The scheme has so far allocated 25MW of the scheme to the Windfloat project, which involves demonstration of floating offshore wind turbines in real operating conditions.
The wind turbines are mounted on a floating platform instead of columns fixed to the seabed, enabling the deployment of turbines in deeper waters.
For the remaining 25MW, entities can file proposals until the end of the year.
The selected entities will receive a 25-year state aid in the form of feed-in tariff (FiT) to compensate for the higher costs of the new technologies.
EU competition commissioner Margrethe Vestager said: "The development of new renewable technologies is crucial to help Europe meet its environmental commitments.
"Today’s approved scheme is an important step for bringing new technologies to the market."
In addition to supporting demonstration projects producing renewable energy from the ocean, the project will help achieve the energy and environmental goals of EU without overly distorting competition in the single market.
