At Riviera’s 27th ITS Convention, methanol emerged as a leading candidate for cleaner marine fuels, highlighted by the launch of the Methatug at the Port of Antwerp-Bruges as part of the Fastwater project. The Methatug, powered by dual-fuel engines capable of storing and combusting methanol, is one of several pilot projects exploring different propulsion technologies and fuels, including the world's first hydrogen-powered tugboat and a battery-electric tug. The Methanol Institute reports a surge in methanol fuel bunkering on merchant ships and the construction of port infrastructure to support methanol usage. Plans for green methanol production plants are underway, with a forecasted increase in annual production by 2028. While methanol gains momentum, hydrogen also shows promise as a marine fuel, but regulatory challenges persist. The Zero Emissions Ship Technology Association anticipates a shift towards hydrogen but stresses the need for updated regulations to ensure safety. Additionally, hydrogen storage poses a significant challenge, with ammonia being explored as a potential solution. Amidst these developments, the industry is preparing for a future driven by cleaner marine fuels, with hydrogen and ammonia emerging as key contenders alongside methanol.
