An environmentally friendly ship propulsion system and a method for propelling a ship. The ship propulsion system comprises an osmosis chamber (1), a pressure relief unit (2) and a desalination unit, the osmosis chamber (1) comprising a high salinity region (11) and a low salinity region (12) separated from one another by an osmotic membrane (13). The pressure relief unit (2) having at least one pressure-motion converter connected to the high-salinity region (11) of the osmosis chamber (1) via high-pressure line (21). The desalination unit is suitable for producing salt or at least high-salinity water and fresh water or at least low-salinity water. A fresh water pipe connecting the desalination unit with the low salinity area (12) of the osmosis chamber (1) and a salt water supply (14) is controllably connected to the high salinity area (11) of the osmosis chamber (1).
