Maritime updates: modeling engine room fuel leaks, testing a new fuel supply system

Julian Atchison June 04, 2023

ABS has used computational fluid dynamics to model ammonia dispersion patterns in a ship’s engine room, with the aim of producing a fast, real-time response system for ammonia leaks. In Japan, a fuel supply system for large-scale, low-speed, two-stroke marine engines is undergoing final verification testing. Mitsubishi Shipbuilding aims to become a key technology provider of such systems, and in the ammonia maritime fuel space.

Ammonia supply chain between the Middle East & Japan takes shape

Julian Atchison May 10, 2023

Mitsui & Co., INPEX and Japanese government agency JOGMEC will partner with ADNOC to verify the emissions intensity of ammonia produced at a new project in al-Ruwais, UAE. The final methodology is likely to reflect the definition of clean ammonia currently being developed in Japan. Shipments of CCU-based ammonia have arrived in Japan & India in recent weeks from SABIC in Saudi Arabia, further highlighting the potential of Middle East supply chains.

Key shipping stakeholders see a multi-fuel future: new survey results

Julian Atchison May 08, 2023

A recent survey reveals how shipping industry leaders see the maritime fuel transition progressing. With conventional ship engines set to remain the preferred technology until at least 2050, almost all the survey respondents saw their fleets running on a mix of fuels by that date. Although methanol & ammonia are likely to be adopted at scale, respondents do not currently see any of the new fuels emerging as an industry standard, with key choices ahead for shipping companies, fuel producers, bunker providers and industry regulators.

Safety and the marine ammonia engine

Julian Atchison

Explore the critical topic of engine room safety, and what design considerations would be needed on a future, ammonia-fueled vessel. What learnings can we apply from running prototype engines? What lessons can be learned from current ammonia-handling industries like refrigeration? And what training will be needed to build confidence in seafarers?

Scrap “green” and “blue” hydrogen, use emissions intensity instead: new IEA report

Oscar Pearce May 05, 2023

The International Energy Agency has proposed a new taxonomy for hydrogen definitions based on emissions intensity, moving away from color labels. In Towards hydrogen definitions based on their emissions intensity, the IEA proposes a set of nine distinct, technology-neutral emissions intensity bands. The report also advocates for an international approach to ensure interoperability between certification schemes, and suggests that a mutual recognition approach based on the IPHE’s emissions methodology is the best way forward.

UK government releases plans for low-carbon hydrogen certification scheme

Oscar Pearce April 18, 2023

The UK government has released a consultation paper outlining its current position on several certification dilemmas, as it works towards launching a fully functioning low-carbon hydrogen certification scheme before 2025. The paper grapples with challenging design choices including chain of custody and scheme participation while emphasising the importance of international collaboration and interoperability.

New pricing service announced for low-carbon ammonia

Julian Atchison April 12, 2023

Argus Media is the latest organisation to launch a pricing service for low-carbon ammonia, following on from CRU and S&P Global Commodity Insights. The services build on existing methodologies, assumptions and trade routes for fossil-based ammonia.

Current certification gaps hindering development of a global market: new IRENA report

Oscar Pearce April 05, 2023

IRENA and RMI’s new report Creating a global hydrogen market: Certification to enable trade concludes that there are significant gaps and conflicts in current certification schemes. Inconsistent labelling thresholds, accounting boundaries, and production pathways are the main areas of concern. The report offers several recommendations to support the harmonisation of certification frameworks, warning that schemes cannot continue to develop in a “patchwork” manner.

NoGAPS vessel project enters next phase

Julian Atchison April 03, 2023

The second phase of the NoGAPS project is well underway. Led by the Maersk Mc-Kinney Møller Center for Zero Carbon Shipping, a detailed plan for the design, operation and business case for the future MS NoGAPS vessel will be developed. Construction and delivery is expected in 2024-25. Also in Scandinavia, Viridis Bulk Carriers has been awarded AiP from Bureau Veritas for its ammonia-fueled, short-sea, bulk carrier design.

Mitigating emissions risks from ammonia-powered vessels

Julian Atchison March 20, 2023

Technology solutions to manage emissions from ammonia-powered internal combustion engines will be commercially available on a similar timeline to the engines themselves, a new report from the Mærsk Mc-Kinney Møller Center concludes. Although the authors are confident ammonia combustion emissions (including the potent greenhouse molecule N₂O) will be successfully minimised, key gaps include a lack of industry-wide emissions thresholds and a poor understanding of the well-to-tank emissions of ammonia fuel, particularly CCS-based ammonia.
