Zero Emission Ship Design Concept with Rigid Sails & Solar Power

Pathway to Zero Emission Shipping

The Aquarius Eco Ship is a green shipping concept design and ongoing comprehensive study project focused on optimizing the design of ocean-going ships such as bulk carriers, tankers, RoRo vessels and cruise ships, to harness the power of the wind & sun plus incorporate other emissions reduction and energy efficient technologies and future propulsion systems including hydrogen fuel cells.

The Aquarius Eco Ship study project was started by Eco Marine Power Co. Ltd (EMP) in May 2011 and has attracted world-wide interest. So far it has led to the development of several patented design concepts and the trial and commercialization of a ship-based solar power system: Aquarius Marine Solar Power.

Sail Assisted Shipping with Solar Power 

The centre piece of the Aquarius Eco Ship is Aquarius MRE (Marine Renewable Energy) - an innovative and patented fuel saving and emission reduction system that incorporates a variety of elements including marine-grade solar panels, energy storage modules, computer control systems and an advanced rigid sail design.

Aquarius Eco Ship by Eco Marine Power

Aquarius MRE is a zero emission & wind assisted (or sail assisted propulsion) solution which has been designed to be highly flexible and configurable so that the concept can be applied to most ship sizes and types.

Applications for the system include bulkers, oil tankers, general cargo ships, survey ships, passenger ferries, cruise ships, Ro-Ro ships, car carriers & even unmanned surface vessels.

In addition to Aquarius MRE, a future Aquarius Eco Ship would be fitted with other fuel saving measures such as an advanced electrical propulsion system, low power LED lighting, air lubrication, an optimised hull design and waste heat recovery technologies. Fuel cell technology could also be incorporated into the design.

This combination of technologies could lead to fuel savings of 40% or more when applied to existing ship designs and also dramatically reduce the emission of noxious gases such as Sulphur Oxides (SOx), Nitrogen Oxides (NOx) and particulate matter (PM). In addition the use of renewable energy and energy saving measures would reduce the vessels carbon (CO2) footprint.

An Aquarius Eco Ship could include up to 1 MWp of solar power and enough energy storage modules so that the ship would not need to use auxiliary diesel generators whilst in port. This could also enable the ship to operate emissions free when Aquarius Eco Ship CFD Analysisalongside or an anchor.

Both the Aquarius Eco Ship and Aquarius MRE have been designed to take into account the reality of operating rigid sails on ocean going ships and include a range of software and hardware related safety features. The rigid sails for example, can be lowered and stored when not in use or during extreme weather or emergencies. The automated control system will also lower or position the rigid sails to avoid injury to the crew or damage to the ship or sails.

EnergySail Technology - Wind Power & Solar Power for Ships

The rigid sails used by the Aquarius Eco Ship form part of Eco Marine Power's patented EnergySail technology. This renewable energy sail platform allows for a variety of energy sources to be used and managed via the same system. Solar panels & wind power devices can be mounted on the rigid sails or elsewhere on the ship in a variety of configurations.

Aquarius MRE technology will enable ships of all types and sizes to safely use renewable energy in order to reduce fuel consumption and lower harmful emissions in a cost effective way. The Aquarius Eco Ship is an example of how this system could be integrated into a new ship design although it is also suitable for existing ship designs and could be retro-fitted to vessels already in service.

Low Emission Solar-Hybrid Ferry

Low emission passenger ferries are needed on the world's urban waterways, marine parks and tourist areas. That's why Eco Marine Power is currently working with a number of development partners on the 'Tonbo' - a solar electric hybrid propulsion ferry that will incorporate the latest green and eco-friendly marine technologies.

Solar Hybrid Ferry Tonbo The Tonbo will use a hybrid marine power (HMP) system combined with a solar-electric power system to provide the energy needed for both propulsion and on-board requirements for such things as lighting & cooling etc. It is also being designed to be friendly to the environment and also reduce operational costs for vessel owners by slashing fuels costs.

The Tonbo solar electric ferry will use the latest Lithium battery technology and will be able to charge these batteries by using the innovative solar panel system or array mounted on the roof or by using shore power when alongside. In addition, an on-board low emission generator will provide a back-up means to recharge the batteries as required.

The lightweight, high efficiency marine grade solar panels used by Tonbo can be moved to maximise energy from the sun or be lowered so the vessel can move under low bridges, if high winds are present or when the vessel is not in use. Hybrid Ferry Tonbo

The initial Tonbo design is focused on a 200-250 passenger solar ferry or sightseeing vessel and includes an open deck area at the rear and an observation area at the front. However the design is very flexible and the basic Tonbo concept could be applied to other vessels such as workboats, cruise vessels and even fishing boats。

When cruising at low speeds (around 8 knots or less) the Tonbo will be able to operate in all-electric mode using the on-board batteries. This will allow it to move almost silently across the water - ideal for evening cocktail cruises or sightseeing trips.

On-board Marine Computer System

The solar panel array will be positioned via an innovative control system currently being developed by Eco Marine Power and it's development partner KEI System of Osaka, Japan. A data management and performance monitoring system will also be installed.

environmental_innovation_2011 The vessel itself will be constructed from marine grade aluminium and recycled materials will be used wherever possible.

The Tonbo solar hybrid power ferry project is already attracting worldwide interest and was nominated for the prestigious Environmental Innovation Award at the 2011 Sustainable Shipping Awards in London.

It's another example that highlights how Eco Marine Power is at the forefront of developing sustainable shipping solutions for a greener marine future.

Technologies utilised on the Tonbo Solar Hybrid Ferry will also be applied to other EMP projects such as the Aquarius USV (unmanned surface vessel) and Aquarius Eco Ship.

Hopefully in the not too distant future - eco-friendly, low emission vessels like the Tonbo will be a frequent sight on waterways the world over.

Without doubt, the Tonbo Solar Hybrid Ferry is yet another revolutionary vessel design concept from Eco Marine Power.
