On behalf of Ocean Energy Systems (OES) and the US Department of Energy, the PRIMRE (Portal and Repository for Information on Marine Renewable Energy) team held an international workshop to explore the potential for sharing data on marine energy. The workshop was held online, hosted by the three US national laboratories that make up the PRIMRE team [Pacific Northwest National Laboratory (PNNL), National Renewable Energy Laboratory (NREL), and Sandia National Laboratories (SNL)]. The workshop participants were invited to attend based on their knowledge and experience with, or responsibilities for, marine energy databases and portals in their respective nations. The workshop agenda included presentations and discussions focused around the value of data sharing, the barriers to data sharing, and solutions to overcome those barriers (Appendix A). A total of 24 professionals participated in the workshop from 11 countries (Appendix B). Prior to the workshop, the participants were surveyed about the marine energy databases they manage, and the results were presented at the workshop (Appendix C). A recording of the workshop presentations can be found here. The three individual breakout sessions were not recorded, but a record of the written (using Google JamBoards) and oral discussion was made to contribute to this report.
