Hydrogen Fuel Cells with an Inexpensive Catalyst

Written by , on January 17, 2013

The problem with hydrogen fuel cells has been the cost of the platinum required as a catalyst. Now, scientists at the University of Cambridge have found that cobalt can function as an efficient catalyst at room temperature in pH neutral water surrounded by oxygen. Cobalt is relatively abundant and, therefore, inexpensive. Lead author of the […]  Read more »

Promising Hydrogen Storage Material

Written by , on December 8, 2012

Engineers at the University of New South Wales have developed a light weight, nano-engineered material that can store and release hydrogen, overcoming a major hurdle to its use as an alternative fuel source. The engineers have synthesised nanoparticles of sodium borohydride and encased these inside nickel shells. The unique "core-shell" nanostructure has remarkable hydrogen storage […]  Read more »

Hydrogen from Water Using Only Sunlight

Written by , on June 14, 2012

Researchers, led by Professor Juan Bisquert, from the Universitat Jaume I in Spain, have developed a device which uses semiconductor materials to generate hydrogen from water using only sunlight. Hydrogen is an extremely abundant element on Earth’s surface – but in combination with oxygen as water (H20). The hydrogen molecule (H2) contains a great amount of energy […]  Read more »

Hydrogen from Sunlight and Water

Written by , on April 12, 2012

Erik Koepf, a doctoral candidate at the University of Delaware, has designed a novel reactor that uses highly concentrated sunlight to produce hydrogen from water. The basic idea is to is to create a small, well-insulated cavity and subject it to highly concentrated sunlight. Zinc oxide powder, fed into the cavity, decomposes into zinc vapour […]  Read more »

More Efficient Hydrogen Production

Written by , on February 2, 2012

Researchers at the U.S. Department of Energy’s Argonne National Laboratory have developed an efficient two-step process that electrolyzes hydrogen atoms from water molecules before combining them to make molecular hydrogen. Hydrogen has huge potential applications, especialy in fuel cells, and, even now, approximately 2% of all electric power generated in the United States is dedicated […]  Read more »

New Alloy Can Produce Hydrogen from Water & Sunlight

Written by , on September 1, 2011

Researchers at the Universities of Kentucky and Louisville have determined that an inexpensive semiconductor alloy can be "tweaked" to generate hydrogen from water using sunlight. The team has demonstrated that an alloy formed by a 2% substitution of antimony in gallium nitride has the right electrical properties to enable solar light to split water molecules […]  Read more »

Hydrogen from Cellulosic Biomass

Written by , on May 2, 2011

Researchers at Virginia Tech, Oak Ridge National Laboratory and the University of Georgia have produced hydrogen gas pure enough to power a fuel cell from cellulosic materials (from wood chips) using a mixture of 14 enzymes, one coenzyme and water heated to about 32°C. Jonathan Mielenz, leader of the Bioconversion Science and Technology Group at […]  Read more »

Study: Current Technolgy Could Power the World

Written by , on January 28, 2011

According to a new study by Stanford researcher Mark Jacobson and Mark Delucchi, of the University of California-Davis, by 2030 all new energy generation could come from wind, water and solar, and by 2050, all pre-existing energy production could be converted to renewables, using only technology that is already available and at a similar cost […]  Read more »

Molecular Sponges Soak Up Carbon Dioxide

Written by , on September 14, 2010

A team of researchers at the University of Sydney has developed crystals full of microscopic holes that can capture gases like carbon dioxide. The scientists designed them to be used in facilities like power stations but they could have many other applications such as storing hydrogen or separating methane from nitrogen and carbon dioxide in […]  Read more »

New Bacterium Doubles Hydrogen Production

Written by , on June 12, 2010

Hydrogen can be produced in a way that is carbon neutral by adding bacteria to forestry or household waste in a similar way to that used for biogas production. However, this process does not produce much hydrogen gas for the amount of biomass needed. Now, researchers at Lund University in Sweden have found that a […]  Read more »
