Indima Ebalulekile Yokubuyiselwa Kwe-NGL Enkathini Yokubusa Ngemva Kwe-Methane
Ekuthuthukisweni okubalulekile kokuvuselelwa kwamafutha okuthuthukisiwe, ucwaningo lwamuva nje olushicilelwe ku-Imibiko Yesayensikuye kwakhanyisa okusha ngezici ze-oxidation yokushisa okuphansi (i-LTO) zama-reservoirs kawoyela alula. Lolu cwaningo, olugxile ekusebenzeni endaweni kawoyela yaseXinjiang eShayina, lwembula ukuziphatha okuyinkimbinkimbi ngokwesigaba ngesikhathi sokukhukhula komoya, ikakhulukazi ukuthi isikhathi se-oxidation kanye nokugcwala kwamanzi kuthinta kanjani ukusebenza kahle kokufuduka kukawoyela.Lokhu kuphumelela ekuqondeniukutakula uwoyela olulakufika ngesikhathi esibalulekile. Njengoba opharetha bomhlaba wonke befuna ukwandisa umkhiqizo ovela ezimpahleni ezikhona, ukusebenzisana phakathi kwamasu okukhipha ayinkimbinkimbi kanye nengqalasizinda yokucubungula ubuso akukaze kube yinto ebaluleke kangaka.
Ngesikhathi esifanayo, isimo sokulawula siyaqina. Ngemva kwezithembiso ezinkulu ze-COP28, ukuphothulwa kwemithetho eqinile ye-methane yi-US EPA kuphoqa imboni kawoyela negesi ukuthi iqede ukuvutha okuvamile futhi ivale ngamandla ukuvuza kwe-methane.Lokhu kucindezela okubili—okuthuthukisa ukubuyiselwa komhlabathi ngaphansi komhlaba ngenkathi kuhambisana nemiyalelo yokukhishwa komoya okungaphezu komhlabathi—kushukumisela abaqhubi ukuthi bafune izixazululo ezingagcini nje ngokuhlukanisa uketshezi lwegesi yemvelo oluyigugu (ama-NGL) kodwa futhi ezizoyenza ngendlela ephumelelayo.
Yilapho isimanjeIsitshalo sokuvuselela i-NGL ishintsha kusuka kuyunithi yokucubungula elula ibe yisikhungo senzuzo esinobuhlakani. Ngokubamba i-ethane, i-propane, kanye ne-butane ebezizovutha noma zishiywe emseleni wegesi owomile, abaqhubi bangakwazi ukunciphisa kakhulu izindleko zokuthobela imithetho. Kodwa-ke, indlela yendabuko yokwakha ingqalasizinda enkulu, ephakathi nendawo ivame ukungafaneleki ngendlela esakazwa ngayo amaphrojekthi okubuyisa uwoyela athuthukisiwe noma ukuguquguquka okudingekayo kuma-well pads akude.
Ubuhlakani bemakethe busikisela isisombululo esicacile sale nkinga yezokuthutha. Imakethe yomhlaba wonke yezitshalo ezincane ze-LNG kanye nezitshalo zokuphuza uketshezi kulindeleke ukuthi ikhule isuka ku-USD 11.46 billion ngo-2025 iye ku-USD 20.45 billion ngo-2031, ngenxa yesidingo sezixazululo zamandla ezihlukaniswe ngokwezigaba.Abahlaziyi bezimboni baphinde baphawule ukuthi ingxenye yoketshezi izobamba isabelo semakethe esivelele, esikhuthazwa ukuthunyelwa okusheshayo kanye nokukhula kwezitshalo ezihlanganisiwe.
Sikholelwa ukuthi ikusasa eliseduze lilele ekuhlanganisweni kwamaphrojekthi athuthukisiwe okubuyisa uwoyela kanye namakhono okwelapha ahlukaniswe ngokwezinga. Okutholakele kwe-Xinjiang kuqinisekisa ukuthi ukukhulisaukutakula uwoyela olulangokuvamile kuhilela ukuphathwa kwegesi okuyinkimbinkimbi. Ngokuhlanganisa i-compactIsitshalo sokuvuselela i-NGLngqo endaweni yokukhiqiza, abaqhubi bangacubungula igesi ehlobene nale misebenzi yokubuyisa ethuthukisiwe khona manjalo. Lokhu akugcini nje ngokunciphisa ukukhishwa kwe-methane okuqondiswe yimithetho emisha ye-EPA kodwa futhi kuveza ama-NGL anenani eliphezulu okusetshenziswa noma ukuthengiswa kwezimboni zasendaweni.
Ngaphezu kwalokho, igesi eyomile esele iyisithako esifanele sokudlaIsitshalo esincane se-LNGNjengoba kuqokonyiswe emibikweni yakamuva yezasolwandle neyezimboni, isidingo se-LNG njengophethiloli ogcina ugesi kanye namandla angaphandle kwegridi siyakhula, njengoba amaphrojekthi amasha okugcina ugesi kanye namaphrojekthi angaphansi komfula engena "esigabeni sokukhula esiholwa amandla" ngo-2026Esikhundleni sokubukaukwelashwa kwegesi yemveloNjengesikhungo sezindleko sokuthobela imithetho, abaqhubi abacabanga kusengaphambili bakubheka njengesinyathelo sokuqala ochungechungeni lokuhlinzekwa kwamandla olusendaweni.
