The article discusses various hydrogen tugboat projects, highlighting the challenges and solutions regarding onboard storage capacities. Projects range from carrying 36 kg of hydrogen to a substantial 4,350 kg, emphasizing the scalability of hydrogen technology for powering larger vessels. The Topeka prototype vessel, part of the EU-funded HySHIP project, is set to become the first zero-emissions vessel running on liquid green hydrogen, showcasing advancements in maritime fuel. Industry experts stress the importance of evaluating sustainability options carefully for tugboat operations, with a mention of biofuel usage as an interim measure towards reducing emissions. While the Asian towage market faces price sensitivity limiting investments in R&D, there is a government-driven energy transition towards carbon-neutral fuels and electrification, aligning with goals of achieving net-zero emissions by 2050. Despite challenges, including the complexity of bunkering options, there is a collective acknowledgment among industry professionals of the necessity to transition towards alternative fuels like hydrogen despite the current dominance of diesel engines in terms of performance and efficiency.
