Energy & storage systems MAN molten salt energy storage (MOSAS) is an economical and flexible technology that can be integrated in various applications. It stores the heat of renewable energies directly, e.g. from concentrated solar power (CSP), or indirectly via electric heaters or heat pumps. The heat is later converted into steam to directly feed the consumer or to power a steam turbine and generate electricity when there is no sunshine or wind. Storage systems based on MAN MOSAS achieve excellent efficiency due to the high operating temperature and heat transfer properties of molten salt. Benefits at a glance – Makes fluctuating renewable energy dispatchable – Long-duration storage technology for renewable energy – Decarbonized power generation – Retrofitting of thermal power plants, e.g. coal-fired power plants – Grid stabilization, peak shaving of volatile electricity – Optimized levelized costs of electricity in combination with CSP technology MAN MOSAS Molten salt energy storage
