A new and innovative hydrogen fuel cell-powered and electric liquid waste collection vessel is set to transform waste management at the Port of Klaipéda in Lithuania starting in late 2025. The vessel, constructed by Baltic Workboats Ltd and Western Baltija Shipbuilding, boasts a length of 42 meters and width of 10 meters, with a substantial capacity of 400 m3. This tanker, costing €11.7M, marks Lithuania's pioneering venture into hydrogen-powered and electric maritime technology. It will be equipped with 2,000 kWh of batteries and a cutting-edge hydrogen fuel-cell system, allowing it to operate continuously for up to 36 hours in the port waters without emissions. Baltic Workboats will oversee the installation of the electric propulsion, battery packs, power management, and navigation systems, along with outfitting accommodation spaces. The project, receiving support from the EU's European Regional Development Fund, highlights a significant step towards sustainable and environmentally friendly maritime practices in the region.
