Cover Story: Hydrogen is increasingly being viewed as the preferred long-term transportation energy carrier and a means of reducing anthropogenic carbon dioxide emissions into the atmosphere. This realization has led to an increased impetus for the development of more efficient and intensified hydrogen production processes. The illustrated membrane storage reactor represents a novel process that can broaden the operating window of steam methane reforming, overcome its equilibrium limitations and separate the hydrogen product in situ. Its illustrated cyclic operation can transform methane (grey) into hydrogen (blue) utilizing water (green) both as a reactant and as a separating medium. View this paper
