For more than five years, Amy Landis, an engineering professor at Arizona State Univ., has led research that is revealing the potential rewards of developing large-scale biofuels production, as well as the potential drawbacks we would face in the effort. According to Landis, lands damaged by industrial waste or other pollutants could be restored sufficiently to support agriculture for growing bioenergy crops.
Researchers at the U.S. Dept. of Energy (DOE)’s Argonne National Laboratory announced a new tool for analyzing the economic impacts of building new compressed natural gas fueling stations. Called JOBS NG, the tool is freely available to the public. Mostly made up of methane, compressed natural gas is an alternative fuel for cars and trucks that can offer greenhouse gas benefits over gasoline.
A new report prepared by analysts from Lawrence Berkeley National Laboratory examines the potential impacts of customer-sited solar photovoltaics on electric utility profitability and rates. The report shows that these impacts can vary greatly depending upon the specific circumstances of the utility and may be reduced through a variety of regulatory and ratemaking measures.
Scientists have scoured cow rumens and termite guts for microbes that can efficiently break down plant cell walls for the production of next-generation biofuels, but some of the best microbial candidates actually may reside in the human lower intestine, researchers report. Their studyis the first to use biochemical approaches to confirm the hypothesis that microbes in the human gut can digest fiber.
As more gardeners and farmers add ground charcoal, or biochar, to soil to both boost crop yields and counter global climate change, a new study by researchers at Rice Univ. and Colorado College could help settle the debate about one of biochar’s biggest benefits: the seemingly contradictory ability to make clay soils drain faster and sandy soils drain slower.
Finding an economical way to store renewable energy from wind or the sun has proved challenging. An alliance of four companies say they have found an answer and are proposing an $8 billion power project that would start with turbines on a huge wind farm in Wyoming and end with enough electricity for over 1 million households in Southern California. The key link is an underground energy storage site carved out of a massive salt formation.
Cleaning up oil sands tailings has just gotten a lot greener thanks to a novel technique developed by Univ. of Alberta civil engineering professors that uses solar energy to accelerate tailings pond reclamation efforts by industry. Instead of using ultraviolet lamps as a light source to treat the water affected by oil sands processes, sunlight alone treats just as efficiently but at a much lower cost.
Donald Sadoway and his colleagues at the Massachusetts Institute of Technology have already started a company to produce electrical-grid-scale liquid batteries, whose layers of molten material automatically separate due to their differing densities. But a newly developed formula substitutes different metals for the molten layers. The new formula allows the battery to work at a much lower temperature.
Over a three-year period, Univ. of North Texas researchers developed and tested structured insulated panel building materials made from kenaf, a plant in the hibiscus family that is similar to bamboo. Kenaf fibers are an attractive prospect because they offer the same strength to weight ratio as glass fibers. The researchers found that the kenaf materials, including composite panels, provide up to 20% energy savings.
Achieving complete breakdown of plant biomass for energy conversion in industrialized bioreactors remains a complex challenge, but new research shows that termite fungus farmers solved this problem more than 30 million years ago. The new insight reveals that the great success of termite farmers as plant decomposers is due to division of labor.
Inertial confinement fusion creates nanosecond bursts of neutrons, ideal for creating data to plug into supercomputer codes that test the U.S. nuclear stockpile. Down the road, it could be useful as a source of energy. Researchers at Sandia National Laboratories’ Z machine have produced a significant output of fusion neutrons, using a method fully functioning for only little more than a year.
A collaboration between scientists in the Univ. of Chicago’s chemistry department, the Institute for Molecular Engineering and Argonne National Laboratory has produced the highest-ever recorded efficiency for solar cells made of two types of polymers and fulllerene. Researchers identified a new polymer that improved the efficiency of solar cells and also determined the method by which the polymer improved the cells’ efficiency.
Researchers at Argonne National Laboratory have created a small scale “hydrogen generator” that uses light and a 2-D graphene platform to boost production of the hard-to-make element. The research also unveiled a previously unknown property of graphene. The 2-D chain of carbon atoms not only gives and receives electrons, but can also transfer them into another substance.
Univ. of Utah physicists read the subatomic “spins” in the centers or nuclei of hydrogen isotopes, and used the data to control current that powered light in a cheap, plastic LED—at room temperature and without strong magnetic fields. The study brings physics a step closer to practical machines that work “spintronically” as well as electronically.
A chinstrap that can harvest energy from jaw movements has been created by a group of researchers in Canada. It’s hoped that the device will be able to generate electricity from eating, chewing and talking, and power a number of small-scale implantable or wearable electronic devices, such as hearing aids, cochlear implants, electronic hearing protectors and communication devices.
For decades, the power conversion efficiency of organic solar cells was hampered by the drawbacks of commonly used metal electrodes, including their instability and susceptibility to oxidation. Now for the first time, researchers at the Univ. of Massachusetts Amherst have developed a more efficient, easily processable and lightweight solar cell that can use virtually any metal for the electrode, effectively breaking the “electrode barrier.”
Yale Univ. associate professor of electrical engineering Minjoo Larry Lee has been awarded $2,540,000 to develop dual-junction solar cells that can operate efficiently at extreme temperatures above 750 F. In addition to converting a portion of the sunlight directly into electricity, the solar cells will use the remainder of the light to heat high-temperature fluids that can drive a steam turbine or be stored for later use.
Sandia National Laboratories’ Institutional Transformation (IX) model helps the federal laboratory reduce its energy consumption and could help other large institutions do the same. The IX model allows planners to experiment with energy conservation measures before making expensive changes. It also models operations-oriented conservation methods.
When Orlando Rios first started analyzing samples of carbon fibers made from a woody plant polymer known as lignin, he noticed something unusual. The material’s microstructure—a mixture of perfectly spherical nanoscale crystallites distributed within a fibrous matrix—looked almost too good to be true.
The price of solar energy in the U.S. continues to fall substantially, according to the latest editions of two annual reports produced by Lawrence Berkeley National Laboratory (Berkeley Lab). A third Berkeley Lab report, written in collaboration with researchers at Yale Univ., the Univ. of Texas at Austin and the DOE, shows that local permitting and other regulatory procedures can significantly impact residential photovoltaic prices.
Imagine being able to switch out the batteries in electric cars just like you switch out batteries in a photo camera or flashlight. Engineers in California are trying to accomplish just that, in partnership with a local San Diego engineering company. Rather than swapping out the whole battery, which is cumbersome and requires large, heavy equipment, engineers plan to swap out and recharge smaller units within the battery, known as modules.
Manufactures of turbine engines for airplanes, automobiles and electric generation plants could expedite the development of more durable, energy-efficient turbine blades thanks to a partnership between Argonne National Laboratory, the German Aerospace Center and the universities of Central Florida and Cleveland State. The ability to operate turbine blades at higher temperatures improves efficiency and reduces energy costs.
Betavoltaics, a battery technology that generates power from radiation, has been studied as an energy source since the 1950s. Now, for the first time using a water-based solution, researchers at the Univ. of Missouri have created a long-lasting and more efficient nuclear battery that could be used for many applications such as a reliable energy source in automobiles and also in complicated applications such as space flight.
