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% This would be many, many times more feasible than what has been proposed for all-electric aircraft. increase in block fuel burn.

MIT team proposes flex-fuel gasoline-alcohol engine PHEV long-haul trucks

Green Car Congress

In a paper being presented at WCX SAE World Congress Experience in Detroit this week, a team from MIT is proposing the use of a flex-fuel gasoline-alcohol engine approach for a series-hybrid powertrain for long-haul Class 8 trucks. We think that the way to enable the use of electricity in these vehicles is with a plug-in hybrid.

MIT study finds air quality co-benefits of US carbon policies can significantly offset costs, depending upon the policy

Green Car Congress

The human health benefits associated with improvements in air quality related to the reduction in greenhouse gas emissions improvements can offset 26–1,050% of the cost of US carbon policies, depending upon the type of policy, according to a new study by a team from MIT. precursors through 2030. —Noelle Selin, co-author.

Maugeri: Natural Gas to Become #1 Electricity Source for This Century

Green Car Congress

Natural gas may soon be the dominant fuel for producing electricity, according to Leonardo Maugeri, senior executive vice president of Eni S.p.A, a leading energy company and a founding member of the MIT Energy Initiative (MITEI). Some of that water may surface as a pollutant, causing its own set of environmental problems.

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

Green Car Congress

World primary energy demand by fuel in the IEA high gas scenario. Separately, the International Energy Agency (IEA) released its own report exploring the potential for a “golden age” of gas. Both reports also emphasized that although natural gas is the lowest carbon fossil fuel, it is still a fossil fuel. Source: IEA.

MIT Report Finds Natural Gas Has Significant Potential to Displace Coal, Reducing Greenhouse Gas Emissions; Role in Transportation More Limited

Green Car Congress

Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT.
