Economics of Hydrogen

Robinius et al. provide valuable information needed for a discussion of the potential role of hydrogen for decarbonizing energy systems. They first discuss major technical and economic characteristics of hydrogen supply systems, followed by potential end-use applications of hydrogen fuels of different origin (“color coding”), fuel supply cost estimates, and an overview of the various hydrogen production, supply, and storage options. Hydrogen-related policy and regulatory aspects are discussed as well as safety and public acceptance issues. Finally, it deals with the willingness to pay of consumers for different alternative fuel vehicle characteristics. The review concludes by arguing that “green hydrogen” is widely accepted among consumers, that costs are expected to decline rapidly with the market diffusion of hydrogen technologies, and that policymakers’ and business interest is presently on the rise.
