Where are the suitable coastlines in Japan for energy extraction from the ocean waves?
Ocean Renewable Energies have been considered to be a promising alternative to fossil fuels, especially in countries with vast exposure to the oceans and seas. Among the ocean renewable energies, waves contain the highest energy density, are predictable, and have the least environmental impacts. Although the wave energy has been less investigated, due to high Levelized Cost of Energy (LCOE) associated with uncertainties in energy production estimations. Nevertheless, development in technology is fast, and the efficiency and suitability of wave energy exploitation depend on the areas where the technology is deployed. Formerly, the suitable sites for wave energy extraction have been selected based only on the amount of available energy. However, recent achievements in wave energy studies show that considering the sustainability of the resources is important in locating suitable sites, and affects the selection of appropriate technology and the efficiency of wave energy extraction. Sustainability can be investigated by both short-term (inter and intra-annual) fluctuations and long-term changes (e.g. decadal). Japan has the eighth largest Exclusive Economic Zone (EEZ) in the world, with special rights regarding the exploration and use of marine resources, including energy production from water and wind. In addition, Japan contains 6,853 islands with 29,751 km of coastline, which enables supplying part of the energy demand from the ocean waves. Hence, in this seminar, I will discuss the potential of wave energy in Japan and its sustainability in both short and long-term, based on long-term simulation of wave characteristics and will introduce novel factors and criteria to locate suitable sites for efficient extraction of wave energy, in line with sustainable development goals.
