Dịka akụkọ mgbasa ozi si mba ofesi si kwuo, Ngalaba Ike nke US (DOE) na-eme atụmatụ inye ndị mmepe ihe mkpali na ego ruru nde dọla iri atọ maka itinye usoro nchekwa ike, n'ihi na ha na-atụ anya ibelata ọnụ ahịa nke itinye usoro nchekwa ike.
A ga-ekewa ego a, nke Ụlọ Ọrụ Ọkụ eletrik nke DOE (OE) na-achịkwa, ụzọ abụọ hà nhata nke $15 nde nke ọ bụla. Otu n'ime ego a ga-akwado nnyocha iji melite ntụkwasị obi nke sistemụ nchekwa ike ogologo oge (LDES), nke nwere ike inye ike ruo opekata mpe awa iri.

Na Machị nke afọ a, mmemme ahụ kwere nkwa inye $2 nde ego nye ụlọ nyocha mba isii nke Ngalaba Ike nke US iji nyere ụlọ ọrụ nyocha ndị a aka ime nnyocha, ego ọhụrụ nke $15 nde nwere ike inye aka mee ka nnyocha dị ngwa na sistemụ nchekwa ike batrị.
Ọkara nke ọzọ nke ego DOE ga-akwado ụfọdụ sistemụ nchekwa ike nke dị na mmalite nke nyocha na mmepe, nke na-adịghịkwa njikere maka mmejuputa azụmahịa.
Mee ka ntinye nke sistemụ nchekwa ike dịkwuo ngwa ngwa
Gene Rodrigues, Osote Odeakwụkwọ maka Ọkụ eletrik na Ngalaba Ike nke US, kwuru, sị: "Ịnweta ego ndị a ga-eme ka usoro nchekwa ike dịkwuo ngwa ngwa n'ọdịnihu ma nye azịza dị ọnụ ala maka igbo mkpa ọkụ eletrik nke ndị ahịa. Nke a bụ nsonaazụ nke ọrụ siri ike nke ụlọ ọrụ nchekwa ike." , ụlọ ọrụ ahụ nọ n'ihu n'ịkwalite mmepe nke nchekwa ike ogologo oge kachasị ọhụrụ.
Ọ bụ ezie na Ngalaba Ike nke US ekwughị ndị mmepe ma ọ bụ ọrụ nchekwa ike ga-enweta ego ahụ, atụmatụ ndị a ga-arụ ọrụ iji mezuo ebumnuche 2030 nke Energy Storage Grand Challenge (ESGC) setịpụrụ, nke gụnyere ụfọdụ Target.
E hiwere ESGC na Disemba 2020. Ebumnuche nke ihe ịma aka a bụ ibelata ọnụ ahịa nchekwa ike maka sistemụ nchekwa ike ogologo oge site na 90% n'etiti 2020 na 2030, na-eme ka ọnụ ahịa ọkụ eletrik ha daa ruo $0.05/kWh. Ebumnuche ya bụ ibelata ọnụ ahịa mmepụta nke ngwugwu batrị EV nke kilomita 300 site na 44% n'ime oge ahụ, na-eme ka ọnụ ahịa ya daa ruo $80/kWh.
E jirila ego sitere n'aka ESGC kwado ọtụtụ ọrụ nchekwa ike, gụnyere "Grid Energy Storage Launchpad" nke Pacific Northwest National Laboratory (PNNL) na-ewu na $75 nde ego gọọmentị nyere. Ego ọhụrụ a ga-aga maka ọrụ nyocha na mmepe ndị yiri ya.
ESGC enyekwala ụlọ ọrụ anọ, Largo Clean Energy, TreadStone Technologies, OTORO Energy na Quino Energy, nde dọla iri na asaa na itoolu, iji mepụta usoro nyocha na mmepụta ọhụrụ maka nchekwa ike.
Usoro mmepe nke ụlọ ọrụ nchekwa ike na United States
DOE kwupụtara ohere ọhụrụ ndị a maka ego na Nzukọ ESGC na Atlanta. DOE kwukwara na Ụlọ Nyocha Mba Pacific Northwest na Ụlọ Nyocha Mba Argonne ga-arụ ọrụ dị ka ndị nhazi ọrụ ESGC maka afọ abụọ na-abịa. Ụlọ Ọrụ Ọkụ Eletriki (OE) nke DOE na Ụlọ Ọrụ Ọkụ Ike na Ike Mmeghari ohuru nke DOE ga-enye ego $300,000 iji kpuchie ọnụ ahịa mmemme ESGC ruo na njedebe nke afọ ego 2024.
Akụkụ ụlọ ọrụ mmepụta ihe zuru ụwa ọnụ anabatala ego ọhụrụ a nke ọma, Andrew Green, onye isi nchịkwa nke International Zinc Association (IZA), kwuru na obi dị ya ụtọ maka akụkọ ahụ.
"Ọgbakọ Zinc nke Mba Nile nwere obi ụtọ ịhụ Ngalaba Ike nke US na-ekwupụta nnukwu itinye ego ọhụrụ na nchekwa ike," Green kwuru, na-ekwupụta mmụba mmasị na zinc dị ka akụkụ nke sistemụ nchekwa batrị. O kwuru, sị, "Obi dị anyị ụtọ maka ohere ndị batrị zinc na-eweta na ụlọ ọrụ ahụ. Anyị na-atụ anya ịrụkọ ọrụ ọnụ iji dozie atụmatụ ọhụrụ ndị a site na atụmatụ batrị zinc."
Akụkọ a na-esochi mmụba dị egwu n'ikike arụnyere na sistemụ nchekwa batrị e tinyere na United States n'afọ ndị na-adịbeghị anya. Dịka data nke US Energy Information Administration wepụtara si kwuo, ike arụnyere na nnukwu sistemụ nchekwa ike batrị na United States amụbaala site na 149.6MW na 2012 ruo 8.8GW na 2022. Ọsọ uto na-arịkwa elu nke ukwuu, ebe 4.9GW nke sistemụ nchekwa ike e tinyere na 2022 fọrọ nke nta ka ọ bụrụ okpukpu abụọ karịa nke afọ gara aga.
Ego gọọmentị US nwere ike ịdị oke mkpa iji mezuo ebumnuche nchekwa ike ya dị oke mkpa, ma n'ihe gbasara ịbawanye ikike arụnyere na sistemụ nchekwa ike na United States na ịmepụta teknụzụ nchekwa ike ogologo oge. N'ọnwa Nọvemba gara aga, Ngalaba Ike nke US kwupụtara kpọmkwem ego ruru nde dọla 350 maka ọrụ nchekwa ike ogologo oge, na-achọ ịgba ume ka ihe ọhụrụ dị n'ọhịa a.
