An accessible reference requiring minimal chemistry background, this work offers insight into the chemical processes used in emerging technologies to achieve sustainable energy production. It examines the catalytic processes involved in the transformation of bio-based feedstock into clean and economically attractive products and highlights how this technology can be used for waste management solutions, particularly in the synthetic polymers industry. Next, the authors discuss the promise of hydrogen-based and fuel cell-based technologies. The text surveys currently available commercial technologies and includes real-world case studies of renewable energy projects in Asia and South America.
