Marine Tidal Stream Power Systems
Tidal energy is power produced from the rise and fall of ocean or sea tides. There are several locations on the Earth with regular high tides and high-speed flood and ebb currents that can be used to harvest the energy of large volumes of water moving four times each day without any pollution emissions.
Specially built tidal energy convertors (TECs) or hydro turbine generators can be placed in areas with significant difference between high and low marine tides which results in movement of big mass of sea water. The captured kinetic energy of moving water then can be converted into electricity.
Marine tidal energy is a mostly untapped source of power generation that has several important advantages over the sun or wind power, because it is:
- ● regular, reliable, predictable
- ● not affected by time of the day
- ● not affected by weather conditions
- ● not affected by seasons
- ● not affected by climate change, and
- ● not affecting the environment and safe for any form of marine life.
Unfortunately, marine conditions are extremely harsh for power generation equipment and any underwater structures, and implementation of tidal marine stream power generation systems requires high initial investment; high repair, service, and maintenance costs; and high cost of removal and utilization of tidal power generating systems at the end of their lifecycle.
The tidal stream power generation industry is still in development, with only a few commercially viable implementations around the world.
Unidirectional rotation rotor (UDRR) for hydro power turbines was developed specifically for tidal marine stream generation systems. These systems allow harvesting the energy of marine flood or ebb currents which change 180 degrees four times every day.
Those turbines can be placed on seabed using underwater supporting structures or installed on floating platforms anchored close to the shore and generate electricity in low to medium speed marine tidal streams, both laminar and turbulent.
Our marine tidal stream power generation systems offer following benefits:
- ● Simple yet innovative design with minimum rotating parts.
- ● Absence of additional control systems like yaw and blade pitch control systems normally used in other tidal power generators. It results in higher reliability of our systems.
- ● Low production cost due to using modern manufacturing technologies and plastic materials for turbine production.
- ● Safe for the marine environment and any form of sea life, including any size of fish and sea mammals.
- ● Lower supporting structure construction and installation costs.
- ● Overall lower initial investment is required.
- ● Low cut-in speed, high torque in low-velocity tidal areas.
- ● Reliable, easy to repair and service system.
- ● Lower repair and maintenance costs.
- ● No antifouling coating is needed for turbine blades.
- ● Easy and less costly to remove and recycle in the end of service life.
