If you haven't already seen it, skip to about 5:30 in for George Mileys talk on what his group is up to (or 14:00 to get to gas loading stuff): http://www.youtube.com/user/kiholobay#p/u/2/N1m2wQevFAY getting about 350W/kg out of Pd-Zr nanopowder, 4bar D2 gas loading, room temp. Claims no problems with reproducibility now. Looking to elevate temp and pressure (increases rates) and Investigating other materials.
