Great Smoky Mountains National Park cuts emissions thanks to B20

September 7, 2017 |

In Tennessee, the Great Smoky Mountains National Park used 43,085 gallons of biodiesel (B20) in 2012 resulting in the following estimated emissions reductions: 15 percent reduction in carbon dioxide; 12 percent reduction in carbon monoxide; 20 percent reduction in both hydrocarbon and sulfur dioxide and 12 percent reduction in particulate matter. In keeping with its […]

ORNL researchers use old tires and UCO to produce biofuel

ORNL researchers use old tires and UCO to produce biofuel

August 2, 2017 |

In Tennessee, using a novel, reusable carbon material derived from old rubber tires, an Oak Ridge National Laboratory-led research team has developed a simple method to convert used cooking oil into biofuel. The team’s approach combines modified, recovered carbon with sulfuric acids, which is then mixed with free fatty acids in household vegetable oil to […]

ORNL researchers discover new class of porous membranes boosting biofuel production efficiencies

ORNL researchers discover new class of porous membranes boosting biofuel production efficiencies

July 25, 2017 |

In Tennessee, researchers at Oak Ridge National Laboratory set out to determine what could increase production speeds and improve the quality of biofuels and bioproducts. What they discovered is a new class of porous membranes—a high performance architecture surface-selective (HIPAS) membrane technology. Supported by the U.S. Department of Energy’s Bioenergy Technologies Office, this new class […]

ORNL using microbial process to produce hydrogen from biofuel processing wastewater

ORNL using microbial process to produce hydrogen from biofuel processing wastewater

May 10, 2017 |

In Tennessee, “electrical” bacteria are the key ingredient in a new process developed by the Department of Energy’s Oak Ridge National Laboratory that recycles wastewater from biofuel production to generate hydrogen. The hydrogen can then be used to convert bio-oil into higher grade liquid fuels such as gasoline or diesel. The team’s lab-scale demonstration can […]

Oak Ridge researchers discover metabolic and genetic reasons why some plants are drought tolerant

Oak Ridge researchers discover metabolic and genetic reasons why some plants are drought tolerant

January 5, 2017 |

In Tennessee, some semi-arid plants use a specific type of photosynthesis known as crassulacean acid metabolism, or CAM, to conserve water and flourish in semi-arid climates. Now scientists at the Department of Energy’s Oak Ridge National Laboratory have discovered the metabolic and genetic underpinnings that allow plants, such as the agave plant, to do so. […]

Gas station biodiesel storage tank leak likely culprit for fishkill in Tennessee

Gas station biodiesel storage tank leak likely culprit for fishkill in Tennessee

December 5, 2016 |

In Tennessee, a storage tank at a gas station in northern Scott County is expected to be the source of up to 5,000 gallons of biodiesel that has leaked into a nearby creek, leading to at least 2,000 dead fish. The state’s department of natural resources is investigating the spill and hopes to have an […]
