RENEWABLE ENERGY
Experts join forces to deliver extra efficiency for CSP plants via molten salt

he most important sources of renewable energy, the sun and the wind, are infinitely available – but they do depend on meteorological conditions, the time of day and the time of year. In the future, storage methods that smooth out these fluctuations will therefore play a decisive role in round-the- clock, dependable and efficient supply of energy. Concentrated solar power (CSP) solar-power plants make it possible to charge thermal molten-salt storage tanks with solar energy at rational cost during the daytime and generate power when needed after dusk. Tanks to this “as-needed” power supply, which is independent of the available sunlight, these systems are a key element in the energy turnaround. MAN Energy Solutions and Dillinger are working

jointly on finding answers to the core challenge of the energy turnaround: that of generating large quantities of renewable energy and integrating it intelligently into a reliable electricity and/or steam production system for use in industrial processes. MAN Energy Solutions is a leading mechanical and plant engineering company. Te New Technologies department, under the management of Dr Christian Schuhbauer, devotes itself to the important topics of the generation and storage of electrical energy. A key part is played by steam turbines of up to 180MW output and molten-salt reactor systems. For around four years now, the experience gathered in the field of heat management has also been incorporated into the development of molten-salt receivers for CSP solar-power plants. Te most recent project started is Solar Tower II of the German Aerospace Center (DLR) in Jülich. Dillinger is an integrated iron and steel producer. It is a leader in the field
of tailored-to-application heavy-plate products. Long years of cooperation in pressure-vessel engineering link MAN Energy Solutions and Dillinger. For more than 10 years, the steel producer has been active in the solar-power plant sector, supplying large tonnages of heavy plate and shell courses distinguished by their large dimensions and high individual weights for projects in this field. Tese products are used in steam generators, vessels, reactors and other pressure-bearing equipment of all types. Projects supplied with steel from Dillingen include, inter alia, the CSP solar- power plants of KHI Solar One, in South Africa, Andasol I, in Spain, and GTL Pearl, in Qatar.
