How does it work ?

A novel way of dealing with Heating & Cooling

High-Temperature electric Heat Pump

Whenever the rates of electricity are low – typically during the night or when there is excess of renewable electricity on the grid (comin from wind and/or solar) – our novel electric high-temperature heat pump will produce Heating and Cooling in form of thermal energy and store them separately.

Both heat and cooling can then be used by industrial processes, based on their individual needs.


Heat is transferred from a cold reservoir (where cooling energy is stored) to a hot reservoir (where heat is stored) by compressing a special refrigerant having a very low GWP* ( < 10) thanks to heat exchangers.

The cycle is then completed by cooling the refrigerant via an expansion device. This thermodynamic refrigeration cycle allows the system to reach high efficiencies.

*GWP (from Global Warming Potential (GWP) index was developed to allow comparisons of the global warming impacts of different gases. Specifically, it is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period of time, relative to the emissions of 1 ton of carbon dioxide (CO2). The larger the GWP, the more that a given gas warms the Earth compared to CO2) over that time period.                                GWP is 1 for CO2, and is 2,430 and 3,790 (over 20 years, source Wikipedia) respectively for refrigerants R-32 and R-134a commonly used in fridges and cooling applications
