In order to achieve climate neutrality, green hydrogen will play an important role in the future. Technically, it could be produced in many countries around the world. However, the conditions and risks for production vary from country to country. Therefore, challenges of supply security also arise for green hydrogen in case of perspective large import volumes.
In addition to transportation risks and production costs, country risks, which vary from country to country, should also be considered when establishing supply chains. For this purpose, the study evaluates the local conditions of more than 80 countries. So-called EWI Future Energy Scores for the years 2017 to 2021 are calculated based on an extensive data set of country-specific variables. The EWI Future Energy Score enables comparability of potential hydrogen exporters with respect to country-specific factors, consisting of political, economic, social and energy-related sub-indicators. Thus, the EWI Future Energy Score serves as a guide for the selection of potential hydrogen trading partners.
