Future H Drive

Together with the Technical University of Dresden and Deutsche Eisenbahn Service AG (DESAG), WOLF ENERGETIK is investigating the application of FEREDOX® technology as an electricity storage system in overhead line-free rail transportation. In the project, the FEREDOX® technology was scaled up from the test model to an electricity storage capacity of 1 MWh. For this purpose, a reversible high-temperature fuel cell, as a converter from electricity to hydrogen or hydrogen to electricity, is integrated with the iron mass storage unit to form the electricity storage system. The project partners are SolydEra SpA and TEC4FUELS GmbH and EASD Dresden.

The project was successfully completed in September 2024 and has so far received a total of around EUR 3 million in funding from the Federal Ministry for Economic Affairs and Climate Protection.

Test facility for model reactors

In fall 2022, the installation of the pilot plant was completed by integrating the FEREDOX® 10 model reactor and operating it with various FEREDOX® 10 reactors. The set-up is used to test the reaction control and validation of basic process parameters and for the design of storage systems.

Preliminary tests on hydrogen storage using the FEREDOX® process with an HTR test rig

Meaningful data series on the chemical reactions of the process were created for the development work. At the end of 2021, WOLF ENERGETIK set up a high-temperature reactor (HTR) as a test stand at the Freiberg Mining Academy, tested the process and thus demonstrated the key functional properties of the storage material in practice.

The project was supported by the European Union and the Free State of Saxony.
