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.

 Prof. Kitamura went to a lot of trouble to get permission from the
 publisher to allow a manuscript version of the paper at LENR-CANR.org.
 So let's give it up for the professor and everyone should read this
 paper. It's important. This plus Kidwell and Arata's own recent
 experiments make what I consider and iron-clad case that the Arata
 effect is real. This could well be the most important breakthrough
 since 1989 because it can be controlled and scaled up, so it may lead
 to practical devices.

Great Job by Kitamura et all,

Their conclusion that the D(H)/Pd ratio and absorption energy is an
increasing function of fineness of the sample surface  was airtight based on
the calibrations and differential measurements they document. It confirms
many of the earlier reports by other researchers and gives us a comparative
table of related materials and granularity. It fits with the dimensions of
Mills' skeletal catalysts and Arata's Pd nano material.
