Sustainable Aviation Fuels, with Zia Abdullah by Resources Radio published on 2022-08-09T13:51:14Z In this week’s episode, host Kristin Hayes talks with Zia Abdullah, a program manager at the US Department of Energy’s National Renewable Energy Laboratory. Abdullah and Hayes discuss what sustainable aviation fuels are made of, how they are refined and manufactured, and how they compare to traditional jet fuel. Abdullah also discusses the challenges in store for the United States in reaching the federal government’s sustainable aviation fuel production goals for 2030.

In addition, Abdullah fails to mention that combustion of SAFs at altitude will continue to emit NOx, SOx, particulates, and soot, all of which combine for greater climate change impact than aviation carbon emissions. Further, he fails to mention that NOBODY is talking about blending into jet fuel tanks anything more than 50% SAFs. Look who's behind the push for SAFs, and you'll understand that charges of "greenwashing" are not out of place. 2022-09-23T00:23:46Z
