Eco Marine Power

The company's technologies use wind, solar and electric power to develop more energy efficient vessels with smaller carbon footprints.

[3][4] In 2016 the company announced it had been granted a patent covering elements of its renewable energy system for ships - Aquarius MRE.

The array of rigid sails are automatically positioned by a computer system to best suit the prevailing weather conditions and can be lowered and stored when not in use or in bad weather.The rigid sails are based on EMP's EnergySail® technology and these renewable energy devices can even be used when a ship is at anchor or in harbour.

A central feature of the concept is the use of EMP's Aquarius MRE system which brings together rigid sails, energy storage, solar power and computer automation technologies.

[7] In January 2011, the company unveiled a detailed design for its new Tonbo HMP ferry, with a 250-person carrying capacity, aimed at the tourist vessel market.

The ship uses lithium batteries that are charged from solar panels on its roof, and also includes an onboard biofuel generator.
