Classification society DNV on Tuesday (21 February) released a technical article to clarify the regulatory status and other considerations on the usage of such fuels after seeing an increasing interest in biofuel bunkers or biofuel blends. The following is an excerpt of it:

Relevant for shipowners, managers, seafarers, maritime training institutes and flag states.

DNV has received many requests regarding the safe operation of ships using biofuels and/or biofuel blends and how to comply with international regulations when using these fuels. Below is a summary of regulatory issues, safety and operational aspects:

Types of biofuels

Three types of biofuels are relevant for maritime shipping:

FAME (Fatty acid methyl ester) is produced from vegetable oils, animal fats or waste cooking oils by transesterification, where various oils (triglycerides) are converted to methyl esters. This is the most widely available type of biodiesel in the industry and is often blended with regular marine diesel. International standards: ISO 8217:2017, EN 14214, ASTM D6751, EN 590
BTL (Biomass to liquid) fuels are synthetic fuels that are produced from biomass by means of thermo-chemical conversion using the Fischer-Tropsch process or the methanolto-gasoline process. The final product can be fuels that are chemically different from conventional fuels such as gasoline or diesel but can also be used in diesel engines. International standards: EN 16709, EN 15940
HVO/HDRD (Hydrogen vegetable oil / Hydrogenation derived renewable diesel) is the product of fats or vegetable oils – alone or blended with petroleum – refined by a hydrotreating process known as fatty acids-to-hydrocarbon hydrotreatment. Diesel produced using this process is often called renewable diesel to differentiate it from FAME biodiesel. HVO/HDRD can be directly introduced in distribution and refuelling facilities as well as existing diesel engines without any further modification. International standards: ASTM D 975

Currently, FAME is the most prominently used biofuel in marine applications. It is either used in blends with traditional petroleum fuels or as 100% biofuel

Biofuels and their effect on GHG regulations

The Maritime Safety Committee has invited all relevant IMO bodies to assess their respective involvement in the human element within their remit and report back to the committee with a view to devising an outline for a holistic approach on the human element, taking into account resource and budgetary implications within the IMO. In this regard, HTW 9 invited member states and other interested parties to submit papers to HTW 10 in February 2024.

Model training courses

IMO model courses intend to assist instructors in developing training programmes for seafarers as per the International Convention of Standards of Training, Certification and Watchkeeping for Seafarers (STCW), 1978. The model courses are subject to regular review to ensure that they are consistent with the current IMO instruments and reflect best practices and modern technologies.

HTW 9 validated a large number of model courses, as there was a backlog due to time constraints in the remote sessions of the last two years.

The following model courses are now validated and will be published soon:

EEDI and EEXI
The EEXI and EEDI only consider the so-called tank-to-wake approach, meaning that only the carbon content of standard reference fuels the vessel is designed for is considered. For that reason, the usage of biofuels has no effect on the EEXI or the EEDI.
CII (Carbon Intensity Index)
In view of IMO DCS reporting as well as the CII calculation methodology – as per the 2022 SEEMP Development Guidelines, Resolution MEPC.346(78), and the CII Calculation Methods Guidelines, Resolution MEPC.352(78) – in case of fuel types not covered by the guidelines, the conversion factor Cf is to be obtained from the fuel oil supplier and supported by documentary evidence.
Any non-standard approach in the determination methodology of tank-to-wake emissions for biofuels is subject to acceptance by the vessel’s flag administration as well as the RO handling the IMO DCS and CII verification on behalf of the flag, where an addition to the list of fuel types used and applicable conversion factors needs to be reflected in the SEEMP Part II.
In case of acceptance of the flag state administration, the usage of biofuels, also in form of blends with traditional petroleum fuels, will have a significant impact on the reduction of the CII value
EU MRV
As per Regulation (EU) 2015/757, in case of alternative fuels, the monitoring plan shall contain “the methodologies for determining the emission factors, including the methodology for sampling, methods of analysis and a description of the laboratories used, with the ISO 17025 accreditation of those laboratories, if any”. It is worth noting that Directive (EU) 2018/2001 (EU RED II), Annex V, Part C provides a methodology for greenhouse gas emissions from the production and use of transport fuels, whereas per point 13, the CO2 emissions of the fuel in use shall be taken to be zero for biofuels and bioliquids.
The proposed method for calculation of the CO2 emission factor for biofuel and biofuel blends should be included in the ship’s MRV Monitoring Plan along with an addition to the list of fuel types used and method for determination of fuel density, with the revised plan being subject to acceptance from the Accredited Verifier, such as DNV.

EDF, LR and Arup launch tool scoring ports’ potential to produce and bunker electrofuels

Lloyd’s Register (LR) Maritime Decarbonisation Hub and Environmental Defense Fund (EDF), in collaboration with Arup, on Tuesday (28 November) introduced the Sustainable First Movers Initiative Identification Tool, a system to help shipping stakeholders align investment decisions that support the maritime energy transition away from fossil fuels.

The tool, which is presented in a preliminary findings report – The Potential of Ports in Developing Sustainable First Movers Initiatives – scores a port’s potential to produce and bunker electrofuels while delivering local environmental and community benefits in alignment with the global temperature target of 1.5 degrees Celsius set by the Paris Agreement.

“Ports can play an important role in kickstarting shipping’s decarbonisation process even before global policies are established,” said Marie Cabbia Hubatova, Director, Global Shipping at Environmental Defense Fund.

“By considering the impact sustainable first mover initiatives can have on port-side communities, climate, environment and economies, resources can be better directed to locations where these initiatives will make the biggest difference.”

With close to two billion people living near coastal zones globally, the role of, and impacts on local port communities must be intentionally considered as the sector decarbonises globally. Ports can play a crucial role in ensuring shipping decarbonisation efforts are done in a way that has positive impacts on port communities.

The preliminary phase of the Sustainable First Movers Initiative Identification Tool analyses 108 ports in the Indo-Pacific region according to five criteria including land suitability, air quality, renewable energy surplus, economic resilience and ship traffic.

It is also applied to three different port scenarios, including ports exploring fuel production and bunkering, ports exploring fuel exports, and ports exploring fuel imports and bunkering. The combined criteria and scenario evaluation determines which ports have the greatest potential (high potential) for sustainable first mover initiatives to lead to significant emissions reductions and positive impacts in nearby communities, such as improved air quality and economic resilience.

“The transition to clean energy supply for shipping can be achieved only if stakeholders act together. Identifying potential port locations is the first step in this process,” said Dr Carlo Raucci, Consultant at Lloyd’s Register Maritime Decarbonisation Hub. “This approach sets the base for a regional sustainable transition that considers the impacts on port-side communities and the need to avoid regions in the Global South lagging behind.”

Regions in the Global South are fundamental in driving the decarbonisation of shipping. To make this transition effective, the rate at which different countries adopt and scale up electrofuels must be proportional to the difference in capital resources globally to avoid additional costs being passed on to local communities. Sustainable first mover initiatives can play an important role in making this happen by ensuring the sector’s decarbonisation is inclusive of all regions and by engaging all shipping stakeholders, including port-side communities.

“There’s a huge opportunity for early adopter shipping decarbonisation initiatives to unlock benefits for people and planet – shaping the way for a more equitable transition in the 2030s,” said Mark Button, Associate, Arup. “Our collective approach shows that taking a holistic view of shipping traffic, fuel production potential and port communities could help prioritise action at ports with the greatest near-term potential.”

The tool can be customised according to stakeholders’ needs and goals and is dependent on scenario desirability. The next phase of this work will include the selection and detailed assessment of 10 ports to help better understand local needs and maximise the value offered by sustainable first mover initiatives.

LR and EDF carried out a joint study on ammonia as shipping fuel, and LR and Arup have collaborated on The Resilience Shift study focused on fuel demand for early adopters in green corridors, ports, and energy systems, amongst many other projects.

Wärtsilä signs agreement for first zero-emission high speed ferries in US

Technology group Wärtsilä on Tuesday (28 November) said it has signed a strategic partnership agreement to provide its Fleet Electrification and Systems Integrator Services for a project to build the first zero-emission high speed ferries in the United States.

The fully electric vessels will be built for San Francisco’s Water Emergency Transportation Authority (WETA), the operator of the San Francisco Bay Ferry system.

The project, and several others Wärtsilä will work on under this partnership, are a part of the agency’s Rapid Electric Emission-Free (REEF) Ferry Program, a phased decarbonisation of high-speed, high-capacity ferry service in the San Francisco Bay.

Wärtsilä will work within the WETA project team to finalise vessel and charging system concepts.

“We’re proud to operate the cleanest high-speed ferry fleet in the nation, but a zero-emission future for our system is within reach,” said WETA Executive Director, Seamus Murphy.

“Wärtsilä’s expertise and experience will be incredibly valuable given the complexity our ferry decarbonisation program entails.”

“This is a major project within the maritime sector’s journey towards decarbonisation, and we are proud to be a part of it,” said Hanno Schoonman, Director of sales for AMER region, Wärtsilä Marine Power.

“Wärtsilä joins an industry leading team tasked to develop newbuild battery electric vessels that combine innovative technology and sustainable practices. Wärtsilä is well qualified to provide this project support, and this agreement is a clear endorsement of our strong track record in systems integration and emission-free propulsion.”

After completing the conceptual phase, WETA will move on to the initial construction phase of a multi-vessel programme. This phase will involve the building of three smaller ferries with a capacity of approximately 150 passengers each and two larger ferries capable of carrying at least 300 passengers.

Additionally, the scope of this phase will encompass the inclusion of battery charging floats. The construction of the first electric-powered vessel is slated to commence before the conclusion of 2023, with commercial operations expected to launch in 2025.
