Abstract
In this study, a joint evaluation of the wind and wave energy over the Black Sea basin is performed for a 20-year time interval. The importance of such a study is enhanced by the fact that the potential of the wave energy cannot be considered high compared to the large oceans, while the wind conditions over the Black Sea can be considered significant in various areas. The wind fields from the U.S. National Centers for Environmental Prediction were used for wind energy estimation. A high resolution wave hindcast database, as resulted from the simulations performed with the Simulating WAves Nearshore model, is used for a detailed analysis of the wave energy potential in the basin of the Black Sea. The reliability of the wave simulation results was increased by means of some data assimilation methodologies. The variability and complementarity of these renewable energy resources was investigated. The analysis showed that there exist some suitable areas for combined wind-wave exploitation.
Highlights
The attention paid to the exploitation of the renewable energy resources has increased significantly in the past years
For the Black Sea, which is a typical enclosed basin with a complicated orography of the region, the wind fields provided by the U.S National Centers for Environmental Prediction, Climate Forecast System Reanalysis (NCEP-CFSR) are considered to have enough resolution to reflect the variability of the area (Saha et al, 2010, 2014)
Based on the main met-ocean parameters available for the 20-year period 1997–2016, the wave and offshore wind energy will be evaluated
Summary
The attention paid to the exploitation of the renewable energy resources has increased significantly in the past years. Since the hybrid wind-wave projects are at this moment in an early stage, probably the first step to be considered at this point would be to collocate wave energy converters in some places where wind farms are already operating. In this way the existing infrastructure can be used and the wave converters can provide a sheltering effect to the wind farm (Onea and Rusu, 2016). On the other hand, Zanuttigh et al (2016), Cradden et al (2016) and Maisondieu and Healy (2015) are some relevant studies related to hybrid marine energy projects
