| Source: Dynamic Fuels

WASHINGTON, Dec. 5, 2011 (GLOBE NEWSWIRE) -- Dynamic Fuels, LLC, a joint venture between Tyson Foods, Inc. (NYSE:TSN) and Syntroleum Corporation (Nasdaq:SYNM), has been awarded a contract to supply the U.S. Navy with 450,000 gallons of renewable fuels. Solazyme, Inc. (Nasdaq:SZYM), a renewable oil and bioproducts company, will help Dynamic Fuels fulfill the contract, which the Navy and the USDA report is the single largest purchase of biofuel in government history.

The contract involves supplying the Navy with 100,000 gallons of jet fuel (Hydro-treated Renewable JP- 5 or HRJ-5) and 350,000 gallons of marine distillate fuel (Hydro-Treated Renewable F-76 or HRD-76). The fuel will be used as part of the Navy's efforts to develop a "Green Strike Group" composed of vessels and ships powered by biofuel.   

The Navy contract follows on the heels of both companies' involvement in historic commercial airline flights using biofuel. This includes Dynamic Fuels' renewable jet fuel work with KLM Royal Dutch Airlines, Finnair, Thomson Airways and Alaska Airlines, and Solazyme's recent flight and partnership with United Airlines, which includes a letter of intent to provide 20 million gallons a year starting in 2014.

The fuel for the Navy will be manufactured at Dynamic Fuel's Geismar, Louisiana, renewable fuels plant using U.S.-sourced yellow grease (used cooking oil) as well as Solazyme's tailored algal oil as feedstocks. The fuel will be delivered to the U.S. Navy in May 2012. The Dynamic Fuels plant, which has been in operation for more than a year, is designed to convert non-food feedstocks such as algal oil, animal fats, and greases into renewable fuels.

"This award clearly demonstrates that we're building momentum for the sale and use of our renewable fuels," said Jeff Bigger, director of the Dynamic Fuels LLC Management Committee. "We've previously provided the U.S. military with fuel for testing. We believe this contract confirms they recognize the performance and environmental advantages of our fuel since they're coming back for more and are asking for a much larger volume."

"This is an historic contract and we are proud to be teaming up with Dynamic Fuels to produce and deliver the advanced biofuel to the U.S. Navy to sail the Great Green Fleet. Dynamic Fuels has been a leader in next generation advanced biofuels technology and this partnership further solidifies the progress that both of our companies are making in bringing advanced renewable fuels to commercialization," said Jonathan Wolfson, CEO, Solazyme. "Solazyme is honored to be working with the U.S. Navy and DLA-Energy in driving forward the Navy's effort under Secretary Ray Mabus to source 50 percent of its energy from renewable sources by 2020."
