This book offers a pioneering exploration of phase change materials (PCMs), bridging decades of scientific research with cutting-edge technological advancements. Serving as both a comprehensive guide and a catalyst for innovation, it equips researchers, engineers, and sustainability advocates with the knowledge to transform energy systems amid the urgent challenges of climate change. 

This book guides readers through the evolving history of PCMs, from Alan Tower Waterman’s 20th-century experiments to modern breakthroughs in nanotechnology and composite materials. It demystifies the science of latent heat storage, providing rigorous analyses of organic, inorganic, and eutectic PCMs while addressing critical challenges such as thermal conductivity limitations and phase separation. Blending theory with practical application, the work presents detailed case studies spanning solar energy integration, electronic cooling, sustainable building design, and thermal solutions for space exploration.
