New Fuel Cells Could Cost 90% Less

Written by , on August 27, 2013

Redox Power Systems, a startup based in Fulton, Maryland, plans to bring to market a fuel cell that is about one-tenth the size and one-tenth the cost of currently commercial fuel cells by 2014. The company's first product will be a 25-kilowatt generator about the size of a dishwasher, that Redox says produces enough electricity […]  Read more »

Affordable Storage of Energy As Hydrogen

Written by , on April 10, 2013

Researchers at the University of Calgary have reported, in the journal Science, that they have developed a way to make new affordable and efficient catalysts for producing hydrogen and oxygen from water and electricity for storage and subsequent power generation. Current electrolyzer devices use catalysts to drive a chemical reaction that converts electricity into chemical […]  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 »

Producing Energy by Treating Waste Water

Written by , on August 13, 2012

Israeli company, Emefcy, has developed a microbe-based technology that harvests energy while treating waste water. The process starts with the same principle as most wastewater treatment – water is aerated so that bacteria in the liquid breaks down organic material. But instead of using electricity to push air into the water, Emefcy uses a permeable, […]  Read more »

New Catalyst Could Lower Cost of Fuel Cells

Written by , on July 17, 2012

Engineers at the University of Wisconsin-Milwaukee have identified a catalyst that provides the same level of efficiency in microbial fuel cells as the currently used platinum catalyst but at 5% of the cost  – the discovery may lead to much more affordable energy conversion and storage devices. In microbial fuel cells, colonies of bacteria feed […]  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 »

Vitamin Boost for Fuel Cells

Written by , on December 8, 2011

Scientists at the Institute of Atomic and Molecular Science in Taiwan have reported that a carbon-based catalyst loaded with vitamin B12 showed promise as a low-cost alternative to platinum in fuel cells. In order to generate electricity, hydrogen fuel cells require an oxygen reduction reaction at the cathode together with an oxidiztation reaction (producing water) […]  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 »
