In what is described as a major step towards bringing rigid sails onto powered ships, Eco Marine Power (EMP) has signed a patent license agreement with Teramoto Iron Works Ltd concerning patents related to EMP’s EnergySail and Aquarius MRE technologies.
EMP says that Teramoto Iron Works is one of the few companies in the world that has experience in the production of rigid sails and was involved in the manufacture of JAMDA sails in Japan in the 1980’s. Teramoto Iron Works was selected to manufacture the first production version of EMP’s EnergySail in 2016 and this latest agreement with EMP paves the way to full commercial production once sea trials have been completed.
The patented EnergySail is an automated rigid sail device that enables ships to utilize the power of the wind to reduce fuel consumption and lower vessel emissions. It can also be fitted with flexible marine-grade solar panels or other devices and used to charge batteries or the electrical power fed into a ships power system. Alternatively an EnergySail array can be incorporated into EMP’s Aquarius MRE (Marine Renewable Energy) solution.
