The paper discusses catalytic methane decomposition (CMD) as a technology to produce hydrogen without associated CO2 emissions. CMD utilizes transition metal catalysts, such as nickel, iron, and cobalt, to break down methane into hydrogen gas and solid carbon at temperatures between 450-750°C, which are lower than the reaction's natural temperature due to catalysis. Despite its benefits, CMD faces the challenge of rapid catalyst deactivation caused by carbon accumulation. Strategies to combat this include the use of bimetallic catalysts, optimized catalyst supports, catalyst regeneration, and novel reactor designs like fluidized bed reactors. The STORMING project aims to enhance CMD technology by integrating advanced reactor designs. The paper discusses different reactor configurations such as plasma reactors, molten metal reactors, and membrane reactors. Fluidized bed reactors show promise for industrial-scale hydrogen production, balancing methane conversion, catalyst stability, and ease of carbon removal. Techno-economic analyses suggest that CMD hydrogen production costs could be competitive with steam methane reforming, especially when considering carbon taxes. CMD could also achieve carbon-negative hydrogen production using biogas or synthetic methane. The carbon byproduct has economic value as well, especially if carbon nanostructures are produced. CMD could significantly contribute to providing low-cost, low-emission hydrogen in various sectors. Its ability to leverage existing natural gas infrastructure while reducing emissions positions CMD as a potential key player in the transition to renewable hydrogen sources and achieving climate targets.
