Economic Energy Genera.on in Low Current Velocity Water
DEEP GREEN - TIDAL AND OCEAN CURRENT ENERGY Power genera*on from *dal and ocean currents is predictable and reliable compared to other renewable energy sources. Minesto has a unique posi*on in the emerging marine energy industry since its technology is the only one known to operate economically in low current veloci*es, of only 1.2-‐2.5m/s, meaning that the technology unlocks hitherto inaccessible renewable energy resources.
Deep Green resembles an underwater kite, comprised of a wing and a turbine, which is secured to the seabed with a tether and moves with high speed in an 8-shaped path in the tidal or ocean current, reaching a speed 10 times higher than the ocean current speed. The unique principle offers a number of advantages: • High efficiency has the ability to increase the relative flow by a factor of 10. • Small in size and lightweight a 0.5MW plant weighs 7 tonnes • Low-cost offshore operations smaller boats and equipment for installation, service and maintenance. • Availability at sites for offshore operations Deep Green sites are accessible up to 14 hours per day versus in high-velocity currents boats can only operate for a maximum of 3 hours per day.
The unique design and all the above reasons lead to the ultimate advantage of a low cost of energy.
Other tidal technologies are designed for high- speed currents with velocities above 2.4 m/s. These sites contain large amounts of energy, but their geographical areas are limited and due to strong water currents, the sites are difficult to operate in. Due to the ability to operate in lower velocities Deep Green complements other technologies rather than compete with them.
