Steam methane reforming (SMR) is a method that can be used for producing hydrogen from natural gas. This is achieved in a processing device called a reformer which reacts steam at high temperature with the gas. SMR uses the endothermic reaction

CH4 + H2O ⇌ CO + 3H2.

The reaction is carried out at an activation energy of 206 kJ/mol and temperatures of 500-900 degrees Celsius [3]. In this SMR plant, a COGEN plant is running to export a relatively small fraction of the energy involved to the electricity grid.
