Recovering heat from data centres

IT servers in data centres give off a lot of heat. Rather than losing the heat produced, it is recovered and distributed within an urban network that provides heat to connected buildings. Dalkia, a subsidiary of the EDF Group, has a perfect command of this technology.

The example of Paris Val d’Europe (in French)

Arcelor-Mittal, the world’s leading steel producer, has chosen the ecoimpact offer to recycle the energy recovered from its industrial site in Dunkirk for the benefit of the region.

Waste heat is growing in value

Industrial processes use a huge amount of energy and release a lot of heat, known as waste heat. With ecoimpact, Dalkia is able to recover this energy, which would otherwise go unused.
