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. —Curran et al.

Rice flash Joule heating process recycles plastic from end-of-life F-150 trucks into high-value graphene for new vehicles

Green Car Congress

The Rice lab of chemist James Tour introduced flash Joule heating in 2020 to convert coal, petroleum coke and trash into graphene. The researchers cited a study that estimates the amount of plastic used in vehicles has increased by 75% in just the past six years as a means to reduce weight and increase fuel economy.
