Alternative fuels for shipping

sails

There is no doubt that alternative fuels will play a crucial role in the transition of international shipping. To decarbonise, the industry will need to adopt zero-carbon technologies. For us at EDF Europe, alternative fuels are one of the main topics related to shipping. We have been looking at different fuels and assessing opportunities their implementation would bring to countries and their economies.

Sailing on Solar: Could green ammonia decarbonise international shipping?

In May 2019, we published a report Sailing on Solar analysing the application of green ammonia (i.e. ammonia made with renewable energy) in international shipping. The report, prepared by global sustainability consultancy Ricardo Energy and Environment, identified green ammonia as one of the most promising zero-carbon shipping fuel options. Green ammonia can offer a climate solution if it can be produced at scale using abundant untapped renewable energy resources without increasing fossil fuel use, and can be used in modified shipping engines and hydrogen fuel cells. Moreover, the authors concluded that wider adoption of such a fuel can unleash trillions of dollars of investment opportunities in sustainable industrial infrastructure, particularly in developing countries. 

The paper also analysed issues around the potential supply of green ammonia – such as the construction of production plants and infrastructure – as well as the demand from the vessels themselves, including fuel transport and engine compatibility. The study demonstrates that countries with untapped renewable energy potential could benefit by establishing a green ammonia supply chain for the marine sector.

This is shown in a case study of Morocco where green ammonia production could be developed using its abundant renewable energy capacity. In addition, Morocco’s large commercial ports near important shipping lanes make the country well-suited to foster a green ammonia industry. This capacity can be used to attract investment in Morocco for renewable energy and green ammonia that otherwise would not happen.

More information about the report can be found in this blog, alternatively the full report is available for download.

Webinar

At the end of July 2019, we partnered with Ricardo once again to make the Sailing on Solar paper accessible to a wider audience. We ran two webinars presenting the main findings of the report as well as policy solutions for decarbonisation of the shipping sector which you can watch by clicking below. 

At the end of July 2019, we partnered once again with Ricardo to present the conclusion of our Sailing on Solar report to a wider audience in the form of a webinar. 

How about other fuels?

Alternative fuels will be needed not only to meet (and hopefully exceed) the International Maritime Organisation's target to reduce greenhouse gas emissions by at least 50% by 2050 compared to 2008 levels. They will play also an important role in helping the industry to meet criteria for the 2020 sulphur cap. Green ammonia is certainly not the only solution for zero-carbon shipping and its share in the future fuel mix will depend on a wider range of factors. We have analysed other low or zero carbon fuel options for the shipping industry and created a simple overview of the main findings here.
