The Race for Alt Fuel
Billions of dollars lost each year as waste heat from industrial processes can be converted into electricity with a technology being developed at the Department of Energy's Oak Ridge National Laboratory.
The high-efficiency thermal waste heat energy converter actively cools electronic devices, photovoltaic cells, computers and large waste heat-producing systems while generating electricity, according to Scott Hunter, who leads the development team. The potential for energy savings is enormous.
"In the United States, more than 50 percent of the energy generated annually from all sources is lost as waste heat," Hunter said, "so this actually presents us with a great opportunity to save industry money through increased process efficiencies and reduced fuel costs while reducing greenhouse gas emissions."

Thirty-six years after federal overseers of safety at nuclear plants first recognized the serious risks of fires—when a candle ignited a major emergency at the Browns Ferry nuclear plant—preventable fire hazards still persist at the nation’s reactors, including Browns Ferry.
On Tuesday, the Nuclear Regulatory Commission was back at the site of the nation’s worst reactor fire, in 1975, this time to issue a rare “red” safety violation—considered a matter of “high safety significance.” A valve critical for reactor cooling in the event of a fire or other accident had failed. The valve may have been inoperable for more than two years. Read more ..
Edge on China
|Christina Lin||May 18th 2011|
China’s widesspread energy investments have extended to most every corner of the Greater Middle East, particularly the Caspian Basin and key nodes such as Iran, Turkey, and Greece. In many cases, this growing economic foothold has translated into a military foothold as well, given the large-scale participation of Chinese army personnel in energy projects and the “strategic partnerships” that Beijing has formed with key states.
In the Caspian Sea Basin, China has invested most heavily in Kazakhstan, Turkmenistan, and Iran, in addition to increasing its ties with Azerbaijan. Read more ..
The Race for Nuclear
The Department of Energy is responsible for managing almost 13,000 metric tons of nuclear waste at sites in Colorado, Idaho, New York, South Carolina, and Washington. For the past three decades, DOE planned to permanently dispose nuclear waste at Yucca Mountain, a geological repository in southwest Nevada. The cancellation of the project by the Obama administration in 2009 has left the department scrambling to come up with alternatives.
Since 1983, DOE has spent $14 billion to research potential sites, develop technical documents and apply to the Nuclear Regulatory Commission for a license for the Yucca Mountain repository, which was slated to open in 2020. When the administration decided to terminate the Yucca Mountain program and proposed cutting its funding, DOE tried to withdraw its license application from NRC. The commission declined to do so. As a result, the status of the Yucca Mountain program is still in limbo, but the DOE and Navy do not have backup plans in place for a different location the nuclear waster could be stored.

The Race for Solar Energy
A bold new design for thin film solar cells that requires significantly less silicon – and may boost their efficiency – is the result of an industry/academia collaboration between Oerlikon Solar in Switzerland and the Institute of Physics' photovoltaic group at the Academy of Sciences of the Czech Republic.
One long-term option for low-cost, high-yield industrial production of solar panels from abundant raw materials can be found in amorphous silicon solar cells and microcrystalline silicon tandem cells (a.k.a. Micromorph)—providing an energy payback within a year.
A drawback to these cells, however, is that the stable panel efficiency is less than the efficiency of presently dominate crystalline wafer-based silicon, explains Milan Vanecek, who heads the photovoltaic group at the Institute of Physics in Prague. Read more ..

Since China became an energy importer in 1993, it has adopted a “go out” strategy to procure energy assets abroad. Enabled by the Shanghai Cooperation Organization (SCO), Beijing is reviving the strong economic connection between China and the Middle East; for centuries, the trade carried along the Silk Road was important to the economies of both areas. Along much the same route as the Silk Road, and along the sea trade routes between China and the Middle East, Beijing is building a modern grid of pipelines, roads, and railways for its enegy supplies, in addition to addressing maritime concerns.
Snapshot of Current Energy Consumption
In August 2010, a report from the Paris-based International Energy Agency stated that China had become the world’s number-one energy consumer, surpassing the United States. Specifically, China consumed 2.252 billion tons of oil equivalent in 2009—about 4 percent more than the United States, which consumed 2.170 billion tons of oil equivalent. (The oil equivalent metric represents all forms of energy consumed: crude oil, nuclear power, coal, natural gas, renewable sources, etc.) Read more ..
The Race for EVs

Better Place will begin selling electric cars in Israel this summer according to an April 26 report in Israeli newspaper, Yediot Ahronot. The electric car infrastructure company founded by Shai Agassi, has reportedly closed its visitor's center near Tel Aviv and will convert it into a sales center. The first electric car to be sold to Israeli customers by Better Place is the Renault Fluence ZE. It will be followed by the Renault Zoe.
Israel is the first country in the world to install the cutting edge electric car network and will act as a pilot for a worldwide electric car grid. The Dor Alon gas station chain earlier signed an agreement to install battery replacement points for the electric vehicles at all of its gas stations. A sales center at Glilot Junction will be the company's flagship store, and will be built in a huge warehouse that was used previously to store fuel. Read more ..
Race for Solar
High-performance nanotech materials arrayed on a flat panel platform demonstrated seven to eight times higher efficiency than previous solar thermoelectric generators, opening up solar-thermal electric power conversion to a broad range of residential and industrial uses, a team of researchers from Boston College and MIT report in the journal Nature Materials.
Two technologies have dominated efforts to harness the power of the sun's energy. Photovoltaics convert sunlight into electric current, while solar-thermal power generation uses sunlight to heat water and produce thermal energy. Photovoltaic cells have been deployed widely as flat panels, while solar-thermal power generation employs sunlight-absorbing surfaces feasible in residential and large-scale industrial settings.

The Race for Pressure Energy
Electrical engineers at the University of Michigan have built a device that can harness energy from vibrations and convert it to electricity with five to 10 times greater efficiency and power than other devices in its class. And it's smaller than a penny.
"In a tiny amount of space, we've been able to make a device that generates more power for a given input than anything else out there on the market," said Khalil Najafi, one of the system's developers and chair of Electrical and Computer Engineering at the Ann Arbor-based institution.
This new vibration energy harvester is specifically designed to turn the cyclic motions of factory machines into energy to power wireless sensor networks. These sensor networks monitor machines' performance and let operators know about any malfunctions. Read more ..
The Race for Biomass
|Ronnie Greene||May 2nd 2011|
Just 12 miles apart in the belly of California, a pair of 12.5 megawatt power plants fouled the air with a toxic brew of pollutants — nitrogen dioxide, sulfur dioxide, carbon monoxide, ammonia, and particulate matter. They released thick plumes and visible dust. They failed to install proper monitoring equipment, and failed to file reports on their emissions.
Another instance of coal plants polluting the environment?
Not quite. These are biomass power plants, part of the so-called green wave of the future.
Pitched as a smarter, environmentally-friendly way to produce power, the electricity generating stations are spreading nationwide, spurred by hundreds of millions in stimulus dollars and big muscle support from members of Congress and the U.S. Environmental Protection Agency. Generating electricity by burning trees, construction debris, poultry litter, and agricultural mass has become a key element in a larger push to develop sources of alternative energy, and popular because it’s been around for decades and is reliable.

Over the past decade, China has increased its energy foothold in the Greater Middle East, encompassing the mainly Islamic countries of Central Asia, the Caucasus, Southwest Asia, and parts of the Balkans and North Africa. Much of this activity has been rooted in China’s tendency to view energy security in geopolitical and strategic terms rather than purely economic terms. In particular, Beijing has been concerned about countering Western energy initiatives in the region. As one Chinese scholar argued, projects such as the Baku-Tbilisi-Ceyhan (BTC) oil pipeline—the first regional pipeline directly supported and controlled by Western countries—imply American motives of containing Russia and China.

Last fall, Iris Cross beamed into millions of homes, the friendly BP worker hailing from New Orleans who assured TV viewers that the oil giant wouldn’t stop cleaning up the worst oil spill in U.S. history “until we make this right.”
She became the very public face of BP, a soothing contrast to former CEO Tony Heyward, whose PR gaffes cemented public opinion against the oil company.
This is not the first time Cross sought to soothe public anger from a BP disaster. One of her efforts in 2006 so angered a judge that BP was accused of jury tampering and threatened with fines and contempt charges. Read more ..

Los Alamos National Laboratory scientists have developed a way to avoid the use of expensive platinum in hydrogen fuel cells, the environmentally friendly devices that might replace current power sources in everything from personal data devices to automobiles.
In a paper prepared by Los Alamos researchers Gang Wu, Christina Johnston, and Piotr Zelenay, joined by researcher Karren More of Oak Ridge National Laboratory, describe the use of a platinum-free catalyst in the cathode of a hydrogen fuel cell. Eliminating platinum—a precious metal more expensive than gold—would solve a significant economic challenge that has thwarted widespread use of large-scale hydrogen fuel cell systems. Read more ..

With gas prices rising, the rhetoric in Washington about drilling is becoming increasingly intense.
On one side of the battle, is President Obama. He recently outlined a proposal to reduce the country’s dependence on foreign oil by one-third by 2025, while continuing to drill responsibly, beefing up fuel-economy standards and promoting electric vehicles.
On the other side of the battle are Republicans and many drill-state Democrats. While they agree with Obama’s policy agenda broadly, they say the administration is not moving quickly enough to expand domestic oil and natural gas production. Read more ..

Sunoco asserts that there is no “off-site impact” from clouds of toxic acid—to a skeptical audience.
The general manager of the Sunoco oil refinery in Philadelphia defended his company’s decision to keep using an extremely toxic, cloud-forming acid, saying on April 21 that in 40 years “there has not been a single, documented incident of off-site impact or injury to a member of the public.”
Testifying at a legislative hearing on risks posed to workers and neighborhoods by hydrofluoric acid, or HF, the manager, Mike Bukowski, did not find a sympathetic audience, even after explaining that Sunoco had spent $125 million to switch to a modified form of the acid, less likely than standard HF to travel long distances if discharged during an accident.

Race for Bio-Fuel
|Scott Loarie||April 25th 2011|
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.

“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 ..

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 ..

“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.

The Keystone XL project, proposed by TransCanada, would transport Canadian oil sands from Alberta, Canada to refineries on the Texas Gulf coast. Read more ..
The Race for Solar
|Paul Buckley||April 11th 2011|
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 ..

Ecuador’s decision to forego potentially lucrative oil drilling in the Amazon forest in order to protect a biologically rich and fragile ecosystem is the focus of two documentaries at the Washington Environmental Film Festival.
The decision represents a huge sacrifice for a small South American country which earns half its export revenues from oil.
In 2007, Ecuadorian President Rafael Correa boldly halted operations at one of the country’s most promising wells. That amounts to 25 percent of Ecuador’s known oil reserves, which works out to about 846 million barrels of crude. The oil sits below Yasuni National Park, one of the most biologically diverse places on the planet. Read more ..

In a $250 million deal, Israel's Evida will supply the batteries, cooling systems and software tools to run Mia Electric's vehicles in Europe. Batteries for Mia Electric's vehicles will be supplied by Israeli company Evida. Racing from one business meeting to the next, Asher Bennett, the 42-year-old founder of Israeli electric battery maker Evida, couldn't elaborate on how he came up with the invention in such a short time. But the former military submarine man did say that his company has been in stealth mode for the last two years.
Under the media's radar until now, Evida has just signed a $250 million contract with the French-German automaker Mia Electric to manufacture its batteries. Funded with about $2 million from the Israeli venture capital firm Terra Venture Partners, and backed by private investment, Evida has been contracted to provide 50,000 8-kilowatt/hour battery packs for three of Mia's newest electric models, through to the year 2016.

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. Now, Kieffer and his collaborators have produced fluorescent OLEDs with close to 10 percent efficiency. 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.
“Measuring the impact of Recovery Act funding has been a challenge for DOE. It has had particular difficulty providing an accurate assessment of the act’s impact on jobs, environmental risk reduction, and the life-cycle costs of its cleanup program,” the General Accounting Office report said.

The researchers' findings will be published in the March 20 advance online edition of the journal Nature Nanotechnology.
Aside from quick-charge consumer electronics, batteries that can store a lot of energy, release it fast and recharge quickly are desirable for electric vehicles, medical devices, lasers and military applications.
"This system that we have gives you capacitor-like power with battery-like energy," said Braun, a professor of materials science and engineering. "Most capacitors store very little energy.

Race for Batteries
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 ..
