Clean Energy Technology

Solid state cooling alternative to vapour compression technologies. Applying an external field (pressure field) under adiabatic conditions leads to temperature increase of the caloric material which correspond to a change of volume. On the contrary, when decreasing adiabatically the external fields, the temperature of the material decreases to lower values compared to the initial one. The barocaloric effect is coupled with other calorific effects manifesting in the same material (multicaloric effect).

Solid state cooling alternative to vapour compression technologies. Applying an external field (magnetic fields) under adiabatic conditions leads to temperature increase of the caloric material which correspond to a change of magnetisation. On the contrary, when decreasing adiabatically the external fields, the temperature of the material decreases to lower values compared to the initial one. It exploits the properties of ferromagnetic materials to absorb or release heat from its surroundings.

Thermal storage system integrating heat transfer components into the storage volume, thus allowing more independence between the equipment energy capacity (i.e. total amount of energy that can be stored) and power (i.e. the amount of energy that could be discharged in a given unit of time).

Heat is stored and released at constant temperature thanks to a change in the phase of a material from the solid state to the liquid state. Such systems would be used for temperatures below 0 °C.

Solid state cooling alternative to vapour compression technologies. Applying an external field (mechanical stress) under adiabatic conditions leads to temperature increase of the caloric material which correspond to a change of pressure. On the contrary, when decreasing adiabatically the external fields, the temperature of the material decreases to lower values compared to the initial one. It exploits the properties of shape-memory alloys to absorb or release heat from its surroundings.

Used to pre-cool the environment recovering both latent and sensible heat. Integrated piece of equipment to be coupled with air conditioners or evaporative coolers. Uses both electrical and thermal energy.

Thermal storage system combining a phase-change material encapsulated into a high thermal capacity medium (e.g. concrete). Today, the coupling of multiple storage media could enhance storage density by a factor of two to three.

Heat is stored and released at constant temperature thanks to a change in the phase of a material from the solid state to the liquid state. Such systems would be used for temperatures between 15 and 70 °C.

Solid state cooling alternative to vapour compression technologies. Applying an external field (electric field) under adiabatic conditions leads to temperature increase of the caloric material which corresponds to a change of polarisation. Conversely, when decreasing adiabatically the external fields, the temperature of the material decreases to lower values compared to the initial one.

Trigeneration systems produce heating, cooling and electricity.

Heat is stored and released at constant temperature thanks to a change in the phase of a material from the liquid state to the gaseous state.

Heat is stored and released at constant temperature thanks to a change in the phase of a material from the solid state to the liquid state. Such systems would be used for a temperature of 0 °C. Water acts as the phase change material.
