Ngokwemibiko yezindaba zakwamanye amazwe, ngoMeyi 15 ngesikhathi sendawo, kwaqubuka umlilo endaweni yokugcina amandla e-Gateway e-Otay Mesa, eSan Diego, eCalifornia, eU.SA.Kuthathe izicishamlilo isikhathi esingaphezu kosuku ukulawula umlilo, kodwa ibhethri kulesi sikhungo seliphinde lasebenza izikhathi eziningi.
Ngokwemibiko yabezindaba yangaphandle ngoMeyi 21st, isikhungo sokugcina amandla sivutha izinsuku eziyisithupha, futhi izikhulu zomlilo azikakwazi ukulinganisa ngokunembile ukuthi umlilo uzoqhubeka isikhathi esingakanani.
URobert Rezende, umkhuzi weSan Diego Fire and Rescue Bureau kanye nomxhumanisi wezimo eziphuthumayo wamandla ahlukile, uthe ngokomlando, bekujwayelekile ukubona lolu chungechunge lwembubhiso luhlala isikhathi eside, cishe njengomphumela we-domino.
UBrent Pascua, ukaputeni wegatsha laseSan Diego loMnyango Wezomlilo waseCalifornia, naye wathi, “Ngemva kokukhuluma nochwepheshe, baye bahlangabezana nezigameko eziningana ezifanayo esikhathini esidlule, ngasinye esithatha izinsuku eziyisikhombisa kuya emasontweni ambalwa, futhi asiqiniseki.Silungiselela isimo esibi kakhulu futhi sihlela ukuhlala lapha isikhathi eside, amasonto amabili kuya kwamane, bese sihlola kabusha. ”
I-Battery Network yaphawula ukuthi ngo-June 2023, iziteshi ezimbili zokugcina amandla e-lithium-ion eWarwick, eNew York, e-U.S.A., zasha ngesikhathi kunesiphepho, esathatha isikhathi esingaphezu kwesonto.
Ngo-Okthoba 2023, kwaqubuka umlilo endaweni yokugcina amandla kagesi i-Idaho Power eduze kwase-Melba, e-Idaho, e-USA, okwabangela ukuthi okungenani amabhethri azimele angu-8 akhele umlilo.Umlilo udonse izinsuku ezimbalwa.
Kubikwa ukuthi umthamo ofakiwe wesiteshi samandla okugcina amandla iGateway ungu-250MW/250MWh.Ngo-August 2020, isigaba sokuqala salo msebenzi, esinamandla angu-230MW, saqala ukusebenza futhi saba iphrojekthi enkulu kunazo zonke emhlabeni yokugcina amandla ngaleso sikhathi.Le phrojekthi futhi ihlela ukukhula ibe ngu-250MW amahora ama-4, yakhe uhlelo lokugcina amandla angu-1000MWh.
Isiteshi samandla okugcina amandla e-Gateway sisetshenziswa yinkampani yamandla yaseMelika i-LS Power, ne-NEC ES ehlinzeka ngezixazululo zokuhlanganiswa kwesistimu yokugcina amandla kanye ne-LG Chem ehlinzeka ngamaseli ebhethri, okungamabhethri e-ternary lithium.
Kuyafaneleka ukubalula ukuthi kunemibiko ebonisa ukuthi i-NEC ES, umdidiyeli wokugcinwa kwamandla kagesi kulo msebenzi, yamemezela ukushabalala kwezimali futhi yahoxa ebhizinisini lokugcina amandla ngaphambi kokuba kuqale isigaba sokuqala somsebenzi.
Ngaphezu kwalokho, ngenyanga nje edlule (ngo-Ephreli 27th), kwaqubuka umlilo esitsheni se-lithium ibhethri yokugcina amandla etholakala esifundeni sezentengiselwano saseNilmore, eJalimane, okwenza abalimala ababili balimala ngesikhathi senqubo yokuhlenga.
Ngokwemibiko yezindaba efanele, umkhiqizi wesistimu yokugcina amandla ebhethri eqhume ngalesi sikhathi inkampani yaseJalimane i-INTILION, futhi amaseli ebhethri angamabhethri e-lithium iron phosphate.
Ngomhla ziyi-16 kuMbasa, isitoreji sebhethri sase-California saba umthombo owodwa omkhulu kagesi wegridi yamandla yase-California phakathi namahora asebusuku aphakeme okokuqala ngqa ohlelweni lwamandla omhlaba.Iqhaza lokugcinwa kwamandla ekulawuleni imithombo yamandla lidalwe umehluko omkhulu wamanani entengo kagesi aphezulu kanye nesigodi emakethe kagesi yaseCalifornia, enikeza ithuba elikhulu lenzuzo yokugcina amandla.
Kusukela “emcebo nokuchuma okuchichimayo” kuya “ezinhlekeleleni eziwa ezulwini”, izitshalo ezimbili ezinkulu zamandla okugcina amandla zabamba umlilo zilandelana phakathi nenyanga.Izinkinga zokuphepha zokugcinwa kwamandla, okuyithrekhi yomjaho wamadola ayizigidi eziyizinkulungwane ezintathu, azinakuzitshwa!
U-Wu Kai, Usosayensi Omkhulu we-CATL, wake washo ngokungagunci ukuthi njengemboni yengqalasizinda ebalulekile ebandakanya kokubili ukuphepha kwempilo nempahla kanye nokuphepha kokusebenza kwesistimu yamandla, izindleko zokuhlola namaphutha zokugcinwa kwamandla ziphezulu kakhulu;Asikwazi ukulandela indlela endala yokuphishekela isivinini kuqala bese kuba yikhwalithi.Kufanele sibambelele ekuthuthukisweni okuthembekile, okuqhubekayo, kanye nekhwalithi ephezulu yemboni yokugcina amandla kusukela ekuqaleni.
Ulwazi olusesidlangalaleni lubonisa ukuthi izindaba zokuphepha bezilokhu zingenye yezindawo ezibuhlungu ezivimbela ukuthuthukiswa kokugcinwa kwamandla, ithrekhi yamadola ayizigidigidi.Amabhethri e-lithium njengamanje angobunye bobuchwepheshe bebhethri obusetshenziswa kakhulu bokugcina amandla, kodwa ngenxa yokuthi i-electrolyte yamabhethri e-lithium ikakhulukazi izincibilikisi eziphilayo, futhi kukhona ukungcola okumbalwa okunjengothuli olungalimaza kalula isihlukanisi ngesikhathi sokukhiqiza. inqubo, ukubaleka okushisayo kujwayele ukwenzeka, okubangela izifunda ezimfushane zangaphakathi, okuholela ochungechungeni lwezinkinga ezinjengomlilo, ukuqhuma kwebhethri, ukungcoliswa kwemvelo, nokuphazamiseka kokunikezwa kwamandla.
Ngokombono wezinto ezisetshenziswayo, i-electrode esebenzayo yamabhethri e-ternary ngokuvamile i-transition metal oxides.Uma i-electrode enhle ibola, izohambisana nokukhululwa komoya-mpilo.Ngaphansi kokusebenza komoyampilo, i-electrolyte ijwayele ukusabela, okwandisa ubungozi bokubaleka okushisayo kwebhethri uma kuqhathaniswa nezinto zokwakha ze-lithium iron phosphate.
Ezinsukwini zokuqala, izinkampani zamabhethri zaseJapan naseKorea zazivame ukusebenzisa amabhethri e-ternary, kuyilapho izinkampani zamabhethri zaseShayina zazisebenzisa amabhethri e-lithium iron phosphate aphephile.Ngokuvela njalo kwezingozi zokuphepha ezinjengomlilo wokugcina amandla ebhethri ye-ternary, ziyanda izinkampani zaseJapan naseKorea zisebenzisa amabhethri e-lithium iron phosphate.
Ngokwevolumu yokuthunyelwa, ingxenye yokuthunyelwa kwamabhethri okugcina amandla eChina emhlabeni idlule ama-90%.Ngokwe-“White Paper on Development of China’s Energy Storage Industry (2024)” ekhishwe ngokuhlanganyela yizikhungo zocwaningo i-EVTank, i-Ivy Economic Research Institute, kanye ne-China Battery Industry Research Institute, umthamo wokuthunyelwa komhlaba wonke wamabhethri okugcina amandla ufinyelele ku-224.2 GWh ngo-2023 , ukwanda konyaka nonyaka ngama-40.7%.Phakathi kwazo, umthamo wokuthunyelwa kwamabhethri okugcina amandla avela emabhizinisini aseShayina wawungu-203.8 GWh, ohlanganisa u-90.9% wevolumu yokuthunyelwa komhlaba wonke yamabhethri okugcina amandla.
Enye isethi yedatha evela ku-National Energy Administration iphinde ibonise ukuthi kusukela ekupheleni kuka-2023, umthamo ofakiwe wezinhlelo ezintsha zokugcina amandla ezisebenza ezweni lonke usufinyelele kuma-kilowatts ayizigidi ezingu-31.39.Phakathi kwazo, umthamo osanda kufakwa wesitoreji samandla amasha ngo-2023 ungama-kilowatts ayizigidi ezingama-22.6, okuyizikhathi eziyi-2.6 ingqikithi yeminyaka edlule.Ekupheleni kwekota yokuqala yalo nyaka, amandla afakiwe ahlanganisiwe emiklamo emisha yokugcina ugesi akhiwe futhi aqala ukusebenza eShayina isifinyelele ku-35.3 million kilowatts/77.68 million kilowatt hours, okuwukunyuka okungaphezu kuka-210% uma kuqhathaniswa ekupheleni kwekota yokuqala ka-2023.
Nakuba uhlobo olusha lokugcinwa kwamandla luhlanganisa ubuchwepheshe obuhlukahlukene njengamabhethri e-lithium, amabhethri okugeleza, ama-flywheels, umoya ocindezelweyo, isitoreji samandla e-hydrogen (ammonia), isitoreji samandla esishisayo (esibandayo), njll., amabhethri e-lithium asabusa okwamanje.
Ngakho-ke, ngenkathi imboni yokugcina amandla ikhula ngokushesha, i-China nayo ibheka ukubaluleka okukhulu ekuvikelekeni kwezimboni.
NgoJulayi 2023, indinganiso kazwelonke “yemithetho Yokuphepha Yeziteshi Zamandla E-Electrochemical Energy Storage Power” yaqala ukusetshenziswa.Leli zinga likazwelonke elisha lokuphepha kwesitoreji samandla lisebenza kumabhethri e-lithium-ion, amabhethri e-lead-acid (carbon), amabhethri agelezayo, neziteshi zamandla okugcina amandla e-hydrogen/fuel cell cell electrolysis.Leli zinga licacisa izidingo zobuchwepheshe zokuphepha, ukusebenza, ukugcinwa, ukuhlola, ukuhlola, nezinye izici zemishini ehlukahlukene njengamabhethri okugcina amandla esiteshi samandla e-electrochemical, i-BMS, i-PCS, ukuqapha, ukuvikela umlilo, ukushisisa umoya kanye nezinhlelo zokupholisa umoya, ezakhelwe ngaphambili. amakhabethe, njll.
NgoNovemba 2023, uMnyango Ophelele Wokuphathwa Kwezamandla Kazwelonke wakhipha isaziso sokuqinisa ukuqapha ubungozi bokusebenza kokuphepha kweziteshi zamandla okugcina amandla e-electrochemical ohlangothini lokuphehla ugesi lwegridi kagesi, uhlongoza ukuthuthukisa ikhono lokuqapha nokuhlaziya ubungozi bokusebenza kusenesikhathi. isixwayiso.Amabhizinisi asebenza ngogesi kufanele aqaphe futhi aphathe isimo sokuphepha samaphakethe ebhethri esiteshi samandla e-electrochemical energy, amasistimu okuphatha amabhethri (BMS), amasistimu okuphatha amandla (EMS), iziguquli zokugcina amandla (PCS), amasistimu okuvikela umlilo, ukuphepha kwenethiwekhi, indawo yokusebenza, nezinye izinto zikagesi ezibalulekile ezitshalwe futhi zisetshenzwa ngamabhizinisi abo.Kufanele bahlaziye njalo isimo sokusebenza kokuphepha, baqinise isexwayiso sengozi yokusebenza kanye nezimo eziphuthumayo, futhi bakwazi ukuxwayisa ngesikhathi futhi bathathe izinyathelo ezisebenzayo zokuqeda izingozi zokuphepha kwemishini nezinhlelo ezinezingozi zokuphepha.Zonke izinkampani zikagesi kufanele ziqedele ukwakha amandla azo okuqapha ngaphambi komhla zingama-31 kuZibandlela 2024, futhi zonke iziteshi zamandla kagesi we-electrochemical ezintsha nezikhona kufanele zifakwe kuhlelo lokuqapha ngemva kuka-2025.
Phakathi naleso sikhathi, ngaphezu kwezindaba zokuphepha, impi yentengo emkhakheni wamabhethri okugcina amandla iyaqhubeka nokusabalala.Kusukela engxenyeni yesibili ka-2023, intengo yamabhethri okugcina amandla iye yehla ngokuphindaphindiwe, nezinkampani eziningi ezinikeza amaseli okugcina amandla anenani elingaphansi kuka-0.4 yuan/Wh.
Ngomhla ziyi-14 kuNhlaba, i-China Petroleum Group, i-Jichai Power Co., Ltd. yakhipha isimemezelo sebhidi yesivumelwano sohlaka lwezingxenye zikagesi zesistimu yokugcina amandla epholile engu-5MWh.Amaseli ebhethri ephrojekthi asebenzisa amabhethri e-lithium iron phosphate, anomkhawulo wentengo omkhulu ongu-0.33 yuan/Wh.Ekubhideni kwephrojekthi yokugcina amandla ye-Jichai Power ekupheleni kukaFebruwari, umkhawulo wentengo wamaseli ebhethri wawungu-0.45 yuan/Wh.
Muva nje, lapho usebenzisana nabatshalizimali, i-Yiwei Lithium Energy yathi amakhasimende azocabangela imikhiqizo yebhethri yokugcina amandla kusuka ezicini eziningana: okokuqala, umkhiqizo;Okwesibili izinga lomkhiqizo, okuhlanganisa ukusebenza komkhiqizo nokusebenza kokuphepha;Eyesithathu isiqinisekiso sangemva kokuthengisa.Ngakolunye uhlangothi, ibheka ikhono lensizakalo yangemva kokuthengisa yebhizinisi, futhi ngakolunye uhlangothi, ibheka ukuthi ingabe ibhizinisi linamandla okuthuthuka okuzinzile wesikhathi eside.Imikhiqizo yokugcina amandla inomjikelezo wempilo ende, futhi amabhizinisi akhiqiza amabhethri okugcina amandla anganikeza ukusekelwa ngemuva kokuthengisa kwemikhiqizo yawo uma enomjikelezo wempilo ende yokuphila;Ubukhulu bokugcina yintengo yomkhiqizo.
