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.

Argonne study finds BEVs can have lowest scheduled maintenance costs, but highest cost of driving

Green Car Congress

The study considers five different powertrains (internal combustion engine, hybrid-electric, plug-in hybrid-electric, fuel-cell-electric, and battery-electric) and 12 cost components (purchase cost, depreciation, financing, fuel, insurance, maintenance, repair, taxes, registration fees, tolls and parking, payload capacity and labor).

European Strategy for low-emission mobility stresses digital tech, electrification and ZEVs

Green Car Congress

This would include some plug-in hybrids, full electric cars and hydrogen fuel cell vehicles. Through the Strategy, the Commission is looking into how to accelerate the use of low-emission alternative energy, such as advanced biofuels, electricity, hydrogen and renewable synthetic fuels by providing strong incentives to innovate.
