Study 3: Heat recovery from industrial vapours

Heat sources in industry represent a significant potential of 109.5 TWh – equivalent to 36 per cent of industrial fuel consumption in France – which is released as waste heat, of which 52.9 TWh is at temperatures above 100°C.

Half of this market relates to the agri-food and chemicals sectors.

Furthermore, vapours from dryers and fumes from kilns account for 30 per cent and 38 per cent, respectively, of the available emissions.

The study focuses on these two industrial sectors to assess the techniques and constraints involved in heat recovery from industrial vapours, and to identify project opportunities for the coming years.
