ʻO 45% o nā kalapona kalapona i ka honua ʻoihana ʻoihana mai ke kaʻina hana o ke kila, synthetic ammonia, ethylene, cement, a me nā mea ʻē aʻe. Loaʻa i ka ikehu hydrogen nā ʻano ʻelua o ka ʻoihana maka a me nā huahana ikehu, a ua manaʻo ʻia he mea nui a hiki ke hiki. hoʻonā i ka decarbonization hohonu o ka ʻoihana. Me ka emi nui o ke kumu kūʻai o ka ikehu hou, e hoʻoponopono mālie ʻia ka pilikia o ke kumukūʻai hydrogen ʻōmaʻomaʻo, a ua manaʻo ʻia ka "ʻoihana + hydrogen ʻōmaʻomaʻo" e komo i ka ʻoihana kemika e kōkua i nā hui kemika e hoʻokō i ka loiloi waiwai.
ʻO ke koʻikoʻi o ka "green hydrogen" i ke komo ʻana i ke kaʻina hana ma ke ʻano he kemika maka no nā ʻoihana kemika a me ka hao a me ke kila, hiki iā ia ke hoʻokō i nā pono o ka hoʻohana ʻana i ka ikehu a me ka hoʻokuʻu kalapona i ka manawa like, a hāʻawi pū i nā pono waiwai hou no nā ʻoihana. hāʻawi i wahi ulu ʻoihana hou.
ʻAʻohe mea kānalua he kumu nui ka ʻoihana kemika. I nā makahiki he 10 e hiki mai ana, e ulu mau ana ka noi huahana o ka ʻoihana kemika, akā ma muli o ka hoʻoponopono ʻana o ka hana hana a me ka hoʻolālā huahana, e loaʻa pū kekahi hopena i ka koi no ka hydrogen. Akā ʻo ka laulā, ʻo ka ʻoihana kemika i nā makahiki he 10 e hiki mai ana ka piʻi nui o ka koi no ka hydrogen. I ka wā lōʻihi, i nā koi ʻole-carbon, e lilo ka hydrogen i mea kumu kemika, a me ka ʻoihana kemika hydrogen.
Ma ka hoʻomaʻamaʻa, aia nā papahana ʻenehana a me nā papahana hōʻike e hoʻohana ana i ka hydrogen ʻōmaʻomaʻo ma ke ʻano he mea maka e hoʻohui i ke kaʻina hana kemika lanahu, hoʻomaikaʻi i ka hoʻohana ʻana i ka hoʻokele waiwai o nā ʻātoma kalapona, a hoʻemi i nā hoʻokuʻu kalapona. Eia kekahi, aia nā hydrogen ʻōmaʻomaʻo e hana i ka ammonia synthetic e hana i ka "ammonia ʻōmaʻomaʻo", hydrogen ʻōmaʻomaʻo e hana i ka methanol e hana i ka "ʻona ʻōmaʻomaʻo" a me nā ʻenehana ʻenehana ʻē aʻe i lawe ʻia ma Kina. Manaʻo ʻia i loko o nā makahiki he 10 e hiki mai ana, ua manaʻo ʻia ka ʻenehana i luna e hoʻokō i kahi holomua o ke kumukūʻai.
I ka "hao a me ke kila 'oihana ho'ēmi 'ia", "e hōʻoia i ka makahiki-ma-makahiki emi i ka crude hana kila" koi, a me ka lohi paipai 'ana o scrap recycling a me ka hydrogen pololei emi hao a me nā 'enehana 'ē aʻe, ua manaoia ka oihana. i ka wā e hiki mai ma luna o kuʻuna blast smelting hao koi coking hiki ke emi, coking ma-huahana hydrogen emi, akā, ma muli o hydrogen koi o hydrogen pololei hoemi hao enehana, hydrogen metallurgy e loaa breakthrough ulu. ʻO kēia ʻano o ka hoʻololi ʻana i ke kalapona me ka hydrogen ma ke ʻano he mea hoʻohaʻahaʻa i ka hana hao e hoʻohua ai ke kaʻina hana hao i ka wai ma mua o ka carbon dioxide, ʻoiai e hoʻohana ana i ka hydrogen e hāʻawi i nā kumu wela kiʻekiʻe, no laila e hōʻemi nui ai i ka hoʻokuʻu ʻia ʻana o ke kinoea ʻōmaʻomaʻo, i manaʻo ʻia he ʻōmaʻomaʻo. hana hana no ka oihana kila. I kēia manawa, nui nā ʻoihana kila ma Kina e hoʻoikaika ikaika nei.
Ua akaka iki ka noi ʻoihana no ka mākeke hydrogen ʻōmaʻomaʻo, ākea ka manaʻo o ka mākeke e hiki mai ana. Eia nō naʻe, ʻekolu mau kūlana no ka hoʻohana nui ʻana o ka hydrogen ma ke ʻano he mea maka i loko o nā māla kemika a me ke kila: 1. Pono e haʻahaʻa ke kumukūʻai, ʻaʻole ia i emi iho i ke kumu kūʻai o ka hydrogen hina; 2, haʻahaʻa kalapona emission pae (me ka uliuli hydrogen a me ka uliuli hydrogen); 3, pono ke kaumaha o ke kulekele "lua kalapona" i ka wā e hiki mai ana, i ʻole, ʻaʻohe ʻoihana e lawe i ka manaʻo e hoʻoponopono.
Ma hope o nā makahiki o ka hoʻomohala ʻana, ua komo ka ʻoihana hoʻomohala mana hou i kahi pae o ka hoʻomohala nui, ke hoʻomau nei ka emi ʻana o ke kumukūʻai o ka mana photovoltaic a me ka mana makani. Ke emi nei ke kumu kūʻai o "ka uila ʻōmaʻomaʻo" ʻo ia hoʻi e komo ka hydrogen ʻōmaʻomaʻo i ke kahua ʻoihana a lilo i mea paʻa, haʻahaʻa, noi nui o nā mea hana kemika. I nā huaʻōlelo ʻē aʻe, manaʻo ʻia ka hydrogen ʻōmaʻomaʻo haʻahaʻa e hoʻoponopono hou i ke ʻano o ka ʻoihana kemika a wehe i nā ala hou no ka ulu ʻana o ka ʻoihana kemika!
