibe yilahleko yemali. Kulapho ubunjineli obugqwesileyo bohlula abaphumeleleyo kukungabikho kwemali.
Ixesha lezoQoqosho: Udonga lweyure ezi-4 kunye nento elandelayo
Uninzi lweebhetri zegridi oziva ngazo zithelekelelwa nge-4-yeyure yeyure. Oku akunasizathu-kulapho uqoqosho luqhekeka khona.
Kutheni iiyure ezi-4 zibe ziqhelekileyo:
Iipateni zexabiso zombane zemihla ngemihla zinencopho enye enkulu{0}}eqhele ukuhlwa (6-9 PM). Isizukulwana seSolar sidala "ijika ledada" apho kufuneka ugcine iiyure ezi-3-4 zelanga eligqithisiweyo lasemini ukuze liphume ngexesha lokuhlwa. Ukubamba ukuba ukujika kwexabiso lemihla ngemihla kuhlawulela ibhetri. Kodwa ukugcina iiyure ezisi-8, ezili-12 okanye ezingama-24? Izibalo ziyahlukana.
Ubunzima bexesha:
Ukusuka kwiiyure ezi-4-ukuya kwiiyure ezisi-8-ubude bexesha kufuna ubungakanani bebhetri obuphindwe kabini ngelixa amandla ombane ahlala engatshintshi. Wongeza i-$400/kW kwiiseli zebhetri ukuze ufumane imali eyongezelelweyo ye-$80/kW yonyaka kwi-arbitrage yamandla-utyalo-mali olubi. Ingeniso eyongeziweyo kwiiyure ze-5-8 iphantsi kakhulu kuneeyure ze-1-4.
Oku kudala isilingi yendalo. Kwi-lithium - ion, indawo emnandi yezoqoqosho ziiyure ezi-2-6. Ngaphandle koko, udinga itekhnoloji ezahlukeneyo.
Yintoni evala isithuba sobude bexesha?
8-24 iiyure (ixesha eliphakathi):Iibhetri eziqukuqelayo, ugcino lwamandla omoya ocinezelweyo, i-lithium enokuthi iqhubele phambili -iion kunye neendleko zeseli eziphantsi kakhulu
Iiyure ezingama-24-100 (ixesha elide):Ugcino lweHydrojeni, ugcino lwe-thermal, kunokwenzeka ukuba i-iron{0}}iibhetri zomoya ukuba zirhweba
Ixesha lonyaka (iiveki ukuya kwiinyanga):Ugcino lokumpontshwa kombane wamanzi, ihydrogen, okanye akukho nto (ibiza kakhulu nangabuphi na ubuchwephesha bangoku)
ISebe lezaMandla lase-US linenyathelo elide lokuGcinwa kwaMandla ekujoliswe kuko<$0.05/kWh storage cost for 10+ hour duration. Current lithium-ion is ~$0.15-0.20/kWh for 4-hour storage. That 3-4× cost reduction is needed to make long-duration storage economically viable at scale.
Eyona-isinyanzelo sehlabathi: Systems with >I-90% yamandla ahlaziyekayo adinga iiveki zokugcina ukuphatha "dunkelflaute" (igama lesiJamani leeveki ezingenamoya, ezinamafu). Asinabo ubuchwephesha obusebenza ngokwezoqoqosho kule nto okwangoku. Yiyo loo nto iingcaphephe zithetha nge-60-80% yokungena okunokuhlaziywa njengenyani ekufutshane{5}}yexesha ekujoliswe kulo, ukuvala izikhewu ngokuveliswa kwerhasi yendalo eguqukayo de iteknoloji yokugcina ixesha elide ivuthwe.
Ikamva: IiNdlela eziPhumayo eziLungisa iGridi ngokutsha
Okwesibini-Iibhetri zoBomi zifike kwisikali
Kangangeminyaka, iingcali zaqikelela ukuba iibhetri ze-EV ziya kuphoseka kwindawo yokugcina igridi emva kokuthatha umhlala-phantsi kwiimoto. Ngo-2025, iyenzeka ekugqibeleni. I-Redwood Materials' 63 MWh yesibini -isibonelelo sobomi sibonisa imodeli: iibhetri ze-EV zigcina umthamo we-70-80% xa usetyenziso lwemoto lurhola, kodwa luninzi logcino lwegridi olumileyo apho ubunzima kunye nevolumu ingenamsebenzi.
Uqoqosho lwesibini-ibhetri zobomi:
Ibhetri entsha: $ 200-250 / kWh
Ibhetri ye-EV ehlaziyiweyo: $100-150/kWh (ibandakanya ukuqokelela, ukuvavanywa, ukupakishwa kwakhona)
Ugcino: 30-40%
Umceli mngeni uhlala ungowolungiselelo kunye ne-heterogeneity. Ngokungafaniyo neebhetri ezintsha apho uodola iiyunithi ezifanayo, iibhetri zobomi yesibini zingumxube weekhemistri, ubungakanani, kunye neemeko zokuthotywa. I-Redwood iyisombulule le nto ngenkqubo yolawulo lwebhetri "yesiguquli jikelele" esilungelelanisa iintlobo ezahlukeneyo zebhetri{3}}ezinzima kodwa ezisebenzayo.
Njengoko ukwamkelwa kwe-EV kuya kukhawuleza, ngo-2030 kunokubakho i-1-2 2 TWh yeebhetri ze-EV ezidla umhlala-phantsi ezifumaneka ngonyaka-ezoneleyo ukunika amandla i-US yonke iintsuku ezininzi. Eli gagasi lokubonelela liza kubumba kwakhona uqoqosho lokugcinwa kwegridi.
UPhuculo lwe-AI luhamba phambili
Abasebenzisi bogcino lwebhetri bahamba ngaphaya komgaqo olula{0}osekelwe kwiimodeli zokufunda koomatshini abaqikelela amaxabiso, iimeko zegridi, kunye nokwandisa ukuthotywa{1}}vs-urhwebo lwengeniso{3}}isaphulelo{4}}ngexesha lokwenyani.
Yintoni eyenziwa yi-AI:
Uqikelelo lwamaxabiso olusekwe kwimozulu, iipateni zembali, kunye nokutshintsha kweemarike
Ibhidi ezenzekelayo kwiimarike ezininzi ngaxeshanye
Ukuthotywa-ukuthunyelwa kolwazi (ukuhamba ngebhayisekile kancinci xa imida ibhityile)
Ugcino oluqikelelwayo (ukubona iiseli ezisilelayo phambi kokusilela kwentlekele)
Uphononongo lwe-MIT luka-2024 lufumene i-AI{1}}ibhetri eyongeziweyo ifumene i-15{3}}i-22% yengeniso engaphezulu kuneenkqubo zemveli-ukuguqula iiprojekthi ezingephi zibenengeniso. Lindela ukuthunyelwa kwe-AI kuya kuba zizithinteli zetafile ngo-2026.
IziCwangciso zaMandla oMbane: UkuHlanganisa iibhetri ezisasazwayo
Endaweni yokwakha ii-megaprojects ezisembindini, ezinye izinto eziluncedo zidibanisa amawaka eebhetri zasekhaya (ezifana neTesla Powerwalls) zibe "zizityalo zamandla abonakalayo." Inkqubo yokunciphisa umthwalo ongxamisekileyo yaseCalifornia yahlanganisa i-17,000 yeebhetri zasekhaya ngo-2024, ibonelela nge-275 MW yomthamo oguquguqukayo ngexesha lamaza obushushu.
Izinto eziluncedo:
Akukho zithintelo zothumelo (iibhetri sele ziqhagamshelwe kwinqanaba lokuhambisa)
Ukusasazwa okuKhawulezayo (akuvunyelwa ukuba kusetyenziswe indawo-yemilinganiselo)
Iindleko zokufakela ezisezantsi (i-piggyback kufakelo lwelanga)
Imingeni:
I-Cybersecurity (ukulungelelanisa amawaka ezixhobo kudala indawo yokuhlaselwa)
Ukudinwa kwabathengi (abantu abathandi ukukhwela ibhayisekile ngexesha likaxakeka)
Umthamo osezantsi (iibhetri zendawo yokuhlala zinezinye izinto eziphambili ezinje ngamandla agcinayo)
Ngo-2030, oomatshini bamandla abonakalayo banokumela i-20-30% yomthamo wogcino wase-US uwonke-ungatshintshi iibhetri zobungakanani bomsebenzi kodwa ziyancedisana nazo.
Ukuzivelela koYilo lweMarike
Iimarike zangoku zombane zayilwa xa iijenereyitha yayizizityalo zefosili ezinokuthunyelwa. Iibhetri azihlali ngokucocekileyo{1}ngabathengi, iijenereyitha, kunye neenkonzo zegridi zonke ngaxeshanye. Uhlaziyo lwemarike luyaqhubeka:
Co-ukuphucula amandla kunye neenkonzo ezincedisayo:Ukuvumela iibhetri ukuba zitshintshe phakathi kweemarike ngokuguquguqukayo
Ugcino{0}}iimveliso ezithile:Njenge "impendulo yefrikhwensi ekhawulezayo" evuza amaxesha okuphendula ama-millisecond
Imithetho yokuvunywa kwamandla:Ungakanani "umthamo oqinileyo" obonelelwa yibhetri yeeyure ezi-4? (Ingxoxo eqhubayo)
I-FERC Order 841 (2018) ivule iimarike ezithengisayo ukuze zigcinwe, kodwa ukuphunyezwa kuhlala kumdaka. Lindela ukuqhubeka koyilo lwentengiso ngo-2030 njengoko ugcino lukhula ukusuka kwi-2% ukuya kwi-10-15% yomthamo wegridi.
Imibuzo ebuzwa qho
Zihlala ixesha elingakanani iibhetri zesikali segridi phambi kokuba zifune ukutshintshwa?
Iibhetri zanamhlanje ze-lithium iron phosphate zihlala zihlala kwi-6,000-10,000 imijikelezo epheleleyo ngaphambi kokuthotywa kwe-80% yomthamo wokuqala. Ngokuhamba ngebhayisikile yonke imihla, yiminyaka eyi-15-25 yobomi bokusebenza. Nangona kunjalo, ukukhwela ibhayisekile okundlongondlongo kulawulo lwamaxesha amaninzi kunokunciphisa oku ukuya kwiminyaka eli-10-15. Iiprojekthi ezininzi zebhajethi yokwandiswa kwebhetri rhoqo emva kweminyaka eyi-7-10 ukugcina umthamo we-nameplate.
Kutheni singenakusebenzisa iibhetri zegridi ugcino lwamandla onyaka?
Ezoqoqosho. Ukugcinwa kwexesha lonyaka kufuna ukubamba amandla iiveki okanye iinyanga. Ibhetri yeeyure ezi-4 ixabisa ~$300/kWh efakiweyo. Ukugcina amandla iinyanga, uya kufuna i-100× iipakethi ezinkulu zebhetri, ukutyhalela iindleko ukuya kumgangatho weenkwenkwezi. Ngomxholo: Iiveki ze-6 zokugcinwa kwamandla e-US ziya kufuna malunga ne-$ 200 yezigidigidi kwiibhetri (malunga ne-10 × i-US GDP). Obunye ubuchwephesha obufana ne-hydrogen bunokuthi ekugqibeleni busebenze kugcino lwamaxesha onyaka, kodwa sineminyaka ukusuka kwimpumelelo yezoqoqosho.
Ngaba iibhetri zesikali segridi ziyingozi kuluntu olukufutshane?
Umngcipheko usezantsi kodwa awukho-zero ngeenkqubo zangoku. Iibhetri ze-Lithium iron phosphate (LFP), ngoku zisemgangathweni wegridi, zikhuselekile kakhulu kuneekhemistri ezindala. Ubushushu bobushushu bobushushu buphezulu, kwaye abayikhuphi ioksijini ngexesha lokusilela. Amaziko anamhlanje abandakanya ukubonwa kwe-thermal, ukubonwa kwegesi, kunye noxinzelelo lomlilo ococekileyo. Umyinge wokusilela ngokweenkcukacha-manani umalunga ne-1 kwi-10,000 MWh{8}}iminyaka. Xa kuthelekiswa, izityalo ezikwincopho yerhasi yendalo zinomngcipheko wogqabhuko-dubulo, kwaye izityalo zamalahle zikhupha ungcoliseko lomoya oluqhubekayo. Lilonke, ugcino lwebhetri olulungiswe ngokufanelekileyo lukhuselekile kunezinye iindlela ezininzi.
Ngaba iibhetri zinokuthatha indawo ngokupheleleyo yezityalo zerhasi yendalo?
Ngexesha elifutshane-incopho zexesha (2{2}}iiyure ezi-4), ewe{6}}kwaye ngexabiso eliphantsi. Ngeemfuno ezandisiweyo zokunyuka (8+ iiyure) okanye i-snaps ebandayo ehlala iintsuku, hayi. Ibhetri ye-lithium yangoku{10}}ibethwe kwimida yezoqoqosho ngaphaya kweeyure ezi-6. Yiyo loo nto iingcali zijonga iibhetri njengezo zincedisayo, zingatshintshi ngokupheleleyo, ukuvelisa igesi. Njengoko ukungena okuhlaziyekayo kusanda, siya kufuna ugcino lweentsuku ezininzi (iibhetri zokuhamba, i-hydrogen, umoya ocinezelweyo) ukuphelisa ngokupheleleyo ugcino lwefosili.
Ingakanani igridi yesikali sogcino lwebhetri eneneni inciphisa ukukhutshwa?
Kuxhomekeke ukuba ibhetri iyisusa ngantoni na. Ukuba ibhetri igcina amandla elanga ebenokucuthwa ngenye indlela kwaye ithathe indawo yokuveliswa kwerhasi yendalo, unciphiso olukhutshwayo lukhulu kakhulu-kumalunga ne-0.4{5}}0.5 kg CO2 ngekWh nganye yokuveliswa kwerhasi ephetshiweyo. Nangona kunjalo, ukuba ibhetri ihlawulisa kwigridi yamalahle{6}}enzima kwaye ikhutshwe kamva, unciphiso lokukhutshwa kwentsalela luncinci ngenxa yelahleko yokuya nokubuya ngokufanelekileyo. Ixabiso lokwenyani livela ekuvumeleni ukungena okuphezulu okunokuhlaziywa ngokusombulula ingxaki yokuphazamiseka. Uphononongo lubonisa ukuba ukugcinwa kwegridi kwenza i-10-15% amandla ongezelelweyo ahlaziyekayo nge-GW nganye ye-4-iyure yokugcina efakiwe.
Kwenzeka ntoni kwiibhetri zegridi ekupheleni{{0}zo{1}}zobomi?
Uhlaziyo lwangoku lufumana kwakhona i-90-95% yezinto ezixabisekileyo (i-lithium, icobalt, i-nickel) kwiipakethi zebhetri. Iinkampani ezifana ne-Redwood Materials kunye ne-Li{3}}Cycle zakha ii-gigawatt-zeendawo zokurisayikilisha. Inkqubo yokuhlaziya ibandakanya ukuqhekeza iiseli, ukwahlula izixhobo nge-hydrometallurgical okanye iinkqubo zepyrometallurgical, kunye nokuzicokisa zibuyele kumgangatho webhetri. Izixhobo ezisetyenzisiweyo zinokwenza iibhetri ezintsha kwi ~ 70% yeendleko kunye ne-60% yokukhutshwa kwemigodi enyulu. Njengoko i-wave yokuqala yeebhetri zegridi ifikelela kumhlalaphantsi (2030-2035), ukulungiswa kwakhona kweziseko zophuhliso kuya kubaluleka ekugcineni ukugcinwa kwekhonkco lokubonelela.
Kutheni amanye amazwe aneebhetri ezininzi zegridi ngelixa ezinye ziphantse zingabikho?
Izinto ezintathu ezilawulayo: ukungena kwamandla ahlaziyekayo, uyilo lwemarike, kunye nenkuthazo karhulumente. I-Texas neCalifornia zinesizukulwana esiphezulu selanga / somoya (ukudala amathuba e-arbitrage), iimarike zentengiso eziphucukileyo (impendulo ekhawulezayo evuzayo), kunye nemigaqo-nkqubo exhasayo (iikhredithi zerhafu, izigunyaziso). Ngeli xesha, amazwe afana neKentucky okanye iWest Virginia aneegridi zamalahle-ezinzima (ukuguquguquka kwexabiso eliphantsi), iimarike eziluncedo ezilawulwayo (ukhuphiswano olulinganiselweyo), kunye nezigunyaziso ezinokuthi zihlaziyeke kancinci. Kude kube zonke izinto ezintathu zilungelelaniswe, ukuthunyelwa kogcino kuhlala kuncinci. I-Federal incentives (ITC) iyanceda, kodwa imigaqo yelizwe{5}}ihlala ibalulekile.
Umgca osezantsi: Ugcino lunika amandla igridi ecocekileyo, kodwa sikwi-10% kuphela apho
Ukugcinwa kwebhetri yesikali segridi kukhule ukusuka ku-zero ngo-2013 ukuya kwi-26 GW e-US ngo-2024-isantya esichukumisayo. Oko kwanele ngoku ukunika amandla malunga ne-20 yezigidi zamakhaya kwiiyure ezi-4. Kodwa umxholo ubalulekile: i-US iyonke amandla okuvelisa yi-1,230 GW. Iibhetri zimele nje i-2% yaloo nto.
I-Arhente yezaMandla yaMazwe ngaMazwe iqikelela ukuba sidinga i-35× ngaphezulu kogcino lwegridi ngo-2030 ukubetha iithagethi zemozulu{2}}ukukhula ukusuka kwi-26 GW ukuya ngaphezulu kwe-900 GW kwiminyaka emithandathu. Oko kongeza ugcino oluninzi rhoqo emva kweenyanga ezimbini kunokuba bekunjalo ngo-2020.
Ngaba ingenzeka? Imizila ithi mhlawumbi. Iindleko zehle ngama-90% kule minyaka ilishumi idlulileyo. Amaxesha okufakela ehlile ukusuka kwiinyanga ezili-18 ukuya kwiinyanga ezi-6. Amakhonkco obonelelo ayavuthwa. Ukulungiselela i-AI yongeza i-15-20% yexabiso elingaphezulu kwibhetri nganye. Iibhetri ze-EV zobomi besibini zenza imithombo emitsha yokubonelela ngexabiso eliphantsi.
Kodwa imingeni emithathu ihlala ikhona:
Ubude bexesha: Sidinga 10+ ugcino lweyure ukutyhala ngaphaya kwe-80% evuselelekayo. Itekhnoloji ikhona (iibhetri zokuhamba, intsimbi{3}}umoya, i-hydrogen) kodwa iindleko zihlala ziyi-2-3× phezulu kakhulu. Ugqatso luyafuneka, hayi uphuculo olongezelelekileyo.
Isikali: Ukwakha i-900 GW yokugcina kufuna i-$ 400-500 yezigidigidi kwi-capital kunye nokunyuka okukhulu kwe-lithium, i-nickel, kunye ne-cobalt mining. Amatyathanga obonelelo kufuneka akhule nge-10× ngelixa kwangaxeshanye ufaka umbane izithuthi nayo yonke enye into. I-Bottlenecks ibonakala ingenakuthintelwa.
Uyilo lwemarike: Iimarike zangoku zombane azakhelwanga iipropati ezizodwa zogcino. Uhlaziyo lolawulo luhamba kancinci kuneteknoloji. Ukupakishwa kwexabiso kuyanceda, kodwa ukulungiswa ngokutsha kweemarike kuya kufuneka njengoko ukugcinwa kukhula ukusuka kwi-2% ukuya kwi-15-20% yomthamo opheleleyo.
Ifiziksi iyasebenza. Uqoqosho luya apho. Into ehlala ingaqinisekanga kukuba izithintelo zamaziko (imvume, uqhagamshelo, imigaqo yemarike) inokulungelelanisa ngokukhawuleza ngokwaneleyo. Ugcino lwegridi ayilonyango olungummangaliso kumandla acocekileyo{3}}bubuchwephesha obavumelayo ukuba sibubeke kwimpucuko{4}}yokutshintsha isikali. Nokuba sibaleka ngokukhawuleza ngokwaneleyo ayizocaca de kube ngu-2030.
