Advanced H2 membrane technologies have the potential to improve the cost and efficiency of future power plants for H2 production and/or CO2 capture. In this chapter, the types of membrane materials used for hydrogen separation are first presented. Membrane engineering issues follow, with focus on membrane system design and performance. Possible integration schemes of H2 membrane systems in power plants are then discussed. Hydrogen storage and transportation issues are also briefly covered. Finally, future trends and further sources of information are commented upon at the end of the chapter.
