Hoʻohana ʻia nā kaʻa ikehu hou e ka -ʻaila hinu, a ʻokoʻa ko lākou mau loina hana ma muli o ke ʻano o ke kumu mana. No ka laʻana, hoʻohana ka kaʻa uila maʻemaʻe i hoʻokahi pākaukau ma ke ʻano he kumu mana mālama ikehu. Hāʻawi kēia pākaukau i ka ikehu uila i ke kaʻa uila, nāna e hoʻokele i ke kaʻa a pēlā e hoʻolalelale ai i ke kaʻa. ʻO ke kumu hana o nā kaʻa ikehu hou:
1. Ho'ohana 'ia nā ka'a ikehu hou e ka -hua'aila 'ole. Ke hana nei nā kaʻa maʻamau ma ka hoʻololi ʻana i ka ikehu wela i ka ikehu mechanical ma o ke kaʻina hoʻomau o ka lawe ʻana, ka hoʻoemi, ka hana mana, a me ka pau. Kapa ʻia kēlā me kēia kaʻina hana he pōʻaiapili mana. Eia naʻe, ʻokoʻa nā loina hana o nā kaʻa ikehu hou ma muli o ke ʻano o ke kumu mana.
2. Ua like nā loina hana o nā kaʻa hybrid a me nā kaʻa ʻenekini hydrogen me nā kaʻa maʻamau.
3. ʻO nā kaʻa uila kaʻa he mau kaʻa e hoʻohana ana i ka uila i hana ʻia e ka hopena electrochemical i loko o kahi pahu wahie, i hana ʻia e ka hydrogen a me ka oxygen i ka lewa ma lalo o ka hana a ka catalyst. He ʻano kaʻa uila maʻemaʻe ke ʻano o nā kaʻa uila uila, ʻokoʻa ma ke kumu hana o ka pā uila. ʻO ka ʻōlelo maʻamau, hoʻololi ʻia ka ikehu kemika i ka ikehu uila ma o ka hopena electrochemical. ʻO ka mea hoʻohaʻahaʻa i koi ʻia no kēia hopena electrochemical maʻamau, ʻo ia ka hydrogen, a ʻo ka mea hoʻohenehene he oxygen maʻamau. No laila, ua hoʻohana mua ʻia nā kaʻa uila i hoʻohana mua ʻia i ka wahie hydrogen. Hiki ke mālama ʻia ka hydrogen ma nā ʻano like ʻole, e like me ka hydrogen liquefied, hydrogen compressed, a i ʻole ka waiho ʻana i ka hydride metala.
4. ʻO ke kaʻa uila maʻemaʻe he kaʻa ia e hoʻohana ana i hoʻokahi pākahi ma ke ʻano he kumu mana e mālama ai i ka ikehu. Hāʻawi kēia pākaukau i ka ikehu uila i kahi kaʻa uila, nāna e hoʻokele i ke kaʻa a pēlā e hoʻolalelale ai i ke kaʻa.
5. 'O nā ka'a ikehu hou 'ē a'e ka mea e ho'ohana ana i nā mea ho'opa'a ikehu ki'eki'e e like me nā supercapacitors a me nā huila lele. I kēia manawa ma koʻu ʻāina, pili nui nā kaʻa ikehu hou i nā kaʻa uwila maʻemaʻe, -kaʻa uwila lōʻihi, hoʻopili-i nā kaʻa hybrid, a me nā kaʻa uila. Hoʻokaʻawale ʻia nā kaʻa hybrid maʻamau ma ke ʻano he kaʻa mālama ikehu-.
6. Ma ke ao holoʻokoʻa, loaʻa nā kumu mana kaʻa ikehu hou i nā ʻeke lithium-ion, nickel-metal hydride batteries, nā pahu wahie, lead-acid batteries, me nā supercapacitors i hoʻohana pinepine ʻia ma ke ʻano he kumu mana kōkua.
