    Maritime actors push on with overcoming ammonia fuel safety concerns

    Conor Furstenberg StottSofia Furstenberg Stott July 18, 2022

    Two recent reports (one from Bureau Veritas & Total, the other from the Together in Safety consortium) illustrate just how seriously the maritime industry is pursuing low carbon ammonia fuel. While progress in the maritime ammonia space is impressive, safety risks are widely-acknowledged and work remains to be done.

    Both reports identify key hazards facing adoption of ammonia as a maritime fuel, and echo points heard before in the development of methanol & LNG as maritime fuels: high-risk hazards currently exist that must be eliminated, mitigated or controlled. But Together in Safety concludes the way forward will be via collaboration & shared responsibility - something we’re already seeing in the multiple high-profile safety studies and consortia working around the globe. Thankfully, the willingness of significant maritime players to engage on ammonia and the momentum for change are both high.

    GCMD & DNV: Pioneering Ammonia Bunkering Safety in Singapore

    Sofia Furstenberg Stott June 17, 2022

    Our latest episode of Maritime Ammonia Insights revealed key details about the Ammonia Bunkering Safety Study currently being undertaken in Singapore. The study is led by the Global Center for Maritime Decarbonisation (GCMD), with DNV acting as a consulting partner. Lau Wei Jie (GCMD) took us through the high-profile lineup of study partners, and explained how the study aims to develop an extensive technical guideline for ammonia bunkering, similar to TR 56 (which covers LNG bunkering). Dr. Imran Ibrahim (DNV Maritime Advisory), then explained the technical scope of the study, how pilot project sites will be selected, and how the study partners are using previous work from Rotterdam and Oslo to hone their approach. Our audience was eager to understand how this work in Singapore might be applied elsewhere, and keenly awaits the results, which are due for public release in February 2023.

    Ammonia infrastructure: panel wrap-up from the 2020 Ammonia Energy Conference

    Julian Atchison January 22, 2021

    Infrastructure is key to realising the full potential of ammonia energy, enabling new markets and expanding the existing ones. By 2050 the hydrogen (and by extension, ammonia) market could be 20 times larger than it is today. What future possibilities are there to expand global ammonia production (currently 180 million tonnes per year) or trade volumes across the world’s oceans (currently 18 million tonnes per year)? On November 18, 2020, the Ammonia Energy Association (AEA) hosted a panel discussion moderated by Daniel Morris from KBR, as well as panel members Anthony Teo from DNV GL, Oliver Hatfield from Argus Media, and Michael Goff from Black & Veatch as part of the recent Ammonia Energy Conference. The panel’s insights from a number of different perspectives - market analytics, ship building and operating, as well as pipeline engineering - demonstrated ammonia's potential to become a low- or zero-carbon fuel of choice for the future. Current infrastructure can be adapted, new infrastructure can be built and operated cheaply, and lessons from previous fuel transitions can be taken on board to make the uptake of ammonia energy as smooth as possible.

    Ammonia as Alternative Maritime fuel

    Anthony Teo

    Global shipping will by 2050 need to reduce the GHG emissions by 50% compared to the 2008 baseline, according to one of the targets set by the IMO, as well as a goal of being GHG neutral by the end of the century. The adoption of carbon neutral fuels will be a key enabler to achieve this goal. This presentation will consider these issues and suggest a process and pathway to overcome regulatory barriers, safety, and infrastructure for ammonia that needs to be addressed to facilitate the use of ammonia as a fuel in shipping.

    Picking bunker winners: the mono-fuel / dual-fuel duel

    Trevor Brown September 24, 2020

    This week, DNV GL published its annual Maritime Forecast to 2050, concluding that “e-ammonia, blue ammonia and bio-methanol are the most promising carbon-neutral fuels in the long run.” DNV GL’s assumptions that determine this long run, however, suggest a significant mid-term reliance on fossil LNG. This risks locking the industry into a long-term emissions trajectory incompatible with the IMO’s 2050 GHG targets, in part because of significant fuel supply and infrastructure investments. These investments could become more ‘sticky’ than expected. A host of alternative opinions have been published in the days before and after DNV GL published its report. These suggest that, for ammonia, the long run could begin this decade. Among others, MAN ES has announced that its ammonia engine will be available for retrofits by 2025.

    Maritime Ammonia: ready for demonstration

    Trevor Brown May 07, 2020

    At least four major maritime ammonia projects have been announced in the last few weeks, each of which aims to demonstrate an ammonia-fueled vessel operating at sea. In Norway, Color Fantasy, the world's largest RORO cruise liner, will pilot ammonia fuel. Across the broader Nordic region, the Global Maritime Forum has launched NoGAPS, a major consortium that aims to deploy "the world's first ammonia powered deep sea vessel" by 2025. In Japan, a new industry consortium has launched that goes beyond on-board ship technology to include "owning and operating the ships, supplying ammonia fuel and developing ammonia supply facilities." And the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), which published its roadmap last month, aims to demonstrate ammonia fuel on "an actual ship from 2028" — specifically, a 80,000 dwt ammonia-fueled bulk carrier.

    Maritime fuel mix could be 25% ammonia by 2050

    Trevor Brown September 20, 2019

    DNV GL published its annual Energy Transition Outlook last week, which includes a dedicated analysis of the shipping industry in its Maritime Forecast to 2050. According to DNV GL, the IMO's 2050 emission reduction targets can be met through innovative ship design, using ammonia as an alternative fuel. Widespread commercial adoption of ammonia fuel would begin in 2037; ammonia would the dominant fuel choice for new builds by 2042; and ammonia would represent 25% of the maritime fuel mix by 2050. This represents new demand for roughly 120 million tons per year of green ammonia by 2050. This outcome greatly depends on how maritime regulations are developed in the coming years, but it would see ammonia-fueled ships represent almost 100% of new vessels (by fuel consumption) from 2044 onwards.

    Maritime Industry Targets Ammonia Fuel to Decarbonize Shipping

    Trevor Brown October 25, 2018

    In the last 12 months ... The International Maritime Organization issued its Initial GHG Strategy, committing the global shipping industry to emission reductions that cannot be achieved with carbon-based fuels. This single action is the regulatory trigger that unleashes a three-decade transition to carbon-free liquid fuels like ammonia. The target date for this 50% reduction in emissions is 2050 but, given the long economic life of ocean vessels, the transition must begin immediately.

    DNV GL predicts carbon-neutral fuels, including ammonia, to surpass oil for shipping by 2050

    Trevor Brown September 14, 2018

    This week, DNV GL published its annual Energy Transition Outlook, providing a long-term forecast for global energy production and consumption, and including a dedicated report describing its Maritime Forecast to 2050. This is the first forecast from a major classification society explicitly to evaluate ammonia as a maritime fuel. By 2050, DNV GL predicts that 39% of the global shipping energy mix will consist of "carbon-neutral fuels," a category that include ammonia, hydrogen, biofuels, and other fuels produced from electricity. By 2050, these fuels will therefore have gained greater market share than oil, LNG, and battery-electric. If ammonia succeeds as the carbon-neutral fuel of choice in the shipping sector, this new demand will be roughly equivalent to 200 million tons of ammonia per year, more than today's total global production.
