For biodiesel to move into the mainstream, it obviously requires more vehicles that can burn the fuel along with increasing volumes of sustainable feedstock. But before that, it will take more fueling stations and a streamlined distribution infrastructure.

Biodiesel plants are starting to co-exist along side oil refineries. Magellan Midstream Partners announced its 10th plant to produce and pipeline biodiesel alongside of petroleum.

The new facility in Aurora, Colorado will be the 40th terminal nationwide carrying biodiesel according to the National Biodiesel Board. Most biodiesel is shipped by rail, but more distribution terminals and pipelines will be needed to reduce the cost and increase consumer access to biodiesel.

Announcements from the Detroit Auto will encourage more energy companies to get involved with biodiesel. Honda and Toyota -- both known for their success with hybrids -- will provide another fuel efficient option with diesel cars and trucks starting next year. This is a substantial shift for the companies, but to be continue their reputation as fuel efficiency leaders, they had no choice but to jump on board the diesel bandwagon.

Safeway this week promised to switch its entire fleet of trucks to biodiesel as part of the company's initiative to reduce its carbon footprint. When you consider the 20 percent increased efficiency of diesel engines along with only using 80 percent fossil fuels (with B20), the carbon impact is substantial.
