He aha nā pōmaikaʻi a me nā pōʻino o nā kaʻa hydrogen ikehu i hoʻohālikelike ʻia me nā kaʻa uila maʻemaʻe?

　1. Ma ke ano o ka ikehu manawa piha

He pōkole loa ka manawa e hoʻouka ai i ke kaʻa hydrogen, ʻaʻole ma mua o 5 mau minuke.ʻOiai ʻo ke kaʻa uila e hoʻopaʻa nei i kēia manawa he hapalua hola e hoʻopaʻa ai i kahi kaʻa uila maʻemaʻe;

2. Ma ke ano o ka holo ana

Hiki i ka huakaʻi holo o nā kaʻa wahie hydrogen ke hiki i 650-700 kilomita, a hiki i kekahi mau hiʻohiʻona ke hiki i 1,000 kilomita, ʻaʻole hiki i kēia manawa no nā kaʻa uila maʻemaʻe;

3. ʻenehana hana a me ke kumukūʻai

Hoʻopuka wale nā ​​kaʻa wahie hydrogen i ka ea a me ka wai i ka wā o ka hana ʻana, ʻaʻohe pilikia o ka hoʻihoʻi hou ʻana i ka wahie, he mea maikaʻi loa ia.ʻOiai ʻaʻole hoʻohana nā kaʻa uila i ka wahie, loaʻa ʻole ka hoʻokuʻu ʻana, a ke hoʻololi wale nei i nā hoʻokuʻu pollution, no ka mea, ʻo ka mana wela o ka lanahu ka mea kiʻekiʻe loa o ka hui ʻana o ka ikehu uila o Kina.ʻOiai ʻoi aku ka maikaʻi o ka hoʻomohala ʻana i ka mana kikowaena a ʻoi aku ka maʻalahi o ka hoʻohaʻahaʻa ʻana i nā pilikia haumia, ʻo ia hoʻi, ʻaʻole maikaʻi loa nā kaʻa uila ke ʻole ko lākou uila mai ka makani, ka lā a me nā kumu ikehu maʻemaʻe ʻē aʻe.Eia kekahi, he pilikia nui ka hana hou ʻana i nā ʻeke i hoʻopau ʻia no nā pā EV.ʻAʻole haumia nā kaʻa uila maʻemaʻe, akā loaʻa iā lākou ka pollution indirect, ʻo ia hoʻi, ka pollution kaiapuni i hoʻokumu ʻia e ka mana wela.Eia nō naʻe, ma ke ʻano o ka hana o kēia manawa a me nā kumukūʻai ʻenehana o nā kaʻa kaʻa hydrogen a me nā kaʻa uila, paʻakikī loa ka ʻenehana a me ke ʻano o nā kaʻa hydrogen wahie.ʻO nā kaʻa wahie hydrogen e hilinaʻi nui i ka hydrogen a me ka hopena oxidation e hoʻoulu i ka uila e hoʻokele i ka mīkini, a koi i ka platinum metala makamae ma ke ʻano he catalyst, e hoʻonui nui ai i ke kumukūʻai, no laila he haʻahaʻa ke kumukūʻai o nā kaʻa uila maʻemaʻe.

4. Ka ikaika o ka ikehu

ʻOi aku ka maikaʻi o nā kaʻa hydrogen ma mua o nā kaʻa uila.Ke helu nei ka poʻe loea ʻoihana i ka wā e hoʻomaka ai ke kaʻa uila, e nalowale ana ka mana o ke kaʻa ma kahi o 5%, e hoʻonui ʻia ka uku pākaukau a me ka hoʻokuʻu ʻana i 10%, a ma hope e nalowale ke kaʻa he 5%.E helu i ka huina poho e like me 20%.Hoʻohui ka kaʻa kaʻa hydrogen i ka mea hoʻopiʻi i loko o ke kaʻa, a ʻo ke ala hoʻokele hope e like me ke kaʻa uila maʻemaʻe, i hoʻokele ʻia e ke kaʻa uila.Wahi a nā ho'āʻo kūpono, inā hoʻohana ʻia ka 100 kWh o ka uila e hana i ka hydrogen, a laila mālama ʻia, lawe ʻia, hoʻohui ʻia i ke kaʻa, a laila hoʻololi ʻia i uila e hoʻokele ai i ke kaʻa, ʻo 38% wale nō ka hoʻohana ʻana i ka uila, a me ka hoʻohana ʻana. ʻO ka helu he 57% wale nō.No laila ʻaʻole pehea ʻoe e helu ai, ʻoi aku ka haʻahaʻa ma mua o nā kaʻa uila.

I ka hōʻuluʻuluʻana, me ka ulu wikiwikiʻana o nā kaʻa ikehu hou, nā kaʻa ikehu hydrogen a me nā kaʻa uila ko lākou pono a me nā hemahema.ʻO nā kaʻa uila ke ʻano o kēia manawa.No ka mea he nui nā pōmaikaʻi o nā kaʻa hydrogen-powered, ʻoiai ʻaʻole lākou e hoʻololi i nā kaʻa uila i ka wā e hiki mai ana, e hoʻomohala lākou i ka synergistically.
