Purity Tests for Fuel Cell Technology

Purity Tests for Fuel Cell Technology

Alternate Energy Corporation (AEC) announced results of the company's hydrogen purity testing. The company claims their low-cost hydrogen production system will help enable residential and commercial customers generate their own electricity off-grid at on-grid competitive prices.
Solarfun Introduces Eclipse With Reduced LID

Solarfun Introduces Eclipse With Reduced LID

Solarfun Power Holdings Co. Ltd. announced the introduction of Eclipse, a new line of PV cells and modules with reduced light induced degradation (LID). The largest percentage of degradation of PV modules occurs during the first day of sun exposure.
Computational Models Help Test Hydrogen Separation

Computational Models Help Test Hydrogen Separation

[RenewableEnergyAccess.com] The cost of hydrogen production is said to far outweigh the energy return of the gas, but a complex computer program could help to bring the production price down. The Department of Energy’s National Energy Technology Laboratory (NETL) and Carnegie Mellon University have developed a new computational modeling tool that predicts hydrogen flux through metal alloy separation membranes. These […]
LANXESS Introduces Smart Chemistry for Green Fuel

LANXESS Introduces Smart Chemistry for Green Fuel

Berlin, Germany [RenewableEnergyAccess.com] At the Fuels of the Future trade conference, taking place November 27 – 28 in Berlin, chemical company LANXESS will showcase its biodiesel technology. The Baynox range stabilizes biodiesel and keeps it from oxidizing and, therefore, damaging the engine. The Lewatit K 2567, a type of ion exchange resin, absorbs impurities in biodiesel without generating wastewater, as […]
Will Biodiesel Get a Boost from the New EPA Diesel Mandates?

Will Biodiesel Get a Boost from the New EPA Diesel Mandates?

Will the EPA mandated change to Ultra Low Sulfur Diesel fuel next October provide any stimulus for biodiesel in the U.S.? - Thomas S., Boston, MA
A Step Closer to the Optimum Solar Cell

A Step Closer to the Optimum Solar Cell

Besides cost, the most fundamental issue in assessing photovoltaic solar cells is efficiency - how much of the sunlight that falls on the cell can it convert to electricity? For the second time in two years, Kin Man Yu and Wladek Walukiewicz of the Materials Sciences Division, working with colleagues from Berkeley Lab and other institutions, have announced a new solar cell material that may be able to achieve extraordinary efficiency. In every other way these discoveries are different, however.
Melting Silicon in Reverse

Melting Silicon in Reverse

Like an ice cube on a warm day, most materials melt -- that is, change from a solid to a liquid state -- as they get warmer. But a few oddball materials do the reverse: They melt as they get cooler. Now a team of researchers at MIT has found that silicon, the most widely used material for computer chips and solar cells, can exhibit this strange property of "retrograde melting" when it contains high concentrations of certain metals dissolved in it.
Solar Power Research Looks to Nanotechnology

Solar Power Research Looks to Nanotechnology

While the sun is a clean, inexhaustible source of energy, it's relatively expensive compared to the current tendency towards fossil fuels. As issues of pollution and dependence on finite resources become more pressing, lowering the price of solar-powered generation is a major goal of many scientists and companies in the industry.
PHOTOVOLTAICS: Research targets more-efficient photovoltaics

PHOTOVOLTAICS: Research targets more-efficient photovoltaics

Innovative research, including bandgap engineering and new approaches to organic photovoltaics, aims to create cheaper, more-efficient solar cells suitable for widespread use.
Start-up Says It Can Make Solar Panels out of Dirty Silicon

Start-up Says It Can Make Solar Panels out of Dirty Silicon

[CNET NewsBlog] You can make solar panels with impure silicon, claims Roy Johnson. You just have to know how to isolate the undesirables. CaliSolar, a solar start-up that derives from research originally conducted at UC Berkeley, has come up with a way to make solar cells out of upgraded metallurgical silicon, which is less pure and less costly than the […]
