The Business Idea

Tidal Sails brings to market a ground breaking technology to extract kinetic energy from slow moving water, by combining the ancient principles of ocean sailing with state of the art alpine ropeway technology, to generate low cost electricity.

Tidal Sails resilient and extremely low weight technology platform is adaptable to most locations and is protected by a set of patents worldwide.  The slow-moving sails, (6knots) 15 meter underneath the surface, are considered harmless to fish and sea mammals, and do not interfere with shipping lanes.  The autonomous Self Adjustable & Variable Pitch Sail Control System assures optimal pitch according to current speed and direction. In strong currents with concurrent high sideways loads, excess power is effectively bled off in order not to compromise the structural integrity of the ropeway system – similar to easing out the main sail to prevent overpowering the sailboat in strong winds. Consequently, an efficient Peak Shaving is also achieved!

The Market Potential

*beginning non-commercial revenue from the FTI demo plant installed in middle of this year.

The above numbers are example output from a sophisticated spreadsheet model developed by Tidal Sails to plan its business development, for a balanced scenario of Business models 1 and 2.

Potential end customers are those who desire a reduction in their energy costs and have access to reliable, affordable renewable energy sources with low environmental impacts. Power utilities and local authorities can benefit from a reliable and affordable energy source to improve grid reliability, and also to offer an off- grid supply. This is important not only for utilities, but also rural, island communities in maritime regions and businesses like fish farms, resorts, ferry charging stations, lighthouses.

All potential customers seek:

  • Reliable and sustainable energy supplies
  • Competitive cost of electricity without the need for public subsidy
  • Reduced environmental impacts

With our innovative solution we will be able to offer this at lowest price in the market, without subsidies.

Over the past decade, Tidal Sails and its trusted partners have concluded an extensive portfolio of research, with close to €20m invested, 5 patent families and is now into the 4th generation prototypes. It is the time to take the next steps to bring this promising technology to market. Tidal energy has the potential to play a significant role in the future energy system, whilst contributing to the reduction of carbon emissions and stimulating economic growth in coastal and remote areas.

Market analysis and networking already identifies potential specific locations for uptake across Europe and beyond, and discussions already initiated with end users. While Norway has a limited potential for tidal stream power, and abundant hydro and wind resources, with low-cost sails there could be 5 TWh per year of commercial potential.

The company collaborates with eager technological and industrial partners to ensure qualified modeling, optimal solutions and right material before deploying costly full- scale installations. Tidal Sails has carried out a range of theoretical and numerical studies over the years. These have been validated via several prototypes and test rigs, which has resulted in four major technology generation leaps since the drag based “Classic” was patented in 2003.

Tidal Sails 4th generation, “BeamReach” (norsk seilbegrep: bidevind) installation will be installed perpendicular to the current, well beneath shipping lanes. The sails pull the ropes as they “reach” (sailing term) across the current, “jibe” about the first station, then “reach” back, before “beating” about the opposite station, effectively generating electricity via large direct drive generators in the two stations.

The “BeamReach” yields about the same efficiency per swept area as competitors, but can sweep a much larger area, while generating exceptional low-cost electricity. Advanced modeling by Global Maritime indicates 40 times better “cost to capacity” ratio than competitors in 3knots currents.

As the exploitable tidal resource increase by a low estimate of at least 7 times for each knot less required to reach rated power, this is Tidal Sails single most competitive advantage. Competing technologies typically require 5-7knots before reaching their rated power.

Norwegian Coastal Administration-Exclusive Sponsorship Agreement: The Norwegian Coastal Administration is an agency of the Ministry of Transport and Communication responsible for services related to maritime safety, maritime infrastructure, transport planning and efficiency, and emergency response to acute pollution. In this project the main interest is on development of renewable energies in support of maritime infrastructure and maritime monitoring.
