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.

Study finds methane leaks from three large US natural gas fields in line with EPA estimates

Green Car Congress

CIRES is a partnership of NOAA and the University of Colorado Boulder. Where leak rates are low, the comparison favors natural gas. In the new study, the researchers also reported their findings by region: Methane emissions in the Marcellus region of northeastern Pennsylvania were about 16.5 tons (33,000 lbs) per hour, or 0.18-0.41%
