Researchers use simple scaling theory to better predict shale production

November 19, 2013 7:05 am | News | Comments

Scientists at The Univ. of Texas at Austin have developed a new method to estimate gas production from hydraulically fractured wells in the Barnett Shale. The approach, which uses a simple physics theory called scaling, is intended to help the energy industry accurately identify low- and high-producing horizontal wells, as well as accurately predict how long it will take for gas reserves to deplete in the wells.

Next generation of biofuels is still years away

November 14, 2013 12:54 pm | by Jonathan Fahey, Associated Press | News | Comments

The first trickle of fuels made from agricultural waste is finally winding its way into the nation's energy supply. But the full benefits of this fuel source remain many years away, and ethanol, which was meant to be a stop-gap until non-food sources of fuel were found, has been far more damaging to the environment than the government predicted.

The Swiss Federal Institute of Technology in Lausanne’s new convention center, opening in April 2014, is being equipped with a glass façade composed of dye solar cells. The project, a world’s first for an exterior window, leverages the potential of dye-sensitive solar cells known as Graetzel cells, which are indifferent to the angle of incidence of light that hits them.

Calif. finds more instances of offshore fracking

October 21, 2013 7:56 am | by Alicia Chang and Jason Dearen, Associated Press | News | Comments

In waters off Long Beach, Seal Beach and Huntington Beach—some of the region's most popular surfing strands and tourist attractions—oil companies have used fracking at least 203 times at six sites in the past two decades. This discovery made from drilling records and interviews shows that offshore fracking is more widespread and frequent that state officials believed.

Why lithium-ion-batteries fail

October 18, 2013 9:48 am | by Peter Rüegg, ETH Zurich | News | Comments

Materials in lithium ion battery electrodes expand and contract during charge and discharge. These volume changes drive particle fracture, which shortens battery lifetime. A group of scientists has quantified this effect for the first time using high-resolution 3D movies recorded using x-ray tomography at the Swiss Light Source.

Researchers address economic dangers of “peak oil”

October 16, 2013 3:08 pm | News | Comments

Experts from the Univ. of Maryland and a leading university in Spain demonstrate in a new study which sectors could put the entire U.S. economy at risk when global oil production peaks. This multi-disciplinary team recommends immediate action by government, private and commercial sectors to reduce the vulnerability of these sectors.

NREL calculates emissions, costs of power plant cycling for wind, solar expansion

September 25, 2013 9:20 am | News | Comments

New research from the National Renewable Energy Laboratory has quantified the potential impacts of increasing wind and solar power generation on operators of fossil-fueled power plants in the West. To accommodate higher amounts of wind and solar power on the electric grid, utilities must ramp down and ramp up or stop and start conventional generators more frequently to provide reliable power for their customers—a practice called cycling.

NSF report details increase in business research and development

September 20, 2013 12:25 pm | News | Comments

According to a recent study published by the National Science Foundation (NSF), businesses spent more on research and development (R&D) in 2011 than they did in 2010. The figures revealed that during 2011, companies in manufacturing industries performed $201 billion, or 68%, of domestic R&D.

Research determines best arrangement of tidal sails device

September 17, 2013 1:09 pm | News | Comments

Just as wind turbines tap into the energy of flowing air to generate electricity, hydrokinetic devices produce power from moving masses of water. Engineers in Spain have performed a computer simulation to determine the optimal configuration of a system produced by a Norwegian company to enable it to extract the maximum amount of energy from any given current.

Study: Methane leaks from gas drilling not huge

September 17, 2013 1:02 pm | by Kevin Begos and Seth Borenstein, Associated Press | News | Comments

According to research published this week drilling and fracking for natural gas don't seem to spew immense amounts of the greenhouse gas methane into the air, as has been feared. The study, mostly funded by energy interests,  doesn't address other fracking concerns about potential air and water pollution, but does generally with government estimates.

Terahertz time-domain spectroscopy for oil and gas detection

September 12, 2013 9:49 am | News | Comments

Kerogen is a mixture of organic chemical compounds in sedimentary rocks that is a key intermediate of oil and natural gas. After five years of research, researchers in China have developed a terahertz time-domain spectroscopy method that effectively detects the generation of oil and gas from kerogen without contact or destruction of the sample material.

Hydroelectric power makes big comeback at U.S. dams

September 12, 2013 9:20 am | by David Pitt, Associated Press | News | Comments

In the 1980s and 1990s, hydroelectric development stagnated as environmental groups lobbied against it and a long regulatory process required years of environmental study. But for the first time in decades, power companies are proposing new projects to take advantage of government financial incentives, policies that promote renewable energy over fossil fuels and efforts to streamline the permit process.

Sharing the risks and costs of biomass crops

September 4, 2013 4:09 pm | News | Comments

Farmers who grow corn and soybeans can take advantage of government price support programs and crop insurance, but similar programs are not available for those who grow biomass crops. A new study recommends a framework for contracts between growers and biorefineries to help spell out expectations and designate who will assume the risks and costs.

Bringing color to solar façades

July 2, 2013 12:21 pm | News | Comments

Designers of buildings typically have no choice but to use black or bluish-gray colored solar panels. With the help of thin-film technologies, however, researchers in Germany have now added color to solar cells. Optics specialists have changed physical thickness of the transparent conductive oxide layer, modifying its refractive index.

Policy issues plague hydropower as wind power backup

June 27, 2013 2:11 pm | by A'ndrea Elyse Messer, Penn State University | News | Comments

Theoretically, hydropower can step in when wind turbines go still, but barriers to this non-polluting resource serving as a backup are largely policy- and regulation-based, according to recent research. Hydroelectric dams are controlled by guide curves that account for drinking water and droughts. They cannot simply release water to meet some electricity demand or hold back water when electricity is in low demand.
