emissions during navigation and at berth. The ambitious requirements for ships to reduce emissions starting in 2025 will help drive the uptake of alternative fuels in shipping, as well as help ensure the use of shore side electricity (SSE).


Green Corridors are taking off


As international cooperation is needed, the maritime industry is setting up ‘green corridors’ with coalitions of other ports, container carriers, forwarders, fuel suppliers and other stakeholders in order to make supply chains sustainable.


In late February, Global Spatial Technology Solutions (GSTS) said it will collaborate with the Montreal Port Authority (MPA) in providing a Green Shipping Corridor capability using their Artificial Intelligence platform.


In March 2023, the United States of America, the Republic of Fiji, the Republic of Panama and the Pacific Blue Shipping Partnership announced their intent to engage in technical cooperation to help facilitate the establishment of green shipping corridors.


On March 15th, California and Japan signed a letter of intent with the aim to establish green shipping corridors.


Global Maritime Forum had said that a new consortium will explore the options for developing a maritime green corridor for the zero-emission shipping of iron ore between South Africa and Europe.


On March 23rd, a Memorandum of Understanding (MoU) was signed by DFDS ferry operator, the Port of Dover, the Port of Boulogne Calais and the Port of Dunkerque to work together to decarbonize maritime trade in the Dover Strait.


The conflict over alternate fuel is ongoing


There is currently a competition between Korean and Chinese shipbuilders about which is taking more shipbuilding orders, as methanol-powered ships are rapidly emerging as next-generation eco- friendly ships. In March 2023, ONE announced that it has ordered ten new container vessels to be ready for methanol and ammonia, outfitted

with a bow cover and other energy- saving technologies.


During the 2023 GREEN4SEA Athens Forum, experts had the opportunity to share their perspectives on the different alternative options that exist. When it comes to ammonia, ’’technological maturity at the present is at the baby-teething phase since there are no engines commercially available to burn ammonia’’, noted Dr. John Kokarakis, Technical Director South East Europe, Black Sea & Adriatic Zone at Bureau Veritas. Although ammonia is promulgated as one of the fuels in the future multi-fuel society, a major stumbling block is the IGC Code of IMO which prevents the carriage and utilization of toxic fuels, he said. It appears that ammonia will be more utilized as a carrier of hydrogen in a future hydrogen ecosystem.


According to Grieg Star, green ammonia is seen as one of many possible fuels for shipping in the future. ‘’Currently, it seems more viable for multifuel-ready new buildings than for retrofitting current ships. We need changes on a political and regulatory level to make the change for the existing world fleet.’’, said Managing Director of Grieg Star,


Atle Sommer. Ammonia, hydrogen, ethane and Dimethyl Ether (DME) are among the “alternative” marine fuels which may need future regulatory work, IMO said in March following a recent assessment which is the result of a regulatory mapping exercise conducted by Low Carbon GIA, with inputs and contributions from ICS.


The shipping industry is increasingly turning to a basket of technologies that can harvest an abundant, zero-emissions energy source that is available globally today, i.e. the wind. ‘’Wind propulsion has been extensively researched, tested, discussed, piloted and by some, dismissed throughout the last decade’’, noted Mr. Gavin Allwright, Secretary General, International Windship Association (IWSA) during the GREEN4SEA event. ‘’2023 is a pivotal year for shipping, as we head into IMO discussions at MEPC80, and we have an opportunity to tackle multiple challenges at once, setting ambitious decarbonisation targets that also address the need for a just transition and build the foundations for a resilient, sustainable maritime sector.’’ added Mr. Andrew Stephens, Executive Director, Sustainable Shipping Initiative.
