The results from the site identification for the benchmark case in the French EEZ (North Sea) are presented. The analysis of geospatial and use-specific data results in two potential sites for the investigated area.

Identification Method
The EEZ of France is scanned by an automated search routine [[1], (Prasasti)] which is divided into a geospatial and a use based module. The systematic search is optimizing the geospatial conditions and subtracting areas with use-specific constraints at the EEZ space. The suitable water depth is a key factor for the operation and construction of a LH-PHES. Areas that are reserved for environmental protection purposes are highlighted. Furthermore, the vicinity to marine energy projects such as offshore wind farms offers synergies for planning, commissioning and operation.
Results
The results of the site identification process in the French EEZ show two main potential sites. Besides the water depth, the environmentally protected areas, the distance to shore and indications on suitable soil conditions, e.g. rock and consolidated clay are further key factors.
