Nansi into engase ikumangaze: ubuchwepheshe bamandla ahlanzekile obukhula ngokushesha-akuwona amaphaneli elanga noma izinjini zomoya. Kuyinto abantu abaningi abangakaze bezwe ngayo, ifihlwe ezindlini zokugcina izimpahla nasezitsheni kuwo wonke amagridi kagesi emhlabeni wonke. I-BESS - Isistimu Yesitoreji Samandla Ebhethri - iyinjini engabonakali eyenza amandla avuselelekayo asebenze esikalini.
Isifinyezo sizwakala njengobuchwepheshe. Boring, ngisho. Kepha ngemuva kwalezo zinhlamvu ezine kuhlezi imakethe yomhlaba wonke engama-dollar ayizigidi eziyizinkulungwane ezingama-50 ekhula ngo-25% ngonyaka, ubuchwepheshe obuvimbe ukucisha ugesi okukhulu ngoFebhuwari 2024 eTexas, kanye nocezu olungekho olugcina lwenza amandla avuselelekayo angama-24/7 asebenze. Uma ubuza ukuthi "imelelani i-BESS," ubuza ngempela ngobuchwepheshe obubhala kabusha buthule imithetho yokuthi ugesi usebenza kanjani.
I-BESS Evolution Cascade: Ukusuka ku-Acronym kuya kuGridi Revolution
Izindatshana eziningi zizokutshela ukuthi i-BESS imele "Isistimu Yesitoreji Samandla Ebhethri." Kulungile ngokobuchwepheshe. Kodwa lokho kufana nokuthi u-Tesla wenza "izimoto" - zibe yiqiniso, kodwa uphuthelwa ukuguqulwa okwenzeka ngaphansi.
Nansi indlela yokuqonda ngempela i-BESS ngalokho engikubiza nge-Evolution Cascade:
Izinga 1: Isifinyezo→ BESS=Uhlelo Lwesitoreji Samandla Ebhethri
Izinga 2: Ubuchwepheshe→ Amabhethri ashajwa kabusha + amandla kagesi + amasistimu okulawula
Izinga lesi-3: Uhlelo→ Isixazululo esihlanganisiwe esigcina ugesi futhi siwudedele lapho kudingeka
Izinga lesi-4: Umgogodla Wegridi→ Ingqalasizinda evumela amandla avuselelekayo ukuthi aqhudelane nezinto zokubasa ezimbiwa phansi
Izinga lesi-5: Isinikezeli Sekusasa→ Isisekelo sayo yonke into kagesi - kusukela ezimotweni kuya kuwo wonke amadolobha
Izinga ngalinye lakhela kwedlule. Ukuqonda le midlalo kuchaza ukuthi kungani i-BESS isuka kubuchwepheshe be-niche yaya kungqalasizinda yamasu esikhathini esingaphansi kweminyaka eyishumi.
Ukuhlukanisa I-B-E-S-S: Ukuthi Uhlamvu Ngalunye Lwangempela Lusho Ukuthini
Ake sikuhlukanise kahle lokhu, ngoba imininingwane ibalulekile.
I-B eyebhethri (Kodwa Ayifani Nefoni Yakho)
Uma abantu abaningi bezwa "ibhethri," bacabanga ukuthi amabhethri e-AA noma amashaja efoni. Igridi-isikali se-BESS sisebenza endaweni ehluke ngokuphelele. Insiza eyodwa-ukufakwa kwe-BESS kwesikali kungagcina amandla angu-1,000 megawatt-amahora (MWh) - anele ukunika amandla amakhaya angu-750,000 ihora. Isikhungo i-Moss Landing eCalifornia sigcina i-3,000 MWh ezigabeni ezimbili, okuyenza ibe indawo yokufakwa kwamabhethri enkulu kunazo zonke emhlabeni ngaphambi kokuba idliwe amaphrojekthi amasha aseShayina ngo-2025.
Lawa akuwona amabhethri omthengi akhulisiwe. Ikhemistri iyahluka (ikakhulukazi i-lithium iron phosphate manje kune-nickel-i-manganese{2}}i-cobalt kukhompyutha yakho ephathekayo), amasistimu okupholisa ayizinga lezimboni{3}}, futhi izimiso zokuphepha ziphikisana nezindawo zenuzi. Ngokusho kokuhlaziywa kwe-EPRI kwango-2024, ukwehluleka okungu-72% kwe-BESS kwenzeka phakathi neminyaka emibili yokuqala - hhayi ngenxa yokuthi ubuchwepheshe abuthembeki, kodwa ngenxa yokuthi ukuhlanganiswa nokusetshenziswa kuyimisebenzi eyinkimbinkimbi edinga ukunemba.
I-E ingeyamandla (Uhlobo Olugciniwe)
Ukugcinwa kwamandla kuzwakala kulula uze umbe ku-physics. I-BESS ayimane nje "ibambe" ugesi njengamanzi ebhakedeni. Iguqula amandla kagesi abe amandla amakhemikhali, iwagcine, bese iwabuyisela emuva lapho kudingeka. Umjikelezo ngamunye wokuguqula ulahlekelwa u-10-15% wokushisa nokumelana - nenkinga "yohambo oluya nokubuya" yonke ubuchwepheshe bokulondoloza ebhekene nayo.
Yini eyenza lokhu kuthakazelise: ukuthi ukusebenza kahle okungu-85-90% kwehlula ezinye izindlela eziningi. Ukugcinwa kwamanzi ampompayo (amanzi ampontshelwa ekukhuphukeni, bese ekhululwa) kufeza ukusebenza kahle okufanayo kodwa kudinga indawo ethile kanye namashumi eminyaka ukuze kwakhiwe. Isitoreji se-hydrogen sizwakala sithembisa kodwa okwamanje sifinyelela kuphela u-30-40% osebenza kahle wohambo lokuya nokubuya. I-BESS ifinyelela endaweni emnandi yokusebenza kahle okuphezulu, isikhathi sokuphendula esisheshayo (ama-millisecond angu-10 kumandla aphelele), kanye nokusetshenziswa okukalayo.
I-S ingeyeSitoreji (Kodwa Ngempela, Imayelana Nesikhathi)
Isitoreji siyingxenye esobala. Kodwa nakhu isifinyezo esingakuthathi: I-BESS ayikona ngempela ukugcina amandla-isikhathi eside. Sekuyisikhathi-sokushintsha.
Ama-solar panel akhiqiza ugesi lapho ilanga likhanya. Abantu badinga ugesi lapho bebuya emsebenzini, bapheke isidlo sakusihlwa, futhi bavule isiphephetha-moya - ngokuvamile amahora ngemva kokushona kwelanga. Leli gebe, elibizwa ngokuthi "ijika ledada" ngenxa yokuma kwalo kumashadi egridi, limele inselele eyisisekelo yamandla avuselelekayo. I-BESS iyixazulula ngokugcina i-solar yasemini futhi iyikhulule ngesikhathi sokuphakama kwesidingo sakusihlwa.
Ngo-2024, amasistimu e-California BESS agcina ngokuhlanganyela amahora angaphezu kwama-gigawatt-amahora angu-30 nsuku zonke, isikhathi{3}}eshintsha amanani amakhulu okukhiqizwa kwelanga abe ngamahora akusihlwa. Izinhlelo zase-Texas zinikeze i-gigawatt engu-1 yokukhishwa okuphuthumayo ngesikhathi seqhwa lika-February, ekhuphuka ngokushesha kunanoma yisiphi isitshalo sikaphethiloli. Lezi akuzona izinzuzo zethiyori - ziyalinganiswa, amandla afakazelwe lezo opharetha begridi manje abancike kuwo.
I-S eyeSistimu (Ingxenye Wonke Umuntu Ayinakwa)
Le "S" yesibili yilapho ukuqonda kwabantu abaningi kwephuka khona. I-BESS akuwona nje amabhethri. Iwuhlelo oludidiyelwe oluqukethe okungenani izingxenye eziyisithupha ezibalulekile:
Amaseli ebhethri namamojula→ Amayunithi angempela okugcina amandla, ngokuvamile i-lithium-ion namuhla
Isistimu Yokuguqula Amandla (PCS)→ Iguqula i-DC (ibhethri) ibe yi-AC (igridi) futhi ibuye
Uhlelo Lokuphatha Ibhethri (BMS)→ Iqapha izinga lokushisa, i-voltage, isimo sokushaja ezinkulungwaneni zamaseli
Uhlelo Lokuphatha Amandla (EMS)→ Ihlanganisa ukuthi kushajwa nini, kukhishwe nini, nokuthi malini
Ukuphatha okushisayo→ Igcina amabhethri ezingeni lokushisa elilungile (ukuvimbela umlilo kuyibhizinisi elibucayi)
Imishini yokuxhumana yegridi→ Ama-Transformer, i-switchgear, ne-hardware yokuxhuma
Ngokusho kokuhlaziywa kwemakethe yaseYurophu yango-2025, amabhethri ngokwawo amele kuphela ama-35% ezindleko zesistimu. Enye i-65% iya kuma-electronics (15%), ibhalansi yezinto zemishini (15%), ingqalasizinda (20%), kanye nokufakwa (15%). Lokhu kuchaza ukuthi kungani ukuthola amaseli ebhethri ashibhile kungenzi ngokuzenzakalela i-BESS ikwazi ukuthengeka - udinga ukuncishiswa kwezindleko kulo lonke uhlelo.
Kungani I-BESS Ibaluleke Kakhulu Kuneziphakamiso Ze-Acronym
Nali iqiniso elingakhululekile mayelana namandla avuselelekayo okungekho muntu obefuna ukulivuma kuze kube muva nje: ilanga nomoya kuyahamba kancane. Ilanga alikhiphi njalo. Umoya awuhambi njalo. Futhi amagridi kagesi adinga ibhalansi ephelele phakathi kokunikezwa kanye nokufuna i-millisecond ngayinye, noma ayawa.
Emashumini eminyaka, le nkinga yezikhawu yenze okuvuselelekayo kungezelelwe kahle kakhulu. Igesi yemvelo "izitshalo zepeaker" - ezibizayo, amajeneretha angcolisayo abekwazi ukuphenduka ngokushesha - abambe izikhala. I-BESS ishintshe isibalo ngokuphelele.
I-Grid Stability Revolution
Amagridi kagesi asebenza kumafrikhwensi anembile (60 Hz eNyakatho Melika, 50 Hz eYurophu). Lapho ukunikezwa kwehla noma ukukhuphuka kwesidingo, imvamisa iyachezuka, okungase kubangele ukwehluleka kwe-cascading kanye nokucisha ugesi. Amajeneretha endabuko azinzisa imvamisa ngobuningi obuzungezayo - izinjini zomoya ezinkulu ezimelana nokushintsha okungazelelwe.
I-BESS inikeza ukulawulwa kwemvamisa ngama-elekthronikhi, hhayi ngobuningi. Iphendula ngaphansi kwama-millisecond angu-10, uma kuqhathaniswa namasekhondi angu-10-15 wezinjini zegesi. Lo mehluko obonakala umncane unemiphumela emikhulu. Ucwaningo lwegridi ye-Taiwan Power Company lubonise ukuthi ukungeza i-BESS kwehlise inkomba yokuthembeka ye-SAIDI isuka ku-14.936 yaya ku-11.978 kanye nenkomba ye-SAIFI isuka ku-0.185 iye ku-0.151 - ehumushela ekucimeni okumbalwa kanye nokubuyisela ngokushesha uma izinkinga zenzeka.
Uguquko Kwezomnotho
Ake sikhulume ngemali, ngoba yilokho empeleni okushayela ukuthunyelwa. I-BESS inika amandla imithombo yemali emithathu ehlukene:
Amandla arbitrage→ Thenga ugesi lapho amanani entengo ephansi (imvamisa engemihle ngesikhathi sokukhiqizwa okuphezulu kwelanga), thengisa lapho amanani entengo ephezulu. Kwezinye izimakethe, lokhu kukodwa kungakhiqiza imbuyiselo yonyaka eyi-15-20% ekutshalweni kwezimali.
Izinkonzo ezisizayo→ Amagridi akhokhela ukulawulwa kwamafrikhwensi, ukusekelwa kwe-voltage, namandla okugodla okuphotha. I-BESS idlula zonke izinto ezintathu, idala imali engenayo engashintshile ngaphandle kwezintengo zamandla.
Izinkokhelo zamandla→ Ama-opharetha egridi akhokhela nje ukuba nesitoreji esitholakalayo phakathi nezikhathi zokudingeka kakhulu, ngisho noma singaphumi.
Uma unqwabelanisa le mithombo yemali engenayo, i-BESS iba ngokuncintisana ngokwezomnotho nezitshalo ezihamba phambili zamafutha ezinsalela nangaphambi kokucabangela izinzuzo zemvelo. Ukuhlaziywa kuka-2024 kubonise amaphrojekthi e-California BESS azuza amanani angaphakathi embuyiselo angaphezu kuka-12%, ngokwehla kwezindleko zemishini ephusha imbuyiselo ephakeme nakakhulu.
I-Global BESS Ukuqhuma: Izinombolo Ezixoxa Indaba Yangempela
Izibalo zokukhula kwe-BESS ziyamangaza ngempela, nakuba zingavamile ukwethulwa ndawonye:
Ukusheshisa ukusetshenziswa→ Ukufakwa komhlaba wonke kukhule ngo-53% ngo-2024 kwafinyelela cishe emahoreni angu-200-emagigawathi, namaphrojekthi angaphezu kuka-400 GWh asendleleni ka-2025 (Rho Motion, January 2025)
Ukwehla kwezindleko→ Izindleko ezisezingeni elilinganisiwe zokulondoloza zehle zisuka ku-$150/MWh ngo-2020 zaya ku-$117/MWh ngo-2023, abahlaziyi behlela ukuqhubeka kwezikhathi zokwehliswa kwesigamu seminyaka emi-4 (Ukuphathwa Kwemininingwane Yamandla)
Ukuthuthukiswa kokuphepha→ Amazinga okuhluleka kwe-BESS ehle ngo-97% phakathi kuka-2018 no-2023, kusukela ekuhlulekeni okungu-9.2 ngegigawathi ngayinye esetshenziswe kuya ekuhlulekeni okungu-0.2 ngegigawathi ngayinye (ucwaningo lwe-EPRI, Meyi 2024)
Ukugxila emakethe→ I-China yasebenzisa u-108 GWh wegridi-yesikali se-BESS ngo-2024, okuhlanganisa u-59% womthamo womhlaba. I-US yengeze i-40 GWh, igxile kakhulu eCalifornia naseTexas. I-Europe ikhule ngo-110% unyaka{10}ngonyaka{11}}kodwa isalandela ngamanani aphelele.
Ukushintsha kweKhemistry→ Amabhethri e-Lithium iron phosphate (LFP) manje asengamele ukusetshenziswa{0}}kokusetshenziswa kwesikali, athatha isabelo semakethe esingaphezu kuka-90% ngenxa yezindleko eziphansi, ukuphepha okuphakeme, nempilo yomjikelezo omude uma kuqhathaniswa namakhemistri{2}asekelwe ku-nickel.
Lokhu akukona ukuqagela noma izibikezelo. Lokhu ukuthunyelwa okulinganiselwe okwenzeka ngo-2024-2025.
Yini eyenza i-BESS Ihluke Kobunye Ubuchwepheshe Besitoreji
Ukugcinwa kwamandla sekuneminyaka engaphezu kwekhulu. Isitoreji sikagesi ompompa amanzi - sidonsa amanzi ekukhuphukeni lapho amandla eshibhile, akhishwe ngama-turbines lapho amandla emba eqolo - kusukela ngeminyaka yawo-1890s. Yini eyenza i-BESS ihluke?
Isivinini→ I-BESS iphendula ngamamillisecond angu-10. I-hydro pumped ithatha imizuzu eyi-10 ukukhuphuka. Lowo mehluko ongu-60,000x ubalulekile ekuzinzeni kwegridi.
Ukuvumelana nezimo→ I-hydro pumped idinga izintaba namanzi. I-BESS ifaka noma yikuphi ngoxhumo lwegridi - ezindaweni zasemadolobheni, izingwadule, izingosi zezimboni.
I-Modularity→ Qala ngamamegawathi ayi-10, unwebe uye ku-100 kamuva. Zama lokho ngedamu eliphehla ugesi.
Ukusebenza kahle kohambo-lokubuya→ I-BESS ifinyelela ukusebenza kahle okungu-85-90%. I-hydro pumped ifinyelela ku-80%, umoya ocindezelwe ngu-40-52%, i-hydrogen 30-40%.
Nansi into-ekhishiwe yokuhweba: izitolo zamanzi ezimpontshwa izinsuku noma amaviki ngesilinganiso esikhulu (i-Bath County Pumped Storage Station e-Virginia ibamba u-24,000 MWh). Ukufakwa okuningi kwe-BESS kunikeza amahora angu-1-4 esitoreji. Ubuchwepheshe bufeza izinhloso ezehlukene. I-BESS ihamba phambili ekuphenduleni okusheshayo nokuhamba ngebhayisikili nsuku zonke. I-hydro pumped ibamba isitoreji sesizini eside.
Ukucwaninga-ubude besikhathi BESS kuyaqhubeka. Amabhethri agelezayo - agcina amandla kuma-electrolyte awuketshezi - angakwazi ukugcina amandla amaviki ambalwa. Ibhethri eligeleza le-vanadium redox elingu-175 MW / 700 MWh lavulwa e-China ngo-2024, elidizayinelwe ukukhipha-amahora angu-4. Amabhethri esimo esiqinile{12} athembisa ukuminyana kwamandla aphezulu nokuphepha. Amabhethri e-sodium-ion anikeza izindleko eziphansi kusetshenziswa izinto eziningi.
Kodwa okwamanje, i-lithium-ion BESS iyabusa ngoba isebenza namuhla ngezindleko eziphusile enokwethembeka okuqinisekisiwe.
Izinselelo Ezifihliwe Akekho Okhuluma Ngazo
Ukufunda izinto zokuphromotha, ungacabanga ukuthi i-BESS ixazulula yonke into kahle. Iqiniso liyi-messier.
Ingozi Yomlilo Engeke Inyamalale
Amabhethri e-Lithium{0}}ion angasha. Akuvamile ukuthi - amazinga okuhluleka ehla abe ngu-0.2 ngegigawathi ngayinye esetshenziswe ngo-2023. Kodwa uma ehluleka, kuba nzima ukucisha imililo futhi ingavutha ngemva kwamahora ambalwa. Ukuqhuma kuka-2019 Arizona BESS okulimaza izicishamlilo kanye nomlilo wango-2021 we-Moss Landing owavala isistimu yebhethri enkulu kunazo zonke emhlabeni izinyanga kufakazela ukuthi lokhu akulona inkolelo-mbono.
Imboni isiphendulile. Izinhlelo zokucisha umlilo zaba ngcono kakhulu. Ukuhlolwa kwefekthri ngo-2024 kuhlonze izinkinga zocisha umlilo kumayunithi angu-28% ngaphambi kokuthunyelwa - kokuthola izinkinga ngaphambi kokuthi zibe izigameko. I-Lithium iron phosphate chemistry, manje esezingeni, ishisa kancane kunezinye izindlela ezisekelwe ku-nickel{6}}.
Noma kunjalo, ingozi ikhona. Ukuphikiswa komphakathi kumaphrojekthi we-BESS kuvame ukugxila ekukhathazekeni ngokuphepha emlilweni, hhayi ngaphandle kwesizathu. Ubuchwepheshe buphephe kakhudlwana kunaseminyakeni emihlanu edlule, kodwa "ukuphepha" akusho "ukuphepha ngokuphelele."
Inkinga Yesimo Sokukhokhiswa
Ukulinganisa ukuthi mangakanani amandla asele ebhethrini le-lithium iron phosphate kunzima ngokumangalisayo. Ngokungafani namabhethri e-lithium nickel manganese cobalt (acishe abe nobudlelwano bomugqa we-voltage{1}}nobudlelwano bokushaja), amabhethri e-LFP agcina i-voltage ecishe ibe njalo kulo lonke uhla lokushaja lwawo. Amaphutha esilinganiso se-State of Charge (SOC) angadlula u-15%, ngokocwaningo lwakamuva.
Kungani lokhu kubalulekile? Ukufundwa kwe-SOC okungalungile kuholela ekushiyeni umthamo ungasetshenzisiwe (imali engenayo elahlekile) noma ngaphezulu{0}}amabhethri akhiphayo (isikhathi sokuphila esifinyeziwe). Lena akuyona inkinga ye-physics - inkinga yokulinganisa kanye nokulawula. Kepha kuthinta wonke opharetha we-LFP BESS, edla buthule ekubuyiseleni okucatshangelwayo.
I-Integration Complexity Crisis
Nasi izibalo okufanele zikhathaze noma ubani osebenzisa i-BESS: 65% wokwehluleka okubhaliwe kuvela ezinkingeni zokusebenza nokuhlanganiswa, hhayi ukwehluleka kwebhethri (EPRI, 2024). Amabhethri asebenza kahle. Isofthiwe, izilawuli, ukuhlanganiswa kwegridi, nezinqubo zokuthuma kudala izinkinga eziningi.
Ukusetha i-BESS kudinga ukuxhumanisa abakhiqizi bebhethri, abahlinzeki bezinto zikagesi zamandla, izihlanganisi zesistimu, ama-opharetha wegridi, neziphathimandla ezilawulayo. Ngayinye iletha amazinga ahlukene, izimiso zokuxhumana, kanye nokuqagela. Uma okuthile kungahambi kahle - isilungiselelo esingalungiselelwe kahle, i-firmware engahambelani, ipharamitha engalungile - izimpawu ngokuvamile aziveli kuze kube amasonto noma izinyanga ngemva kokusebenza.
Imboni isebenza ngokushesha, ithuthukisa amazinga angcono nezinhlelo zokuqeqesha. Kodwa igebe phakathi "kwamabhethri asebenza elebhu" kanye "namasistimu asebenza ngokwethembeka iminyaka engu-20 emkhakheni" lihlala lilikhulu kunalokho abaningi abakuvumayo.
I-Real-World BESS: Lapho Isebenza Khona Empeleni
Ithiyori ibalulekile ngaphansi kwemiphumela. Ingabe i-BESS iphumelela kuphi ngempela?
I-California: I-BESS Laboratory
I-California ikhiphe u-20 GWh wegridi-yesikali se-BESS ngo-2024, emele uhhafu wesamba sokufakwa kwe-US. Amagunya ombuso anamandla avuselelekayo (ugesi ohlanzekile ngo-100% ngo-2045) kuhlanganiswe namanani aphezulu kagesi kudala izimo ezifanele zezomnotho ze-BESS.
Phakathi neziqongo zakusihlwa zasehlobo, lapho ukukhiqizwa kwamandla elanga kwehla kuya kuqanda kodwa isidingo somoya somoya sikhuphuka, imikhumbi ye-BESS yaseCalifornia ihlinzeka ngokuqhubekayo ngamagigawathi angu-5-7 wamandla okukhipha. Lokhu kuthathe indawo yesidingo sezimboni eziningi zegesi, ukuvimbela ukukhishwa kwe-CO2 okulinganiselwa ezigidini ezi-2.5 ngonyaka kuyilapho kunciphisa amanani kagesi wezitolo ezinkulu ngezikhathi eziphakeme kakhulu.
Imodeli yezomnotho iyasebenza: Amaphrojekthi we-California BESS afinyelela izici zamandla azungeze u-25-30% kanye namazinga angaphakathi embuyiselo adlula i-12%. Uma ungakwazi ukushaja amabhethri ngo-$20/MWh phakathi nezinsuku zokugcwala kwelanga futhi aphume ngo-$200+/MWh phakathi neziqongo zakusihlwa, izibalo ziyaphoqa.
I-Texas: Ukufakazela Ukwethembeka Ngaphansi Kokucindezeleka
I-Texas yengeze i-13 GWh ngo-2024, yagxila kugridi ye-ERCOT ehluleke ngokudabukisayo ngesikhathi seqhwa ngoFebhuwari 2021. Ngenkathi enye i-snap ebandayo ifika ngoFebhuwari 2024, i-BESS yenza. Amasistimu esitoreji akhuphuke cishe ngo-1 GW ngemizuzu, agcwalisa izikhala ngokucisha ugesi futhi avimbela ukucisha okubanzi.
Lokhu bekungelona usekelo lwegridi. Lena bekuyimpendulo yangempela yezimo eziphuthumayo, ethathwe kudatha yokusebenza ye-ERCOT. Ukufakwa kwe-Texas BESS manje kumela ingqalasizinda ebalulekile yokwethembeka, hhayi nje amathuluzi okuthuthukisa umnotho.
I-China: -Ukuthunyelwa Kwesikali
I-China i-108 GWh yomthamo omusha we-BESS ngo-2024 imncane kuwo wonke amanye amazwe. Isikali sivumela ukuhlola kungenzeki kwenye indawo. I-50 MW / 100 MWh sodium-ion BESS - enkulu kunazo zonke emhlabeni esebenzisa leyo khemistri - yaqala ukusebenza esifundazweni sase-Hubei ngo-2024. Amaphrojekthi amaningi we-gigawatt{10}}amahora asebenzisa amabhethri e-lithium iron phosphate afike ku-inthanethi. Amandla okukhiqiza aseShayina awo womabili amabhethri nezinhlelo ze-BESS adala abiza u-30-40% ngaphansi kwezimakethe zaseNtshonalanga.
Indlela yokwenza ihluke ezimakethe zaseNtshonalanga. Ukuthunyelwa kwe-BESS yamaShayina kuvame ukubhangqwa ngokuqondile nezitshalo zamandla avuselelekayo, okugunyazwe inqubomgomo kahulumeni. Izidingo zokuhlanganisa (imvamisa amahora angu-2-4 esitoreji ngemegawathi ngayinye yomthamo ovuselelekayo) ziqinisekisa ukuthi ukuthunyelwa kwe-BESS kulandelela ukunwetshwa okuvuselelekayo.
I-Project Lightyear: I-Pharmaceutical Zero-Impumelelo Yekhabhoni
Kwesinye isikhathi izibonelo eziyizimo eziveza kakhulu-ziyisilinganiso esincane. I-United Therapeutics' Project Lightyear eNyakatho ye-Carolina izuze iqanda-ukusebenza kwe-carbon warehouse isebenzisa isistimu yokwenza isipele ye-BESS yamahora angu-48 ehlanganiswe namaphaneli elanga. Lesi sikhungo sigcina ukulawulwa kwezinga lokushisa okuqinile kwemithi ngaphandle kwanoma iyiphi i-fossil fuel backup - awekho igesi yemvelo, awekho amajeneretha edizili.
Le phrojekthi ibonisa i-BESS evumela amamodeli okusebenza ngaphambilini ayengenakwenzeka. Uma ikhwalithi yamandla ekhophi yasenqolobaneni ibaluleke ngaphezu kwezindleko, lapho izibopho zokusimama zingaxoxiswana-, i-BESS inikeza izixazululo ebezingekho eminyakeni emihlanu edlule.
I-Competing Technologies BESS Must Beat
I-BESS ayisebenzi endaweni engenalutho. Ubuchwepheshe obuningi buqhudelana ngemakethe yesitoreji segridi efanayo:
Isitoreji samanzi esimpompa→ 200 GW emhlabeni jikelele, 9,000 GWh umthamo. Ibusa isikhathi eside{4}sesitoreji kodwa ikhawulelwe ngokwendawo futhi iyashesha ukwakha.
Isitoreji samandla omoya acindezelwe (CAES)→ Igcina amandla ngokucindezela umoya emigedeni engaphansi komhlaba. Izitshalo ezimbili kuphela ezisebenzayo emhlabeni wonke ngenxa yezidingo ze-geological.
Isitoreji se-hydrogen→ Guqula ugesi ube yi-hydrogen, gcina, guqulela emuva lapho kudingeka. 30-40% ukuya nokubuya{1}}ukusebenza kahle kohambo kanye nezindleko ezinkulu zokunciphisa ukuthunyelwa, nakuba ucwaningo lusaqhubeka.
Amabhethri agelezayo→ Gcina amandla kuma-electrolyte awuketshezi. Ngokucatshangelwa ubude besikhathi obunganqunyelwe kodwa izindleko eziphezulu kanye nokuminyana kwamandla okuphansi kune-lithium-ion.
Isitoreji esishisayo→ Gcina ukushisa noma ukubanda ukuze ukusebenzise kamuva. Isebenzela izinhlelo ezithile kodwa ayinikezi igridi{1}}yesikali sokugcina ugesi.
Ama-Flywheels→ Gcina amandla kusisindo sokuphotha. Kuhle kakhulu-ezinhlelweni zokusebenza zesikhathi esifushane (amasekhondi ukuya kumaminithi) kodwa awekho ukonga amahora{2}}okugcina isikhathi eside.
Ubuchwepheshe ngamunye bunezinzuzo. Akukho okufana nenhlanganisela ye-BESS yesivinini sokuphendula, ukusebenza kahle, imodularity, namathrendi ezindleko zamanje. Umbuzo awukona ukuthi i-BESS ibusa isikhathi esifushane-(ihora elingu-1-ihora elingu-4) - isivele ibusa. Umbuzo uwukuthi ingabe ukuncishiswa kwezindleko nokuthuthukiswa kwesikhathi kuzovumela i-BESS ukuthi ithwebule izimakethe zesitoreji sesikhathi eside.
Ungacabanga Kanjani Ngendima Yekusasa Le-BESS
Ukubikezela ikusasa lobuchwepheshe kuyingozi. Abagxeki belanga ngo-2010 bacabanga ukuthi izindleko azikwazanga ukwehla ngaphansi kwe-$2/watt. Bashaye u-$0.20/watt ngo-2024. Abagxeki bomoya bathi amapulazi angaphesheya kwezilwandle awanawo umnotho. Manje sebeletha ugesi oshibhe kakhulu eYurophu.
I-BESS ilandela izindlela ezifanayo. Cabangela lezi zibikezelo ngokucophelela:
Ukukhula kwemakethe→ Izibikezelo eziningi zibikezela i-terawatt engu-1 / 3 amahora we-terawatt-omthamo womhlaba ngo-2035, cishe ngokuphindwe kasikhombisa kumazinga ka-2024. I-Wood Mackenzie, i-BloombergNEF, ne-IEA zonke zikhiqiza ububanzi obufanayo naphezu kwezindlela ezahlukene.
Ukwehliswa kwezindleko→ Izindleko zephekhi yebhethri zehlele ku-$115/kWh ngo-2024, kwathi u-$100/kWh wephulwa ngo-2025 kanye nokuqagela okubonisa u-$70/kWh ngo-2030. Kulawo manani, i-BESS iba nokuncintisana ngokomnotho ngesitoreji samahora angu-8-12, hhayi nje amahora angu-2-4.
I-Chemistry evolution→ I-lithium iron phosphate ibusa namuhla. I-sodium-i-ion kanye namabhethri esimo esiqinile{2}}athengiswa ngo-2025-2027. Ngamunye uthembisa izinzuzo ezahlukene - izindleko eziphansi, ukuphakama kwamandla aphezulu, ukuphepha okuthuthukisiwe.
Ukuziphendukela kwemakethe→ Imali engenayo ye-BESS yanamuhla ivela kakhulu ku-arbitrage kanye nezinsiza ezihambisanayo. Izinhlelo zokusebenza zakusasa zihlanganisa ukuhlehliswa kokudluliselwa (ukugwema ukuthuthukiswa kwegridi ebizayo), ama-microgrid emiphakathi ekude, kanye nokuhlanganiswa kwemoto{-ku{2}}kugridi njengoba izimoto zikagesi zanda.
Ukunwetshwa kwendawo→ I-California ne-Texas ngeke zibuse unomphela. I-Australia, iJalimane, iJapane, ne-India zonke zinezimakethe ze-BESS ezikhula ngokushesha. Amazwe anamanani aphezulu kagesi kanye nokungena okunamandla okuvuselelekayo azolandela imodeli yaseCalifornia.
Umzila ubonakala ucacile. Umugqa wesikhathi uhlala ungaqinisekile. Kodwa uma ubuza ukuthi "ingabe i-BESS imeleni," impendulo iya ngokuya iba: ubuchwepheshe obenza amagridi avuselelekayo asebenze ngempela.
imibuzo ejwayelekile ukubuzwa
Imele ini i-BESS ngamagama alula?
I-BESS imele i-Battery Energy Storage System. Kucabange njengebhethri-eyisikali elishajwa kabusha eligcina ugesi oweqile osuka kugridi noma emithonjeni evuselelekayo, bese liwukhulula lapho kudingeka ukuze kulinganiswe ukuhlinzekwa kanye nokufunwa.
Ihluke kanjani i-BESS kunebhethri elivamile?
Isikali, inkimbinkimbi, kanye nenjongo. Ukufakwa kwe-BESS kuqukethe izinkulungwane zamaseli ebhethri, amandla kagesi asezingeni eliphezulu, amasistimu okuphatha okushisayo, nezinto zokusebenza zokuhlanganisa igridi. Idizayinelwe iminyaka engu-20+ yokuphila ukuphatha izinkulungwane zenkokhelo-imijikelezo yokukhipha, ngokungafani namabhethri omthengi enzelwe iminyaka engu-2-5 yokusetshenziswa okulula.
Kungani izinhlelo ze-BESS zibaluleke kangaka kumandla avuselelekayo?
Ama-solar panel akhiqiza ugesi kuphela lapho kukhanya ilanga. Izinjini zomoya zisebenza kuphela lapho kuvunguza umoya. I-BESS igcina amandla uma isizukulwane siphezulu futhi iwakhipha lapho isizukulwane siphansi, okwenza ugesi ovuselelekayo utholakale 24/7 esikhundleni sokuthi kuphela uma imvelo ibambisana.
Iyiphi ingozi enkulu ngokufakwa kwe-BESS?
Ukuphepha komlilo kusewukukhathazeka okuyinhloko. Amabhethri e-Lithium-ion angabamba umlilo uma onakalisiwe, eshajwe ngokweqile, noma epholile ngokungafanele. Izinhlelo zesimanje zihlanganisa ukucisha umlilo okubanzi, kodwa ingozi ayikanyamalala ngokuphelele. Amazinga okufeyila ehle ngo-97% phakathi kuka-2018 no-2023 njengoba imboni ifunde emaphutheni okuqala.
Isistimu ye-BESS ihlala isikhathi esingakanani?
Izinsiza eziningi-zesikali sezinhlelo ze-BESS ziqinisekiswa iminyaka engu-10-20, ngokuvamile neziqinisekiso zomthamo. Ubude bangempela bempilo buncike ekusetshenzisweni - kokugibela ibhayisikili okunamandla kwehlisa isithunzi amabhethri ngokushesha kunokusebenza okulula. Amasistimu aphethwe kahle kufanele anikeze iminyaka eyi-15-20 yokusebenza okunenzuzo kwezomnotho ngaphambi kokudinga ukushintshwa.
Ingabe i-BESS ingayenza imali?
Yebo, ngokusebenzisa imithombo eminingi yemali engenayo: i-arbitrage yamandla (ukuthenga okuphansi, ukuthengisa okuphezulu), izinsizakalo zegridi (ukulawula imvamisa, ukusekelwa kwamandla kagesi), nezinkokhelo zamandla (inkokhelo yokutholakala ngesikhathi seziqongo). Amaphrojekthi ase-California ahlala afinyelela ku-12-15% amanani wangaphakathi wembuyiselo ngaphansi kwezimo zemakethe zamanje.
Kwenzekani uma amabhethri e-BESS eguga?
Izinketho zifaka phakathi ukugaywa kabusha (ukuthola kabusha izinto ezibalulekile njenge-lithium ne-cobalt) noma-izinhlelo zokusebenza zempilo yesibili (ukusebenzisa amabhethri awonakele ezinhlelweni zokusebenza ezingafuneki kangako ngaphambi kokuvuselelwa kokugcina). Izinhlelo zesibili ze-EV zomkhakha webhethri-zokudala izindlela zamabhethri e-BESS asethathe umhlalaphansi nawo, nakuba izinto eziningi ezisetshenziswayo-ukufakwa kwesikali kukusha kakhulu ukuthi kungafinyeleli esiphethweni{{4}se{5}}sempilo okwamanje.
Okubalulekile: I-BESS Ayiseyona Inketho
Uma uqonda ukuthi i-BESS imeleni - uqonda ngempela uhlelo oluphelele kanye nendima yalo ekuguquleni igridi - uyabona ukuthi asikhulumi ngobuchwepheshe be-niche noma ukuthuthukisa ongakukhetha. I-BESS imele ingqalasizinda eyisisekelo yamagridi anamandla avuselelekayo{{3}.
Iminyaka eyishumi ezayo izobona ukuthunyelwa kwe-BESS kushesha ukudlula izilinganiso zamanje. Izindleko zebhethri zizoqhubeka nokwehla. Ukuphepha kuzothuthuka. Ubude besikhathi buzokwelulwa. Futhi umbuzo ngeke ube "yini i-BESS imele" kodwa kunalokho "sake sasebenzisa kanjani amagridi ngaphandle kwayo?"
Izinto ezintathu eziqondile okufanele zibukwe: Okokuqala, ukuhlanganiswa kwe-BESS nemoto-kumasistimu-egridi (V2G) njengezikali zokwamukela imoto kagesi. Okwesibili, ukumataniswa kwe-BESS nokukhiqizwa kwe-hydrogen eluhlaza ukuze kuxazululwe inselele yesitoreji evuselelekayo ebhekene nayo. Okwesithathu, ukuvela-kwesilinganiso kanye nendawo yokuhlala ye-BESS eyenza intando yeningi ukubamba iqhaza kwegridi.
Uma uhlola i-BESS yezinhlelo zokusebenza zezentengiso, ezomnotho cishe sezivele zisebenza{0}ezifundeni ezibiza kakhulu-zikagesi. Uma ukunqubomgomo yamandla, ukunika amandla imvume ye-BESS esheshayo nemithetho yemakethe ecacile kuzosheshisa ukuthunyelwa ngaphezu kwezibonelelo. Uma ubukele ukushintsha kwamandla usuka eceleni, qonda ukuthi i-BESS ubuchwepheshe obuyenza ikwazi ukusebenza ngobuchwepheshe.
Isifinyezo singazwakala siyisicefe. Ubuchwepheshe bokuguqula amagridi kagesi buyilutho.
