The Lloyd’s Register Maritime Decarbonisation Hub and the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping on Monday (19 April) joined forces in a new project to develop guidance around the safe use of Ammonia as a fuel.

Industry partners involved in the project include A.P. Moller-Maersk, MAN Energy Solutions, Mitsubishi Heavy Industries, NYK Line and Total.

Ammonia as a fuel is heavily debated as a suitable long-term solution for maritime as the industry transitions towards a zero- or low carbon value chain. Green ammonia can be produced from renewable power by electrolysis of H2O, ultimately making it a zero-carbon fuel. 

However, due to the extreme toxicity of the fuel, it is critical to address the safety issues of Ammonia in order to mitigate risks to people, assets and the environment.  

According to Lloyd’s Register, the overarching purpose of the project is to understand and guide the safe use of Ammonia as a fuel on board ships. 

Part of this will include developing a mature and detailed understanding of risk and safety concerns, which will be assessed through a Quantitative Risk Assessment methodology in phase one of the project. 

This will ultimately lead to the development of best practices for safeguards in design and arrangements when using Ammonia as a shipping fuel.    

The project will also determine the risk of fatality from unintended releases of Ammonia, as well as determine the risk contribution of key equipment and spaces dedicated to Ammonia storage. 

To illustrate the potential for risk mitigation measures, the project partners will assess alternate vessel designs, optimised to be fuelled by Ammonia. 

Funded by the participating partners, the project will be managed by the Maersk Mc-Kinney Moller Center for Zero Carbon Shipping and is expected to run throughout 2021. 

“In the eagerness to decarbonise the shipping sector, proper risk management is critical and safety must not become an afterthought,” said Claus Winter Graugaard, Head of Onboard Vessel Solutions, the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping.  

“This project will provide matured understanding of safety risk enabling industry guidance towards future safeguard design and adequate operational guidelines. Enabling safe and adequate deployment of ammonia as marine fuel.”

Commenting on the new project, Lloyd’s Register Decarbonisation Programme Manager, Charles Haskell said: “Shipping needs collaboration if the industry is to successfully meet the IMO 2050 targets, and this collaboration between the LR Maritime Decarbonisation Hub and the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping is a significant milestone in this journey.”

“We look forward to working with the project partners, who each represent different areas of the supply chain, in developing guidance, risk mitigation measures and best practice on using Ammonia so that we can support the safe uptake of the fuel.”

Singapore: ITOPF and Britannia P&I Club conduct table-top workshop for LNG bunker spills

The International Tanker Owners Pollution Federation (ITOPF) on Wednesday (7 May) said it held a table-top workshop with Britannia P&I Club in Singapore where attendees planned a response to a spill scenario of Liquefied Natural Gas (LNG) as part of a new training exercise called HYDRO NEXUS. 

The half-day event saw team members from Britannia successfully responding to a spill of LNG bunkers from an alternatively fuelled vessel, who were assisted by the ITOPF team on how best to approach the response, taking into account the risks and hazards presented by this substance.

“The Britannia team were guided by ITOPF’s experts on the steps of an alternative fuel and HNS (Hazardous and Noxious Substances) response, including information gathering, risk assessment, appropriate PPE selection, and use of different techniques and equipment used in these spill scenarios,” it said on its website. 

“One key component of the exercise was to demonstrate the potential impacts and claims that the P&I insurers may face during an alternative fuel/HNS incident. Teams collated costs for loss of life and personal injury, clean-up and preventive measures, property damage, economic loss and environmental damage claims.”

GCMD and ADB to advance green financing pathways for maritime decarbonisation

The Global Centre for Maritime Decarbonisation (GCMD) on Thursday (8 May) announced a knowledge partnership with Asian Development Bank (ADB), signed during the launch of its Sustainable and Resilient Maritime Fund (SRMF) at its annual meeting in Milan.

The partnership—GCMD’s first with a multilateral development bank —complements its diverse pool of centre-level partners. 

The partnership aims to advance green financing pathways that support a sustainable and resilient maritime sector by leveraging ADB’s strength in mobilising resources across its global network and GCMD’s expertise in addressing operational complexities through real-world pilot projects.

SRMF aims to enable a future-ready maritime transport system through these focus areas: invest in resilient port infrastructure, accelerate adoption of alternative fuels, close financing gaps, and foster regional policy harmonisation.

By lowering fuel consumption, EETs are considered a “no-regrets approach” to reducing emissions in the maritime sector. Yet, EET adoption faces significant hurdles primarily arising from the challenges to accurately quantify fuel savings, which translates to an uncertainty in return on investment.

To address this gap, GCMD is currently developing and testing methodologies to validate fuel savings through the deployment of onboard sensor installations. By providing clear attribution of fuel savings to specific technologies, GCMD aims to implement Pay-As-You-Save (PAYS), a financing model proven in other sectors. Under PAYS, upfront investments in EETs can be repaid over time, with payments directly tied to verified fuel savings. This approach aligns stakeholder interests and fosters risk-and-reward sharing.

ADB and GCMD are partnering to combine their complementary strengths—exchanging knowledge from GCMD’s pilots and ADB’s financing expertise—to address barriers in green financing. By grounding green financing in verified emissions reduction data, the collaboration aims to build investor confidence, unlock capital for bankable, scalable decarbonisation solutions, and accelerate the widespread adoption of EETs in the maritime sector.

Professor Lynn Loo, CEO of GCMD, said: “At this critical juncture, the IMO’s announcement of a global emissions pricing mechanism sends the clearest signal yet that urgent action is required—not only to advance decarbonisation, but also to safeguard the long-term commercial viability of shipowners. 

“Energy efficiency technologies (EETs) can play a vital role by reducing fuel consumption, thereby lowering the penalties shipowners will face under IMO’s framework. We believe that the Pay-As-You-Save (PAYS) model can uniquely accelerate and scale the adoption of these critical solutions. 

“In this context, we value the opportunity to leverage ADB’s extensive global network to drive meaningful progress, particularly in unlocking financing to support sustainable growth of the maritime industry.”

Mr. Hideaki Iwasaki, Director General, Sectors Department 1, ADB, said: “ADB’s partnership with the Global Centre for Maritime Decarbonisation reflects our shared commitment to unlocking private capital and accelerating the deployment of clean technologies in the maritime sector.

“Through the Sustainable and Resilient Maritime Initiative and associated new funding arrangements being developed, we are supporting our client countries to modernise ports, strengthen regional trade connectivity, and de-risk investments that drive greener, more resilient supply chains. Together with GCMD, we aim to bridge the gap between innovation and implementation.”
