IEA: ammonia key to decarbonising shipping by 2050
Julian Atchison October 03, 2023
With international shipping activity to more than double by 2050, the IEA forecasts that ammonia’s share of final energy consumption in the industry will rise to 44% in 2050, with a suite of other low-carbon fuels to play smaller roles. Lloyd’s Register & OCI HyFuels have also forecast that ammonia (and particularly electrolytic ammonia) will become the most significant fuel in the maritime sector by 2050.

New report released on environmental hazards of ammonia spills
Julian Atchison December 13, 2022
Ricardo, Lloyd’s Register and the Environmental Defense Fund have used extensive modeling to assess the environmental impacts of large-scale ammonia spills in a variety of maritime scenarios. The study concludes that large-scale spills will have a high impact on certain environmental settings, and in particular fish species. The report also indicates that ammonia is less likely to spread & persist in the environment compared to a spill of conventional maritime fuel, and in some cases will pose less of a threat to certain species. More considerations need to be worked through, including health risks to a ship’s crew.

Green Maritime Corridors - A catalyst for transition to green shipping fuels
Conor Furstenberg Stott March 01, 2022
The ports of Los Angeles and Shanghai have announced the intention to create a green shipping corridor across the Pacific Ocean. The ambition is for ships trading between these ports to run on alternative low greenhouse gas emission fuels. Ammonia stands among the options as such an alternative.
There is a clear willingness from key players at the LA end of this trans-Pacific shipping corridor to embrace alternative fuel solutions and work together to unlock a suite of zero emissions technologies, albeit limited to an onshore focus for now. Shifting focus onto the water - where ammonia maritime fuel will undoubtedly play a critical role - is the logical next step.

Ammonia as a fuel – building the business case
The successful substitution of current fossil-based fuels by zero-carbon energy sources is dependent on a combination of policy / regulation, investment and commercial business model development and fuel / technology development that will evolve over the coming years. The evolution of both the energy system and the shipping system that is needed, and associated timescales of development, investment and asset life, means that there are steps that need to be initiated now, and work carried out throughout this decade, even though the transition may not be completed for a couple of decades. This presentation looks at the Technology readiness, investment…

The maritime sector's ammonia learning curve: moving from scenario analysis to product development
Trevor Brown October 25, 2019
ANNUAL REVIEW 2019: The maritime industry is learning about ammonia fast. It is searching for a new bunker fuel, and ammonia is one of the few options that can realistically deliver a 50% reduction in the sector's GHG emissions by 2050. The IMO declared this target in April 2018 and, in last year's Annual Review, I wrote about all the reports that were published demonstrating that ammonia could deliver this outcome. In the last 12 months, by contrast, we have moved quickly beyond analysis and into engineering design, technology testing, and product development.

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.

Bunker Ammonia: new report quantifies ammonia as "the most competitive" fuel for zero-emission maritime vessels in 2030
Trevor Brown December 15, 2017
This week, Lloyd's Register published the most significant comparative assessment so far of ammonia's potential as a zero-emission maritime fuel. The new report compares ammonia, used in either internal combustion engines (ICE) or fuel cells, to other low-carbon technologies, including hydrogen, batteries, and biofuels, estimating costs for 2030. It concludes that, of all the sustainable, available options, ammonia "appears the most competitive."

Bunker Ammonia: carbon-free liquid fuel for ships
Trevor Brown March 23, 2017
The shipping industry is beginning to evaluate ammonia as a potential "bunker fuel," a carbon-free alternative to the heavy fuel oil (HFO) used in maritime transport. International trade associations are leading the effort to decarbonize the sector, in alignment with targets set by the Paris Climate Agreement. Their immediate challenge is simple to state but hard to solve: "ambitious CO2 reduction objectives will only be achievable with alternative marine fuels which do not yet exist." In the long-term, however researchers recognize that "fuel cell-powered ships are likely to dominate, drawing their energy from fuels such as hydrogen and ammonia."
