DOE researchers investigate economic and environmental impacts of converting wet waste to renewable diesel

Green Car Congress

estimated that with conversion by hydrothermal liquefaction (HTL) and upgrading, the wet waste resource availability in the United States could be converted to jet fuel that is equivalent to about 24% of the U.S. Among their findings: The estimated minimum fuel selling prices were $1.22/gasoline Skaggs et al. demand in 2016.

EU project HyFlexFuel converted sewage sludge and other biomasses into kerosene by hydrothermal liquefaction (HTL); SAF

Green Car Congress

Biocrudes from three representative feedstocks—Spirulina (micro-algae), sewage sludge, and wheat straw—were further upgraded to a mixture of hydrocarbon fuels at Aalborg University (Denmark). Analyses of the kerosene fractions of the upgraded biocrude show promising compositions for a use as aviation fuel.

Penn team proposes liquid-organic hydrogen carriers as endothermic fuels for hypersonic aircraft

Green Car Congress

A team at the University of Pennsylvania is proposing the use of a liquid-organic hydrogen carrier (LOHC)—specifically, 1,2,3,4 -tetrahydroquinoline (THQ)—for use as an endothermic fuel for thermal protection of hypersonic aircraft engines. A paper on their work is published in the journal Fuel. —Cao et al.
