Nanoantenna array could be vast improvement over silicon

February 5, 2013 12:01 pm | by Colin Poitras, University of Connecticut | News | Comments

For years, scientists have studied the potential benefits of a new branch of solar energy technology that relies on incredibly small nanosized antenna arrays that are theoretically capable of harvesting more than 70% of the sun’s electromagnetic radiation and simultaneously converting it into usable electric power. A new fabrication technique developed by University of Connecticut engineering professor Brian Willis could provide the breakthrough for this technology.

Energy industry develops nontoxic fracking fluids

February 3, 2013 12:23 pm | by KEVIN BEGOS - Associated Press - Associated Press | News | Comments

The oil and gas industry is trying to ease environmental concerns by developing nontoxic fluids for the drilling process known as fracking, but it's not clear whether the new product will be widely embraced by drilling companies. Houston-based energy giant Halliburton Inc. has developed a product called CleanStim, which uses only food-industry ingredients. Other companies have developed nontoxic fluids as well.

An enhanced battery technology that can potentially reduce the time it takes to charge cell phones, electric vehicles, and other battery-powered devices from hours to minutes is the subject of a commercial license agreement between Battelle and Vorbeck Materials Corp. The agreement will allow Vorbeck to bring lithium batteries incorporating Vor-X graphene technology to market for use in consumer portable electronic and medical devices, tools, and electric vehicles.


Ethanol industry turns to plant residue, scraps

January 31, 2013 6:13 am | by DAVID PITT - Associated Press - Associated Press | News | Comments

After decades of talk, the ethanol industry is building multimillion dollar refineries in several states that will use corn plant residue, wood scraps and even garbage to produce the fuel additive. The breakthrough comes at a key time for the industry, after the drought heightened criticism about the vast amount of corn used to brew up ethanol rather than be transformed into animal feed or other foods.

Wind in the willows boosts biofuel production

January 21, 2013 9:43 am | News | Comments

A curious characteristic of willows is that when they are cultivated for green energy they can yield five times more biofuel if they grow diagonally, compared with those that grow naturally straight up. Scientists were previously unable to explain why some willows produced more biofuel than others, but researchers have now identified a genetic trait that causes this effect and is activated in some trees when they sense they are at an angle, such as where they are blown sideways in windy conditions.

Doubling down on energy efficiency

January 18, 2013 11:15 am | by Allan Chen, Berkeley Lab | News | Comments

Recent research at Lawrence Berkeley National Laboratory finds utility customer-funded energy efficiency programs expanding across the United States. Spending on these programs, which are funded by mandatory charges on utility bills, will double to nearly $10 billion per year by 2025. Drivers for this growth include energy efficiency resource standards required of utilities.

December 21, 2012 9:21 am | News | Comments

The Federal Laboratory Consortium announced this week that the Department of Energy national laboratory in Richland is receiving three 2013 Excellence in Technology Transfer awards in recognition for creating technologies or processes that can store large amounts of renewable energy until it's needed, fight cancer and detect explosives, and then moving the innovations to the marketplace.

Analysis of Marcellus flowback finds high levels of ancient brines

December 19, 2012 9:03 am | News | Comments

According to a recent study, brine water that flows back from gas wells in the Marcellus Shale region after hydraulic fracturing is many times more salty than seawater, with high contents of various elements, including radium and barium. The findings show that these elements, found in high levels in the late stages of hydraulic fracturing, come from the ancient brines rather than from salts dissolved by the water and chemicals used as part of the fracking process.

Study: Wind, solar, and energy storage could power electric grid

December 11, 2012 9:49 am | by Teresa Messmore, University of Delaware | News | Comments

According to new research by the University of Delaware, renewable energy could fully power a large electric grid 99.9% of the time by 2030 at costs comparable to today’s electricity expenses. The study’s authors developed a computer model to consider 28 billion combinations of renewable energy sources and storage mechanisms, each tested over four years of historical hourly weather data and electricity demands.

Energy experts say drilling can be made cleaner

December 11, 2012 8:46 am | by Kevin Begos and Seth Borenstein, Associated Press | News | Comments

In the Colorado mountains, a spike in air pollution has been linked to a boom in oil and gas drilling. About 800 miles away on the plains of north Texas, there's a drilling boom, too, but some air pollution levels have declined. Opponents of drilling point to Colorado and say it's dangerous. Companies point to Texas and say drilling is safe.

The SolerCool container and business venture has been developed as a solar generator that can store energy.


DOE, NASA demonstrate simple, robust fission reactor

November 27, 2012 11:18 am | News | Comments

A team of researchers have built a new type of nuclear reactor that is reliable enough to be used on space flights. The prototype, which has been used to generate 24 W of electricity, relies on heat pipe technology developed at Los Alamos National Laboratory in 1983. The fluid-based cooling system requires no moving parts and the reactor itself is based on a simply closed-loop Stirling engine.

New study shows saltwater algae viable for biofuels

November 26, 2012 5:32 pm | News | Comments

The Algae Biomass Organization, the trade association for the U.S. algae industry, this week hailed a  new University of California San Diego study showing saltwater algae is just as capable as freshwater algae in producing biofuels. The findings may mean that algae production will no longer be tied to constraints placed on the use of freshwater. They also suggest potential use of up to 10 million acres of land otherwise unsuitable for agriculture.
