The synthetic diesel and jet fuels that we will produce are produced using the Fischer Trospch process, and are commonly referred to as FT Diesel, GTL diesel, or FT-SPK (FT jet fuel).
There are hundreds of thousands of Barrels Per Day of FT fuels in production and use worldwide. FT fuels have seen widespread commercial use since the 1970s, with well in excess of 1,500,000,000 billion barrels produced and used in that time. There are millions of miles of real-world road testing that have been performed, demonstrating the superior quality and performance of FT fuels.
These are true drop-in replacement fuels, delivering the same performance, in the same engines, through the same fueling infrastructure, with no modifications necessary, and no compatibility issues, at the same price as the conventional diesel and jet fuels that they are replacing.
Fisher Tropsch fuels feature extremely low levels of impurities such as sulfur and aromatics. They also have a very high cetane number (a measure of combustion quality).
FT fuels have demonstrated excellent cold-flow performance in both terrestrial and aviation applications.
Testing has demonstrated no issues with injector fouling, in both very hot and cold environments.
Long-term tests have shown superior performance in soot and metals loading in engine oil.
In aviation applications, the lack of soot in the exhaust post-combustion (see the yellow flame of conventional fuel vs the blue flame of the synthetic fuel above) results in lower heat radiation to engine components, delivering significant reductions in operating temperatures of the engines. This delivers very material benefits to engine longevity, particularly in high performance applications such as military aircraft.
Lower weight compared to conventional jet fuel also delivers advantages to payload and range.
