ICCT: US domestic airlines show modest improvement in fuel efficiency since 2010, top performers Alaska and Spirit widen lead

Green Car Congress

Alaska Airlines had the most efficient US domestic operations in both 2011 and 2012, the same position it occupied in a 2010 benchmark assessment published by the ICCT last year. Alaska is very efficient in large part because it operates a new Boeing fleet and uses turboprops on regional flights. Earlier post.) Click to enlarge.

US DOE to award up to $20M for research on methane hydrates

Green Car Congress

Selected projects will be intended to support program goals to determine the (1) likelihood of methane hydrates as a potential energy resource and (2) their role in the natural environment. A frequently quoted estimate of the global methane hydrate resource is 20,000 trillion cubic meters, or about 700,000 trillion cubic feet.

ConocoPhillips and US DOE project testing production of methane from hydrates via CO2 injection on Alaska North Slope

Green Car Congress

A fully instrumented well that will test innovative technologies for producing methane gas from hydrate deposits has been installed on the North Slope of Alaska. Researchers are addressing issues such as seafloor stability, drilling safety, and a range of environmental issues, including gas hydrate’s role in changing climates.

Global Ice Age Climate Patterns Influenced by Bering Strait

Green Car Congress

In a vivid example of how a small geographic feature may have far-reaching impacts on climate, new research shows that water levels in the Bering Straitβ€”which separates the US and Russia by only 90 kilometers (56 miles)β€”helped drive global climate patterns during ice age episodes dating back more than 100,000 years.
