Interesting hydrogen storage option

I have heard of many different type of storage solution to create a hydrogen powered vehicles, but the idea of using chicken feathers to store the molecule is one that surprised me. On Saturday morning, a segment on NPR was discussing the idea, originating out of University of Delaware in Newark. The idea is similar of how carbon Nano structures are able to trap different molecules with a protein called keratin[see fig. 1]. This protein when boiled tightens into a web structure able to trap the H2. Though still in testing theory phase the idea has much going for it: the structure can possibly store more hydrogen, than carbon nanotubes, and the cost would hover only around $200, compared to carbon nano tubes at $5.5 million, and many hydrides coming in at $20,000-$30,000. Alought cheap, and plentiful materials the volume required would become a serious issue. More information with the main article is in link below
