Standard Club publishes FAQs on decarbonisation and alternative bunker fuels

Members need to consider overall fuel management strategy and policies, potential investment in vessel modifications, and personnel training, amongst others.




post 53417

The Standard Club on Thursday (9 June) said it has published a document of frequently asked questions (FAQs) with answers relating to decarbonisation and alternative fuels.

The following are extracts from the full copy of the FAQs: 

  1. A brief overview of the current situation

The maritime industry is embarking on a major transition from conventional to zero or carbon neutral fuels driven by the pressure to decarbonise. The transition will not take place over night and will have a significant impact on costs, asset values, and earning capacity. The industry participants will need to understand the drivers and implications now to be able to plan accordingly and assess the associated risks.

Whilst regulations will set direct requirements that shipowners must comply with, the public as well as third-party stakeholders (including governments, classifications societies, ports, shipyards, banks and cargo owners) will increasingly have high expectations that will require transparency and promote decarbonisation.  Access to finance for newbuilds will also be dependent on shipowners being able to demonstrate that they can meet decarbonisation targets.

  1. Is the IMO Initial Strategy regime mandatory? If so, how will it be enforced?

The Initial Strategy itself is not mandatory. However, the IMO can adopt measures to implement the Initial Strategy by amending existing conventions which are mandatory in many jurisdictions (such as the International Convention for the Prevention of Pollution from Ships (MARPOL).

The requirements imposed by the revisions to MARPOL (see para 5 below) are mandatory for all cargo and cruise vessels trading internationally and which are above the gross tonnage specified in the amendments and registered in a MARPOL-signatory country. Enforcement of such amendments will be through flag states which are parties to MARPOL.

  1. Has the IMO adopted measures in furtherance of the Initial Strategy objectives?

Yes. In June 2021, the IMO’s Marine Environment Protection Committee (MEPC) held its 76th session (referred to as ‘MEPC 76’) and adopted measures aimed at the Initial Strategy objectives. These measures include amendments to Annex VI of MARPOL.

The revised Annex VI requires ships over 400 GT and operating internationally to calculate their Energy Efficiency Existing Ship Index (EEXI). The EEXI is a design rating which will reflect the ship’s energy efficiency as compared to a baseline target for ships of that type and size. The EEXI requirements are in addition to the existing Energy Efficiency Design Index (EEDI) requirements which are applicable to the design and construction of new ships (see no. 7 below). The EEXI baseline target for a vessel will be based on a reduction factor expressed as a percentage relative to the EEDI baseline set for new ships of the same type and size. Existing vessels will be required, among other things, to have an actual calculated EEXI (‘attained EEXI’) below the targeted EEXI (‘required EEXI’) for the vessel. The EEXI requirements do not mandate modifications to existing ships, but realistically, modifications may be necessary to achieve the required EEXI for a particular ship.  

MARPOL Annex VI also requires ships over 5,000 GT to establish an annual operational carbon intensity indicator (CII) and rating. Shipowners must calculate annually a CII for each ship accounting for cargo carried. The CII rating scale will be A, B, C, D, or E (with A being the best). The CII scale will require progressively higher efficiency standards each year, through 2030. Shipowners therefore should also develop plans to cut the CII to reach the progressive ship-specific targets whereby the CII of a ship is reduced annually. The flag state will compare a ship’s reported CII to its target and produce the CII rating. A ship rated D for three consecutive years or E (on one occasion) will be required to submit a corrective action plan to show how a rating of C or above will be achieved.

  1. Are the EEXI, EEDI, and CII measures enough to hit the lower emission targets in the IMO’s Initial Strategy?

Some experts believe the 2030 target can be achieved through the EEXI, EEDI, and CII measures. However, it is widely accepted that much more will need to be done to meet the 2050 targets. In particular, the adoption of alternative fuel technologies is required.

  1. Is there a possibility that the IMO’s GHG strategy will be revised?

Yes. Delegates at the 2021 United Nations Climate Change Conference (COP26) called for the shipping community to go further than the Initial Strategy and to aim for net zero by 2050. This was re-iterated at the seventy-seventh session of the Marine Environment Protection Committee (MEPC-77) held  from 22 to 26 November 2021.. Some member states expressed the view that the short-term measures adopted by MEPC-76 in June 2021 are inadequate to address the Paris Agreement temperature goals and that more efforts are needed. Consequently, MEPC-77 agreed to continue the discussions on mid and long-term measures and to initiate a revision of the Initial Strategy. The final draft of the Revised Strategy is expected to be considered for adoption by MEPC-80 (scheduled for spring 2023).

  1. Are there regional or national efforts to address GHG emissions and the use of alternative fuels?

Yes, in some regions (i.e., EU) and it is likely more will follow.

The European Union

The EU is moving ahead with its own plan to reduce GHG emissions from the shipping sector. For example, since 2018, large ships over 5,000 GT loading or unloading cargo or passengers at ports in the European Economic Area have had to monitor, report, and verify CO2 emissions (EU-MRV). Further, in July 2021, the European Commission announced its ‘Fit for 55’ package of proposals. The proposals are intended to reduce the EU’s total GHG emissions by 55% by 2030 with the goal of complete decarbonisation by 2050.. The proposals are subject to further discussion and negotiation with the European Council and European Parliament and are thus not yet finalised.

In their present form, four of the ‘Fit for 55’ proposals are relevant to shipping:

  • Emissions Trading System (ETS): The package proposes incorporating shipping in the EU’s ETS from 2023. The proposal would mandate those ships that operate within EU waters to pay for their carbon emissions with the proceeds going toward development of infrastructure for cleaner alternative fuels. The extension would apply to emissions from intra-EU voyages, to 50% of the emissions from extra-EU voyages, and to emissions from ships while at berth in EU ports. Non-compliance will result in fiscal penalties being applied and may eventually lead to the ship being banned from EU waters.
  • Alternative Fuels Infrastructure Regulation: This proposed regulation will require EU member states to provide adequate recharging and refuelling infrastructure which will effectively involve ramping up the availability of LNG by 2025 and onshore electrical power by 2030 in core EU ports.  The introduction of this regulation will involve repealing Directive 2014/94/EU on the deployment of alternative fuels infrastructure.
  • Energy Taxation Directive: This proposal would remove the tax exemption for conventional fuels used at and between EU ports as of 1 January 2023. The tax exemption presently in place for international bunkering for extra-EU voyages will remain. The tax rate for heavy fuel oil will be approximately €37 per tonne whereas the tax rate for LNG will initially be €0.6 per gigajoule. Alternative fuels will be tax exempt for a 10-year period.
  • FuelEU Maritime Regulation: The proposed regulation would impose limits on GHG emissions (including CO2, methane, and nitrous oxide) of ships of 5,000 GT and above, regardless of their flag, arriving or departing EU ports and an obligation on EU ports to become carbon neutral. If adopted, the regulation will require ships to reduce their annual GHG intensity by 2% in 2025 as compared to 2020 levels with incremental increases over the years to achieve a 75% reduction by January 2050.
  1. What are owners doing in terms of new buildings and what is the outlook?

The industry reports there is an increase in newbuilds on order that have alternative fuel systems or dual-fuel capabilities. Except for electrification in the ferry segment, the alternative fuels being used are still mainly fossil based and are dominated by LNG.

There will be demonstration projects for onboard use of hydrogen and ammonia by 2025 paving the way for zero-carbon ships, and these technologies may be ready for commercial use in four to eight years. Methanol technology is more mature and has already seen first commercial use.

A range of new technologies are emerging including fuel cells, carbon capture, and storage (CCS), as well as wind power.

As owners consider these and other technologies for their newbuilds, they will be evaluating the economic potential of fuel and energy-efficiency strategies over the lifetime of a ship. This will entail a review of the impact of the chosen fuel strategy on ship design. Considering the significant uncertainties involved over the lifetime of a ship, they will need to focus on fuel flexibility and fuel ready solutions to ease the transition and minimise the risk of investing in stranded assets.

  1. Are alternative fuels presently available in key world ports? It not, when will they be?

LNG is presently the most readily accessible alternative fuel but is still not easy to source and certainly not carbon free. LNG (Bio-LNG and E-LNG) and Biofuels are good options for transitional fuels.

Methanol is only available in limited areas and is not yet in sufficient quantities to satisfy the requirements of the industry.

For the other alternative fuels under consideration, testing, development and creation of associated infrastructure is still on-going and they are not yet readily available. 

  1. Does Standard Club have any recommendations for members at this time?

Members should be considering the different regulations that may apply to a particular vessel or fleet and the effective date of such regulations to ensure compliance. While the effective dates of the regulations is in some cases only months away, the steps for compliance require thoughtful deliberation and may require lengthy lead time for implementation. Contract reviews are highly recommended, and amendments may be required to mitigate the risk and cost of compliance. Overall, members should ensure they adopt a culture of adherence to the applicable regulations, embrace regular oversight and auditing of their compliance procedures, and maintain effective senior management oversight. Among other things, members will need to consider their overall fuel management strategy and policies, potential investment in vessel modifications and / or emerging technologies, and training of onboard and shore personnel. Members may also want to collaborate with experts and trading partners insofar as risk and cost allocation associated with GHG emission reduction practices.

Platts proposes to launch Singapore bio-bunker fuels market-based assessment

Proposal is on the back of growing interest for blended bio-bunkers in Singapore, the world’s largest bunkering hub, amid increasing pressure on the shipping sector to decarbonise.





RESIZED Singapore Flag

Platts, part of S&P Global Commodity Insights, on Tuesday (23 April) proposed to launch a new daily market-based delivered Singapore bio-bunker assessment, effective 1 August.

This proposal is on the back of growing interest for blended bio-bunkers in Singapore, the world's largest bunkering hub, amid increasing pressure on the shipping sector to decarbonise.

The new assessment would reflect marine fuel blend of biodiesel with low sulphur fuel oil. Platts would publish the Singapore bio-bunkers market-based assessment as a differential to Platts Marine Fuel 0.5% (AMFSA00), and as an outright value.

The assessment specifications would be as follows:

Platts proposes to launch Singapore bio-bunker fuels market-based assessment

Other delivery periods and volumes may be considered in the Platts Market on Close assessment process and normalised back to the above specifications.

Bio-bunkers stems must be incompliance with the EU's Renewable Energy Directive, or RED requirements, and meet sustainability requirements such as ISCC or RSB sustainability criterions.

Platts will not consider bio-bunkers that use palm oil as a bio-component.

International Organization for Standardization is revising the ISO 8217 standards to include additional requirements for blended bio-bunker. The assessment would reflect standards set in the document ISO 8217:2024 Petroleum products -- Fuels (class F) -- specifications of marine fuels, as well as standards set by Singapore's Maritime Port Authority on specifications of marine biofuels (WA 2:2022). Platts is seeking specific feedback on these standard requirements.

Platts is also seeking specific feedback on the reference density of blended bio-bunkers.

The assessment would be published on Platts Biofuels Alert (PBF2500), in the Bunkerwire Report, Bunkerwire Monthly, Biofuelscan report and Biomass-Based Diesel Report.

The new daily bio-bunkers assessment would be timestamped to 5.30 pm Singapore time and follow the Singapore publishing schedule.

Platts spot price assessments consider market information reported to Platts and published throughout the day, including firm bids and offers, transactions and indications of value. In the absence of observable spot market activity, Platts may consider other verifiable data reported. This information will be published as price heards.

At present, Platts publishes a daily cost-based B24 Singapore bio-bunkers assessment reflecting a ratio of 76% fuel oil based on Platts benchmark Marine Fuel 0.5% Bunker Dlvd Spore $/mt assessment (MFSPD00) and 24% used cooking oil methyl ester based on the Platts UCOME FOB Straits $/mt assessment (UCFCB00). This calculated price assessment will continue to be published alongside the proposed new assessment and will be renamed “Platts B24 calculated bio-bunker Singapore.”

Peninsula adds tanker “Aalborg” to supply bio bunker fuel in Port of Barcelona

Chemical tanker is capable of supplying B100, in contrast to traditional fuel barges that cannot exceed 25% bio component; also has ability to blend multiple bio feedstocks and traditional fuels on board.





Peninsula adds tanker “Aalborg” to supply bio bunker fuel in Port of Barcelona

Marine fuel supplier Peninsula on Wednesday (24 April) announced the introduction of the Aalborg, an IMO II chemical tanker dedicated to sustainable fuel distribution in the Western Mediterranean. 

The Aalborg is capable of supplying 100% biofuels (B100), in contrast to traditional fuel barges that cannot exceed 25% bio component.  

The vessel supplies FAME (Fatty Acid Methyl Esters) produced from vegetable oils and allows for neutral emissions (depending on the origin of these vegetable oils) thereby reducing a receiving vessel’s carbon footprint. 

The Aalborg will play a pivotal role in the Port of Barcelona's ongoing commitment to promoting cleaner fuel initiatives across the region.

The vessel’s ability to blend multiple bio feedstocks and traditional fuels on board, together with a certificate detailing the bio component percentage, allows ship owners to comply with impending Fuel EU Maritime regulation using the same engine.

“The importance of having a biofuel supply vessel permitted to supply up to 100% bio component, will provide Port of Barcelona users with a solution to decarbonise their activity and to fully comply with EU regulations,” explained Lluís Salvadó, president of the Port of Barcelona.

“The Port of Barcelona, as part of its Energy Transition Plan, is committed to transition and alternative fuels such as LNG, green methanol or green ammonia, as well as biofuels, which will help to reduce the maritime sector’s carbon footprint.”

Alejandro Morales Moreno, Supply Manager at Peninsula, emphasised the collaborative efforts between Peninsula and the Port of Barcelona, highlighting a shared vision for emissions reduction.

"The addition of the Aalborg creates a meaningful, new decarbonisation solution for our customers and we’re grateful to the Port Authority for facilitating its deployment in Barcelona,” he said.

Argus Media: New ISO 8217 eyes wider scope for alternative bunker fuels

New edition will incorporate specification standards for a wide range of Fame-based marine biodiesel blends up to B100, 100pc HVO, as well as synthetic and renewable marine fuels.





resized argusmedia

The 7th edition of ISO 8217, to be published in the second quarter of this year, will outline a broader integration of marine biodiesel blending, delegates heard at the International Bunker Conference (IBC) 2024 in Norway.

24 April 2024

Tim Wilson, principal specialist fuels of Lloyds Register's fuel oil bunkering analysis and advisory service (FOBAS), presented on the upcoming iteration of the ISO 8217 marine fuel specification standard, which will be released at IBC 2024. 

The new edition will incorporate specification standards for a wide range of fatty acid methyl ester (Fame)-based marine biodiesel blends up to B100, 100pc hydrotreated vegetable oil (HVO), as well as synthetic and renewable marine fuels. 

This will also include additional clauses to cover a wider scope, and briefly touch on biodiesel specifications that do not entirely align with road biodiesel EN-14214 specifications. This follows the emergence of widening price spreads for marine biodiesel blends because of specification differences and the lack of a marine-specific standard for the blends.

The new edition of ISO 8217 is also expected to remove the limit of 7pc Fame when blended with distillate marine fuels such as marine gasoil (MGO) which was in place in the previous ISO 8217:2017. 

Other changes to distillate marine biodiesel blends include changes to the minimum Cetane Index, oxidation stability alignment to be connected to either ISO 15751 for blends comprising 2pc or more of Fame biodiesel and ISO 12205 for blends comprising a Fame component of under 2pc. 

Cold-filter plugging point (CFPP) properties will be determined by the vessel's fuel storage tanks' heating capabilities and requirements will be set in place to report the CFPP for distillate marine biodiesel grades, according to the new edition of the marine fuel specification standard.

Wilson said that a minimum kinematic viscosity at 50°C will be in place for various forms of residual bunker fuel oil along with a viscosity control alerting suppliers to inform buyers of the exact viscosity in the supplied fuel. He said they have seen delivered fuel viscosity come in at much lower levels than ordered by the buyers, which was the reasoning behind the viscosity control monitoring requirement.
