In a groundbreaking development, a consortium in Scotland, led by Forth Ports, has successfully launched a world-first green hydrogen-based shore-power pilot project to provide electricity for a tugboat in the Port of Leith, Edinburgh. This initiative, part of the Clean Ports of the Future project, involves partners like Targe Towing, Plus Zero Power, Logan Energy, and Waterwhelm. The project utilizes green hydrogen generated from processed wastewater as a sustainable energy source to power a tugboat, replacing traditional diesel generators. The water for hydrogen production is purified through innovative water treatment technology at the Seafield water treatment plant. The project achieved its first green hydrogen production in January 2025, with a tugboat successfully connected to the shore-power unit in March. The commercial director of Targe Towing, Alasdair Smith, hailed this achievement as a significant step towards cleaner and more sustainable maritime operations. The tugboat, Targe's azimuth tractor tug Balmerino, built by Sanmar Shipyards, became the first vessel to be powered by green hydrogen through a quayside generator, signaling a new era for eco-friendly port operations. This milestone not only underscores the commitment to net-zero operations by Forth Ports but also positions them among a select group of ports worldwide generating green hydrogen. The project is part of the UK Department for Transport's initiative to reduce emissions in the domestic maritime sector, with a focus on developing decarbonization technologies. This pioneering project sets a benchmark for future sustainable maritime initiatives and showcases the potential of green hydrogen in revolutionizing the shipping industry.
