Scientists seeking to unravel the details of how plants produce and accumulate oil have identified a new essential component of the assembly line–a particular sterol that plays a key role in the formation of oil droplets. The findings may suggest new ways to engineer the oil content of a variety of plant tissues for potential applications in bioenergy, chemical engineering, and nutrition.
A new report led by PNNL identifies the top 13 most promising waste- and biomass-derived diesel blendstocks for reducing greenhouse gas emissions, other pollutants, and overall system costs.
Using existing fish processing plants, kelp and fish waste can be converted to a diesel-like fuel to power generators or fishing boats in remote, coastal Alaska.
A new wearable device turns the touch of a finger into a source of power for small electronics and sensors. Engineers at the University of California San Diego developed a thin, flexible strip that can be worn on a fingertip and generate small amounts of electricity when a person’s finger sweats or presses on it. What’s special about this sweat-fueled device is that it generates power even while the wearer is asleep or sitting still.
Research shows options with high yield and low water use
The U.S. Department of Energy (DOE) today awarded $45.5 million for research projects geared towards understanding and harnessing nature’s biological processes to produce clean biofuels and bioproducts.
Mary Dunlop leads a team at Boston University that uses multi-disciplinary approaches to improve the amount of biofuel that certain microbes can produce. These microbes can produce replacements for gasoline, diesel, and jet fuel.
Research highlights shrub willow’s ability to store carbon, provide ecosystem services, and adapt to different geographical regions.
A large-scale demonstration converting biocrude to renewable diesel fuel has passed a significant test, operating for more than 2,000 hours continuously without losing effectiveness.
Scientists have developed a novel catalyst that converts pure ethanol into a highly valued class of alcohols that can serve as building blocks for everything from solvents to jet fuel.
Micro- and nanoplastics were not absorbed by plant cells but did attach to the root cap. This could bode well for future cleanup of contaminated environments, but not well for root crops, like carrots.
PNNL researchers are contributing expertise and hydrothermal liquefaction technology to a project that intercepts toxic algae blooms from water, treats the water, and concentrates algae for transformation to biocrude.
PNNL researchers outline how to convert stranded biomass to sustainable fuel using electrochemical reduction reactions in mini-refineries powered by renewable energy.
The U.S. Department of Energy (DOE) awarded a five-year, $13 million grant to a nationwide research project to genetically strengthen Thlaspi arvense, commonly known as pennycress, for use in sustainable energy efforts.
Scientists do not fully understand the mechanisms that plants use to extract phosphorus from soil and incorporate it into their biomass. Now, researchers have developed a new technique to visualize the activity and distribution of enzymes that mobilize phosphate around plant roots.
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.
How can some of world’s biggest problems – climate change, food security and land degradation – be tackled simultaneously? Some lesser-known options, such as integrated water management and increasing the organic content of soil, have fewer trade-offs than many well-known options, such as planting trees, according to a Rutgers-led study in the journal Global Change Biology.
Berkeley Lab Science Snapshots July 2020
A new Quantitative Plant Science Initiative led by Brookhaven Lab aims to decode the functions of genes and their impacts on productivity to guide efforts to develop sustainable bioenergy crops.
Plants emit gases like methanol and acetic acid that are not directly related to photosynthesis but that have an unknown origin. Researchers have found a possible source: natural chemical modification in the cellulose in plant cell walls and accompanying metabolic changes.
Farmers have enough worries – between bad weather, rising costs, and shifting market demands – without having to stress about the carbon footprint of their operations. But now a new set of projects by scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) could make agriculture both more sustainable and more profitable.
Scientists at the Department of Energy’s Oak Ridge National Laboratory have developed a new method to peer deep into the nanostructure of biomaterials without damaging the sample. This novel technique can confirm structural features in starch, a carbohydrate important in biofuel production.
The nation’s biofuel producers have made significant gains in both energy efficiency and water conservation in recent years, according to a comprehensive survey conducted by Argonne National Laboratory.
Researchers will use a $2.25 federal grant to study how cells communicate within plants, and between plants and pathogens, to develop crops that are resilient to disease and other stresses. The work also could play a role in reengineering plants and microbes to improve biofuel production.
New research shows that the number of copies of genes in a poplar tree affects its traits. Scientists developed a group of poplar trees in which different plants have DNA segments that are repeated or deleted.
The U.S. Department of Energy has selected Danforth Center Principal Investigator James Umen, Ph.D., to lead a multi-institutional collaboration that will predict functions for hundreds of uncharacterized plant genes that could be important to stress tolerance in a range of potential bioenergy crops.
