Fuel cell manufacturer Cellkraft has successfully completed a 162 kilometer voyage with their fuel cell powered boat:

A boat powered by a fuel cell system has made a trip from Stockholm to Öregrund in the north of the Stockholm archipelago. The trip took place Sunday-Monday 17-18 October. The fuel cell system was based on the Cellkraft S-1000 fuel cell and the Genesis 20L-D reformer. The test was part of project performed by Cellkraft, financed by the Swedish Defence Material Administration. The purpose has been to demonstrate a robust and efficient fuel cell system to generate electric power from methanol. The journey had a total length of 86,5 nautical miles (162 km). It was performed in two non-stop day trips in a small boat with a two men crew. The average speed was 4,6 knots. 13 litres of methanol was consumed. The energy content is equal to 5 litres of diesel.

The boat was propelled by an electric outboard engine that got electric power from a fuel cell. The fuel cell was fed with hydrogen from a reformer that continuously converts methanol to hydrogen. The test is likely the first fuel cell powered boat trip in Sweden and one of the longest in the world. The energy consumption was 0,06 diesel equivalent per nautical mile.
