A recently published study ‘Invisible ship tracks show large cloud sensitivity to aerosol’ has found air pollution from vessels having a larger effect on climate than previously thought, according to the University of Oxford on Thursday (6 October).

The study used a global database of ship routes containing the locations of almost all ships at a given time: more than two million ship paths over six years.

The research team analysed data on ship emissions as a model system for quantifying the climatic effect of human aerosol emissions in general.

Sometimes, when a ship passes underneath a cloud, its aerosol emissions brighten the cloud in a long line, similar to a contrail.

These so-called ship tracks have been studied previously, however the vast majority of ships leave no visible tracks. This was the first study to provide a quantitative measure of the impact of invisible ship tracks on cloud properties, and thus their cooling effect.

Brighter clouds reflect more of the sunlight that strikes them, deflecting it from the earth’s surface. However, it is currently unclear how large this cooling effect is, particularly if the cloud brightness change cannot be seen in satellite images.

Key findings of the study:

Invisible shipping tracks had a clear impact on the properties of clouds they polluted.
Surprisingly, the specific effects were different to those of visible shipping tracks.
Invisible ship tracks showed a smaller increase (roughly 50% less) in the number of droplets in the clouds, but the amount of water increased more, compared to the effect of visible tracks. This implies that for a given increase in droplets, the increase in water is larger than thought, equating to a greater cooling effect.
The same may be true for aerosol emissions more generally – clouds may react more strongly to air pollution than previously thought, getting brighter and having a stronger cooling effect.

Singapore: GCMD introduces new technique for FAME bio bunker fuel fingerprinting

Fingerprinting identifies feedstock origins of FAME-based biofuels used in shipping industry; can be used as a potential tool to detect fraud in marine fuel supply chains and ensure biofuel authenticity.

Singapore: GCMD introduces new technique for FAME bio bunker fuel fingerprinting

The Global Centre for Maritime Decarbonisation (GCMD) on Monday (2 December) released its latest report, presenting a new technique that creates a fingerprint for Fatty Acid Methyl Esters(FAME) bio bunker fuels.

This fingerprint identifies the feedstock origins of the FAME-based biofuels used in the shipping industry.

GCMD said FAME fingerprinting is needed as the shipping sector is increasingly using biofuels, such as FAME, to reduce its GHG emissions. With that, concerns have arisen regarding the legitimacy of biofuels and whether they are truly sustainable.

Industry bodies are seeing a rising number of cases mislabelling biofuels purported to be made from recycled oils and fats, while suspicions persist that they might be produced from cheaper and less sustainable virgin oils.

“To address these concerns, FAME fingerprinting can be used as a potential tool to detect fraud in marine fuel supply chains and ensure biofuel authenticity. By providing a physical validation method that complements existing certification schemes, FAME fingerprinting can help justify the green premium with genuine environmental benefits and safeguard the integrity of marine fuels supply chain,” GCMD said.

FAME fingerprinting is based on the principle that the fatty acid profile of FAME is unique to its feedstock and can be preserved during feedstock transesterification to produce FAME. The "fingerprint" can then be compared against a database of known fatty acid profiles to identify the feedstock origin.

GCMD worked with VPS who modified existing fuel testing methods to carry out sample analyses using a gas chromatograph with flame-ionisation detection, an instrument commonly found in fuel test laboratories.

The analysis takes about an hour, comparable to the turnaround time for current marine fuel quality testing in the supply chain.

“We have tested this method on a variety of FAME samples from different suppliers, including virgin oils, used cooking oils, palm oil mill effluent, beef tallow and food waste and were able to identify the feedstock origins for each sample,” GCMD added.

Manifold Times previously reported Captain Rahul Choudhuri, President, Strategic Partnerships at marine fuels testing company VPS, forecasting the use of finger printing technology today will likely establish a blueprint of how future alternative bunker fuels’ feedstocks are authenticated.

Captain Choudhuri said this when he gave an update of VPS’ biofuels finger printing trials with GCMD.

PLAGEN to produce and supply green methanol bunker fuel with Latvia plant

South Korean clean energy firm PLAGEN on Friday (29 November) signed an MOU with Latvian company, AE Risinājumi, for the production of green methanol in Latvia at the “2024 Latvia-Korea Business Forum” hosted by the President of Latvia.

The agreement will result in the construction of Latvia's first commercial-scale green methanol production plant, which will supply green methanol to ships in the EU's maritime fleet, contributing to the reduction of greenhouse gas emissions from maritime transportation.

PLAGEN's MoU aims to produce 20,000 metric tonnes (mt) of green methanol per year and will begin feasibility studies in the first half of 2025, and full-scale production will begin in 2028.

With 53% of Latvia's land area covered by forests, timber production and wood processing make a significant contribution to Latvia’s economic production, which generates a large amount of forest residues and wood wastes. In addition, Latvia also has an abundance and low price of renewable electricity from wind power.

Latvia is one of the most competitive countries in the European Union, as it can produce clean methanol at a competitive price by using abundant wood waste as a raw material and renewable electricity from cheap wind power.

The use of abundant forest residues and wood wastes as a feedstock and cheap renewable electricity from wind power makes it possible to produce green methanol with a competitive price, making Latvia is one of the most competitive countries in the EU.

In the European Union, the European Emissions Trading Scheme (EU-ETS) will come into effect in 2025, requiring shipping companies to purchase carbon credits for their greenhouse gas emissions.

In addition, the EU is implementing FuelEU Maritime, which aims to reduce greenhouse gas emissions by 2% below the 2020 average by 2025 and 80% by 2050. This is expected to result in an energy transition to green methanol.

In July 2023, the International Maritime Organization (IMO) adopted a revised strategy that calls for reducing greenhouse gas (GHG) emissions from ships to net-zero by or around 2050, and plans to introduce full-scale regulations from 2027, and shipping companies have begun ordering methanol-powered ships fueled by green methanol, a carbon-neutral fuel.

“We expect to start producing green methanol in Latvia in 2028, which will reduce greenhouse gas emissions from EU maritime transport vessels and contribute significantly to the revitalization of the Latvian economy and national energy security,” said John Kyung, CEO of PLAGEN.

In November 2024, PLAGEN completed the purchase of an industrial complex and received a government permit for the construction of the country's first green methanol plant in Dongjeom Industrial Complex in Taebaek City, Gangwon-do.

The project, which will produce 10,000 mt per year, is scheduled to begin construction in the first half of 2025 and begin production in the second half of 2027.

Molgas commences LNG bunkering operations in United Kingdom

Molgas Group on Friday (29 November) said it successfully completed the first LNG bunkering of the MV Glen Sannox since the ship was handed over to CalMac Ferries Limited last week, marking its entry into the United Kingdom.

“We would like to thank CalMac Ferries Limited and Ferguson Marine (Port Glasgow) Limited for their trust and long-term collaboration,” the firm said in a social media post.

“This project not only represents a significant step forward in the adoption of cleaner fuels in the maritime industry of the United Kingdom but also for the expansion of our Pan-European Supply Network for the Marine Segment to receive (bio)LNG via various supply assets across multiple countries and ports.”
