Kuqale ukwenziwa kocwaningo lokukhishwa kukaphethiloli olusimeme olungu-100% lwendiza yabagibeli

• Iphrojekthi yokuqala ethi 'Emission and Climate Impact of Alternative Fuels' (ECLIF3) yethulwe
• Ucwaningo luzokwenziwa kusetshenziswa indiza ye-Airbus A350-900 exhaswe yizinjini zeRolls-Royce Trent XWB
• Ukuhlolwa kwenjini yokususa uphethiloli kuqale ezikhungweni ze-Airbus eToulouse, eFrance, kuleli sonto

Ithimba longoti bezemkhathi lethule ucwaningo lokuqala emhlabeni mayelana nokukhipha umoya endizeni lisebenzisa u-100% uphethiloli oqhubekayo wendiza (SAF) endizeni ethwala abantu abaningi.

Airbus, Isikhungo socwaningo saseJalimane i-DLR, i-Rolls-Royce kanye nomkhiqizi we-SAF u-Neste bahlanganyele ukuze baqale iphrojekthi yokuqala 'Yokukhishwa Nomphumela Wesimo Sezulu Wamanye Amafutha Asetshenziswayo' (ECLIF3) bebheka imiphumela ye-100% SAF ekukhishweni kwezindiza nokusebenza.

Okutholwe ocwaningweni - oluzokwenziwa phansi nasemoyeni kusetshenziswa indiza ye-Airbus A350-900 exhaswe yizinjini ze-Rolls-Royce Trent XWB - kuzosekela imizamo eqhubekayo e-Airbus naseRolls-Royce yokuqinisekisa ukuthi umkhakha wezokundiza ulungile. ukuze kusetshenziswe i-SAF ngezinga elikhulu njengengxenye yohlelo olubanzi lokuqeda ikhabhoni embonini. 

Ukuhlolwa kwenjini yokususa uphethiloli, okuhlanganisa nendiza yokuqala yokuhlola ukuhambisana kokusebenza kokusebenzisa i-100% SAF nezinhlelo zendiza, kuqale ezikhungweni ze-Airbus e-Toulouse, eFrance, kuleli sonto. Lokhu kuzolandelwa uhlolo olusha lwe-air-air-emissions okumele luqale ngo-April luphinde luqale eNkwindla, kusetshenziswa 'indiza yokujaha' ye-DLR's Falcon 20-E ukwenza izilinganiso kuphenywe umthelela we-SAF. Khonamanjalo, ezinye izivivinyo ezilinganisa ukukhishwa kwezinhlayiyana zisethelwe ukukhombisa umthelela wemvelo wokusetshenziswa kwe-SAF ekusebenzeni kwesikhumulo sezindiza. 

Kokubili ukuhlolwa kwendiza kanye naphansi kuzoqhathanisa ukukhishwa okuvela ekusetshenzisweni kwe-100% ye-SAF ekhiqizwe ngobuchwepheshe be-HEFA (i-hydroprocessed esters kanye nama-fatty acids) ngokumelene naleyo evela kuphalafini wezinsalela kanye nophalafini wezinsalela zesulphur ephansi. 

I-SAF izohlinzekwa ngabakwa-Neste, umphakeli ohamba phambili emhlabeni wonke wamafutha aqhubekayo endiza. Isilinganiso esengeziwe nokuhlaziywa kokuchazwa kokukhishwa kwe-particle-matter ngesikhathi sokuhlolwa okuphansi kuzolethwa yi-UK's University of Manchester kanye noMkhandlu Kazwelonke Wocwaningo waseCanada.

“I-SAF iyingxenye ebalulekile yesifiso se-Airbus sokuqeda ikhabhoni embonini yezindiza futhi sisebenzisana eduze nedlanzana lozakwethu ukuze siqinisekise ikusasa elisimeme lokuhamba ngendiza,” kusho uSteven Le Moing, uMphathi Wohlelo Lwezamandla Elisha, i-Airbus. “Izindiza okwamanje zingasebenza kuphela zisebenzisa isilinganiso esiphezulu esingu-50% sengxube ye-SAF kanye nezinsalela zikaphalafini; lokhu kubambisana okujabulisayo ngeke nje kunikeze ukuqonda kokuthi izinjini ze-gas-turbine zisebenza kanjani zisebenzisa i-100% ye-SAF ngenhloso yokuthola izitifiketi, kodwa zihlonze ukuncipha okungase kube khona kanye nezinzuzo zemvelo zokusebenzisa amafutha anjalo endizeni futhi.

UDkt Patrick Le Clercq, oyiMenenja yeProjekthi ye-ECLIF kwa-DLR, uthe: “Ngokuphenya u-100% we-SAF, silubeka kwelinye izinga ucwaningo lwethu ngokuklanywa kukaphethiloli kanye nomthelela wesimo sezulu sezindiza. Emikhankasweni yocwaningo yangaphambilini, besesivele sikwazile ukukhombisa amandla okunciphisa umule phakathi kuka-30 no-50% wengxube yezinye izinto zokubasa, futhi sithemba ukuthi lo mkhankaso omusha uzobonisa ukuthi leli khono manje likhulu nakakhulu.

“I-DLR isivele yenze ucwaningo olunzulu ngezibalo nokumodela kanye nokwenza izivivinyo zaphansi nezindiza kusetshenziswa ezinye izinto ezibaswayo ngendiza yocwaningo ye-Airbus A320 ATRA ngo-2015 nango-2018 kanye neNASA.” USimon Burr, Umqondisi Wokuthuthukiswa Komkhiqizo Nobuchwepheshe, Rolls- Royce Civil Aerospace, wengeze wathi: “Emhlabeni wethu wangemva kwe-COVID-19, abantu bazofuna ukuphinde baxhumane kodwa bakwenze lokho ngokuzinzile. Ngokuhamba amabanga amade, siyazi ukuthi lokhu kuzobandakanya ukusetshenziswa kwezinjini zegesi emashumini eminyaka ezayo. I-SAF ibalulekile ekuqedeni ikhabhoni yalolo hambo futhi sikweseka ngenkuthalo ukuthuthukiswa kokutholakala kwayo embonini yezokundiza. Lolu cwaningo lubalulekile ukuze sisekele ukuzibophezela kwethu ekuqondeni nasekuvumeleni ukusetshenziswa kwe-100% SAF njengesixazululo esikhipha umoya omncane.”
