Company Fleets Going Biodiesel BY HOLLIS ALLEN ENTERPRISE FLEET MANAGEMENT BIODIESEL IS A CLEAN-BURNING ALTERNATIVE FUEL, pro- duced from domestic, renewable resources such as plant oils, animal fats, used cooking oil and even new sources such as algae. Designed for use in diesel engines, with different properties and benefits, biodiesel is distinctly different from ethanol, which is a renewable biofuel made primarily from corn and intended for use in gasoline-powered vehicles such as cars. Although it can be used alone, biodiesel is usually blended with diesel fuel according to strict industry specifications approved by the Environmental Protection Agency (EPA). The most common blends are 5 percent biodiesel/95 percent petroleum diesel, known as B5; and 20 percent biodiesel/80 percent petroleum diesel, known as B20. Biodiesel is legal for use at any blend level in both highway and non-road diesel vehicles. Most companies that switch to biodiesel are driven primarily by a sense of corporate responsibility and environmental stewardship. In addition to reducing reliance on fossil fuels and depleting our supply the benefits of biodiesel include reducing emissions of: carbon; particulate matter, which has been shown to be a human health hazard; and hydrocarbons, which contribute to the localized formation of smog. Although no new equipment or equipment modifications are necessary, switching to biofuels requires some advance preparation: • B20 biodiesel fuel can be stored in existing diesel fuel tanks and pumped with diesel equipment. However, companies with their own tanks must clean them to remove sediment and water. Guidelines include checking for water and draining regularly if needed and monitoring for microbial growth, treating with biocides as recommended by the biocide manufacturer. • When used for the fi rst time, because of its superior cleaning capability, biodiesel can release deposits accumulated on tank walls and fuel lines from previous diesel fuel, causing the fuel fi lter to clog. Therefore, the fuel fi lter should be changed after the fi rst tank of biodiesel has been used. Over the long term, the cleaning properties of biodiesel will keep the fuel tank and fuel system cleaner. • In very cold weather, particularly northern climates, biodiesel can cloud up. Therefore lower blends of biodiesel are recommended to avoid starting and drivability problems, such as B5 instead of B20. Local area fuel providers are the best resource for this information. • Companies considering the use of biodiesel should consult their vehicle manufacturer’s recommendations because of changes to some service intervals such as oil changes, fuel fi lter replacements, diesel particulate fi lter (DPF) regeneration, and others. Hundreds of fleets use biodiesel coast to coast. A guide for fleet managers created by the National Biodiesel Board (NBB) and available at includes locations of distributors and retailers in the U.S., handling and use guidelines, warranties and OEM standards, fuel quality and performance troubleshooting, user testimonials and links to additional resources and tips. The NBB is the national trade association of the biodiesel industry and the coordinating body for biodiesel research and development in the U.S. Enterprise Holdings, the parent company of Enterprise Fleet Management, began using biodiesel in 2010 for its fleet of airport shuttle buses and intends to have its entire airport shuttles converted to biodiesel by 2015. This includes more than 600 buses serving Alamo Rent A Car, Enterprise Rent-A-Car and National Car Rental across more than 50 North American markets. In addition to embracing biodiesel and other alternative fuels as they become commercially viable, Enterprise Holdings provides strong support for leading-edge renewable fuels research. ◆ Hollis Allen is the manager of Enterprise Fleet Management’s National Service Department and works with Enterprise’s team of veteran mechanics and accredited Automotive Service Excellence (ASE) technicians to serve the fleet maintenance needs of businesses with mid-size fleets.
