ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Their open access paper is published in the journal Energy.

Simulation study suggests ORC waste heat recovery system could deliver potential 7% improvement in fuel consumption in a PHEV on highway

Green Car Congress

Starting from a energy-based powertrain simulation model validated on experimental data from the PHEV, the researchers conducted a first- and second-law analysis to identify the potential for engine waste heat recovery, considering a variety of driving cycles and assuming the vehicle operating in charge-sustaining (HEV) mode.

Bosch on importance of renewable synthetic fuels to reach climate goals; e-fuels

Green Car Congress

Electromobility is just now picking up momentum; further, electric cars are only as emissions-free as the production of electricity that charges their batteries. In addition, around half the vehicles that will be on the road in 2030 have already been sold—most with gasoline or diesel engines. Then add carbon.
