MIT study finds real-world NOx from diesels cars in Europe greatly exceeds laboratory levels; transboundary emissions cause 70% of health impacts

Green Car Congress

A new study by MIT researchers, published this month in Atmospheric Environment , finds that in Europe, 10 major auto manufacturers produced diesel cars, sold between 2000 and 2015, that generate up to 16 times more NO x emissions on the road than in regulatory tests—a level that exceeds European limits but does not violate any EU laws.

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

Green Car Congress

Now, MIT engineers are proposing using an ammonia-based selective catalytic reduction (SCR) system that could result in an approximately 95% reduction in NO x emissions in exchange for a ~0.5% —Steven Barrett, professor of aeronautics and astronautics at MIT and corresponding author. increase in block fuel burn.

MIT team engineers yeast to be more tolerant to toxic byproducts, boosting biofuels production; “tolerance module”

Green Car Congress

To try to expand biofuels’ potential impact, a team of MIT engineers has now found a way to expand the use of a wider range of nonfood feedstocks to produce such fuels. The MIT researchers developed a way to circumvent that toxicity, making it feasible to use those sources, which are much more plentiful, to produce biofuels.

MIT study concludes V2G-enabled electric commercial trucks could offer lower total operating cost than conventional diesel fleet

Green Car Congress

A new study by researchers at MIT’s Center for Transportation and Logistics (CTL), concludes that electric commercial vehicles can cost 9 to 12% less to operate than trucks powered by diesel engines when used to make deliveries on an everyday basis in big cities and when V2G (vehicle-to-grid) revenue is incorporated.
