Stena Germanica was built by Astilleros Españoles shipyard in Puerto Real, Spain.
To accommodate the extra traffic the Stena Hollandica was sent to the Lloyd Werft yard in Bremerhaven in March 2007 for lengthening.
The Stena Germanica is the first major marine vessel to run on recycled methanol after a conversion in 2015 in Poland.
For reliability purposes, the common rail engine can still run on the marine gas oil as backup.
Operation on methanol is expected to reduce SOx emissions by 99%, NOx by 60%, carbon dioxide by 25% and particulate matter by 95%.
