Blue Sun shines in biodiesel fuel study

Blue Sun Biodiesel, which plans to open 12 new fueling stations this fall, got a major boost Wednesday when a federal study touted the benefits of its product.

A study by the National Renewable Energy Laboratory indicated that B20, a blend of 80 percent diesel and 20 percent treated vegetable oil, produced lower emissions of four major air pollutants in the Rocky Mountain region.

"In a 12-month study using Blue Sun's B20 biodiesel, NREL found nitrogen oxide was reduced by 5 percent compared to conventional diesel," Jeff Probst, president of Fort Collins- based Blue Sun, said during a news conference in downtown Denver.

Nitrogen oxide is a major source of ground-level ozone smog, an irritant often cited as a cause of chest pain, asthma and breathing difficulties.

Probst said NREL's study also indicated that B20 reduced carbon monoxide by 32 percent, hydrocarbons by 40 percent and particulate matter by 24 percent compared with diesel.

"This is good news for Denver and all cities working to clean up their air and reduce emissions," Denver Mayor John Hickenlooper said.

Hickenlooper pointed out that in the early 1990s, Denver was the first city to launch a "green fleet" of city vehicles. In March, Denver Public Schools announced that it would use Blue Sun B20 in 50 of its 450 school buses.

Addressing the conference, U.S. Sen. Ken Salazar, D-Colo., said fuels such as biodiesel, which can be used in diesel vehicles without any engine modification, would reduce America's dependence on foreign oil.

"With leading research universities, the National Renewable Energy Laboratory and private companies like Blue Sun working on developing alternative fuels, Colorado is poised to become an international leader in clean energy," Salazar said.
