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.

There has been much discussion for over thirty years or more around the use of hydrogen fuel cells as an alternative to the internal combustion engine. Fuel cells had been promoted in some sectors as the best alternative to the internal combustion engine.

The SRI CTL plant design offers a lower CO 2 -emitting fuel then conventional diesel; a lifecycle analysis by SRI put conventional diesel at 389 gCO 2 /mile, conventional F-T coal-to-liquids diesel at 830 gCO 2 /mile; and the SRI synthetic fuel at 326 gCO 2 /mile (when using carbon-neutral electricity. Lifecycle GHG comparison.

Comparison of brake thermal efficiency and specific fuel consumption at rated power (ICOMIA Mode 5), hydrogen vs. gasoline engines. The lost available energy also results in poor off-design point fuel efficiency. ICOMIA cycle NO x emissions and hydrogen consumption, efficiency-optimized calibration. Oh and Plante.

Boeing and a team from across the aviation industry today released high-level elements of a study that shows that sustainable biofuels analyzed in a series of test flights performed favorably in comparison to petroleum-based fuel. The Bio-SPK process converts bio-derived oils (triglycerides and free fatty acids) to Bio-SPKs.

There is another option, though, in hydrogen fuel cell vehicles. How Hydrogen Can Power Cars. The Toyota Mirai is the best-selling hydrogen fuel cell vehicle. How does hydrogen work in the first place? Hydrogen fuelled cars have many similarities to BEVs that are on the road today.

There are two basic approaches to converting coal to synthetic fuels: indirect liquefaction (ICL) (Fischer-Tropsch) and direct (Bergius). The indirect liquefaction pathway first gasifies the coal to produce a syngas, and then catalytically converts the syngas to linear hydrocarbons or chemicals.
