This breakthrough will allow tidal energy to become the primary renewable energy contributor by 2025.

Renewable Devices Marine has revolutionised the generation of clean offshore energy with the development of the Capricorn Marine Turbine. This unique tidal stream turbine has allowed Renewable Devices Marine to make available - for the first time, anywhere in the world - a technology which offers reliable tidal electricity generation at a cost lower than offshore wind. The technology can generate electricity from average tidal areas found all around the UK and worldwide, rather than in a select few hard to access, environmentally sensitive, high flow sites. This breakthrough will allow tidal energy to become the primary renewable energy contributor by 2025.

The rush for ‘high tech solutions in the marine energy industry however has led to the development of very expensive and complicated devices. In addition to this, almost all developers have to date sought to extract energy from the highest flow sites available - such as the Pentland Firth. These two factors have led to the development of over-engineered and expensive devices being deployed in the most hazardous and demanding marine environments. All a little unnecessary when the machines themselves can be designed and manufactured with a great deal less inherent complexity and deployed in sites which have lower speed flows and so lower forces on the turbines. This is the cornerstone of the design philosophy for the Capricorn Marine Turbine range - 50 kW and 1.25 MW, twin rotor devices optimised for simple deployment and efficient energy extraction across a range of tidal flows.
The UKs Energy Technology Institute show the existing cost of energy from tidal generation to be approximately £300/MWh. By comparison, offshore wind currently costs approximately £133/MWh, The innovative design of the Capricorn Marine Turbine means that a cost of under £128/MWh is achievable. This is due to the turbines ability to operate invisibly in easily accessible low flow areas that are not environmentally sensitive and are close to the populations that need the energy.

The Capricorn Marine Turbine can generate clean and reliable tidal energy at half the cost of current tidal generation and less expensive than electricity from offshore wind turbines.

The Founders of Renewable Devices Marine Ltd, Dr David Anderson and Dr Charlie Silverton, are ethical industrialists who have dedicated their careers to the local manufacture of innovative renewable energy products. With thousands of their UK-manufactured wind turbines having been exported worldwide, and sustainable hospital units donated to Africa, Renewable Devices has proven that modern day industrialism can provide employment, sustainable development and help the economy, whilst remaining true to firm environmental values.
