“The production of green ammonia is a key component of the decarbonization plans for international shipping. While the largest 17,000 ships are unlikely to find economic value in using hydrogen-derived green fuels, a very significant portion of the world fleet may find green ammonia to be a viable pathway to zero emissions.

“The decarbonization of other difficult to abate sectors such as chemical and steel manufacture as well as aviation will also require the manufacture of a substantial amount of these green e-fuels, Core Power said.

The concept

“Our concept design is for an offshore facility partnering advanced nuclear power with an offshore ammonia production facility, which will create green ammonia from abundant seawater and air. No emissions would come from the plant,” says Dr Rory Megginson, CORE POWER’s Director of Analytics.

Core Power said its modeling showed that with current technology it is possible to produce one million tonnes of ammonia per year using 1.2 GW of electric power, on each floating production platform, reducing to 0.9 GW by 2050. This is the equivalent of 440,000 tonnes of very low sulphur fuel oil (VLFSO) and it would allow the decarbonization of a considerable number of vessels, the company said.

The flexible nature of these systems will mean it will also be possible to provide a mixture of electricity, hydrogen, and ammonia for other applications, including chemical manufacturing and aviation, Core Power said Dr. Megginson says: “The production of green ammonia at sea using advanced nuclear power would be superior to both productions from renewables and non-marine atomic systems because atomic power has the highest capacity factor of any power generation method – whereas intermittent renewables, notably wind and solar, have the lowest. This reliability and dispatchability makes advanced atomic the ideal power source for e-fuel production.”

Moving the reactors to sea will allow for a substantial reduction in costs due to the lack of a need for expensive civil engineering as well as opening the possibility of shipyard construction, Core Power said.

“The production of Molten Salt Reactor technology is modular by design rather than the historical ‘first of a kind reactor,’ that has kept nuclear generation prices elevated up until now. Offshore advanced atomic power shows the best results at the lowest cost for large scale, secure, and truly green ammonia production,” the company said.

In his speech, Soren Toft explained MSC’s views on the status of decarbonization in the container shipping sector, summarized how the company is approaching this challenge and commented on how everyone must move forward together in collaboration to tackle climate change.

As shipping volumes have grown over the years, so have the environmental emissions produced as a by-product of delivering goods around the world. Container lines such as MSC must continue to do their part to help mitigate the impact of climate change while continuing to operate responsibly in meeting the ever-increasing demand for global trade, Toft said, “It is critical that our priority this year is not only to respond to the huge demand we are experiencing in the very complex, congested markets that emerged amid COVID, but also to ensure that we do not decouple this from our efforts to decarbonize.”

Toft said collaboration is key to achieving the decarbonization goals set out by the shipping industry, and noted MSC already fosters industry-wide, as well as cross-sector collaboration to enable the massive required investments. While the company continues to invest in low-carbon technologies and explore different fuel options, carriers in general continue to struggle from a lack of solutions available at scale, the CEO said.

With the total cost of decarbonizing shipping estimated into the trillions of dollars, carriers must make expensive capital decisions that will live on for decades. Urgent investment and a better understanding of how business and society will share the cost burden is also required, Toft said.

Soft emphasized that “the transition to a low-carbon economy requires broad collective action and productive partnerships with our stakeholders across and beyond shipping.”

“By cooperating and collaborating with others, we will capitalize and build on the interdependencies between ocean-going and inland logistics as well as other sectors providing fuels, distribution systems and infrastructure,” he concluded.
