Navy researchers produce high energy density jet fuels from sustainable cellulosic feedstocks

Green Car Congress

Researchers from the Naval Air Warfare Center Weapons Division (NAWCWD) have developed an efficient three-step process for the conversion of cellulosic feedstocks to both a valuable chemical precursor and high-performance jet fuel blendstock. Their paper appears in the journal ChemSusChem. MJ/kg and 39.04 MJ/L (up to 17.7%

EPA Proposes to Streamline Approval Process for Fuel Conversion Systems

Green Car Congress

The US Environmental Protection Agency (EPA) is proposing to make it easier for manufacturers to gain approval to sell fuel conversion systems. The proposed rule would cover conversions of light-duty vehicles and heavy-duty highway vehicles and engines, and would apply to all clean alternative fuels. Vehicle/Engine Age.
