Fuel cell testing project continues


Testing of new fuel cell technology is scheduled to continue until the end of October.



Two months since the 'Undine' left the German port of Bremerhaven with Wärtsilä's WFC20 fuel cell unit installed, testing of this new technology is scheduled to continue until October 31, when the vessel arrives in the USA, via Sweden and the UK.

Finland's Wärtsilä said the 'unique' power unit is the first of its kind in the world, and will, during the test period, provide auxiliary power to the vessel while producing close to zero emissions.

"This project is an important step towards more environmentally sound shipping and cleaner seaborne transportation," Wärtsilä said in a statement.

The fuel cell unit, which has a nominal output of 20 kW, is based on planar solid oxide fuel cell technology (SOFC), and fuelled with methanol. Methanol is particularly suited for fuelling the WFC20 since it can be easily reformed to a composition suitable for the unit. Methanol can be produced from natural gas, or from renewable raw materials such as gasificated biomass. Methanol is a commonly used liquid in the oil and process industries, and is available in all major harbours.

Installation of the WFC20 fuel cell unit onboard the 'Undine' is the result of a joint project by the international METHAPU consortium. The participants in the consortium are Wärtsilä, Wallenius Marine, Lloyd's Register, Det Norske Veritas, and the University of Genoa, each of whom is globally active in the field of fuel cell system integration, sustainable shipping, classification work or environmental assessment. The project has been funded with EUR 1 million from the European Union, and is part of the European Community Framework Programme (FP6).

The principal aim of the METHAPU project has been to validate and demonstrate new technologies for global shipping that can reduce the environmental impact of vessels. In addition, a further major aim is to establish the necessary international regulations for the use of methanol onboard commercial vessels, and to allow the use of methanol as a marine fuel.

"The development of sustainable sea transportation is a long term target and one that Wallenius Marine is strongly committed to. The METHAPU project supports this vision, not only through developing sustainable fuel cell technology for commercial transportation applications, but also by providing the opportunity to utilize a new renewable marine fuel. Furthermore, Wärtsilä's deep expertise in SOFC fuel cell technology provides us with a solid platform from which to gain useful experience for the future," said Per Croner, President, Wallenius Marine.

Essential part of Wärtsilä's strategy

Fuel cells are considered to be one of the most exciting energy technologies for the future. In addition to methanol, Wärtsilä's fuel cells can efficiently utilize various gases as fuel and produce almost zero nitrogen oxide (NOx), sulphur oxide (SOx) and particulate emissions, all of which are harmful to the environment. It is expected, therefore, that fuel cell technology will also offer significant benefits to the shipping industry, where international emission regulations are becoming increasingly stringent.

The development of fuel cell technology is a part of Wärtsilä's long-term product development, aimed at supplementing the company's product portfolio. The development of environmentally friendly and sustainable energy production technologies is an essential part of Wärtsilä's strategy.

In 2008, Wärtsilä delivered a unique fuel cell unit, producing electricity and heating to the Vaasa Housing Fair site in Finland. The WFC20 unit, used in this project, runs on methane rich gas originating from a nearby landfill, and was developed and is operated by Wärtsilä.
