Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Facilitates easy transport and rapid assembly of large-scale thermal storage systems in isolated areas without specialized equipment, reducing construction time and costs while ensuring structural integrity and thermal efficiency.

Implementation Method 1

Excess electricity is therefore converted into heat and stored in a material as a temperature increase. This energy is then released by lowering the average temperature of the materials.

Methodology Applied
Scientific EffectThermal energy storage: Thermal Energy Storage

Implementation Method 2

Heat input and recovery are achieved through the forced circulation of a gas (typically air) set in motion by a set of turbomachinery (turbines, compressors), which serves as the heat transfer fluid for heat exchange.

Methodology Applied
Scientific EffectForced convection: Forced Convection

Implementation Method 3

The material is placed in enclosures for thermal insulation from the environment.

Methodology Applied
Scientific EffectThermal insulation: Thermal Insulation

AI summary

A thermal storage enclosure (1), and a corresponding set of construction elements (2, 4, 6, 11, 12, 19, 21) for thermal storage enclosures, comprising a thermally insulated (9) cylindrical outer wall (6) fixed to a base (2) anchored to foundations (8), and closed by a lid (4), suitable for connection via heat transfer gas outlets (3, 5) to a renewable electricity generation storage system. An inner part (7), comprising a liner (21) not connected to the outer wall (6), forms a floating structure made up of several layers of a thermal storage material (10) separated by metal grids (11, 19) supported without fixed connection by interlocking tubular segments (12). All the constituent elements (2, 4, 6, 11, 12, 19, 21) are factory-made and easily transportable as a kit for simplified assembly without specific equipment or manpower.
