Abstract

The development of human activity is inextricably linked to energy consumption. Population growth and rising living standards lead to a rapid increase in global energy consumption. Satisfying energy needs cannot be fully met by conventional sources of depletion. In the context of this emerging 'energy problem', the exploitation of renewable energy sources and their integration into the energy market by commercial exploitation is becoming more necessary than ever.

     This thesis deals with a new and less widely used renewable energy source in Greece, with significant prospects for exploitation in the near future. This is the energy provided by the sea. The energy potential of marine ripple can have a significant contribution to the production of renewable energy. Although wave power engines have been designed and tested for three decades, they have not reached commercial form, as is the case with technologies utilizing other forms of renewables. Also, none of the technologies being tested have proven to be the dominant technology and therefore there is room for promoting new ideas.

     In the present thesis, therefore, first there is an overview of the theoretical background on energy and specifically on wave energy, the origin and creation of waves, as well as the main advantages and disadvantages of using this energy. Reference is made to the technologies of wave energy exploitation, their historical evolution, as well as the categories in which they are distinguished according to their mode of operation and location. Then, in the third section, the necessary data for the estimation of wave potential in the Greek seas and in particular the islands of the Aegean are described. The analysis of these data reveals some areas outside of the Aegean islands’ ports where high dynamic values ​​are present. In section 5, after comparing the individual advantages and disadvantages of each case, it is concluded to propose an area considered appropriate for the technology installation.

     The purpose of this thesis is to explore the potential of installing surface energy for the construction of wave energy embedded in a wind farm at a port in the Aegean Sea, with the aim of harnessing the energy to supply electricity to the island.

     The study concluded:

• Proposal for installation of offshore Wave Water Pillar construction incorporated on a breakwater.
• Taking into account the wave dynamics of the Aegean islands and other criteria regarding the decline in each of the ports examined, the most appropriate island for installation is Crete and more specifically the port of Platanias.
