Amathuba amasha okukhuthaza intuthuko esimeme: ukugxila kushintshela kubuchwepheshe bokubuyisa igesi evuthayo
Ngomongo wokuguqulwa kwamandla emhlabeni jikelele, ubuchwepheshe bokubuyisa igesi evuthayo buya ngokuya buba yinkinga ebalulekile embonini kawoyela negesi. Muva nje, umbiko okhishwe yi-International Energy Agency (IEA) ukhombe ukuthi umhlaba uchitha ama-cubic metres ayizigidigidi eziyi-150 zegesi yemvelo minyaka yonke ngenxa yokuqhuma kwegesi evuthayo, okungagcini nje ngokubangela ukumoshwa okukhulu kwezinsizakusebenza, kodwa futhi okunomthelela omkhulu emvelweni. Njengoba amazwe enaka kakhulu imigomo yokunciphisa ukukhishwa kwegesi evuthayo, amathuba okusetshenziswa kobuchwepheshe bokubuyisa igesi evuthayo aya ngokuya eba banzi.
Ingqikithi yobuchwepheshe bokubuyisa igesi evuthayo ukusebenzisa kabusha nokusebenzisa igesi eshisiwe ekuqaleni bese uyiguqula ibe amandla avuselelekayo noma eminye imikhiqizo ebalulekile. Ikakhulukazi ku Izitshalo ze-LNG futhi Izitshalo zokubuyisa i-NGL, ukusetshenziswa kobuchwepheshe bokubuyisa igesi elivuthayo kungathuthukisa kakhulu ukusebenza kahle kwezinsizakusebenza futhi kunciphise izindleko zokusebenza. Ngokusho kwezikhungo zocwaningo lwemakethe, isilinganiso sokukhula esimaphakathi sonyaka semakethe yokubuyisa igesi elivuthayo sizofinyelela ku-15% eminyakeni emihlanu ezayo, okunikeza amathuba amakhulu emakethe ezinkampani ezihlobene.
Kulesi simo, izinkampani eziningi seziqalile ukwandisa ukutshalwa kwezimali kwazo kubuchwepheshe bokubuyisa igesi evuthayo. Isibonelo, inkampani yamandla eyaziwayo isanda kumemezela ukuthi izokwethula uhlelo oluthuthukisiwe lokubuyisa igesi evuthayo esitshalweni sayo se-LNG eNyakatho Melika, okulindeleke ukuthi ibuyise igesi yemvelo engaphezu kwama-cubic metres ayizigidi ezi-5 minyaka yonke futhi iyiguqule ibe ugesi ukuze ihlinzeke. Ijeneretha yegesi engu-1000kw amasethi, angagcini nje ngokuthuthukisa ukusetshenziswa kwezinsizakusebenza, kodwa futhi aletha izinzuzo ezinkulu kwezomnotho enkampanini.
Kodwa-ke, ukukhuthazwa kobuchwepheshe bokubuyisa igesi evuthayo akunazo izinselelo. Ukuvuthwa kobuchwepheshe, izindleko zokutshalwa kwezimali kanye nokusekelwa kwenqubomgomo konke kuyizinto ezibalulekile ezithinta intuthuko yabo. Noma kunjalo, njengoba umhlaba unaka kakhulu intuthuko esimeme, ohulumeni kanye nezinhlangano zezimboni nabo bakhuthaza ngenkuthalo ukwethulwa kwezinqubomgomo ezifanele ukukhuthaza izinkampani ukuthi zamukele ukutakula igesi yokuqhuma ubuchwepheshe.
