Japan-based Eco Marine Power (EMP) is set to put its EnergySail technology to the test next year. When the system is fully integrated, vessels will draw their power from rigid solar energy sails, simultaneously harnessing the power of the wind and sun. EMP will be working with strategic partners and ship owner Hisafuku Kisen K.K. of Onomichi, Japan.
The EnergySail design can be made from either strength steel or carbon fiber. The structure sits on a ship’s deck on top of a rotating pole. Embedded, rigid solar panels act as sails, storing away energy used to augment the vessel’s power.
When on the high seas, human-made materials are always on unstable terrain. During times where environmental conditions are too harsh to safely utilize the EnergySails, they can be lowered and tucked away until the weather clears. As the ship is docked and waiting to take to the seas, the sails will be gathering solar energy. This power will be syphoned into an onboard battery.
“Our company is pleased to be part of this exciting project which is leading the way towards the use of renewable energy related technologies on ships,” says Mr. Chikashi Yamane, President of Hisafuku Kisen.
A feasibility study is currently in motion, consisting of estimating the power of propulsion the EnergySails can provide on several bulk carriers. The trials will also measure the total amount of solar power each vessel can install.
One ship will be chosen out of the feasibility test group to set sail for an extensive sea trial lasting around 12 to 18 months. This next step is set to take place next year.
