In Marseille, Optimal Solutions, a subsidiary of the Dalkia group EDF, designed and built Massileo ©, a thalassothermic network that produces heating, air conditioning and hot water from 75% renewable energies.
The network is composed of a tempered water loop that connects the calorie recovery plant on seawater - located on the port of Marseille - to the heat pumps installed in the basement of buildings.
This virtuous system allows buildings to exchange their calories. For example, the heat generated by the air conditioning of offices is recovered to produce domestic hot water and vice versa.
Result: zero energy waste.
Since 2017, Massileo has been supplying the Smartseille eco-district with 58,000 m2 of offices, shops and housing. Tomorrow, the network will serve a much larger area, up to 500,000 m2.
KEY FIGURES:
- 75% renewable energy and recovery
- 80% less CO2
- 21 MW of hot and cold production

Project supported by the EDF group: design / implementation via its subsidiary Optimal Solutions and operation / maintenance via its subsidiary Dalkia.
Project financed with European Union assistance via the ERDF, the European Regional Development Fund, ADEME, the French Environment and Energy Management Agency and the Caisse des Dépôts via the European Investment Program Future Investments.
Sustainable Solutions
- the transfer of energy between complementary buildings: the heat generated by the production of air conditioning for the offices is recovered for the production of domestic hot water of the houses;
- the use of thalassothermy, the thermal energy of the sea: 100% renewable, local, abundant, reliable and compatible with the stakes of the operation; indeed, the temperature of seawater varies little and never reaches negative values;
- a temperate water network between the source and the production plants located in each district where heat pumps allow the production of heating, air conditioning and hot water;
- heating energy delivery substations located in the basements of buildings to meet the specific needs of each subscriber.
