Nope. Those sources are ruled out. Pd-D LENR produces helium in the same ratio to the heat as D+D fusion, so it is fusion.
If you don't believe that, you are wrong.
I do not know whether Ni-H LENR exists, but if it does, it is likely to be H-H fusion. I do not believe there are different, unrelated reactions going on with metal hydrides. That would violate what McKubre calls the conservation of miracles.
PP fusion cannot produce any appreciable energy level at room temperature. You are wrong.
