ʻEhia ka nui o ke kumukūʻai mālama ikehu lithium-ion i hiki iā mākou ke hoʻohana i ka ikehu hou? [MĀNĀWAI]

Ua helu nā kānaka ʻepekema mai ka Massachusetts Institute of Technology i nā pae e pono ai e hōʻiliʻili i ka ikehu i mea e pono ai ke hoʻololi i nā mea kanu kuʻuna me nā kumu ikehu hou. ʻIke ʻia me ka hoʻololi piha ʻana i ka ikehu hou, pono e hoʻololi nā kumukūʻai mai 5 a 20 kālā no kWh.

ʻOi aku ke kumu kūʻai o nā pila o kēia lā ma mua o $100 no ka hola kilowatt.

Aia nā lono ua hiki i nā mea hana ke hoʻemi i ka $ 100- $ 120 no ka kilowatt-hola o nā cell lithium-ion, ʻoi aku ia ma mua o $ 6 (mai ka PLN 23-60) no ke kelepona i kahi pākahi kaʻa awelika. Ke manaʻo ʻia nei ke kumu kūʻai ʻana o nā kelepona lithium iron phosphate CATL ma lalo o $1/kWh.

Eia naʻe, e like me ka poʻe noiʻi ma Massachusetts Institute of Technology, ʻoi aku ka nui o kēia. Inā makemake mākou e hoʻohana wale i ka ikehu hou a mālama i ka ikehu i loko o nā pā lithium-ion, pono ia e haʻalele. a hiki i ka 10-20 $ / kWh ke hoʻololi i kahi mea kanu nuklea. No nā mea kanu kinoea i puhi ʻia i ke kinoea - helu ʻia e pili ana i ʻAmelika Hui Pū ʻIa, ʻo ia ka 4th nui loa o ka honua i hana ʻia i ke kinoea maoli - ʻo ke kumu kūʻai o ka pā lithium-ion pono e emi iho - he $5 wale nō no kWh.

Akā, eia kahi ʻike: manaʻo nā helu ma luna ka mea maʻamau ka hoʻololi ʻana i nā mea kanu mana i wehewehe ʻia me RES, ʻo ia hoʻi, nā mea mālama ikehu i lawa no ka hoʻokō ʻana i nā pono i ka wā lōʻihi o ka hāmau a me ka maikaʻi ʻole o ka lā. Inā ʻike ʻia ua hoʻopuka ʻo RES i "wale nō" 95 pakeneka o ka ikehu, ʻO ka mālama ʻana i ka ikehu ka manaʻo hoʻokele waiwai i $150/kWh!

Ua kokoke mākou i hiki i ke kiʻekiʻe o $150 no ka kilowatt-hola. ʻO ka pilikia, ʻaʻole lawa nā hale hana pākaukau lithium-ion ma ka honua no ka hoʻokō ʻana i nā pono o nā mea hana kaʻa, koe wale nō nā hale kūʻai ikehu nunui. He aha nā koho ʻē aʻe? He mea maʻalahi ka hana ʻana o nā pākaʻi kahe o Vanadium, akā he kumukūʻai ($100/kWh). He ʻuʻuku nā pahu hoʻopaʻa a i ʻole nā ea i hoʻopaʻa ʻia ($20/kWh) akā makemake i nā wahi nui a me nā kūlana ʻāina kūpono. ʻO ke koena o nā ʻenehana haʻahaʻa aia wale nō ma ke kahua o ka noiʻi a me ka hoʻomohala ʻana - manaʻo mākou i kahi holomua ma mua o 5 mau makahiki.

Pono e heluhelu: Pehea ke kumukūʻai o nā mea mālama ikehu e pono ai e hoʻololi i nā pono hana i ka 100 pakeneka ikehu hou?

Kiʻi hoʻolauna: mālama ʻia ka ikehu Tesla ma ka ʻaoʻao o ka māla lā Tesla.
