ORNL researchers introduce poplar gene into switchgrass to allow for fungus interaction

ORNL researchers introduce poplar gene into switchgrass to allow for fungus interaction

October 5, 2021 |

In Tennessee, an Oak Ridge National Laboratory team has successfully introduced a poplar gene into switchgrass, an important biofuel source, that allows switchgrass to interact with a beneficial fungus, ultimately boosting the grass’s growth and viability in changing environments.  Scientists observed the ectomycorrhizal fungus Laccaria bicolor as it enveloped the plant’s roots. This behavior, not […]

ORNL researchers make breakthrough discovery of how genes function in plants

September 9, 2021 |

In Tennessee, for decades, biologists have believed a key enzyme in plants had one function—produce amino acids, which are vital to plant survival and also essential to human diets. But for researchers at the Oak Ridge National Laboratory, this enzyme does more than advertised. They had run a series of experiments on poplar plants that […]

ORNL researchers develop new catalyst to covert ethanol into C3+ olefins

ORNL researchers develop new catalyst to covert ethanol into C3+ olefins

August 2, 2021 |

In Tennessee, Oak Ridge National Laboratory researchers have developed a new catalyst for converting ethanol into C3+ olefins—the chemical building blocks for renewable jet fuel and diesel—that pushes the amount produced to a record-high 88%, a more than 10% gain over their previously developed catalyst.  In the search for new catalysts, researchers achieved the record […]

ORNL researchers discover single gene that can boost growth and stress tolerances

June 10, 2021 |

In Tennessee, researchers at Oak Ridge National Laboratory have discovered a single gene that simultaneously boosts plant growth and tolerance for stresses such as drought and salt, all while tackling the root cause of climate change by enabling plants to pull more carbon dioxide from the atmosphere.  As climate change triggers more frequent and longer-lasting […]

ORNL researchers make progress on ethanol-to jet-fuel

June 7, 2021 |

In Tennessee, in the first step of a multi-step ethanol-to-jet-fuel process developed by DOE’s Oak Ridge National Laboratory, a catalyst is used to convert ethanol into butene-rich C3+ olefins, important intermediates that can then be processed into aviation fuels. Two more steps—oligomerization and hydrotreating—convert these intermediates into the liquid hydrocarbons used as fuels. A team […]

NREL and ORNL researchers find sugar yields of lignocellulosic feedstocks key

NREL and ORNL researchers find sugar yields of lignocellulosic feedstocks key

November 4, 2020 |

In Colorado, popular wisdom holds that tall, fast-growing trees are best for biomass, but new research by two U.S. Department of Energy National Laboratories reveals the size of trees is only part of the equation. Of equal economic importance, according to scientists from the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) and Oak […]

Multifunctional microbe simplifies processing of plant-derived fuels, chemicals

September 20, 2020 |

In Tennessee, Oak Ridge National Laboratory scientists have modified a single microbe to simultaneously digest five of the most abundant components of lignocellulosic biomass. This is a big step forward in the development of a cost-effective biochemical conversion process to turn plants into renewable fuels and chemicals. With support from the U.S. Department of Energy […]

ORNL researchers use supercomputing to understand how organic solvent and water break down biomass

ORNL researchers use supercomputing to understand how organic solvent and water break down biomass

July 9, 2020 |

In Tennessee, scientists at the Department of Energy’s Oak Ridge National Laboratory used neutron scattering and supercomputing to better understand how an organic solvent and water work together to break down plant biomass, creating a pathway to significantly improve the production of renewable biofuels and bioproducts. The discovery, published in the Proceedings of the National […]
