ʻO nā holomua i loko o ke ʻano IV Hydrogen Storage Tanks: Hoʻohui i nā mea Composite no ka palekana i hoʻonui ʻia

I kēia manawa, ʻo nā ʻenehana hoʻopaʻa hydrogen maʻamau e pili ana i ka mālama kinoea kiʻekiʻe, ka mālama wai cryogenic, a me ka mālama paʻa. Ma waena o kēia mau mea, ua puka mai ka waihona kinoea kiʻekiʻe ma ke ʻano he ʻenehana ʻoi loa ma muli o ke kumu kūʻai haʻahaʻa, ka hoʻoulu ʻana i ka hydrogen wikiwiki, ka hoʻohana ʻana i ka ikehu haʻahaʻa, a me ke ʻano maʻalahi, e hoʻolilo iā ia i ka ʻenehana mālama mālama hydrogen.

ʻEhā ʻano o nā pahu mālama wai hydrogen:

Ma waho aʻe o ka puka ʻana mai o Type V piha piha piha me ka ʻole o nā laina o loko, ʻehā ʻano o nā pahu mālama hydrogen i komo i ka mākeke:

1.Type I nā pahu metala a pau: Hāʻawi kēia mau pahu i ka mana nui ma nā kaomi hana mai ka 17.5 a hiki i ka 20 MPa, me nā kumukūʻai haʻahaʻa. Hoʻohana ʻia lākou i nā mea liʻiliʻi no nā kaʻa a me nā kaʻa CNG (compressed natural gas).

2. Type II metala-lined composite tanks: Hoʻohui kēia mau pahu i nā laina metala (maʻamau i ke kila) me nā mea i hoʻohui ʻia i ʻeha i ka ʻaoʻao hoop. Hāʻawi lākou i ka mana nui ma ka hana ʻana ma waena o 26 a me 30 MPa, me nā kumukūʻai haʻahaʻa. Hoʻohana nui ʻia lākou no nā noi kaʻa CNG.

3.Type III nā pahu hoʻohui a pau: He ʻoi aku ka liʻiliʻi o kēia mau pahu i nā kaomi hana ma waena o 30 a me 70 MPa, me nā laina metala (steel/aluminium) a me nā kumukūʻai kiʻekiʻe. Loaʻa iā lākou nā noi i nā kaʻa māmā wahie hydrogen māmā.

4.Type IV nā pahu hoʻohui i hoʻopaʻa ʻia i ka plastik: Hāʻawi kēia mau pahu i ka mana liʻiliʻi ma nā kaomi hana ma waena o 30 a me 70 MPa, me nā laina i hana ʻia me nā mea e like me polyamide (PA6), polyethylene kiʻekiʻe (HDPE), a me nā plastic polyester (PET) .

ʻO nā pono o ka Type IV Hydrogen Storage Tanks:

I kēia manawa, hoʻohana nui ʻia nā tank Type IV i nā mākeke honua, ʻoiai ʻo Type III ka mea i hoʻomalu i ka mākeke mālama mālama hydrogen.

Ua ʻike maopopo ʻia inā ʻoi aku ka nui o ke kaomi hydrogen ma mua o 30 MPa, hiki ke hoʻihoʻi ʻia ka hydrogen embrittlement, e alakaʻi ana i ka ʻino o ka liner metala a hopena i nā māwae a me nā haʻihaʻi. Hiki i kēia kūlana ke alakaʻi i ka leaka hydrogen a me ka pahū ma hope.

Hoʻohui ʻia, he ʻokoʻa ka like ʻole o ka metala alumini a me ke kalapona kalapona i ka papa wili, e pili pono ana ma waena o ka liner alumini a me ka wili kalapona i hiki ke ʻino. No ka pale ʻana i kēia, ua hoʻohui ka poʻe noiʻi i kahi papa corrosion hoʻokuʻu ma waena o ka liner a me ka ʻāpana wili. Eia nō naʻe, hoʻonui kēia i ke kaumaha holoʻokoʻa o nā pahu mālama hydrogen, hoʻohui i nā pilikia logistical a me nā kumukūʻai.

ʻO ka lawe ʻana i ka hydrogen palekana: kahi mea nui:
Ke hoʻohālikelike ʻia me Type III tanks, Type IV hydrogen storage tanks e hāʻawi i nā pono koʻikoʻi e pili ana i ka palekana. ʻO ka mea mua, hoʻohana nā pahu kaʻa Type IV i nā liner non-metallic i haku ʻia me nā mea hana like me ka polyamide (PA6), polyethylene kiʻekiʻe (HDPE), a me nā plastic polyester (PET). Hāʻawi ka Polyamide (PA6) i ka ikaika tensile maikaʻi loa, ka pale ʻana i ka hopena, a me ka wela hoʻoheheʻe kiʻekiʻe (a hiki i 220 ℃). Hōʻike ka polyethylene kiʻekiʻe (HDPE) i ke kūpaʻa wela maikaʻi loa, ke kūʻē ʻana i ke koʻikoʻi o ke kaiapuni, ka paʻakikī, a me ka pale ʻana i ka hopena. Me ka hoʻoikaika ʻana o kēia mau mea hoʻohui plastik, hōʻike nā pahu Type IV i ke kūpaʻa ʻoi aku ka maikaʻi o ka hydrogen embrittlement a me ka corrosion, e hopena i kahi ola lawelawe lōʻihi a hoʻonui i ka palekana. ʻO ka lua, ʻo ke ʻano māmā o nā mea hoʻohui plastik e hōʻemi i ke kaumaha o nā pahu, e hopena i nā kumukūʻai logistical haʻahaʻa.

Ka hopena:
ʻO ka hoʻohui ʻana o nā mea i hoʻohui ʻia i loko o nā pahu mālama hydrogen Type IV kahi holomua nui i ka hoʻonui ʻana i ka palekana a me ka hana. ʻO ka hoʻopaʻa ʻia ʻana o nā liner non-metallic, e like me ka polyamide (PA6), ka polyethylene kiʻekiʻe (HDPE), a me ka polyester plastics (PET), e hoʻomaikaʻi i ka pale ʻana i ka hydrogen embrittlement a me ka corrosion. Eia kekahi, ʻo nā hiʻohiʻona māmā o kēia mau mea hoʻohui plastik e hāʻawi i ka hoʻemi ʻana i ke kaumaha a me nā kumukūʻai logistical haʻahaʻa. I ka loaʻa ʻana o ka hoʻohana nui ʻana o nā pahu Type IV i nā mākeke a noho mau nā pahu Type III, ʻo ka hoʻomohala mau ʻana o nā ʻenehana mālama hydrogen he mea koʻikoʻi no ka ʻike ʻana i ka piha piha o ka hydrogen ma ke ʻano he kumu ikehu maʻemaʻe.
