Making boating sustainable

About Fossil Free Marine

Fossil Free Marine develops infrastructure solutions that enable the transition to fossil free and sustainable boating, both biofuels and fast charging for electric boats. Our product platform allows distribution of the latest modern biofuels (e.g HVO100/ XTL renewable diesel and in the near future gasoline alternatives, such as Neste’s BioGasoline), future electrofuels (e.g e-Methanol) and other sustainable options (such as alcylate) in marine environments, while maintaining sustainable and financially viable operations. Within the same scalable product architecture we also develop innovative technical solutions for fast charging of fully electric and hybrid boats (BEV/PHEV), specifically designed for demanding marine environments. We are firm believers that sustainable boating is within our reach, and that we have the solutions to enable the necessary transition in our product portfolio and roadmap. Welcome aboard sustainable boating!

Fossil Free Marine has received a substantial Swedish Government investment grant from “The Climate Leap” (KlimatKlivet), for local climate investments, for incremental costs for distributing renewable fuels for our first installation, outside Stockholm.
