Liquefied synthetic natural gas (GNS) from the maritime world. The 10.53 gross ton ElbBlue was supplied with this neutral fuel in the German port of Brunsbuttel, near Hamburg, for a trip to Saint Petersburg, Russia, and a second refueling is planned when it returns to Germany before continue towards Rotterdam.

REintegrate and European Energy will establish a new Danish facility to produce the approximately 10,000 tonnes of carbon-neutral electric methanol that the first Maersk vessel with the capacity to operate on green electronic methanol will consume annually. Maersk will work closely with REintegrate and European Energy in the development of the facility.

The report, financed by the World Bank, does not recommend the use of LNG as a marine fuel or the support of investments in LNG infrastructure, not only because it is not compatible in the long term with a goal of zero emissions but also denies its advantages as transition fuel.

The consulting firm Sphera (formerly thinkstep) updates its report on the emissions of ships powered by LNG and confirms the advantages of LNG as a marine fuel in reducing polluting emissions and analysis concludes that, in addition, LNG can contribute "without a doubt" to the GHG reduction objectives of the International Maritime Organization (IMO).

The Canadian company Ballard Power Systems signs a Memorandum of Understanding with Global Energy Ventures (GEV), provider of integrated compressed maritime transport solutions for the transport of energy to regional markets based in Australia for the development of a new ship with fuel cell. fuel, called C-H2 Ship, designed to carry compressed green hydrogen.

The objective of the CHEK project (deCarbonising sHipping by Enabling Key technology symbiosis on real vessel concept designs), is to reduce emissions from maritime transport through the integrated use of forms of energy and low-carbon technologies. These include the use of hydrogen fuel, wind power, electric batteries, heat recovery, air lubrication, and new antifouling technology. Development work on how to design and operate ships is also included.
