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.

Quantifying the environmental impacts of ammonia at sea

Sofia Furstenberg Stott March 09, 2023

In our latest episode of Maritime Ammonia Insights, we explored the findings of a new, landmark environmental study: Ammonia at Sea. Speakers representing the report’s co-authors joined us to discuss the results, what further work is required and how the report is being incorporated into policy discussions at the IMO.

Technology status: ammonia production from electrolysis-based hydrogen

Kevin Rouwenhorst January 31, 2023

Electrolysis-based ammonia production peaked worldwide around 1970, before the economies of scale and cheap gas feedstock led to its decline. With decarbonization and climate-neutral industrial processes now a critical priority, electrolysis-based ammonia production has re-emerged as a long-term solution. From a base of 10,000 tonnes per year worldwide production in 2020, as much as 100 million tonnes per year of electrolysis-based ammonia could be produced by the end of this decade, driven by a dramatic roll-out of renewable energy generation and installed electrolyzer capacity.

How to build a green shipping corridor

Sofia Furstenberg Stott December 18, 2022

COP27 saw an exciting number of green shipping corridor announcements. But the question remains: how do we actually build them? Earlier this year, the Maersk McKinney Møller Centre for Zero Carbon Shipping launched a Feasibility Phase Blueprint, setting out some key assessment criteria to consider. At the recent annual AEA conference in Phoenix, we took a group of sixty participants through the criteria, asking how and where the ammonia sector should engage.
