Swedish fuel company Preem has signed up to a year-long contract with gas supplier Gasum of Finland to take a blend of liquefied biogas (LBG) and LNG to fuel two tankers it has on charter.

Gasum sales director Jacob Granqvist believes this is the first time a company has taken contracted volumes of LBG over a term period for marine bunkering, outside of the pilots that have been done on using the fuel.
