I-GTL ngemva kweminyaka eminingi yokutshalwa kwezimali, ucwaningo lwezobuchwepheshe kanye nokuqongelela isipiliyoni sokuzijwayeza, okwamanje, isikhungo socwaningo nentuthuko sesenze uhlelo oluphelele lokuthuthukiswa kobuchwepheshe, sinabasebenzi abanolwazi, abasezingeni eliphezulu, sinokuthuthuka okuqinile okuzimele, ukuthuthukiswa kanye nokukhiqiza amandla okucubungula, okuhola imboni emkhakheni othize wekhono eliqhubekayo lokuqamba izinto ezintsha.Ukuthuthukiswa okuqhubekayo kanye nokusungulwa kwezixazululo zohlelo lokusebenza, ngezikhathi ezihlukahlukene zohlelo lokusebenza ukunikeza amandla aqhubekayo ekhwalithi ephezulu, ukuthuthukisa umklamo womuntu, ukulungisa nokugcinwa kulula futhi kuyashesha.Imikhiqizo ithunyelwe e-Asia, eYurophu, e-Afrika, eNingizimu Melika nakwamanye amazwe nezifunda ezingaphezu kuka-40.
Ithimba layo lemikhakha eminingi yonjiniyela abaqeqesheke kakhulu lenza igalelo eliqhubekayo ekuthuthukiseni izingxenye zamasethi ejeneretha, kusukela ekwakhiweni kwezimboni kanye nesakhiwo sengxenye kuya ekwelapheni izinto ezisetshenziswayo kanye nezinqubo ezikhiqizayo, ukuze kuthuthukiswe ukusebenza, kube lula ukwenza isiqandisi nokwandisa izinga ukuvikela umsindo.
Ngenxa yalokhu, izinjini zingasebenza ngaphansi kwezimo ezikahle njengoba lokhu kuthuthukiswa kwenza kube lula ukuvutha, ukunciphisa igesi, ukushisa nomsindo okhishwayo, futhi kwandise impilo yokusebenza yamasethi e-generator.
Mayelana namaphaneli okulawula akhiqizwa yi-GTL, ukucushwa ngakunye kusebenzisa izingxenye ezisezingeni eliphezulu futhi kudlule ekulawuleni ikhwalithi ngokuqinile.I-GTL inganikeza imodi yokusebenza ehlukile ngokuya ngesidingo sekhasimende, njengokwenza ijeneretha ibe kwimodi yesiqhingi noma ngokufana kwenethiwekhi, noma yandise okunye ukusebenza.
