Scientists at the University of Delaware say they have developed a new hydrogen storage method-carbonized chicken feather fibers; that can hold vast amounts of hydrogen.
“Carbonized chicken feather fibers have the potential to dramatically improve upon existing methods of hydrogen storage and perhaps pave the way for the practical development of a truly hydrogen-based energy economy,” says Richard P. Wool, professor of chemical engineering and director of the University's Affordable Composites from Renewable Resources (ACRES) program.

  The research was presented by Erman Senoz, a graduate student in UD's Department of Chemical Engineering.Chicken feather fibers are mostly composed of keratin, a natural protein that forms strong, hollow tubes. When heated, this protein creates crosslinks, which strengthen its structure, and becomes more porous, increasing its surface area. The net result is carbonized chicken feather fibers, which can absorb as much or perhaps more hydrogen than carbon nanotubes or metal hydrides, two other materials being studied for their hydrogen storage potential, Wool says. Plus, they're cheap.Using carbonized chicken feathers would only add about $200 to the price of a car, according to Wool. By comparison, making a 20-gallon hydrogen fuel tank that uses carbon nanotubes could cost $5.5 million; one that uses metal hydrides could cost up to $30,000, Wool says.
