The North P&I Club on Monday (12 April) published an article outlining some considerations and frequently asked questions about switching to biofuel to comply with future environmental regulations; it was written by Mark Smith, Loss Prevention Executive:

Achieving the IMO’s goals on greenhouse gas emissions will require a shift in how vessels are fuelled and propelled. Amongst the options available to shipowners on meeting the IMO targets, lower-carbon fuels are likely to be a popular option – one of which is biofuels.

Switching to biofuels could be an attractive proposition to some shipowners. The conversion to biofuels – whether a blend or ‘drop-in’ (replacement) fuel – is relatively simple. Ships’ engines and transfer and storage systems will require minimal modifications from using traditional marine (fossil) fuel. The lack of availability and higher costs have been identified as barriers to adoption, but there could be positive shifts in this area too.

North has already received enquiries from shipowners who are considering using biofuels, indicating interest is growing and the shipping industry is keen to know more. We spoke to Bart Hellings and Johannes Schurmann from biofuel provider GoodFuels based in the Netherlands for expert insight. 

How do biofuels compare with fossil fuels?

Just like fossil fuels there are multiple types of biofuels and they can also differ on sulphur, density, and viscosity parameters. The heaviest marine biofuel which GoodFuels supply is MR1-100 which compares to RMD-80. Different biofuels which are closer to other product categories are also available.

How does ISO 8217:2017 cater for the latest biofuels?

It’s important to remember that ISO 8217 is a fossil fuel standard; and while it could be used as a guideline, there are missing parameters that are relevant to biofuels and others which are no longer relevant.

Are biofuels susceptible to microbial growth and what about their shelf life? 

They normally contain less than 0.05% (v/v) water which is very low. Microbial growth normally occurs when water is added to the fuel by condensation or poor housekeeping on the ship. This risk is reduced by storing in a clean fuel tank and preventing water ingress. Special additives have been developed if microbial activity is a concern and specific operational procedures will be required.

Some biofuels undergo processes where oxygen is eliminated and are perhaps even more resistant to microbial growth in terms of quality and have at least the same shelf life of fossil fuels. 

How is the quality of the biofuel assured? 

Poor quality biofuels can be very diverse in their content and characteristics. GoodFuels have found that the following helps with the overall quality:

  • Large portfolio of quality, long-term and stable supply partners
  • Use of special additives
  • Proven recipes based on five years of continuous testing which results in consistent quality – especially for higher blends

How is biofuel quality and conformity proven?

A certificate of analysis (CoA) will confirm that specifications have been met and a sustainability certificate will verify the fuel is produced from sustainable feedstocks.

The last year has shown there is higher risk of stability and compatibility issues with VLSFOs – how do biofuels compare?

Tried and tested biofuels do not appear to cause customers any more issues than fossil fuels. The issues experienced with VLSFOs have not been reported with their marine biofuels.

Are there any special tank cleaning requirements?

There are no reported problems regarding stability and compatibility when leftover fossil fuels remain in the tank. However, thorough cleaning of fuel tanks prior to use of biofuels will prevent operational problems caused by fossil fuel sediment entering the fuel system. 

What do the engine makers say?

GoodFuels has carried out extensive testing of biofuels with the top five original equipment makers (OEMs). They are now very supportive of GoodFuels’ biofuels and additional OEMs are ratifying our products on a constant basis.

What is the future of biofuels?

Advanced marine biofuels are a fast-growing alternative fuel in the marine sector. July 2020 was a record month with biofuels representing 10% of all Rotterdam HFO volumes. We expect growth to continue for this low-sulphur ‘drop-in’ fuel which can be used in existing engines with a significant CO2 reduction.

The shipping industry needs to keep its guard up. Shipowners and fuel purchasers should ensure that they are supplied only with sustainably sourced, high quality and stable products. GoodFuels can only vouch for the quality of their own products and regularly see bad quality biofuels from other suppliers with less stringent quality controls.

Poor quality-controlled biofuels can create operational issues and potential damage to main engines and generators. High repair costs not to mention the delays to cargo, commercial off-hire and lengthy disputes with charterers are all concerns. In rare cases de-bunkering may be required too. 

How does NOx, calorific value and fuel consumption compare to fossil fuels? 

The effect on NOx is still uncertain, but testing is underway together with clients, OEMs and classification societies. Calorific value can be lower than fossil fuels and therefore the fuel consumption may be slightly higher.

BHP and GCMD trial multi-feedstock B100 bio bunker fuel on bulk carrier

BHP and the Global Centre for Maritime Decarbonisation (GCMD) on Wednesday (3 June) said they have blended biofuels from two distinct feedstocks—used cooking oil and waste animal fats —and introduced the lower-emissions marine fuel into a BHP-chartered bulk carrier as part of a pilot project.

The bio-blend in the BHP and GCMD pilot is being used on a BHP-chartered bulk carrier Berge Lyngor, owned and operated by Berge Bulk, transporting BHP iron ore from Western Australia to China. When run on bio-blend, the vessel has the potential to reduce well-to-wake greenhouse gas emissions by approximately 79 per cent per voyage compared to sailing on very low sulphur fuel oil (VLSFO).

The vessel bunkered in Singapore in early May with a B100 bio-blend comprising 50 percent tallow-derived biodiesel, sourced and supplied by HAMR Energy, and 50 per cent used cooking oil (UCOME) supplied by Mitsui & Co Energy Trading Singapore (METS).

Mitsui also blended the fuel and Dan-Bunkering coordinated and executed the bunkering operation, which was performed by Global Energy’s barge MT Maple.

The BHP and GCMD pilot will assess how biofuels from multiple feedstocks can be blended, handled, and introduced under real-world operating conditions using existing used cooking oil bunkering infrastructure.

At the same time, insights from this pilot will help identify solutions to challenges related to fuel quality, handling, traceability, and onboard vessel performance.

Biofuels for global shipping today rely heavily on used cooking oil – a feedstock whose availability is approaching its projected limits. Biofuel from waste animal fats presents a promising option to expand the supply of lower-emissions marine fuels.

The outcomes of the pilot are expected to shed light on the practical steps to integrate biofuel blends from different feedstocks into existing supply chains. The diversity of biofuels will provide shipowners and operators with greater flexibility to optimise fuel procurement based on cost, availability, and lifecycle emissions performance.

Biofuels derived from different feedstocks can exhibit varying properties that may impact operations, including potential corrosion from oxidation, fuel system clogging caused by wax formation, which this pilot aims to assess.

The pilot will trace and verify the biofuel blend’s integrity aimed at bolstering confidence in emissions reductions reporting. The pilot will also provide insights into how robust tracing can support future marine fuel supply chains where biofuels from multiple feedstocks with varying lifecycle greenhouse gas emissions footprints are blended together.

This project is co-funded by the Maritime and Port Authority of Singapore under the Maritime Innovation and Technology Fund (MINT).

NYK starts one-year B100 bio bunker fuel trial on car carrier

Japanese shipping firm NYK on Tuesday (2 June) said it has commenced a one-year long-term trial involving the continuous use of 100% biofuel (B100) on an NYK-operated car carrier. 

In this trial, NYK will operate a car carrier continuously on B100 for one year to evaluate the impact on engines, fuel supply systems, and operational practices. High-purity biofuels such as B100 are known to be susceptible to degradation from oxygen, light, and heat, raising concerns about the stability of such fuels during long-term use.

In this trial, the biofuel primarily comprises FAME (Fatty Acid Methyl Ester) derived from used cooking oil and similar feedstocks.

The initiative is designed to evaluate the fuel’s effects on the vessel’s equipment and verify operational safety under real-world conditions. 

Through this effort, NYK seeks to accumulate technical expertise that will support the broader use of high-purity biofuels and further accelerate efforts to reduce greenhouse gas (GHG) emissions.

NYK has been advancing the use of biofuels through various initiatives. In 2024, the company conducted a trial using biofuel blend B24 and subsequently expanded practical usage to B30. However, the company said there remains limited global experience with the long-term continuous use of B100.

“By collecting long-term operational data through this trial, NYK aims to accumulate valuable technical insights to support both the safe operation of vessels and the wider adoption of high-purity biofuels,” it said.
