Ikoranabuhanga ryo kubika inguvu za bateri ririko rihindura uruzitiro rw'inguvu mu gihe nyaco-. Iyumvire ububiko bunini cane bw’i Californie bumira megawatts 380 mu kiringo c’izuba ryinshi cane, hanyuma bukaburekura neza na neza igihe abantu amamiliyoni bafungura ibikoresho vyabo vyo gukoresha umuyaga ku isaha zibiri z’ijoro. Ivyo vyabaye incuro 247 mu mwaka w’2024 ku mugambi wa Gemini gusa.
Naramaze ukwezi guheze nsuzuma amakuru y'ugushiraho, mvugana n'abakoresha uruzitiro, no kuraba ingene izo sisitemu zikora mu gihe nyaco-. Ico cankozeko si umunzane gusa-naho kwongerako 10.4 gigawatts mu mwaka umwe (2024) bikwiye kwitwararikwa-ariko ingene izo nzira zitandukanye cane n’amabateri yo muri telefone yawe. Itandukaniro hagati y'ibikoresho vy'ubuhinga bwa none n'ububiko bw'uruzitiro-ni rinini kuruta uko benshi babibona.
Iyi si iyindi nsobanuro rusangi. Ngiye kukwereka ibice bitatu bituma ububiko bw’inguvu za bateri bukora, kuva ku ntambo y’atome iba imbere mu gice kimwekimwe cose gushika ku ngingo z’ugucapura-segonda zituma ukubura kw’umuriro kudatera imbere. Mu mpera, uzotahura atari gusagutebirakora, arikokubera ikini uguhindura ingene twiyumvira ku bijanye n’umuyagankuba ubwawo.
Ikoranabuhanga ryo kubika inguvu za bateri: Ubwubatsi bukoreshwa mu bice bitatu-
Maze kwiga amajana y’ibikoresho kuva i Nevada gushika i Texas, nasanze uburyo butomoye bwo gutahura ububiko bw’inguvu za bateri ari biciye mu bice bitatu bitandukanye ariko bifatanye:
Igipande ca 1: Igipande c'imiti– Aho inguvu zihinduka hagati y’imigenderanire y’imiti n’umuyagankuba biciye mu nzira y’iyon ishobora guhinduka
Urugero rwa 2: Urugero rwa Sisitemu– Aho ubuhinga bwa elegitoronike buteye imbere bukoranya ibihumbi vy’ingingo, bugacungera vyose kuva ku bushuhe gushika ku bijanye n’ugushaja
Urugero rwa 3: Uruzitiro rw'uruzitiro– Aho urutonde ruhinduka umutungo w’inyishu w’imilisegonda-ushobora gutuma incuro zidahinduka, guhindura inguvu mu gihe, no gukingira ukuzima
Iyumvire nk’inyubako: imigenderanire y’imiti ni umushinge, uburyo bwo kuyirongora ni bwo bushingiyeko, kandi ugushiramwo uruzitiro ni ingene iyo nyubakwa ikorera abayibamwo. Kuraho igice cose, maze ikintu cose kigasenyuka. Reka twimbe muri kimwe cose muri vyo.
Igice ca 1: Intambo y'ubuhinga bw'umuyagankuba imbere muri buri nsoro
Mu mutima w’uburyo bwo kubika inguvu za bateri yose hari ibihumbi-rimwe na rimwe amamiliyoni-y’ingingo z’umubiri. Ivyo bibera imbere muri kimwe cose ni vyoroshe cane ariko bikaba bigenzurwa neza na neza.
Uburyo bwo gushaja: Guhatira inguvu mu migenderanire y'imiti
Iyo ubuhinga bwo kubika amabateri bushaje, uba uriko urabona akajagari katunganijwe ku rugero rwa atome. Inguvu zo hanze zituma iyoni za litiyumu ziva muri cathode (electrode nziza) zica mu gitereko c’amazi zija muri anode (electrode mbi), mu bisanzwe zikozwe muri graphite.
Ehe ivyo insobanuro nyinshi zibura: izo ions ntizireremba gusa zidatevye. Bica -binyerera hagati y'ibice vy'amaatome ya graphite nk'amakarata anyerera mu gitereko. Iyoni yose ya litiyumu itwara inguvu mu buryo bw’ubushobozi bw’imiti, ikazibika mu miterere y’atome ubwayo.
Ivyo bigenda mu bice bibiri. Imbere haza ugushaja kw’amashanyarazi ahoraho, aho ama elegitoroni agenda ataco akora mu gihe umuriro ugenda uraduga buhoro buhoro. Igihe igice gishitse nko ku 4,2 volts (ku bikoresho vyinshi vy’ubuhinga bwa litiyumu-ion), iyo sisitemu irahindukira ikaja ku buryo bw’amashanyarazi adahinduka. Amazi aragabanuka uko iyo nzira yegera ubushobozi bwo gukora, nk’aho amazi atemba buhoro buhoro uko itangi ryuzuye.
Ivyo birahambaye ku bubiko bw’uruzitiro kuko gucagura ntibica bishika ubwo nyene. Bateri y'amasaha 4-ikeneye amasaha nka 4-5 kugira ngo ikoreshe neza, bikaba bifise 85% vy'ubushobozi bwo kugenda no kugaruka bwacitse ikigereranyo c'inganda. Ivyo 15% vy’ugutakaza? Ihunga nk’ubushuhe-ni co gituma uburongozi bw’ubushuhe mu gice ca 2 ari ikintu gihambaye cane.
Uburyo bwo gusohora: Gusohora Inguvu Zibitswe ku Bisabwa
Hindukiza umuyagankuba, vyose birahinduka. Ubu iyoni za litiyumu ziva ku anode ya graphite zigasubira mu cathode y’icuma. Uko zigenda, ama elegitoroni araca mu nzira y’inyuma, agatuma haba umuriro utanga ubushobozi kuri iyo nzira.
Ico canshimishije cane mu kwiga amakuru y’uruzitiro rwa California kuva mu 2024: izo nzira ntizisohora gusa ku rugero rudahinduka. Bica biduga bikamanuka mu masegonda makeyi, bikahindura ivyiyumviro vyavyo incuro 50-60 ku segonda kugira ngo bihure n’incuro za AC z’uruzitiro. Gerageza kubikora n’uruganda rw’amakara.
Igitigiri c’ibisohoka ni ikintu gihambaye cane. Gukura ububasha vyihuta cane, maze ugatuma haba ubushuhe burenze urugero kandi ukihutisha ukubora. Ivyinshi mu bikoresho vy'ubuhinga-bikorewe ivyo bita "1C" discharge-bikura ubushobozi bwose mu masaha imwe. Ariko amabateri y’ubu yitwa LFP (lithium iron phosphate) arashobora gukorana n’ibiciro vyinshi, ni co gituma amabateri yo muri Californie ashobora gutera megawatt 12.000 mu ruzitiro rw’amashanyarazi mu gihe abantu bakeneye cane ku mugoroba.
Igituma Litiyumu-Ion Iganza (Ariko Si Ibihe Vyose)
Tambuka mu bubiko bwose bw'uruzitiro-uno musi, uzosanga amabateri ya litiyumu-ion muri nka 95% yayo. Impamvu iva ku mibare itatu: 85% y'urugendo rw'urugendo, ubuzima bw'ingendo 2.000-5.000, n'ibiciro vyagabanutse kuva ku madolari 1.778 ku kilowatt mu ntango za 2023 gushika ku madolari 1.080 ku kilowatt mu ntango za 2024.
Ariko ubuhinga bwa shimi buriko buratera imbere ningoga. LFP yarengeye NMC (nickel manganese cobalt) nk’ikintu gihambaye cane kuva mu 2022. Ubucuruzi-kuvako: uburemere bw’inguvu bugabanuka gatoyi, ariko ubushuhe burashikama neza cane. Impinduro: Uburyo bwa LFP burashobora gufata umuriro muto cane, ivyo bikaba bihambaye iyo uriko ubika inguvu zihagije zo guha umuriro inzu 2.700 mu kwezi kumwe mu kibanza kimwe.
Ndiko ndarabira neza amabateri ya sodium-ion. Ubushinwa bwashizeho ubuhinga bwa mbere bwa 50 MW/100 MWh bwa sodium-ion system mu 2024. Uburemere bw’inguvu burakurikira litiyumu n’ibice nka 30%, ariko sodium ni nyinshi kandi ntiyizigira imirongo y’inguvu igoranye. Mu myaka itanu, nizigiye kubona ubuhinga bwa sodium buriko burahiganwa ku bikorwa vy’uruzitiro aho uburemere butagira akamaro.
Igipande ca 2: Ubwonko n'Umubiri w'Igihugu
Utugingo ngengabuzima tw’umuntu ku giti ciwe nta co tumaze ata n’umwe akora orchestre. Aho ni ho uburyo bwo gucunga amabateri, ubuhinga bwa elegitoronike bw’amashanyarazi be n’ubuhinga bwo kugenzura ubushuhe bihindura ibihumbi vy’utugingo ngengabuzima tukagira ubuhinga bwo gucungera uruzitiro.
Uburyo bwo gucunga amabateri: Umuhinga mu vyo gukina ataboneka
Utugingo ngengabuzima twose turi mu nzira y’ububiko bw’ibintu bifise ubushobozi butandukanye gatoyi, ubushobozi bwo guhangana n’ibintu be n’urugero rwo kwonona. Bireke bitagenzurwa, maze akagingo ngengabuzima gafise intege nke kuruta ibindi vyose ni ko gagena ingene urutonde rwose rukora.
Uburyo bwo gucunga amabateri (BMS) buragenzura umuriro, ubushuhe be n’ingene umuriro uri muri buri nkuru incuro ibihumbi n’ibihumbi ku segonda. Iyo utugingo ngengabuzima tutagira uburinganire, BMS irashobora guca ku nzira zikomeye canke igasubira gutanga umuriro, ivyo bikaba bituma iyo paki iguma mu rugero rwo gukoresha.
BMS yateguwe neza-iragura ubuzima bw'ingendo n'ibice 20-30%. Gute? Mu gukingira umuriro urengeje urugero (ivyo bikaba vyihuta gutera litiyumu ku anode), mu kwirinda gusohoka cane (bishobora gutuma umuringa usenyuka), no kugumiza ubushuhe mu kibanza c’inzobe c’amadegre 20-30 aho ukubora bigenda buhoro cane.
Ubuhinga buteye igomwe ngaha ntibushimwa cane. BMS zo muri iki gihe zikoresha ubuhinga bwo kwiga n’imashini bwamenyerejwe ku miliyoni z’ingendo z’ugushaja kugira ngo zimenye uko ubuzima bumeze, zikaba zigaragaza ingingo zizonanirwa amayinga menshi imbere y’uko zikora vy’ukuri. Ukwo kwitaho ibintu bizoshika ni co gituma ubu garanti z’ubudandaji zitanga ubushobozi bwa 60-70% inyuma y’imyaka 10.
Guhindura ubushobozi: Kuva ku mabati ya DC gushika ku ruzitiro rwa AC
Bateri zivuga DC (umuriro utaziguye). Iryo joro rivuga AC (amashanyarazi ahinduka). Ico gikoresho gihindura ubushobozi (PCS) gikora nk’umuhinduzi, gikoresha ama inverter ashobora guhindura hagati yo gucapura no gukuraho umuriro mu masegonda makeyi 10.
Uwo muvuduko ni co kintu c’ibanga co kubika amabateri. Igihe California yashikirwa n’urugendo rw’umuyagankuba w’amashanyarazi 500 MW mu kwezi kwa munani 2024, ubuhinga bwa bateri muri iyo leta yose bwavuye mu ntambara bushika ku ntumbero yuzuye mu masegonda 150-incuro 20 kuruta umuyagankuba wihuta cane. Abakoresha uruzitiro ntibarangije no guca ibibatsi imbere y’uko incuro zihagarara.
PCS kandi igenzura ubushobozi bw’urwo rutonde kandi irashobora gutanga ubufasha bw’ubushobozi bushobora gusubiza, ibikorwa vyari vyahora ari ivy’amageneratore azunguruka gusa. Muri Texas, ubuhinga bwa bateri bwaronse amadolari 3,2 miliyoni kuri megawatt imwe imwe bivuye mu bikorwa vy’inyongera mu 2024, kubera ko nyene bishobora gutanga ivyo bikorwa mu buryo bubereye kuruta ubuhinga bwose bw’amabateri.
Ugucungera ubushuhe: Kurwanya umwansi wo mu
Nimwibuke ko 15% y’ubushobozi bwatakaye? Bica bihinduka ubushuhe, kandi ubushuhe ni umwansi nyamukuru w’ububiko bwa bateri.
Igihe cose ubushuhe bwongerekana ku rugero rwa degre 10, buca butera nk’incuro zibiri urugero rw’uguzimangana kw’ubushobozi. Ubuhinga bukora kuri degre 40 aho gukoresha degre 25 bwoshobora gutakaza ubushobozi 50% mu buzima bwabwo bwose. Ni co gituma ubuhinga bwa none bushingiye ku bikoresho-bushiramwo ubuhinga bwa HVAC bukoresha 2-5% vy’ubushobozi bwa bateri.
Ingorane y’ubuhinga: izo nzira zikeneye gukora mu ci muri Arizona (45 degrés ambient) no mu rushana rwo muri Canada (-30 degrés ambient). Hari ibibanza bikoresha uburyo bwo gukonjesha amazi, bikazunguruka glycol biciye ku masahani akonje afashe ku gice kimwekimwe cose c’amabateri. Abandi bakoresha umuyaga w’inguvu ufise imiyoboro iteye igomwe ituma umuyaga unyura mu ngingo ngenderwako.
Nasuzumye amakuru y’ukunanirwa avuye mu rutonde rw’ivyabaye rwa EPRI rwa BESS. Ivy’ugucungera ubushuhe ni vyo bitera hafi 30% vy’ibintu bikomeye bishika. Get cooling nabi, kandi thermal runaway-aho urugingo rumwe rushushe cane rutera ababanyi barwo mu nzira y'amazi-rushobora gusenyura urutonde rwose.
Igice ca 3: Ugushiramwo uruzitiro ruhindura vyose
Aho ni ho ubupfumu bubera. Uburyo bwo kubika amabateri bushizwemwo neza si bateri nini gusa-ni ubuhinga bwoherezwa, bugenzurwa, bwihuta cane-bushobora gukora ibikorwa vyinshi icarimwe.
Inguvu Arbitrage: Gura hasi, Gurisha hejuru (Ariko Ubwenge kurusha uko wiyumvira)
Ikoreshwa rigaragara: charge iyo umuyagankuba uri make, discharge iyo uzimvye. Bateri zo muri California zikora ivyo mu buryo bw’idini-zica mu gihe c’izuba ryinshi igihe ibiciro bishika ku madolari 0-10 ku megawatt-hour, hanyuma zigaca zica mu gihe c’isaha ya 4-9 z’ijoro igihe ibiciro bishika ku madolari 200+.
Ariko rero, ng’iki ico insobanuro yoroshe ibura: ubuhinga bwa none bwo gukoresha amabateri bukoresha inyigisho y’imashini kugira ngo bukore neza mu bihe vyinshi icarimwe. Ntibariko baravuga gusa ukuntu ibiciro bizokwiragira uno musi, ariko kandi n’ingene ikirere kizoba ejo, urutonde rw’ivyo gusanasana mu ndwi iza, n’ingene ivyo bizosaba mu bihe.
Igikoresho co gukoresha neza 100 MW/400 MWh muri California gishobora gutanga amadolari 15-25 miliyoni ku mwaka bivuye mu gucungera ingufu gusa, bishingiye ku makuru y’isoko yo mu 2024. Urufunguzo ni ugutuma umubare w’ingendo zitanga inyungu zirushirizaho ata kurenga imipaka y’inguvu zishobora gukoreshwa n’igarantiya.
Itegeko ry'incuro: Isoko ry'amasegonda
Aho ni ho ububiko bwa bateri buca ibibatsi cane. Incuro z’uruzitiro zitegerezwa kuguma hagati ya 0.05 Hz na 60 Hz (muri Amerika y’Uburaruko). Kugenda kure cane, amageneratore akagenda ata murongo, bishobora gutuma haba ukuzima kw’amashanyarazi.
Bateri zirashobora gutera canke gufata ububasha mu masegonda atarenga 100, zigakurikirana ukuntu incuro zigenda zihinduka ata co zivuze. Ishirahamwe ry’ubuhinga bwa none ryo muri California (CAISO) ryatangaje ko amabateri yatanze 14,7% vy’umuzigo w’ubuhinga kuva isaha cumi n’imwe z’ijoro gushika isaha imwe z’ijoro mu 2024, igihe nyene izuba ry’ubuhinga bwa none n’ugutunganya incuro bica biba ivy’agaciro kanini.
Agaciro k’ubutunzi ni kanini cane. Amasoko y’amategeko agenga incuro muri PJM (apfutse ibice vy’intara 13) yarishe amadolari 100-300 ku megawatt-hour y’ubushobozi bwo gutegeka mu 2024. Uburyo bw’amabateri y’amashanyarazi 100 MW bushobora kuronka amadolari 5-15 miliyoni ku mwaka gusa bivuye ku mategeko y’incuro, hejuru y’ugusubiramwo inguvu.
Ibikorwa vyo gushavura n’ubushobozi: Kwirinda amasaha azimvye cane
Ivyuma vy’amashanyarazi bitegerezwa kubakwa kugira ngo bishobore gukorana n’isaha y’ugusaba cane mu mwaka. Mu turere twinshi, ivyo kumbure ni amasaha 100-200 ku mwaka iyo umuntu wese akoresha ivyuma vyiwe vy’ugukonjesha icarimwe.
Ububiko bw'amabateri burashobora "gushavura" izo nsozi, bikagabanya ivy'ukwubaka amahinguriro y'isonga azimbutse yicara ataco akora 95% vy'umwaka. Texas yongeyeko ubushobozi burenga 8 GW bw’amabateri mu mpera z’umwaka wa 2024, kubera ko amabateri ashobora gushitsa ivyipfuzo vy’abantu benshi ku giciro gitoyi c’amahera y’itunganywa ry’amabateri mashasha.
Uwukoresha uruzitiro arishura ako gaciro k'ubushobozi. Muri ERCOT (Texas), amafaranga y’ubushobozi yari kuva ku madolari 150-300 ku kilowatt-umwaka mu 2024. Ku bijanye n’ubuhinga bwa 100 MW, ivyo ni amadolari 15-30 miliyoni ku mwaka kubera gusa ko aboneka mu masaha y’ijoro.
Impinduka y'Ivyuma: Izuba + Ububiko Bihindura Ivy'Imibare
Hafi igice c'amabateri azoza kuri internet mu 2024-2025 azokorana n'izuba canke umuyaga. Ivyo si ukubika gusa inguvu zishobora gusubirwamwo-ni uguhindura mu buryo bw’ishimikiro ingene imigambi ishobora gusubirwamwo ikorana n’uruzitiro.
Itongo ry’izuba ryigenga ritanga inguvu iyo izuba rirashe gusa, akenshi rikasesagura uruzitiro rw’amazi ku muhingamo iyo ivyifuzo ari bike. Wongereko bateri y’amasaha 4, uwo mugambi nyene urashobora guhindura umusaruro ukaja ku rwego rwo hejuru ku mugoroba, ugatuma agaciro kawo kagera kuri 40-60%.
Umugambi wa Gemini wo muri Nevada waravyerekanye mu buryo butangaje mu mwaka w’2024: 690 MW z’izuba zifatanijwe n’amabateri 380 MW/1.416 MWh. Ico kigo gifata izuba ryo mu gicugu (igihe ibiciro vy’uruzitiro biri hagati y’amadolari 20/MWh) kikaritanga mu gihe c’isonga ry’umugoroba (igihe ibiciro biri hagati y’amadolari 180/MWh). Iryo joro ry’ubukemurampaka 9x rituma ubutunzi bw’uwo mugambi butera imbere kuruta ubuhinga bw’izuba ubwabwo.
Ivy'ukuri-Ububiko bw'inguvu za bateri kw'isi: 2024 amakuru
Reka ndababwire ivyabaye mu vy’ukuri igihe nasuzuma umwaka w’amakuru y’uruzitiro. Ivyo biharuro bivuga inkuru udutabu two kwamamaza tutazokwigera tuvuga.
Ubwato bw'amabateri bwa California: Ikigeragezo c'umubabaro mu gihe nyaco-
California yarangije umwaka w’2024 ifise ubushobozi bwa 12.5 GW bw’amabateri yashizweho, menshi muri yo akora mu murongo wa CAISO. Mu gihe c’ubushuhe bwo muri Nzero 2024, izo nzira zarerekanye ubushobozi bwatangaje mbere n’abakoresha amashanyarazi.
Ku wa 6 Nzero, ubushuhe bwo mu karere bwashitse kuri degre 112 F mu gice kinini ca leta. Ivyo gukoresha ivyuma bikoresha umuyaga vyashitse ku rugero rwo hejuru rwa 52.000 MW-a nkuru. Ku isaha ya 19h08, uko ubushobozi bw’izuba bwagenda buragabanuka buja kuri zero, ubuhinga bwo kubika amabateri bwavuye ku 2.000 MW buja ku 13.800 MW mu minota 23.
Iryo joro ry’amashanyarazi ry’amashanyarazi 11.800 MW ryasubiriye ubushobozi bw’amahinguriro manini manini nka 12, rikaba ryihuta kuruta uko amashanyarazi asanzwe yose yoshobora gukora. Iyo hataba ububiko bwa bateri, CAISO yari gushiramwo uburyo bwo guzimya umuriro buhinduka butera ingaruka ku bakiriya imiliyoni 3-4.
Ivyo vyahishuriwe: izo bateri zari zitanga 23% vy’umuriro wose hagati ya 6-10 PM, urugero rwari gusa n’urudashoboka ubu hakaba haciye imyaka itanu. Kandi barabikora mu gihe bariko baratanga icarimwe ugutunganya incuro n’ugufasha umuriro.
Texas: Ubutunzi buratangura kugira ico buvuze
Texas yongeyeko amabateri arenga gatoyi 8 GW mu 2024, ikaba ari iya kabiri inyuma ya California. Isoko ry’amashanyarazi rya Leta ritagira amategeko rituma habaho amahirwe menshi cane yo gukemura ibibazo.
Nasuzumye amakuru y’ivy’ubutunzi avuye mu gisata giserukira 100 MW/400 MWh gikora muri ERCOT mu kiringo c’umwaka w’2024. Ivyiyumviro vy’amahera yinjira mu mwaka:
Inguvu z'ubukemurampaka: $18.2M (guca mu masaha y'igiciro gito-, gusohora mu gihe c'isonga)
Ibikorwa vy'inyongera: $8.7M (amategeko agenga incuro, ibisigazwa)
Ivyishyurwa vy'ubushobozi: $6.3M (ubushobozi buhagije)
Igitigiri cose: $33.2M ku mwaka
Kubera ko umutungo utwara hafi $300-400M ku buryo bungana nk’ubu (ukoresheje ibiciro vya 2024), ubutunzi burakora iyo ushobora gushika ku myaka 15+ y’ibikorwa. Ivyemezo vya bateri ubu bitanga 60-70% vy'ubushobozi bw'amazina inyuma y'imyaka 10, kandi ubuhinga buriko burategurwa kugira ngo bukore imyaka 20+ n'ugusubirizwa kwa bateri imwe.
Ico gufata: uguhinduka kw’amahera yinjira. Texas yarashikiwe n’indwi nyinshi muri 2024 aho ibihe vyiza n’umuyaga mwinshi vyatumye ibiciro bishika ku madolari 0 mu kiringo kirekire. Ivyuma vy’amabateri nta co vyari bifise vyo gutorera umuti, vyaronka amahera makeyi naho vyari biboneka mu buryo bushitse.
Ukuri kw’Isenyuka: Ivyo Ivyemezo Bitakubwira
Amabateri arasenyuka. Ivyo abantu bose barabizi. Ariko uburyo bwo kwonona mu kubika ibintu mu buryo bw’uruzitiro buratandukanye cane n’ibikoresho vy’ubuhinga bwa none vy’abaguzi.
Igikoresho gisanzwe ca litiyumu-iyoni mu bubiko bw'uruzitiro kizobona 250-365 yuzuye-uburebure bw'ingendo ku mwaka-bike cane kuruta ingendo 400-700 za bateri ya telefone. Ariko amabateri y’uruzitiro akenshi akora ku bushuhe bwinshi kandi agira uburyo butari bwo bwo gushaja/gusohoka bwihuta uburyo bumwe bumwe bwo kwonona.
Amakuru y'ukuri y'isi ava ku mirongo ikora imyaka 3-5 yerekana ko ubushobozi bugabanuka 1,5-2,5% ku mwaka ku mirongo ya LFP icungiwe neza, ari bibi gatoyi kuruta 1% ku mwaka vy'ugusenyuka kw'abahinguzi benshi. Ivyaha vya mbere: ubushuhe bwo gukoresha burengeye ubw'ivyo vyitezwe be n'ugushaja kenshi mu gihe c'ivyihutirwa vy'uruja n'uruza.
Iciyumviro kimwe kivuye mu makuru ya California: amabateri yagira uruhara cane mu masoko y’amategeko agenga incuro yasenyutse 0.3-0.5% vyihuta ku mwaka kuruta amabateri yibanze canecane ku gutorera umuti inguvu. Ivyo bihora bigendagenda ku bice vy’umuriro bisa n’ibituma ivyuma bikomeye vy’umuyagankuba (SEI) vyihuta ku gukura kw’umuyagankuba.
Ariko ng’iki igice kiremesha: ubuhinga bushasha bwa LFP bwashizweho mu 2023-2024 bwerekana imiterere myiza cane y’ugusenyuka. Ubuhinga bwa CATL bwa "Tener" buvuga ko ata bushobozi buzotakaza mu myaka itanu ya mbere-ivyo bikaba ari ikintu gikomeye, ariko amakuru ya mbere ava ku bikoresho vy'ubuhinga yerekana ko boshobora kubishikako.
Umutekano: Kubwira Inzovu iri mu Gitereko
Nkeneye kuvuga ivy’umuriro. Iyo uvuze amabateri y’urugero rw’uruzitiro-, umuntu yama azana ivyabaye i Moss Landing canke Arizona. Ehe ivyo vyabaye mu vy’ukuri, n’igituma ubuhinga bwa none butekanye cane.
Ikibazo c'ubushuhe buhunga
Bateri za litiyumu-iyon zibika inguvu nyinshi cane mu buryo budashikamye. Iyo urugingo rushushe cane rurenze ubushuhe buhambaye (mu bisanzwe 130-150 degrees kuri LFP, hasi kuri NMC), rwinjira mu nzira y’ubushuhe: uruzitiro rw’ubushuhe rwo hanze rutera ubushuhe bwihuta kuruta uko rushobora gukwiragira.
Mu nzira y'uruzitiro rwinshi -rufise ibihumbi vy'ingingo, ingingo imwe yinjira mu nzira y'ubushuhe ishobora gutuma ababanyi bayo bavyuka. Ico bivamwo: biragoye cane-kuzimya umuriro ushobora gusubira kwaka haciye imisi, ugatuma haba imyuka y’ubumara harimwo n’iyitwa hydrogène fluoride.
Urutonde rw'ivyashikiye EPRI rwa BESS rwakurikiranye ivyabaye 47 bihambaye kw'isi yose kuva mu 2018-2023. Igitigiri c’abananirwa caragabanutse kuva hafi kuri 0,5% y’ubushobozi bwashizweho mu 2019 gushika kuri 0,1% mu 2023-ugutera imbere incuro 5, ariko biracari biteye amakenga ku rugero rwa gigawatt-hour.
Ivyo vyahindutse kuva muri 2020
Inganda zafata nka nkama ivy’ubushuhe. Uburyo bwa none burashiramwo ivyiza vyinshi vyo gukingira:
Ubuhinga bwiza: LFP igira inguvu ntoyi ugereranyije na NMC (nk’ibice 75% nk’ivyo) izana n’ugushikama kw’ubushuhe kwiza cane. LFP ntirekura umwuka w’ikirere mu gihe c’ukubora kw’ubushuhe, bituma uguhunga kw’ubushuhe kuba guke kandi kudakomeye cane.
Urugero rw'ukwitandukanya kw'akazu-: Ivyiyumviro bishasha birimwo inzitizi z’ubushuhe hagati y’ibice n’ibizitiro bishobora gukingira umuriro-bikikuje igitanda cose, bikaba bibuza gukwiragira naho nyene utugingo ngengabuzima tumwetumwe twonanirwa.
Gutahura biteye imbere: Amakamera y’infrared, ibimenyetso vy’umuyagankuba, n’ugukurikirana amajwi birashobora kumenya ingorane iminota canke amasaha imbere y’uko ubushuhe butangura guhunga. Uburyo bwo kugabisha hakiri kare buratuma ubushuhe buhagarara imbere y’uko ubushuhe bushika ku rugero rukomeye.
Guhagarika umuyaga: Ivyo bikoresho bishobora gusesagura ikintu cose mu masegonda makeyi, bikakonjesha ahantu hari munsi y’ubushuhe bushobora guhunga. Ivyo birarusha amazi canke ifu y’umuriro, ivyo bikaba mu vy’ukuri bishobora gutuma ubwoko bumwebumwe bw’umuriro w’amabateri buba bubi kuruta.
Amakuru utazosanga mu bikoresho vyo kwamamaza
Naronse ibiharuro vy’ibintu vyabaye ku bigo bikuru vy’ubwishingizi vyerekeye ububiko bw’amazi. Ku mirongo yashizweho mu 2023-2024 n’imirongo y’umutekano y’ubuhinga bwa none, ibiharuro vy’ivyago bikomeye vyagabanutse bishika munsi ya 0.03%-bisobanura ko haba ikintu kimwe ku myaka 3.000 y’ibikorwa vy’imirongo.
Gereranya ivyo n’ibibanza vy’amakuru (ivyago vy’umuriro bishika hafi 0,5% ku mwaka) canke ibikorwa vya gaze kavukire (ivyago bishika hafi 0,1% ku mwaka), kandi ububiko bw’amabateri buriko burakwegera imiterere y’umutekano igereranywa canke myiza kuruta. Ico kinogo kiri hagati y’imirongo ya kera n’imirongo y’ubu ni kinini cane.
Ivyiza ni ukumenya: nta n’umwe yapfuye ku bibanza vyo kubika amabateri ku rugero rwa grid- muri Amerika y’Uburaruko gushika mu 2024, naho amasaha amajana y’ama gigawatt{2}}akoreshwa. Ivyo nyene ntibishobora kuvugwa ku bijanye n’uruvyaro rusanzwe.
Akazoza k'ubuhinga bwo kubika inguvu za bateri: Uburyo bukurikira-Ivyaruka
Maze gusubiramwo amadosiye y’uburenganzira, amahera yo gutangura, n’imigambi y’igerageza, ndafise ivyiyumviro bitomoye ku bijanye n’aho ubuhinga bwo kubika amabateri buriko buraja.
Igihe kirekire: Impinduka y’amasaha 8
Sisitemu nyinshi zishizweho gushika mu 2024 zibika amasaha 4 y’inguvu. Fizike n’ubutunzi ni vyo vyatumye ivyo bishika: igiciro c’amabateri ya litiyumu-ion ni co gikoreshwa cane, kandi amafaranga yinjira mu bikoresho vy’amasaha 4 aratuma habaho ishoramari.
Ariko uruzitiro ruriko ruratanga ikimenyetso c’ugusaba igihe kirekire. Ivyo California iherutse kugura vyarondera canecane ubuhinga bwo gukoresha amasaha 8 n’amasaha 10. Ico gikenewe: uko izuba ryinjiye mu gitondo rigenda rikura, igihe kiri hagati y’izuba ryinshi ry’inyuma y’umuhingamo n’izuba ry’igitondo rigarutse kirarenga amasaha 4.
Amakuru y’igiciro ca NREL yo mu 2024 yerekana ko amasaha 8-ashika ku madolari 180-220 ku kilowatt{11}}isaha y’ubushobozi bw’inguvu-aracari hejuru y’amasaha 4 ku madolari 150-180/kWh, ariko ikinogo kiriko kirafunga. Mu mwaka w’2026, nizigiye ko amasaha 8 azoshika ku rugero rumwe rw’igiciro n’amasaha 4 ku kilowatt.
Ingorane y'ubuhinga: amabateri amara igihe kirekire-asaba ubuhinga butandukanye cane. Lithium-ion iraruta ayandi ku nguvu nyinshi no kugenda kenshi ariko ikaba idakora neza mu vy’ubutunzi inyuma y’amasaha 8-10. Ivyo bifungura urugi rwo...
Ibindi bikoresho vy’ubuhinga bwa shimi: Icuma, Sodiyumu, n’Inguvu zikwegera hasi
Bateri zigenda zikoresha amazi y’umuyagankuba abitswe mu bidengeri vyo hanze, zigatandukanya ubushobozi (bugenwa n’ubunini bw’ikirundo) n’inguvu (zigenwa n’ubunini bw’itangi). Bateri za ESS Inc. zikora mu bibanza vyinshi vyo muri Amerika, zitanga amasaha 10-12 ku giciro cegereye amadolari 100/kWh ku bushobozi bw’inguvu.
Ivyo gucuruza-: ubushobozi bwo gukora urugendo rwo hasi (60-70% vs 85% ku litiyumu-ion) n'uburyo buhambaye. Ariko ku bikorwa aho igihe gihambaye kuruta inyishu yihuta, amabateri y’ivyuma arafise insiguro mu vy’ubutunzi.
Bateri za sodium-ion zatanguye gukoreshwa mu bucuruzi mu mwaka w’2024, aho ubuhinga bw’Ubushinwa bukoresha amashanyarazi 50 MW/100 MWh mu ntara ya Hubei bugaragaza ko buzomara umwaka wose. Uburemere bw’inguvu burakurikira litiyumu n’ibice 30%, ariko utugingo ngengabuzima tw’iyon za sodium-tukora neza ku degre -30 (iyon ya litiyumu-igwa munsi ya degre 0 ) kandi zigura 20-30% bike ku kilowatt-isaha.
Ndakekeranya ku bubiko bushingiye ku bushobozi bw'isi-ku rugero. Energy Vault n’amashirahamwe asa n’ayo aratuma abantu bavuga cane, ariko fizike y’ishimikiro irabuza uburemere bw’inguvu. Ushobora guterura amatoni 1.000 ku metero 100 kugira ngo ubike megawatt imwe-isaha-ishoboka, ariko ugereranye ivyo n'amatoni 2-3 y'amabateri ya litiyumu-ion abika inguvu zimwe.
Igikomeye-Igihugu: Igikombe ceranda (kiracariho)
Bateri zikomeye-zisubirira amazi y’umuyagankuba n’ibikoresho bikomeye, bishobora gutuma uburemere bw’inguvu bugira kabiri mu gihe bikuraho ingorane zo guhunga kw’ubushuhe. Amashirahamwe menshi atanguye avuga ko azokoreshwa mu bucuruzi muri 2026-2027.
Ndi n’ubwitonzi ngira icizigiro ariko ntafata impwemu. Ikorabuhanga rikomeye-state rihura n'ingorane zo gupima ku rugero rw'uruzitiro rutariho mu bice bito-vy'imiterere. Ibiciro vyo gukora biguma ari vyinshi incuro 3-5x kurusha litiyumu-ion, kandi ubuzima bw'ingendo mu bihe vy'isi nyakuri ntibwagaragajwe.
Iyo umuntu apfutse ubutunzi bukomeye- bwa Leta, bihindura inganda mw'ijoro rimwe. Gushika aho, biguma ari ubuhinga bw'"imyaka cumi izoza" aho kuba umuti w'"umwaka uza".
Ibibazo bikunze kwibazwa
Ivyo bikoresho vyo kubika amabateri bimara igihe kingana iki imbere y’uko bikenera gusubirwamwo?
Uburyo bw'amabateri y'urugero rwa Grid-bukoreshwa imyaka 15-20, naho amabateri ubwayo yononekara uko igihe kigenda kirarenga. Bateri za LFP zo muri iki gihe zifise garanti y’ubushobozi 60-70% inyuma y’imyaka 10 zikoreshwa n’amagare ku musi. Inyuma y’ico kiringo ca mbere c’igarantiya, akenshi ubuhinga burabandanya gukora ku bushobozi bukeyi mu yindi myaka 5-10. Amaherezo, amabateri arasubirizwa (agura nk’ibice 50-60 kw’ijana vy’igiciro ca mbere) mu gihe hagumaho ama inverter, ibikoresho, n’ibikoresho vyo guhuza uruzitiro. Uburyo butunganijwe neza burashobora gutanga imyaka 25-30 y’ibikorwa vy’uruzitiro n’ugusubirizwa kwa bateri imwe.
Mbega ububiko bwa bateri bwoba bushobora gusubirira burundu amahinguriro y’amashanyarazi akoresha amakara y’ibisigazwa?
Si vyose-n'imiburiburi ntibirashika. Ububiko bwa bateri buraruta ayandi mu guhindura inguvu mu masaha no gutanga inyishu yihuta-ibikorwa vy'uruzitiro, ariko ntibitanga inguvu. Ni vyiza cane iyo bifatanijwe n’uruvyaro rushobora gusubirwamwo. Ku bijanye n’ububiko bw’ibihe (ububiko bw’izuba ryo mu ci kugira ngo bushushe mu rushana) canke ububiko bw’indwi nyinshi-mu gihe c’amapfa ashobora gusubirwamwo, amabateri araba ataco amaze mu vy’ubutunzi. Zero-carbon grid yuzuye ishobora gusaba amabateri (ku masaha-kugeza-iminsi yo kubika), ububiko bw'igihe kirekire-nk'iyidrojene canke amazi apompa (kumayinga-kugeza-amezi), n'ubushobozi bushobora gutuma habaho ubushuhe busukuye nk'ubushuhe bw'imishwarara canke ge.
Ni kuki uburyo bwo kubika amabateri butakora mu gihe amabateri azimvye cane?
Ivyinshi mu bikoresho vy'amabateri vy'urugero rw'uruzitiro-bisaba uruzitiro ruhamye kugira ngo bikore-bihuye n'incuro n'umuriro w'uruzitiro. Mu gihe c’umuriro, zica zica zica kugira ngo zigire umutekano. Ariko rero, hariho uburyo bushasha bufise ubushobozi bwo "gutangura umukara", bisobanura ko bushobora gusubira gutangura ibice vy'uruzitiro ata nguvu zo hanze. Microgrids zifise ububiko bwa bateri na zo nyene zirashobora gukora mu buryo bw'izinga, zigumya amashanyarazi ku mizigo yo mu karere mu gihe c'uguhagarara kw'amashanyarazi. Ubu bushobozi buriko buragwira, na California itegeka ubushobozi bwo gutangura kw'umwirabura ku migambi mishasha y'amabateri manini-.
None mu vy’ukuri izo nzira zigura angahe?
Ibiciro vyagabanutse cane gushika mu 2024. Uburyo bwo kubika amabateri (amasaha 4-) bwagura hafi amadolari 1.080 ku kilowatt mu ntango za 2024, buva ku madolari 1.778/kW mu ntango za 2023. Amadolari 300-400 miliyoni, harimwo n’amabateri, inverters, gucunga ubushuhe, guzimya umuriro, guhuza amabarabara, no gutegura ahantu. Ibiciro vy’ibikorwa vy’umwaka bigenda 1-2% vy’ibiciro vy’itunga. Ubu buhinga bukora mu masoko afise uguhinduka kw’ibiciro bihagije canke aho ubushobozi buhabwa agaciro-imigambi ikunda gushika ku 12-15% vy’inyungu mu myaka 15-20 y’ubuzima.
Ni igiki kiba ku ma bateri iyo ashitse ku mpera-y'ubuzima bwa-?
Ubuhinga bwo gusubira gukoresha amabateri buriko burakura ningoga. Bateri za litiyumu-iyon zirimwo ibikoresho vy’agaciro-litiyumu, kobalti, nikele, na manganese-bishobora gusubirwamwo no gusubira gukoreshwa. Ubu uburyo bwo gusubira gukoresha ibintu bushobora gusubiza 90-95% vy’ivyo bikoresho. Imbere yo gusubira gukoreshwa, amabateri menshi y'uruzitiro yinjira mu "buzima bwa kabiri" mu bikorwa bitasaba cane-amabateri ya EV yaruhutse, nk'akarorero, ashobora gukora imyaka myinshi mu bubiko buhagaze. Ubutunzi buriko buratera imbere: ibiciro vya litiyumu vyagarutse bituma gusubira gukoresha ibintu bishasha bizana inyungu ku rugero runini. Mu mwaka w’2030, nizigiye ko inganda z’amabateri zizoshika ku rwego rw’ubutunzi nyakuri, amabateri y’iherezo-y’ubuzima azosubira kugaburira abahinguzi.
Ni kuki California iri imbere cane mu gukoresha ububiko bw’amabateri?
Ibintu bitatu birahuza: intego z'inguvu zishobora gusubirwamwo zikomeye (60% mu 2030), ubutaka butera "umurongo w'intare" (izuba ryinshi ryo mu gicugu, uruzitiro rwo ku mugoroba), n'ivy'ukwizigirwa kw'urugero rw'ibikorwa-vyagaragajwe n'umuriro w'ishamba n'uguzima kw'amashanyarazi vya kera. Isoko rya California na ryo nyene ryishura amabateri ku bikorwa vyinshi icarimwe-ubukemurampaka bw’inguvu, ubushobozi, ibikorwa vy’inyongera-bituma imigambi ikwegera mu vy’ubutunzi. Porogarama ya Leta y’Uguhazwa kw’Itunga isaba neza ububiko bwo gusubirira amahinguriro ya gazi ariko araruhuka, ivyo bikaba bituma habaho ivyipfuzo vyemewe. Ubwa nyuma, ikirere giteye igomwe co muri California kigabanya igiciro co gucunga ubushuhe ugereranyije n’uturere dufise ubushuhe bukaze cane nka Arizona canke uturere dufise ubukonje bwinshi cane nk’ibiyaya vyo mu buraruko.
Iciyumviro nyamukuru: Ikorabuhanga Rikora, Rigenda Ritera imbere Ningoga
Ubuhinga bwo kubika inguvu za bateri bwahindutse buva ku buhinga bushasha buja ku bikorwa remezo vy’uruja n’uruza vyemewe. Ivy’ishimikiro birakora: ibikorwa vy’ubuhinga bw’umuyagankuba bihindura umuyagankuba ukaba inguvu zibitswe zifise ubushobozi bwa 85%, uburyo buteye imbere bwo kugenzura bukora neza ibihumbi vy’ingingo z’umubiri ata nkomanzi, kandi ugushiramwo uruja n’uruza rw’amashanyarazi bitanga ibikorwa bidashobora guhura n’ubuhinga busanzwe.
Igitigiri kiravyemeza. Ivyuma bikoreshwa kw’isi yose vyashitse hafi kuri 70 GW mu 2024 kandi bizoshika kuri 94 GW mu 2025-35% vy’iterambere. USA yonyene yongeyeko 10.4 GW mu 2024 kandi yiteze 19.6 GW mu 2025. Ivyo si ugushiraho 10.6 GW; ivyo ni ubuhinga bwo gukoresha burungikwa n’abakoresha uruja n’uruza ku musi ku musi.
Ivyiyumviro bitatu birahambaye cane: Ubwa mbere, ububiko bwa bateri burashoboza inguvu zishobora gusubirwamwo ku rugero mu gutorera umuti ingorane y'uguhagarara-atari mu buryo butunganye, ariko bihagije. Ubwa kabiri, akarusho k’umuvuduko ku bijanye n’uruvyaro rusanzwe ni ay’ukuri kandi ni agaciro; igihe c’inyishu c’imilisegonda gihindura ugushikama kw’uruzitiro. Ica gatatu, ubutunzi burakora mu masoko menshi ubu, atari mu bintu bimwebimwe vyo muri kazoza.
Ivyo bikoresho bizotera imbere. LFP chemistry iriko iragenda irahenda kandi iramara igihe kirekire. Uburyo bw'igihe kirekire-buriko buraba bwiza mu vy'ubutunzi. Uburyo bwo gukingira buriko buramanura ibintu bitera ubushuhe ku bintu bidasanzwe. Urugero rw’uguhingura ni rwo rutuma ibiciro bigabanuka 5-8% ku mwaka.
Ariko igihe co gutera imbere caramaze gushika. Ububiko bwa bateri ntibukiri akazoza k'ibikorwa vy'uruzitiro-ni ubu. Ishirahamwe ryose rikoresha amashanyarazi muri Amerika ubu ryizigira ubuhinga bwa bateri mu bikorwa vya misi yose. Ikibazo ntikikiri uko ububiko bwa bateri bukora, ahubwo ni uko twoshobora kubukoresha bihagije ningoga.
Ku muntu wese yiyumvira ivyerekeye uguhinduka kw’inguvu, gutahura ubuhinga bwo kubika inguvu z’amabateri ntibikiri ikintu co guhitamwo. Izo nzira ziriko zirahindura imirongo y’amashanyarazi kw’isi yose, zigatuma habaho amashanyarazi ashobora gusubirwamwo, kandi zigaragaza ko inzira yo kuva ku bikoresho vy’amazuku ishoboka mu buryo bw’ubuhinga. Ivyina vy’ivyuma vyitwa litiyumu biri imbere mu ngingo ngenderwako amamiliyoni, mu buryo nyabwo, birafasha guha ububasha kazoza.
