ENEMAR 2015 - Marine Energy Conversion


Oceans represent one of the most promising and emerging renewable energy resource in the world, and Italy, with almost eight thousand kilometers of coastline, is in a position to be one of the leading countries for research, development and deployment of new marine technologies. The actual energy production from marine sources depends on the resource availability (waves and currents mainly) and by the possibility to convert this potential into electrical energy. 

In this context, we have refined the energy potential assessment at regional and local level, focusing on the northern coastal area of the Lazio region, and we proceeded with the in situ measurement activities in the area in front of the port of Civitavecchia. In fact, the breakwaters of the of the Civitavecchia Port was selected by RSE for a future installation and pilot testing of the WaveSAX device, both for scientific issues related to the local wave climate and for logistical reasons, as well. The WaveSAX is an oscillating water column device, developed by RSE, with the aim to generate energy from waves. The authorizations for the installation of the waves measuring system (consisting of barnacle and Mini ADP 1.5 MHz sensor) in front of the breakwaters of the of the Civitavecchia Port have been renewed and two measurement campaigns have been performed; the first in 2015 and the second in 2016. Both the measurement campaigns have been affected by environmental and marine adverse conditions, that have not allowed a systematic data collection for the entire period.

The records obtained from the first measurement campaign were used to calibrate the waves propagation numerical model, from offshore to the shoreline. Following, the model has been applied to simulate the wave climate in the same site where the ADP sensor was installed, for the period from January 2015 to February 2016, and assess the mean annual energy available in this period.
