17:30-19:00 – Sponsored Side Sessions


ORE Supergen Hub /University of Plymouth

North Wing, Aula Maxima 

The Future of ORE Research: The early career researcher (ECR) Perspective

The workshop aims to introduce INORE and the motivation for the collaboration with ORE Supergen and MaREI. Discussion on a range of topics (e.g. future of ORE research, employability and development of ECRs) will be tackled in groups. Drinks and nibbles will be available to create an informal atmosphere.


US Department of Energy, Water Power Technology Office (WPTO)

North Wing Building, Council Room 

The US Department of Energy is hosting a discussion on early adopter markets for marine renewables and invites EWTEC conference attendees to participate in a 90 minute discussion on these markets, on the road to wide-spread development of utility scale MRE. Wave and tidal devices have the potential to provide power to a number of end markets that are characterized by high cost, high value energy needs. In particular, this discussion should interest device and project developers, as well as supply chain participants. Please register at:

19:30 -00:00 – EWTEC Banquet

City Hall, City Hall, Anglesea St, Ballintemple, Cork

Upon arriving at the Cork City Hall, Delegates will be met with music and a drinks reception where they will be given the chance to mingle with fellow Delegates. From there they will be moved into the expansive dining area where they will be served a 4 course meal. ‘Pulses of Tradition’ will provide a live performance of Irish music, song and dance celebrating traditional music in Cork City and will teach Delegates the intricacies of Irish dance.
