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.

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.

The Impact Of CSRD And ESRS On Maritime Sustainability Reporting


Unpacking the Regulatory Shifts and Their Implications for Maritime Companies and Tugboat Operators

In the wake of the European Union’s ambitious Green Deal, maritime companies, including tugboat operators, are transitioning into a time when sustainability reporting will become the norm. The driving force in this change is the Corporate Sustainability Reporting Directive (CSRD) and the European Sustainability Reporting Standards (ESRS), both of which set out to transform how companies report on their environmental, social, and governance (ESG) metrics. This article delves into the regulations and unpacks how they will impact the maritime sector, helping the industry understand the road ahead. 

Why the CSRD and ESRS?

The CSRD mandates that all large companies and listed SMEs in the European Union adhere to common mandatory standards for sustainability reporting. To operationalize these requirements, the ESRS were developed, providing detailed guidelines that ensure uniform and comprehensive disclosure across a range of ESG issues. These standards are designed to make the sustainability reports more comparable and reliable, thereby enhancing transparency in how companies impact the environment and society. Thus, while the CSRD sets the stage for comprehensive sustainability reporting by large companies and listed SMEs across the EU, the ESRS provides the detailed script and guidelines, ensuring each actors’ performance is consistent and can be effectively evaluated. 

In short, the CSRD and ESRS have two aims. Firstly, they are designed to enhance clarity for investors and, secondly, for aligning corporate activities with the EU’s Green Deal agenda. This dual-purpose aims to standardize sustainability disclosures, which will enable investors and other stakeholders to make more informed decisions based on the sustainability performance of companies, in turn, further redirecting capital towards sustainable businesses. Not only does this encourage companies to adopt greener and more socially responsible practices, it also contributes to the EU’s objective of achieving a sustainable and inclusive economy. 

Which companies need to report under CSRD requirements?

The CSRD will be implemented in phases, starting with companies already subject to the Non-Financial Reporting Directive (NFRD). Gradually, the scope will expand to include all large companies, listed SMEs, and eventually, certain non-EU entities by 2028. This phased approach allows companies time to adapt to the new requirements but also places immediate pressure to start preparing for compliance.

 

 

CRSD Timeline for Maritime Industry
CRSD Timeline for Maritime Industry

Implementing the ESRS

The ESRS went into effect on January 1, 2024, affecting all companies previously subject to the Non-Financial Reporting Directive (NFRD). Regarding the newly adopted legislation, companies are mandated to report on the following key points: 

Companies must report on their emissions, quantitatively and qualitatively. Emission reporting concerns direct emissions (Scope 1), indirect emissions from purchased energy (Scope 2), and other indirect emissions (Scope 3), which include emissions along the value chain, such as those from purchased goods and services, business travel, employee commuting, waste disposal, and use of sold products. For the first reporting year, a company with less than 750 employees may omit scope 3 emissions. In addition to the quantitative metrics on their GHG emissions, companies must provide qualitative information about the data they report. This is to contextualize the data, and provide an overview of the structures in place to manage environmental issues. 

The principle of double materiality in the ESRS ensures comprehensive sustainability reporting by addressing financial and impact materiality. Financial materiality focuses on how ESG issues affect a company’s financial performance, influencing investor decisions and economic outcomes. Impact materiality assesses the effects of a company’s operations on society and the environment, considering the significance of the company’s activities on external factors like ecological health. Companies must identify which emissions hold material significance from these perspectives and report them appropriately. 

Finally, to ensure compliance and reliability of the reported data, ESRS disclosures are subject to verification. Companies are required to implement robust internal processes to manage data gathering, verification, and reporting, and these processes may also need to be audited by certified professionals. Given the comprehensive nature and novelty of the ESRS, companies might still be adjusting their systems to fully align with these standards. Support and guidelines from the European Financial Reporting Advisory Group (EFRAG), which developed the ESRS, along with assistance from national regulators, is expected to aid companies in this transitional period. 

Implications for the Maritime Sector? Sector-specific ESRS

The CSRD and the newly adopted ESRS will change reporting of GHG emissions for the maritime sector. The legislation recognizes that sectors are often exposed to similar sustainability-related risks, just as they often have similar impacts on society and the environment. Therefore, sector-specific standards will also be developed under the ESRS, which will provide the necessary clarity and guidance to address the unique challenges faced by the maritime transportation industry when reporting its emissions. According to Article 29b(1), third subparagraph, of the Accounting Directive sets the adoption date of the sector specific ESRS by mid-2026. The maritime sector must wait for reporting standards that provide clearer guidance, and for now rely on the general guidelines of the CSRD. 

While the ESRS sector-specific reporting standards are not yet known, the classification of the sector is. The ESRS define marine transportation as consisting of undertakings that provide deep-sea, coastal, and/or river-way freight shipping services. Key activities include transportation of containerized and bulk freight, including consumer goods and a wide range of commodities. This also includes the transport of passengers or freight over water, whether scheduled or not. Also included are the operation of towing or pushing boats, excursion, cruise or sightseeing boats, ferries, water taxis etc. The section below will elaborate in-depth on how tugboats might are affected. 

Impact of CSRD on Tugboat Operators – Materiality and Indirect Emissions

In line with the criteria for large companies and publically listed SMEs listed in the timeline, it is reasonable to conclude that a relatively small portion of tugboat operators meet these criteria, and will thus be directly impacted by the CSRD. Nonetheless, although the CSRD first has to be reported by large and EU-listed companies, the entire value chain of these companies are indirectly impacted. As part of the value chain of larger companies, who are subject to report on the CSRD, tugboats are considered part of their indirect, scope 3, emissions. 

The directive states that information about each actor in the value chain is not required unless it pertains to ‘material’ upstream and downstream value chain information. The concept of “materiality” plays a central role here, indicating that emissions from tugboats would need to be included if they are significant in relation to the vessel operator’s environmental impact. In analyzing the materiality of tugboat operators, companies need to consider their environmental and financial impact. First, if greenhouse gases emissions and other pollutants of tugboat operators contribute significantly to the company’s total environmental impact, they are likely to be deemed material. Next, financial risks and opportunities associated with tugboat operations, such as potential costs related to fuel consumption, emissions regulation compliance must be considered, along with the potential for investment in cleaner technologies. Thus, the emissions from tugboat operations could be substantial enough to warrant consideration under the CSRD’s scope of reporting, particularly if the towage operations have, for example, inefficient fuel usage. In the end, it depends on the context of the company and their tugboat operator. 

Data transparency is required for the whole value chain, and companies are encouraged to strive for the most accurate data possible. Data from other parties in the value chain need to be sent at the request of firms, as these emissions must be included in their annual sustainability reports under the CSRD. Only in cases where precise data is not available or practical to obtain, are companies allowed to use estimates based on average consumption. This can involve using established industry averages, emissions factors, or other estimation methods that reflect the typical emissions produced by such activities. This is particularly important for emissions sources where the company does not have direct control or complete data visibility, such as those involving third-party services. 

It is clear that the scope 3 emissions still leave some uncertainties, specifically regarding the definition of materiality and data transparency. For third-party services such as tugboats and other port operations, answers are likely provided once the sector-specific ESRS guidelines are out by 30 June 2026. While it is possible that the emissions of tugboats can be estimated, it is more likely that they will require accurate measurement, given this is possible. Lastly, a committee has been established to review the act at least every three years, suggesting the framework is evolving. This could lead to more specific guidelines on reporting emissions, as the CSRD is implemented. 

Challenges and Opportunities for Tugboat Operators

Precisely calculating emissions from maritime operations, including those from tugboats, presents several significant challenges that can contribute to administrative burdens for companies. Firstly, the variability in tugboat operations – affected by factors such as differing fuel types, operational conditions, and aging fleets – complicates the accurate measurement of emissions. Collecting consistent and reliable data across diverse operational scenarios demands robust tracking systems and potentially significant investments in technology and training.


The administrative load is further increased by the need for ongoing data verification to meet reporting standards under regulations such as the CSRD. This involves not only the initial setup of measurement and reporting systems, but also their continuous management and updates to comply with evolving standards and technologies.


At the same time, the pursuit of precise emissions calculations opens substantial opportunities for the maritime sector. Enhanced accuracy in emissions reporting drives greater transparency, providing clear insights into environmental impacts and operational efficiencies. This visibility can lead to better-informed decisions by stakeholders, including investors, regulators, and customers, who are increasingly valuing sustainability.

 
The focus on detailed emissions data encourages companies to adopt more sustainable practices. Identifying specific sources and amounts of emissions allows for targeted interventions, such as upgrading tugboats to more efficient technologies or optimizing operational practices to reduce fuel consumption and emissions. Over time, these improvements contribute to a more sustainable maritime sector, aligning with global environmental goals and potentially leading to cost savings through more efficient operations.

Competitive Advantage Through Transparent Emissions Data

Having transparent and reliable emissions data provides a distinct competitive advantage in the maritime sector. As regulatory and consumer expectations shift towards greater environmental responsibility, companies that can demonstrate effective emissions’ management through accurate data not only meet these demands but also differentiate themselves in the market. Transparent emissions reporting allows companies to showcase their commitment to sustainability, enhancing their reputation and appeal to eco-conscious clients and partners. This transparency, coupled with competitive service pricing, positions these companies as leaders in sustainability, making them more attractive in tender processes and partnerships where environmental impact is increasingly a deciding factor.

The implementation of the CSRD is indicative of a broader trend toward stricter environmental regulations and the expectation of more detailed data transparency. This regulatory shift encourages companies and their suppliers to not only comply with existing mandates, but to anticipate and prepare for future, more stringent requirements. By proactively enhancing their data collection and reporting systems, companies can ensure they remain adaptable and resilient in a regulatory landscape that is likely to evolve with increasing focus on sustainability. This forward-thinking approach not only minimizes future compliance risks, but also positions companies to take advantage of emerging opportunities related to sustainability advancements and innovations.

Conclusion

It is important to remember that the CSRD seeks to enhance ESG reporting and improve transparency across companies. While there might be some questions in the short term, the main objective is to ensure that businesses give stakeholders complete and credible ESG information in the future. Therefore, it is necessary to stay updated of any changes to the reporting requirements, while attempting to adapt to the existing. Not only does the CSRD and ESRS enhance transparency and accountability but also propel maritime companies, including tugboat operators, toward integrating robust ESG practices into their core operations.

The enactment of the CSRD and the ESRS signifies a shift in the maritime sector, impacting large and small companies. As the industry moves toward heightened transparency and standardized reporting, tugboats, as integral components of the maritime value chain, must adapt to these changes, ensuring their operations are accounted for within the broader scope of indirect, Scope 3 emissions. This requirement not only fosters greater accountability but also opens avenues for tugboat operators to enhance their sustainability measures.

Decoding Tugboat Fuel Consumption: How LionRock Maritime's Data-Driven Model is Revolutionizing the Maritime Industry

Understanding and managing fuel consumption is a critical aspect of tugboat operations. Efficient fuel usage not only helps to reduce costs but also contributes to the wider goal of environmental sustainability. However, accurately quantifying this variable cost remains a significant challenge in the industry. Fuel efficiency impacts both the financial bottom line and the environmental footprint of tugboat operations, thus making it a key factor in the industry’s drive towards more sustainable practices. Furthermore, as reported by Professional Mariner, fuel costs can represent up to 30% of a tugboat’s operating cost, making it a prime area for potential cost savings and efficiency improvements. (1)

Speed Distribution Data of Tugboats by Week

Explaining the Variables Affecting Ship Fuel Consumption

Fuel consumption in tugboats is influenced by a myriad of factors, including environmental conditions, tugboat specifications, job execution methods, and characteristics of the assisted ship. Environmental conditions such as wind speed, direction, currents, and wave height can significantly alter fuel consumption. According to an IOP Conference Series study, environmental factors could increase fuel consumption by up to 20% (2). The tugboat’s specifications, such as engine type and efficiency, hull design, and displacement, are also crucial considerations.

Discussing Traditional Tug Boat Fuel Consumption Calculation Methods

Traditionally, operators attempt to quantify fuel costs by dividing total fuel expense by the tugboat’s running hours, yielding a rough average. Sophisticated monitoring systems installed on vessels are also used, but these bring high costs and the complexity of their implementation and maintenance. While these systems provide real-time fuel consumption data, their high upfront costs and the need for continuous monitoring and maintenance make them less accessible and appealing to many operators. As reported by the Professional Mariner, installing such systems can cost up to $25,000 per tug (1).

The Shortcomings of Current Techniques and the Need for Innovation

These traditional methods fail to provide a comprehensive view of fuel consumption, unable to account for operational fluctuations or the complex interactions between influencing factors. Hence, the maritime industry requires a more sophisticated, cost-effective, and user-friendly method to estimate fuel consumption.
