Summary:One approach of Power‐to‐X is the coupling of the energy and chemical sector, using electrolysis for syngas generation and microbial gas conversion for the production of biochemicals. On the verge of commercialization, known challenges of gas fermentation technology are poor mass transfer of syngas, low cell concentration and productivity. These problems can be addressed by an intelligent reactor design. Thus, this article provides an overview on the current state of the art for reactor technology in syngas fermentation and discusses possible concepts with regard to an application at industrial scale. Developing the best reactor possible is important for every biotechnological or chemical process, as it plays a key role in achieving economic success. This study compares different reactor concepts for syngas fermentation, focusing on gas‐liquid mass transfer, power input and scale‐up experiences.
