Hydrogen Storage in IceCarolyn Koh, Amadeu Sum, Dendy Sloan - Renewable Energy MRSEC, NSF DMR-0820518 If hydrogen is ever going to be used as a fuel, then it must be stored efficiently and safely. A special form of ice grown only at high pressure, as shown in the picture (bottom right), can store hydrogen to be used as a fuel. Professors at the Colorado School of Mines Renewable Energy MRSEC have developed a new method for dramatically improving hydrogen storage in this form of ice. This new method enables hydrogen to be stored in both the small and large cages shown at the tails of the green arrow in the picture. Previously only small cages could store hydrogen. This new synthesis method is critical to improving storage capacities.
