The potential of membrane reactors is enormous. In particular, they could play a key role with endothermic reversible reactions because of the high reactant conversion at low temperature. In the present chapter, current technology status, barriers to be still overcome, and technological/economical perspectives are presented and commented. The main conclusions are that thin Pd layers deposited on porous ceramic substrates by electroless plating or Pd alloy–based films deposited on porous stainless steel (PSS) substrates by Physical Vapor deposition appear to be the most promising membrane, able to reach a hydrogen permeance of 100 Nm3/m2·h·bar0.5 at 500°C. A reasonable price, within 1,500–2,000 € per m2 of thin Pd alloy membranes, could be reached at the end of next decade only if a high cumulative volume of production is reached. The membrane geometry can be either flat or tubular: flat membranes can easily be stacked onto one another by a proper design, making simpler their manufacturing. The issue is to better understand how much surface can be accommodated in a module based on flat membranes.
