Chapter 9: Solar thermal energy and its conversion to solar fuels via thermochemical processes

This chapter reviews the conversion of solar energy to various fuels through the use of thermochemical processes. The chapter begins with an overview of solar thermal technologies capable of providing the necessary energy at appropriate temperatures, before summarizing the sometimes bewildering range of process options. As many hundreds of potential cycles have been proposed over the years, the chapter will necessarily focus on groups of reaction schemes with common characteristics. It will also endeavor to provide the reader with an up-to-date summary of research and demonstration activities around the world, along with a summary of some of the priorities for further work
