We draw upon the support and network of Future Cleantech Architects to create global awareness and find funding sources for our solution which will be able to deliver massive amounts of green electricity at 3 cents/kWh all over the world.

In order to make your technology understandable, it is important to describe it well in few words. We have asked some of our key innovators for a short interview.

What is the key technology idea of Seawind and why do you believe in its future potential?

The key technology idea of Seawind is to make offshore wind simple and economical, using the water to carry the units, and not expensive vessels, for installation. The key principle of the turbine part is an elastic helicopter rotor – see also picture attached – and not a rigid propeller rotor as in three-bladers. This makes the wind turbine much simpler than three bladers are.

What kind of support would you need to massively scale the technology until 2025?

Currently, financing the next growth stages is a key challenge. We approach the growth stages in the following basic purposes:

Investment of EUR 10 MLN for reaching TRL (Technology Readiness Level) 7 and moulds for the blades of prototype Seawind 6
Investment of EUR 25 MLN to install and operate the prototype of Seawind 6
Investment of EUR 15 MLN to reach TRL 7 for Seawind 12, comprising the moulds of the blades
Finally, investment of EUR 35 MLN for installing and operating the prototype of the Seawind 12

What is the main advantage compared to conventional, three-blade systems and how does this translate into a cost benefit?

Our approach allows for a strong reduction of CAPEX (capital expenditures) and OPEX (operating expenditures) in building and running the offshore turbine system. This has to do with less parts (no blade pitch mechanism, significantly less yaw drives) and significantly lower fatigue values (due to the action of the teetering hinge) on rotor blades, hub and drivetrain. Through this, we can extend the lifetime due to lower fatigue values (estimated lifetimes 30+ years).

The cost benefit of all these aspects leads to a strong reduction in cost per kWh of green energy.
