Tidal Sails
Power guided by nature
Tidal Sails produces affordable clean energy from slow-moving water using efficient, patented technology, operating silently, in harmony with marine life
the tehnology
BeamReach, a patented technology.
Our BeamReach sail-based technology advantage delivers rated power at speeds as low as 3 knots unlike conventional tidal turbines that deliver only 10–15% of rated output at a cost of 3 to 5 times per MW bigger than our product.
BeamReach is lightweight and cost-efficient, harvesting energy across a wide current area below shipping lanes. It offers low maintenance, marine-life-friendly performance, operating silently with no visual impact.

Sustainability
Breaking limits in clean hydro energy
BeamReach features a robust design that ensures reliable and efficient operation, exposing a much larger capture area than conventional tidal turbines at 3 knots while being fully submerged, direct-drive, and gearbox-free, resulting in minimal maintenance.
BeamReach outperforms turbines by 40x or more in a 3-knot current. A typical 5-knot site experiences 5,000 hours above 3 knots but only 10–20 hours at 5 knots. Our strongest competitors require 5–7 knots just to reach their rated power and generate 10% or less at 3 knots.
Since current availability increases by a factor of 7 for every knot less required, needing 2 knots less means 49 times greater resource availability.
BeamReach is environmentally friendly, invisible beneath shipping lanes, inaudible when submerged, and operates with a minimal ecological footprint and zero emissions.
The conventional tidal energy solutions are often too expensive, heavy, and maintenance-intensive, making device cost the main barrier to commercializing tidal energy as an ecological power source.
Tidal Sails was therefore developed to deliver truly clean energy through patented technology that is substantially more affordable, robust, and lightweight than existing solutions.

Innovation leadership
Patented Design Meets Performance
Rooted in Norway
Tidal Sails AS is a privately held company rooted in Norway — home to one of the world’s cleanest power grids, where hydropower and renewables define energy leadership.
The company holds a proven sail-based technology that combines ocean sailing principles with advanced chain systems to generate low-cost electricity from slow-moving water.
High Power at Low Current Speeds
Delivers full rated power at current speeds as low as 3 knots, while competing technologies are generating only around 10% - 15% of their maximum power.
Lightweight Desig, Low cost, High Efficiency
Sail structures designed to maximize energy capture while reducing drag and structural loads, delivering high output by harvesting energy across a wide cross-section of the current.
Adaptable, Scalable Power Generation
Modular systems ranging from 100 KW to 10 MW are designed for deployment in rivers, straits, tidal channels, and coastal currents, providing scalable energy generation in low-velocity flows.
Submerged, Silent, Marine-Friendly
Designed to safely coexist with marine life, the slow-moving sails are installed up to 15 meters below shipping lanes and operate silently with no visual impact.
a Norwegian company
Tidal Sails AS
Tidal Sails originated from a simple question posed by norwegian founder and CEO Are Børgesen, back in 2003: Could the principles of ocean sailing be used to harvest energy from tidal currents instead of wind?
This idea led to a patented concept and prototype in 2007, followed by years of testing and refinement. More than two decades of innovation have resulted in the sail-based technology alled BeamReach, a mature and proven system combining sailing principles with an advanced chain-based drag system to generate predictable, low-cost, clean electricity from slow-moving water currents.
We deliver turnkey, high-performance hydropower plants and supply clean electricity from our own installations, harnessing slow-moving water currents for long-term energy security.
To advance sustainable hydropower by transforming slow-moving waterways into a resilient source of clean energy, supporting climate goals, strengthening energy independence, and empowering future generations.
Founded
Tidal Sails AS, an independent, privately held company established in Haugesund, Norway, aims to extract kinetic energy from slow-moving water.
Firt tests
Tank and wind tunnel testing, Univ. of Hertfordshire, UK, as part of early development efforts
First prototype
The original idea was patented, and the first prototype was finally deployed in Skjoldastraumen, Norway.
Research and Development grant
Awarded a €3.5 million Eurostars project and recognized as the “Best Norwegian Proposal” within the program.
