Ua hoʻāʻo ʻelua mau ʻoihana i ka hoʻohana ʻana o ka hydrogen e hoʻomehana i ke kila ma kahi keʻena ma Suedena, kahi neʻe i hiki ke kōkua i ka hana e hoʻomau i ka ʻoihana.
Ma mua o kēia pule ʻO ʻOvako, ka mea loea i ka hana ʻana i kahi ʻano kila e kapa ʻia he kila ʻenekini, ua ʻōlelo ʻo ia i hana pū me Linde Gas ma ka papahana ma ka Hofors mill mill.
No ka hoʻāʻo ʻana, ua hoʻohana ʻia ka hydrogen me he wahie lā e hoʻoulu ai i ka wela ma kahi o ka aila ʻaila ʻaihue. Ua ʻimi ʻo Ovako e hoʻomālamalama i ka pono o ke kaiapuni o ka hoʻohana ʻana i ka hydrogen i ke kaʻina kuni, me ka hoʻomaopopo ʻana ʻo ka wai wale nō i hoʻokuʻu ʻia i hana ʻia ka mahu wai.
"ʻO kēia kahi hoʻomohala nui no ka ʻoihana kila," ʻo Göran Nyström, ka pelekikena hope o Ovako no ka hui pūʻulu a me ka ʻenehana, i ʻōlelo ʻia i loko o kahi ʻōlelo.
"ʻO ia ka manawa mua e hoʻohana ʻia ai ka hydrogen e hoʻomehana i ke kila i kahi hanana hana e noho nei," i hoʻohui ʻia.
"Mahalo i ka hoʻāʻo ʻana, ʻike mākou hiki ke hoʻohana maʻalahi ʻia ka hydrogen, me ka hopena ʻole o ka maikaʻi o ke kila, ʻo ia hoʻi ka hōʻemi nui loa o ka paepae carbon."
E like me nā ʻoihana ʻenehana he nui ka hopena o ka ʻoihana kila i ke kaiapuni. Wahi a ka World Steel Association, ma ka awelika, 1.85 metric tone o carbon dioxide i hoʻoili ʻia no kēlā me kēia metric tona o kila i hana ʻia ma 2018. Ua wehewehe ka International Energy Agency i ka ʻāpana kila e "hilinaʻi nui i ka lanahu, nāna e hāʻawi 75% o koi ikaika. "
He wahie no ka wā e hiki mai ana?
Ua wehewehe ke Komisina ʻEulopa i ka hydrogen ma ke ʻano he halihali ikehu me ka "hiki kūpono no ka mana maʻemaʻe, pono i nā noi paʻa, lawe lima a me nā lawe lawe."
ʻOiai he mea hiki ke loaʻa ka hydrogen, aia kekahi mau pilikia i ka wā e hana ai.
E like me ka US Department of Energy i hōʻike ai, ʻaʻole he hydrogen maʻa mau "kū ma ke kūlohelohe" a pono e hana ʻia mai nā pūhui i loaʻa iā ia.
ʻO nā kumuwaiwai - mai nā wahie fossil a me ka lā, i ka geothermal - hiki ke hana i ka hydrogen. Inā hoʻohana ʻia nā kumuwaiwai hou i kāna hana, ua kapa ʻia “hydrogen green.”
ʻOiai ke hopohopo nei ke kumukūʻai, ua ʻike ʻia nā makahiki i hala aku nei i ka hydrogen i hoʻohana ʻia i nā ʻano o nā halihali e like me nā kaʻaahi, nā kaʻa a me nā kaʻa.
I ka laʻana hou loa o nā ʻoihana halihali nui e hana ana i nā ʻanuʻu e pahu i ka ʻenehana i ka mainstream, ua hoʻolaha aku nei ka Volvo Group a me Daimler Truck i nā hoʻolālā no kahi hana like e nānā ana i ka ʻenehana hydrogen fuel-cell.
Ua ʻōlelo nā ʻoihana ʻelua ua hoʻokumu lākou i kahi hui hui 50/50, ke nānā nei e "hoʻomohala, hana a kūʻai aku i nā ʻōnaehana wahie no nā noi kaʻa hana kaumaha a me nā hihia hoʻohana ʻē aʻe."
