It was fitted with a vertical axis wind turbine to generate electricity for the electrolysis of water to fill the hydrogen storage tanks.
The total storage and transportation capacity was 1194 cubic metres (42200 cu ft).
It was stationed in the German Bight near Heligoland (where the most wind is), and was to dock in Bremerhaven, where the hydrogen produced would be delivered to the market.
However, the project appears to have been a subsidy fraud: The ship never made trips in its planned function.
The converter that was to produce the hydrogen was delivered by the manufacturer in good faith, but later taken back because the bill was not paid.
