The project Zemships (Zero Emissions Ships) developed a 100 person hydrogen-power passenger ship, power-assisted by an electric motor that gets its electricity from a fuel cell. The first boat operates on the Alster in Hamburg since 2008. The keel laying at the SSB shipyard in Oortkaten was on 4 December 2007.
