Engineers who utilize seabed turbines to generate electricity through the use of sub-sea mounted systems, along the coastlines of Scotland, are transforming unrelenting tidal currents into dependable sources of clean electricity. Offshore of the Inner Sound of the Pentland Firth, bi-directional tidal currents now generate massive 1.5 MW turbines that symbolize the maturity of tidal energy technology in terms of predictable generation and low-surface-impact. These underwater giants represent a major milestone in the development of ocean-based renewable-energy resources. Turbines capture energy efficiently underwater Tidal current turbines function on the identical principles as wind turbines; however, tidal current turbines are capable of functioning within a far more dense environment seawater. Since water is approximately 850 times denser than air, even moderate tidal velocities can generate considerable torque on turbine blades, allowing for turbines to collect a substantial amount of energy during both ebb and flood tidal phases. The Scottish turbines were developed as part of a specialized tidal power technology suite that utilizes a horizontal-axis rotor, variable-speed pitching, and a nacelle yawing system to maximize energy collection from the constantly changing direction of tidal flow. Installation at seabed depths done safely The turbines used in Scotland are designed for installation at seabed depths ranging between approximately 35 meters and 100 meters using gravity anchors, pins, or piled foundations, depending on the type of seabed encountered. As they will be entirely submerged, there will be neither a visual nor an auditory presence at the surface, and they will not disrupt normal shipping traffic. Furthermore, the modularity of the technology will enable multiple units to be configured in arrays to increase the magnitude of power production as a result of available resources and site-specific factors. MeyGen project leads tidal development In Scotland, the MeyGen project represents the most commercially advanced application of this technology to date. During 2014, tidal energy developers issued a landmark purchase order for three 1.5 MW tidal current turbines to be installed in the Pentland Firth, one of the most energetic tidal environments in the world. The MeyGen project was among the first large-scale commercial orders for tidal current turbines and represented the first phase of what may become a much larger tidal array. Adapting to variable tidal flows Located at this site, the turbines collect kinetic energy from strong tidal flows that are sufficient to exceed the maximum speed capable of producing grid-scale generation. Additionally, the robust design of the turbines, including variable pitch and yaw systems, enables them to adjust to variations in flow velocity and direction, maximizing power production on a per-tidal-cycle basis. The powerful tidal flows located in the Inner Sound, combined with the thoroughness of the engineering and testing process, provide an ideal setting for demonstrating the feasibility of sub-seabed tidal energy production. Predictable energy supports grid stability Upon completion and connection to the grid, the turbines produce predictable renewable energy due to the repetitive nature of tidal cycles, which are generated by gravitational forces among the Earth, moon, and sun. Tidal energy has a unique advantage compared to solar and wind energy, as it can be accurately forecasted for many years in advance, providing an additional layer of support to grid stability, in addition to other forms of renewable energy. Future plans for expansion While the 1.5 MW turbines currently installed are expected to continue producing energy in the future, the long-term plan for the tidal array includes hundreds of turbines producing hundreds of megawatts of power to contribute to Scotlands renewable energy portfolio and promote local energy security. Due to its modular design, seabed installation, and low-surface-disruption, this technology provides a promising option for coastal countries interested in expanding their renewable energy portfolios. As ocean energy technology advances, projects similar to MeyGen show that tides steady and predictable can be converted into a scalable means of powering communities with massive steel structures rooted deep beneath the waves.
