Advantages


Advantages

SAILWINT's unique combination of advantages make it a truly disruptive innovation

Low-cost

Far-offshore winds are stronger and steadier providing an energy yield upside of 20-30% plus additional 10% upside given no wake loss/wind shadow effects compared to current offshore wind farms. No electricity grid connections provide massive CAPEX savings and the mobile approach reduces O&M OPEX. Levelized cost of energy (LCOE) is 50% lower than floating offshore and 30% lower than fixed-bottom offshore wind.

Clean

SAILWINT's energy source is the wind that blows. Renewable energy from the ocean. Pure clean hydrogen as the output. No stationary impact on coastal environments. SAILWINT ships come and go and can be smartly routed to protect sensitive ecosystems.

Scalable

On the open sea space is practically unlimited. No long siting and permiting limits SAILWINT's scale-up. SAILWINT's mobile approch allows for flexible deployment. 10 fleets of aorund 100 scaled-up SAILWINT ships produce and deliver energy equivalent to 5-6 nuclear plants.

Resilient

Most countries are energy dependent. E.g. the EU needs to import more than 60% of its energy demand. SAILWINT enables us to produce our energy much more locally at the seas close to our economic centers. This eliminates geo-strategic dependencies and conflicts and provides a path to energy sovereignty.

Socially acceptable

SAILWINT ships sail on the ocean, out of sight and out of conflict with fishery, tourism and environmental protection. Individual wind turbines are beautiful. But more and more communities resist to become surrounded by them. Our future energy supply should not solve one problem and create another. True innovation creates meaningful and inclusive change that resonates.
