Global Outlook for Turquoise Hydrogen

Low-emission hydrogen can be an important contributor to the decarbonization of different sectors of the economy in different regions of the world. While green and blue hydrogen have being extensively studied, the potential of methane pyrolysis (“turquoise hydrogen”) is less explored, especially with respect to applications of solid carbon produced during the methane conversion process. Detailed analyses at a global and regional level are needed to: quantify the economic and technological potential for innovative approaches in methane pyrolysis; assess the magnitude of new applications for solid carbon (e.g., construction materials, replacing metallurgical coke in steel production, soil amendment); determine if new applications would lead to long-term storage of carbon; evaluate the implications of replacing concrete in buildings with new construction materials based on solid carbon; and develop realistic pathways for decarbonization at regional and global scales.
