“…For the cut-off distribution the percentage located below these values (3 m/s in this case) was evaluated, during which the turbine would not generate electricity. For the rated capacity, the interval between the rated wind speed (12.5 m/s in this case) and the cut-off value was considered, which for most important offshore wind turbines are set to 25 m/s [76]. During this period, the wind generator will report the best performances in terms of electricity output.…”

Abstract:The objective of the present work is to assess the global wind and wave resources in the vicinity of some developing countries by evaluating 16-year of data (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016), coming from the European Centre for Medium range Weather Forecast (ECMWF). Until now, not much work has been done to evaluate and use the renewable energy sources from these marine environments. This is because most of the attention was focused on more promising areas, such as the European coasts, which are more advanced in terms of technical and economical aspects. A general perspective of the current energy market from the selected target areas is first presented, indicating at the same time the progresses that have been reported in the field of the renewable energy. Besides the spatial and seasonal variations of the marine resources considered, the results also indicate the energy potential of these coastal environments as well as the performances of some offshore wind turbines, which may operate in these regions.

“…2. Since most of the turbines operate at a hub height of at least 80 m, the initial ERA-Interim wind conditions were adjusted to this reference level throughout a logarithmic law [18][19][20]. For this work, the time interval located between 1.01.1998 and 31.12.2017 will be considered for evaluation.…”

The objective of the present work is to estimate the benefits which may be obtained from the implementation of a solar and wind project, by considering several reference sites, located in the southeastern part of Romania. In the first case study, the attractiveness of the solar energy will be evaluated for a production factory located in the vicinity of Galati city. The seasonal and annual fluctuation of solar energy will be discussed, by taking also into account the performances of a photovoltaic panel, which may be installed on the roof of these production halls. As for the second case study, the performances of some state-of-the-art wind turbines will be evaluated by taking into account three sites located along the Romanian shoreline, namely Sf. Gheorghe, Navodari and Vama Veche, respectively. According to these results, it was noticed that the photovoltaic panels will partially cover the energy demand for the selected factory, while in the case of wind energy, a single wind turbine defined by a rated capacity of 3 MW seems to easily cover the local electricity budget, reported in Sf. Gheorghe and Vama Veche.

“…Among the different developed marine renewable technologies, marine wind energy is the most mature type as regards technological development, commercialization, policy frameworks, and installed capacity (Soukissian et al, 2017;Agora Energiewende and Sandbag, 2018). Actually, most of the interest is focused on the development of new offshore solutions, such as wind turbines with larger rotors, deep water sites and floating platform (e.g., Hywind Scotland project www.statoil.com) (Onea et al, 2017). Floating technology can be considered in fact, as a commercially viable solution in order to harness available wind resource also at greater depth (>50 m) where the conventional fixed offshore wind turbines are no more economically feasible (McMillan and Ault, 2010).…”

“…The feasibility of combining a floating wind turbine and a wave energy converters has been already investigated by several authors (Fusco et al, 2010;Iglesias, 2013, 2015;Veigas et al, 2014a,b;Gao et al, 2016;Karimirad and Koushan, 2016). wind-wave technology is a viable solution to reduce the intermittence of the wind and wave resources regardless of the time interval, increasing in this way the attractiveness of a site in terms of its overall marine energy potential (Fusco et al, 2010;Azzellino et al, 2013a;Perez-Collazo et al, 2013;Onea et al, 2017). Therefore, the diversification of the mixed renewable energy technologies, determines a reduction of the power's variability (Fusco et al, 2010;Stoutenburg et al, 2010) and the energy costs Iglesias, 2016, 2017;.…”

Combined Exploitation of Offshore Wind and Wave Energy in the Italian Seas: A Spatial Planning Approach

et al. 2019

View full text Add to dashboard Cite

The opportunity to co-locate wind and wave energy exploitation is analyzed in the Italian seas grounding on the rationale that benefits are greater when un-correlated resources are combined. The study shows that, although waves and winds are generally strongly correlated, in some conditions their correlation is lower and the combined energy harvesting more interesting. As spatial conflicts of sea use and demand for maritime space are increasing, the development of the marine renewable energy sector needs to be evaluated in the perspective of the cumulative pressures deriving from present activities or expected from future developments. The evaluation of areas of potential conflicts among human activities, environmental vulnerabilities and marine renewable developments may facilitate the early development of mitigation actions and negotiations between stakeholders. In this study the opportunity of co-locating offshore wind turbines and wave energy converters is analyzed through a spatial planning approach. Both the potential for combining different renewable technologies, and the impact associated to such development was considered in the context of the existing pressures (e.g., naval traffic; mariculture activities; submarine cables routes; dredge spoils dumping; offshore activities; windfarms and ocean energy projects) and vulnerabilities (Marine Protected Areas, Key habitat presence) through quantitative indicators. The portion of Tyrrhenian coast south of Elba island, the northern-western Sardinian coast, and the southern Adriatic and Ionian coastal waters appear to be the most suitable sites. Moreover, the study presents a spatial quantitative methodology to identify sites of potential interest for the development of the marine renewable energy sector in the perspective of cost-effectiveness and environmental impact minimization.
