Msika wosungira mphamvu ku US uli ndi ukadaulo wolemera komanso wosiyanasiyana, ndipo ukadaulo wosiyanasiyana umagwira ntchito bwino m'njira zosiyanasiyana, zomwe zikuyendetsa chitukuko cha makampani osungira mphamvu.
Ukadaulo wa Batri wa Lithium-ion
Mabatire a lithiamu-ion akhala ukadaulo wodziwika bwino pamsika wosungira mphamvu ku US chifukwa cha kuchuluka kwa mphamvu zawo, moyo wautali komanso nthawi yoyankha mwachangu, zomwe zimapangitsa kuti pakhale mphamvu zoposa 80% yosungira mphamvu zomwe zimagwiritsidwa ntchito kwambiri. Ukadaulo wake ndi wakale kwambiri ndipo umagwiritsidwa ntchito kwambiri, kuyambira ku malo akuluakulu osungira mphamvu mpaka makina ang'onoang'ono osungira mphamvu omwe amagawidwa. Mwachitsanzo, m'mapulojekiti ena akuluakulu osungira mphamvu ku California, makina osungira mphamvu a lithiamu-ion amakhala ndi vuto lolinganiza kupezeka ndi kufunikira kwa gridi, ndikugwiritsa ntchito mphamvu zatsopano. Komabe, mabatire a lithiamu-ion alinso ndi zofooka zina, monga moyo wafupikitsa wa batri pa kutentha kwambiri, kuyaka kwa electrolyte ndi mavuto ena, zomwe zimalepheretsa kugwiritsa ntchito kwawo m'zochitika zina zapadera.
Ukadaulo wa Mabatire Oyenda Madzi
Ndi mphamvu zambiri zosungira mphamvu komanso nthawi yayitali yogwiritsira ntchito mphamvu, batire yamadzimadzi ndi yoyenera kwambiri posungira mphamvu zambiri, monga malo opangira magetsi akuluakulu a photovoltaic ndi malo opangira mphepo. Imagwira ntchito yosungira mphamvu zamagetsi ndi kutulutsa mphamvu kudzera mu redox reaction ya ma ayoni mu electrolyte, ndipo ili ndi ubwino wotetezeka kwambiri komanso kutulutsa mphamvu mozama. Ku US, mapulojekiti osungira mphamvu m'malo ena ayamba kugwiritsa ntchito ukadaulo wa batire yamadzimadzi kuti athetse vuto la nthawi yopangira mphamvu zatsopano ndikuwonjezera kukhazikika kwa dongosolo lamagetsi.
Ukadaulo wa batri wolimba
Mabatire olimba amaonedwa ngati njira yofunika kwambiri yopititsira patsogolo ukadaulo wosungira mphamvu wa m'badwo wotsatira, ndipo akuyembekezeka kuthetsa mavuto achitetezo a mabatire a lithiamu-ion pomwe akukweza kuchuluka kwa mphamvu ndi magwiridwe antchito a chaji/kutulutsa. Mosiyana ndi mabatire achikhalidwe a lithiamu-ion omwe amagwiritsa ntchito ma electrolyte amadzimadzi, mabatire olimba amagwiritsa ntchito ma electrolyte olimba, omwe amachepetsa chiopsezo cha kutentha kwa batire ndikukweza chitetezo ndi kukhazikika kwa batire. Pakadali pano, mabungwe ofufuza aku US ndi mabizinesi omwe ali mu kafukufuku ndi chitukuko cha ukadaulo wa batire olimba adayika ndalama zambiri, ngakhale kuti sanagwiritse ntchito kwambiri malonda, koma afika pamlingo wofunikira, tsogolo likuyembekezeka kukhala ndi malo pamsika wosungira mphamvu.
Ukadaulo wa Super-capacitor
Super-capacitor ili ndi mphamvu zambiri, kuthamanga kwachangu komanso kuthamanga kwa mphamvu, nthawi yayitali yogwira ntchito, ndi zina zotero. Ndi yoyenera pazochitika zomwe zimafuna mphamvu zambiri komanso nthawi zambiri zolipiritsa ndi kutulutsa mphamvu, monga njira yobwezeretsa mphamvu m'munda wa mayendedwe komanso kayendetsedwe ka mphamvu mwachangu. Ku US, ukadaulo wa super-capacitor umagwiritsidwa ntchito m'mapulogalamu ena osungira mphamvu, kuphatikiza ukadaulo wina wosungira mphamvu kuti ugwire bwino ntchito yamagetsi.
