Emission Abatement Systems – AES to reduce Tugboat Emissions

Emission Abatement Systems for Tugboats: Systems for Cleaner Maritime Operations and Reduction of Tugboat Emissions


Tugboat emissions have become a growing concern as the maritime industry faces increasing pressure to reduce its environmental impact and meet global sustainability targets

The maritime industry plays a pivotal role in global trade and logistics, but it is also a significant source of environmental pollution. Tugboats, essential for maneuvering larger vessels in harbors and confined waterways, contribute to this pollution with their emissions of nitrogen oxides (NOx), sulfur oxides (SOx), particulate matter (PM), and carbon dioxide (CO2). As the world becomes more environmentally conscious, there is a growing emphasis on cleaner maritime operations. 

In the pursuit for cleaner maritime operations, tugboat companies are increasingly focusing on Emission Abatement Systems (EAS). These systems, essential for reducing pollutants emitted by tugboats, mark a significant advancement in environmental stewardship within the maritime industry. As the sector faces heightened scrutiny over its environmental impact, adopting EAS not only aligns with global sustainability goals but also ensures compliance with stringent environmental regulations set by international bodies.

Understanding Emission Abatement Systems – EAS

Emission Abatement Systems are designed to minimize the release of harmful pollutants from marine vessels. These systems target emissions such as NOx, SOx, PM, and CO2, which contribute to both human health and the environment. By implementing EAS, the maritime industry can significantly reduce its pollution footprint and contribute to global efforts to combat climate change.

EAS employs various methods to reduce emissions, primarily focusing on exhaust gas treatment and improved combustion processes. Exhaust gas treatment involves technologies like Selective Catalytic Reduction (SCR) and scrubbers to remove or neutralize pollutants before they are released into the atmosphere. Improved combustion, on the other hand, enhances engine design and fuel quality to achieve more complete combustion and reduce the production of harmful emissions. Techniques such as Exhaust Gas Recirculation (EGR) help achieve this by lowering combustion temperatures and reducing NOx formation.

Selective Catalytic Reduction (SCR)

SCR systems are highly effective in reducing NOx emissions, which are a major contributor to air pollution and have significant environmental and health impacts. SCR technology operates by injecting a urea-based reagent, often referred to as AdBlue or DEF (Diesel Exhaust Fluid), into the exhaust stream. This reagent undergoes a chemical reaction with NOx gases in the presence of a catalyst, converting them into harmless nitrogen and water vapor.

The process involves a series of steps: as the exhaust gases pass through the SCR system, the urea-based solution is injected and thermally decomposes into ammonia. The ammonia then reacts with the NOx over a catalyst, typically made of materials like vanadium, tungsten, or zeolites, to produce nitrogen and water. This method is not only efficient but also reliable, making it a preferred choice for marine applications. The effectiveness of SCR systems in reducing NOx emissions by up to 90% has made them a staple in modern emission control strategies. SCR systems are integral to meeting stringent IMO Tier III regulations, which mandate significant reductions in NOx emissions for ships operating in Emission Control Areas.

Exhaust Gas Recirculation (ERG)

EGR systems recirculate a portion of the engine’s exhaust gases back into the combustion chamber. This technique reduces the oxygen concentration and lowers the peak combustion temperature, which significantly reduces the formation of NOx. NOx is primarily formed at high combustion temperatures, so by lowering these temperatures, EGR systems can effectively cut NOx emissions.

The EGR process involves routing a portion of the exhaust gas back into the engine’s intake manifold. This recirculated exhaust gas is mixed with fresh air before entering the combustion chamber. The presence of inert gases (such as CO2 and H2O) in the recirculated exhaust gases absorbs heat during combustion, which helps lower the overall combustion temperature and thus reduces NOx formation. This method is particularly effective in marine engines, where steady operating conditions allow for optimal EGR performance.

EGR systems also have the advantage of being relatively straightforward to modify into existing engine designs. Their proven efficacy in emissions reduction and their adaptability to various engine types make EGR a viable solution for meeting regulatory requirements. EGR is a well-established technology that continues to evolve, with advancements aimed at improving its efficiency and minimizing potential drawbacks such as increased particulate emissions and engine wear.

Scrubbers

Scrubbers are another effective technology for reducing emissions from marine vessels. They operate by washing the exhaust gases with a liquid, typically seawater or a specialized scrubbing solution, which absorbs and neutralizes pollutants such as SOx and PM. This method is particularly useful for vessels that use high-sulfur fuels, as it allows them to comply with sulfur emission regulations without needing to switch to more expensive low-sulfur fuels.

There are two main types of scrubbers: open-loop and closed-loop. Open-loop scrubbers use seawater directly to wash the exhaust gases, relying on the natural alkalinity of seawater to neutralize the sulfur oxides. The cleaned exhaust gases are then released into the atmosphere, and the wash water is discharged back into the sea after treatment to remove harmful components. Closed-loop scrubbers, on the other hand, use a recirculating scrubbing liquid, usually containing an alkaline substance like sodium hydroxide, to treat the exhaust gases. However, open-loop scrubbers have faced criticism due to their potential impact on marine environments, as the discharge from these systems can harm aquatic ecosystems. This concern has led to stricter regulations in some regions.

Scrubbers can reduce SOx emissions by up to 98%, allowing ships to meet IMO regulations that limit sulfur content in marine fuel to 0.5% globally and 0.1% in designated ECAs. This technology not only helps in regulatory compliance but also offers a cost-effective solution for operators, as it allows the continued use of high-sulfur fuels while still meeting tugboat emission standards.

Benefits of Emission Abatement Systems for Tugboat Operations

Implementing EAS ensures that tugboats comply with international regulations such as those set by the IMO, designed to minimize marine pollution and protect the environment. By adhering to these standards, operators not only avoid penalties but also contribute to global environmental protection efforts.

Beyond regulatory compliance, EAS significantly reduces the carbon footprint of tugboat operations by lowering tugboat emissions of CO2 and other pollutants. This leads to improved air quality in port areas and coastal regions, benefiting both the environment and public health. Cleaner operations also enhance the industry’s image and demonstrate a commitment to sustainability.

Moreover, EAS enhances the operational efficiency of tugboats. Improved engine performance and increased fuel efficiency translate into substantial cost savings over time. By optimizing fuel consumption and reducing maintenance needs, operators can achieve significant economic benefits while maintaining compliance with environmental standards.

Hybrid Tugboat: Pioneering the Future of Maritime Sustainability


An overview of the recent developments for green hybrid tugs

Hybrid propulsion tugboats are at the forefront of transforming the maritime industry. By integrating alternative fuels and cutting-edge propulsion technologies, these tugboats offer significant environmental and operational benefits.

The Paris Agreement of 2016 has intensified global efforts to reduce GHG emissions, making it a critical issue for the shipping sector. In response, the International Maritime Organization set ambitious goals in 2018 to halve GHG emissions from international shipping by 2050, with the ultimate goal of achieving zero emissions by the end of the century.

Therefore, hybrid propulsion comes into play because of its promise of reducing emissions. Hybrid vessels can operate on electrical power combined with conventional fuel or utilize a blend of traditional and alternative sustainable fuels. Tugboats, given their near-shore operations and regular recharging needs, were among the earliest maritime vessels to adopt battery technology. The first hybrid tugboats began operations as early as 2009, with fully electric, zero-emission models following in 2019.

This article explores the innovations in the field of hybrid green tugs, focusing on both the environmental and operational benefits, as well as the challenges. To do so, industry examples and case studies will be provided.

Hybrid Tugboat models through the years

Through the years, tugboats have increasingly relied on batteries and various fuels to reduce emissions and enhance efficiency.

In 2010, the US-based company Foss Maritime’s hybrid tugboat Carolyn Dorothy, powered by diesel engines and batteries, demonstrated significant environmental benefits. It retained the power and maneuverability of conventional tugs while dramatically reducing emissions, noise, and fuel consumption. The hybrid electric tugboat achieved a 73% reduction in particulate matter, 51% in nitrogen oxide, and 27% in carbon dioxide. 

In 2015, NYK Line and IHI Power Systems Corporation developed Sakigake, the first Japanese LNG-fueled tugboat. Using LNG, Sakigake reduced sulfur oxide emissions by nearly 100%, nitrogen oxide by 80%, and carbon dioxide by 30% compared to heavy oil. Currently, IHI Corporation is working on developing a hybrid ammonia-powered tugboat. Ammonia, which emits no CO₂ when burned, shows promise as a next-generation fuel for reducing shipping’s environmental impact. 

Another example of the industry’s commitment to innovation and sustainability is offered by Seabulk’s hybrid diesel-electric tugs Spartan and Titan. These new green hybrid tugs, which started to operate in the USA in 2022, combine the benefits of diesel and electric propulsion for enhanced efficiency and reduced emissions. They offer exceptional power and maneuverability, fitting the high-powered needs of their customers while improving fuel efficiency.

Another example is the Hydrotug 1, operating in Antwerp since 2024, which features dual-fuel BeHydro engines that run on hydrogen or traditional fuel. This tug is part of the Port of Antwerp-Bruges’ plan to transition to a climate-neutral port by 2050.

The Panama Canal Authority’s new hybrid tugboats are another example of the growing adoption of this technology in high-profile operations. In October 2023, the Authority contracted for ten hybrid electric tractor tugboats, aiming to reduce emissions during ship towage through the canal and docking in Panamanian ports. Corvus Energy plays a crucial role in the performance of these 30-meter long hybrid tugboats by supplying advanced battery systems. These battery systems enable the tugboats to operate efficiently and sustainably. Corvus Energy CEO, Fredrik Witte affirmed that the battery systems significantly decrease vessel emissions, supporting the Authority’s goal of achieving net-zero GHG emissions by 2050.

Finally, one last notable project that has yet to come to fruition is Svitzer’s methanol hybrid fuel cell tug. The company is designing the world’s first methanol hybrid fuel cell tug, aiming to combine the environmental benefits of methanol with the efficiency of fuel cells. This new hybrid electric tugboat is expected to enter operations in 2025, helping the port of Gothenburg to fulfil the ambitious target to reduce shipping emissions within the port area by 70% by 2030.

Comparing Conventional and Hybrid Propulsion Systems in Maritime Applications

Insights:

The graphic illustrates a comparison between conventional propulsion systems and hybrid propulsion systems for hybrid tugboat in maritime applications. The conventional system, depicted in the top diagram, consists of a main engine connected to a shaft, Zpeller, and an auxiliary generator to manage the hotel load. The hybrid system, shown in the bottom diagram, integrates a motor/generator and a battery into the propulsion chain. This system allows for a smaller main engine, with the motor/generator and battery providing additional power as needed. The auxiliary generator remains in place to handle the hotel load, while the hybrid configuration enhances efficiency and reduces emissions by optimizing the power sources.

 

The Challenges of adopting green hybrid tugs

The promises of adopting green hybrid tugboat are many, but there are also some downsides, both when it comes to hybrid electric tugboats which rely on batteries, and when the hybrids rely on non-conventional fuels. 

The very first downside, for all hybrid tugboats, is the need to invest on two propulsion systems and their maintenance. In the case of electric hybrid systems, for example, these have higher start-up costs due to the expensive Battery Energy Storage Systems. Additionally, crew training for these highly automated systems can be costly. And the need for significant space to install batteries also adds to the vessel’s weight.

But, when it comes to relying on alternative fuels, instead, these might not be as green as expected. If Hydrotug 1 or the Japanese ammonia-fueled tugboat are taken in examination, it is arguable that their reliability on hydrogen is a downside because this is very energy-intensive to produce and difficult to transport. Despite this, hydrogen produces no emissions when burned, and it can even be produced in an entirely green way, through sustainable processes or renewable resources. This shows the importance of assessing “well-to-wake” and “tank-to-wake” emissions to understand the environmental impact of fuels when evaluating the performance of a hybrid tugboat.

But, apart from the disadvantages, the benefits of hybrid tugboats are the primary reasons why they are attracting owners and operators globally. And with thorough data analysis, research, and development, companies will be able to elevate the hybrid sector to its full potential.

Operational Profiles and Data Utilization

Hybrid propulsion technology has been deployed on tugboats to reduce emissions and enhance the efficiency of operation. The operational profile of a vessel plays a significant role in determining the efficiency and emissions of hybrid propulsion systems. By analyzing and optimizing these profiles, maritime operators can improve fuel efficiency and reduce emissions. Continuous monitoring and optimization of operational profiles are vital in achieving the full potential of hybrid tugboats. Doing this in the right way results in an improved performance of the ship in terms of fuel consumption, emission regulation, operational flexibility, and reduced noise and vibration.

Operational efficiency of hybrid electric tugboats can be improved, for example, by implementing power management strategies that are able to optimize the running hours of the engines to run them at optimum efficiency. Or also, by knowing when to change the primary source of energy for the propulsion between high and low-speed operations.

Conclusion - A Greener Future with Hybrid Propulsion

In conclusion, the potential of hybrid propulsion in reducing emissions and improving efficiency is immense. These green hybrid tugs have demonstrated benefits in lowering fuel consumption, cutting emissions, and improving operational performance. By integrating alternative fuels, advanced battery systems, and data analytics, hybrid tugboats can significantly lower their environmental impact while maintaining high operational efficiency. 

Continuous innovation and effective data utilization are essential in maintaining and enhancing their performance. As the maritime sector increasingly pursues carbon reduction initiatives, the number of hybrid tugboats worldwide is projected to grow significantly. The maritime industry is poised for a greener future, driven by the adoption of hybrid propulsion technologies.
