Aquarius Eco Ship – Pathway to Zero Emissions Shipping

Greg Atkinson. The Maritime Executive. 12th December 2020.

Aquarius Zero Emission Eco ShipDuring the last couple of years shipping has witnessed the implementation of regulations aimed at reducing pollution plus measures are also currently being discussed with the stated intentions of improving the energy efficiency of ships and to reduce CO2 emissions. Large zero emissions vessels are also being considered and for these to become a reality, alternative propulsion systems and new or improved energy saving devices will be required.

The Aquarius Eco Ship is a zero emissions design concept and ongoing comprehensive study project focused on optimizing the design of ocean-going ships such as bulk carriers, tankers, RoRo vessels and cruise ships so that they can harness the power of the wind and sun plus incorporate other technologies that will improve a vessel’s energy efficiency. The project has its origins back in 2010 when a feasibility study was started by Eco Marine Power to investigate how various technologies and systems could be used to reduce fuel consumption and noxious gas emissions.

Aquarius MRE: Zero Emissions Power and Propulsion for Ships

Greg Atkinson. The Naval Architect. November 2020.

Aquarius MRE - zero emissions for shippingWorld shipping, along with other sectors of the global economy, is faced with the challenge of moving towards a zero emissions and decarbonised future. Although neither of these terms are perhaps well defined at the moment, what we do know is that there is increasing pressure on shipping to adopt measures and technologies that will significantly reduce its greenhouse gas (GHG) emissions and carbon intensity.

In Japan, a project led by Eco Marine Power was started in 2010 to investigate and then develop a fully-automated rigid sail and solar power solution for use on ships. This solution is known as Aquarius Marine Renewable Energy (Aquarius MRE).

Rigid Sails and Solar Power for Zero Emission Shipping

Maritime Executive. 31st August 2020.

Rigid Sails and Solar Power for Zero Emission Shipping The shipping industry is currently adapting to a number of major challenges related to reducing greenhouse gas emissions and moving towards decarbonisation. The International Maritime Organization (IMO) has outlined an ambitious greenhouse gas (GHG) reduction strategy and the European Union (EU) has also unveiled its own plan to reduce shipping related GHG emissions. Consequently there is an emerging shift away from heavy fuel oils and the recent grounding of the MV Wakashio is likely to reinforce this trend.

Article: Rigid sails for modern ships – it’s unlikely to be all plain sailing

Published by Eco Marine Power and 15th January, 2019.

Recently there has been a relative surge in interest within the shipping sector regarding the use of sail-assisted or wind-assisted propulsion devices. Examples of these devices or technologies include kites, soft sails, rotor sails and rigid sails – and all of them have been fitted to ships in the past.

Published paper: Considerations regarding the use of rigid sails on modern powered ships

Cogent Engineering. Volume 5, 2018 - Issue 1. November 2018.

The global shipping fleet is vital to world trade with billions of tonnes of cargo being transported annually by merchant vessels. This activity however results in large volumes of carbon emissions and airborne particulate matter being released into the atmosphere due to the burning of fossil fuels for propulsion and on-board power. Recently, there has been an increasing focus on the need to reduce fossil fuel consumption and airborne emissions across the shipping sector. To facilitate this, a range of technologies have been developed or are currently in the development phase. Rigid sails are one of these technologies, yet despite these being installed on a number of ships in the 1980s they have to date been unable to gain widespread acceptance. This paper will briefly discuss the history of sails on ships and then review a broad range of issues regarding their use encompassing previous research studies, journal articles and operational experiences.

Aquarius Eco Ship Project: Japanese Companies Push for Renewable Energy in Vessels

JAPANForward. June 16, 2018.

In April this year the International Maritime Organization (IMO) outlined its vision to reduce greenhouse gas emissions from shipping by at least 50% by 2050. This, along with other policy initiatives such as reducing the sulphur content in marine fuels and emission control areas, is driving technological changes across the shipping sector aimed at reducing airborne emissions.

An obvious way to reduce airborne emissions produced by ships is to reduce the amount of fuel they use both for propulsion and for electrical power. For example, a large bulk carrier uses around 40 metric tons of heavy fuel oil each day. This is the type of ship that carries, for example, iron ore from Australia to Japan, and globally there are hundreds of these types of ships operating today. So, reducing fuel consumption by just 10% on bulk carriers alone would save thousands of metric tons of fuel per year.

Sail-assisted propulsion and solar power for ships

LinkedIn. June 1st 2018.

EnergySail Test StationIn recent years there has been a clear shift towards reducing harmful exhaust emissions from the world’s merchant shipping fleet. From January 2020, the sulphur limit for fuel oil used on ships will be 0.50% m/m (mass by mass). This combined with a growing trend towards more sustainable practices in the shipping industry is encouraging  many ship owners to consider alternative and cleaner sources of propulsion and power on their ships. One obvious source of clean power for ships is the wind and therefore in 2012 a development project was started in Japan to address the limitations of the earlier JAMDA sails, plus bring in new concepts and automation technologies.

Research paper: Analysis of marine solar power trials on Blue Star Delos

Journal of Marine Engineering and Technology. November 2016.

In October 2014 the high speed car and passenger ferry Blue Star Delos was fitted with a marine solar power system. This was done as part of a project to study the use of renewable energy on large ships. In May 2015 while the ship operated in the Aegean Sea, the performance of system was checked and a range of data collected. This paper is focused on the analysis of these data and the evaluation of two days of system trials.

Industry Insight: Hybrid Wind Marine Propulsion Systems, a 200 Year Old Idea

Ship and Bunker - 29th May, 2015.

On May 24, 1819 the SS Savannah made history as the first wind power hybrid steamship to cross the Atlantic. The journey from her namesake city in Georgia, US, to Liverpool, England, took 29 days. While she only used steam power for 90 hours of that time, the potential for hybrid marine power had been shown.

Eco Marine Power: Sustainable shipping technology

Maritime CEO - 23rd May 2013.

Fukuoka: Japan is well known for its green tech prowess. Concept designs from the big companies such as NYK and MOL often look like Hollywood sci-fi creations. Nearly three-year-old Eco Marine Power is one of a number of companies in the country coming up with environmentally novel and creative solutions for ships. The difference with this firm is that one of its founders comes from another nation that prizes a clean environment, Australia.

Green Shipping with Wind & Solar Power

Company Presentation - 21st August 2012.

Around 90% of world trade (by volume) is carried by international shipping and it is an essential part of the modern world economy, however ships are also responsible for the release of a range of noxious gases and carbon dioxide. By using wind and solar power on ships these emissions can be reduced and our dependence on fossil fuels lessened.

Sustainable Shipping & Renewable Energy Technologies

Company Article - 21st June 2012

The world's merchant fleet consists of around 100,000 ships and these are estimated to consume 250 million tonnes of bunker fuel annually. Just one Capesize Bulk Carrier or Bulker can use 40 metric tonnes or fuel or more a day leading to an annual fuel consumption of approximately 10,400 tonnes. This results in the emission of around 32,988 tonnes of CO2 and 959 tonnes of SOx or more. Clearly there is an opportunity to significantly reduce fossil fuel use and noxious gas emissions by using renewable energy on ships.

Dawning of the Age of Aquarius

First Published: Maritime Reporter & Engineering News - November 2011.

In 1819 the SS Savannah was the first steamship to cross the Atlantic Ocean, however most of the distance covered during that historic voyage was due to sail power. The steam engines were fitted to act as a secondary propulsion source and designed to be used only when there wasn’t enough wind present for the sails to move the vessel.
