The International Bunker Industry Association (IBIA) on Thursday (4 May) published an update on how IMO approval on safety guidelines could contribute to major emission reduction and the future of fuel cells as propulsion source for vessels:

It takes power to move a ship. For centuries they relied mainly on harnessing wind but at the end of the 18th century the first steam ships appeared. The first diesel-powered ships using internal combustion engines appeared more than 100 years later, early in the 20th century, while the first nuclear-powered ship started service in 1959.

This puts into context how historic it was when, in mid-September last year, the IMO’s Sub-Committee on Carriage of Cargoes and Containers (CCC 7) agreed draft interim guidelines for ships using fuel cell power installations, adding fuel cells to the short list of energy converters used to power ships.

It took around 10 years of discussion to develop the framework, intended to ensure the safe and reliable delivery of electrical and/or thermal energy through the use of fuel cell technology.

This milestone for ship propulsion received the formal stamp of approval when the Maritime Safety Committee, at its 105th session (20 to 29 April 2022), approved Interim guidelines for the safety of ships using fuel cell power installations.

The goal of these Interim Guidelines is to provide criteria for the arrangement and installation of fuel cell power installations with at least the same level of safety and reliability as new and comparable conventional oil-fuelled main and auxiliary machinery installations, regardless of the specific fuel cell type and fuel. Depending on the fuel used, other regulations (e.g. IGF Code, part A) and provisions (e.g. Interim guidelines for the safety of ships using methyl/ethyl alcohol as fuel) are applicable in addition to these Interim Guidelines.

Major emission reductions & future potential

A fuel cell works like a battery, but one that does not run out: it produces electricity and heat as long as fuel is supplied. According to the Hydrogen and Fuel Cell Technologies Office, part of the US Department of Energy, fuel cells can operate at higher efficiencies than combustion engines and can convert the chemical energy in the fuel directly to electrical energy with efficiencies capable of exceeding 60%.

Fuel cells can use a wide range of fuels and feedstocks, and they have lower emissions compared to combustion engines. If running on hydrogen, the only products are electricity, water, and heat, meaning zero emissions. 

This makes their attraction apparent in the drive to find new fuels and propulsion systems that can help shipping reduce harmful emissions; both air pollutants like sulphur and nitrous oxides, and CO2.

So, can we expect a rush of ships being converted, or built, to use fuel cells powered by hydrogen now? Maybe not just yet, as there are cost and technical barriers to overcome. So far, fuel cells have been deemed suitable mainly for auxiliary power rather than propulsion for ocean-going ships.

Then there is the question of fuel safety. We have well-established safety provisions for marine diesel fuels and LNG, and interim IMO guidelines for the use of methanol – all of which are potential fuels for fuel cells. But IMO safety provisions for ships to use hydrogen, or ammonia as a hydrogen carrier, have yet to be developed.

CCC has initiated the development of guidelines for the safety of ships using hydrogen as fuel, and MSC 105 gave it the green light to begin work on non-mandatory safety provisions for ships to use ammonia as fuel.

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.
