In the journey toward sustainable development and clean energy solutions, hydrogen is expected to play a pivotal role. The growing push toward a hydrogen economy necessitates the development of hydrogen production processes that are not only efficient and economical but also environmentally benign. Recovering hydrogen from hazardous emissions offers dual benefits of pollution control and clean energy. This chapter assesses techno-economics and the life cycle of producing hydrogen using various plasma-catalytic processes, a technique that shows great potential for both environmental safety and financial gains. Beginning with a brief description of plasma catalysis and its application, the chapter details the technical aspects of producing hydrogen by the plasma-catalytic route, delving into the fundamentals and mechanism of the catalytic reaction, process parameters optimizations, technology developments, and technical challenges. The analysis also covers economic aspects, assessing market potential, cost analysis, and economic feasibility in relation to alternative approaches. A life cycle assessment (LCA), which assesses the environmental effects of the process from cradle to grave, is also included in this chapter. This will provide a comprehensive understanding of the environmental sustainability of plasma-catalytic decomposition by taking energy consumption, resource utilization, and emissions into account. The chapter pinpoints the gaps in the literature concerning LCA. It emphasizes clean technology, like the plasma-catalytic route, which offers considerable advantages in terms of efficiency and environmental impact. The chapter concludes with a broader implication for the hydrogen market and recommendations for future research to improve process efficiency, viability, and sustainability to contribute to sustainable development.
