Low Cost Hydrogen from Water

Written by , on January 14, 2014

Stanford University scientists have developed a low coat, corrosion free silicon-based water splitter comprising a silicon semiconductor coated with an ultrathin layer of nickel. The researchers believe that this could pave the way for large-scale production of clean hydrogen fuel from sunlight. In a water splitter, two semiconducting electrodes are connected and placed in water. […]  Read more »

Jet Fuel from Seawater

Written by , on December 15, 2013

The US Navy is developing a technology that it expects will allow it to produce jet fuel out of seawater. Carbon is abundant in seawater, with the concentration in the ocean being about 140 times greater than in air. Most of the carbon is in the form of bicarbonates with about 1% being carbonates. The […]  Read more »

Technique Could Sequester CO2, Produce H2 and Reduce Ocean Acid

Written by , on June 13, 2013

Scientists at the Lawrence Livermore National Laboratory in California have demonstrated a new technique to remove and store atmospheric carbon dioxide while generating carbon-negative hydrogen and producing alkalinity, which could be used to offset ocean acidification. The team has demonstrated that, when saline water is electrolysed to produce hydrogen fuel and other gases, the acidity […]  Read more »

Low-cost Hydrogen from Any Biomass

Written by , on April 19, 2013

Researchers at Virginia Tech have discovered a way to extract large quantities of hydrogen from any plant, a breakthrough that has the potential to be a low-cost, environmentally friendly fuel source. Associate Proffessor Y.H. Percival Zhang and his team have succeeded in using xylose, the most abundant simple plant sugar, to produce a large quantity […]  Read more »

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 »
