Background<\/p>\n<\/div>\n\n

Several cooling solutions were considered, but Air2O technology was selected for this project. Air2O made it possible to exceed the PUE requirement and design units that could be installed despite significant space constraints. Air2O was the most efficient cooling technology for large spaces on this project.<\/p>\n<\/div>\n\n

Description<\/h2>\n<\/div><\/div><\/div>
\n\n<\/div><\/div><\/div>
\n

With its ambition to cut carbon emissions by 30% by 2030, collaboration between waste heat producers and consumers represents a real opportunity for the La Rochelle area.<\/p>\n<\/div><\/div><\/div><\/div>

\n\n<\/div><\/div><\/div>
\n

The La Rochelle Energy-from-Waste plant (UVE) is a treatment centre for waste from local authorities and industry.<\/p>\n<\/div><\/div><\/div><\/div>

\n\n<\/div><\/div><\/div>
\n

The facility processes 65,000 tonnes of waste each year, producing electricity and heat.<\/strong><\/p>\n<\/div><\/div><\/div><\/div>

\n\n<\/div><\/div><\/div>
\n

A significant amount of this heat is recovered through the district heating network serving the Mireuil and Port-Neuf neighbourhoods and the nearby Rhodia plant. However, recovery is limited and a large amount of heat is still lost and released into the atmosphere.<\/p>\n<\/div><\/div><\/div><\/div>

\n\n<\/div><\/div><\/div>
\n

Based at Chef de Baie since 1994, the fishing port, located a few kilometres from the plant, lands an average of 2,000 tonnes of fish on its quays each year. This intense activity requires significant cooling to preserve seafood. This cooling is currently produced by energy-intensive installations using refrigerants with a high environmental impact.<\/p>\n<\/div><\/div><\/div><\/div>

\n\n<\/div><\/div><\/div>
\n

With its \u201cMove Heat to Cold\u201d (MH2C) mobile thermal battery technology, Water Horizon will distribute renewable positive-temperature cooling from the plant\u2019s waste heat.<\/p>\n<\/div><\/div><\/div><\/div>

\n\n<\/div><\/div><\/div>
\n

The MH2C battery is charged using heat from the plant; once full, it is transported to the Chef de Baie port to supply cooling. To provide continuity of service to the fishing port, this project will include 2 batteries.<\/p>\n<\/div><\/div><\/div><\/div>
