The dataset on Ocean Energy Test Sites in the EU was created in 2016 by AZTI for the European Marine Observation and Data Network (EMODnet). It is the result of the aggregation and harmonization of data provided by several sources from all across the EU. It is updated every year, and is available for viewing and download on EMODnet - Human Activities web portal (https://emodnet.ec.europa.eu/en/human-activities). The database contains polygons representing Ocean Energy test sites in the following countries: Denmark, France, Ireland, Netherlands, Norway, Portugal, Spain, Sweden, and the United Kingdom. Where available, each polygon has the following attributes: test site code, name, location, country, sea basin, sea, distance to coast (metres), resource type (wave, tidal), starting year, ending year, lease status, site status, capacity (kW), depth (metres), area (square km), grid connection, number of berths, developer, position info (it indicates if the attribute value is original from the source or has been estimated) and the studies conducted for the Environmental Assessment (EIA). In 2022 the status of the test sites has been been updated.

The dataset on Ocean Energy projects in the EU was created in 2014 by AZTI for the European Marine Observation and Data Network (EMODnet). It is the result of the aggregation and harmonization of data provided by several sources from all across the EU. It is updated every year, and is available for viewing and download on EMODnet - Human Activities web portal (https://emodnet.ec.europa.eu/en/human-activities). The database contains points representing Ocean Energy project sites in the following countries: Belgium, Cyprus, Denmark, Finland, France, Greece, Ireland, Israel, Italy, Monaco, Norway, Portugal, Russia, Spain, Sweden, The Netherlands and United Kingdom. Where available, each point has the following attributes: site code (ID_1), project code (ID), name, location, country, sea basin, distance to coast (metres), resource type (wave, tidal, salinity gradient, wave/wind), starting year, ending year, lease status, technology (Based on www.aquaret.com/), device, device scale (Full scale, prototype, etc.), project scale (Commercial, Demonstrator Array, etc.), project status (operational, completed, etc.), project capacity (KW), promoter, position info (it indicates if the attribute value is original from the source or has been estimated or calculated the polygon centroid) and the studies conducted for the environmental assessment (EIA). In 2022, new data has been included and existing data has been updated.
