University of Chicago Scientists Find New Way to Store Hydrogen Fuel

New hydrogen-water compound could solve storage problem

N class=BTX>University of Chicago scientists have proposed a new method for storing hydrogen fuel in this week's online edition of the Proceedings of the National Academy of Sciences.

The lack of practical storage methods has hindered the more widespread use of hydrogen fuels, which are both renewable and environmentally clean. The most popular storage methods-liquid hydrogen and compressed hydrogen-require that the fuel be kept at extremely low temperatures or high pressures.

But the University of Chicago's Wendy Mao and David Mao have formed icy materials made of molecular hydrogen that require less stringent temperature and pressure storage conditions.

"This new class of compounds offers a possible alternative route for technologically useful hydrogen storage," said Russell Hemley, Senior Staff Scientist at the Geophysical Laboratory of the Carnegie Institution of Washington. The findings also could help explain how hydrogen becomes incorporated in growing planetary bodies, he said.
