Australian shipyard Austal and Swedish ferry operator Gotlandsbolaget have signed a letter of intent to develop and build a high-speed catamaran capable of operating on hydrogen or other green alternative fuels. The ferry is expected to operate on routes connecting the island of Gotland in the Baltic Sea with the Swedish mainland. 

The project concerns the development of a design of a 130-meter long high-speed catamaran. The announcement did not clarify how the catamaran would be powered, noting that the vessel would be capable of operating on different fossil-free fuels, including hydrogen.  

The intention is for a construction order to be placed for the Horizon X by 2025. The company expects the Horizon X or a larger alternative design, Horizon, to enter into service by 2030. The company has a target of achieving net zero emissions on crossings to Gotland by 2045.
