Ua lilo ka ikehu hydrogen i ala nui no ka hooulu ikehu

No ka manawa lōʻihi, ua hoʻohana nui ʻia ka hydrogen ma ke ʻano he kinoea maka i ka hoʻomaʻemaʻe ʻaila, ka amonia synthetic a me nā ʻoihana ʻē aʻe. I nā makahiki i hala iho nei, ua ʻike mālie nā ʻāina a puni ka honua i ke koʻikoʻi o ka hydrogen i ka ʻōnaehana ikehu a ua hoʻomaka e hoʻomohala ikaika i ka ikehu hydrogen. I kēia manawa, 42 mau ʻāina a me nā ʻāpana o ka honua i hoʻopuka i nā kulekele ikehu hydrogen, a ke hoʻomākaukau nei nā ʻāina a me nā ʻāpana ʻē aʻe 36 i nā kulekele ikehu hydrogen. Wahi a ka International Hydrogen Energy Commission, e piʻi ka huina kālā i US $ 500 biliona e 2030.

Mai ka hiʻohiʻona o ka hana hydrogen, ʻo Kina wale nō i hana i 37.81 miliona tons o ka hydrogen i ka makahiki 2022. ʻOiai ʻo ia ka mea hana hydrogen nui loa o ka honua, ʻo ke kumu kumu nui o ka hydrogen i kēia manawa ʻo ka hydrogen hina, ʻo ia ka nui o ka hana hydrogen ma muli o ka lanahu, a ukali ʻia e ke kinoea hydrogen. hana (Hana ʻia ka Hydrogen ma o ka hoʻoponopono mahu) a me kekahiKA HO'OPONOPONO ANA I KA HYDROGEN MA METANOLaPressure swing adsorption hydrogen hoʻomaʻemaʻe (PSA-H2), a ʻo ka hana ʻana o ka hydrogen hina e hoʻopuka i ka nui o ka carbon dioxide. No ka hoʻoponopono ʻana i kēia pilikia, haʻahaʻa-carbon renewable energy production hydrogen,hopu kalapona, ka ho'ohana 'ana a me ka mālama 'ana i nā 'ike loea no ka ho'omohala 'ana; Eia kekahi, ʻo ka hydrogen huahana ʻoihana ʻaʻole e hoʻopuka i ke kalapona dioxide hou (me ka hoʻohana piha ʻana i nā hydrocarbons māmā, coking a me nā kinikona chlor-alkali) e hoʻonui nui ʻia. I ka wā lōʻihi, e lilo ka hana hydrogen ikehu hou, me ka ikehu hou i ka wai electrolysis hydrogen production, e lilo i ke ala hana hydrogen mainstream.

Mai ka manaʻo noiʻi, ʻo ka noi lalo a Kina e hoʻolaha nui nei i kēia manawa ʻo ia nā kaʻa kaʻa hydrogen wahie. Ma ke ʻano he kākoʻo kākoʻo no nā kaʻa kaʻa wahie, ke wikiwiki nei ka hoʻomohala ʻana o nā hale hoʻoheheʻe hydrogen ma Kina. Hōʻike nā noiʻi ma ʻApelila 2023, ua kūkulu ʻia ʻo Kina ma mua o 350 mau hale hoʻoheheʻe hydrogen; e like me nā hoʻolālā o nā panalāʻau like ʻole, nā kūlanakauhale a me nā ʻāpana kūʻokoʻa, ʻo ka pahuhopu kūloko ke kūkulu ʻana i kahi kokoke i 1,400 hydrogen refueling stations ma ka hopena o 2025. ʻAʻole hiki ke hoʻohana wale ʻia ka hydrogen ma ke ʻano he ikehu maʻemaʻe, akā he mea hoʻohana kemika e kōkua ai. mālama nā hui i ka ikehu a hoʻemi i ka hoʻokuʻu ʻana, a i ʻole synthesize i nā kemika kiʻekiʻe me ka carbon dioxide.
