Considering the rapid development of maritime logistics, the reduction of energy consumption at ports is important in the sustainable development of global economics. Oceans have been known as sources of clean energy, and wave energy is attracting more and more attention from both scholars and practitioners. Even though much effort has been made to develop advanced technologies of wave energy, it is still not clear how ports and electricity plants will evaluate its performance and make decisions on the investment. This paper analyzed the decision framework of ports and electricity plants that can decide how much to invest into wave energy converters, by considering the uncertainty of wave energy supply. A mathematical model is developed to obtain the optimal decisions of a single port and electricity plant for different cases. We show that in most cases, the port has a no lower motivation for investing in the wave energy than the electricity plant. Our theoretical analyses also shed light on the impacts of the parameters on the optimal decisions. Considering the difficulty in estimating the uncertainty of wave energy supply, we extend the distribution-free model to our problem which can make our model more practical.

Ocean wave energy conversion as one of the renewable clean energy sources is attracting the research interests of many people. This review introduces different types of power take-off technology of wave energy converters. The main focus is the linear direct drive power take-off devices as they have the advantages for ocean wave energy conversion. The designs and optimizations of power take-off systems of ocean wave energy converters have been studied from reviewing the recently published literature. Also, the simple hydrodynamics of wave energy converters have been reviewed for design optimization of the wave energy converters at specific wave sites. The novel mechanical designs of the power take-off systems have been compared and investigated in order to increase the energy harvesting efficiency.

Energy Converters

In a context of growing global awareness of environmental sustainability, given the risks associated with global warming and climate change, the transition from environmental models to highly intensive fossil fuel production towards new clean energy systems marks the future of global public agendas. In this scenario, a feasibility study of the installation of wave energy converters, such as the Sea Slot-Cone Generator (SSG) and the Oscillating Water Column (OWC), was carried out in existing breakwaters in the North of Spain, choosing Punta Langosteira (Outer Port of A Coruña), Dique Torres and Dique Norte (Port el Musel, Gijón) and Punta Lucero (Port of Bilbao). It was aimed at capturing the great energy potential of the Atlantic Ocean, as an innovative solution linked to the development of renewable energy sources of marine origin. The selection of the most optimal and efficient alternative will depend on different aspects: the quantitative availability of the wave energy resource at the study points, the production of energy obtained by the device and the capacity factor, the capacity of the wave energy facility to supply the energy consumption in every port to boost the image of “Green Port”, the constructive viability so that the condition of having the construction works only during one year and an economic estimation of each alternative.

The Sustainable Development

The communal feature of the utilization of renewable energy sources, spread of technological innovations, and support of energy efficiency is that they all contribute to the sustainable development, the prosperous direction energy supply and through these to the creation of new workplaces. Hopefully in the future this will lead to economic growth, better competitiveness of the country, and the outset of rural planning. In the national respect from the renewable resources the exploitation of biomass, geothermal energy, wind, and solar energy can be guaranteed through the energy supply. As such, a suitable and extensive legal framework is needed, to ensure and track safe and clean energy. This study examines the important economic and environmental connection of the green economy.

Remote Islands

The energy needs of most Aegean islands are covered by the operation of autonomous/local power stations (APS/LPS) using imported oil. The costly operation of the APS/LPS combined with the resulting environmental problems, set the issue of a sustainable and rational energy solution mainly for the remote islands, showing respect to the sensitive island ecosystems and the acceptance of local communities. In this context, high wind speeds as well as the remarkable wave potential of the Aegean Archipelagos could be the driving force for a sustainable energy supply solution for these islands by exploiting combined energy sources along with an appropriate energy storage system, comprising a modern hybrid renewable based station. Moreover, the exploitation of wave energy is one of the future priorities of the European Union (Blue Growth) in an effort to support the installation of wave energy converters, which are in the final stage of technological development. The proposed analysis examines the combined exploitation of the wave and wind potential for a representative medium sized island of the Aegean Archipelagos in order to cover its electrical needs. The results show that the installation of a hybrid power station contributes to a higher integration of renewable energy systems (RES) into an autonomous micro-grid and that the stochastic production of wind turbines can be counterbalanced due to the smoother (time-dependent) production of wave systems. In addition, the ability to store excess renewable energy enhances the energy supply security of an island micro-grid providing a clean energy solution for the remote Aegean island communities and thus reducing their oil dependence.
