The standard model expresses the nuclear forces and QED quite precisely. I know it's very difficult to pull things out of those equations, but fusion has been known quite precisely since the 40's -- thank you Hans Bethe, and the rest of the standard model came along directly.
So, if something is going on here, there had better damned be a theoretical framework to back it up. From the article it sounds like they are just trying things in an ad hoc manner. They get a little extra energy for which they cannot account and they call it whatever they're calling it.
That is what doomed Pons and Fleischman so many years ago. If you cannot say where the extra energy is coming from, or if you say but it overturns established science, you had better damned well have a theoretical basis on which to hang your putative results. Otherwise, it is just what a physicist would call moonshine.
And secret results are not how normal science is done. You have results? Fine! Publish them! Otherwise, you have nothing.
I would be overjoyed about this if it were true, but I am very suspicious. It just doesn't pass the smell test at this time.
