Project Summary / Description:

Three policy challenges ‚Äî climate change, clean air, and sustainable energy ‚Äî are driving a global search for sources of affordable, accessible and reliable sources of renewable energy. The Oceana marine turbine relies on a design that draws energy from a large sweep area and can be built in a wide range of sizes to meet nature‚ varied tidal, river, and ocean current resource opportunities. The turbine represents a complete design departure from the atmospheric windmill approach that has proven too costly and fragile to transfer into the marine environment where the density of water is over 800 times that of air and creates severe stresses on its axial design. Oceana‚ turbine makes extensive use of composite materials in its primary structure, is based on a new electric systems architecture, has a turbine comprised of just one moving part, and uses a magnetic bearing system that eliminates contact and friction between its one moving part and the primary turbine structure once the current speed reaches a half knot. Taken together, these advances eliminate the need for the high maintenance costs that plague the windmill approach. Oceana‚ marine turbine design offers utilities, project developers and their customers the benefit of low installation and maintenance costs, low operating costs, and predictable electric generation. Given the research that has already been done, production and installation of large-scale turbines will be straightforward. With resources to showcase full-size turbines, market growth should enable Oceana‚ turbines to make a significant contribution to the clean energy revolution.

Mission Statement:

Oceana was formed with the purpose of leapfrogging directly to the ultimate product architecture for a marine turbine capable of generating affordable electricity from Earth‚ tides and rivers. The International Renewable Energy Agency projects ocean energy companies will have ‚Ç¨53B in annual sales by 2050, a convincing indicator of the demand for ocean-derived energy. We aim to be the leading company in this energy sector, ramping up sharply over the coming decade.

Oceana worked with the U.S. Navy for 9-years to perfect its turbine design, testing model designs before upscaling. A beta version then went through two summers of successful testing in Alaska‚ Nenana River aiming to replace expensive diesel energy in remote villages. During 2017, Oceana adopted new materials technologies from adjacent industries to minimize construction costs. On a per unit energy basis, we project our turbines can be manufactured at costs well below those of others seeking to derive energy from the marine environment. All parts can be molded on site or built in a dedicated manufacturing facility and shipped to installation sites using conventional transport.

Oceana is now seeking a partner to build a full-size demonstration version of its patented technology followed by production versions in a wide range of sizes for river and tidal estuary sites around the world. The turbines will be out of sight and designed to operate fifteen (15) years without maintenance, generating CO2-free electricity on a predictable basis at an amortized cost on par with electricity derived from fossil fuel combustion.
