Biodiesel

Unblended, 100% biodiesel (B100) is an alternative fuel made from renewable resources such as vegetable oils or animal fats. Using pure biodiesel (B100) — or even some high level biodiesel blends such as B20 (20% biodiesel) — in older diesel-powered vehicles not equipped with advanced emissions control technology can result in a reduction of particulate emissions. Biodiesel also:

Biodiesel Blends

Unblended, 100% biodiesel (B100) requires special handling and maintenance precautions as well as modifications to most engines in order to be used. Consequently, biodiesel is usually blended with petroleum-based diesel for ease of use. Most diesel vehicles today can run biodiesel blends up to 5% (B5) without voiding a vehicle manufacturer‘s warranty. Some engine manufacturers may allow biodiesel blends up to 20% (B20) to be used, but only under specific conditions. Before using biodiesel in your vehicle or equipment, always check your owner‘s manual or contact the manufacturer for guidance.

AC Transit‘s test fleet of biodiesel buses is using a B20 Biodiesel Blend, with the cooperation of the engine manufacturer, Cummins.

The Future of Biofuels

Testing and developing the market for biodiesel today will lead to higher quality, cleaner biodiesel tomorrow. Research is under way to explore ways to improve both the quality and the cost-competitiveness of renewable diesel. Further research is looking at developing renewable diesel that could be made from virtually any kind of plant fiber or biomass.
