The "anomalous heat effect" is a normal event in the cold fusion phenomenon – On the paper "excess heat evolution from nanocomposite samples under exposure to hydrogen isotope gases" by Kitamura et al. Published in the int. J. Hydrogen Energy43, pp. 16,187–16,200 (2018) –

The anomalous heat effect reported in the paper, "Excess heat evolution from nanocomposite samples under exposure to hydrogen isotope gases" by Kitamura et al. published in the Int. J. Hydrogen Energy 43 , pp. 16,187–16,200 (2018), is investigated in the science of the cold fusion phenomenon (CFP) established in these 30 years. It is concluded that the effect is a normal event in the CFP consistent with many events observed in materials with various components and compositions composed of host elements and hydrogen isotopes. • Cold fusion phenomenon means the nuclear reactions in solids with hydrogen isotopes. • Nuclear reactions occur in solids without any acceleration mechanism. • Excess energy accompanied to the nuclear reaction is useful for an energy source.
