1.Hoʻoulu ʻia ka ikehu mai ka hydrogen ma ka hoʻohana ʻana i nā compressors
ʻO ka hydrogen ka wahie me ka ikehu kiʻekiʻe loa no ke kaumaha.ʻO ka mea pōʻino, ʻo ka nui o ka hydrogen i nā kūlana lewa aia wale nō ma 90 grams i kēlā me kēia mika cubic.I mea e hoʻokō ai i nā pae hiki ke hoʻohana ʻia o ka nui o ka ikehu, pono ka hoʻoemi pono ʻana o ka hydrogen.
2.ʻO ka hoʻoemi kūpono o ka hydrogen mediaphragmnā compressors
ʻO kekahi manaʻo hoʻopiʻi i hōʻoia ʻia ʻo ka diaphragm compressor.Hoʻopili maikaʻi kēia mau mea hoʻoheheʻe hydrogen i ka liʻiliʻi a me ka liʻiliʻi o ka hydrogen i ke kiʻekiʻe, a inā makemake ʻia, ʻoi aku ka nui o nā kaomi kiʻekiʻe ma mua o 900 bar.ʻO ka loina diaphragm e hōʻoiaʻiʻo i ka ʻaila-a me ka leakage manuahi me ka maʻemaʻe huahana maikaʻi loa.ʻOi aku ka maikaʻi o nā compressors diaphragm ma lalo o ka ukana mau.I ka holo ʻana ma lalo o ke kaʻina hana intermittent hiki ke emi ke ola o ka diaphragm a hiki ke hoʻonui ʻia ka lawelawe.
3.Piston compressors no ke kaomi ʻana i ka nui o ka hydrogen
Inā makemake ʻia ka nui o ka hydrogen aila ʻole me ka liʻiliʻi ma mua o 250 bar pressure, ʻo ka nui o nā kaukani piston i hōʻoia ʻia a hoʻāʻo ʻia ka piston compressors maloʻo ka pane.ʻOi aku ma mua o 3000kW o ka mana kaʻa hiki ke hoʻohana maikaʻi ʻia no ka hoʻokō ʻana i nā koi kōmike hydrogen.
No nā kahe kiʻekiʻe a me nā puʻe kiʻekiʻe, ʻo ka hui ʻana o NEA Piston pae me nā poʻo diaphragm ma kahi compressor "hybrid" e hāʻawi i kahi solution compressor hydrogen maoli.
1.No ke aha ʻo Hydrogen?(Pono)
Ka mālama ʻana a me ka lawe ʻana i ka ikehu me ka hydrogen compressed
Me ka Paris Agreement of 2015 , Ma ka 2030 e hoʻemi ʻia ka hoʻokuʻu ʻia ʻana o ke kinoea ʻōmaʻomaʻo e 40% i ka hoʻohālikelike ʻia me 1990. , kūʻokoʻa mai nā kūlana o ka wā, pono nā mea lawe ikehu ʻē aʻe a me nā ʻano mālama.ʻO ka Hydrogen (H2) ka mea hiki ke mālama i ka ikehu.Hiki ke hoʻololi i ka ikehu hou e like me ka makani, ka lā a i ʻole ka mana wai i Hydrogen a laila mālama ʻia a lawe ʻia me ke kōkua o nā mea hoʻoheheʻe hydrogen.Ma kēia ala hiki ke hoʻohui ʻia ka hoʻohana mau ʻana i nā kumuwaiwai kūlohelohe me ka pōmaikaʻi a me ka hoʻomohala ʻana.
4.1ʻO nā mea hoʻoheheʻe hydrogen ma nā hale ʻaila
ʻO ka hui pū me nā kaʻa uila uila (BEV) nā kaʻa uila uila (FCEV) me ka hydrogen ma ke ʻano he wahie ke kumuhana nui no ka neʻe ʻana o ka wā e hiki mai ana.Aia nā kūlana a ke koi nei lākou i nā kaomi hoʻokuʻu a hiki i 1,000 bar.
4.2ʻO ka halihali alanui i hoʻohana ʻia i ka hydrogen
ʻO ka manaʻo nui no ka lawe ʻana i ke alanui i hoʻohana ʻia i ka hydrogen e pili ana i ka halihali ukana me nā kaʻa māmā a kaumaha a me nā semis.ʻAʻole hiki ke hoʻokō ʻia kā lākou koi ikaika nui no ka hoʻomanawanui lōʻihi i hui pū ʻia me nā manawa refueling pōkole me ka ʻenehana pākaukau.He nui wale nā mea hoʻolako i nā kaʻa uila uila hydrogen ma ka mākeke.
4.3ʻO ka hydrogen i ka lawe kaʻaahi
No ke kaʻa kaʻa kaʻa ma nā wahi me ka lako ʻole o ka laina laina, hiki i nā kaʻaahi hydrogen ke hoʻololi i ka hoʻohana ʻana i nā mīkini hana diesel.Ma nā ʻāina he nui o ka honua, ua hoʻohana mua ʻia ka lima mua o ka hydrogen-electric me ka laulā o ka hana ma mua o 800 km (500 mile) a me ka wikiwiki o 140kph (85 mph).
4.4ʻO ka hydrogen no ka lawe ʻana i ka moana no ke aniau neutral zero emission
Loaʻa nō hoʻi ka hydrogen i kona ala i loko o ke aniau neutral zero emission maritime transport.ʻO nā ferry mua a me nā moku liʻiliʻi liʻiliʻi e holo ana ma ka hydrogen ke hoʻāʻo ikaika nei.Eia kekahi, ʻo nā wahie synthetic i hana ʻia mai ka hydrogen a me CO2 i hopu ʻia he koho no ka halihali moana kūʻokoʻa.Hiki ke lilo kēia mau wahie i hana ʻia i wahie no ka mokulele o ka wā e hiki mai ana.
4.5Hydrogen no ka wela a me ka ʻoihana
ʻO ka hydrogen kahi mea kumu nui a me ka reactant i nā kemika, petrochemical a me nā kaʻina hana ʻoihana ʻē aʻe.
Hiki iā ia ke kākoʻo i ka hoʻopili ʻana i ka ʻāpana kūpono i ke ala Power-to-X i kēia mau noi.ʻO Power-to-Steel no ka laʻana ka pahuhopu o ka hana kila "de-fossilizing".Hoʻohana ʻia ka mana uila no ka hoʻoheheʻe ʻana.Hiki ke hoʻohana ʻia ʻo CO2 neutral Hydrogen i mea pani no ka coke i ke kaʻina hoʻemi.I loko o nā hale hana hoʻomaʻemaʻe hiki iā mākou ke loaʻa nā papahana mua e hoʻohana ana i ka hydrogen i hana ʻia e ka electrolysis e laʻa no ka desulphurization o nā wahie.
Aia pū kekahi mau noi ʻoihana liʻiliʻi mai nā pahu hoʻoheheʻe ʻia a hiki i ka hydrogen wahie cell emergency units.ʻO ka hoʻolako hope, e like me nā micro fuel cell no nā hale a me nā hale ʻē aʻe, ka mana a me ka wela a ʻo kā lākou pauku wale nō ka wai maʻemaʻe.
