Ka waihona ikehu kemikahoʻohana i ka ikehu uila e hoʻohuli i nā mea ikehu haʻahaʻa i mea ikehu kiʻekiʻe no ka mālama ʻana, pēlā e loaʻa ai ka mālama ʻana i ka ikehu. I kēia manawa, ʻo nā ʻenehana i hoʻohana nui ʻia ma ke kahua o ka mālama ʻana i ka ikehu kemika, ʻo ia ka mālama ʻana i ka ikehu hydrogen a me ka wahie synthetic (e like me ka methane a me ka methanol). Hiki ke hoʻohana pololei ʻia kēia mau waihona mālama e like me nā kumu ikehu. No laila, ma kēia ʻano, ʻokoʻa ka mālama ʻana i ka ikehu kemika mai nā kaʻina mālama ikehu kuʻuna kahi i hoʻokomo a me ka hoʻopuka ʻana he ikehu uila. Inā hiki i nā mea hoʻohana hope ke hoʻohana pololei i nā mea e like me ka hydrogen a i ʻole ka methane (e laʻa, i loko o nā kaʻa kaʻa hydrogen wahie, hui pū ʻana a me nā ʻōnaehana mana, a i ʻole ka ʻoihana kemika), ʻaʻole pono e hoʻohuli hou ʻia kēia mau ʻano ikehu i mālama ʻia i ka ikehu uila i loko o ka ʻōnaehana mana. Hoʻololi maikaʻi kēia ʻano hoʻohana pono ʻana i ka waihona "kekona lua" i kahi kumu hoʻolaʻa "tertiary energy" ʻoi aku ka maikaʻi. No laila, he loulou koʻikoʻi ka waihona ikehu kemika i ke kaʻina hana hoʻololi ikehu, e hāʻawi ana i nā pono e like me ka nui o ka ikehu kiʻekiʻe, ka lōʻihi o ka mālama ʻana, a me ka pālākiō maʻalahi, no laila, kūpono ia no ka wā lōʻihi,-nui ka mālama ikehu. Eia kekahi, hiki i ka mālama ʻana i ka ikehu kemika ke hoʻohana i nā ʻenehana ikehu i loaʻa, e like me nā pipeline gas kūlohelohe a me nā hale mālama wahie liquefied, e hōʻemi ana i nā kumukūʻai. No laila, ʻoi aku ka nui o ka mālama ʻana i ka ikehu kemika no ka hoʻomohala ʻana i ka pilina o ka ikehu hou, ke koi wela o ka ʻoihana, a me ka halihali, ʻoi aku ka nui o ka hoʻoponopono ʻana i ka volatility o ka ikehu hou.
Waihona ikehu hydrogen
ʻO ka mālama ʻana i ka ikehu hydrogen kahi ʻenehana e hoʻololi i ka ikehu uila i hydrogen no ka mālama ʻana. ʻO kāna kumu nui ka hana ʻana i ka hydrogen ma o ka electrolysis wai a i ʻole nā kaʻina kemika ʻē aʻe, a me ka hoʻokuʻu ʻana i ka ikehu i ka wā e pono ai ma o nā wahie a i ʻole ka puhi ʻana. ʻO ka hydrogen, ma ke ʻano he kumu ikehu lua maʻemaʻe, ʻike ʻia ka nui o ka ikehu kiʻekiʻe a me ka hoʻokuʻu kalapona ʻole, a hoʻohana nui ʻia i ka lawe ʻana, ʻoihana, a me ka mālama ʻana i ka ikehu. ʻO nā pilikia koʻikoʻi o ka ʻenehana mālama hydrogen aia i ka hana kūpono, mālama a me ka lawe ʻana i ka hydrogen. I kēia manawa, ʻo nā ʻano hoʻopaʻa hydrogen koʻikoʻi, ʻo ia ka -puʻi hydrogen storage, cryogenic liquid hydrogen storage, a me -state hydrogen storage (e like me ka metala hydride hydrogen storage). ʻOiai ʻoi aku ka pipiʻi o nā ʻōnaehana mālama hydrogen, me nā holomua ʻenehana, ʻoi aku ka hoʻomohala ʻana i nā ʻenehana hana hydrogen ʻōmaʻomaʻo, ua manaʻo ʻia ka mālama ʻana i ka ikehu hydrogen kekahi o nā mea koʻikoʻi no ka loaʻa ʻana o ka decarbonization hohonu a me ka hoʻohuli ʻana i ka ikehu i ka wā e hiki mai ana, kūpono no ka nui -scale, lōʻihi -manawa mālama ikehu a kaumaha-pono lawe kaʻa.
Hoʻopaʻa ikehu wahie synthetic
Hoʻohana ka waihona wahie synthetic i ka uila e hana i nā wahie kemika (e like me ke kinoea kūlohelohe synthetic a me nā wahie wai synthetic) no ka -hoʻopaʻa ikehu lōʻihi. Hoʻopili maʻamau kēia ʻenehana i ka wai electrolyzing e hana i ka hydrogen, a laila hui pū ʻia me carbon dioxide e synthesize hydrocarbons e like me ka methane, methanol, a i ʻole synthetic diesel. Hiki ke mālama a lawe ʻia kēia mau wahie synthetic, a i ka wā e pono ai, e hoʻololi ʻia i ka uila a i ʻole ka ikehu mechanical ma o ka puhi ʻana a i ʻole i loko o nā wahie. Aia ka maika'i o ka waiho 'ana i ka wahie synthetic ma kona 'olu'olu me ka 'oihana ikehu e noho nei, e like me na paipu kinoea maoli e noho nei, ka waihona wahie wai a me ka ho'ohelehele 'ana i mea kūpono no ka manawa lō'ihi, -nui. Eia kekahi, hiki ke hoʻohana ʻia nā wahie synthetic ma ke ʻano he kumu -kahi kumu hoʻonui i ka hoʻoulu ʻana i ka ikehu hou, e kōkua ana i ke kaulike ʻana i ka pahu mana. ʻOiai ʻoi aku ka haʻahaʻa o ka pono holoʻokoʻa o nā wahie synthetic a me nā kumukūʻai kiʻekiʻe, me ka piʻi ʻana o ka ikehu hou a me nā holomua o ka hopu kalapona a me ka ʻenehana hoʻohana ʻana, ua manaʻo ʻia e lilo ka waiho ʻana i nā wahie synthetic i mea nui o nā ʻōnaehana ikehu carbon haʻahaʻa e hiki mai ana.
