Nā Kaʻa Hui Pū ʻIa Hydrogen: Maʻemaʻe a Maikaʻi ka Kaʻa ʻana i ka wā e hiki mai ana

Me ka hoʻonui nui ʻana o ka nānā ʻana i ka mālama ʻana i ke kaiapuni a me ka ikehu hoʻomau, ua ʻike nui ʻia nā kaʻa kaʻa hydrogen wahie ma ke ʻano he ala maʻemaʻe a maikaʻi hoʻi o ka halihali. E wehewehe kēia ʻatikala i ka hana ʻana o nā kaʻa kaʻa hydrogen fuel cell, nā pōmaikaʻi a me nā pilikia, a e ʻimi i ko lākou hiki i ka wā e hiki mai ana.

He kaʻa kaʻa kaʻa hydrogen e hoʻohana i ka hydrogen i wahie a hoʻohua i ka uila ma o ka pahu hau hydrogen e hoʻokele ai i kahi kaʻa uila. Hoʻokumu ʻia kāna kumu hana ma luna o ka hopena kemika o ka hydrogen a me ka oxygen i loko o kahi pahu wahie hydrogen e hana ai i ka uila a me ka mahu wai. Hoʻohana ʻia kēia ikehu uila no ka hoʻoikaika ʻana i kahi kaʻa uila, e hoʻolalelale i ke kaʻa i mua. Hoʻohālikelike ʻia me nā kaʻa wahie maʻamau, ʻo ke kinoea hoʻopau o nā kaʻa hydrogen wahie he mahu wai wale nō, me ka ʻole o nā hoʻokuʻu kinoea ʻino, a ʻaʻohe pollution i ke kaiapuni.

He nui nā pōmaika'i o nā ka'a ka'a wahie hydrogen. ʻO ka mea mua, pili lākou i ke kaiapuni ma muli o kā lākou mau hiʻohiʻona zero-emission. No ka mea, ʻo ka hua wale nō o ka puhi ʻana i ka hydrogen he mahu wai, hiki i nā kaʻa hydrogen wahie ke hōʻemi nui i ka pollution o ka ea a me ka hoʻokuʻu ʻana i ke kinoea ʻōmaʻomaʻo, e kōkua ana i ka hoʻomaikaʻi ʻana i ka maikaʻi o ka ea a me ka hoʻēmi ʻana i ka hoʻololi ʻana i ke aniau. ʻO ka lua, ʻo nā kaʻa hydrogen wahie he kiʻekiʻe ka ikehu a me ka lōʻihi o ka holo ʻana. Ke hoʻohālikelike ʻia me ka pūʻolo uila o nā kaʻa uila maʻamau, ʻoi aku ka nui o ka ikehu o nā pūnaeau hydrogen, hiki ke hāʻawi i ke kaʻa kaʻa lōʻihi, a ʻoi aku ka maikaʻi no ka hoʻokele kaʻa lōʻihi. Eia kekahi, ʻoi aku ka liʻiliʻi o nā kaʻa hydrogen wahie e hoʻopiha ai me ka hydrogen, ʻoi aku ka maʻalahi ma mua o nā kaʻa uila rechargeable.

Eia nō naʻe, ke kū nei nā kaʻa kaʻa wahie hydrogen i kekahi mau pilikia. ʻO ka mea mua, ʻo ka hana ʻana a me ka mālama ʻana i ka hydrogen he pilikia. I kēia manawa, hana ʻia ka hapa nui o ka hydrogen ma o ka hoʻoponopono ʻana i nā wahie fossil a i ʻole electrolysis o ka wai, nā kaʻina hana e koi ai i ka nui o ka ikehu a me nā kumuwaiwai. Eia kekahi, pono ka mālama ʻana i ka hydrogen a me ka lawe ʻana i nā lako kūikawā a me nā ʻōnaehana, e hoʻohui i ke kumukūʻai a me ka paʻakikī. ʻO ka lua, ke kiʻekiʻe nei ke kumukūʻai o nā kaʻa hydrogen wahie. Hoʻohālikelike ʻia me nā kaʻa wahie maʻamau a me nā kaʻa uila, ʻoi aku ka kiʻekiʻe o nā kaʻa kaʻa hydrogen wahie i ka hana ʻana a me ka mālama ʻana, e kaupalena ana i ko lākou komo ʻana i ka mākeke.

ʻOiai kekahi mau pilikia, e paʻa mau ana nā kaʻa wahie hydrogen i ka mana nui i ka wā e hiki mai ana. Me ka holomua o ka ʻenehana a me ka hohonu o ka noiʻi a me ka hoʻomohala ʻana, e hoʻomaikaʻi ʻia ke kumukūʻai hana a me ka ʻenehana mālama ʻana o ka hydrogen, a laila e hōʻemi ana i ke kumukūʻai o nā kaʻa kaʻa hydrogen. Eia kekahi, me ka hoʻohana nui ʻana o nā kumu ikehu hou e like me ka mana o ka lā a me ka makani, ʻoi aku ka maikaʻi o ka hana ʻana o ka hydrogen i ke kaiapuni a hoʻomau. ʻOiai ke kūkulu ʻana i kahi ʻōnaehana hydrogen piha, ʻo ke kākoʻo a me ka hoʻopukapuka ʻana o ke aupuni a me nā ʻoihana e hāpai pū i ka hoʻomohala ʻana i nā kaʻa kaʻa hydrogen.

Ma ke ʻano holoʻokoʻa, loaʻa i nā kaʻa hydrogen wahie he nui nā pono ma ke ʻano he ala maʻemaʻe a maikaʻi hoʻi o ka lawe ʻana. Hōʻike ʻia lākou e ka zero emissions, kiʻekiʻe o ka ikehu kiʻekiʻe a me ka lōʻihi o ka holo ʻana, a ke manaʻo ʻia nei e lilo i koho koʻikoʻi ma ke kahua o ka lawe ʻana i ka wā e hiki mai ana. ʻOiai kekahi mau paʻakikī, e hoʻomau ka hoʻonui ʻana o ka mākeke a me ka hoʻomau ʻana o nā kaʻa hydrogen fuel cell e like me ka holomua ʻana o ka ʻenehana a me nā ʻoihana.
