ʻenehana Li-Ion: ke hāʻule wikiwiki nei ke kumukūʻai ʻāpana ma mua o ka wānana

Aloha hou mai e nā hoa!

ʻO ka ʻatikala "ʻO ka manawa o ka lithium-ion UPS: kahi pōʻino ahi a i ʻole kahi palekana i ka wā e hiki mai ana?"Ua hoʻopaʻa mākou i ka pilikia o ke kumukūʻai i manaʻo ʻia o nā hopena Li-Ion (nā mea mālama, nā ʻāpana) ma nā ʻōlelo kikoʻī - $/kWh. A laila ʻo ka wānana no 2020 he $200/kWh. I kēia manawa, e like me ka mea i ʻike ʻia mai ka CDPV, ua hāʻule ke kumukūʻai o ka lithium ma lalo o $ 150 a ua wānana ʻia kahi hāʻule wikiwiki ma lalo o $ 100/kWh (e like me ka Forbes). He aha kēia hoʻololi, e nīnau ʻoe? ʻO ka mea mua, ke hoʻemi ʻia nei ka ʻokoʻa ma waena o ke kumukūʻai o nā ʻenehana maʻamau a me nā ʻenehana hoʻohiki, a me nā hopena e pili ana iā lākou. E ho'āʻo kāua e helu ma ke kumu o ka hihia o kēlā mokumoku Kepani like me nā ʻona Li-Ion.

ʻIkepili mua

Lawe mākou i ka ʻikepili mua:

• ka wānana kumukūʻai o 200 $ / kWh mai kā mākou ʻatikala e pili ana i ka palekana ahi o ka lithium
• ka wanana kumukūʻai o 300 $/kWh mai kā mākou ʻatikala 2018 “UPS a me nā pūʻali pākahi...”
• ʻO ka ʻokoʻa kumukūʻai i manaʻo ʻia ma waena o VRLA a me Li-Ion solutions he 1,5-2 mau manawa, i lawe ʻia mai kā mākou ʻatikala 2018 e pili ana i ke ahi o ka lithium.

I kēia manawa e helu kāua

1. Ua makaʻala loa ka emi ʻana o ke kumukūʻai o nā kaʻa; ʻoi aku ka wikiwiki o ka emi maoli
2. ʻO ka mea hoʻoikaika ma hope o ka hāʻule ʻana o ke kumukūʻai o nā ʻoihana ʻenehana me ka hoʻohana ʻana i nā pākahi lithium-ion he mau kaʻa uila: ke piʻi nei ka nui o ka ikehu i loko o ka pākaukau, ke hoʻololi nei nā hoʻolālā, a ke ulu wikiwiki nei ka hana. Hiki iā ʻoe ke heluhelu hou aku ma "Loaʻa ka mea kākau ma ʻaneʻi"
3. ʻO 17 MWh ka mana pākaukau i manaʻo ʻia o ka submarine Iapana; lawe mākou i ke kumu kūʻai o ka lithium no 2017 i ka nui o $300/kWh. Loaʻa iā mākou he 5,1 miliona kālā.
4. Ma muli o ke kumukūʻai maoli mai ka CDPV, ʻo ka hāʻule ʻana ma kahi o 2% ma mua o 30 mau makahiki. ʻAʻole hewa huh? Manaʻo wau i ke kūkulu ʻana i kēlā mau waʻa, pono e hoʻouka iā ia me nā pihi Li-Ion i ka manawa hope loa, ma mua o ka hele ʻana i nā hoʻāʻo kai.
5. Hiki ke manaʻo ʻia no ka hoʻonā ʻenehana ma nā pā lithium, ʻo ka hāʻule ʻana o ke kumukūʻai, heluhelu i ka hoʻohālikelike ʻana i ke kumukūʻai me nā ʻano pahu pahu lead-acid, ʻoi aku ka wikiwiki ma mua o ka mea i manaʻo ʻia. Ma kahi ʻatikala 2018, ʻo ka ʻokoʻa i manaʻo ʻia ma waena o kahi UPS ma nā pā lithium he 1,5-2 mau manawa ʻoi aku ka maikaʻi ma mua o kahi UPS maʻamau. I kēia manawa, ʻoi aku ka liʻiliʻi o kēia āpau ...

… e hoʻomau ʻia…
