MIT study finds significant economic and environmental benefits from designing US LDVs to use higher octane gasoline (98 RON)

Green Car Congress

In a companion study to an SAE paper presented in April ( earlier post ), researchers at MIT have quantified the net economic and CO 2 emissions benefit that could be obtained by utilizing 98 RON gasoline in light-duty vehicles, based on reasonable assumptions for possible refinery changes and the evolution of the LDV fleet.

MIT study finds fuel economy standards are 6-14 times less cost effective than fuel tax for reducing gasoline use

Green Car Congress

In a study published in the journal Energy Economics , MIT researchers have found that a fuel economy standard is at least six to fourteen times less cost effective than a fuel tax when targeting an identical reduction in cumulative gasoline use (20% by 2050). —Karplus et al. Resources.

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

Green Car Congress

Using that data, the researchers modeled the costs for a fleet of 250 delivery trucks, and examined alternate scenarios in which the whole fleet used one of three kinds of motors: purely electric engines, hybrid gas-electric engines and conventional diesel engines. Firms do not need fleets as big as 250 trucks to realize savings.

MIT and IEA reports take different views of the future of natural gas in transportation

Green Car Congress

MIT and the IEA both have newly released reports exploring the potential for and impact of a major expansion in global usage of natural gas, given the current re-evaluation of global supplies. emissions are reduced by around 25% relative to the use of gasoline for the same engine efficiency. Earlier post.) Tcf/year, equivalent to 1.3

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.

Separate MIT, IEA reports both outline major expansion in role of natural gas; caution on climate benefits

Green Car Congress

” The MIT report said that natural gas should be seen as a “ bridge ” to a low-carbon regime, rather than as the ultimate long-term solution itself. MIT: The Future of Natural Gas. Separately, the International Energy Agency (IEA) released its own report exploring the potential for a “golden age” of gas. Source: IEA.

Study finds CO2 emissions trading more effective path to automotive CO2 reduction in Europe than tailpipe standards

Green Car Congress

Switching from the automotive standards to the trading scheme could save as much as €63 billion, says the study’s lead author Sergey Paltsev, deputy director at MIT’s Joint Program on the Science and Policy of Global Change and senior research scientist at the MIT Energy Initiative.
