This is how the newly designed Molten Salt Storage system works for SOLARX

How do we reap the advantages of using energyPRO?

To ensure the effectiveness and optimization of Molten Salt Storage, the SOLARX partner EMD International has recently created a model of this process in energyPRO. This model enables us to assess operational income, electricity generation by specific units, storage capacity, and CSP consumption.

Where is this model applied?

Within SOLARX, energyPRO is utilized for modeling and sizing the heliostat field and three types of receivers for concentrating solar power: PV-production, thermal heat production (for heating molten salt), and hydrogen production, although the latter is currently not integrated into this energyPRO model.

It represents a method for storing energy generated from renewable sources like solar power plants or wind farms, forming part of the solution offered by EMD International. In such a system, a blend of molten salts serves as the medium for storing and releasing thermal energy. Here’s an outline of its typical functioning:

Here’s how it typically works:

Heat Collection: The molten salt mixture is heated either through renewable electricity via an electric heater or through concentrated sunlight directly converted into heat in a specially designed receiver.

Energy Storage: Heated molten salt is then stored in insulated tanks, retaining its heat energy for future use. Salts chosen for these systems possess the ability to maintain heat over extended periods without significant loss.

Energy Release: When electricity demand arises, the stored hot molten salt is pumped through a heat exchanger. Heat is transferred from the molten salt to a working fluid (such as water or steam), driving a turbine to produce electricity.
