  • The sea represents a huge renewable thermal energy storage and heat pumps are a thermodynamic system that can draw their thermal source in seawater potentially powering a network of heat and cold to the end users over several kilometers.
  • OptimaPac aims at optimizing the performances of seawater heat pumps, taking into account the potential effects on the marine communities. The ECOMERS laboratory is in charge of the assessment of these effects, using both an observational and a manipulative approach. The structure and composition of macroalgal communities is studied, together with sensitive species fitness and heat shock proteins (HSP) in bivalves as bio-indicators. Particular attention is given to the potential increase of new phenomenon (invasive species, proliferation of microalgae).(1000 characters max, including spaces)
