Concentrated Solar Power Plants
Concentrated solar power plants currently rely on molten salt technology for storing thermal energy. But this is a complex and costly technology. EnergyNest offers promising solution for cost reduction. Parabolic trough plants operating with thermal oil (such as Dowtherm A and Therminol VP-1) will benefit from up to 60% lower CAPEX and up to 75% lower OPEX for their thermal storage system. EnergyNest also offers value that molten salt simply cannot provide – such as its ability to preheat the solar field and turbines, and its capacity to allow continuous plant operation (avoiding shutdown) in case of power block failure.

EnergyNest has developed a unique thermal energy storage (TES) perfectly tailored to concentrated solar power applications. Its performance has been certified by DNV GL, and comes at a lower CAPEX and OPEX versus molten salt systems, largely due to low-cost materials, simplicity and LEGO-like modularity. The system also eliminates the need for external loops between different heat transfer fluids, as well
as costly electrical heat tracing and heaters, thereby further reducing complexity.
