AvWeb this morning reports on a “highly cost-effective” way to make jet biofuel from renewable materials.  According to AvWeb, San Francisco-based, “AliphaJet said its catalytic method uses materials derived from plants and animals such as triglycerides and fatty acids.  ‘Our strategy fundamentally improves the economics of making 100-percent drop-in renewable jet biofuel,’ said Jack Oswald, CEO of AliphaJet. ‘Our approach is radically different and unlocks a new industry that can meet the U.S. Navy’s goal of replacing 50 percent of its liquid fuels with renewables by 2020.’ “AliphaJet said its catalytic de-oxygenation process ‘significantly reduces capital and operating costs’ because it does not require the use of hydrogen in processing. That means the processing plant can be less complex, reducing …
