The experimental data, current development along with simulations as well as future design concepts will be discussed for the annular micro-channel reactor (AMR).  This presentation will encompass design, construction and experimental testing that has been done to date. We will explain how this system could improve the hydrogen production industry using current resources and infrastructure.  Experimental data from different catalyst thicknesses as well as flow rates will be shown.  The AMR is a novel design for an efficient and compact methane-steam reformer to produce hydrogen that is relatively inexpensive to build.  It consists of a tube in tube design with catalyst affixed to the ID of the outer tube. The AMR has the potential to produce hydrogen more directly at fueling stations due to the compact size and cost. The AMR would lessen the need for hydrogen storage as the reactor can be turned up and down to meet current demand. The AMR features a tube in tube design where a micro-channel exists between the two tubes.  This is where a catalytic reaction occurs with the steam and methane to yield hydrogen.  The AMR reforms hydrogen more efficiently than current steam reformers. We will show how this technology is also scalable allowing the AMR to be tailored to the amount of demand it might see. This flexibility is what gives the AMR great potential to be used in many more applications than current steam-methane reformers.
