Research fields

The Fraunhofer IEE in Kassel researches for the national and international transformation of energy systems.



Business units

As an applied research institute, we research and develop solutions for the transformation of energy systems and offer a rich portfolio of services, know-how and products.


Joint research under one roof

The time has finally come: it is May 2022 and our employees have moved into the new building. The offices are gradually being occupied and the move is for the most part completed. Some of the laboratories and their infrastructure have been in operation for a while and have already passed the practical test.

Our new Address

Joseph-Beuys-Straße 8

English and Spanish versions of the PtX Atlas published for international use

The map shows the global potential for power-to-X technologies in coastal and inland sites in countries outside the European Economic Area. Now the interactive tool has been published in an English and Spanish version for international use.




HyAfrica investigates natural hydrogen in Africa as an alternative energy source

The HyAfrica project is exploring deposits of natural hydrogen in several African countries to provide alternative energy for local areas. The long-term joint research and innovation partnership between the European Union and the African Union in the field of renewable energy (LEAP-RE) is funding the project with a budget of nearly one million euros. HyAfrica is the first international research project to explore the potential of natural hydrogen as a new energy source.



Green Ammonia for
climate protection: Global PtX Atlas shows potential and costs for export to Europe

Green ammonia is becoming increasingly important in the debate about PtX imports and climate protection. There are good reasons for this, as the effort required to produce and transport the chemical compound is relatively low. Fraunhofer IEE in Kassel has therefore now expanded its global PtX atlas: it now also provides data on the production potential of green ammonia in 97 countries and areas worldwide, and also shows the respective production and transport costs. The PtX Atlas, which is freely accessible online, shows where in the world which quantities of green hydrogen and other PtX energy carriers can be produced and exported to Europe at what cost.



Fraunhofer IEE
reduces forecast
errors for solar eclipse

he integration of photovoltaics into power grids requires increasingly better forecasts, especially with increasing capacities, because uninterrupted grid operation does not accept avoidable errors. In this context, rare meteorological events still present particular challenges. In addition to volcanic ash and Saharan dust, a solar eclipse requires the attention of grid operators, electricity traders and forecasting service providers. At the Fraunhofer Institute for Energy Economics and Energy System Technology IEE, a solution has now been developed to combine the degree of occultation with established weather forecast models specific to the location and time.



Norwegian hydropower in a GHG-neutral Europe: the HydroConnect project

Hydropower is an essential part of the Norwegian energy system. The HydroConnect project is investigating whether and how Norwegian hydropower can contribute to climate protection in Europe. HydroConnect is a collaborative project of the Fraunhofer Institute for Energy Economics and Energy System Technology IEE, the Norwegian research organization SINTEF Energy Research, the Norwegian University of Science and Technology (NTNU) and the University of Trento. HydroConnect is co-funded by the Norwegian Research Council.



Fraunhofer IEE presents Applied Research Solutions for the Energy Industry at E-World 2022

From June 21 to 23, 2022, at the leading exhibition for the European energy industry E-World energy & water 2022 in Essen, Germany, the Fraunhofer Institute for Energy Economics and Energy System Technology IEE presents services and solutions for the energy industry derived from application-oriented research. At the group stand of the Fraunhofer Energy Alliance (Hall 5, Booth 326), Fraunhofer IEE will show know-how from the business units "Analysis and Consulting for Energy Economics”, "Energy Meteorology Information Systems", "Digital Portfolio Management" and "Grid Planning and Operation".



Data4Grid Challenge: Fraunhofer IEE Consumption Forecasts receive an Award

Dominik Jost, Jonas Koch and Dominik Beinert, scientists at the Fraunhofer Institute for Energy Economics and Energy System Technology IEE, have won the Data4Grid Challenge "AI-supported consumption forecasts based on smart meter data". The competition was organized by the German Energy Agency (dena) and umlaut. The results and award ceremony presentation took place at the Future Energy Lab in Berlin on May 4, 2022.



Management of reactive power in distribution grids: Fraunhofer IEE and partners develop new method

With the decentralisation of power generation, distribution grid operators are increasingly required to mobilise reactive power depending on the situation. In the research project "RPC2", Fraunhofer IEE, together with partners from grid operation and the University of Kassel, has now developed procedures with which grid operators can control generation and other plants in the medium and high-voltage level in such a way that they provide reactive power according to demand.
