" Ocean Power Delivery Ltd is developing a novel offshore wave energy converter called Pelamis. Building on technology developed for the offshore industry, the Pelamis has a similar output to a modern wind turbine. The first full-scale pre-production prototype will be built later this year and tested at the proposed UK Marine Energy Test Centre in Orkney. The company has won a bid for a 750kW project off Islay, Scotland under the Scottish Renewables Obligation and has recently signed a memorandum of understanding with BC Hydro to develop a 2 MW project off the coast of Vancouver Island, Canada. ...

" Formed to develop technology for exploiting flowing water in general and tidal streams in particular. The goal is both to arrive at cost-effective and reliable power systems and to develop these commercially on a large scale. This is being achieved through a phased R&D programme and in partnership with an industrial consortium together with various strategic partners who are shareholders in this company.
Marine Current Turbines Ltd has no intention of manufacturing the technology; this function is achieved by its partners and "third parties", but the company does research the resource with a view to developing future projects. Basically we will develop own and deliver the technology and the resource to go with it. ... " more
"Blue Energy Canada is commercializing the Davis Hydro Turbine, a technological breakthrough able to generate high-density renewable and emission-free electricity from ocean currents and tides at prices competitive with the cheapest conventional sources of energy today. Over an 11-year period Blue Energy has leveraged $300 million of Intellectual Property development into a world-class renewable energy system. Designed by eminent Canadian aeronautic and hydrodynamic engineer Barry V. Davis, the development lineage of the Davis turbine is directly linked to two engineering marvels that preceded its development - the famous Avro Arrow supersonic jet developed by the Canadian government, and the D'Havilland Bras D'Or 400 naval destroyer produced by the Canadian navy. Barry Davis was an aerospace engineer on the Avro Arrow and chief hydrodynamicist on Bras O'Dor Hydrofoil project. ..." more
"Sea Power has developed a wave power station that is environmentally friendly. It is based on established technology from the shipbuilding and hydro-electric power industries. The seawaves are expected to provide a noticeable share of energy supply in the future. The resource is inexhaustible and environmentally friendly. The Internet is used to steer and control wave power production and grant electricity users access to the resource. Sea Power of Scotland Ltd was formed in September 2000. Within the framwork of this entity, which operates out of Inverness, Scotland, Sea Power's UK operations are conducted. At present time, most of this work is centered on negotiations with e.g. local shipbuilding industry and Scottish investors. ..." Products : " The stream turbine concept consists of a turbine house with a Savonius turbine, mounted under a buoy that is anchored so that it can not rotate with the stream. The turbine is independent of the direction of the stream wherefore the turbine, which is connected to an electric generator, can extract the energy in both tidal streams for instance. ..."
" As world leaders of commercial wave powered electrical generation technology, Wavegen has pioneered the research, development and manufacture of several innovative marine power systems. " Established in 1992, by Professor Alan Wells FRS inventor of the Wells Turbine, Wavegen has developed a range of energy modules for clients to exploit the unlimited wave energy resources in the shoreline, near shore and offshore environments. ..." more Technology : " Wavegen's devices are comprised of two basic elements; a collector to capture the wave energy and a turbo generator to transform the wave power into electricity. ..." more
" Ocean Wave Energy Company (OWECO) is pioneering a novel Ocean Wave Energy Converter through an active research program. The technology was conceived while the inventor was an undergraduate architecture student with growing interest in industrial design. As participant in a studio, "Ocean Habitat", having primary design focus on living and research spaces at water's edge, on the ocean hydroface, or in subsurface environs, the inventor made many sketches of rather organic nature including "research spheres" arranged in such configuration to resemble the general shape of octopi. The spherical bodies were to be interconnected by idealized tensile materials, analogous to muscle tissue, that electrochemically contract or expand to raise or lower spheres to particular ocean depths of research interest. While technologically unfeasible in 1978, further exploration disclosed the nature of water waves and, particularly, attenuation of water particle motion correspondent to depth. Neutral buoyancy concepts embellished the design approach. Consideration of relative distance between two spherical buoys, with one floating on hydroface and the other suspended at essentially undisturbed strata, revealed significant change from effective wave motion. ..." more
" Energetech Australia Pty Ltd is a renewable energy company. Energetech’s founder, Dr. Tom Denniss, has developed a new and commercially efficient system for extracting energy from ocean waves and converting it to electricity. The technology now makes it possible for wave energy to provide a cheap, sustainable source of power to grid-connected and remote power users. ..." more
"OpenHydro is a technology business that designs and manufactures marine turbines to generate renewable energy from tidal streams. The company's vision is to deploy farms of tidal turbines under the world's oceans - silently and invisibly generating electricity at no cost to the environment. OpenHydro's technology enables the ocean's immense energy to be harnessed for the benefit of all. The electricity produced is completely renewable since it relies on tides that are created by the gravitational effect of the sun and moon. OpenHydro was formed in 2005 after the negotiation of world rights to the Open-Centre Technology in late 2004. The technology was developed in the USA over an eight year period prior to 2004..." more
" Finavera Renewables is a publicly traded company (TSX-V: FVR) dedicated to the development of renewable energy resources and technologies. Finavera Renewables' objective is to become a major renewable and green energy producer by developing and operating its assets in the wind and wave energy sectors. In addition, Finavera Renewables is positioning itself to become a developer and supplier of renewable energy innovation through the acquisition of interests in key proprietary technologies." more " Finavera’s offshore power plants consist of patented wave energy converters that are based on proven, survivable buoy technology. Clusters of these small, modular devices called AquaBuOYs are moored several kilometers offshore where the wave resource is the greatest. The power plants are scalable from hundreds of kilowatts to hundreds of megawatts. Finavera power plants are designed to provide clean, renewable energy for large population centers. The offshore plants are suitable as distributed generation and load balancing at coastal transmission points." more
