The Klaipeda State Seaport Authority has announced the launch of “Lithuania’s first hydrogen and electricity-powered ship”, marking a step towards sustainable maritime operations.

The €12m ($12.5m) project is a collaborative effort between the Port Authority, West Baltic Shipyard, and Baltic Workboats.

Klaipeda Port has a policy requiring ships to dispose of their waste responsibly when arriving and before leaving the port.

The vessel is designed to collect and treat waste including storm water, sewage, sludge and garbage, from other ships within the port.

It will feature “special” tanks and a contemporary rainwater purification system, enabling the processed water to be channelled into municipal wastewater facilities.

The vessel has a capacity for managing up to 400m³ of liquid waste.

Measuring 42m in length and 10m in width, the ship features a power system comprising dual electric motors powered by 2,000kWh batteries and a hydrogen fuel cell system.

The vessel is capable of up to 36 hours of continuous operation without the need for recharging.

Construction of the ship began in June last year, with a keel-laying ceremony at the West Baltic Shipyard.

The ship's hull is now complete, with essential components such as piping and insulation installed.

The vessel’s launch into the water paves way for the fitting of engine room equipment, wheelhouse interior, electrical systems, and the hydrogen fuel system.

Klaipeda State Seaport Authority director general Algis Latakas said: “We have not only launched a tanker, but also a new approach to port operations – cleaner, smarter and more environmentally friendly.

“This first ever hydrogen and electricity-powered ship is not only an innovative technological solution, but also an important step in strengthening Lithuania’s image as a modern maritime nation.”
