Bockrath describes storage opportunities in the channels of disordered arrays

Based on theoretical and experimental work at the University of Pittsburgh and DOE's National Energy Technology Laboratory, researchers are suggesting that a chemically and physically disordered array of activated carbon nanotubes may provide a solution to hydrogen storage problems. According to NETL senior scientist Brad Bockrath, "The best material for hydrogen storage may not be the ideal nanotube structures frequently assembled in theoretical studies." Bockrath believes that disordered arrays can be activated and engineered to provide molecular nooks and crannies with improved chances of approaching a 6 wt. percent storage target. "Methods for chemical activation are a long way from being exhausted and further experiments will tell us more," said Bockrath.
