ʻO ka mālama ʻana i ka ikehu Vanadium – 1

ʻO ka kaulana o ka ʻoihana ikehu hou e hana i ka lithium carbonate, ka mea maka o nā pā lithium, kahi "ʻaila keʻokeʻo" I loko o ka ʻenehana ʻenehana, ʻo kahi ala ʻē aʻe "vanadium electricity" e mohala mālie nei.

I ka waena o Feberuari, "ka papahana aupuni o 200MW / 800mwh Dalian kahe wai kahe mana waihona ikehu a me ka peak shaving mana mana" hai mai la i ka mana o ke kukulu ana i ka papahana nui. ʻO ke kahua mana ka papahana hōʻikeʻike aupuni nui 100MW mua o ka mālama ʻana i ka ikehu electrochemical ma Kina. E lilo ana ia i ka nui loa o ka vanadium flow battery energy storage project ma ka honua. Manaʻo ʻia e hoʻopau ʻia ke kōmike pili pūnaewele i Iune o kēia makahiki.

He aha ka manaʻo o ka papahana hoʻopaʻa ikehu pilahi nui loa o ka honua? Loaʻa i ka mana mana ka mana mālama mālama o 400mwh, e like me 400000 kwh E like me ka awelika o ka mana o ka ʻohana o 200 degere, hiki iā ia ke hāʻawi aku ma mua o 2000 mau ʻohana no hoʻokahi mahina. Ma ke ʻano he wahi mana shaving peak, hiki iā ia ke hoʻohaʻahaʻa i ke kaomi ʻana o ka mana o ka mana kūloko a hoʻopau i ka koi mana i ka manawa.

ʻO ka mālama ʻana i ka ikehu ke kumu o ka hoʻololi ʻoihana ikehu hou I ka pōʻaiapili o ka "carbon double", e emi ana ka nui o ka hoʻohana ʻana i ka mana lanahu, akā ʻo ka ikehu hou e like me ka makani makani a me ka mana o ka lā ke kū nei i nā ʻano o ka discontinuity, instability a me uncontrollability no ka manawa lōʻihi. No laila, pehea e mālama maikaʻi ai i kēia mau kumu ikehu i lilo i kī no ka hoʻohana ʻana i ka uila ʻōmaʻomaʻo.

Mai ka hiʻohiʻona o ka hoʻonohonoho ʻana i ka ikehu, ke nānā mau nei ʻo Kina i ka pauma a me ka mālama ʻana i ka mana i kēia manawa - i ka wā e haʻahaʻa ai ka hoʻohana ʻana i ka mana, e puhi ʻia ka wai mai ka waihona haʻahaʻa a i ka waihona luna ma o ka uila, a laila hoʻokuʻu ʻia ka wai no ka hana mana ma ka piko. o ka hoohana mana I ka makahiki 2020, ʻo ka hapa o ka mālama ʻana i ka pumped ma Kina e hiki i kahi kokoke i 90%, a ʻo ka lua ka mālama ʻana i ka ikehu electrochemical, me ka pā lithium-ion, ka pākaukau lead-acid, ka wai kahe wai a me nā ʻenehana ʻē aʻe.
