Marine Renewable Energies in the energy transition
Today, the energy transition implementation requires an active search for solutions.
A major acceleration in the development of Marine Renewable Energy (MRE) is underway, from bottom fixed and floating wind power to the emergence of new competitive MRE technologies.
MRE covers, in the wider sense, all the technologies that enable electricity to be produced from offshore resources such as wind (bottom fixed or floating wind turbines), waves (wave engines), currents (tidal turbines), thermal conversion (OTEC) or solar energy (floating photovoltaics).
The diversity of existing technologies and their different levels of maturity open up a wide range of development possibilities, from simulation, to small-scale and full-scale tests, and now even to the first commercial projects for the offshore wind energy sector.

MRE DEVELOPMENT OBJECTIVES
FLOATGEN, the first offshore wind turbine in France, developed by BW Ideol and installed on the Centrale Nantes offshore test site
IN FRANCE
The Multiannual Energy Programme (PPE) already plans for a 3.75 GW call for tenders for wind power and floating wind power in France between 2019 and 2023 and at least 1 GW/year from 2024. An upward revision of these objectives was recently announced with a volume of 2 GW/year from 2025.
The study "Energy Futures 2050" conducted by RTE and published at the end of 2021, based on the elements of the National Low Carbon Strategy, considers from 22 to 62 GW of offshore wind power in 2050 and from 0 to 3GW of tidal power and other MRE, depending on the scenarios.

IN EUROPE
With the Green Deal, the European Union sets targets to reduce net carbon emissions by at least 55% by 2030 compared to 1990 and to become a carbon neutral continent by 2050.
In this context, the overall target for the share of renewable energy sources in the energy mix is raised to 40% by 2030. The deployment of 79 GW of offshore wind power by 2030 and 300 GW by 2050, compared to 16 GW installed by the end of 2021, is required to achieve these targets, according to Wind Europe.
