The yachting industry saw groundbreaking advancements in sustainability with the launch of Feadship's Project 821 and Sanlorenzo's Almax, both embracing hydrogen-powered technologies. Project 821, a 119-meter zero-diesel superyacht, is equipped with hydrogen fuel cells that produce electricity and water vapor as by-products. This innovation allows the yacht to operate its hotel systems emission-free, leading towards a 'net zero' commitment by 2030. Similarly, Sanlorenzo's Almax introduces a modular reformer-fuel cell system that converts green methanol into hydrogen to power the yacht's hotel systems without storing hydrogen onboard. This system enables the vessel to generate up to 100kW of electricity, significantly reducing diesel consumption during anchor times. These initiatives mark a shift towards cleaner energy sources in the yachting sector, focusing on sustainability and environmental friendliness. By pioneering these hydrogen technologies, both Feadship and Sanlorenzo are paving the way for a greener future in luxury yachting.
