CoNISMa (National Inter-University Consortium for Marine Sciences) and Università degli Studi della Campania “Luigi Vanvitelli” are pleased to welcome you at the 13th European Wave and Tidal Energy Conference EWTEC2019 which is held at the beautiful city of Napoli, from the 1st to 6th September 2019. This international scientific conference, which has been held every two years in Europe since 1993, for the first time is hosted in Italy. EWTEC2019 is the occasion to meet for researchers and world-class companies in the marine renewable energy sector and involves the participation of about 600 delegates from 35 different countries. Universities, research centers and private companies are going to meet with the interest to innovate and to speed up access to the market of wave and tidal devices. Italy hosts an increasing number of actors involved in the development of this sector: big industrial groups, SMEs, start-ups, and several internationally recognized academic institutions. EWTEC2019 will be an ideal opportunity to meet them all in the pleasant environment of the venue: Centro Congressi della Stazione Marittima di Napoli. You will discover the beautiful city of Napoli, the bay, the landscape, the rich history, the architecture, and the Italian way of living. Finally, I want to thank ENEL GREEN POWER as main sponsor, together with CoNISMa who provided the human resources crucial for the success of such event.
