Recent disputes among the many national and regional  players in the emerging biofuel/jet fuel markets may slow acceptance and  development of  hese promising alternatives to fossil fuels. The European Union’s emissions trading system (ETS) seems to be central to contentions by China and the United States.  The scheme would impose caps on carbon emissions from airlines flying into Europe, unleashing charges from China that the proposed rules discriminate against carriers from developing countries.

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 …
