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).

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.

The Complex Calculus of Clean Energy and Zero Emissions

Cars That Think

—Jesse Jenkins, Princeton University When I entered the field, commercial wind was starting to scale up and the questions were about engineering feasibility. What was the maximum share of wind that we could have in the system without blowing it up—5 percent or 20 percent or 30 percent? So when I went to MIT to do my Ph.D.,

This Fusion Reactor Is Held Together With Tape

Cars That Think

Gretchen Ertl/CFS/MIT Plasma Science and Fusion Center CFS, a startup spun out of decades of research at the Massachusetts Institute of Technology (MIT), is among the leaders of a new wave of fusion-energy projects that have emerged in the past decade, taking advantage of technological advances as well as a surge in private-sector investment.

The Vacuum Tube’s Forgotten Rival

A second wire also wrapped around the core forms a control winding. The control winding includes many turns of wire, so by passing a relatively small direct current through it, the iron core can be forced into or out of saturation. After winding, the module was annealed in hydrogen at 1,100 °C for 2 hours and then rapidly cooled.

How EVs Are Reducing Carbon (CO2) Emissions

Blink Charging

As one MIT report found, on average, “a fully electric vehicle emits about 25 percent less carbon than a comparable hybrid car.” Finally, technology is also making EVs more eco-friendly, and as our energy grid switches to use more renewable sources like wind and solar power, EVs become even better for the environment.
