The Seattle Times reported that Safeway has begun selling biodiesel in the Seattle area. Safeway's first pump opened in West Seattle with B20, a blend of 20 percent biodiesel from soy and 80% petroleum diesel fuel.

A large chain like Safeway offering biodiesel is proof that demand for biodiesel is on the rise. Safeway has the potential to significantly increase biodiesel distribution and availability to meet this demand. For many West Seattleites, Harbor Island or South Seattle were previously the closest fueling stations. If the fuel sells well, Safeway may open additional stations in Ballard and Crown Hill.

There are two main benefits of using biodiesel, even at lower concentrations such as B20. 1) Lubricity - Using even 1% biodiesel can improve the lubricity of diesel fuel by as much as 65%, lowering the wear and tear on the engine, and thus reducing maintenance costs. 2) Emissions - Biodiesel reduces most diesel engine emissions. Pure biodiesel, or B100, produced from soybean oil reduces carbon dioxide emissions by 78% compared to petroleum diesel. Lower blends will also decrease emissions of hydrocarbons, carbon monoxide, particulate matter, and harmful air toxics.

Biodiesel can be used in any diesel engine with little or no modifications. Mileage is about the same between both types of fuel, roughly 50 miles per gallon, as is the cost, about $2.78 for diesel and $2.86 for biodiesel. The EPA credit of 1% per percentage point of biodiesel per gallon (given every 450 gallons) can even out the additional cost.

Biodiesel is available in various blends at many pumps in the Seattle region. Check here for one near you.
