Summary: Researchers have developed procedures and designs to obtain energy from marine currents in areas of great depths optimizing the costs.

Researchers from Universidad Politécnica de Madrid (UPM) have developed procedures and designs to obtain energy from marine currents in areas of great depths optimizing the costs.

The new devices using the energy from marine currents in great depths pose the problem of high cost of manufacturing, installation and maintenance. To tackle this issue, members of the Technological Research Group in Marine Renewable Energy (GITERM) at UPM have developed a method to assess the life-cycle cost of a power generation park based on these devices that can be used in the early design stages. The procedure has been recently published in the Renewable and Sustainable Energy Reviews.

After a wide development of offshore wind power, experts agree that the next step is the use of the energy from marine currents, mainly produced by the tides. Today, Europe and Canada are starting to install the first experimental parks based on devices set on the seabed, called of the first generation.

It is estimated that about 80% of the energy from tides are located in areas of over 40 meters of depth. Therefore it is necessary to use a new design device that can operate in areas where it is expensive to install first generation devices such as large structures held to the seabed. These systems of the second generation have anchors and a series of cables that hold the device to the seabed.
