Kodi mphamvu yosungira mphamvu ya lithiamu-ion iyenera ndalama zingati kuti tingogwiritsa ntchito mphamvu zowonjezera? [NKHANI]

Asayansi ku Massachusetts Institute of Technology awerengera kuti mphamvu ikuyenera kusungidwa iti kuti isinthe mopindulitsa mbewu zanthawi zonse zamagetsi ndi magwero ongowonjezera mphamvu. Zikuoneka kuti ndi kusintha kwathunthu ku mphamvu zongowonjezwdwa, mitengo iyenera kusinthasintha kuchokera pa $ 5 mpaka $ 20 pa kWh.

Masiku ano mabatire amawononga $ 100 pa ola la kilowatt.

Pali kale mphekesera kuti opanga atha kuchepetsa mlingo wa madola 100-120 pa kilowatt-ola ya maselo a lithiamu-ion, omwe ndi oposa 6 madola (kuchokera ku 23 zloty) pa selo kupita ku batri ya galimoto. Maselo aku China a CATL lithiamu iron phosphate akuyembekezeka kuwononga ndalama zosakwana $ 60 pa kWh.

Komabe, malinga ndi ofufuza a Massachusetts Institute of Technology, izi zikadali zochuluka. Ngati tikufuna kugwiritsa ntchito mphamvu zongowonjezedwanso ndikusunga mphamvu zochulukirapo m'mabatire a lithiamu-ion, zingakhale zofunikira kusiya. mpaka 10-20 $ / kWh posintha malo opangira magetsi a nyukiliya. Kwa magetsi opangira mpweya - kuwerengera zochokera ku United States, yomwe ili dziko la 4 padziko lonse lapansi lagasi - mtengo wa batri ya lithiamu-ion uyenera kukhala wotsika kwambiri - $ 5 okha pa kWh.

Koma chidwi ndi ichi: ndalama zomwe zili pamwambazi zimaganiziridwa wamba m'malo mwa magetsi omwe akufotokozedwa ndi magwero a mphamvu zongowonjezwdwa, ndiko kuti, malo osungira mphamvu zokwanira kuti akwaniritse zosowa za nthawi yayitali ya chete komanso kuwala kwa dzuwa. Ngati zongowonjezwdwa zapezeka kuti zikupanga "zokha" 95 peresenti ya mphamvu, kusungirako mphamvu kumamveka bwino pazachuma kale pa $ 150 / kWh!

Tafika pafupifupi pamlingo wa $150 pa kilowatt-ola. Vuto ndiloti kulibe mafakitale okwanira a lithiamu-ion batire padziko lapansi kuti akwaniritse zosowa za opanga magalimoto, osasiyanso masitolo akuluakulu amagetsi. Kodi zinanso ziti? Mabatire otuluka a Vanadium ndi osavuta kupanga, koma okwera mtengo ($100/kWh). Matanki osungira kapena mpweya woponderezedwa ndi wotchipa ($20/kWh) koma amafunikira madera akuluakulu ndi malo oyenera. Matekinoloje ena otsika mtengo ali pagawo la kafukufuku ndi chitukuko - tikuyembekeza kupambana posachedwa kuposa zaka 5.

Zoyenera kuwerenga: Kodi kusungirako magetsi kumayenera kukhala kotsika mtengo bwanji kuti zida zisinthe kukhala mphamvu zongowonjezedwanso 100 peresenti?

Chithunzi chotsegulira: Tesla yosungirako mphamvu pafupi ndi Tesla solar farm.
