Tidal Currents:
Atlantis Resources- Atlantis’ Nereus™ and Solon™ technologies are both Tidal Current Technologies.  Nereus™ is also suitable for use in rivers, due to its ability to cope with large amounts of debris. Tidal Current technology does not require blocking of any waterways, and hence does not have the adverse environmental effects associated with Tidal Barrages. Atlantis Resources Corporation unveiled the largest and most powerful tidal power turbine ever built, the AK1000™, August 11 at Invergordon, Scotland. Amazing. See the photos!!!
Marine Current Turbines Ltd is in development of new technology for exploiting tidal currents for large-scale power generation. Marine Current Turbines installed the world’s first offshore tidal turbine near Lynmouth off the coast of Devon in May 2003 and completed installation and commissioning of the world’s first commercial scale tidal turbine, the 1.2 MW SeaGen, in Strangford Narrows in Northern Ireland in 2008.
Blue Energy Canada Inc. is a green energy technology company commercializing the Davis Hydro Turbine, capable of converting tidal currents into firm, renewable electricity.
Ocean Renewable Power Company-  tidal, river and deep water ocean current energy. Has successfully tested its proprietary ocean current generation (OCGen™) technology and is developing tidal energy projects in three of America’s most robust tidal energy resources: Western Passage and Cobscook Bay, Maine and Cook Inlet, Alaska. Delaware LLC.
BioPower Systems is commercialising ocean power conversion technologies. Through the application of biomimicry, they have adopted nature’s mechanisms for survival and energy conversion in the marine environment and have applied these in the development of their proprietary bioWAVE™ ocean wave energy system and bioSTREAM™ tidal energy system. Australia.
W a v e g e n- wave energy and wave power. Developed and operate Limpet, the world’s first commercial-scale wave energy device that generates wave energy for the grid.

Ocean Navitas’ technology- the Aegir Dynamo™ functions in a unique fashion by generating electrical current from the motion of the prime mover in one phase via a direct mechanical conversion and the use of a bespoke buoyancy vessel. UK.
Oceanlinx. The patented Denniss-Auld turbine used in the Oceanlinx device is significantly more efficient than the Wells turbine most commonly used in other OWC devices at converting wave energy into electricity. The technology has been successfully constructed and tested with the first full scale Oceanlinx wave plant, installed at Port Kembla in NSW, Australia. Oceanlinx has designed and deployed wave energy systems since 1997.
OceanEnergy's cornerstone product is the OE Buoy. The OE Buoy is a wave power generation platform which is designed for survivability. The result of 7 years of research and development is that the OE Buoy has only a single moving part and has just completed over 2 years of rigorous testing in Atlantic waves. To work in such a hostile environment the platform must be designed to extract energy from the waves efficiently and also survive the worst of ocean storms.
Wave Star Energy in scale 1:10 has now been in operation and grid connected since April 2006 at Nissum Bredning in the North Western corner of Denmark. Since then the company's test machine has logged almost 4.000 operational hours in the first 6 months of daily operation, been through 7 significant storms and is a major step on the way towards commercial wave power.
Wave Dragon- Demonstrator is a floating slack moored wave energy converter with a rated capacity of 4-7MW. The Wave Dragon device allows ocean waves to overtop a ramp which elevates water to a reservoir above sea level. This creates a ‘head’ of water which is subsequently released through a number of turbines and in this way transformed into electricity. Water is returned to the vents in the base of the unit.
Wave Hub Project documents.The project has been collecting wave data since January 2005. South West RDA works for and promotes a modern, stronger and more resilient economy across South West England.

Wave energy developer Orecon, based in the South West of England, is looking for investors or a new owner.
SDE's method consists of using sea wave motion to generate hydraulic pressure, which is then transformed into electricity. The system takes advantage of the wave's speed, height, depth, rise and fall, and the flow beneath the approaching wave, thus producing energy. A full-scale model was operated in Israel and produced 40ekW for almost one year.
Swell Fuel generates electricity from ocean wave oscillation. The device completely unfolds when the waves are large or the tide is high making electricity as the buoy moves up and down. The Lever Operated Pivoting Float was developed by Christopher Olson who has made 56 ocean energy converter prototypes so far.

Passing waves move an air-filled upper casing against a lower fixed cylinder, with up and down movement converted into electricity. Deploying a 250kW demonstrator in 2010 with commercial roll-out to follow by 2011. Based on the Moray Firth, in the Scottish Highlands.
AW-Energy's WaveRoller technology by exploits surge phenomenon, a strong, ubiquitous and consistent natural phenomenon. The back and forth movement of surge moves the plate. The kinetic energy transferred to this plate is collected by a piston pump and energy generation potential is being captured and converted into electricity.
