The aim is to develop and demonstrate a new, magnesium hydride-based heat storage system for high-temperature applications that has a significantly higher storage density than conventional storage systems.
The thermal discharge of the heat accumulator is based on the reversible, exothermic reaction of magnesium with hydrogen with the formation of magnesium hydride. During this reaction, heat is released at approx. 400 ° C. In the reverse reaction, the decomposition of magnesium hydride into magnesium and hydrogen, heat is required, which means that the heat accumulator is charged.
Such systems can also be operated as power-to-heat storage systems, which can make a significant contribution to making the power grid more flexible if the proportion of renewable energy continues to rise in the future. If required, the stored heat can then be returned to energy use as high-temperature heat with almost no loss.
Based on the know-how of the partners IUTA and MPI, who have already implemented similar but smaller systems on a laboratory scale, Martin Busch & Sohn GmbH (MBS) will develop an innovative 250 kWh heat storage system on a pilot plant scale, which is based on a plate heat exchanger.
The development of the overall system with heat supply and removal, the coupling with a hydrogen storage unit required for operation and the integration of the system at a location with an existing, suitable infrastructure (user center h2herten) are carried out by the Westphalian Energy Institute of the Westphalian University of Gelsenkirchen (W ‑ HS ) carried out.
In the demonstration mode, the operating and long-term behavior of the heat storage system is examined and the energetic efficiency and the control behavior (dynamics) of the individual functional units and the overall system are determined.
The state of North Rhine-Westphalia and the EU are providing funding of € 2.4 million to implement this project
