Oyster modules are designed for deployment around 10m depth, in areas where the average incident wave climate is greater than 15kW/m. Neptune is designed for deployment in deeper water of around 32m depth. Neptune generating system is based on proven wind turbine technology adapted to capture energy from tidal streams.
Deployments of the bioWAVE ocean wave power system at Australia's King Island and the bioSTREAM tidal-current power system at Australia's Flinders Island. Each installation will have a capacity of 250kW and willfeed power into Hydro Tasmania's grid. The power generated should be sufficient to supply about 500 homes.
Ocean treader and Wave treader. Comprises a Sponson at the front, a Spar Buoy in the center and a second Sponson at the aft end. As the wave passes along the device first the forward Sponson lifts and falls, then the Spar Buoy lifts and falls slightly less and finally the aft Sponson lifts and falls.
SeaGen, claims to be the world's first commercial scale tidal stream turbine, has for the first time generated at its maximum capacity of 1.2MW. The company claims this is the highest power so far produced by a tidal stream system anywhere in the world.
Has developed and patented a new concept of wave energy device, which traps and compresses air in successive wave troughs. The compressed air is accumulated in a reservoir and is then used to drive a turbine and thus generate power.
Claims it was the world’s first commercial scale machine to generate electricity into the grid from offshore wave energy and the first to be used in commercial wave farm projects. Uses floating bouys like Chinese lanterns.
This wave-powered generator is unique in that it uses SRI’s Electroactive Polymer Artificial Muscle (EPAM) technology, a rubbery material that can generate electricity by simply being stretched and allowed to return to its original shape.
Direct Energy Conversion Method (DECM), has only one moving part. Floats placed in the sea are used to drive linear generators, resulting in the immediate generation of electricity. No hydraulic equipment or air compression is required. The DECM is the simplest marine renewable energy conversion system that exists.
The US Department of Energy (DOE) announced Verdant Power as one of the 14 projects selected under its competitive solicitation for Advanced Water Power Projects. Verdant Power will design, analyze, develop for manufacture, fabricate and thoroughly test an improved turbine blade design structure to allow for larger, higher-power and more cost-effective tidal power turbines.
Subsidiary of Voith Siemens Hydro Power Generation, a group division of Voith AG with a workforce of around 2,500 employees and sales of over €600m in the past business year ~ Voith Siemens Hydro Power Generation claims it is a world leader in the supply of hydro power equipment.
