The Yacht Club de Monaco hosted a conference focusing on 'Alternative fuels and advanced yachting technology' as part of the Monaco Energy Boat Challenge week. The event aimed to propel the yachting sector towards a sustainable future, aligning with the Monaco Capital of Advanced Yachting initiative. Discussions at the conference delved into the utilization of alternative fuels in yachting, with methanol emerging as a promising option due to its high energy density and ease of storage compared to hydrogen. Industry experts from Lürssen highlighted methanol's advantages and the ongoing engine developments tailored for this fuel. Furthermore, the potential inclusion of nuclear energy in yachts was explored, with considerations on effectiveness, integration challenges, and the overall sustainability impact. Insights from Feadship suggested that while nuclear reactors could provide uninterrupted power, their effectiveness may be limited as most yachts operate seasonally, making on-shore reactors a more viable option. Another crucial aspect discussed was the importance of measuring emissions and defining life cycles in the yachting industry. The Sea Index, in collaboration with RINA, introduced a novel methodology to calculate CO2 emissions based on fuel types and bunkering practices. This methodology aims to provide a comprehensive analysis taking into account various factors such as biofuels and their concentrations, contributing to a more sustainable approach. Collaboration among stakeholders including yacht builders, technical partners, owners, and regulatory authorities was emphasized throughout the event. The need for confidence in alternative fuels, infrastructure development for fuel availability in ports, and swift regulatory actions were highlighted to drive the adoption of sustainable practices in the yachting industry. The event showcased a collective effort towards embracing advanced technologies and alternative fuels to shape a greener future for yachting.
