In the wake of the sobering news that atmospheric carbon dioxide is now at its highest level in at least three million years, an important advance in the race to develop carbon-neutral renewable energy sources has been achieved. Scientists with Lawrence Berkeley National Laboratory have reported the first fully integrated nanosystem for artificial photosynthesis.
The California Energy Commission has awarded $1.7 million to a partnership between Lawrence Livermore National Laboratory and Cool Earth Solar Inc. to conduct a community-scale renewable energy integration demonstration project at the Livermore Valley Open Campus.
U.S. Department of Energy Joint BioEnergy Institute researchers have developed an enzyme-free ionic liquid pretreatment of cellulosic biomass that makes it easier to recover fermentable sugars for biofuels and to recycle the ionic liquid.
The growing global demand for energy, combined with a need to reduce emissions and lessen the effects of climate change, has increased focus on cleaner energy sources. But what unintended consequences could these cleaner sources have on the changing climate? Researchers at Massachusetts Institute of Technology now have some answers to that question, using biofuels as a test case.
Technology created an energy revolution over the past decade—just not the one we expected. By now, cars were supposed to be running on fuel made from plant waste or algae—or powered by hydrogen. Electricity would be generated with solar panels and wind turbines. Fossil fuels? They were going to be expensive and scarce. But in the race to conquer energy technology, Old Energy is winning.
Technology created an energy revolution over the past decade—just not the one we expected. By now, cars were supposed to be running on fuel made from plant waste or algae—or powered by hydrogen or cheap batteries that burned nothing at all. Electricity would be generated with solar panels and wind turbines. When the sun didn't shine or the wind didn't blow, power would flow out of batteries the size of tractor-trailers.
Nanotechnology typically describes any material, device, or technology where feature sizes are smaller than 100 nanometers in dimension. However, this new and uncharted direction in research provides a large spark for new product and drug delivery development. To achieve these discoveries, scientists must rely on specialized instruments and materials to drive their experiments and analysis.
The U.S. Department of Energy and the state of Alaska will collaborate on future research of unconventional energy resources in the Arctic, including abundant reservoirs of methane hydrate. The DOE's acting assistant secretary for fossil energy, Christopher Smith, and Alaska Department of Natural Resources Commissioner Dan Sullivan announced the agreement Tuesday.
A unique atomic-scale engineering technique for turning low-efficiency photocatalytic “white” nanoparticles of titanium dioxide into high-efficiency “black” nanoparticles could be the key to clean energy technologies based on hydrogen. Samuel Mao leads the development of a technique for engineering disorder into the nanocrystalline structure of the semiconductor titanium dioxide.
Tougher EPA air-quality standards could spur an increased shift away from coal and toward natural gas for electricity generation, according to a new Duke University study. Complying with stricter regulations on sulfur dioxide, particulate matter, nitrogen oxide, and mercury may make nearly two-thirds of the nation's coal-fired power plants as expensive to run as plants powered by natural gas. The regulations would make 65% of U.S. coal plants as expensive as natural gas, even if gas prices rise significantly.
A team of Virginia Tech researchers has discovered a way to extract large quantities of hydrogen from any plant, a breakthrough that has the potential to bring a low-cost, environmentally friendly fuel source to the world.
A House panel on Wednesday narrowly approved an effort to scale back and ultimately repeal a 2007 law requiring North Carolina electric utilities to generate a percentage of their power through alternative sources and locate energy savings. The House commerce subcommittee voted 11-10 in favor of the bill that would cap renewable energy and efficiency requirements by power companies, electric cooperatives, and city-owned electric utilities at roughly half the level the law ultimately demands.
A carbon price of between $50 and $100 per ton of carbon dioxide would make coal-fired and gas-fired power less economical than renewable electricity, a University of New South Wales study shows. The study shows that fossil-fueled power stations in Australia’s National Electricity Market could be phased out and replaced economically and reliably with commercially available renewable energy technologies by increasing the carbon price to this “medium” level.
The construction of the photovoltaic power industry since 2000 has required an enormous amount of energy, mostly from fossil fuels. The good news is that the clean electricity from all the installed solar panels has likely just surpassed the energy going into the industry's continued growth, Stanford University researchers find.
Japan's Cabinet has approved a proposal to revamp its troubled electricity industry and foster more competition by obliging utilities to split power generation and distribution into separate businesses. The plan is meant to encourage more innovation and modernization of the power grid as the country grapples with its energy policy following the shut-downs of almost all its nuclear power plants after the March 2011 tsunami disaster at the Fukushima Dai-Ichi plant.
Rice University researchers are developing a comprehensive model that will predict how brine, oil, and gas drawn from ultradeep wells react to everything encountered on the way up to the surface and to suggest strategies to maintain the flow.
Taking their inspiration from Nature, scientists at the University of New South Wales have developed a new method for carrying out chemical reduction—an industrial process used to produce fuels and chemicals that are vital for modern society. Their catalyst-based approach has the big advantages that it uses cheap, replenishable reagents and it works well at room temperature and in air—so much so, it can even be carried out safely in a teacup.
Researchers at the U.S. Naval Research Laboratory have successfully demonstrated pulse tailoring, producing a time varying focal spot size known as “focal zooming” on the Nike laser, the world's largest operating krypton fluoride gas laser. The use of focal zooming in inertial fusion energy system is expected to reduce the required laser size, boosting efficiency and lowering costs
The ultrafast, ultrabright X-ray pulses of the Linac Coherent Light Source (LCLS) have enabled unprecedented views of a catalyst in action, an important step in the effort to develop cleaner and more efficient energy sources. Scientists at the SLAC National Accelerator Laboratory used LCLS, together with computerized simulations, to reveal surprising details of a short-lived early state in a chemical reaction occurring at the surface of a catalyst sample.
Hydraulic fracturing may soon be approved for the state of New York. However, a new study finds that it is technically and economically feasible to convert New York's all-purpose energy infrastructure to one powered by wind, water, and sunlight. The authors say that overall switch would reduce New York's end-use power demand by about 37% and stabilize energy prices.
The salinity difference between freshwater and saltwater could be a source of renewable energy. However, power yields from existing techniques are not high enough to make them viable. A team led by physicists in France has discovered a new means of harnessing this energy. Their method of osmotic flow through boron nitride nanotubes generates electric currents with 1,000 times the efficiency of any previous system.
Royal Dutch Shell PLC announced Wednesday it will not drill for petroleum in the Arctic Ocean in 2013. Shell Oil Co. President Marvin Odum said in an announcement that the company will "pause" its exploration drilling in the Chukchi and Beaufort seas. The company made progress in Alaska, but...
The latest Harvard University research in mesoscale atmospheric modeling suggest that the generating capacity of large-scale wind farms has been overestimated. The research shows that the generating capacity of very large wind power installations (larger than 100 square kilometers) may peak at between 0.5 and 1 Watts per square meter. Previous estimates, which ignored the turbines' slowing effect on the wind, had put that figure at between 2 and 7 Watts per square meter.
According to a new report from the National Research Council, although ignition of fusion fuel has not yet been achieved, the potential benefits of inertial fusion energy justify investment in fusion energy research and development. Scientific and technological progress in inertial confinement fusion over the past decade has been substantial, but continued progress will require a large and concerted effort.
In the search for renewable alternatives to gasoline, heavy alcohols such as isobutanol are promising candidates. Not only do they contain more energy than ethanol, but they are also more compatible with existing gasoline-based infrastructure. For isobutanol to become practical, however, scientists need a way to reliably produce huge quantities of it from renewable sources. Massachusetts Institute of Technology chemical engineers and biologists have now devised a way to dramatically boost isobutanol production in yeast, which naturally make it in small amounts.
