This book examines the role of global energy technology in addressing climate change. The book considers the nature of the climate change challenge and the role of energy in the issue. It goes on to consider the implications for the evolution of the global energy system and the potential value of technology availability, development and deployment. Six technology systems are identified for special consideration: CO2 capture and storage, Biotechnology, Hydrogen systems, Nuclear energy, Wind and solar energy, and End-use energy technologies. In addition, consideration is given to the role of non-CO2 gases in climate change as well as the potential of technology development and deployment to reduce non-CO2 emissions. Present trends in energy R&D are examined and potentially fruitful avenues for research. The book concludes with a set of key findings.
