The Inhlangano Yezindiza Yezindiza Yomhlaba Wonke (IATA) icele ohulumeni emhlabeni wonke ukuthi basekele ukuthuthukiswa kwe-Sustainable Aviation Fuel (SAF) njengesinyathelo esibalulekile sokufeza imigomo yayo yokunciphisa intuthu engcolisayo ibe yingxenye ka-2005 ngo-2050. Lokhu okuhlosiwe kuqiniswe yisinqumo eMhlanganweni Jikelele Wonyaka wama-76 we-IATA izolo nawo. ibophezela imboni ekuhloleni izindlela zokuthola ukukhishwa kwe-zero.
“Kade sazi ukuthi ukushintshwa kwamandla ku-SAF yikhona okushintshile. Kodwa ukushintsha kwamandla kudinga ukwesekwa nguhulumeni. Izindleko ze-SAF ziphezulu kakhulu futhi ukunikezwa kulinganiselwe kakhulu. Le nkinga yithuba lokushintsha lokho. Ukubeka imali yokuvuselela umnotho ngemuva kokuthuthukiswa kwemakethe enkulu, enokuncintisana ye-SAF kungaba impumelelo ephindwe kathathu—ukudala amathuba emisebenzi, ukulwa nokuguquguquka kwesimo sezulu kanye nokuxhumanisa umhlaba ngendlela eqhubekayo,” kusho u-Alexandre de Juniac, uMqondisi Jikelele kanye no-CEO we-IATA.
Amaphakheji okukhuthaza kahulumeni angasiza ekukhuthazeni i-SAF ngokutshalwa kwezimali okuqondile, iziqinisekiso zokubolekwa kwemali kanye nezinxephezelo zezinkampani ezizimele, kanye nemithethonqubo edlulisa ukudla kwezimpahla eziya emikhakheni edonsa kanzima njengeyezindiza kunezinye izimboni zezokuthutha ezinekhabhoni ephansi.
Inhloso yezimali zokukhuthaza kuzoba ukwakha imakethe ekwazi ukuncintisana. Njengamanje i-SAF ibiza ngokuphindwe ka-2-4 ngaphezu kukaphethiloli wezinto ezimbiwa phansi njengoba manje isikhiqizwa emhlabeni jikelele cishe amalitha ayizigidi eziyi-100 ngonyaka okuwu-0.1% nje wesamba sesamba sikaphethiloli wendiza osetshenziswa yimboni. I-IATA ilinganisela ukuthi ukutshalwa kwezimali okugqugquzelayo kungasiza ekukhuphuleni ukukhiqizwa kwe-SAF ku-2% (amalitha ayizigidi eziyizinkulungwane ezingu-6-7) okudingekayo ukuze kutholwe isiphetho esingaba khona ukuletha i-SAF emazingeni ancintisanayo amanani uma kuqhathaniswa nophethiloli.
I-SAF isanda kugqanyiswa embikweni wezimboni ezahlukene i-Waypoint 2050 yi-Air Transport Action Group njengendlela ebaluleke kakhulu yokufeza izinhloso zesimo sezulu zemboni yezokundiza. Lo mbiko uphinde waphawula amandla ezindiza ezisebenza ngogesi ne-hydrogen ekusebenzeni kwesimo sezulu sezindiza kodwa wathi izixazululo ezisebenzayo ezithengiswayo zisekude le minyaka eyishumi futhi zinikeza amandla amakhulu kakhulu ezindiza ezidonsa isikhathi esifushane. Ukusebenza okude kungenzeka kuhlale kuncike kumafutha awuketshezi isikhathi eside.
I-SAF iyisixazululo esikhethwa yimboni mayelana nezakhiwo zayo ezihlukile:
- I-SAF inomthelela. Phakathi nomjikelezo wayo wokuphila, i-SAF yehlisa ukukhishwa kwe-CO2 kufika ku-80%.
- I-SAF ubuchwepheshe obufakazelwe. I-SAF isetshenziswe ngokuphepha ezindizeni ezingaphezu kuka-300,000 kuze kube manje.
- I-SAF iyakala futhi isilungele ukusetshenziswa ezikhundleni zanamuhla. Azikho izinguquko zenjini ezidingekayo. Futhi ingaxutshwa ne-jet parafini njengoba izimpahla zanda.
- I-SAF inemibandela eqinile yokusimama. Yonke impahla eluhlaza (i-feedstock) esetshenziselwa ukukhiqiza i-SAF itholakala kuphela emithonjeni eqhubekayo. Njengamanje i-SAF ikhiqizwa ngemfucuza okuhlanganisa amafutha okupheka asesebenzile kanye nezitshalo ezingezona ukudla, kanti imfucuza kamasipala kanye negesi engasenagesi ingase ifakwe esitokweni maduze.
“Njengoba umhlaba ubheke ukufukula kabusha umnotho, masingamoshi leli thuba ukuze sidale amathuba omsebenzi nemboni ezoletha izinzuzo ezinkulu ukuze kusizakale umphakathi. Uma singehlisa amanani entengo ye-SAF njengoba sinyusa amanani okukhiqiza, sizokwazi ukuxhuma ngokuqhubekayo umhlaba we-post-COVID-19,” kusho u-de Juniac.
