Assessing the wave energy resource using remote sensed data
Pontes, M.T.; Bruck, M.; Lehner, S.The use of accurate remote sensed wave data in the coastal area (water depth up to 80m) will enable a high quality characterization of the wave energy resource. Work has been carried out with this objective for a number of years namely assessing the quality of the radar altimeter and SAR sensors data. In this paper a summary of the quality of wave period estimates from the NASA/CNES Jason radar altimeter is pre...
Wave energy resource in the North Sea
Beels, C.; Henriques, J.C.C.; De Rouck, J.; Pontes, M.T.; De Backer, G.; Verhaeghe, H.Due to the high potential of wave energy and the goal to raise the share of renewable energy supply in the EU up till 20 % in 2020, the development of wave energy is accelerated. Until now the wave energy resource was highlighted in regions with a high wave energy density. As Wave Energy Converters (WECs) still contend with problems such as structural strength and mooring in a severe and energetic wave climate,...
Spectral Bandwidth and WEC Performance Assessment
Saulnier, J.-B.; Ricci, P.; Pontes, M.T.; Falcão, A.F. de O.This paper investigates the dependency of wave energy conversion on the spectral bandwidth of sea-states. To this aim, the performance of an axisymmetrical Wave Energy Converter is assessed in the frequency domain by using a stochastic model in two far different wave climates (Portugal and North Sea) both represented by more than 23000 energy spectral densities obtained from measurements. The correlation betwee...
Integrating Offshore Wind and Wave Resource Assessment
Pontes, M.T.; Sempreviva, A.M.; Barthelmie, R.; Giebel, G.; Costa, P.; Sood, A.The aim of this paper is to review the sources of wind and wave information, the methodologies to assess offshore wind and wave energy resources, and the more relevant results at the European level as a first step to integration of the evaluation of both resources. In situ and remote sensed wind and wave data (using satellite based sensors) are done generally by distinct systems (except for SAR) but numerical a...
