We cannot envision a future in which the dependence on fossil fuels and the emissions of CO2 and other polluting gases are still an issue. That is why we have rolled up our sleeves and have started working on solutions that will drive that dependence out of ship transport and, in the future, of the production of hydrogen and oxygen. For years, we have worked on the design of a rigid wingsail technology applicable to the maritime transport in order to reduce the fuel consumption and the emissions level.  “Maximizing the use of wind for cargo ships”
Also, we are working on an alternative application of the wingsail technology to design in the future a boat propelled by these wingsails, capable of producing hydrogen and oxygen by means of the electrolysis of seawater in a clean and cost-efficient way.  “Being able to produce low-cost, green hydrogen using our wingsail technology”

The maritime transport is in a continuous growing PATH and is facing a double challenge:
i.    The global rise in fuel prices.
ii.    Tighter environmental regulation on pollution issues [not only about CO2 but also about other pollutants: nitrogen oxides (NOx), sulphur oxides (SOx) and particulate matter (PM10)] is entering into force.

Therefore, there is a clear need around new technologies to take advantage of alternative energy to take fossil fuel dependence out of maritime transport.

bound4blue is now working with two main complementary wingsails designs, for heavy and light applications, focusing on bulk carriers and tankers as the main target.

Our technology reduces fuel consumption and pollutant emissions of maritime transport by generating effective thrust from wind power. These wingsails, designed as an engine assist technology, are fully automated and do not require additional crew members for its operation. bound4blue wingsail technology allows merchant vessels to operate at their nominal service speed with reduced engine propulsion. Some of the main key advantages are:

Use of a non-symmetrical airfoil section (improved thrust)

  • Completely foldable to ship’s deck
  • No interference in visibility in harbor and with cargo handling due to folding capabilities
  • No size/height limit (only structural or stability)
  • Minimal interference in cargo capabilities
  • Suitable for automation, no extra crew required
  • Hydraulic/mechanical control
  • Heavy duty materials
  • Safety in extreme weather conditions
  • Payback periods < 4 years for large configurations

Payback periods < 3 years for smaller versions
