DENVER, May 17 -- Mayor John Hickenlooper will join Blue Sun Biodiesel on Wednesday, May 19, 2004, at 10:00 a.m., as they announce 10 new Colorado B20 biodiesel stations opening this month.

Biodiesel is the fastest growing alternative energy source in the United States because it is compatible with existing diesel vehicles and has an extraordinary energy balance of 3.2 units of energy created for every one unit of energy used in its production.

Blue Sun B20 (20% biodiesel, 80% diesel) is a premium diesel fuel that combines the superior lubricity and cetane of biodiesel with conventional diesel fuel and includes a proprietary additive that helps provide superior performance and quality assurance. Blue Sun Biodiesel is an agriculture energy company developing new industrial oilseed crop production and new state-of-the-art biodiesel production facilities, the first of which will create 240 new jobs and inject $45 million of new income annually into the region.

Currently, three Colorado biodiesel fueling sites exist at Bartkus Oil in Boulder, Shoco Oil in Commerce City, and Heartland Town and Country in Fort Morgan. The 10 new retail fueling sites that will be opening are at the following locations: Acorn Petroleum in Pueblo, Acorn Petroleum in Colorado Springs, Ampride 1 in Sterling, Brennen Oil in Durango, Catherine store in Carbondale, Cox Oil Company in Greeley, Offen Petroleum in Denver, LaSalle Oil in LaSalle, Poudre Valley CO-OP in Fort Collins, and a RTD fueling site in Boulder.
