DESCRIPTION
With its ambition to reduce its carbon emissions by 30% by 2030, the collaboration between waste heat producers and consumers represents a real opportunity for the La Rochelle region.
The La Rochelle Waste-to-Energy Unit is a treatment center for waste from local authorities and industrialists.
The facility processes 65,000 tons of waste annually, producing electricity and heat.
A significant amount of this heat is recovered through the district heating network in the Mireuil and Port-Neuf districts as well as the nearby Rhodia factory. However, recovery is limited, and a large amount of heat is still lost and released into the atmosphere.
Installed at Chef de Baie since 1994, the fishing port located a few kilometers from the incinerator, unloads an average of 2,000 tons of fish on the quays per year. This intense activity requires a significant need for refrigeration for the preservation of seafood. This cold is currently produced by energy-intensive installations, using refrigerants with a high environmental impact.
With its “Move Heat to Cold” (MH2C) mobile thermal battery technology, Water Horizon will distribute renewable positive cooling from the waste heat of the incinerator.
The MH2C battery is charged from the heat of the incinerator, once the battery is full, it is transported to the Chef de Baie port to distribute the cold. To offer continuity of service to the fishing port, this project will include 2 batteries.
IMPACT
UVE de La Rochelle:
→ Better image
→ Reduced environmental impact
→ Upgrade and continuous innovation to meet changing regulations
Port Chef de Baie:
→ Equipment renewal
→ Lower operating and maintenance costs
→ Reduction of GHG emissions
→ Temperature management (accuracy, stability) to ensure the quality and safety of stored products

TECHNOLOGY
Over the past 7 years, WATER HORIZON has developed a unique skill and technical know-how in the recovery of waste heat and the production of renewable cooling.
In Europe, industrial waste heat represents the equivalent of 100 nuclear reactors.
It is on the basis of this significant observation that Water Horizon has developed its Move Heat To Cold (MH2C) technology: recovering waste heat, storing it, transporting it and distributing it to a distant consumer in the form of renewable cooling.
The MH2C battery recovers and values waste heat between 100°C and 200°C to redistribute it in heat but mainly in cold down to -10°C
Water Horizon takes care of everything! Whether you are a producer of waste heat or a consumer, we take care of finding your peer, sizing the project, financing it and operating it.
