U Chicago, MIT study suggests ongoing use of fossil fuels absent new carbon taxes

Green Car Congress

A paper by a team from the University of Chicago and MIT suggests that technology-driven cost reductions in fossil fuels will lead to the continued use of fossil fuels—oil, gas, and coal—unless governments pass new taxes on carbon emissions. for oil, 24% for coal, and 20% for natural gas.

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. Natural gas use in the transportation sector is likely to increase, with the primary benefit being reduced oil dependence.

Ford E85 Direct Injection Boosting Study: A Less Expensive Alternative to Diesel

Green Car Congress

Proposed by John Heywood and colleagues at MIT in 2005, the basic premise of E85 boosting is that ethanol (or other lower alcohols) suppresses knock due to the large evaporative cooling effect it has on the air-fuel mixture when injected directly into the cylinder, supplemented by ethanol’s inherent high octane number. Earlier post.)

MIT Researchers Find That Elastic Energy Storage Systems Built With Carbon Nanotubes Could Match Li-ion Battery Energy Densities

Green Car Congress

Densities for steel springs and Li-ion batteries provide a comparison. Any system that requires conversion from mechanical energy to electrical and back again, using a generator and then a motor, will lose some of its energy in the process through friction and other processes that produce waste heat.

New Study Finds Flaw in Carbon Accounting for Bioenergy, Another Contends That Indirect Land Use Change Emissions for Biofuels Will Be Up To Twice Direct Land Use Change Emissions

Green Car Congress

A separate paper published online in Science Express by researchers from the Marine Biological Laboratory, Woods Hole and MIT concludes that indirect land use change associated with global biofuels programs will be responsible for substantially more carbon loss (up to twice as much) than direct land use. issue of the journal Science.
