PNNL researchers marry algae for biofuels with fighting viruses

PNNL researchers marry algae for biofuels with fighting viruses

September 15, 2021 |

In Washington state, when the coronavirus pandemic thrust the world into turmoil last year, a group of bioenergy researchers at Pacific Northwest National Laboratory (PNNL) saw an unconventional way to fight the pandemic: algae.  What followed was a deep dive into the literature linking algae and antivirals as far back as 1956. To make sense […]

Making methane from CO2: carbon capture grows more affordable

Making methane from CO2: carbon capture grows more affordable

September 12, 2021 |

In Washington, in their ongoing effort to make carbon capture more affordable, researchers at the Department of Energy’s Pacific Northwest National Laboratory have developed a method to convert captured carbon dioxide (CO2) into methane, the primary component of natural gas. By streamlining a longstanding process in which CO2 is converted to methane, the researchers’ new […]

New report identifies top 13 biomass blendstocks to reduce vehicle emissions

New report identifies top 13 biomass blendstocks to reduce vehicle emissions

August 22, 2021 |

In Washington, researchers from PNNL and the U.S. Department of Energy Co-Optima initiative identified the top 13 diesel fuel blendstocks from biomass resources that could reduce harmful emissions from medium- to heavy-duty diesel vehicles. The top 13 blendstocks include hydrocarbons, esters, and ethers that have the potential to reduce GHG emissions by at least 60% […]

PNNL researchers seek to produce fuel for remote Alaskan communities from kelp

PNNL researchers seek to produce fuel for remote Alaskan communities from kelp

August 3, 2021 |

In Alaska, kelp is plentiful in remote, coastal Alaska. Fuel is not. And it’s expensive. Many isolated communities rely on diesel generators for energy because they are not connected to pipelines or the electrical grid. But diesel is expensive since it must be barged or flown in. In search of a cheaper, sustainable fuel, researchers […]

PNNL researchers study plant material that offers clues for making sustainable bioproducts

PNNL researchers study plant material that offers clues for making sustainable bioproducts

August 1, 2021 |

In Washington, Pacific Northwest National Laboratory researchers are forming a clearer picture of how plant matter is transformed in the microbial gardens the ants create. This detailed understanding of how fungus degrades biomass could one day help scientists develop microbial systems for sustainable bioproduct production, such as biofuels or renewable chemicals. In the latest of […]

PNNL researchers find clingy copper ions contribute to catalyst slowdown

PNNL researchers find clingy copper ions contribute to catalyst slowdown

May 16, 2021 |

In Washington, scientists at Pacific Northwest National Laboratory, Washington State University and Tsinghua University, discovered a mechanism behind the decline in performance of an advanced copper-based catalyst. Spectroscopy revealed a deactivating force in catalysts used to reduce diesel emissions. Heavy-duty diesel trucks on the road today are equipped with aftertreatment systems that include selective catalytic […]

PNNL researchers produce dense biofuel from food waste

PNNL researchers produce dense biofuel from food waste

March 23, 2021 |

In Washington state, researchers from Pacific Northwest National Laboratory successfully converted food waste from Joint Base Lewis-McChord and Coyote Ridge Corrections Center into an energy-dense biofuel that could help replace today’s fossil fuels. Early results suggest food waste might deliver a trifecta of efficiency, economic and environmental benefits. First, from an efficiency standpoint, food waste’s […]
