The sea is a source of non-intermittent renewable thermal energy. Seawater heat pumps use a thermodynamic system making use of hot or cold seawater to produce energy from the ocean’s depths to provide both heating and cooling networks to the end user within a radius of several kilometres

Suitable for high density coastal areas, this marine energy technology is developing in the Mediterranean area with its high water temperatures, lack of tides and favourable water depths.

OptimaPac is an integrated research project which aims to develop a working industrial sector gathering together players in the Ocean Thermal Energy Conversion (OTEC) value chain. The purpose of the project is the optimization of OTEC technical and environmental performance in its entirety, taking into account the potential effects on the marine environment and conditions for the favourable development of ocean thermal energy conversion.

The project is based on three major complementary actions:

  • Modelling thermal plumes in existing OTEC projects and the dispersion effects in the marine environment and integrating hydrological and oceanographic data.
  • Study of the effect of existing OTEC projects on organisms and marine communities.
  • The development of efficient technological solutions adapted to seawater using the results acquired from the above and integrating range of services for the end user.
