The Methodology for Cost-Benefit Analysis of Hydrogen Infrastructure Projects (2024) provides a harmonised framework for assessing investments across the emerging hydrogen value chain, including production facilities, storage, transmission pipelines, terminals, and end-use conversion. It outlines how promoters should quantify capital and operating costs, evaluate system-integration impacts, and assess project viability under evolving hydrogen demand scenarios. Key benefits considered include decarbonisation potential, fuel switching from fossil fuels, improved energy security, sector coupling, and flexibility services for power systems. The methodology distinguishes between monetisable impacts—such as avoided fuel costs and reduced emissions—and non-monetisable ones, captured through qualitative indicators. It emphasises transparent assumptions, cross-border consistency, and robust sensitivity analysis, particularly given uncertainty in hydrogen prices, technology costs, and deployment pathways. Overall, it supports objective and comparable evaluation of hydrogen infrastructure investment proposals.
