Book

Solar-driven CO₂ methanation offers a promising route for integrating renewable energy with carbon dioxide utilization and synthetic methane production. However, translating advances in catalytic materials into industrial applications requires a comprehensive understanding of reaction mechanisms, reactor performance, process integration, and economic feasibility. This book explores the fundamental principles and technological developments of CO₂ methanation, covering thermocatalytic, photothermal, and photocatalytic pathways. Particular attention is given to catalyst performance, reaction engineering, hydrogen supply, thermal management, and the challenges associated with industrial scale-up. The discussion extends to the integration of methanation technologies with ammonia–urea production facilities, highlighting the importance of realistic carbon dioxide availability, renewable hydrogen requirements, and system-level energy balances. By connecting scientific understanding with engineering and sustainability considerations, the book examines technology readiness, techno-economic performance, life-cycle implications, and the requirements for future industrial deployment. This volume is intended for researchers, postgraduate students, chemical engineers, and professionals working in catalysis, renewable energy, carbon utilization, and sustainable industrial technologies.
