Chii Grid-Chikero Mabhatiri Anonyatsoita (Kupfuura Kushambadzira)
Zvizhinji zvinyorwa zvinokupa runyoro rwe "maapplication" pasina kutsanangura kuti nei zvichikosha. Rega ndikuratidze izvo mabhatiri egidhi anonyatso kuita munyika chaiyo.
The Three{{0}Dambudziko reChipiri
Muna 2017, mushure mekunge chirimwa chihombe chemarasha chadonha zvisingatarisirwi, Hornsdale Power Reserve muSouth Australia yakakwanisa kubaya mamegawati akati wandei mugedhi mukati memilliseconds, ichisunga kudonha kwegridi frequency kusvika jenareta yegasi yakwanisa kupindura.
Milliseconds. Kwete maminetsi. Kwete masekonzi. Ndiwo mutsauko uripo pakati pegridi yakagadzikana uye kudzima kwemagetsi kunokanganisa mamirioni.
Hezvino izvo chaizvo zvakaitika: Pakatadza chirimwa chemarasha, grid frequency yakatanga kudonha. Mukuchinjanisa masisitimu azvino, frequency inofanirwa kugara yakagadzikana (60 Hz chaiyo kuNorth America, 50 Hz mune mamwe matunhu mazhinji). Kana frequency inodonha pazasi pechikumbaridzo mazinga, otomatiki masisitimu anotanga kubvisa mitoro kudzivirira kukuvara kwejenareta. Ndiwo mawaniro aunoita madzima emagetsi.
Majenareta echinyakare-kunyangwe anokurumidza-anotora maminitsi gumi kusvika gumi nemashanu kuti akwire. Maturbine egasi anokurumidza asi achiri kuda 5-10 maminetsi. Mabhatiri anopindura mukati mesekondi imwe. Vanotenga nguva yekuti masisitimu anononoka aite.
Izvi hazvisi zvekufungidzira.

Musiyano uyu uri kuunza imwe tekinoroji yakasiyana zvachose.
Iyo Chemistry Revolution
Mabhatiri eGrid anoda mashoma emagetsi kana achienzaniswa neEVs, zvichireva kuti kukoshesa kwakawanda kunogona kuiswa pamitengo, kugona kuchaja uye kuburitsa kazhinji, uye hupenyu hurefu. Izvi zvakonzera shanduko kuenda kumabhatiri elithium iron phosphate (LFP), ayo akachipa uye anogara kwenguva refu kupfuura echinyakare relithium-mabhatiri eion.
Asi LFP ingori kutanga. Matatu ari kusimukira matekinoroji ari kunetsa kutonga kwelithium:
Mabhatiri eSodium-Ion
Sodium-mabhatiri eion haabatike uye anoshandisa zvakachipa, zvisinganyanyi kukosha pane lithium-ion. Ivo vane yakaderera simba density uye pamwe hupenyu hupfupi asi vanogona kudhura 20-30% kana vakagadzirwa pachiyero chimwe chete.
Funga kuti izvozvo zvinorevei. Sodium inotorwa kubva mumvura ine munyu. Hapana kuchera kunodiwa. Hapana geopolitical supply chain njodzi. Makumi maviri kubva muzana kuderedza mutengo. The tradeoff? Iwo makuru uye anorema-asi kune yakamira grid kuchengetedza, ndiani ane hanya? Hausi kuatakura nemota.
Iron-Mabhatiri Emhepo
Iron-mabhatiri emhepo ari kugadzirwa nenguva ye100-awa yekuchengeta pamutengo wesystem inokwikwidzana nemagetsi ekare, aine mapurojekiti azvino ekuyedza senge nzvimbo ye300 MW yeGreat River Energy yakatanga muna 2023.
Verenga izvozvo zvakare: 100-maawa ekuchengetedza. Irizvino lithium masisitimu anodhura kwe2-8 maawa. Iron{{7}mhepo inogona kusvitsa mazuva. Mabhatiri esimbi anovimbisa kuendesa yakaderera-gridi{9}}chikero chekuchengetedza simba rebhatiri, chinosvika chikamu chimwe{12}}chegumi chemutengo unoenzana wekugadzira lithium{13}}ion. Kubata? Tekinoroji haisati yakura. Magadzirirwo echizvarwa chekutanga achiri kuongororwa mumunda.
Kuyerera Mabhatiri
Kusiyana nemabhatiri akajairwa uko simba remagetsi uye kubuda kwesimba kwakabatana, kuyerera mabhatiri anoabvisa. Unoda imwe nguva yekuchengetedza? Wedzera matangi makuru. Unoda mamwe magetsi anobuda? Wedzera mamwe masero. Iyo dhizaini inoshanduka inoshamisa.
Parizvino iron flow battery modules ane 400 kWh simba rekuchengetedza simba, 25-makore ekugadzira hupenyu, uye anogona kugadzirwa kuti ape nguva yekuchengeta ye4-12 maawa. Hupenyu hwemakore makumi maviri nemashanu ndiyo inobata kutarisisa-kaviri izvo lithium masisitimu anowanzo kupa.
Matambudziko Matatu Hapana Anoda Kukurukura
Ini ndinofanira kuenderana newe nezve iyo indasitiri iri kunetsekana. Kwete kusava netariro, asi nekuti kunzwisisa zvipingamupinyi ndiyo nzira yaunoona nayo mikana.
Kuchengeteka Kwemoto: Njodzi Isina Kugadziriswa
Musi waKubvumbi 19, 2019, moto uye kuputika panzvimbo ye2 MWh lithium bhatiri muArizona kwakakuvadza vanodzima moto vasere. Musi waKubvumbi 16, 2021, kuputika kwenzvimbo ye25 MWh muBeijing kwakauraya vadzimi vemoto vaviri. Izvi zvaisava zviitiko zvidiki. Vaive kutadza kukuru kwakauraya nekukuvadza vanotanga kupindura.
Kutiza kwemafuta-apo bhatiri rikapisa nekutungidza maseru evavakidzani mukuita manyama amire nerongo-rinoramba riri dambudziko. Nepo mabhatiri elithium-ioni ari nani pakuchengeta nekubvisa simba, anoisa njodzi dzine njodzi dzakanyanya sekumhanya kwemafuta uye kuburitswa kwehutsi hunokachidza panguva yezviitiko zvemoto, izvo zvinotungamira kumitemo yekuchengetedza yakasimba uye matambudziko ekutonga.
Mapinduriro eindastiri-akamisikidzwa: masisitimu ekutonga kwemafuta akavandudzwa, nzvimbo iri nani yemasero, masisitimu ekudzima moto, nekuongorora kwakakwenenzverwa. Asi ngativei chokwadi{{2}tiri kutonga njodzi, kwete kuibvisa. Ndosaka mamwe machemistries akaita sesodium-ion nemabhatiri ekuyerera ari kutariswa zvakanyanya. Iwo ari masikirwo asingabatike.
The Duration Dilemma
Mabhatiri egrid aripo anogadziridzwa kuti akwanise kunzi "intraday" kuchengetedza-kuchaja kana magetsi akachipa kana akawandisa, achizobuda 4-8 maawa gare gare pazvinenge zvichidiwa. Mahombe-akawanda ekuchengetera masisitimu ari kushanda ane nguva yakawandisa yemaawa 4 uye anoshandisa lithium-ion tekinoroji, inoshanda kuburikidza nemazuva ano arbitrage nekutenga simba mukati memaawa emasikati kana solar yakawanda uye kuitengesa munguva dzemanheru dzinodiwa zvakanyanya.
Izvi zvinoshanda zvakanyanya kuzuva nezuva-mhepo-inoda kuenzanisa. Asi zvakadini -nemazuva akawanda emamiriro ekunze? Zvakadini nekuchengetedza mwaka?
Zveupfumi zviri nyore zvinoratidza kuti lithium-mabhatiri eion haagone kushandiswa kuchengetedza simba remwaka. Pamutengo we $200/kWh bhatiri, $200 trillion inokosha yemabhatiri- kagumi US GDP muna 2020-inongogona kupa chiuru cheTWh chekuchengetedza, ingangoita mari inochengetwa neUS semavhiki matanhatu emafuta emakemikari.
Verenga izvozvo zvakare. Hakusi kuti mwaka wekuchengetedza bhatiri unodhura. Izvo ndezvekuti hazvigoneke mune zvehupfumi neizvino lithium tekinoroji. MaSystem ane zviri pasi pe40% zvinogonekazve zvinongoda kuchengetwa kwenguva pfupi-, asi kupfuura 90% yekupinda zvakare, -nguva yekuchengeta inove yakakosha. Sezvo magidhi anosundira akananga ku80-90% inovandudzwa, ichi chinomanikidza chinova chinosunga.

Hechino chokwadi chisingafadzi: Zvose EV negridi-masekita emagetsi anotsamira pazvinhu zvakafanana selithium, cobalt, uye nickel. Uyezve, makambani mashoma chete anodzora lithium-ion bhatiri rekupa zvikamu zvese zviri zviviri.
Kana kugadzirwa kweEV kwakakwira muna 2021-2022, mitengo yelithium yakawedzera. Grid kuchengetedza mapurojekiti akangoerekana atarisana nemutengo wekuwedzera we30-50%. Kunyange mutengo webhatiri wakadzikira zvakanyanya nekuda kwekukwira kwekugadzirwa kwemotokari yemagetsi, kukanganisa kwemusika uye kukwikwidza kubva kune vagadziri veEV kwakonzera kukwira kwemitengo yemaminerari akakosha anoshandiswa mukugadzirwa kwebhatiri, kunyanya lithium.
Iyi haisi nyaya yenguva pfupi. Tiri kutaura pamusoro pezvakakosha zvishongedzo. US inobata 1.8 miriyoni metric tons yelithium reserves-ingori 6% yepasi rose. Nezvemamiriro ekunze, zero{{6}kabhoni remangwana panosvika 2050 rinoda 930 GW yenzvimbo yekuchengetera muUS, grid ichida 225-460 GW yenguva refu yekuchengeta simba.

MaGridi anorova "sirin'i yekuchengetera" pa50-60% inogoneka kupinda mukati, iine huwandu hwasara hwakazadzwa nenyukireya, hydrogen, kana kuenderera mberi nekushandiswa kwemafuta necarbon capture. Kukura mukuiswa kwebhatiri kunononoka mushure me2030 se "michero yakarembera" maapplication achizara.
Chii chinoitika? Izvo zvinoenderana nemhando mbiri dzakakosha:
Tekinoroji yekuvandudza nguva: Ko mabhatiri earon-emhepo kana anoyerera epamusoro anobudirira mukutengesera panosvika 2027-2028, kana kuti anoramba ari "makore mashanu kubva"?
Mineral supply response: Ko lithium, cobalt, uye nickel yekugadzira chiyero nekukurumidza zvakakwana kuti itsigire EV uye gidhi rekuchengetedza kukura, kana kuti zvipingamupinyi zvekupa zvinomanikidza pivot kune mamwe makemikari?
Kuverenga kwangu: Isu tave kunyanya kunanga kumhando yakasanganiswa-lithium inotonga nguva pfupi-yekushandisa kusvika muna 2030, asi mamwe machemistries anotora 30-40% yemusika sezvo zvinodiwa zvenguva zvichiwedzera uye zvimhingamipinyi zvezvishandiso zvinoruma.
Kunzwisisa "Nei"
Saka ngatidzokere kumubvunzo wekutanga: Sei uchishandisira grid{{0}chiyero chekuchengetedza simba rebhatiri?
Nokuti imwe nzira yacho yakaipa.Izvo hazvisi zvekutaura{{0}ichokwadi cheinjiniya.
Pasina kuchengetedza, kupinza kwepamusoro kunogoneka kunova kusingagoneke nemasvomhu. Unorova sirin'i kusvika 30-40% inovandudzwa uko kusagadzikana kwegridi kunova kusingatarisike. Chero giredhi remagetsi emagetsi rinofanirwa kuenderana nekugadzirwa kwemagetsi nekushandisa, ese ari maviri anosiyana zvakanyanya nekufamba kwenguva, uye yakaderera-kabhoni magetsi pasina chengetedzo inopa matambudziko akakosha kune zvigadzirwa zvemagetsi.
Zvisarudzo ndezvi:
Chengetedza fossil peaker zvirimwa zvichimhanya nekusingaperi
Chengetedza huwandu hukuru hwekugadzirwazve
Gamuchira kusagadzikana kwegridi uye kudzima
Shandisa grid-chikero chekuchengetedza
Sarudzo 4 haina kukwana. Mabhatiri ane mari, zvimhingamipinyi, uye njodzi. Asi ndiyo yega sarudzo inoenderana nekudzika decarbonization.
Hezvino izvo zvandakadzidza pakuongorora nzvimbo ino kwemakore mashanu: Mubvunzo hausi wekuti woshandisa grid-mabhatiri esikero. Sarudzo iyoyo yakatoitwa nefizikisi nehupfumi. Mubvunzo ndewokuti ndeapi mabhatiri, akaiswa kupi, uye anoshanda pasi pemhando dzipi dzebhizinesi.
Iyo tekinoroji yakagadzirira. Hupfumi huri nani. Kutumirwa kuri kukurumidza. Asi kubudirira kunoda kuwana chaiyo-chemistry yekushandisa, nzvimbo chaiyo yekuwana mari, optimization chaiyo yemamiriro emusika.
Iyo Net Zero Emissions ne2050 Scenario inoona zvese zviri zviviri kuendesa kwakakura kwezvinhu zvinogonekazve uye kuwedzera kukuru kwemagetsi kudiwa kubva mukuiswa magetsi. Giridhi-chikero chekuchengetedza, kunyanya mabhatiri, achave akakosha kuti ugadzirise kukanganiswa kwegetsi uye kubata musiyano weawa nemwaka mukubuda kwemagetsi anogona kuvandudzwa.
Icho hachisi chishuwo. Chinhu chinodiwa.
Mibvunzo Inowanzo bvunzwa
Grid{0}mabhatiri anogara kwenguva yakareba sei?
Lithium-mabhatiri eion mugridi-maapuro ekuchengetedza simba anowanzogara makore 10-15, asi masisitimu elead-asidhi anoshanda kwemakore mashanu-10. Asi "kugarisa" kunoda kusawirirana-kwesimba rebhatiri rinodzikira nekufamba kwenguva. Sitimu yemakore gumi-yakare inogona kuchengetedza 70-80% yezvekutanga. Tsvagiridzo yaJeff Dahn yakaratidza kuti 10,000-20,000 cycles dzinogoneka ne electrolyte tuning, kuderedza kukanganiswa kwezvakatipoteredza uye kufambisa motokari-kune-grid kuchengetedza. Pamashandisirwo egridi, izvi zvinoturikira ku15-20+ makore ekurarama pasi pekushanda kwakakwenenzverwa.
Sei mabhatiri asingakwanisi kuchengetedza mwaka?
Pure economics. Nemutengo we $200/kWh bhatiri, $200 trillion yemabhatiri-ka10 US GDP-inokwanisa kupa 1,000 TWh chete, ingangove masvondo matanhatu ekushandiswa kwesimba rekuUS rakachengetwa semafuta emakemikari. Kuchengetedza kwemwaka kunoda matekinoroji akasiyana: kupomba hydro, mweya wakadzvanywa, kana kuchengetedzwa kwemakemikari sehydrogen. Mabhatiri anokunda paawa kusvika kumazuva ese zvikero, kwete mwaka.
Mabhatiri egidhi akachengeteka mushure mezviitiko zveArizona neBeijing?
Njodzi yemoto ndeyechokwadi asi inogadziriswa nekugadzirwa kwakakodzera. Yakasimba chengetedzo mapuroteni uye matambudziko emitemo akabuda zvichitevera kupisa kwekutiza zviitiko zvinoburitsa utsi hune muchetura panguva yemoto. Kumisikidzwa kwemazuva ano kunosanganisira manejimendi akakwenenzverwa ekudziya kwemafuta, kupatsanurwa kwemasero, masisitimu ekudzima moto, uye-kutarisa nguva chaiyo. Alternative chemistries sesodium-ion nemabhatiri ekuyerera anopa maprofiles akachengeteka, izvo zviri kuita kuti kusimukira kwawo kukurumidze.
Chii chaicho chaicho-kufamba rwendo rwekuenda nemasisitimu aya?
Gridhi-mabhatiri esikero ane{1}}kufamba zvakanaka kwe70-90%, nelithium{4}}ion inosvika kuindasitiri-yepamusoro RTE ye90%+, lead{{10}inoyera asidhi inosvika 70%, mabhatiri anoyerera anenge 50{{17} uye dhizaini yakaderera-75% semhepo. Izvi zvinoreva kuti kana ukachengeta 100 MWh, unodzoka 70-90 MWh. Iyo 10-30% kurasikirwa mutengo chaiwo unofanirwa kuverengerwa mune zvehupfumi, asi lithium-ion's 90%+ kushanda zvakanaka ndosaka ichitonga kunyangwe mitengo yakakwira yekumberi.
Imari yakawanda sei yekuchengetedza iyo US inoda chaizvo?
Zero{{0}kabhoni remangwana panosvika 2050 rinoda 930 GW yenzvimbo yekuchengetera muUS, grid ichida 225-460 GW yenguva-yenguva yekuchengeta simba. Nezve mamiriro, iyo US parizvino ine inosvika makumi maviri nematanhatu GW inoshanda. Ndiko kuwedzera kwe35-40x kunodiwa mumakore makumi maviri nemashanu. Zvinogoneka-solar yakakura nekukurumidza-asi inoda kuchengetedzwa kwakasimba uye kuvandudza tekinoroji.
Mabhatiri ekare eEV anogona kushandiswazve kuchengetedza grid?
Hongu, uye zviri kutanga kuitika. Mabhatiri asingachasviki zviyero zvekushandiswa kweEV anowanzo chengetedza kusvika 80% yehuwandu hwawo hunogona kushandiswa. Nenhamba dzeEV dziri kuwedzera nekukurumidza, izvi zvinosvika terawatt-maawa esimba risingashandiswe rekuchengetedza simba rinogona kudzoserwa kune grid-zvikero zvekushandisa. Nekudaro, mabhatiri akaregeredzwa anoda maitiro ekugadzirisa anodhura kuti ashandiswe mumashandisirwo matsva, uye kushaikwa kwekumisikidza mukuyera mamiriro ehutano hwemabhatiri akashandiswa kunoramba kuri chipingamupinyi. Uhu hwehupfumi hunoenderana nemitengo mitsva yebhatiri-kana ikaramba ichidonha, kunatsiridza kunobva kwaita kushomeka.
Sei mimwe mishumo ichiyera kuchengetedza muMW panzvimbo yeMWh?
Mubvunzo mukuru unoratidza kuvhiringidzika kunyangwe pakati penyanzvi. Mune grid kugovera network, rinenge hapana simba rinochengetwa richienzaniswa nekushandiswa kwezuva nezuva; iyo shoma iyo inochengetwa yapera nguva iyo grid inomira kupihwa nemagetsi emagetsi. Chinokosha pakushanda isimba rinowanikwa rinogona kudhonzwa chero nguva kwenguva yakati rebei. Grid operators vane hanya nezve "unogona kupa 100 MW pandinoida?" kupfuura "maawa mangani unogona kuitsigira?" Zvose zvine basa, asi simba remagetsi ndiro rinodzivirira kudzima mumaminetsi ekutanga ekutanga ekuvhiringidza grid.
The Bottom Line
Gridhi-chiyero chekuchengetedza bhatiri hachisi chinhu chakanaka-kuva{2}}kuva neruzivo rwakamirira nguva yacho. Yatovepo, ichikura pa25-30% pagore, uye ichinyatso kugadzirisa mashandisiro anoita magetsi emagetsi.
Nzira yekuenda mberi haina kutwasuka. Zvinetso zvekuchengeteka zvinoramba zviripo. Kuremerwa kwenguva kunomanikidza maapplication. Kuwanikwa kwezvishandiso kunogadzira mabhodhoro. Kutengeswa kwemusika kunotyisidzira hupfumi sezvo kutumirwa kunowedzera.
Asi hapana chimwe chezvipingamupinyi izvi chinokanganisa chirevo chepakati: kushanduka kwesimba rinodzokororwa pachiyero chinoda kuchengetedzwa pamwero. Fizikisi inozvida. Economics inowedzera kuitsigira. Tekinoroji iri kusimukira kuti ikwanise.
Mubvunzo wezvishandiso, vagadziri vemitemo, uye vanogadzira hausi wekuti voisa grid-mabhatiri muchikero asi kuti oashandisa sei zvakakwana-kusarudza kemesitiri yepurogiramu yega yega, siting yeukoshi hukuru, uye kushanda nekunatsiridza kwakadzama kunoita kuti mari iwedzere paunenge uchigadzirisa kuderedzwa.
Kuchinja kwesimba kuri kuitika. Grid-mabhatiri esikero ari kuita kuti zvikwanisike.
