MIT team proposes SCR emission control for hybrid aviation turbines; reducing NOx by 95%

Green Car Congress

The trend towards smaller engine cores with smaller mass flow rates in the core stream, presents new opportunities for emissions control. SCR systems would reduce NO x emissions at the cost of increased aircraft weight and specific fuel consumption due to the pressure drop in the core stream induced by the catalyst.

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.

Argonne releases new cradle-to-grave lifecycle analysis of US LDV vehicle-fuel pathways

Green Car Congress

The study provides a comprehensive analysis of the cost and greenhouse gas (GHG) emissions of a variety of vehicle-fuel pathways; the levelized cost of driving (LCD); and the cost of avoided GHG emissions. It is hard to overstate the importance of the improvements in battery costs on this analysis.
