ʻO ka mālama ʻana a me ka lawe ʻana i ka wai hydrogen ke kumu o ka noi palekana, kūpono, nui a me nā kumu kūʻai haʻahaʻa o ka wai hydrogen, a ʻo ke kī hoʻi e hoʻoponopono i ka noi ʻana o ke ala ʻenehana hydrogen.
 
Hiki ke hoʻokaʻawale ʻia ka mālama ʻana a me ka lawe ʻana o ka hydrogen wai i ʻelua mau ʻano: ka mālama pahu a me ka lawe pipeline. Ma ke ʻano o ka hale mālama, hoʻohana pinepine ʻia ka pahu mālama spherical a me ka pahu mālama cylindrical no ka mālama ʻana i ka pahu a me ka halihali. Ma ke ʻano o ka lawe ʻana, hoʻohana ʻia ka wai hydrogen trailer, wai kaʻa kaʻa kaʻa kaʻa a me ka moku wai wai.
 
Ma waho aʻe o ka noʻonoʻo ʻana i ka hopena, vibration a me nā mea ʻē aʻe e pili ana i ke kaʻina o ka lawe ʻana i ka wai maʻamau, ma muli o ka haʻahaʻa haʻahaʻa o ka paila o ka wai hydrogen (20.3K), liʻiliʻi latent wela o ka vaporization a me nā hiʻohiʻona evaporation maʻalahi, pono e hoʻohana ka pahu pahu a me ka lawe ʻana i nā ʻano ʻenehana ikaika e hōʻemi i ka lele ʻana o ka wela, a i ʻole e hoʻohana i ka mālama ʻole a me ka lawe ʻana, e hōʻemi i ke kiʻekiʻe o ka vaporization o ka wai. Alakaʻi i ka pilikia overpressure a i ʻole ka nalowale ʻana. E like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei, mai ka hiʻohiʻona o nā ʻenehana, mālama ka wai hydrogen a me ka lawe ʻana i ka ʻenehana adiabatic passive e hōʻemi i ka conduction wela a me ka ʻenehana refrigeration ikaika i hoʻopaʻa ʻia ma luna o kēia kumu e hōʻemi i ka leaka wela a i ʻole e hoʻonui i ka mana hoʻomaha.
 
Ma muli o nā waiwai kino a me nā kemika o ka hydrogen wai ponoʻī, ʻo kona mālama ʻana a me ke ʻano o ka lawe ʻana he nui nā mea maikaʻi ma mua o ke ʻano o ka mālama ʻana i ka hydrogen gaseous kiʻekiʻe i hoʻohana nui ʻia ma Kina, akā ʻo kāna kaʻina hana paʻakikī e loaʻa ai kekahi mau hemahema.
 
Lakiō kaumaha mālama nui, mālama kūpono a me ka lawe ʻana a me ke kaʻa
Ke hoʻohālikelike ʻia me ka mālama ʻana i ka hydrogen gaseous, ʻo ka pōmaikaʻi nui loa o ka hydrogen wai kona kiʻekiʻe kiʻekiʻe. ʻO 70.8kg/m3 ka mānoanoa o ka wai hydrogen, ʻo ia ka 5, 3 a me 1.8 manawa o 20, 35, a me 70MPa kiʻekiʻe-puʻe hydrogen. No laila, ʻoi aku ka maikaʻi o ka hydrogen wai no ka mālama nui a me ka lawe ʻana i ka hydrogen, hiki ke hoʻoponopono i nā pilikia o ka mālama ʻana i ka ikehu hydrogen a me ka lawe ʻana.
 
ʻO ke kaomi haʻahaʻa haʻahaʻa, maʻalahi e hōʻoia i ka palekana
ʻO ka mālama wai hydrogen ma ke kumu o ka insulation e hōʻoia i ka paʻa o ka pahu, ʻoi aku ka haʻahaʻa o ke kaomi o ka mālama ʻana i kēlā me kēia lā a me ka lawe ʻana (ma lalo o 1MPa), ʻoi aku ka haʻahaʻa ma mua o ke kiʻekiʻe o ke kaomi kiʻekiʻe a me ka mālama hydrogen a me ka lawe ʻana, ʻoi aku ka maʻalahi e hōʻoia i ka palekana i ka hana o kēlā me kēia lā. Hoʻohui pū ʻia me nā ʻano o ka nui o ka wai hydrogen e mālama ai i ke kaupaona ʻana, i ka wā e hiki mai ana ka hoʻolaha nui ʻana o ka ikehu hydrogen, ka mālama ʻana o ka wai hydrogen a me ka halihali (e like me ka wai hydrogen hydrogenation station) e ʻoi aku ka palekana o ka ʻōnaehana hana ma nā kūlanakauhale me ka nui o ka hale, ka nui o ka lehulehu a me ke kumu kūʻai ʻāina kiʻekiʻe.
 
ʻO ka maʻemaʻe kiʻekiʻe o ka vaporization, e hoʻokō i nā koi o ka terminal
ʻO ka honua makahiki ka hoʻohana ʻana i ka hydrogen maʻemaʻe kiʻekiʻe a me ka hydrogen ultra-pure he nui, ʻoi aku ka nui o ka ʻoihana uila (e like me nā semiconductor, electro-vacuum material, silicon wafers, optical fiber manufacturing, etc.) I kēia manawa, ʻaʻole hiki i ka maikaʻi o ka hydrogen ʻoihana ke hoʻokō i nā koi koʻikoʻi o kekahi mau mea hoʻohana hope i ka maʻemaʻe o ka hydrogen, akā ʻo ka maʻemaʻe o ka hydrogen ma hope o ka vaporization o ka hydrogen wai hiki ke hoʻokō i nā koi.
 
He kiʻekiʻe ka hoʻopukapuka kālā a me ka hoʻohana ikehu kiʻekiʻe
Ma muli o ka lohi o ka hoʻomohala ʻana i nā mea hana nui a me nā ʻenehana e like me nā pahu anuanu hydrogen liquefaction, ua monopoli ʻia nā mea hoʻoheheʻe hydrogen a pau i ke kahua aerospace kūloko e nā hui ʻē aʻe ma mua o Kepakemapa 2021. ʻO kēia ka mea e hoʻonui ai i nā lako hana mua o ka mea kanu wai wai hydrogen, i hui pū ʻia me ke koi liʻiliʻi o ka home no ka hydrogen wai kīwila, ʻaʻole lawa ka nui o ka noi, a piʻi mālie ke ʻano o ka hiki. ʻO ka hopena, ʻoi aku ka kiʻekiʻe o ka hoʻohana ʻana i ka ikehu o ka wai hydrogen ma mua o ka hydrogen kiʻekiʻe.
 
Aia ka evaporation poho i loko o ke kaʻina o ka wai hydrogen waihona a me ka halihali
I kēia manawa, i ke kaʻina o ka mālama ʻana i ka hydrogen wai a me ka lawe ʻana, ʻo ka evaporation o ka hydrogen i hoʻokumu ʻia e ka leakage wela ke mālama ʻia e ka venting, kahi e alakaʻi ai i kahi degere o ka nalowale o ka evaporation. I ka wā e hiki mai ana ka mālama ʻana i ka ikehu hydrogen a me ka lawe ʻana, pono e lawe ʻia nā hana hou e hoʻihoʻi i ke kinoea hydrogen i hoʻoheheʻe ʻia e hoʻonā i ka pilikia o ka hoʻemi ʻana i ka hoʻohana ʻana ma muli o ka hoʻokuʻu pololei ʻana.

ʻO HL Cryogenic Equipment i hoʻokumu ʻia ma 1992 he hōʻailona pili i ka HL Cryogenic Equipment Company Cryogenic Equipment Co., Ltd. Hoʻokumuʻia ka HL Cryogenic Equipment i ka hoʻolālā a me ka hanaʻana i ka High Vacuum Insulated Cryogenic Piping System a me nā mea kākoʻo e pili ana i nā mea e pono ai nā mea kūʻai. ʻO ka Vacuum Insulated Pipe a me Flexible Hose i kūkulu ʻia i loko o kahi ʻenekini kiʻekiʻe a me ka multi-layer multi-screen insulated mea kūikawā, a hele i ke ʻano o nā ʻenehana koʻikoʻi koʻikoʻi a me ka hoʻomaʻamaʻa haʻahaʻa kiʻekiʻe, i hoʻohana ʻia no ka hoʻoili ʻana o ka oxygen wai, wai nitrogen, wai argon, wai hydrogen, wai helium, liquefied ethylene kinoea LNG.
