Gaining new insight into how efficiently the microbes in large bioreactors produce methane from brewery waste, Cornell scientists hope to use their new knowledge to shape these microbial communities to produce liquid biofuels and other useful products.
Bioethanol from new lines of native perennial prairie grass could become less costly because of plant engineering by The Samuel Roberts Noble Foundation and fermentation research at Oak Ridge National Laboratory.
Graduate students pursuing careers in energy, policy, science and environmental matters are being encouraged to submit applications for Technology and Policy Tools for Energy in an Uncertain World, a week-long summer institute at Sandia National Laboratories in Livermore, Calif. The program will take place Aug. 7-12 and is open to U.S. citizens and foreign nationals.
Research Yields New Way to Create Poly-Silicon as Competitor for Fossil Fuel Energy; Discovery to Cut Cost of Solar-Cell Production
An engineering professor has developed a process for converting amorphous silicon into large-grain poly-crystalline silicon, which will decrease the cost of solar electricity to compete with fossil fuels.
Second phase of a study commissioned by the DOE Industrial Technologies Program (ITP), funded through Oak Ridge National Laboratory and convened by TMS will be used to formulate a core MSE development portfolio focused on meeting current and future energy challenges, while also opening opportunities for job creation and economic growth.
Researchers at the Department of Energy's Oak Ridge National Laboratory have developed a biohybrid photoconversion system -- based on the interaction of photosynthetic plant proteins with synthetic polymers -- that can convert visible light into hydrogen fuel.
Scientists analyzed five classical long term experiments using a process-based carbon balance model. They simulated experiments to predict the potential of no tillage management to maintain soil organic carbon.
The first rough draft of a "genetic road map" of the biomass crop, prairie cordgrass, is giving scientists an inside look at the genes of one of the crops that may help produce the next generation of biofuels.
Pine's fresh scent has helped scientists find missing sources of organic molecules in the air -- which, it might turn out, aren't missing after all. In work appearing in this week's PNAS Online, researchers found that particles containing compounds such as those given off by pine trees evaporate more than 100 times slower than expected by current air-quality models.
For more efficient power generation, operators of large wind farms should space their turbines farther apart.
TM-DOE report shows material science advances could improve performance and lower costs of electrical energy storage devices for the future electrical grid.
A straightforward new way to calculate, compile, and graphically present solar radiation measurements in a format that is accessible to decision makers and the general public has been developed by researchers at the University of Texas at Austin and is described in the Journal of Renewable and Sustainable Energy.
High energy costs are one drawback of making clean water from waste effluents. According to an article in the journal Biomicrofluidics, a new system that combines two different technologies proposes to break down contaminants using the cheapest possible energy source, sunlight.
The South could pay less for its electricity in 20 years than is currently projected if strong public policies are enacted to spur renewable energy production and use, according to a report released today by researchers at the Georgia Institute of Technology and Duke University.
An effort to increase biofuel production has led scientists to discover genes in yeast that improve their tolerance to ethanol, allowing the production of more ethanol from the same amount of nutrients. This study shows how genetically altered yeast cells survive higher ethanol concentrations, addressing a bottleneck in the production of ethanol from cellulosic material (nonfood plant sources) in quantities that could compete economically with fossil fuels.
The cyanobacteria are famous for releasing the oxygen that made Earth the hospitable planet we know today, but some strains also have hidden talent for producing hydrogen gas. Washington University in St. Louis currently holds the gas-producing record for these versatile microbes.
A USC Marshall MBA research team finds that global investment is being restricted by a range of factors, from policy to affordability.
Realtime view of single nanowire anode offers information to improve lithium batteries.
As the U.S. policy makers renew emphasis on the use of nuclear energy in their efforts to reduce the country's oil dependence, other factors come into play. One concern of paramount importance is the seismic hazard at the site where nuclear reactors are located.
Mirroring an approach that Indiana has taken to the life sciences industry, the state's economic development efforts could capitalize on existing clusters of wind energy and automotive-related companies to foster a more sustainable and profitable business environment. That's the lead finding by a panel of second-year MBA students at Indiana University's Kelley School of Business, who were asked to participate in a competitive project for the INdiana Sustainability Alliance (INSA).
A University of Arkansas researcher and his colleagues have created the first methane-producing microorganism that can metabolize complex carbon structures, which could lead to microbial recycling of waste products and their transformation into natural gas.
Researchers from Iowa State University and the Ames Laboratory have developed a process for fabricating more efficient polymer solar cells. The result is a polymer solar cell that captures more light and produces more power.
Microbiologists Derek Lovley, Zarath Summers and colleagues report in the Dec. 2 issue of Science that they've discovered a surprising new cooperative behavior in bacteria known as interspecies electron transfer. It could have important implications for the global carbon cycle and bioenergy.
A broad review of current research on nuclear power economics has been published in the Journal of Renewable and Sustainable Energy. The report concludes that nuclear power will continue to be a viable power source but that the current fuel cycle is not sustainable.
With a new process, chemical engineers can make valuable chemicals such as benzene, toluene and xylenes from pyrolytic oils, the cheapest liquid fuels available today from biomass. This could reduce or eliminate reliance on fossil fuels to make industrial chemicals worth an estimated $400 billion.
