The depletion of conventional energy resources necessitates the exploration of alternative energy sources, such as solar, wind, geothermal, and bio-gas. However, these renewable options have limitations in different climatic conditions and require large land areas for installation, while their output efficiency remains comparatively low. To address this challenge, the study of Low Energy Nuclear Reactions (LENR) presents a promising avenue for green, clean, portable, and sustainable energy. The Centre for Energy Research (CER) at S-VYASA University, Bangalore, India, has actively pursued LENR research for the past 9 years. Research groups have observed that the absorption of hydrogen into metal lattices is a crucial condition for LENR to occur. Various research groups, including CER, have explored metals like nickel, platinum, titanium, and palladium for high levels of hydrogen loading at controlled temperatures and pressures. In this study, two identical reactors were fabricated, one with an active fuel component and the other serving as a control unit. Both reactors underwent identical processes and hydrogen loading protocols. The active reactor consistently exhibited higher skin temperatures compared to the control reactor under the same power input, indicating the generation of excess heat. The experiment ran continuously for three months, showcasing sustained excess temperatures. (c) 2023 ICCF. All rights reserved. ISSN 2227-3123
