ʻOi aku ka maikaʻi o ka hana ʻana i nā wahie a me nā pahu hydrogen no ke kaiapuni ma mua o nā pihi [ICCT]

Ma kahi o hoʻokahi mahina i hala aku nei, ua hoʻokuʻu ka International Clean Transport Council (ICCT) i kahi hōʻike e pili ana i ka hoʻokuʻu ʻana mai ka hana ʻana, ka hoʻohana ʻana a me ka hoʻopau ʻana i nā kaʻa puhi ahi, nā plug-in hybrids, nā kaʻa uila a me nā kaʻa wahie (hydrogen). Kahaha paha ka mea nana i nana pono i na palapala. pʻO ka hana ʻana o ka pākaukau ka hopena i ka hoʻokuʻu ʻia ʻana o ke kinoea hoʻouluulu haʻahaʻa a me ka haʻahaʻa haʻahaʻa o ke kaiapuni ma mua o ka hana ʻana o nā wahie a me nā pahu hydrogen..

ʻOi aku ka maikaʻi o nā pahu wai hydrogen no ke kaiapuni ma mua o nā pila. A ke kamaʻilio wale nei mākou e pili ana i ka hoʻonohonoho ʻana, ʻaʻole ka hana.

Hiki ke kiʻi ʻia ka ICCT LCA Report (Life Cycle Analysis) HERE. Eia kekahi o nā pakuhi i ʻōlelo ʻia, e ʻike i ka ʻaoʻao 16 o ka hōʻike. Melemele - ka hana ʻana o nā pā i ka honua hou (me ke koena o ka ikehu o kēia manawa), ʻulaʻula - ka hana ʻana o kahi pahu hydrogen me nā wahie. ʻoi aku ka ʻino:

Pīhoihoi iki, ua nīnau mākou iā ICCT e pili ana i kēia mau ʻokoʻa no ka mea Ua ʻae ʻia ʻo ka unuhi ʻana o nā mea maka a me ka hana ʻana i nā pā lithium-ion he "palapala" nā kaʻina, a ʻo nā wahie a i ʻole nā ​​pahu hydrogen i manaʻo ʻia he maʻemaʻe.no ka mea, "ʻaʻole lākou a pau i kēia mea lapuwale." ʻIke ʻia ʻaʻohe hewa: ma ke ʻano o ka hoʻoiho CO₂, ʻoi aku ka maikaʻi o ke kaiapuni a me ka liʻiliʻi o ka pōʻino i ke kaiapuni ma mua o ka hana ʻana o nā cell a me nā waihona.

Ua haʻi mai ʻo Kauka Georg Bicker, ka mea kākau alakaʻi o ka hōʻike, ua hoʻohana ʻo ia i ke kumu hoʻohālike GREET i hoʻomohala ʻia e Argonne National Laboratory, kahi keʻena noiʻi no ka US Department of Energy, e hoʻomākaukau i nā ʻōlelo. E koʻikoʻi mākou: ʻaʻole kēia he ʻano kikowaena noiʻi, akā he mea, ʻike ʻia nā hopena ma ke kahua o ka ikehu nuklea, nā kumu ikehu ʻē aʻe a me ka radioactivity a puni ka honua.

Ma muli o ka nui o ke kaʻa a me kahi e kūʻai aku ai, ʻo ia hoʻi, mai ke kumu pākahi, hoʻokuʻu ʻia ke kinoea ʻōmaʻomaʻo (GHG) mai ka 1,6 tonnes o CO like.₂ no nā hatchback liʻiliʻi ma India (23 kWh pākahiko) a hiki i 5,5 tons o CO like.₂ no nā SUV a me nā SUV ma ka US (92 kWh pākahi; Papa 2.4 ma lalo). Ma ka awelika no nā ʻāpana āpau e pili ana i 3-3,5 tons o CO-equivalent.₂... Hana ʻia hoʻokaʻawale ʻia e pili ana i ka hana hou ʻana, inā ʻo ia, he 14-25 pakeneka ka haʻahaʻa, ma muli o ke kaʻina hana hou a me ka nui o nā mea maka i hoʻihoʻi ʻia.

No ka hoʻohālikelike: hana o ka wahie keena a me ka hydrogen pahu emits 3,4-4,2 tons o CO like₂ e like me ke kumu hoʻohālike GREET a i ʻole 5 tons o CO like₂ i nā hiʻohiʻona ʻē aʻe (pp. 64 a me 65 o ka hoike). ʻO ka paradoxically, ʻaʻole ia ka hoʻihoʻi ʻana o ka platinum i hoʻohana ʻia i loko o nā wahie wahie e lawe i ke kaumaha nui loa ma ke kaiapuni, akā. ka hana ʻana o nā pahu hydrogen composite i hoʻoikaika ʻia i ka fiber carbon... ʻAʻole ia he mea kupanaha no ka pale ʻana o ka cylinder i ke kaomi nui o 70 MPa, no laila ke kaupaona ʻia he mau ʻumi kilokani, ʻoiai hiki iā ia ke paʻa i kekahi mau kilokani kinoea.
