Qhov xwm txheej: Tsis tu ncua Blaze ntawm lub ntiaj teb Benchmark
Nyob rau nruab nrab -Tsib Hlis 2024, Gateway Energy Storage project hauv Otay Mesa, San Diego, tau los ua lub hauv paus ntawm kev saib xyuas thoob ntiaj teb tom qab muaj hluav taws kub loj. Ib zaug ua kev zoo siab raws li lub ntiaj teb cov roj teeb loj tshaj plaws ntawm lub zog khaws cia (BESS) thaum nws tso tawm xyoo 2020, 250MW qhov chaw tau raug kev txom nyem los ntawm thermal runaway tshwm sim uas kav ntev li ob lub lis piam.
Qhov hnyav ntawm qhov hluav taws kub thiab sib sau ua ke ntawm cov pa phem tau yuam cov tub ceev xwm hauv cheeb tsam tau tshaj tawm cov lus txib kom khiav tawm thiab chaw nyob - hauv - qhov chaw ceeb toom rau cov lag luam nyob ze thiab lub xeev lub tsev loj cuj.
Kev lag luam cuam tshuam: Tightening Safety Standards and Public Trust
Rau lub ntiaj teb lub zog cia kev lag luam, tshwj xeeb tshaj yog kev lag luam thiab kev lag luam (C&I), qhov xwm txheej no yog qhov hloov pauv tseem ceeb. Kev tswj hwm lub cev yuav tsum ua kom nrawm rau kev siv cov cai nruj dua, xws li NFPA 855 tus qauv. Cov tuam txhab tuav pov hwm kuj tseem yuav rov ntsuam xyuas dua cov kev pheej hmoo rau loj - cov phiaj xwm BESS loj, uas tuaj yeem ua rau cov nqi them siab dua thiab kev tshuaj xyuas nruj dua ntawm cov hluav taws kub tua hluav taws thiab cov xov tooj ntawm tes- cov thev naus laus zis ntsuas qib.
Tsis tas li ntawd, qhov hluav taws kub tau ua rau "Tsis Nyob Hauv Kuv Lub Nroog" (NIMBY) kev xav. Qhov hluav taws kub no tuaj yeem ua rau txo qis cov txheej txheem tso cai rau cov haujlwm tshiab raws li cov zej zog hauv zos xav kom muaj kev pom tseeb dua thiab muaj kev ruaj ntseg zoo dua. Cov neeg tsim khoom tam sim no ntsib ob qhov kev sib tw ntawm kev ua pov thawj ob qho tib si kev lag luam thiab kev nyab xeeb ntawm lawv cov kev teeb tsa.
Chemistry Debate: Hloov ntawm NMC mus rau LFP
Lub ntsiab lus tseem ceeb ntawm kev tshaj tawm - kev tshawb nrhiav hluav taws yog cov roj teeb chemistry siv ntawm Gateway: Nickel Manganese Cobalt (NMC) roj teeb. While NMC offers high energy density, it is known for a lower thermal runaway temperature compared to its counterparts. Qhov xwm txheej Otay Mesa tau ua rau muaj kev lag luam loj dua -tawm mus rau Lithium Iron Phosphate (LFP) thev naus laus zis. LFP roj teeb, txawm tias tsawg zog- ntom ntom, muaj kev nyiam ntau dua rau qhov chaw cia khoom vim lawv cov thermal stability zoo dua thiab qis dua qhov kev pheej hmoo ntawm hluav taws.
Qhov kev hloov pauv no yog qhov tshwj xeeb rau Suav C&I cia khw, qhov twg LFP yog tus qauv tseem ceeb. Qhov hluav taws kub hauv California txhawb nqa kev txawj ntse ntawm kev saib xyuas kev nyab xeeb dua li cov khoom siv raw hauv cov ntawv thov nyob ruaj khov. Tsiv mus tom ntej, kev lag luam zoo li yuav pom qhov kev hloov pauv tshiab rau "dhau ntawm-- roj teeb" kev nyab xeeb, suav nrog AI qib siab-tsav kev tswj hwm (BMS) uas tuaj yeem kwv yees kev ua tsis tiav ua ntej lawv tshwm sim, thiab cov qauv tsim qauv uas cais cov roj teeb ntawm tus kheej kom tiv thaiv tib lub xov tooj ntawm tes tsis ua haujlwm los ntawm kev hloov mus rau hauv ib lub lis piam.{5}} ntev.
