Ma ke ʻano he kumu ikehu kalapona ʻole, ua huki ka ikehu hydrogen i ka honua holoʻokoʻa. I kēia manawa, ʻike ʻia ka hoʻomohala ʻana o ka ikehu hydrogen i nā pilikia koʻikoʻi, ʻoi aku ka nui o ka hana ʻana o ka ʻenehana haʻahaʻa haʻahaʻa a me nā ʻenehana lawe lōʻihi, ʻo ia nā pilikia bottleneck i ke kaʻina o ka noi hydrogen.
 
Ke hoʻohālikelike ʻia me ka mālama ʻana i ke kinoea kiʻekiʻe a me ke ʻano hāʻawi hydrogen, ʻo ka haʻahaʻa haʻahaʻa haʻahaʻa wai waihona a me ke ʻano hāʻawi i nā pono o ke kiʻekiʻe o ka mālama ʻana o ka hydrogen (high hydrogen carrying density), ke kumukūʻai haʻahaʻa haʻahaʻa, ka maʻemaʻe vaporization kiʻekiʻe, ka haʻahaʻa haʻahaʻa. Eia kekahi, ʻoi aku ka maikaʻi o ka wai hydrogen i ka hana ʻana, ka mālama ʻana a me ka lawe ʻana i nā mea kūpono no ka hāʻawi ʻana i ka ikehu hydrogen. Eia nō naʻe, me ka hoʻomohala wikiwiki ʻana o ka ʻoihana noi terminal o ka ikehu hydrogen, e hoʻihoʻi ʻia ke koi no ka hydrogen wai.
 
ʻO ka wai hydrogen ke ala maikaʻi loa e mālama ai i ka hydrogen, akā ʻo ke kaʻina o ka loaʻa ʻana o ka wai hydrogen he paepae ʻenehana kiʻekiʻe, a pono e noʻonoʻo ʻia kona hoʻohana ʻana i ka ikehu a me ka pono i ka wā e hana ai i ka hydrogen wai ma kahi nui.
 
I kēia manawa, hiki i ka 485t / d ka nui o ka hana hydrogen wai honua. ʻO ka hoʻomākaukau ʻana i ka wai hydrogen, hydrogen liquefaction technology, hiki mai i nā ʻano he nui a hiki ke hoʻokaʻawale ʻia a hui pū ʻia paha ma ke ʻano o nā kaʻina hana hoʻonui a me nā kaʻina hoʻololi wela. I kēia manawa, hiki ke hoʻokaʻawale ʻia nā kaʻina hana hydrogen liquefication maʻamau i ke kaʻina Linde-Hampson maʻalahi, e hoʻohana ana i ka hopena Joule-Thompson (JT effect) e throttle hoʻonui, a me ke kaʻina hana hoʻonui adiabatic, e hui pū ana me ka turbine expander. Ma ke kaʻina hana maoli, e like me ka hoʻopuka o ka wai hydrogen, hiki ke hoʻokaʻawale ʻia ke ʻano hoʻonui adiabatic i ke ʻano Brayton hoʻohuli, e hoʻohana ana i ka helium ma ke ʻano he haʻahaʻa haʻahaʻa no ka hoʻonui ʻana a me ka refrigeration, a laila hoʻoluʻu kiʻekiʻe-pressure gaseous hydrogen i ka wai moku, a me ke ʻano Claude, ka mea e hoʻomaha ai i ka hydrogen ma o ka hoʻonui adiabatic.
 
ʻO ka loiloi kumu kūʻai o ka hana hydrogen wai e noʻonoʻo nui i ka nui a me ka hoʻokele waiwai o ke ala ʻenehana wai hydrogen. I ke kumu kūʻai o ka wai hydrogen, ʻo ke kumu kūʻai hydrogen e lawe i ka hapa nui loa (58%), a ukali ʻia e ke kumukūʻai hoʻohana ikehu piha o ka ʻōnaehana liquefaction (20%), helu ʻia no 78% o ka huina kālā o ka wai hydrogen. Ma waena o kēia mau kumukūʻai ʻelua, ʻo ka mana koʻikoʻi ke ʻano o ke kumu hydrogen a me ke kumukūʻai uila kahi i loaʻa ai ka mea kanu wai. ʻO ke ʻano o ke kumu hydrogen pili pū me ke kumukūʻai uila. Inā kūkulu ʻia kahi mea kanu electrolytic hydrogen a me kahi mea kanu liquefaction i hui pū ʻia e pili ana i ka hale mana i nā wahi e hoʻoulu ai i ka ikehu hou, e like me nā ʻāpana ʻekolu ʻākau kahi i hoʻopaʻa ʻia ai nā mana makani nui a me nā mea kanu photovoltaic a i ke kai paha, hiki ke hoʻohana ʻia ka uila haʻahaʻa no ka hana electrolysis wai hydrogen a me ka hoʻoheheʻe ʻana, a hiki ke hoʻemi ʻia ke kumu kūʻai o ka wai hydrogen. I ka manawa like, hiki iā ia ke hōʻemi i ka mana o ka mana makani makani nui pili i ka mana peaking o ka ʻōnaehana mana.
 
HL Cryogenic Lako
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.
