Article: Eggshells help make hydrogen fuel.(Research)(The Ohio State University)

ENGINEERS at The Ohio State University have found a way to turn discarded chicken eggshells into an alternative energy resource. The patented process uses eggshells to soak up carbon dioxide from a reaction that produces hydrogen fuel. It also includes a unique method for peeling the collagen-containing membrane from the inside of the shells so the collagen can be used commercially.

L.S. Fan, distinguished university professor of chemical and biomolecular engineering at Ohio State, said he and former doctoral student Mahesh Iyer hit upon the idea when they were trying to improve a method of hydrogen production called the water-gas-shift reaction. With this ...
