Uburyo bwo kubika inguvu z’amabateri ku rugero runini burakora neza mu bice bitatu bihambaye: ubushobozi bw’umubiri, ubutunzi, n’umuvuduko wo gukoresha. Ivyo iyo nganda yerekanye biciye mu kugabanya ibiciro vyihuta-kugabanya 89% kuva mu 2010 gushika mu 2023-n’uguturika mu bunini bw’imigambi, aho ibikoresho vy’umuntu ku giti ciwe ubu bishika ku bushobozi bwa gigawatt nyinshi. Gukoresha kw’isi yose ubuhinga bwo kubika inguvu z’amabateri ku rugero runini vyarateye imbere 35% mu 2025 gusa, vyongeyeko ubushobozi bushasha bwa 94 GW.
Ivyemezo vy'Ugushobora Gukura: Ivyiyumviro Bitatu vy'Ugukura
Uburyo bwo kubika inguvu za bateri ku rugero runini ntiburiko burakura mu buryo bumwe gusa-buriko buragwira mu bice vyinshi icarimwe. Gutahura ivyo bisaba kuraba iterambere ry’ubushobozi bw’umubiri, ubutunzi bw’ibiciro, n’ubushobozi bwo gukora nk’ibintu bitandukanye ariko bifitaniye isano.
Ubushobozi bwo ku mubiri bwarateye imbere cane. Haciye imyaka cumi, umugambi wo gukora amabateri y’amashanyarazi 40 MW wari ubonwa ko ari munini. Ubu, BYD iriko irakoresha ubuhinga bw’amashanyarazi 12,5 GWh mu bibanza bitanu muri Arabiya Saudite, mu gihe ikigo ca Edwards & Sanborn muri California gikoresha amashanyarazi 3.287 MWh y’ububiko bufatanijwe n’amashanyarazi 875 MW y’izuba. Ivyo si ibigereranyo vy'igerageza-ni ibikorwa vy'ubudandaji bitanga ibikorwa vy'uruja n'uruza buri musi.
Leta Zunze Ubumwe za Amerika zongeyeko ubushobozi bwo kubika amabateri 10,4 GW mu mwaka w’2024, ivyo bikaba vyerekana ko hariho ukwiyongera kw’ibice 66% ugereranije n’umwaka uheze. Ikindi gihambaye, abahinguzi bafise 19.6 GW bateguye mu 2025, bikaba vyerekana ko bokwihutisha aho kuba mu misozi. California yonyene ikoresha ubushobozi burenga 12,5 GW, mu gihe Texas ikurikira n’ubushobozi bwa 8 GW. Ivyo vyiyumviro vyerekana ko ububiko bw’amabateri ku rugero rw’uruzitiro-bwarengeye porogarama z’igerageza buja mu bikorwa remezo nyamukuru.
Ubutunzi bushobora gutera imbere buravuga inkuru iryoshe cane. Ibiciro vya bateri ya litiyumu -ion vyagabanutse cane kuva ku madolari nka 1.200 ku kilowatt{4}}isaha mu 2010 bishika hagati y’amadolari 137 na 150 ku kWh mu 2023-ivyo bikaba ari ugugabanya 89%. Ivyo bikurikira uburyo bumwe: ibiciro biragabanywa igice inyuma y’imyaka 4,1. Ivyiyumviro vyinshi vyerekana ko igiciro c’umugambi kizogwa munsi y’amadolari 100 ku kWh mu 2025, kikajabuka urugero rutuma ububiko bushobora guhangana n’ibikoresho vya kera vy’amashanyarazi ku bikorwa vyinshi.
Ukwo kugabanya ibiciro kuva ku bukungu bwa kera bw'urugero bukomezwa n'ubufatanye hagati y'inzego zitandukanye. Ihinduka ry’ibinyabiziga bikoresha umuyagankuba ryatumye habaho ishoramari rikomeye mu bushobozi bwo gukora litiyumu -kuva ku 242 GWh kw’isi yose mu 2020 gushika ku 822 GWh mu 2024, n’ibiharuro bizoshika ku 2.731 GWh mu mwaka w’2030. gutera imbere mu guhingura, kwungukira ku bushobozi bwo guhingura ntivyari ngombwa ko ivy’amahera ataco bimaze.
Uko ubutunzi bw'urugero butera iterambere ry'ububiko bwa bateri
Ihinduka ry’ubutunzi ry’ububiko bw’amabateri rigereranya kimwe mu bituma ubuhinga bw’inguvu bugabanya igiciro vyihuta cane. Hagati y’umwaka wa 2015 n’uwa 2018, ibiciro vy’amabateri y’ubuhinga bwa none vyagabanutse 70%. Kuva mu 2014 gushika mu 2024, igihe co kugabanya igiciro cari imyaka 4,1 gusa. Ku bijanye n’ivyo, izuba PV ryatwaye imyaka mirongo kugira ngo rishike ku kugabanya kw’ijanisha nk’ukwo.
Urugero rw'uguhingura nirwo rutwara uburyo bwa mbere bwo kugabanya ibiciro. Igihe ubuhinga bwa Amperex Technology (CATL), BYD, n’abandi bahinga bakuru bubaka amahinguriro maninimanini, barakwiragiza ibiciro bihoraho mu bipimo vyinshi vy’ibikorwa. Uruganda rukora 50 GWh ku mwaka rushika ku giciro ku -unite kidashoboka ku rugero rwa 5 GWh. Ivyo birakomera uko abahinguzi benshi bariko barahiganwa kw’isi yose, umwe wese agahiganwa kugira ngo ashike ku ntumbero nziza kuruta.
Uguhindura ubuhinga bwo gukoresha ubuhinga bwa litiyumu iron phosphate (LFP) bituma ibiciro bigabanywa vyihuta. Bateri za LFP zikuraho ivyuma bizimvye vyitwa cobalt na nickel, zigakoresha ivyuma vyinshi n’ivyuma vyitwa phosphate. Naho inguvu-zike gatoyi kuruta imiti ya nickel{3}}manganese-cobalt (NMC), ibiciro vy’ibikoresho vya LFP bike, ubuzima buramba bw’ingendo, n’ibiranga umutekano vyiza cane bituma iba nziza cane mu kubika ahagaze aho uburemere buhambaye kuruta mu modoka. Isoko rya LFP mu kubika inguvu ryaradutse kugira ngo ribe ari ryo riganza muri urwo rwego, abahinguzi b’Abashinwa bakoresheje ubuhinga bwabo muri iyo shimi.
Ibiciro vyo gushiramwo ibintu birenze amabateri na vyo nyene vyaragabanutse cane. Igiciro-c'-ibiciro vya sisitemu-harimwo ibikoresho vy'ubuhinga bwa none, ugushiramwo, n'ugushiraho-vyari hafi 60% vy'ibiciro vyose vya sisitemu mu gushirwaho kwa mbere. Gushiraho ibintu bimwe bimwe be n’uguhiganwa kwinshi ni vyo vyatumye ivyo bigabanuka. Ubwato bwa Tesla bwa Megapack burakoranijwe neza, bikagabanya ingorane zo kubishiramwo n’igihe co kubishiramwo. Igikoresho cose kibika amashanyarazi arenga 3,9 MWh kandi gishobora gushirwa mu ndwi aho gushirwa mu mezi.
Ariko rero, ugutera imbere mu vy’ubutunzi birashikirwa n’ingorane. Ibiciro vya litiyumu vyaradutse mu 2022 imbere y’uko bigabanuka cane gushika mu 2024, bituma habaho uguhinduka kw’ibiciro vy’ibikoresho. Bamwe mu basubira gukoresha ibintu vya kera bararwanye kubera ko ibiciro vya litiyumu vyagabanutse vyatumye ibikoresho vyasubiwemwo bidashobora guhangana n’ivyo bacukura mu gihe gito. Ivyiyumviro vyagutse vy’ibikoresho vy’amabateri-litiyumu, nikele, kobalti-bizana ukudakeka urugero rw’uguhingura rudashobora gukuraho.
Ugupima kw'umubiri: Kuva ku Megawatts gushika ku Gigawatts
Gushiramwo amabateri vyarakuze kuva ku mirongo y'ububiko bw'amazu gushika ku bikoresho vy'amashanyarazi vy'urugero rw'uruzitiro-. Ukwo gupima kw’umubiri kuba mu buryo bubiri butandukanye: ubunini bw’umugambi w’umuntu ku giti ciwe n’ubushobozi bwose hamwe.
Urugero rw’umugambi w’umuntu ku giti ciwe rwaragutse cane. Ico kibanza c’ububiko bw’inguvu ca Gambit muri Texas gikoresha amazu 81 atanga ubushobozi bwa 100 MW. Ishirahamwe ry’amashanyarazi ryitwa Homer muri Alaska ritanga amashanyarazi 46 MW. Ivyo bigereranya ibikorwa vy’ubudandaji bimenyerewe, si imigambi idasanzwe. Igikoresho kinini kuruta ibindi vyose gikora ahantu hamwe, Edwards & Sanborn muri California, gifatanya 3.287 MWh z’ububiko bw’amabateri n’izuba, ritanga ubushobozi bukomeye bwongerera ubushobozi bw’izuba buhinduka.
Imigambi y’ubwubatsi iriko irasunika imbibe. Umugambi wa Grenergy wo gukora Oasis de Atacama muri Shili uzotanga ubushobozi bwo kubika 11 GWh iyo uzoba wararangiye. Ivyo Sungrow izokoresha mu bibanza bitatu vyo muri Arabiya Saudite bizoba bifise amashanyarazi 7,8 GWh. Mu Budagi, ADS-TEC Energy yatangaje imigambi yo gushinga uruganda rwa 2 GWh-mu ruganda runini rw’i Buraya-rwitezwe ko ruzozana amafaranga angana na miliyoni 230 z’amayero ku mwaka biciye mu gucungera inguvu n’ibikorwa vy’uruja n’uruza.
Abategura umugambi bashika ku rugero biciye mu guhingura ibice. Uburyo bwa bateri bugizwe n'ibikoresho vyo gutwara-ibikoresho-bishobora gukoreshwa umwe umwe canke mu migwi myinshi. Gushiramwo 1 GW bisaba gusa ibikoresho vyinshi, si ubuhinga butandukanye cane. Ubwo buryo bushobora gutuma imigambi itangura ari mitoyi igakura uko amafaranga n’ivyo umuntu asaba bivyemerera, bikagabanya ingorane zo mu ntango.
Ukwibanda ku karere birerekana ukuntu ibikorwa remezo bivana. Texas ni yo irongoye ubushobozi bwa bateri butegekanijwe n’amashanyarazi agera kuri 60 GW mu gutegura, arengeye cane umuyoboro wa California w’amashanyarazi 35 GW. Ivyo vyerekana isoko ry’inguvu ryo muri Texas ritagira amategeko, ubutunzi bwinshi bushobora gusubirwamwo, n’ubwubatsi bw’uruzitiro buhemba ububiko bwihuta-. Arizona, Nevada, na Oregon na vyo nyene birakira ubushobozi buhambaye butegekanijwe, bikorana aho ubutunzi bw’izuba bukomeye cane kandi ibiciro vy’amashanyarazi vyerekana uguhinduka kwinshi ku musi.
Yamara rero, ugupima kw’umubiri guhura n’intambamyi nyazo. Gushiramwo amabateri manini manini hafi y’ibibanza vy’ugushiramwo ibintu mu bisagara birahura n’ingorane zo kuronka ubutaka no gutanga uruhusha. Imirongo y'uguhuza uruzitiro irema ibibazo-imigambi myinshi itegekanijwe irindira imyaka kugira ngo yemererwe guhuzwa. Ibikorwa remezo vy’ugutanga amakuru vyubatswe kugira ngo haboneke ibisigazwa vy’ibintu vya kera ntivyama bishobora kwakira neza ububiko busanzwe. Abahinguzi bavuga yuko rimwe na rimwe guhindura uruzitiro bisabwa bituma imigambi idashobora gukoreshwa mu vy’ubutunzi, mbere n’igihe ubuhinga bwa bateri ubwabwo bushobora guhera.
Igihe n’Isohoka: Ingorane yo Gupima Isigaye
Ivyuma vyinshi vy'amabateri y'urugero-bitanga amasaha 2 gushika kuri 4 yo gusohoka ku bushobozi bwavyo. Ubuhinga bwa 200 MW bufise ububiko bwa 800 MWh bushobora gutanga 200 MW mu masaha ane imbere y’uko buhera. Ico kiranga gihingura uruhara rw’ububiko mu rutonde kandi kigereranya urugero aho ugupima guhura n’intambamyi zikomeye cane z’ubuhinga.
Igihe c'amasaha ane-kibereye neza ibikorwa vyinshi vy'uruzitiro. Bateri ziruta izindi mu "gushavura kw'isonga"-kubika inguvu z'izuba zidahenda mw'ijoro canke mu gicugu no gusohora mu gihe c'isonga ry'ibisabwa ku mugoroba. Bitanga amategeko agenga incuro mu milisegonda, bikaba vyihuta cane kuruta amaturbine y’amazi. Batanga ubushobozi bwo gutangura umwirabura bwo gusubizaho uruzitiro. Izo nsiguro zizana amafaranga menshi cane hakoreshejwe ubuhinga busanzwe buhari.
Ariko rero, ububiko bw'igihe kirekire- buracari urugamba. Ababuranira inguvu zishobora gusubirwamwo biyumvira ko amabateri azosubirira amahinguriro y’inguvu akoreshwa n’ibisigazwa, agatanga ubufasha bw’iminsi myinshi mu gihe umuyaga n’izuba bihagaze. Ubutunzi bw'ubu bwa litiyumu-ion ntibushigikira iki kibazo c'ikoreshwa. Isaha yose yongereweko yo kubika isaba amabateri menshi, ivyo bikaba bituma ibiciro vyiyongera. Uburyo bw’amasaha 8 bugura nk’incuro zibiri ubw’amasaha 4 bufise ubushobozi bumwe, ariko buzana inyungu muri ubwo bushobozi bwongerekanye rimwe na rimwe gusa.
Igihe kirekire-ububiko bw'inguvu (LDES) busaba ubuhinga butandukanye. Bateri z’amazi zitwa vanadium redox flow zibika inguvu mu mazi y’amazi mu bidengeri vyo hanze, ubushobozi bwo gutandukanya n’ubushobozi bw’inguvu. Bateri y’amashanyarazi ya Rongke Power 175 MW/700 MWh mu Bushinwa, izotangura gukora mu mpera z’umwaka w’2024, iserukira uburyo bunini bwo kubika amabateri atari -litiyumu. Igihe c'amabateri y'amazi gishobora guhindurwa kigatuma ashobora kubika neza, naho nyene uburemere bwayo buke bw'inguvu n'ibiciro vyinshi vy'imbere bigabanya igihe co gukoreshwa.
Ivy’ubuhinga bwa shimi bishasha bishimikiye ku ntambamyi y’igihe. Ivyuma-amabateri y'umuyaga asezerana ibiciro bito cane ku kubika imisi myinshi-hakoreshejwe ibikoresho vyinshi, naho nyene aguma mu ntambwe z'igerageza. Bateri za sodium-ion zitanga ubundi buryo buzimvye kuruta lithium{6}}ion zikora nk’izo, naho nyene umunezero w’abahinguzi wakonjeye uko ibiciro vya LFP bibandanya kugabanuka. Bateri zikomeye-zishobora gutuma zitanga inguvu nyinshi, ariko ukuntu zikora zigoye bituma ziguma zizimvye.
Igihe c'intambamyi gihingura imiterere y'isoko. Ubushakashatsi bugaragaza ko amabarabara afise ubushobozi bwo gusubira guhinduka buri munsi ya 40% akeneye gusa ububiko bw'igihe gito-. Ku 80% vy'ibisubirwamwo, ububiko bw'igihe giciye -buca buba ngombwa. Inyuma ya 90%, ububiko bw'igihe kirekire-bugaragara ko ari ngombwa cane. Ivyuma vyinshi biguma munsi cane y'ivyo bipimo, bisobanura ko ubuhinga bw'amasaha 2-4 bukora neza mu gihe ubuhinga bumara igihe kirekire bugenda burakura.
Umutekano ku rugero: Gucungera ingorane zo guhunga kw'ubushuhe
Umutekano wa bateri ugereranya ingorane idafise -igiciro ishobora gutuma habaho uburyo bwo kubika inguvu za bateri ku rugero runini. Ivyuma bininibinini vy’ivyuma vyitwa litium{3}}ion bishiramwo inguvu nyinshi cane mu bibanza bigoye, kandi ukunanirwa birashobora gutera ingorane nyinshi. Ivyabaye muri Arizona, Beijing na Koreya y’Epfo vyatumye abantu benshi bapfa, kandi vyatumye amajana y’ibikoresho vy’ubuhinga bwa none bihagarara by’igihe gito.
Ivyiza vy’uko igice kimwekimwe cose ca bateri gishobora gusenyuka iyo gikora mu buryo busanzwe ni nk’ikimwe mu miliyoni cumi. Ariko rero, uguhunga kw’ubushuhe mu ngingo imwe birashobora gutuma ingingo ziri hafi zikora nabi mu gihe c’ugusenyuka. Kubera ko hariho amamiliyoni y’utugingo ngengabuzima turi mu gikoresho kinini, muri rusangi ubushobozi bwo kunanirwa kw’urutonde buraba buhambaye cane. Koreya y’Epfo yarashikiwe n’umuriro 28 wo kubika inguvu hagati ya 2017 na 2019, bituma abajejwe gucungera inguvu bafunga ibikorwa 522-35% vy’imirongo yose irindiriye itohoza.
Abahinguzi b’amabateri n’abayakoresha baravyishuje n’ibintu vyinshi vyo kwirinda. Uburyo bwo muri iki gihe bukoresha uburyo buteye imbere bwo gucunga amabateri bugenzura umuriro, umuriro, n’ubushuhe bw’ingingo imwe imwe mu gihe nyaco-, bugatandukanya ingingo zifise ingorane imbere y’uko ukunanirwa gukwiragira. Intambamyi z’umubiri hagati y’ibice vy’amabateri zirimwo umuriro ushobora gutera. Uburyo buteye imbere bwo kuzimya umuriro-kenshi bukoresha imyuka idakora aho gukoresha amazi-bukora ubwabwo iyo ibimenyetso vy’ubushuhe bibonye ko hariho ubushuhe butari bwo.
Ihinduka ry’ubuhinga bwa shimi bwa LFP rituma umuntu agira umutekano mwiza. Bateri za LFP zigaragaza ubushuhe bukomeye cane kuruta ubundi buryo bushingiye kuri nickel-, bituma ubushuhe buhunga buke kandi bukaba bukomeye cane iyo bushitse. Intambamyi y'uburemere buke bw'inguvu za LFP ntaco imaze ku bubiko buhagaze, bikaba biyigira ubuhinga buhambaye mu migambi mishasha y'ubuhinga-.
Ugutera imbere kw’amategeko kwerekana ubumenyi bugenda burakura mu bijanye n’ibikorwa. Amategeko y’umuriro ararushiriza gusobanura ibisabwa vyo gutandukanya umuriro, ingingo mfatirwako z’uburyo bwo guhagarika umuriro, n’ubushobozi bwo kugenzura ugushiraho amabateri. Intara zifise ububiko bwinshi, harimwo California na Texas, zateguye amategeko y’umutekano ashingiye ku matohoza y’ibintu bishobora gushika be n’inyigisho z’ubuhinga. Amasoko y’ubwishingizi yarakuze, n’abahinga mu vy’ubwishingizi barategura uburyo bwo kubika amabateri bushobora gutuma amafaranga y’ubwishingizi ashobora guhiganwa ku buryo buteguwe neza.
Yamara rero, ivyerekeye umutekano biragabanya neza uburemere bw’abakozi mu bice vy’abantu benshi. Ububiko bw’amasaha ya gigawatt-busaba uturere dukomeye two gukingira tuva mu mihana y’uburaro n’ibikorwa remezo bihambaye. Ico gisabwa c’ahantu kirahushanye n’ivyo uruzitiro rukeneye kugira ngo habeho ububiko hafi y’ibibanza vy’imizigo vyo mu bisagara. Hariho ahantu heza cane uhereye ku bijanye n’uruzitiro rwerekana ko ataco bimaze uhereye ku bijanye n’umutekano n’aho umuntu ahagaze.
Uruhererekane rw'ibikoresho n'ukuboneka kw'ibikoresho
Gupima uburyo bwo kubika inguvu z’amabateri ku rugero rwa terawatt-amasaha bigerageza uruhererekane rw’ugutanga amabuye y’agaciro kw’isi yose. Litiyumu, nikele, kobalti na manganese birahanganye n’iterambere ry’ivyo bisabwa biva ku modoka zikoresha umuyagankuba be n’ububiko buhagaze. Naho ububiko bwose busa n’ubuhagije ku bijanye n’ivyo umuntu akeneye, ubushobozi bwo gucukura amabuye y’agaciro, ubushobozi bwo gutunganya amabuye y’agaciro, n’ugushira hamwe kw’ivy’ubutaka birashobora gutuma habaho ingorane.
Ivyo gutanga litiyumu vyarateye imbere cane ariko vyarashikiwe n’ingorane z’igihe gito. Imigambi mishasha yo gucukura amabuye y’agaciro muri Ostraliya, Shili na Argentine yaratumye habaho ubushobozi bwongerekanye ku rubuga, mu gihe ubuhinga bwo gucukura litiyumu butaziguye busezerana gufungura ibibanza vy’amazi y’umunyu vyari bitagira ubutunzi mbere. Abahinga mu vy’imbere y’igihe baraharira nimba ugutanga bizotuma ivyo umuntu asaba bigenda neza canke biciye mu nzinguzingu z’ubukene n’ugusenyuka. Ibiciro bihinduka vyerekana uku kudakeka-ibiciro vya litiyumu carbonate vyadutse hejuru y'amadolari 80.000 kuri toni mu 2022 imbere y'uko bigwa munsi y'amadolari 15.000 mu mpera za 2024.
Cobalt iratanga ivyiyumviro bikomeye kuruta. Repubulika iharanira demokarasi ya Kongo ni yo itanga hafi 70% vy’ibikorwa vy’isi yose, ivyo bikaba bivyura ibibazo ku bijanye n’umutekano w’ibikorwa be n’ugutora ibikoresho bishingiye ku nyifato runtu. Abahinguzi b’amabateri baravyishuje mu kugabanya ibirimwo cobalt mu bikoresho vy’ubuhinga bwa cathode no guhindukira baja ku LFP idafise cobalt-. Bateri za NMC zahora zirimwo 20% vya cobalt ubu zikoresha 5% canke n’ibindi. Ukwiyongera kwa LFP kurakuraho neza cobalt mu bikorwa vyinshi vyo kubika.
Ubushinwa buraganza uruhererekane rwo gutanga amabateri uretse ibikoresho vya mbere. Amashirahamwe y’Abashinwa ni yo agenzura 70-80% vy’ubushobozi bwo gukora amabateri kw’isi yose, 80% vy’ubushobozi bwo gukora ama cathode, na 95% vy’ubushobozi bwo gukora ama anode. Ivyuma vy’ubuhinga bwa none vyitwa Amperex Technology (CATL), BYD, EVE Energy, na CALB vyubatse ibibanza vyinshi vy’ubuhinga bishika ku biciro ibindi bice bigorwa no kubishikana. Ukwo kwibanda ku bintu bituma ibihugu birondera inganda zikora amabateri mu gihugu bigira ingorane.
Intwaro z’Uburengero zarishuye zikoresheje politike y’inganda. Itegeko ry’Amerika ryo kugabanya inflation ririmwo amadolari 369 miliyaridi y’inguvu zisukuye, hakaba n’infashanyo nyinshi ku bijanye n’uguhingura amabateri yo mu gihugu. Ingamba z’Ubumwe bw’Uburayi na zo nyene zigamije kwubaka ubushobozi bwo mu karere. Ariko rero, gufata Ubushinwa bufise imyaka cumi-y’imbere bisaba ishoramari riramvye n’iterambere ry’ubuhinga. Amahinguriro mashasha afata imyaka kugira ngo yubakwe kandi afata igihe kirekire kugira ngo ashike ku mwimbu n’ibiciro bihuye n’ibindi.
Gusubira gukoresha ibikoresho vyoshobora amaherezo kugabanya ingorane zo kuronka ibikoresho vy’intango. Mu mwaka w’2035, nk’uko bivugwa n’Ishirahamwe Mpuzamakungu ry’Inguvu, amabateri y’ibinyabiziga bikoreshwa n’umuyagankuba azoba ari yo akoreshwa cane, ivyo bikaba bishobora kugabanya ivyipfuzo vya litiyumu, nickel, na cobalt ku rugero rwa 25%, 25%, na 40% mu mwaka w’2050. gusubira gukoresha ibikorwa remezo kugira ngo bihure n’ibihe vy’ikiruhuko c’izabukuru vy’amabateri birafise ingorane zavyo bwite.
Ingorane yo gusubira gukoresha: Gufunga uruzitiro ku rugero
Gusubira gukoresha amabateri bigereranya urugero rw’ubuzima buramba aho ugupima biguma inyuma cane y’ugukoresha. Naho ubushobozi bwo gushiramwo ibintu bukura 30-40% ku mwaka, ibikorwa remezo vyo gusubira gukoresha ibintu bishasha biratera imbere buhoro cane, bikaba bituma habaho ukudahuza gukomeye uko gushiramwo ibintu vya kera bishika ku mpera y’ubuzima.
Igitigiri c’ibintu bisubira gukoreshwa muri iki gihe kivuga inkuru iteye ubwoba. Mu bice bitari munsi ya 5% vy’amabateri ya litiyumu-ion asubirwamwo muri Leta Zunze Ubumwe za Amerika no mu Bumwe bw’Uburaya, Australiya ikaba icungera 2-3% gusa. Ivyo si ingorane z'ubuhinga-amabateri ashobora gusubirwamwo-ariko ni ingorane y'ubutunzi n'ivy'ubuhinga. Ivyuma vy’ugukorakoranya ibintu biracari bitaratera imbere, ibiciro vyo gutunganya ibintu birarenga agaciro k’ugusubirana ibintu ku bici- ro vy’ibicuruzwa biriho ubu, kandi imiterere itandukanye y’amabateri iragora gusenyura ibintu vy’ubuhinga bwa none.
Hariho inzira zitatu nyamukuru zo gusubira gukoresha ibintu, imwe yose ikaba ifise ubutunzi n’ibidukikije bitandukanye. Pyrometallurgy ni ugufukura amabateri ku bushuhe bwinshi kugira ngo umuntu abone ivyuma, ariko akabura litiyumu na graphite mu gihe akoresha inguvu nyinshi. Hydrometallurgy ikoresha uburyo bw’imiti kugira ngo ikuremwo ibikoresho mu buryo bubereye, igashika ku rugero rwo hejuru rwo gusubirana ariko igatuma habaho imigende y’imyanda y’imiti. Gusubira gukoresha ibintu bishaje bisanura no gusubira gukora ibikoresho vya katode bitabivunitse, bikaba bishobora gutanga ubutunzi bwiza n’ingaruka mbi ku bidukikije, ariko bisaba gutoranya amabateri hakurikijwe ubuhinga bwa shimi kandi biguma ahanini ku rugero rwa laboratwari.
Ishirahamwe ryinshi ry’ugusubira gukoresha ibintu vya kera ryaronse amamiliyaridi y’amahera y’ubudandaji ashingiye ku masezerano y’ugutera imbere, ariko 2024 yarazanye intsinzi. Igiciro ca litiyumu na nickel cagabanutse catumye ibikoresho vyasubiwemwo bidashobora guhangana n’ivyo bicukurwa mu gihe gito, bica bihungabana uburyo bwo gukora ubudandaji bwari bushingiye ku kugurisha ibikoresho vyasubiwemwo. Aqua Metals yarahuye n’ingorane z’amahera igihe ibiciro vya litiyumu vyagabanuka mu gihe c’itohoza ry’ivy’ubudandaji. SK Ecoplant yagurishije umugabane wayo muri Ascend Elements, yongera kwibanda kure y’ugusubira gukoresha amabateri.
Yamara rero, abasubira gukoresha ibintu bamwebamwe barashitse ku rugero rufise insiguro. Redwood Materials, yashinzwe n’uwahoze ari umuyobozi mukuru wa Tesla JB Straubel, ikora amabateri 20 GWh ku mwaka-amatoni 60.000 y’ibikoresho. Iyo sosiyete yaronse amadolari hafi miliyoni 200 mu mwaka w’2024 mu kugurisha umuringa, aluminium n’ibikoresho vy’amabateri vyagaruwe. Ivyo vyerekana ko abakoresha ibintu bishasha bafise amahera menshi bafise ubuhinga bwo gukora ubucuruzi buhurikiyemwo bashobora gukora neza no mu gihe igiciro c’ibicuruzwa gihinduka.
Inzego z’amategeko ziriko ziratera imbere kugira ngo zitegeke gusubira gukoresha ibintu. Amategeko y'Ubumwe bw'Uburayi yerekeye amabateri asaba ko habaho ibintu bikeyi bishobora gusubirwamwo mu mabateri mashasha n'intumbero zo gukusanya amabateri y'iherezo-y'ubuzima bw'-. California n’izindi leta za Amerika ziriko zirategura amategeko y’inshingano z’abahinguzi zituma abahinguzi b’amabateri babazwa ivy’amahera ku bijanye n’ugucungera iherezo ry’ubuzima. Aya mabwirizwa akwiye gutuma habaho ishoramari ry’ibikorwa remezo vyo gusubira gukoresha ibintu bishaje, naho nyene ubushobozi bwayo buvana n’ugushirwa mu ngiro n’uguhuza ibikorwa mpuzamakungu.
Ingorane yo gusubira gukoresha ibintu irakomera uko urugero rugenda rurakura. Mu mwaka w’2030, amabateri agera kuri 318 GWh azoshika ku mpera y’ubuzima bw’amabateri, hafi igice c’amabateri akoreshwa n’umuyagankuba. Ivyuma vy’ububiko bihagaze kuva mu ntango z’imyaka ya 2020 bizotangura guhagarika mu myaka ya 2030, bizokwongera kuri uwo mugezi. Ubushobozi bwo gusubira gukoresha ibintu bishasha butegerezwa kwongerekana incuro nka 50 mu myaka cumi izoza kugira ngo bishobore gukora ibiharuro vy’ibintu bitegekanijwe, ivyo bikaba bisaba ko hashirwamwo amahera atagira uko angana mu nzira zo gukorakoranya ibintu, mu bibanza vyo gutoranya ibintu no mu bibanza vyo gutunganya ibintu.
Ugushiramwo uruzitiro: Intambamyi zo gukuraho ibikorwa remezo
Ububiko bwa bateri ntibugira urugero mu kwitandukanya-butegerezwa gukorana n'ibikorwa remezo vy'uruzitiro biriho vyateguwe hirya no hino y'uruvyaro rwo hagati. Ukwo gukorana birazana ingorane zitandukanye n’uguhingura canke gushiramwo ibikoresho vy’umuntu ku giti ciwe.
Imirongo y'uguhuza uruzitiro yacitse ikibazo gikomeye. Muri Leta Zunze Ubumwe za Amerika, ububiko bw’amabateri burenga 600 GW bwicaye mu mirongo y’uguhuza butegereje kwemererwa n’ishirahamwe ry’amazi kugira ngo buhuzwe. Ivyo gusubiramwo kenshi bifata imyaka 3-5, muri iyo myaka ubutunzi bw’umugambi burashobora gusenyuka uko ibiciro bihinduka n’amahirwe yo kwinjira ahinduka. Imigambi myinshi irava ku mirongo inyuma y’aho inyigisho zigaragaje ko bisabwa guhindura ubuhinga bwo gutanga amakuru bituma idashobora gukoresha ubutunzi.
Ibikorwa remezo vyo gutanga amakuru bigabanya aho ububiko bushobora gukoreshwa neza. Kwongera ubushobozi bwa bateri mu bice bifise ingorane zo gutanga amakuru birashobora kwongera umuvuduko mu kwongera umuzigo wo gushaja. Hari imigambi ibonwa ko itanga umuhango mu bijanye n’aho ikora, irananirwa kubera ko ibikorwa remezo vy’uruja n’uruza vyo mu karere bidashobora kuyifasha ata vyo guhindura bizimvye bigwa ku wuwukora. Ivyo bituma habaho catch-22: ububiko bwoshobora gukuraho ingorane zo gutanga amakuru, ariko ntibushobora kwubakwa aho bukenewe cane kubera izo ngorane nyene.
Imiterere y’isoko mu turere tumwetumwe ntiyahuye n’ibiranga ububiko. Bateri zikoresha kandi zigatanga umuyagankuba icarimwe, ntizijanye n’ivyigwa vy’ugutanga umuyagankuba canke ivy’ugutwara umuyagankuba. Amategeko y’isoko ry’ubudandaji yanditswe ku mageneratore y’ibisigazwa vy’ibintu vya kera ashobora kudasubiza neza ububiko ku bikorwa vyose bitanga-ugutegeka incuro, gufasha umuriro, gukuraho umudugararo-birenze ugukemura inguvu kworoshe. Amategeko ya Komisiyo y’Igihugu ijejwe gucungera inguvu muri Leta Zunze Ubumwe za Amerika yaratumye amasoko agira ihinduka, ariko ukuntu ashirwa mu ngiro biratandukanye hakurikijwe uturere.
Ivyiyumviro vy’ububiko muri California na Texas bimwe bimwe vyerekana amasoko ahemba neza ububiko. California "duck curve"-ibara ry'umugoroba ry'agahomerabunwa-rikenewe uko izuba rizimangana-rirema ibimenyetso bikomeye vy'igiciro c'amasaha 4-yo kubika. Isoko ry’inguvu gusa ryo muri Texas rituma ububiko bushobora gufata ibiciro vyinshi cane mu bihe vy’ugutanga ingufu zikomeye, rimwe na rimwe bikarenga amadolari 1.000 ku MWh. Ibindi bice bifise uguhinduka guke kw’ibiciro canke imigambi yo kwishura ubushobozi yagenewe amageneratore ya kera bibona ko ububiko bugenda buhoro ataco buvuze mu buryo bw’ubuhinga.
Porogarama n’ubugenzuzi birazana ingorane n’amahirwe. Uko amabateri yinjira mu mubiri, gucunga ibihumbi vy’ibintu vy’ububiko bitangazwa bisaba uguhuza ibikorwa bikomeye. Abakoresha uruzitiro barakeneye kuboneka mu bubiko bw'ububiko-bw'-ibiciro, ukuboneka, n'ubushobozi bwo kohereza mu gihe nyaco-. Uburyo bwo gucunga amabateri butegerezwa kwishura ku bimenyetso vy'uruzitiro mu milisegonda kugira ngo bugenzure incuro mu gihe butera imbere mu gihe kirekire-inyungu mu migende myinshi y'agaciro. Amashirahamwe nka Tesla na Fluence yarateguye ubuhinga bwa SCADA n’ubuhinga bwo gutuma ibintu bigenda neza bifata amato y’ububiko nk’ibikoresho vy’amashanyarazi, ariko kubishira mu buryo bwo kugenzura ibikorwa vy’amashanyarazi bisaba gutegura ingingo mfatirwako n’uguhindura inzego.
Ivyigwa birabandanya
Ububiko bwa bateri buva ku gukomeza ibiharuro vy'inyigisho-urugero ibiciro bigabanukako uko ugukoresha kw'ibiharuro bigenda bikubita kabiri. Amakuru y’akahise yerekana ko amabateri ya litiyumu-ion ashobora kugabanya igiciro ku rugero rwa 20% iyo ubushobozi bushizweho bugwiye kabiri, bikaba bihuye canke birenze ibiharuro vy’inyigisho z’ubuhinga bukomeye nk’ubuhinga bw’izuba.
Hari ibintu vyinshi bishigikira kubandanya kwiga. Ivyo guhingura ibintu biracari n’aho vyotuma bigenda neza. Umusaruro w’uguhingura utugingo ngengabuzima uratera imbere uko amahinguriro aronka ubumenyi. Ivyuma bigabanya ibikorwa. Gukoresha ibikoresho birarushiriza kuba vyiza, bikagabanya imyanda. Ivyo bintu vy’iterambere vyiyongera birundanira mu kugabanya cane ibiciro mu gihe c’ingendo z’ugushirwaho.
Ugutera imbere kw'ubuhinga bwa shimi gutuma intambwe-ihinduka ry'iterambere. Ubuhinga bwa litiyumu-ion bugezweho ubu bugereranya imyaka mirongo y’ugutunganya, ariko ntibwarangije ubushobozi bwo gutera imbere. Anode zishingiye kuri silikoni-zishobora kwongera uburemere bw’inguvu n’ibice 20-30%, zigabanura igitigiri c’ingingo z’umubiri ku bushobozi bumwe bumwe. Ivyo bikoresho bikomeye bishobora gutuma haba amabateri akomeye kandi afise umutekano mwinshi, naho ingorane zo kuyahingura zatumye incuro nyinshi ashobora gucuruzwa. Ubuhinga bwo gupfuka ama electrode yumye, bwatangujwe na Maxwell Technologies ubu bukaba buriko burakoreshwa muri Tesla, bwoshobora kugabanya inguvu zo gukora n’ibiciro ku bice 10-15%.
Inyigisho z'imice itandukanye zirabandanya kugirira akamaro ububiko buhagaze. Iterambere ryose ry’amabateri y’imodoka zikoresha umuyagankuba-n’imodoka zikoresha umuyagankuba rikomeza gukura ku rugero rwa 30-40% ku mwaka-bihindura ububiko bwiza, buzimvye buhagaze n’amahera makeyi y’inyongera ku bijanye n’iterambere. Ubu bufatanye busa n’ubuzogumaho gushika mu myaka ya 2020 kuko EVs ziguma ari isoko rinini ry’inganda z’amabateri mu bwinshi n’ishoramari.
Ariko rero, igitigiri c’inyigisho kirashobora kugabanuka. Uko ubuhinga bugenda burakura, ivyo gutera imbere vyoroshe biraruha, ingorane zikomeye zigaca zigumaho. Ivyo vyashikiye Solar PV hagati mu myaka ya 2010, igihe ugugabanya ibiciro vyagabanutse inyuma y’imyaka myinshi y’ugugabanuka cane imbere y’uko urugero rw’uguhingura n’imiterere mishasha y’utugingo ngengabuzima bisubira gutera imbere. Ububiko bwa bateri bushobora guhura n’ibihe nk’ivyo, cane cane iyo habayeho ingorane z’ibikoresho vya mbere canke iyo inganda zihindukiye zija ku buhinga butandukanye cane busubira gutangura kwiga.
Isoko ryuzuye mu bikorwa bimwebimwe vyoshobora gutuma iterambere ry’ugukoresha rigenda buhoro. Igihe ibikoresho bishobora gusubirwamwo hamwe n’ububiko bizoba bishitse ku ntumbero nziza zo ku mugoroba mu masoko meza nka California na Texas, iterambere rishobora kuva ku gukuraho ubuhinga bwo gukoresha ibikoresho -ivyo bisaba cane bisaba ububiko bw’igihe kirekire ku giciro kitarashikwako. Intambamyi z’amategeko, ivyerekeye umutekano, canke ukurwanywa na bose vyoshobora gutuma ugushirwa mu turere tumwetumwe bigabanywa, bikagabanya amasoko no bikagabanya ubutunzi.
Impinduka mu karere mu kuroranirwa
Ububiko bwa bateri burangana mu masoko atandukanye, bugaragaza ingene politike, imiterere y’isoko, n’ugutanga ibikoresho bihingura uburyo bwo gukoresha. Gutahura izo mpinduka bitanga ubumenyi ku bijanye n’ibituma umuntu ashobora gutera imbere n’intambamyi.
Ubushinwa ni bwo burongoye gukoresha ububiko bw’amabateri kw’isi yose, bufise ibice birenga 55% vy’ubushobozi bwose. Ivyo vyerekana ikibanza Ubushinwa bufise nk’igihugu gikomeye kw’isi gikora inguvu zishobora gusubirwamwo, kandi kikaba ari co gikora cane amabateri. Intwaro z’intara zitegeka ko imigambi y’umuyaga n’izuba ibamwo ububiko-kenshi 10-20% vy’ubushobozi bwo gutanga umuriro n’amasaha 2-amara -kwihutisha gukoresha. Ariko rero, amahinduka aherutse gukorwa mu ngingo mfatirwako afise intumbero yo kuva ku bikorwa vy’ubutegetsi akaja ku buryo bushingiye ku masoko, bishobora gutuma iterambere ry’igihe gito rigenda buhoro mu gihe ubutunzi bw’imigambi bugenda buratera imbere uko igihe kigenda kirarenga.
Leta Zunze Ubumwe za Amerika zabonye iterambere ridasanzwe mu 2024, zongerako ubushobozi burenga 12 GW-burengeye incuro zibiri ubushobozi bwashizweho. Itegeko ryo kugabanya inflation ry’imisoro y’ishoramari ry’ububiko bwigenga, atari ububiko bw’izuba-plus- gusa, ryakuyeho intambamyi nini. California na Texas vyose hamwe bifise 70-80% vy’ubushobozi bwa Amerika, naho nyene hari izindi leta ziriko zirakura. Arizona, Nevada, na New York vyerekana ubushobozi buhambaye bwateguwe. Ubwo butandukanye bw’ibibanza buragabanya ukwizigira politike za Leta imwe kandi bugakwiragiza inyigisho zijanye n’urugero mu turere twose.
Uburayi burasigaye inyuma naho bufise intumbero zikomeye zo gusubiramwo. Ubudage, Ubuholandi n’Ubwongereza ni vyo birongoye ivy’ugutuma abasirikare bo mu Buraya, ariko ubushobozi muri rusangi buracari inyuma cane ya Amerika n’Ubushinwa. Ibiciro vy’amashanyarazi vyinshi n’uguhinduka kw’ibiciro ku musi ku musi bigabanya amahirwe yo gukemura ibibazo, naho amasoko y’ibikorwa vy’amashanyarazi atanga inyungu. "Green Deal" y'Ubumwe bw'Uburaya n'imigambi yo gukora amabateri bigamije kwihutisha gukoresha no kwubaka uruhererekane rw'ibikoresho vyo mu gihugu, naho nyene ukuroranirwa gutaramenyekana.
Amasoko ariko arakura aratanga amahirwe menshi yo gutera imbere afise ingorane zitandukanye. Ubuhinde, Aziya yo mu Bumanuko bushira Ubuseruko be n’ibice bimwebimwe vyo muri Amerika Latini na Afirika birafise amashanyarazi menshi cane, ubutunzi bwinshi bushobora gusubirwamwo, be n’imirongo y’amashanyarazi yoshobora kwungukira ku kubika. Ariko rero, ibiciro vy’amahera, ukudakeka kw’ingingo mfatirwako, n’imiterere y’isoko idateye imbere cane, biratuma ibikorwa bigenda buhoro. Ibihugu bimwebimwe ntibigira amasoko y’amashanyarazi y’ingero yose, ivyo bikaba bituma bidasobanuka neza ingene ububiko bwotuma umuntu aronka amahera. Ivy’iterambere mpuzamakungu n’ubufatanye bw’ubuhinga bwa none vyoshobora gufungura ayo masoko, ariko iterambere ryabaye buhoro buhoro.
Ivyo Uguhindura Inguvu Bisobanura
Ivyemezo vyerekana ko uburyo bwo kubika inguvu z’amabateri ku rugero runini bukora mu bipimo vyinshi bihambaye. Ubushobozi bw’umubiri bwavuye kuri megawatts buja kuri gigawatts mu bikoresho bimwe bimwe, imigambi minini cane ubu ikaba irenga 10 GWh. Ibiciro vyagabanutse 89% mu myaka 13 biciye mu rugero rw’uguhingura no kwiga-ku-gukora. Ikoreshwa kw'isi yose ryihuta ku rugero rwa 30-40% ku mwaka, n'amashanyarazi arenga 140 GW mu mirongo y'imigambi gushika mu 2030.
Yamara rero scalability si imwe canke nta n’aho igarukira. Igihe kiguma ari gito ku masaha 2-4 ku mirongo ya litiyumu-iyon, bikaba bigabanya uruhara mu nzira zifise ubushobozi bwo gusubira gukoreshwa cane. Ivyerekeye umutekano biragabanya neza uburemere bw'abakozi hafi y'abantu. Imirongo y’ugutanga ibikoresho irahura n’ingorane zishobora gushika, naho nyene uguhinduka kw’ubuhinga bwa shimi ku bikoresho vyinshi bigabanya ivyo. Ibikorwa remezo vyo gusubira gukoresha ibintu vya kera birasigaye inyuma cane mu gukoreshwa, bikaba bitera ivyiyumviro vy’ubuzima buramba. Ugushiramwo uruja n’uruza rw’amazi biragora imigambi igenda buhoro mbere n’aho amabateri ubwayo akora neza.
Ivyo bigoranye ntibikwiye gupfukiranya inkuru y’ishimikiro y’uguterimbere. Ububiko bwa bateri bwarateye imbere kuva ku bikorwa vy’agaciro gushika ku bikorwa remezo vy’uruja n’uruza mu myaka nka cumi. Imigambi yari kuba idashoboka canke idafise ubutunzi mu 2015 ni ibisanzwe mu 2025. Igitigiri c’inyigisho kigaragaza ko ibiciro bizobandanya kugabanuka, bigatuma ubutunzi bushobora gukoreshwa. Amashirahamwe menshi ubu akora ku rugero rw’amasaha ya gigawatt-yo gukora no gukoresha, afise uruhererekane rw’ugutanga ibikoresho, imigero yemejwe, n’imigenzo y’ibikorwa itahurwa.
Imyaka cumi izoza izogerageza nimba ugupima bizobandanya ku rugero ruriho ubu canke bizohura n’imipaka ikomeye kuruta. Intambamyi z’ivy’umubiri zirashobora gukomera. Ivyabaye mu bijanye n’umutekano vyoshobora gutuma habaho amategeko abuzanya. Ivyo gukoresha vyoroshe vyoshobora guhera, bikasigaza ibindi bikomeye. Gusubira gukoresha ibintu bishasha bitegerezwa gutera imbere cane canke bikazana ingorane ku bidukikije. Ivyuma vy'ububiko vy'igihe kirekire-bitegerezwa guseruka kugira ngo bishobore gusubirwamwo.
Izo ngorane zisa n’izishobora gutorwa aho kuba izo ngorane z’ishimikiro. Inganda zikora amabateri zaratsinze incuro nyinshi ivyo vyari vyaravuzwe ko zizotuma zigira ingorane, kuva ku kubura litiyumu gushika ku bijanye n’umutekano gushika ku bijanye n’ubutunzi. Ubushobozi bwo gukora ibintu burabandanya kwaguka. Ivyuma bishasha vy’ubuhinga bwa shimi birasohoka ubudasiba. Ubuhinga bwo gusubira gukoresha ibintu buratera imbere mbere n’igihe ubutunzi buriko burahinduka. Infashanyo y’amategeko irakomera kw’isi yose uko inyungu zigaragara.
Ububiko bwa bateri buraroranirwa cane ku bijanye n’imihindagurikire y’ikirere n’inguvu. Ivyo bikoresho bishobora gusubirwamwo nk’umuyaga n’izuba bitanga amashanyarazi mashasha atari menshi mu masoko menshi, ariko bikeneye ububiko kugira ngo bihe ubushobozi bukomeye. Idolari ryose rigabanutse mu biciro vyo kubika bituma ukwinjira kw’ibintu bishobora gusubirwamwo vyinshi bituma habaho ubutunzi. Gigawatt yose y’ububiko ikoreshwa yubaka icizigiro mu nzira zishobora gusubirwamwo-zihambaye. Ikibazo si uko ububiko bushobora gutera imbere-bufise -ariko ni ukuntu bwihuta kandi buzoshika kure gute, ivyo bizogena canecane urugero rw'uguhinduka kw'inguvu muri iki kinjana.
Ibibazo bikunze kwibazwa
Ni ubuhe buryo buhambaye bwo kubika amabateri bukora ubu?
Umugambi wa Edwards & Sanborn muri California ubu niwo ufise ubushobozi bwo gukora 3.287 MWh, ushizwe hamwe n’amashanyarazi 875 MW y’izuba. Ariko rero, mbere n’imigambi minini iriko irakorwa, harimwo n’umugambi wa BYD wo gukoresha 12,5 GWh mu bibanza bitanu muri Arabiya Saudite n’umugambi wa Grenergy wo gukoresha 11 GWh Oasis de Atacama muri Shili.

Ivyo bigereranya igihe co kugabanya igiciro c'imyaka nka 4,1, n'ibiharuro vyerekana ko igiciro kizogabanuka kikaja munsi y'amadolari 100 ku kWh mu 2025.
Ni kuki amabateri menshi akora amasaha 2-4 gusa?
Igihe co gukora kigaragaza ubutunzi aho kwerekana ko ubuhinga budashoboka. Isaha yose yongereweko yo kubika isaba amabateri menshi, ivyo bikaba bituma ibiciro vyiyongera. Amasaha ane-uburyo burabereye ibikorwa vyinshi vy'ubu-uguhindura isonga, gutegeka incuro-ku bukungu bukwegera. Igihe kirekire gisaba ubuhinga butandukanye nk’amabateri y’amazi canke uburyo bushasha bw’ishimikiro bukiriko buratera imbere.
Mbega umuriro wa bateri ni ingorane nini ku bubiko bwinshi-?
Umuriro wa bateri ugereranya ingorane zishobora gutunganirizwa ariko zitari -zito. Naho ubushobozi bwo gusenyuka kw’ingingo z’umubiri ku giti cabo ari buke cane (kimwe mu miliyoni cumi), ugusenyuka kw’ingingo ngenderwako bishobora gushika mu bibanza bininibinini. Inganda zarishuye zikoresheje uburyo bwiza bwo gucunga amabateri, gukingira ibintu, guzimya umuriro, no guhindukira zija ku buhinga bwa LFP butekanye kuruta. Inzego z’amategeko zarateye imbere zishingiye ku matohoza y’ibintu vyabaye, zishinga ingingo ngenderwako z’umutekano zigabanya cane ingorane.
Ni igiki kiba ku ma bateri iyo ashitse ku mpera-y'ubuzima bwa-?
Ubu, amabateri ya litiyumu-ion atari munsi ya 5% arasubirwamwo muri Amerika no mu Buraya. Hariho inzira nyinshi zo gusubira gukoresha ibintu -ivy’ivyuma vy’umuriro, ivy’amazi, n’ivy’ugusubira gukoresha ibintu bitaziguye-imwe yose ifise ingaruka zitandukanye ku bukungu no ku bidukikije. Ubushobozi bwo gusubira gukoresha ibintu butegerezwa gutera imbere cane mu myaka cumi izoza kugira ngo bishobore guhangana n’ibihe vy’ikiruhuko c’izabukuru vy’amabateri. Inzego z’amategeko zirushiriza gutegeka gusubira gukoresha ibintu no gushinga intego z’ibintu vyasubiwemwo mu mabati mashasha.
Mbega ububiko bwa bateri bwoba bushobora gusubirira burundu amahinguriro y’amashanyarazi akoresha amakara y’ibisigazwa?
Ububiko bw'amabateri burashobora gusubirira amahinguriro "peaker" y'amavuta y'ibisigazwa akora mu gihe c'isonga ry'abasaba, kandi vy'ukuri birasanzwe biriko birabikora mu masoko menshi. Ariko rero, gusubirira ivyatsi vy’ibisigazwa vy’ibintu vya kera bisaba igihe kirekire-bika (imisi aho kuba amasaha) ku giciro kitarashikwako. Ivyuma bifise ibihinduka bihinduka biri munsi ya 40% bikeneye gusa ububiko bw'igihe gito-. Inyuma y’ibice 80-90% vy’ibintu bishobora gusubirwamwo, ububiko bw’igihe kirekire buraba ikintu gihambaye, bisaba ubuhinga bukiri mu gutegurwa canke bugurishwa hakiri kare.
