All SAF is not the same and using 100% SAF is a complex issue
Read my article in Greenairnews on 100% SAF and whether we will soon see use of 100% SAF in commercial flights https://www.greenairnews.com/?p=2460
Flying with 100% sustainable aviation fuels (SAF)
Airbus and Rolls Royce recently announced that they were testing 100% sustainable aviation fuels in flights. These flights will test the impact of 100% SAF on operability and emissions.Current ASTM D7566 certification allows the use of SAF in blends of 50% for most...
Biojet fuel technologies – Gasification with Fischer-Tropsch synthesis (Part I)
Gasification with Fischer-Tropsch (FT) synthesis was the first technology pathway that received ASTM certification for the production of biojet fuel in 2009. As yet, there is still no commercial production of biojet fuels using this technology and here we analyze the...
Why do we need biojet fuels?
Climate change due to human-induced emissions is a significant challenge and limiting and reducing emissions have become a global priority. The aviation sector accounts for approximately 2% of human-induced carbon dioxide emissions and 12% of emissions from...
