A Better Solar Powered Hydrogen Generator
May 20, 2013 | 1 Comment
National Institute of Standards and Technology (NIST) researchers have new information on what may become a cost-effective way to generate hydrogen gas directly from water and sunlight. The NIST team used a powerful combination of microanalytic techniques that simultaneously image photoelectric current and chemical reaction rates across a surface on a micrometer scale. The target [...]

Extracting Large Quantities of Hydrogen From Plants
April 4, 2013 | 1 Comment
A team of Virginia Tech researchers has discovered a way to extract large quantities of hydrogen from any plant. The team believes their breakthrough that has the potential to bring a low-cost, environmentally friendly hydrogen fuel source to the world. Y.H. Percival Zhang, an associate professor of biological systems engineering in the College of Agriculture [...]

Chemists at the California Institute of Technology (Caltech) and the Lawrence Berkeley National Laboratory believe they can now explain how to build the two-atom oxygen (O2) molecule from splitting water. The O2 forming chemical process is one of the remaining mysteries of photosynthesis that plants use to convert sunlight into usable energy and make the [...]

New Catalyst Efficiently Splits Hydrogen From Water
March 21, 2013 | Leave a Comment
University of Oregon (UO) chemists say that ultra-thin films of nickel and iron oxides are promising catalysts to split to water into hydrogen and oxygen gases. The nickel and iron oxides are made through a solution synthesis process that when combined with semiconductor devices that capture sunlight, can perform electrolysis. The researchers work in the [...]

Solar Efficiently Drives Hydrogen From New H2O Splitter
February 26, 2013 | Leave a Comment
Researchers at the University of California Santa Barbara (UCSB) have developed an efficient, autonomous solar water-splitting device. The new idea is based on a gold nanorod array where essentially all charge carriers involved in the oxidation and reduction steps arise from the hot electrons resulting from the excitation of surface plasmons in the nanostructured gold [...]

Two Big Strides in Hydrogen Production
February 15, 2013 | 2 Comments
First up, biologists at the Ruhr-Universität Bochum (RUB) have uncovered a mechanism for the production of hydrogen that has not been examined in depth before. The team has found how green algae accomplish the unusual process of producing hydrogen in the dark. Professor Dr. Thomas Happe, head of the working group Photobiotechnology explains, “Hydrogen could [...]
