Kwiminyaka yakutshanje, amandla e-hydrogen aphinde avela njengesihloko esibalulekileyo kwicandelo elitsha lamandla. Ishishini le-hydrogen lichazwe ngokucacileyo njengelinye lamashishini aphambili asakhulayo ophuhliso, kunye namacandelo afana nezixhobo ezintsha kunye namayeza amatsha. Iingxelo zigxininisa imfuneko yokukhulisa iinjini ezintsha zokukhula, kubandakanya ukwenziwa kwezinto eziphilayo, i-aerospace yorhwebo, kunye noqoqosho olusezantsi, ngelixa zibeka phambili ngokucacileyo ukukhawuleziswa kophuhliso lweshishini le-hydrogen okokuqala. Oku kugxininisa amandla amakhulu e-hydrogen.
Okwangoku, imveliso yehydrogen esekelwe kumalahle ilawula ulwakhiwo lobonelelo, ibalwa ngama-64%, ilandelwa yihydrogen evela kwimveliso yemizi-mveliso (21%), ihydrogen esekelwe kwigesi yendalo (14%), kunye nezinye iindlela (1%). Oku kutyhila ukuba imveliso yehydrogen esekelwe kwipetroli yeefosili ilawula ngokupheleleyo kwi-99%, ngelixa "ihydrogen eluhlaza" esekelwe kwi-electrolysis kunye nezinye iindlela zihlala zingaphantsi. Ngenxa yoko, izikhululo zangoku zokufunxa ihydrogen zisebenzisa ikakhulu le modeli ilandelayo yokugcina nokuthutha imveliso: Iinkampani zePetrochemical kwiindawo ezikude zivelisa ihydrogen kwiifosili, zicinezela ihydrogen enoxinzelelo oluphantsi (ngesiqhelo ~1.5MPa) ukuya kwi ~20MPa zisebenzisa iicompressor, kwaye ziyigcina kwiitreyila zeetyhubhu ze-22MPa. Ihydrogen emva koko ithuthwa iye kwizikhululo zokufunxa, apho iphantsi koxinzelelo lwesibini ukuya kwi-45MPa kwizithuthi zeseli yepetroli. Le modeli yahlulwe ngokwendawo inyusa iindleko zothutho, iindleko zezixhobo, kunye nokusetyenziswa kwexesha, ngelixa ihlala ithintelwe yimveliso "yehydrogen engwevu" exhomekeke kwipetroli yeefosili.
Ngaphezu koko, phantsi kwemithetho ekhoyo ngoku, i-hydrogen ichazwa njengekhemikhali enobungozi enokutsha neqhumayo. Ngenxa yoko, iiprojekthi zemveliso ye-hydrogen zigxile kakhulu kwiindawo ezikude zeekhemikhali ezineemfuno ezingqongqo zokhuseleko kunye nokusingqongileyo.
Ngokuphucuka kwetekhnoloji ye-electrolysis, iindleko zemveliso ye-hydrogen eluhlaza ziyehla kancinci kancinci. Kwangaxeshanye, imigaqo-nkqubo yokusingqongileyo efana "nokufikelela kwi-carbon peak kunye nokungathathi cala kwe-carbon" iqhuba i-hydrogen eluhlaza ukuba ibe yindlela ebalulekileyo yophuhliso lwamandla egesi kwixesha elizayo. I-International Energy Agency iqikelela ukuba ngo-2030, ubuchwepheshe be-hydrogen ene-carbon ephantsi efana ne-electrolysis buya kubalelwa kwi-14% yemarike ye-hydrogen, nto leyo echaphazela kakhulu uyilo lwezikhululo zokuzalisa amafutha. Imveliso esekelwe kwi-electrolysis, kunye nokutya kwayo okulula nokufikelelekayo, ivumela ukuveliswa kwe-hydrogen ngaphaya kweepaki zekhemikhali zemveli. Ukucinezelwa ngokuthe ngqo kwe-hydrogen eveliswa kwindawo yokuzalisa amafutha kwizithuthi kuphelisa ukuthuthwa komgama omde kunye nokucinezelwa kwesibini, kunciphisa ngokufanelekileyo iindleko zoqoqosho nexesha.
Ukuze zihambelane nothungelwano lwe-hydrogen olusekelwe kwi-fossil fuel, iintlobo ezimbini zee-diaphragm compressors zilawula imarike okwangoku: 1) Iiyunithi zokuzalisa i-hydrogen ezine-~1.5MPa intake pressure kunye ne-20-22MPa discharge pressure; 2) Ii-Refueling station compressors ezine-5-20MPa intake pressure kunye ne-45MPa discharge pressure. Nangona kunjalo, le nkqubo inamanqanaba amabini ifuna ukusebenza okudibeneyo kweeyunithi zombini. Ngaphezu koko, xa uxinzelelo lwe-hydrogen storage cylinder luhla ngaphantsi kwe-5MPa, ii-refueling compressors azikwazi ukusebenza, nto leyo ebangela ukuba amazinga okusetyenziswa kwe-hydrogen aphantsi.
Ngokwahlukileyo koko, izikhululo zokugcwalisa i-hydrogen ezidityanisiweyo zibonisa ukusebenza kakuhle okuphezulu. Kule modeli, i-hydrogen evela kwi-electrolysis inokucinezelwa ngokuthe ngqo ukusuka kwi-~1.5MPa ukuya kwi-45MPa kusetyenziswa i-diaphragm compressor enye, nto leyo enciphisa kakhulu iindleko zezixhobo kunye nexesha. Umlinganiselo woxinzelelo oluphantsi lokungenisa (1.5MPa vs. 5MPa) ukwaphucula kakhulu ukusetyenziswa kwe-hydrogen.
Njengoko iteknoloji ye-electrolysis iqhubela phambili, kulindeleke ukuba izitishi ze-hydrogen ezidityanisiweyo zamkelwe ngokubanzi, nto leyo eqhuba imfuno yemarike ye-1.5MPa-to-45MPa diaphragm compressors. Inkampani yethu inamandla oyilo kunye nemveliso apheleleyo okubonelela ngezisombululo ezenzelwe wena kule meko yesicelo. Njengoko inani elikhulayo lemveliso ye-hydrogen eluhlaza, izitishi ezidityanisiweyo kulindeleke ukuba zande, zandise amathuba okusetyenziswa kwe-diaphragm compressors kunye nepotifoliyo yemveliso yethu ngelixa zibonelela ngezisombululo ezintsha zokugcwalisa amafutha.
Nangona kunjalo, imingeni isaqhubeka ekuphuhliseni izikhululo ze-hydrogen ezidibeneyo kunye nee-compressor ezinxulumene nazo, kubandakanya iindleko eziphezulu ze-electrolysis, ukuhlelwa kweekhemikhali eziyingozi ze-hydrogen, kunye neziseko ze-hydrogen ezingaphelelanga. Ukujongana nale micimbi ngokufanelekileyo kuya kuba yimfuneko ekuphuculeni iinkqubo zamandla e-hydrogen ezidibeneyo.
