                   1. Introduction


                      Offshore renewable energy sourc-      difference and chemical properties. These
                   es can be divided into two categories,  properties include waves, tidal range, tid-
                   as  shown in  Figure 1.  The  first is  ma-  al current, salinity and thermal gradients,
                   rine renewable energy, which includes  and  ocean  currents.  The  second  includes
                   sources  originating from seawater  and  renewable sources not originating from
                   is defined as energy captured by tech-   seawater, which can be harnessed in the
                   nologies that use the movement of sea-   ocean space, such as offshore wind and
                   water or take advantage of the thermal   solar energy.
