DOE Project Objectives
Develop an integrated system that directly produces high pressure, high-purity hydrogen from a single unit.
Phase 1:• Task 1: Verify feasibility of the concept, perform a detailed techno-economic
analysis, and develop a test plan (Complete)
• Task 2: Build and experimentally test a Proof of Concept (POC) integrated membrane reformer / metal hydride compressor system (Ongoing)
• POC Performance Targets and Design Basis– Production capacity of 15 Nm3/hr H2
– Hydrogen output pressure of 100 bar
– Hydrogen purity of 99.99%
– Production unit efficiency of >70% and compression efficiency of > 70%
– Unattended operation

Integrate membrane reformer (MRT) & metal hydride c ompressor (MHC, Ergenics)
• Lower capital cost compared to conventional fuel processors by reducing component count and sub-system complexity.
• Increase system efficiency by:– Directly producing high-purity H2 using high temperature, selective membranes;
increased flux due to suction provided by the hydride compressor
– Improved heat and mass transfer due to inherent advantages of fluid bed design
– Equilibrium shift to enhance hydrogen production in the reformer by lowering the partial pressure of hydrogen in the reaction zone
– Using waste heat from reformer to provide over 20% of H2 compression energy
