p As automakers ramp up their plans to put greener vehicles on the road, hydrogen storage has become a pivotal issue. Whereas its been suggested that graphene could play an important role in retaining hydrogen for use in fuel cells and other technologies, a team of researchers at the National Institute of Standards and Technology (NIST) and the University of Pennsylvania in Philadelphia say theyve found a way to configure graphene that enables it to hold 100 times more hydrogen molecules than a single layer of the carbon-based substance. a href=http://www.scientificamerican.com/blog/post.cfm?id=graphene-used-to-make-a-hydrogen-mo-2010-03-19[More]/a
