The field of condensed matter nuclear science originated in 1989 with Fleischmann and Pons’ electrolysis of Pd with heavy water. However, anomalous heat generation and other related phenomena were observed not only by electrochemical methods, but also by loading of deuterium or hydrogen in metals such as Pd and Ni. In this paper, we will first give a short overview of the progress in these gas loading type experiments. After that, we will describe the recent progress of our research team. The authors have been studying energy generation using nano-sized multilayer metal composites with hydrogen gas. Two nano-sized metal multilayer composite samples, which were composed of Ni, Cu, and other thin films on bulk Ni (25 mm × 25 mm × 0.1 mm), were used. These samples were fabricated by the Ar ion beam method, or by the magnetron sputtering method. Heat bursts and excess energy generation were observed during the experiments under vacuum conditions (<10−4 Pa) using nano-sized metal multilayer composites on Ni substrate and hydrogen gas. Released energy normalized to the total amount of absorbed hydrogen reached 16 keV/H or 1.5 GJ/H-mol. Sometimes spontaneous heat bursts were observed. This suggests that the burst heat release reactions occurred in the near surface region of the nano-sized multilayer metal composite. Furthermore, we have succeeded in intentionally inducing heat bursts, based on the observations of the spontaneous heat bursts. By measuring the optical spectrum emitted from the sample, we detected a simultaneous increase in mid infrared radiation flux when a heat burst occurred.
