AP Moller-Maersk, Fleet Management Ltd, Keppel Offshore & Marine, Maersk Mc-Kinney Moller Center for Zero Carbon Shipping, Sumitomo Corporation and Yara International have entered into a MoU to establish a comprehensive and competitive supply chain for the provision of green ammonia ship-to-ship bunkering at the Port of Singapore.

Emitting zero CO2 when combusted, ammonia has long been considered as one of the most promising alternative marine fuels to reduce GHG emissions within the shipping industry, which is in line with the IMO strategy to reduce CO2 emission. In particular, green ammonia possesses great potential as it is produced from only renewable electricity, water and air with no CO2 emission.

The Study aims to cover the entire end-to-end supply chain of ammonia bunkering, which includes the development of a cost-effective green ammonia supply chain, design of ammonia bunkering vessels, as well as related supply chain infrastructure. Relevant government agencies and experts in Singapore will be engaged in working towards the standardisation of safe operation and regulations. The study will assess the supply of ammonia including potential synergies with Liquefied Petroleum Gas (LPG) as a starting point. Considering the comparable requirements for mild refrigerated storage, vessels or barges initially designed for LPG can also handle brown (i.e. conventional), blue (produced from matural gas with carbon capture) and green ammonia.

Maersk will provide input specific to container vessels and will work on development of safe and reliable bunkering procedures for ammonia. Fleet Management will work on the development of safe and reliable operating bunkering procedures for the alternative marine fuels from manning service provider's point of view. Keppel O&M will develop and design the new build ammonia bunkering vessel and ammonia-ready LPG bunkering vessel4 and lead in the coordination with relevant authorities in Singapore to establish port regulations and operational guidelines. Maersk Mc-Kinney Moller Center for Zero Carbon Shipping will map all safety related topics in an ammonia maritime technology roadmap, the outcome of the bunkering study being integrated in a techno-economic model including detailed understanding of end-to-end cost and Life Cycle Analysis. Sumitomo Corporation will structure, integrate and promote the end-to-end supply chain of green/blue/brown ammonia and LPG as the alternative marine fuels, which includes supply, transportation, storage and bunkering. Yara International will lead in the feasibility evaluation of the supply of green/blue/brown ammonia to Singapore.

Morten Bo Christiansen, VP and Head of Decarbonisation, AP Moller-Maersk, said: “Alongside Methanol, at AP Moller-Maersk we see green ammonia as an important future fuel for the decarbonisation of our fleet. A dual fuel Ammonia engine is currently under development, but for green ammonia to fuel our vessels in the future we also have supply, infrastructure and safety related challenges to solve, not least when it comes to bunkering operations. We are pleased to work with renowned companies in this field to pave the way for Ammonia as a future fuel to decarbonise global shipping. ”

Kishore Rajvanshy, MD Fleet Management, said: “We are very pleased to support the development of the green transition pathway for our industry. We participate with our technical expertise across ship types to provide holistic solutions to sustainability, and alongside other alternative fuels such as methanol we feel ammonia will play a significant role.”

Chris Ong, CEO of Keppel Offshore & Marine, said: “There are multiple routes to the decarbonisation of the marine industry and we are pleased to be able to leverage our expertise in engineering and bunkering to spearhead the development of cleaner marine fuels such as ammonia. This includes the design of ammonia bunkering and ammonia-powered vessels, as well as developing the value chain necessary for the adoption of ammonia. This is in line with Keppel’s Vision 2030, which includes seizing opportunities in new energy.”

Bo Cerup-Simonsen, CEO of Maersk Mc-Kinney Moller Center for Zero Carbon Shipping, said: “It is key to understand the complete life cycle and safety implications of any future fuel across the supply chain. This project will address gaps in infrastructure and regulation and bring forward the solutions needed for safe operations and bunkering of ammonia in ports. We truly look forward to the collaboration and to contribute to this important work."

"With this MoU, we embark on our ambition to build the world's first Ship-to-Ship ammonia bunkering base, which highlight our commitment to offer our customers the best available and technologically proven solution to reduce the emission footprint from maritime transport," said Hajime Mori, Executive officer, Sumitomo Corporation.

Magnus Ankarstrand, EVP Yara Clean Ammonia, said: “Ammonia as energy carrier is an enabler of the energy transition and we recognize the need for value chain collaboration to make zero emission shipping by using ammonia as a fuel a reality.”
