The Heatcube technology differs from traditional thermal energy storage (TES) methods in several key ways:
Key Differences
-
Molten Salt Composition:
- Heatcube: Uses a combination of three salts, which provides a lower solidification temperature of about 131°C. This is significantly lower than the traditional CSP salts that solidify at around 290°C.
- Traditional CSP: Typically uses two salts with higher solidification temperatures.
-
Temperature Range:
- Heatcube: Operates within a temperature range of 170°C to 500°C, allowing for a broader range of industrial applications.
- Traditional CSP: Generally has more limited temperature ranges.
-
Charging Mechanism:
- Heatcube: Employs resistive heating technology to convert electricity into heat, which is stored in molten salts. This method is efficient, with up to 90% efficiency.
- Traditional CSP: Often uses solar radiation as the primary heat source.
-
Modularity and Flexibility:
- Heatcube: Offers a modular design with tanks capable of storing 8MWh each, adaptable for various industrial processes. It can supply heat in the form of steam, hot air, or thermal oils.
- Traditional CSP: Typically designed for large-scale solar power plants and less adaptable for diverse industrial applications.
-
Efficiency and Flexibility in Charging and Discharging:
- Heatcube: Can charge and discharge simultaneously, allowing continuous heat supply without interruption and enabling participation in frequency reserve markets.
- Traditional CSP: Generally has fixed charging and discharging cycles based on solar availability.
-
Integration and Scalability:
- Heatcube: Designed as a plug-and-play system, easily integrated into existing industrial processes and scalable up to 120MWh total capacity.
- Traditional CSP: Often requires extensive setup and infrastructure, making it less scalable for smaller-scale industrial applications.
Overall, the Heatcube’s innovative use of molten salt composition, efficient charging mechanism, modular design, and flexible output options make it a more versatile and efficient solution for industrial thermal energy storage compared to traditional methods.
