The Port of Antwerp-Bruges in Belgium is making strides in transforming its operations to be more environmentally friendly. By aiming to be climate neutral by 2050, the port authority is actively working on greening its service fleet, which includes tugs, service vessels, and dredgers. Peter Degroote, the Nautical Operations Manager, emphasizes the importance of operating the fleet efficiently to reduce energy consumption. One of the key highlights is the introduction of the Hydrotug 1, the world's first hydrogen-powered tugboat. This vessel, built by CMB.TECH, features dual-fuel hydrogen/diesel engines, ensuring operational reliability even in the event of hydrogen-related issues. The positive experiences from sea trials of the Hydrotug 1 reflect the success of this innovative approach. Additionally, the port is exploring other low-emission propulsion systems, such as hybrid methanol/electric tugs, to further enhance its green energy initiatives. While challenges exist in terms of regulations and training for new propulsion technologies, the port is committed to overcoming these hurdles to gather crucial data for future planning. The multi-fuel approach, focusing on multiple eco-friendly fuel options like methanol and hydrogen, demonstrates the forward-thinking strategy of the port authority in embracing sustainable practices. Overall, the Port of Antwerp-Bruges' dedication to pioneering green energy solutions in maritime operations signifies a positive step towards achieving environmental sustainability and reducing carbon emissions in the region.
