Sekureva kwemishumo yenhau dzekunze, Dhipatimendi reSimba reUS (DOE) rinoronga kupa vanogadzira mapurani mari inosvika mamiriyoni makumi matatu emadhora ekukurudzira uye mari yekuisa masisitimu ekuchengetera simba, nekuti rinotarisira kuderedza zvakanyanya mari yekushandisa masisitimu ekuchengetera simba.
Mari iyi, inotungamirwa neDOE's Office of Electricity (OE), ichakamurwa kuita mari mbiri dzakaenzana dzemadhora mamiriyoni gumi nemashanu imwe neimwe. Imwe yemari iyi ichatsigira tsvakiridzo yekuvandudza kuvimbika kwemasisitimu ekuchengetera simba kwenguva refu (LDES), ayo anogona kupa simba kwemaawa gumi. Imwe mari ichapa mari yeUS Department of Energy's Office of Electricity (OE) Rapid Operational Demonstration Program, iyo yakagadzirirwa kukurumidza kubhadhara kushandiswa kwenzvimbo itsva dzekuchengetera simba.
MunaKurume wegore rino, chirongwa ichi chakavimbisa kupa mari inosvika mamiriyoni maviri emadhora kumarabhoritari matanhatu eUS Department of Energy kuti abatsire masangano aya ekutsvagisa kuita tsvakiridzo, uye mari itsva inosvika mamiriyoni gumi nemashanu emadhora inogona kubatsira kukurumidzisa tsvakiridzo pamasisitimu ekuchengetedza simba remabhatiri.
Imwe hafu yemari yeDOE ichatsigira mamwe masisitimu ekuchengetedza simba ari muchikamu chekutanga chekutsvagisa nekuvandudza, uye asati agadzirira kushandiswa mubhizinesi.
Kurumidza kushandiswa kwemasisitimu ekuchengetedza simba
Gene Rodrigues, Mutevedzeri weMunyori weMagetsi kuDhipatimendi reSimba reUS, akati: "Kuwanikwa kwemari iyi kuchakurumidzisa kushandiswa kwemasisitimu ekuchengetera magetsi mune ramangwana uye kuchapa mhinduro dzinodhura dzekuzadzisa zvinodiwa nevatengi zvemagetsi. Izvi zvinokonzerwa nekushanda nesimba kweindasitiri yekuchengetera magetsi." , indasitiri iyi iri pamberi mukusimudzira kuvandudzwa kwekuchengetera magetsi kwenguva refu kwenguva refu.
Kunyange hazvo Dhipatimendi reSimba reUS risina kuzivisa kuti ndevapi vanogadzira kana mapurojekiti ekuchengetera simba achawana mari iyi, zvirongwa izvi zvichashanda kuzadzisa zvinangwa zvegore ra2030 zvakatarwa neEnergy Storage Grand Challenge (ESGC), iyo inosanganisira zvimwe zvinangwa.
ESGC yakatangwa muna Zvita 2020. Chinangwa chedambudziko iri ndechekuderedza mutengo wekuchengetedza simba wemasisitimu ekuchengetera simba kwenguva refu ne90% pakati pa2020 na2030, zvichideredza mitengo yemagetsi kusvika pa$0.05/kWh. Chinangwa chayo ndechekuderedza mutengo wekugadzira bhatiri reEV remakiromita mazana matatu ne44% munguva iyoyo, zvichideredza mutengo wayo kusvika pa$80/kWh.
Mari inobva kuESGC yakashandiswa kutsigira mapurojekiti akawanda ekuchengetera magetsi, kusanganisira "Grid Energy Storage Launchpad" iri kuvakwa nePacific Northwest National Laboratory (PNNL) nemari inosvika mamiriyoni makumi manomwe nemashanu emadhora kubva kuhurumende. Mari yazvino ichashandiswawo kumapurojekiti ekutsvaga nekusimudzira ane hunyanzvi hwakafanana.
ESGC yakapawo mari inosvika $17.9 miriyoni kumakambani mana, Largo Clean Energy, TreadStone Technologies, OTORO Energy naQuino Energy, kuti vagadzire nzira itsva dzekutsvagisa nekugadzira magetsi ekuchengetedza magetsi.
Kufambira mberi kweindasitiri yekuchengetedza simba muUnited States
DOE yakazivisa mikana mitsva iyi yekutsigira mari pamusangano weESGC muAtlanta. DOE yakataurawo kuti Pacific Northwest National Laboratory neArgonne National Laboratory zvichashanda sevarongi vemapurojekiti eESGC kwemakore maviri anotevera. Hofisi yeMagetsi yeDOE (OE) neHofisi yeEnergy Efficiency neRenewable Energy yeDOE imwe neimwe ichapa $300,000 mumari yekubhadhara mari yechirongwa cheESGC kusvika pakupera kwegore remari ra2024.
Mari itsva iyi yakagamuchirwa zvakanaka nemakambani epasi rose anotengesa zvinhu, Andrew Green, mukuru weInternational Zinc Association (IZA), achiti ari kufara nemashoko aya.
"Sangano reInternational Zinc Association rinofara kuona Dhipatimendi reSimba reUS richizivisa mari itsva mukuchengetedza simba," akadaro Green, achitaura nezvekufarira kuri kukura kwe zinc sechikamu chehurongwa hwekuchengetedza mabhatiri. Akati, "Tinofara nemikana inounzwa nemabhatiri e zinc muindasitiri. Tinotarisira kushanda pamwe chete kugadzirisa zvirongwa zvitsva izvi kuburikidza nechirongwa chemabhatiri e zinc."
Mashoko aya anotevera kuwedzera kukuru kwesimba remagetsi ekuchengetedza mabhatiri akashandiswa muUnited States mumakore achangopfuura. Sekureva kwedata rakaburitswa neUS Energy Information Administration, simba remagetsi ekuchengetedza mabhatiri akashandiswa rakaiswa muUnited States rakawedzera kubva pa149.6MW muna 2012 kusvika pa8.8GW muna 2022. Kukura kuri kuwedzerawo zvakanyanya, ne4.9GW yemagetsi akashandiswa muna 2022 yakapetwa kaviri kubva mugore rapfuura.
Mari yehurumende yeUS ingangove yakakosha pakuzadzisa zvinangwa zvayo zvekuisa simba, zvese maererano nekuwedzera kugona kwekuisa masisitimu ekuchengetera simba muUnited States uye kugadzira matekinoroji ekuchengetera simba kwenguva refu. Muna Mbudzi wapfuura, Dhipatimendi reSimba reUS rakazivisa zvakananga $350 miriyoni mukutsigira mapurojekiti ekuchengetera simba kwenguva refu, nechinangwa chekukurudzira hunyanzvi muchikamu ichi.
