To meet Europe\u2019s demand for green hydrogen, governments and the private sector have high hopes for production in Africa. Imports without guarantees are not competitive.<\/p>\n\n\n\n

A study led by the Technical University of Munich (TUM) has now shown that the financing costs for production facilities in African countries would be much higher than previously assumed. Only 2 percent of around 10,000 investigated locations would be competitive for exports to Europe. This would require price and offtake guarantees from European governments.<\/p>\n\n\n\n

Green hydrogen is considered an important component for climate-friendly industrial production, for example in the steel industry. Hydrogen is regarded as \u2018green\u2019 when the electrolysis used to produce it is powered by renewable energy sources. Because Europe is unlikely to be capable of meeting its own needs, the focus has increasingly shifted to Africa in recent years. Governments and the private sector have high hopes that production sites for export could be developed in African coastal countries with favorable conditions for solar and wind power. The first projects are currently being planned, although most plants are still in the concept development stages.<\/p>\n\n\n\n

When analyzing these projects, researchers at TUM, the University of Oxford and ETH Zurich observed that the cost estimates were highly imprecise in many cases. \u201cMost of the conventional models for green hydrogen plants typically use uniform financing costs. However, the investment environment is different in every country and is subject to especially high risks in many African countries,\u201d says Florian Egli<\/a>, who holds the Professorship for Public Policy for the Green Transition at TUM.<\/p>\n\n\n\n

Consequently, the research team developed a new method for calculating the financing costs of green hydrogen production facilities, in other words the costs to the plant operators for raising capital for their investments. This takes into account the specific conditions for hydrogen production in 31 African countries such as transportation and storage options and the degree of legal certainty and political stability. The model assumes that the production plants will be operational by 2030 and that the hydrogen will be converted into ammonia and shipped to Rotterdam.<\/p>\n\n\n\n

Price of around \u20ac3\/kg only with guarantees<\/h4>\n\n\n\n

The study<\/a> examines four scenarios in which general interest rates are either high or low and in which either the plant operators assume all investment risks or policymakers issue price and offtake guarantees for the green hydrogen. The research team\u2019s calculations show that, in the current interest rate environment, the operators would have to pay around 8% interest on their financing at best, but possibly as much as 27%, depending on the scenario and country. Most existing models had assumed a range of 4\u20138%, however.<\/p>\n\n\n\n

On that basis, the research team calculated the overall production costs in Africa and the price of green hydrogen exported to Europe. If the operators had to bear the investment risks alone at an interest rate corresponding to the current situation, the lowest possible price of hydrogen on the continent would be just under \u20ac5\/kg. In the case of guarantees by European governments and lower interest rates, the lowest possible price would decrease to a good \u20ac3\/kg. Even under these highly favorable conditions, African countries would face tough competition from other regions. For example, in a European Hydrogen Bank auction of subsidies for green hydrogen projects in Europe in 2024, the lowest price of a successful bid was below \u20ac3\/kg.<\/p>\n\n\n\n

\u201cProducing green hydrogen in Africa for export to Europe is much more expensive than previously believed,\u201d says Stephanie Hirmer, a professor of climate compatible growth at the University of Oxford. \u201cThe past price calculations have not adequately reflected the socio-political risks.\u201d<\/p>\n\n\n\n

Around 200 locations with potential for competitive production<\/h4>\n\n\n\n

The research team applied its model to more than 10,000 locations. Assuming that price and offtake guarantees are provided, only around 200 locations would come close to a price of \u20ac3\/kg at today\u2019s high interest rates and would therefore have the potential of achieving economic competitiveness by 2030. These locations are in Algeria, Kenya, Mauritania, Morocco, Namibia and Sudan. However, the study was only able to incorporate security risks at the national level. Because many otherwise optimal sites are located in insecure regions, the number of potentially competitive sites could be further decreased.<\/p>\n\n\n\n

\u201cAfrican production locations can be competitive for exports to Europe only if the European countries guarantee that they will purchase certain quantities of hydrogen at fixed prices,\u201d says Florian Egli. \u201cLoan default guarantees such as those provided by the World Bank would also help. Only with policy instruments of this kind will it be possible to establish trade in green hydrogen from Africa to Europe, which might result in lower costs over time.\u201d<\/p>\n\n\n\n

Regardless of the cost issue, the researchers see stable agreements as a prerequisite for an industrial and development policy of African states geared to long-term success. \u201cIt\u2019s also about fairness,\u201d says Stephanie Hirmer. \u201cIf the current hype is not backed up by meaningful political measures, we risk seeing projects developed that are neither cost-effective nor create added value for local populations.\u201d<\/p>\n\n\n\n
