EnergySail

Japan-based technology company Eco Marine Power (EMP) has started production of an EnergySail in Japan in association with EMP’s strategic partner, Teramoto Iron Works.

The EnergySail is a scalable, automated rigid sail device which enables vessels to leverage on wind power to minimise fuel consumption and subsequently decrease vehicle emissions.

The technology can be supplemented with flexible marine-grade solar panels or other devices and can be used to charge batteries, and the electrical power can be integrated into EMP’s Aquarius MAS + Solar solution.

“The technology can be utilised by a range of vessels, including coastal freighters, large passenger ferries and cruise ships.”

EnergySail is anticipated to be the key element of EMP’s patented Aquarius MRE solution, which is an integrated system of rigid sails, solar panels, energy storage modules, sensors and marine computers that allows vessels to leverage on renewable energy sources such as the wind and sun.

The technology can be utilised by a range of vessels, including coastal freighters, large passenger ferries and cruise ships.

Options are being explored to incorporate design variations of the technology into unmanned surface vessels (USV’s) and marine robotic vessels (MRV’s) as well as offshore marine renewable energy platforms.

The mechanical design and production of the EnergySail is being conducted by Teramoto Iron Works, with EMP finalising on the sensor package of the product and an energy storage solution to be provided by Furukawa Battery.

The production and shore-based testing of the EnergySail is expected to be completed in the second half of this year, which will be followed by an extended evaluation phase, including trials on-board a ship, and consultation with classification organisations.
