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.

Waste gasification company Sierra Energy closes $33M Series A funding; FastOx

Green Car Congress

The funding will help Sierra Energy further develop and commercialize its FastOx gasification technology, which converts virtually any waste into clean, renewable energy and fuels without burning. Waste is fed into the top of the gasifier vessel through an airlock. Purified oxygen and steam are injected into the base.
