Imtech Marine will supply green technical infrastructure on board Greenpeace’s Rainbow Warrior III.

The company will provide an energy-efficient electrical propulsion system.

The eco-friendly technology only comes into action when there is not enough wind to sail.

Photovoltaic cells in the 190ft vessel convert sunlight directly into electricity, which is used to drive the engine.

In 2010, the ship will make the first voyage around the world powered by solar energy.
