The Lloyd’s Register Maritime Decarbonisation Hub and the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping will partner on a new project to develop guidance around the safe use of ammonia as a fuel
The project’s aim is to understand and guide the safe use of ammonia as a fuel on board ships. ‘Green’ ammonia can be produced from renewable power by electrolysis of H2O, ultimately making it a zero-carbon fuel. However, the fuel’s extreme toxicity makes it critical to address safety issues to mitigate risks to people, assets and the environment.
Part of this will include developing a mature and detailed understanding of risks and safety concerns, which will be assessed through a quantitative risk assessment methodology in phase one of the project.
This will 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, and 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 fuelled by ammonia.
The Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping will manage the project which is expected to run throughout 2021. The centre’s head of onboard vessel solutions, Claus Winter Graugaard said “In the eagerness to decarbonise the shipping sector, proper risk management is critical and safety must not become an afterthought. This project will provide matured understanding of safety risks enabling industry guidance towards design and 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 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.”
Other industry partners involved in the project include AP Moller-Maersk, MAN Energy Solutions, Mitsubishi Heavy Industries, NYK Line and Total.
