Innovative Technologies: Transportation Fuels on the Table

Converting Biogas to Transportation Fuels

Concerns about depletion of fossil fuels and energy security have increased interest in renewable energy sources. Biogas, generated from anaerobic digestion of organic wastes, has a relatively low cost and is considered to be a renewable energy carrier. There is an increasing interest in converting biogas to “green” transportation fuels. This fact sheet discusses the technologies that are curre...

Biodistillate Transportation Fuels 2. – Emissions Impacts

Diesel vehicles are significant sources of NOx and PM emissions, and to a lesser extent, emissions of CO, HC, and toxic species. For many years, biodiesel fuel (and blends of biodiesel) has been promoted as a “clean fuel” alternative to conventional diesel. Based upon previous reviews by EPA, a common understanding has arisen that biodiesel usage reduces CO, HC, and PM emissions significantly, ...

Biodistillate Transportation Fuels 3 – Life Cycle Impacts

Life-cycle assessments (LCA) of biodistillate fuels are becoming increasingly important for policy decisions regarding alternative fuels. However, due to the dataintensive and assumptive nature of LCAs, rarely do two different studies produce comparable results. To add to the complexity, effects of indirect land use changes are now being incorporated into LCA models. This development is influen...

Biodistillate Transportation Fuels 1. Production and Properties

Biodistillate transportation fuels include biodiesel (produced via transesterification of animal fats and vegetable oils) and renewable diesel (produced via catalytic hydroprocessing of the same feedstocks). Production and use of biodistillates are increasing dramatically, both in the U.S. and globally. This paper describes the policy drivers prompting growth of biodistillate fuels in the U.S.,...
