TT-Line has confirmed an order for a second battery-hybrid LNG newbuild, acting as a sister vessel to its first Green Ship 2.0 ordered in late 2025. Set to be built by China Merchants Jinling Shipyard for a 2030 delivery, the vessels feature a 5.5 to 10 MWh expandable battery system and LNG propulsion to enable zero-emission port stays and future fully electric operations across the Baltic Sea.
LÜBECK-TRAVEMÜNDE | July 10, 2026 – German ferry operator TT-Line has reinforced its commitment to sustainable maritime transport by confirming an order for a second next-generation battery-hybrid LNG newbuild. Acting as a sister vessel to the first Green Ship 2.0 announced in late 2025, the new order marks another major milestone in the company’s long-term fleet renewal and decarbonization strategy on the Baltic Sea.
Advanced Shipyard Collaboration and Timeline
Following successful cooperation on previous builds, the second vessel will likewise be constructed by China Merchants Jinling Shipyard in Nanjing, one of the world’s premier ferry shipbuilders. The first vessel of the class is scheduled to enter service on the Baltic Sea before the summer of 2030.
Building upon the strong customer feedback and operational success of current Green Ships NILS HOLGERSSON and PETER PAN, the Green Ships 2.0 have been engineered to deliver a substantial increase in transport capacity while optimizing efficiency, environmental stewardship, and passenger comfort.
Enhanced Capacity and Dimensions:
- Freight Capacity: 5,400 lane meters per vessel, meeting growing demand across Sweden, Germany, Poland, and Lithuania.
- Passenger Capacity: Up to 1,000 persons on board (930 listed in technical metrics).
- Passenger Cabins: 300 modern cabins, including specialized designs tailored for families, couples, and truck drivers.
Cutting-Edge LNG-Hybrid and Battery Propulsion
At the heart of the Green Ship 2.0 design is a sophisticated LNG-hybrid propulsion system integrated with a large-scale LFP battery energy storage system ranging from 5.5 MWh to 10 MWh.
Key technical and environmental features include:
- Zero-Emission Port Operations: The battery system enables fully electric, silent maneuvering and emission-free power during port stays.
- Scalable Architecture: Dedicated, fully equipped additional battery rooms and future-ready electrical infrastructure allow for expanded electrification over the vessels’ operational lifespans.
- Optimized Efficiency: Advanced Power-Take-In and Power-Take-Out technologies lower peak load requirements and provide high operational flexibility.
- High-Capacity Shore Power: Upgraded shore connections facilitate rapid, high-capacity battery charging during port calls.
Next-Generation Onboard Experience
Passengers traveling across the Baltic will experience a completely redesigned interior layout handled by interior designers Ocean Architects (Germany), based on naval architecture by OSK Design (Denmark).
Amenities include enlarged sun decks featuring a wellness area with a sauna and jacuzzi, children’s play facilities, a sun deck bar, enhanced family-friendly lounges, dedicated pet areas, and modernized lounge concepts.
Executive Perspectives
Highlighting the strategic importance of the expansion, Bernhard Termühlen, CEO of TT-Line, stated:
“The order of a second Green Ship 2.0 demonstrates TT-Line’s long-term commitment to provide efficient and state of the art transport solutions in the Baltic Sea between Sweden, Germany, Poland and Lithuania.”
Andreas Schärli, COO of TT-Line, added:
“By adding a second Green Ship 2.0, we are accelerating the transformation of our fleet. The combination of LNG propulsion, large-scale battery technology and advanced shore power capabilities provides the flexibility needed to meet both today’s and tomorrow’s environmental challenges. With expandable battery capacity, both vessels are designed for fully electric operation in the future.”

About TT-Line
TT-Line offers the densest route network for direct services to southern Sweden. Operating nine ships with up to 24 departures daily, TT-Line connects the German Baltic Sea ports of Travemünde and Rostock, the Polish port of Świnoujście, and the Lithuanian port city of Klaipėda with Trelleborg and Karlshamn in southern Sweden. The shipping company is the market leader in passenger and freight transport between Germany and Sweden, a connection that has been established since 1962.
TT-Line ships are operated in accordance with IMO requirements introduced in 2015 to further reduce ship emissions. Five of the nine ferries run on environmentally friendly marine fuel with a maximum sulfur content of 0.1%. In addition, TT-Line has installed flue gas desulfurization systems on the ferries Tinker Bell, Akka, Nils Dacke, and Marco Polo. This not only significantly reduces sulfur emissions but also lowers the particle content in exhaust gases. Streamlined hull designs and fuel-efficient speed management further improve the CO₂ footprint. TT-Line’s technology and environmental management have already received multiple awards.
With its Green Ships Nils Holgersson and Peter Pan, TT-Line is the first shipping company and a pioneer in the southern Baltic Sea to use LNG (Liquefied Natural Gas) as fuel, enabling significant emission reductions. Our Green Ships can operate on both LNG and Bio-LNG, making us a pioneer in sustainable shipping. Bio-LNG is a carbon-neutral, renewable fuel produced from waste such as organic household waste, sewage sludge, manure, and agricultural residues. By adding Bio-LNG to the booking, we offer our customers the option of CO₂-free travel.
In December 2025, TT-Line signed a contract to build a new Green RoPax ferry 2.0, approximately 240 meters long, with capacity for around 1,000 passengers. The vessel will feature advanced LNG-hybrid propulsion, enhanced passenger comfort, improved cabins, and spacious outdoor areas. Building on the success of LNG-powered ferries Nils Holgersson and Peter Pan, this next-generation ship will further improve operational and environmental efficiency. The project continues TT-Line’s partnership with China Merchants Jinling Shipyard and reinforces the company’s commitment to sustainable mobility and zero-emission technologies, including bio-LNG and shore-power-fed battery systems.
