Marine Renewable Energy (MRE) is a priority for the development of the Pays de la Loire Region, given the presence of large historical contractors, dynamic SMEs, recognized know-how in the marine and industrial sectors related to MRE and the presence of a unique density of recognized education and research centres. The entire value chain is covered regionally, with strong complementarities with Brittany Region. The ecosystem of Pays de la Loire has a positioning on the complete cycle of MRE (design, manufacture, operation, dismantling).
Priorities definition of the WEAMEC’s Roadmap :
Priority 1 :
Strategic development issues for a critical mass of academic and industrial partners of the territory, driven by a national and / or international dynamic.
- Focus of WEAMEC tools.
- Strategic use of National and European tools.
Priority 2 :
Themes to provide activity to academic or industrial partners of the territory by enhancing their skills.
- Opportunistic use of National and European tools.
- Less priority on WEAMEC tools in case of competition with Priority 1 projects.
Research and Innovation Roadmap of WEAMEC :
Priority 1 :
- Reduce LCOE :
- of offshore wind energy, by increasing power and size of wind turbines, and in particular in extreme and complex conditions (hard soils, high amplitude waves, etc.),
- of floating wind turbines (including KITE, autonomous floating system for far offshore, …) and floating substations.
- Advancing wave energy by breaking concepts, and by coupling with other sources of energy, for offshore energy self-sufficiency applications, or supplying sites not connected to the grid.
- Amplify the strong skills of the ecosystem and bring the effort to innovative key cross bricks :
* Amplify the development of some strong skills of the ecosystem :
- Multiphase modeling coupled with parks and structures at sea (resources / aerodynamics / hydrodynamics / mechanics / soil / electric),
- Geotechnical and marine geophysics,
- Materials (composites, concrete, metal): advanced technologies of production and behavior in marine environment. Associated modeling.
- Bio colonization of marine structures (modeling, characterization, sea trials, …),
- Monitoring the evolution of structures at sea, correlated with environmental conditions,
- MRE structures/ship collisions
- Logistics from the port to the sea
- Humanities and Social Sciences for the sharing of uses, co-activities and acceptability of MRE technologies
* To focus on key components with high added value allowing a transfer to the regional industrial stakeholders
- Advanced tools for engineering (machines and farms – design, manufacturing and logistics),
- Mooring systems,
- Dynamic cables and electrical connection,
- Metal structures, composites and concretes (laid, floating, blades, …)
- Energy storage devices and power quality management, H2 coupling
- Characterization of sites (resources and impacts), and monitoring structures at sea,
PrioritY 2 :
Take a lead on less mature MRE technologies, such as:
- Tidal energy,
- Wave energy for grid-connected applications,
By valuing the skills of the WEAMEC ecosystem with national or international leaders.
For each of these priorities, an analysis of the International, French and Regional contexts was conducted to support the choices made.
