Malinga ndi data ya Institute Research Institute,kupanga gasi wa haidrojenindondomeko panopa ili pamalo oyamba padziko lonse lapansi msika wa haidrojeni. Gawo la kupanga haidrojeni kuchokera ku gasi wachilengedwe ku China ndi lachiwiri, pambuyo pake kuchokera ku malasha. Kupanga haidrojeni kuchokera ku gasi wachilengedwe ku China kudayamba m'zaka za m'ma 1970, makamaka kupereka haidrojeni yopangira ammonia. Ndi kusintha kwa khalidwe lothandizira, kuyenda kwa ndondomeko, mlingo wolamulira, mawonekedwe a zida ndi kukhathamiritsa kwapangidwe, kudalirika ndi chitetezo cha njira yopangira gasi wa hydrogen yatsimikiziridwa.
Njira yopangira gasi wa haidrojeni makamaka imaphatikizapo njira zinayi: kupangira gasi yaiwisi, kusintha kwa nthunzi ya gasi, kusintha kwa carbon monoxide,kuyeretsedwa kwa hydrogen.
Gawo loyamba ndi zopangira pretreatment, amene makamaka amatanthauza yaiwisi mpweya desulfurization, ndondomeko yeniyeni ntchito zambiri amagwiritsa cobalt molybdenum hydrogenation mndandanda nthaka okusayidi monga desulfurizer kutembenuza organic sulfure mu gasi mu zosawerengeka sulfure ndiyeno kuchotsa izo.
Gawo lachiwiri ndikukonzanso mpweya wachilengedwe, womwe umagwiritsa ntchito chothandizira cha nickel mu okonzanso kusintha ma alkanes mu gasi wachilengedwe kukhala mpweya wa feedstock womwe zigawo zake zazikulu ndi carbon monoxide ndi hydrogen.
Gawo lachitatu ndi kusintha kwa carbon monoxide. Imachita ndi nthunzi wamadzi pamaso pa chothandizira, potero imatulutsa haidrojeni ndi mpweya woipa, ndikupeza mpweya wosuntha womwe umapangidwa makamaka ndi hydrogen ndi carbon dioxide.
Gawo lomaliza ndikuyeretsa haidrojeni, tsopano njira yomwe imagwiritsidwa ntchito kwambiri ndi hydrogen purification system ndi pressure swing adsorption (PSA) purification separation system. Dongosololi lili ndi mawonekedwe otsika mphamvu yamagetsi, njira yosavuta komanso chiyero cha hydrogen.
Kupanga haidrojeni kuchokera ku gasi wachilengedwe kuli ndi ubwino wa sikelo yayikulu yopanga haidrojeni ndi ukadaulo wokhwima, ndipo ndiye gwero lalikulu la haidrojeni pakadali pano. Ngakhale kuti gasi wachilengedwe ndi mafuta achilengedwe ndipo amatulutsa mpweya wowonjezera kutentha popanga blue hydrogen, koma chifukwa chogwiritsa ntchito matekinoloje apamwamba monga carbon capture, utilization and Storage (CCUS), yachepetsa kukhudzidwa kwa chilengedwe cha Dziko lapansi pogwira. mpweya wowonjezera kutentha ndi kukwaniritsa kupanga mpweya wochepa.
