The German Aerospace Center, Deutsches Zentrum für Luft- und Raumfahrt; DLR, has commissioned MAN Energy Solutions to build a molten-salt circuit for its solar-research facility in Jülich in Germany. The plant will help to further improve the process of generating and storing solar energy at very high temperatures. The DLR has already conducted research in Jülich for ten years on Concentrated Solar Power and runs Germany's only solar tower for this purpose. A second solar tower has now been built in which MAN Energy Solutions, among others, will install the molten-salt circuit.

Molten-Salt Energy Storage, MAN MOSAS, uses salt as a storage medium. For this purpose, the salt is first heated to a temperature of, typically, 565°C and then fed into a hot storage tank. The thermal energy can be stored in the tank for several days and – if required at a later date – can be converted back into electricity, for example by means of a steam turbine. During this process, the salt is cooled to around 290°C and is then available for further storage processes in the cold storage tank.

MAN Energy Solutions and DLR have worked together on various contracts since 2001, including engine test stands for Ariane rocket engines at the Lampoldshausen site. For two years now, the DLR and MAN have been jointly involved in the German Federal Ministry of Economics and Energy’s ‘HPMS II’ research project. MAN has already begun developing and manufacturing the solar receiver required for this project.

Based on decades of experience in engineering and the production of molten-salt-cooled reactor systems for the chemical industry at the MAN site in Deggendorf, along with successful cooperation in joint research projects, MAN Energy Solutions won the new order in a Europe-wide tender. The company has now assumed responsibility for the detailed engineering of the molten-salt circuit, its manufacture and installation, as well as its commissioning. The aim is to commercialize molten-salt technology as an important part of the energy transition.
