Display MoreOn some blog discussions it's been suggested that nickel does not have any significant hydrogen adsorption capability [1] and that the bulk absorption of hydrogen at atmospheric pressure is very small compared to Palladium, with a maximum H/Ni atomic ratio of about 0.001 at 1500°C [2, 3]. Putting aside any possible correlation with observed LENR effects, I've always assumed that H adsorption of Ni was significant and could have been maximized by increasing exposed surface area. It looks like I was wrong.
Can more informed people add some sources to scientific papers confirming or refuting this?

The paper you site in [1] is from 1934 (NB: I have only read the abstract). Not to say that they could test this properly back in 1934, but perhaps the conditions were vastly different for the Nickel.
In Sankaranarayanan, T.K., et al.'s paper from 1995 there is an absorption and loading discussion that is interesting, relating to this.
Check also the references in that paper this paper and the statement
"Hydrogen is known to dissociatively adsorb on Ni(111) with a low barrier to reaction, although large exposures are necessary to (nearly) complete saturation " and the two references to support that claim:
