Power Generation

FRENELL’s technology competes with fossil-fuel power plants in regions with high solar irradiation. The capability of providing Thermal Energy Storage leads to high capacity factors and grid parity which is of prime importance for energy providers and major industrial consumers. Therefore, FRENELL’s technology can provide base load electricity and demand-responsive power input. The technology can be used in greenfield projects as well as to extend new or existing fossil-fired power stations.
Delivering solar power whenever needed.
Enabling multi purpose applications such as combined power and process heat e.g. for Desalination.
Reduces the fossil fuel consumption of a conventional power plant while maintaining the net electric output.


Access to freshwater is vital for human development. In more and more regions of the world, an adequate supply of this precious resource is becoming increasingly challenging. FRENELL DMS® is paving the way for a sustainable source of freshwater.

FRENELL’s DMS® technology can be paired with a desalination solution based on the Multi-effect Distillation (MED) process for the treatment of sea and brackish water. The MED process is characterized by very low energy consumption compared with other thermal processes and is highly reliable and simple to operate. It can be run continuously for up to 24-hour-a-day with minimum operations and maintenance activities or supervision.

Even more value can be added in a cogeneration set-up where the MED process replaces the air cooled condenser in the power application.

MED is highly efficient compared to other thermal distillation methods.
MED operates at low temperature and at low concentration to avoid corrosion and scaling.
MED allows a high tolerance of variations in raw water conditions.

Enhanced Oil Recovery

Thermal Enhanced Oil Recovery (EOR) is a widely used process to increase crude oil extraction of matured oil fields. It is an energy intensive process which mostly uses natural gas to produce steam to be injected in the well.
Instead, FRENELL DMS® Solar EOR uses solar energy to produce steam, eliminating emissions and conserving natural gas for higher value applications.
Delivering steam around the clock speeds up the EOR process.
Guarantees optimum steam parameters at the injection site.
Thanks to the molten salt to water heat exchanger which provides blow down opportunity – scaling and fouling are no issue even for low water quality.
