Thermal energy storage (TES) and Concentrating Solar Thermal (CST) systems are one of the most promising technologies for harnessing solar energy and renewables in general.
The production and storage of renewable energy is a top challenge for mankind.
These technologies make it possible to make stable and continuous a source within its natural state is not, because it is subject to diurnal cycles and climate change.
Not all thermal storage technologies have the same potential, performance, and allow continuous charging and discharging of energy.
MAGALDI TECHNOLOGIES DO.
The key element of Magaldi Green Energy cutting-edge technologies is the silica sand fluidized bed (FB) as thermal energy storage medium.
Fluidized solid particle bed technology
Solid particles, used as heat transfer fluid (HTF) material, allow:
- Higher temperatures (>1000 ˚C) than molten salts;
- Direct heating of particles;
- No freezing or decomposition;
- No costly heat tracing.
TES Charge/Discharge
Fluidized bed ON
- High Thermal Diffusivity ~1 x 10-3 [m2/s]i.e., 1000 times higher than concrete, rocks, gravel etc.
- Fast Response Time
TES stand-by mode
Fluidized bed OFF
- High Thermal Insulation
- Long duration energy storage
- Minimum heat losses
