Rice University Study and Policy Paper Find US Biofuels Policies Flawed, Recommend Fundamental Overhaul

Green Car Congress

They also question whether mandated volumes for biofuels—including advanced biofuels—can be met and whether biofuels are improving the environment or energy security. Key findings of the report include: Environmental and Health Impacts. Therefore, we do not recommend renewing blenders’ credits when they expire at the end of 2009.

Devil in the Details: World Leaders Scramble To Salvage and Shape Copenhagens UNFCCC Climate Summit

Green Car Congress

The 15 th Congress, also known as the 15 th Conference of Parties, or COP 15, was initially intended to be a largely procedural summit, with many major negotiating points settled and most environmental ministers prepared to sign a binding emissions treaty that contained specific emissions targets as well as commitments to financing structures.

National Research Council report finds it unlikely the US will meet cellulosic biofuel mandates absent major innovation or a change in policies

Green Car Congress

In 2005, Congress enacted the Renewable Fuel Standard as part of the Energy Policy Act (EPAct) and amended it in the 2007 Energy Independence and Security Act (EISA). Resolving most of the barriers is necessary to achieving RFS2, and many of them are interrelated as illustrated by the examples below.

US and Japan successfully complete Arctic field trial of gas hydrate production technology using CO2-methane exchange within structure

Green Car Congress

The prior longest-duration field test of methane hydrate extraction via depressurization was six days (Japan-Canada 2007/2008 Mallik well testing program). The team injected a mixture of carbon dioxide (CO 2 ) and nitrogen into the formation, and demonstrated that this mixture could promote the production of natural gas.

3 winners of DOE’s “America’s Next Top Energy Innovator” Challenge: hydrogen-assisted lean-burn engines, graphene for Li-air and -sulfur batteries, and titanium process

Green Car Congress

One negative side effect of a lean burn engine, whether powered by gasoline or diesel fuel, is an increase in the amount of emissions released to the environment. The introduction of hydrogen into the engine virtually eliminates fuel emissions while greatly reducing the emissions of hydrocarbons and carbon monoxide.

Devil In The Details: Is Copenhagens 2 ºC Guardrail Obsolete?

Green Car Congress

A maximum concentration of 450 ppm carbon dioxide (~550 ppm CO 2 equivalent) in the Earth’s atmosphere is commonly cited as the limit at which average temperatures can be held at 2 ºC, and many emissions reduction proposals are based upon these two “upper bounds” targets. ºF) above pre-industrial temperatures.
