Shipping going
zero emission

Blue Technology was founded in 2008, as a think tank by Brian Boserup with the ambitious goals to decarbonize the maritime industry and eliminate its need for ballast water.

MARITIME TRANSPORT

A vital and innovative shipping sector is necessary to achieve the UN 2030 Sustainable Development Goals.

The Liberty ships

Traditionally, a ship is designed to carry a certain amount of containers, cars, passengers or tonnage and compromises on its efficiency and aerodynamics due to a length maximum. Liberty is designed purely for optimal performance, allowing us to go zero emissions.

ship propulsion

Going zero emission requires that the energy used for propulsion is delivered by nature, where it is consumed. Wind, solar and wave energy as available power sources. “Liberty” is powered by wind and solar.

Wind energy has dominated the maritime transport for centuries before the introduction of the combustion engine.

We have developed a stayed wing, which can rotate 360° and is scaled to generate sufficient power to manage the primary propulsion in gentle to strong wind conditions.

Solar energy is the strongest sustainable energy source available.

The photovoltaic technology is in a phase of great progress, but not yet powerful enough to become the main propulsion energy source.

To fully utilize the potential from the tall rig, we need a hull that provides sufficient stability, and this is part of the decision to go for a multihull.

This furthermore eliminates the need for ballast water which accounts for around 30% of the total tonnage moved today.

Liberty has a retractable propeller in each side hull driven by an electric drive.

They are deployed when the wind speed is too low to provide sufficient propulsion power.

The retractable propellers are also submerged and generate energy to charge the battery electrical storage system when wind speeds are sufficient.

The energy harvested from the solar cells and the retractable propellers are stored in batteries.

This solution is chosen for service areas with stable wind conditions, while we consider the opportunity of hydrogen/fuel cells for routes where long periods of engine power are needed.
