Abstract

Climate change necessitates the expansion of renewable energy systems, and sustainably produced hydrogen plays an important role in this expansion. For widespread use, there is a need for efficient hydrogen storage technologies. Ammonia facilitates the reversible storage of hydrogen, with the conversion occurring in catalytic reactors. This review proposes an integrated approach to enhance the efficiency of catalytic reactors through multi-material additive manufacturing (MMAM). It includes material development, process technology, and component design for both directed energy deposition and powder bed fusion MMAM processes. In this review, the current state of the literature in these areas is summarized, and the research needs are identified.
