Our Approach to Ocean Wave Energy

Atargis is a “fast follower” of other ocean wave technologies. We will succeed where others have failed because of our strong scientific and engineering background and our solid understanding of the modes and causes of others’ failures. Thus, we have focused on developing wave energy converters with

  • Storm survivability
  • High efficiency
  • Low levelized cost of energy (LCOE)

Atargis is the world leader in the design and development of cycloidal wave energy converters. The CycWEC is an adaptation of the Voith-Schneider propeller used worldwide by tugboats. Instead of providing thrust in any direction, the CycWEC matches the incoming wave to convert the waves into electric power.

Atargis Energy’s Cycloidal Wave Energy Converter (CycWEC) uses two-bladed, horizontal axis turbines deployed in deep ocean water (~100 m deep) to generate economical, clean renewable energy.

The Atargis CycWEC is installed on a fixed support and operates fully underwater, invisible from the shore, in deep ocean swells. These swells have tremendous energy--a single meter of wave front can contain 20 to 70 kW, enough to power several homes. Using feedback flow control to synchronize with the incoming wave, the CycWEC can completely terminate the incoming wave, extracting more than 95% of the wave energy.

With a 5 MW base unit, the Atargis CycWEC can be scaled to generate clean energy along tens of thousands of kilometers of coastlines around the world. The best locations for ocean wave energy are generally the west coasts of continents, between 40 and 60 degrees of latitude, though many other locations outside these zones can be made to work, depending on their current cost of electricity.

Most anybody who has seen ocean waves breaking at a beach understands intuitively the amount of energy present in ocean waves. However, harnessing this energy has been an elusive engineering goal so far.
