This collaborative project between the University of Sherbrooke, CETAB+ and four industrial partners (Hydro-Québec, Aerogéothermik, Emerson, Atis Technologies) aims to evaluate the potential of innovative hydroelectricity-based solutions to replace fossil fuel consumption in Quebec's vegetable greenhouses. Dehumidification and heating technologies using heat pumps and (aerothermal) geothermal energy will be developed, optimized and then implemented at partner greenhouse growers (Ferme des Quatre-Temps, Abri Végétal and Serres Royales).
