Sugarcane Cools the Climate and Reduces Carbon Dioxide Emissions

April 25th 2011

Energy / Environment - Sugar Cane

Brazilians are world leaders in using biofuels for gasoline. About a quarter of their automobile fuel consumption comes from sugarcane, which significantly reduces carbon dioxide emissions that otherwise would be emitted from using gasoline. Now scientists from the Carnegie Institution's Department of Global Ecology have found that sugarcane has a double benefit. Expansion of the crop in areas previously occupied by other Brazilian crops cools the local climate. It does so by reflecting sunlight back into space and by lowering the temperature of the surrounding air as the plants "exhale" cooler water. The research team, led by Carnegie's Scott Loarie, is the first to quantify the direct effects on the climate from sugarcane expansion in areas of existing crop and pastureland of the cerrado, in central Brazil.

Newt Gingrich

“I am not a lobbyist for ethanol,” Newt Gingrich declared in a mid-winter spat with the editors of The Wall Street Journal over his support for government subsidies for alternative fuel.

But Gingrich was a hired consultant to a major ethanol lobbying group—at more than $300,000 a year.

According to IRS records, the ethanol group Growth Energy paid Gingrich’s consulting firm $312,500 in 2009.The former House Speaker was the organization’s top-paid consultant, according to the records. His pay was one of the group’s largest single expenditures, as it took in and spent about $11 million to promote ethanol and to lobby for federal incentives for its use.

In a Growth Energy publication, Gingrich was listed as a consultant who offered advice on “strategy and communication issues” and who “will speak positively on ethanol related topics to media.” Read more ..

Hidden Magnetic Effect could Yield Optical Battery Design

April 20th 2011

Energy Topics - Light magnet

A dramatic and surprising magnetic effect of light discovered by University of Michigan researchers could lead to solar power without traditional semiconductor-based solar cells. The researchers found a way to make an "optical battery," according to Stephen Rand, a professor in the departments of Electrical Engineering and Computer Science, Physics and Applied Physics. In the process, they overturned a century-old tenet of physics. "You could stare at the equations of motion all day and you will not see this possibility. We've all been taught that this doesn't happen," said Rand. "It's a very odd interaction. That's why it's been overlooked for more than 100 years."

Light has electric and magnetic components. Until now, scientists thought the effects of the magnetic field were so weak that they could be ignored. What Rand and his colleagues found is that at the right intensity, when light is traveling through a material that does not conduct electricity, the light field can generate magnetic effects that are 100 million times stronger than previously expected. Under these circumstances, the magnetic effects develop strength equivalent to a strong electric effect. Read more ..

Japan’s Nuclear Crisis Stimulating Solar Markets in Europe

April 18th 2011

Energy Topics - Solar panels

“Reaction to the Fukushima nuclear crisis has been swift in Germany and Italy,” commented Henning Wicht, senior director and principal analyst for photovoltaic systems at IHS iSuppli. “Germany responded quickly by shutting down seven of its oldest reactors, potentially boosting the prospects for renewable energy in the country. Meanwhile, Italy indicated it might upgrade the role of solar within the country and accept higher volumes of sun-powered energy.”

IHS noted that, by the third quarter of 2011, it will be clearer whether the German government is likely to proceed with a rapid exit from nuclear power. In that case, renewable energy is expected to be promoted more strongly. Wind dominates current public discussions, but solar energy possibly could benefit as well. One possible course of action that could benefit the solar industry would boost the annual photovoltaic (PV) installation forecast. Read more ..

Cornell University professors will soon publish research that concludes natural gas produced with a drilling method called “hydraulic fracturing” contributes to global warming as much as coal, or even more. The conclusion is explosive because natural gas enjoys broad political support – including White House backing – due to its domestic abundance and lower carbon dioxide emissions when burned than other fossil fuels. Cornell Prof. Robert Howarth, however, argues that development of gas from shale rock formations produced through hydraulic fracturing – dubbed “fracking” – brings far more methane emissions than conventional gas production.

Scientists develop Golden Window Electrodes for Organic Solar Cells

April 11th 2011

Science - Warwick golden electrode

Researchers at the University of Warwick have developed a gold plated window as the transparent electrode for organic solar cells. The electrodes have the potential to be relatively cheap since the thickness of gold used is only 8 billionths of a meter. The ultra-low thickness means that even at the current high gold price the cost of the gold needed to fabricate one square metre of this electrode is only around $10.

Organic solar cells have long relied on Indium Tin Oxide (ITO) coated glass as the transparent electrode, although this is largely due to the absence of a suitable alternative. ITO is a complex, unstable material with a high surface roughness and tendency to crack upon bending if supported on a plastic substrate. The short supply of indium is making it relatively expensive to use. Read more ..

University of Michigan engineering researchers have designed an exceptionally efficient fluorescent blue OLED, or organic light emitting diode.

OLEDs are the next generation display technology. They are already used in televisions, cell phones and computers, and they are candidates for a vast array of light sources from advertising billboards to indoor and outdoor illumination. Fluorescent OLEDs are typically less efficient at emitting light per unit area than their phosphorescent counterparts.

That may be changing, according to new findings by professor John Kieffer and graduate student Changgua Zhen of the Department of Materials Science and Engineering. They released findings in the journal Advanced Functional Materials that shattered previous records. Traditionally, the ceiling for the efficiency of fluorescent OLEDs was believed to be 5 percent.

India's Garbage Points to New Power Source

Some of India's most remote farming villages are beginning to see sundown in a new light, now that they are able to convert an abundant crop into electricity.

Remote regions are prime examples of what people describe as old India - parts of the country off the grid, literally, from new India and its high-tech urban centers.

Tamkuha, in the Indian state of Bihar, does not receive electricity from the country's main distribution network. It gets by on traditional farming - and for decades, as the sun went down, villagers turned to the dim light of candles or kerosene lamps.

But these days, thanks to an ambitious renewable energy project, life in Tamkuha no longer grinds to a halt around 6:00 p.m.  By the glow of florescent bulbs, residents have been able to extend their hours of productivity late into the night. A woman says she used to work as a tailor only during the day. Sewing was nearly impossible with a kerosene lamp. Now, she says she can work in her shop until very late at night. Read more ..

The Department of Energy has struggled to show how its $41.7 billion in stimulus funding created jobs, reduced environmental risks or improved nuclear waste cleanup.

Program funds went to energy efficiency, home weatherization, nuclear waste cleanup, and a loan guarantee program to promote renewable energy technology.

The loan guarantee program for renewable energy provided $6 billion in credits to eligible companies, but due to concerns with the administration of the program, Congress has reduced those funds by almost $4 billion. DOE only obligated 17 percent of the remaining $2.5 billion in the fund and will lose about $2 billion if it does not make final decisions on loan guarantees soon.  Borrowers must begin construction on their projects by Sept. 30.

Making Batteries Affordable is Key to Harnessing Wind and Solar Power

March 14th 2011

Energy Topics - Wind turbines in cloudy sky

Future batteries used by the energy grid to store power from the wind and sun must be reliable, durable and safe, but affordability is really the key to widespread deployment, according to a new report. The report is one of the most comprehensive reviews of electrochemical energy storage to date.

In the report, researchers from the Department of Energy's Pacific Northwest National Laboratory say that successful electrochemical energy storage, or EES, systems will need to evolve — in some cases, considerably — if they are going to compete financially with the cost of natural gas production.  And besides technical improvements, the systems will need to be built to last, using materials that are safe and durable so that batteries could operate more than 15 years and require very little maintenance over their lifetime.

The report provides a comprehensive review of four stationary storage systems — ones considered the most promising candidates for EES: vanadium redox flow, sodium-beta alumina membrane, lithium-ion and lead-carbon batteries. In their study, the PNNL researchers note the potential of each technology but, more importantly, explain what advances must occur with each if they're ultimately to be deployed. Read more ..

Sandia National Laboratories researchers in New Mexico are moving into the demonstration phase of a novel gas turbine system for power generation, with the promise that thermal-to-electric conversion efficiency will be increased to as much as 50 percent—an improvement of 50 percent for nuclear power stations equipped with steam turbines, or a 40 percent improvement for simple gas turbines. The system is also very compact, meaning that capital costs would be relatively low.

Research focuses on supercritical carbon dioxide (S-CO2) Brayton-cycle turbines, which typically would be used for bulk thermal and nuclear generation of electricity, including next-generation power reactors. The goal is eventually to replace steam-driven Rankine cycle turbines, which have lower efficiency, are corrosive at high temperature and occupy 30 times as much space because of the need for very large turbines and condensers to dispose of excess steam. The Brayton cycle could yield 20 megawatts of electricity from a package with a volume as small as four cubic meters. Read more ..

Over-Fertilization is Bad for the Environment and Bad for Biofuel

February 28th 2011

Energy / Environment - Biofuel field

A study conducted by Rice University researchers shows how farmers can save money on fertilizer while they improve their production of feedstock for ethanol and alleviate damage to the environment.

The research has implications for an industry that has grown dramatically in recent years to satisfy America's need for energy while trying to cut the nation's reliance on fossil fuels.

The Houston TX team led by postdoctoral researcher Morgan Gallagher as part of her dissertation at Rice discovered that corn grain, one source of ethanol, and the stalks and leaves, the source of cellulosic ethanol, respond differently to nitrogen fertilization.

The researchers found that liberal use of nitrogen fertilizer to maximize grain yields from corn crops results in only marginally more usable cellulose from leaves and stems. And when the grain is used for food and the cellulose is processed for biofuel, pumping up the rate of nitrogen fertilization actually makes it more difficult to extract ethanol from corn leaves and stems.

This happens, they discovered, because surplus nitrogen fertilizer speeds up the biochemical pathway that produces lignin, a molecule that must be removed before cellulosic ethanol can be produced from corn stems and leaves. Read more ..

Unlike energy produced in most African states, nearly all of Libya’s oil and natural gas is produced onshore. This reduces development costs but increases the chances that political instability could impact output — and Libya has been anything but stable of late.

Libya’s 1.8 million barrels per day (bpd) of oil output can be broken into two categories. The first comes from a basin in the country’s western extreme and is exported from a single major hub just west of Tripoli. The second basin is in the country’s eastern region and is exported from a variety of facilities in eastern cities. At the risk of oversimplifying, Libya’s population is split in half: Leader Moammar Gadhafi’s power base is in Tripoli in the extreme west, the opposition is concentrated in Benghazi in the east, with a 600 kilometer-wide gulf of nearly empty desert in between.
