I personally don't believe a word of it. There are zero credible sources for their claims. The "journal" he published in is not considered reputable. Note that the link to it from the posted article is dead. The correct link is with science replaced with physics. About half of the articles in that "journal" appear to be be about Rossi and Foccardi's nickel battery.
I also read that Rossi was involved in a massive energy scandal some years back and got charged with tax evasion and improper waste disposal.
Here's a little more information, including criticism.

I also cannot see why the site would host a forum and the flamewars about its credibility.
