ʻO ka mālama ʻana a me ka lawe ʻana i ka hydrogen wai ke kumu o ka palekana, kūpono, nui a me ke kumu kūʻai haʻahaʻa o ka hoʻohana ʻana i ka hydrogen wai, a ʻo ke kī hoʻi i ka hoʻoponopono ʻana i ka hoʻohana ʻana i ke ala ʻenehana hydrogen.
 
Hiki ke hoʻokaʻawale ʻia ka mālama ʻana a me ka lawe ʻana o ka hydrogen wai i ʻelua ʻano: ka mālama ʻana i nā ipu a me ka lawe ʻana i nā paipu. Ma ke ʻano o ka hoʻonohonoho mālama ʻana, hoʻohana pinepine ʻia ka pahu mālama poepoe a me ka pahu mālama cylindrical no ka mālama ʻana a me ka lawe ʻana i nā ipu. Ma ke ʻano o ka lawe ʻana, hoʻohana ʻia ka trailer hydrogen wai, ke kaʻa pahu kaʻaahi hydrogen wai a me ka moku pahu hydrogen wai.
 
Ma waho aʻe o ka noʻonoʻo ʻana i ka hopena, ka haʻalulu a me nā mea ʻē aʻe e pili ana i ke kaʻina hana o ka lawe ʻana i ka wai maʻamau, ma muli o ke kiko paila haʻahaʻa o ka hydrogen wai (20.3K), ka wela latent liʻiliʻi o ka vaporization a me nā ʻano maʻalahi o ka evaporation, pono e hoʻohana ka waihona a me ka lawe ʻana i nā ʻano loea koʻikoʻi e hōʻemi i ka leaka wela, a i ʻole e hoʻohana i ka mālama ʻana a me ka lawe ʻana ʻaʻole luku, e hōʻemi i ke kiʻekiʻe o ka vaporization o ka hydrogen wai i ka liʻiliʻi a i ʻole ka ʻole, inā ʻaʻole e hoʻonui ia i ke kaomi o ka pahu. E alakaʻi i ka pilikia overpressure a i ʻole ka pohō blowout. E like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei, mai ka manaʻo o nā ʻano loea, hoʻohana nui ka mālama ʻana a me ka lawe ʻana i ka hydrogen wai i ka ʻenehana adiabatic passive e hōʻemi i ka hoʻoili wela a me ka ʻenehana refrigeration hana i hoʻopili ʻia ma kēia kumu e hōʻemi i ka leaka wela a i ʻole e hoʻoulu i ka hiki ke hoʻoluʻu hou.
 
Ma muli o nā ʻano kino a me nā kemika o ka hydrogen wai ponoʻī, ʻo kona ʻano mālama a me ka halihali he nui nā pono ma mua o ke ʻano mālama hydrogen kinoea kiʻekiʻe i hoʻohana nui ʻia ma Kina, akā ʻo kāna kaʻina hana paʻakikī hoʻi e hana iā ia i kekahi mau hemahema.
 
ʻO ka lakio kaumaha nui o ka mālama ʻana, kahi mālama kūpono a me ka halihali a me ke kaʻa
Ke hoʻohālikelike ʻia me ka mālama ʻana i ka hydrogen gaseous, ʻo ka pōmaikaʻi nui o ka hydrogen wai ʻo ia kona nui kiʻekiʻe. ʻO ka nui o ka hydrogen wai he 70.8kg/m3, ʻo ia hoʻi he 5, 3 a me 1.8 manawa o ka hydrogen kiʻekiʻe-kaomi 20, 35, a me 70MPa. No laila, ʻoi aku ka kūpono o ka hydrogen wai no ka mālama nui ʻana a me ka lawe ʻana i ka hydrogen, hiki ke hoʻoponopono i nā pilikia o ka mālama ʻana a me ka lawe ʻana i ka ikehu hydrogen.
 
Haʻahaʻa ka nui o ka waihona, maʻalahi e hōʻoia i ka palekana
ʻO ka mālama ʻana i ka hydrogen wai ma ke kumu o ka insulation e hōʻoia i ke kūpaʻa o ka pahu, ʻo ke kiʻekiʻe o ke kaomi o ka mālama ʻana a me ka halihali i kēlā me kēia lā he haʻahaʻa (ʻoi aku ka haʻahaʻa ma mua o 1MPa), ʻoi aku ka haʻahaʻa ma mua o ke kiʻekiʻe o ke kaomi o ke kinoea kiʻekiʻe a me ka mālama ʻana a me ka halihali hydrogen, ʻoi aku ka maʻalahi o ka hōʻoia ʻana i ka palekana i ke kaʻina hana o kēlā me kēia lā. I hui pū ʻia me nā ʻano o ka lakio kaumaha mālama hydrogen wai nui, i ka wā e hiki mai ana, e loaʻa i kahi ʻōnaehana hana palekana ka hoʻolaha nui ʻana o ka ikehu hydrogen, ka mālama ʻana a me ka halihali hydrogen wai (e like me ke kahua hydrogenation hydrogenation wai) ma nā wahi kūlanakauhale me ka nui o ka hale, ka heluna kanaka nui a me ke kumukūʻai ʻāina kiʻekiʻe, a e uhi ka ʻōnaehana holoʻokoʻa i kahi wahi liʻiliʻi, e koi ana i ka liʻiliʻi o ke kumukūʻai hoʻopukapuka mua a me ke kumukūʻai hana.
 
Maʻemaʻe kiʻekiʻe o ka vaporization, e hoʻokō i nā koi o ke kikowaena
He nui loa ka hoʻohana ʻana o ka hydrogen maʻemaʻe kiʻekiʻe a me ka hydrogen ultra-pure i kēlā me kēia makahiki ma ka honua holoʻokoʻa, ʻoi aku hoʻi i ka ʻoihana uila (e like me nā semiconductors, nā mea electro-vacuum, nā wafers silicon, ka hana ʻana o nā fiber optical, a me nā mea ʻē aʻe) a me ke kahua o nā cell wahie, kahi i nui loa ai ka hoʻohana ʻana o ka hydrogen maʻemaʻe kiʻekiʻe a me ka hydrogen ultra-pure. I kēia manawa, ʻaʻole hiki i ka maikaʻi o nā hydrogen ʻoihana he nui ke hoʻokō i nā koi koʻikoʻi o kekahi poʻe hoʻohana hope loa ma ka maʻemaʻe o ka hydrogen, akā hiki i ka maʻemaʻe o ka hydrogen ma hope o ka vaporization o ka hydrogen wai ke hoʻokō i nā koi.
 
He nui ka hoʻopukapuka kālā a me ka hoʻohana ʻana i ka ikehu ma ka hale hana hoʻoheheʻe wai
Ma muli o ke kaʻulua ʻana o ka hoʻomohala ʻana i nā lako koʻikoʻi a me nā ʻenehana e like me nā pahu anuanu hydrogen liquefaction, ua hoʻopaʻa ʻia nā lako hydrogen liquefaction āpau ma ke kahua aerospace kūloko e nā ʻoihana haole ma mua o Kepakemapa 2021. Aia nā lako koʻikoʻi hydrogen liquefaction nui i nā kulekele kālepa haole pili (e like me nā Export Administration Regulations o ka US Department of Commerce), e kaupalena ana i ka lawe ʻana aku i nā lako a pāpā i ka hoʻololi ʻenehana. ʻO kēia ka mea e hoʻolilo ai i ka hoʻopukapuka mua ʻana o nā lako hana hydrogen liquefaction i mea nui, me ka liʻiliʻi o ka noi kūloko no ka hydrogen wai kīwila, ʻaʻole lawa ka nui o ka noi, a piʻi mālie ka nui o ka mana. ʻO ka hopena, ʻoi aku ka kiʻekiʻe o ka hoʻohana ʻana i ka ikehu hana o ka hydrogen wai ma mua o ka hydrogen kinoea kiʻekiʻe.
 
Aia ka nalowale ʻana o ka mahu i ke kaʻina hana o ka mālama ʻana a me ka lawe ʻana i ka hydrogen wai.
I kēia manawa, i ke kaʻina hana o ka mālama ʻana a me ka lawe ʻana i ka hydrogen wai, ʻo ka mahu ʻana o ka hydrogen i hoʻokumu ʻia e ka leaka wela e mālama ʻia ma ke ʻano he venting, kahi e alakaʻi ai i kahi kekelē o ka nalowale ʻana o ka mahu. I ka wā e hiki mai ana, pono e hana hou ʻia nā hana hou aʻe e hoʻihoʻi i ke kinoea hydrogen i mahu hapa ʻia e hoʻoponopono i ka pilikia o ka hoʻemi ʻana o ka hoʻohana ʻana i hoʻokumu ʻia e ka venting pololei.
