We are LNG pioneers

In 2018, we delivered AIDAnova, the first ocean liner to run exclusively on liquefied natural gas (LNG). It’s currently the cleanest cruise ship in the world. The low-emission fuel fully prevents the release of particulate matter and sulphur oxides and significantly reduces the emission of nitrogen oxides and carbon dioxide. MEYER WERFT was working on this solution with its partners for ten years. AIDAnova has become the first cruise ship to be awarded the “Blauer Engel” environmental seal by the German government. The development of the LNG drive system has consolidated our position as the technological leader in the construction of cruise liners, and it’s also a huge incentive for us to continue our research. Our objective is to build a zero-emission cruise ship with alternative and renewable fuels – we’re putting all our passion and courage into the development of new ideas.

Engines of the future

In 2021, MEYER WERFT will start testing fuel cells on AIDAnova as the next milestone in the development of climate-neutral shipping solutions. Fuel cells are seen as the technology of the future. The concept is as simple as it is ingenious – hydrogen plus oxygen generates electricity and heat. Hydrogen is obtained from methanol, which can be produced sustainably from renewable energy sources. This means fuel cells operate without any harmful emissions – they only produce water vapour. The technology also reduces noise and vibration, which is an important requirement for cruise ship operations.

Fuel cells are being trialled on an ocean liner for the first time with the aim of developing new and long-lasting fuel cells. Our initial tests have revealed that we could achieve a service life of over 35,000 operating hours. The research project is also investigating the on-board integration of fuel cells. An additional focus is on the economic and environmental aspects.

MEYER WERFT is working on the project with various specialists, including Lürssen Werft, the German Aerospace Centre and AIDA Cruises, represented by Carnival Maritime. The project is being funded by the Federal Ministry of Transport and Digital Infrastructure as part of the National Innovation Programme for Hydrogen and Fuel Cell Technology.

Energy efficiency on board

The specialist engineers and technicians at MEYER WERFT are making lots of tiny adjustments to sensors, heat recovery and insulation features to further boost the efficiency of our on-board systems. As all the energy required on board is generated by the ship’s engines, a lot of fuel can be saved through energy-efficient operations to protect the environment and reduce our running costs.
