http://www.nsf.gov/news/news_summ.jsp?cntn_id=108390&org=NSF&from=newsUsing corncob waste as a starting material, researchers have created carbon briquettes with complex nanopores capable of storing natural gas at an unprecedented density of 180 times their own volume and at one seventh the pressure of conventional natural gas tanks.
The breakthrough, announced today in Kansas City, Mo., is a significant step forward in the nationwide effort to fit more automobiles to run on methane, an abundant fuel that is domestically produced and cleaner burning than gasoline.
Supported by the National Science Foundation (NSF) Partnership for Innovation program, researchers at the University of Missouri-Columbia (MU) and Midwest Research Institute (MRI) in Kansas City developed the technology. The technology has been incorporated into a test bed installed on a pickup truck used regularly by the Kansas City Office of Environmental Quality.
The briquettes are the first technology to meet the 180 to 1 storage to volume target set by the U.S. Department of Energy in 2000, a long-term goal of principal project leader Peter Pfeifer of MU.
