I-Evolution ye-Hydrogen Production: Igesi yendalo vs. Methanol

I-Hydrogen, i-energy carrier eguquguqukayo, iya iqatshelwa ngendima yayo kwinguqu kwikamva lamandla azinzileyo. Iindlela ezimbini ezibalaseleyo zokuvelisa i-hydrogen kwishishini kungegesi yendalo kunye ne-methanol. Indlela nganye ineenzuzo zayo ezizodwa kunye nemingeni, ebonisa ukuguquka okuqhubekayo kubuchwepheshe bamandla.

IGesi yeNdalo yeHydrojeni (inkqubo yokulungiswa komphunga)

Irhasi yendalo, eyona nto yenziwa yimethane, yeyona nto ixhaphakileyo kwimveliso yehydrogen kwihlabathi liphela. Inkqubo, eyaziwa ngokubaukuhlaziya i-methane yomphunga(SMR), ibandakanya ukuphendula imethane ngomphunga kumaqondo obushushu aphezulu ukuvelisa ihydrogen kunye necarbon dioxide. Le ndlela ithandwa ngokusebenza kwayo kunye nokulinganisa, iyenza ibe ngumqolo wemveliso ye-hydrogen yeshishini.

Ngaphandle kokulawula kwayo, ukuthembela kwigesi yendalo kuphakamisa inkxalabo malunga nokukhutshwa kwekhabhoni. Nangona kunjalo, ukuqhubela phambili kubuchwepheshe bokubamba nokugcinwa kwekhabhoni (CCS) buyadityaniswa ukunciphisa ezi mpembelelo zokusingqongileyo. Ukongeza, uphononongo lokusebenzisa ubushushu obuvela kwiireactors zenyukliya ukunyusa imveliso ye-hydrogen yenye indawo yophando enokunciphisa ngakumbi i-carbon footprint yemveliso ye-hydrogen yendalo.

IMethanol Hydrogen Production (ukulungiswa komphunga wemethanol)

I-Methanol, ikhemikhali eguquguqukayo evela kwigesi yendalo okanye i-biomass, inika enye indlela yokuvelisa i-hydrogen. Inkqubo ibandakanyaukuguqulwa komphunga wemethanol(MSR), apho imethanol idibana nomphunga ukuvelisa ihydrogen kunye necarbon dioxide. Le ndlela ifumana ingqwalasela ngenxa yobuchule bayo obuphezulu kunye nokukhutshwa kwekhabhoni ephantsi xa kuthelekiswa nokuguqulwa kwegesi yendalo.

Inzuzo ye-Methanol ikwimeko yokugcinwa kwayo ngokulula kunye nokuthutha, ethe ngqo ngakumbi kune-hydrogen. Olu phawu luyenza ibe lukhetho olunomtsalane kwimveliso ye-hydrogen ekwabelwanayo, enokuthi inciphise imfuno yeziseko ezingundoqo. Ngaphezu koko, ukudityaniswa kwemveliso ye-methanol kunye nemithombo yamandla avuselelekayo, njengomoya kunye nelanga, kunokuphucula ngakumbi izibonelelo zayo zokusingqongileyo.

Uhlalutyo lokuthelekisa

Zombini igesi yendalo kunye ne-methanolimveliso ye-hydrogeniindlela zineenzuzo kunye nemida yazo. Irhasi yendalo okwangoku yeyona ndlela yoqoqosho nesebenzayo, kodwa i-carbon footprint yayo ihlala iyinkxalabo enkulu. I-Methanol, ngelixa ibonelela ngenye indlela ecocekileyo, isekwinqanaba lokuqala lophuhliso kwaye ijongene nemingeni ekunyuseni imveliso.

Ukhetho phakathi kwezi ndlela luxhomekeke kwizinto ezahlukeneyo, kubandakanywa ukufumaneka kwempahla yokutya, ingcamango yokusingqongileyo, kunye nenkqubela phambili yobuchwepheshe. Njengoko ihlabathi lisiya kwikamva lamandla azinzileyo, uphuhliso lweenkqubo ezixubeneyo ezidibanisa amandla ezi ndlela zombini zinokuba lukhokelo oluthembisayo.

Ukuqukumbela

Ukuziphendukela kwemvelo okuqhubekayo kwiisisombululo se-hydrogen(isityalo sokuvelisa i-hydrogen) sigxininisa ukubaluleka kokutshintsha kwemithombo yamandla kunye nokudibanisa izisombululo ezintsha. Igesi yendalo kunye nemveliso ye-methanol hydrogen imele iindlela ezimbini ezibalulekileyo ezinokuthi, xa ziphuculwe kwaye zihlanganiswe, zibe negalelo elikhulu kwinguqu yamandla yehlabathi. Njengoko uphando kunye nophuhliso luqhubeka, ezi ndlela ziya kuthi ziguquke ngakumbi, zivula indlela yoqoqosho oluzinzileyo lwe-hydrogen.
