Green Hydrogen

The following case studies were carried out with companies that have developed demonstration projects and/or are in the process of developing large-scale projects, in order to shed light on the success factors of pioneer green hydrogen projects.

Case studies were selected from emerging and developing countries wherever possible, or from developed economies where the former can take advantage of key learnings. Selected projects and companies cover several end applications for green hydrogen, including industry, transport and energy applications.

The company case studies have been informed by background desk-based research covering the companies’ publicly available information. In order to gather additional information and insights on the green hydrogen projects, semi-structured interviews were conducted with the relevant company representatives. Subsequently, the case studies prepared by the OECD were vetted by the companies ahead of their publication.

In 2023, the OECD released a new Working Paper on the Financing cost impacts on cost competitiveness of green hydrogen in emerging and developing economies. This working paper utilises financial market data to address the knowledge gap concerning the range of Weighted Average Cost of Capital (WACC) for green hydrogen projects. It also conducts a survey among investors and financiers to identify key risk factors contributing to the high WACC.
