Carbon emissions from generating electricity for electric vehicles vary greatly across the individual US states

Green Car Congress

by Michael Sivak, Sivak Applied Research The overall advantage of battery electric over gasoline vehicles, in terms of well-to-wheels emissions of greenhouse gases, has been well documented. However, the emissions of electric vehicles depend greatly on the energy source used to generate the electricity that powers them. Natural gas 87.9

KAUST researchers show blending ammonia with DME yields low-carbon fuel with combustion properties similar to gasoline

Green Car Congress

Blending ammonia with a small amount of dimethyl ether (DME) gives a liquid fuel with low-temperature combustion properties very similar to gasoline, researchers at KAUST have shown. The development of such fuels could provide an option—in addition to electric cars—for “clean” power for the transportation sector.

MTU carbonate-superstructured solid fuel cell (CSSFC) delivers enhanced power density at lower operating temperatures

Green Car Congress

Solid oxide fuel cells (SOFCs) offer high energy efficiency and fuel flexibility, but require high operating temperatures. The CSSFC shows enhanced power density with hydrocarbon fuels at lower operating temperatures. such a carbonate superstructure on solid ionic conductor would be an oxygen ionic superconductor.
