MIT study: half of US deaths related to air pollution are linked to out-of-state emissions

Green Car Congress

More than half of all air-quality-related early deaths in the United States are a result of emissions originating outside of the state in which those deaths occur, MIT researchers report in a paper in the journal Nature. —study leader Steven Barrett, an associate professor of aeronautics and astronautics at MIT.

MITEI study finds hydrogen-generated electricity is a cost-competitive candidate for backing up wind and solar

Green Car Congress

A team at MITEI (MIT Energy Initiative) has found that hydrogen-generated electricity can be a cost-competitive option for backing up wind and solar. California draws more than 20% of its electricity from solar and approximately 7% from wind, with more VRE coming online rapidly.

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 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. The first two reports dealt with nuclear power (2003) and coal (2007).
