Ka wahie mai ka wai a me carbon dioxide

Ua hoʻomaka ka mea hana kaʻa Kelemania ʻo Audi e hana i ka diesel synthetic mai ka wai a me carbon dioxide ma Dresden. He "'ōmaʻomaʻo" kēia wahie diesel ma nā pae he nui, ʻoiai ʻo ka CO₂ no ke kaʻina hana mai ka biogas a ʻo ka uila no ka electrolysis wai mai nā kumu "maʻemaʻe".

Hoʻopili ka ʻenehana i ka electrolysis o ka wai i ka hydrogen a me ka oxygen ma kahi mahana o XNUMX degere Celsius. Wahi a Audi a me kāna hoa, ʻoi aku ka maikaʻi o kēia pae ma mua o nā ʻano electrolytic i ʻike ʻia i kēia manawa, no ka mea, hoʻohana ʻia kekahi hapa o ka ikehu wela. I ka pae aʻe, i loko o nā reactors kūikawā, hana ka hydrogen me ka carbon dioxide ma lalo o ke kiʻekiʻe kiʻekiʻe a me ka wela kiʻekiʻe. Hana ʻia kahi wahie hydrocarbon kaulahao lōʻihi i kapa ʻia ʻo "Blue Crude Oil".

Wahi a ka mea hana, ʻo ka maikaʻi o ke kaʻina hoʻololi mai ka uila hiki ke hoʻololi ʻia i nā wahie wai he 70%. A laila e hana ʻo Blue Crude i nā kaʻina hoʻomaʻemaʻe e like me ka ʻaila ʻaila e hana ai i ka wahie diesel mākaukau no ka hoʻohana ʻana i nā ʻenekini. Wahi a nā ho'āʻo, he maʻemaʻe loa ia, hiki ke hoʻohui ʻia me ka wahie diesel kuʻuna a hiki koke ke hoʻohana ʻokoʻa.
