Méthodes de calculs des potentiels et productibles associés aux énergies marines : études de cas en Manche-Atlantique

Abstract

case studies in the Channel -AtlanticABSTRACT. -Faced with the development of Marine Renewable Energy (MRE) in recent years and demand from regional public authorities to evaluate the energy potential of their coastal domains, it was necessary to design an integrated tool for determining, at the scale of a site and then a region, first the gross resource per energy type and then its technical potential followed by its technico-economic potential. In response to this need, Artelia mobilised its experts in maritime and river hydraulics and in energy with the aim of developing a tool dedicated to calculating MRE production capacities. With this operational objective in mind, ARTELIA undertook R&D actions in order to determine the state of the art in calculation methods and in tools already developed and in use in other European countries spearheading this activity, especially the United Kingdom (Atlas of UK Marine Renewable Energy Resources, ABPmer,) and the United States (in particular the work of the EPRI (Electric Power Research Institute)). The tool was then developed and applied successively in the framework of calculating the MRE potential of the coastal domain of the Poitou-Charentes region (client: Poitou-Charentes regional council), then through study assessments performed on the marine current power potential of Lower Normandy (client: DREAL Basse-Normandie) and on the MRE potential of the Aquitaine coast (client: Aquitaine regional council -GIP Littoral Aquitain). The tool allows for the assessment of the resources, technical and techno-economic potentials It has been applied to the following topics: marine current power (offshore and in estuaries and rivers), wave power (offshore, nearshore and coastal) and wind power (offshore and floating turbines). This article provides a brief summary of the various aspects of the tool implemented, illustrated through a few examples drawn from the studies referred to above.Key-words: marine renewable energy, potential, producible powerArticle published by SHF and available at
