Typically cold fusion has always been self-referential: it has shaped the chemistry and physics it needs, considering the generally accepted science as inadequate to explain the mechanisms of its claimed reactions.
Mats Lewan offers an eminent example of this surprising cultural self-sufficiency.
I will try here to comment upon a few Mats’ statements but, in order not to fall into the same fault, I’ll quote two treatises of Advanced Inorganic Chemistry, from Interscience Publishers and Oxford University Press, possibly excluding my own opinion.
1. The first step is to expose a transition metal to hydrogen. Nickel is for various reasons the best choice of transition metal, but any transition metal should do.
2. Next step is to obtain H- ions, i.e. hydrogen atoms with one extra electron. To do this, Piantelli heats the system to a certain temperature and also uses a certain pressure to control formation of H+ and H- ions when splitting hydrogen molecules, H2.
H- ions are very energetic; they can only be obtained in severe conditions. See:

The hydrogen atom can gain an electron to form the hydride ion H− with the
helium electronic configuration
H + e− → H− ΔH = 72.8 kJ/mol.
With the exception of beryllium, all the elements of Groups 1 and 2 react
spontaneously when heated in hydrogen gas to give white solid hydrides. The chemical and physical properties of these solid hydrides indicate that they are ionic compounds.
In the E-Cat, hydrogen is provided through lithium aluminium hydride, LAH, which when heated transforms into hydrogen gas, aluminium and LiH, the latter consisting of Li+ and H- ions, making it an effective source of H-.
Ion H- cannot in any way be set free. It only exists in the lattice of LiAlH4. Thermal decomposition of the salt only produces H2. LiH decomposes into neutral elements, without freeing H-.
This invention by Rossi, described in his patent, should be one reason that he has managed to achieve much higher power yield from the process, but it should be noted that Rossi until the second generation E-Cat reactor—the Hot Cat in 2012—used hydrogen from a canister (and maybe had another method for generating H-, even without knowing it).
Note: Some suggest that the H- concept might refer to a different form of hydrogen, akin to Randell Mills (CEO, founder of BLP) concept of hydrino, or Swedish researcher Leif Holmlid’s concept of ultra dense deuterium.
Hydrino and ultra dense deuterium only belong to the cold fusion self-referring literature. No trace of them are present in the data bank of accepted literature.
Mats, let me say that writing down theoretical models is very easy, as long as you refuse to test their validity by comparison with the generally accepted science.
Your model matches the E-Cat that nobody has ever seen, apart from its tinfoiled version tested on 14 January 2011. Both the theoretical model and the real version do not work; they are close to voodoo science.
