Learn about the pioneering work being done at BNL in the field of hydrogen storage as Jason Graetz of the Energy Sciences & Technology Department presents the 433rd Brookhaven Lecture, "Fueling
Up With Hydrogen: New
Approaches to Hydrogen Storage."

| Speaker: | Jason Graetz, Ph.D., Energy Sciences & Technology Department | | Host: | Brant Johnson and Fulvia Pilat | | Date: | Wednesday, February 20, 2008 | | Time: | 4:00 PM | | Abstract: | Hydrogen, the most abundant element in the universe,
burns excellently and cleanly, with only pure water as a byproduct. NASA has used hydrogen as fuel for years in
the space program. So, why not use hydrogen to fuel cars?
The bottleneck of developing hydrogen-fueled vehicles has been identified: the greatest problem is storage. The conventional storage method, compressed hydrogen gas, requires a large tank volume, and the possibility of a tank rupture poses a significant safety risk. Another method, low temperature liquid storage, is expensive
and impractical for most automotive applications. An alternative is to store the hydrogen in the solid state.
In his talk, Jason Graetz will describe the new approaches to hydrogen storage being studied by his group at BNL. These include using kinetically stabilized hydrides, bialkali alanates and reversible metal-organic hydrides. The researchers are also using novel synthesis approaches,
state-of-the-art characterization and first principles
modeling, all providing a better fundamental understanding
of these interesting and useful new materials. |
