New catalyst paves way for cheap, renewable hydrogen

Scientists have developed a hydrogen-making catalyst that uses cheaper materials and yields fewer contaminants than do current processes, while extracting the element from common renewable plant sources. Further, the new catalyst lies at the heart of a chemical process the authors say is a significant advance in producing alternate fuels from domestic sources.

In the June 27 issue of the journal Science, James Dumesic, John Shabaker and George Huber, of the University of Wisconsin at Madis

Fuel cells agreement: EU and US forge links to provide sustainable energy sources for the future

In the transition to a hydrogen economy, fuel cells could provide the planet with a sustainable energy supply to replace rapidly diminishing fossil fuels. Turning this vision into a reality took a further step forward today with the signing of a EU-US co-operation agreement on fuel cells technology. The agreement brokered by European Research Commissioner Philippe Busquin and the US Secretary or Energy, Mr. Spencer Abraham, aims to strengthen research links, by bringing together EU and US researchers

Breakthrough “Interface Tuning” is Macro Step for Microelectronics

The ability to make atomic-level changes in the functional components of semiconductor switches, demonstrated by a team of Oak Ridge National Laboratory, North Carolina State University and University of Tennessee physicists, could lead to huge changes in the semiconductor industry. The results are reported in the June 13 issue of Science.

Semiconductor devices, the building blocks of computing chips that control everything from coffee makers to Mars landings, depend on microscopic solid-sta

Portable CT Scanner Joins Hunt for Alternative Energy

Lawrence Berkeley National Laboratory (Berkeley Lab) scientists have developed the world’s first x-ray computed tomography (CT) scanner capable of examining entire core samples at remote drilling sites. The portable device, which employs the same high-resolution imaging technology used to diagnose diseases, could help researchers determine how to best extract the vast quantities of natural gas hidden under the world’s oceans and permafrost.

The scanner images the distribution of gas hydrate

Powering Fuel Cells: Oxide Materials that "Exhale and Inhale" May Facilitate Small-scale Hydrogen Production

A unique group of oxide materials that readily gives up and accepts oxygen atoms with changes in temperature could be the basis for a small-scale hydrogen production system able to power fuel cells in homes — and potentially in automotive applications.

Scientists have long known that oxides of the rare earth elements cerium (Ce), terbium (Tb), and praseodymium (Pr) can produce hydrogen from water vapor and methane in continuous “inhale and exhale” cycles. By doping iron atoms into the oxid

Making Wind Power More Efficient

A University of Ulster researcher has come up with a new method, using Artificial Intelligence techniques, to forecast wind energy more accurately than ever before.
Predicting how fast the wind will blow has always been a major problem for wind farm operators. It is essential that they have some idea of how much electricity they will be able to produce each day based on the strength of the wind.

Energy forecasting has become a critical factor in the efficient generation of power from w
