The granting of financial assistance from Sweden of 139 million SEK (about 15 million euros) to the company Seabased Industry AB for the construction of a demonstration plant capable of producing wave energy has been authorized by the European Commission.

The idea to draw the wave energy is gaining ground in recent years, but has not yet reached the commercial stage. In its decision, the Commission finds that public funds allocated to the project are consistent with the guidelines on State aid for research, development and innovation (R & D & I) of the EU.

“If successful, the project closer to the market a green energy technology is currently immature, without unduly distorting competition. It will contribute to achieving the objectives of the EU’s R & D, climate change and to energy, “said Joaquín Almunia, Vice President of the Commission responsible for competition policy.

The Commission found that the research could not obtain adequate financing on the capital market because of its complexity and importance of its risks. She also thinks it may have significant benefits in the European Union in terms of dissemination of knowledge, environmental protection and energy security.

Then, the project should provide valuable information on the design, operation and sustainability of systems based on technology wave. Despite the many projects underway or planned in this field in Europe and other parts of the world, there is currently no commercial application running continuously at significant power levels.

The total cost of R & D project is estimated at Seabased 344 million SEK (37.5 million), of which SEK 139 million charged to the Swedish government. This project will be implemented in cooperation with the energy company Fortum Oy

The technology uses the Navy Seabased height differential between the crest and trough of the waves. The system is also designed to provide increased power at low speeds.

The wave energy device consists of a permanent magnet generator for direct drive linear, specially developed to capture wave energy by a surface buoy (called “point absorber”).

Converter acting as a generator is connected to the buoy by a rope, which moves linearly (from top to bottom) within a fixed stator. In the converter, powerful magnets (neodymium iron boron), generate a magnetic field that converts the kinetic energy of waves into electrical energy.

Each unit is anchored to a certain depth with a concrete foundation. These foundations are designed and sized in accordance with the load and ground conditions.
