This report offers a comprehensive techno-economic analysis of newly commercial and emerging methane pyrolysis technologies for the production of “turquoise” hydrogen, which can be produced from both fossil and renewable methane sources and produces a carbon byproduct that can be sequestered or displace existing fossil products. Technologies including thermal plasma, uncatalyzed pyrolysis, catalytic pyrolysis, molten metal/molten salt, and non-thermal plasma are covered, and key players within each major route have their technical maturity and processes profiled. Process economics are also provided for thermal plasma processes. The report also includes an analysis of turquoise hydrogen in the context of other low-carbon hydrogen routes.
