Marine Energy

The processes of extracting the energy contained in the sea and the oceans using various systems are generally defined as “marine energy”. The methods employed utilise fluid dynamic technologies (which exploit currents, waves or tides) or thermal or salinity gradient technologies. Marine energy is regarded as an important source of renewable energy even if the majority of extraction systems are still at the experimental stage. It is estimated that the theoretical energy potential deriving from the use of marine energy is far superior to the global energy requirement.
