I'm not sure I understand the conclusions of this paper. It appears that they found a very large heat of absorption of *either* H or D into Pd and Pd-Zr powders, but that by itself, while interesting, doesn't seem to lead anywhere, as you presumably have to give that heat back in order to get the H or D back out of the lattice. Right? Isn't that exactly analogous to the heat gain when dissolving certain salts? It's borrowed, not bought. Or did I misunderstand that?
On the other hand, the last line of the conclusion seems like the payoff: " The sample charged with D2 also showed significantly positive output energy in the second phase after the deuteride formation." That's in a discussion of the Pd-Zr results, and it presumably relates to the last two lines of table 1, in which we see that average output energy of the second phase of the experiments with PZ as being: (D) 4.8 +/- 3.0 kJ (H) -1.1 +/- 3.6 kJ That seems to imply that, if we assume the energy output is actually positive or zero, then for H they saw something between 0 and 2.6 kJ, and for D they saw something between 1.8 and 7.8 kJ. So, if there really was no difference between D and H (which is apparently not ruled out by the results), then the output must have been between 1.8 and 2.6 kJ. That's a bit less than half the energy produced in the first phase.
