In summary, it is clear that vigorous basic research programmes on catalysts and on membrane separation processes should be instigated if hydrogen from fossil sources is to reach its full potential and become cost-effective. Similarly, further investigation is necessary to define the optimum conditions for the direct conversion of wet biomass to hydrogen. Sequestration of carbon dioxide, which is another important topic for research, is discussed in the following chapter. 

In Chapter 10 a deeper analysis related to the integration of inorganic membranes in IGCC and carbon capture and sequestration (CCS) plants for power or hydrogen production is presented. To avoid a lack of information, in this chapter the investigation related to the integration of polymeric membranes to separate H2-CO2 gas mixtures produced in an IGCC power plant is also considered.
