Sustainable Marine Fuels

Renewable Diesel Fuel

Also referred to as Hydrotreated Vegetable Oil (HVO), renewable diesel fuel is a drop-in replacement that performs just like fossil diesel and can be used without any modifications to the engine or boat fuel system and blended at any ratio. Classified as a drop-in renewable diesel fuel, these advanced biofuels meet industry specifications in compliance with OEM standards. Unlike biodiesel, renewable diesel fuel offers reliable cold weather performance and is free of sulfur, oxygen and aromatic compounds. It can reduce greenhouse gas emissions by up to 75% relative to conventional fossil-derived diesel fuel.

Partially Renewable Gasoline

Renewable feedstocks such as corn, sugar cane, or other advanced cellulosic derived sugars are fermented to create alcohol. The biologically derived alcohol, such as ethanol or biobutanol, is then used as a building block to create an ethanol-free gasoline blend stock. When mixed with conventional gasoline, these renewable fuels reduce the quantity of fossil fuels required for each gallon of finished gasoline. It can reduce greenhouse gas emissions up to 30% more than E10 at the same renewable content.

Biobutanol

Biobutanol is a high energy content alcohol produced in a fermentation process similar to beer and wine. Unlike ethanol, biobutanol does not phase-separate in the presence of water, making it a very stable fuel for recreational boats and engines. Biobutanol lowers evaporative emissions, and unlike ethanol, doesn’t require a pollution waiver from EPA summertime gasoline vapor pressure standards. Biobutanol blended at 16.1% by volume has double the renewable energy compared to 10% ethanol. Biobutanol can reduce greenhouse emissions by up to 30% relative to convention fossil-derived gasoline.

Liquid Drop-In e-Fuels

Electricity-based eFuels and biogenic synthetic fuels are a step in achieving carbon neutrality. eFuels are produced by combining captured carbon from the atmosphere with green hydrogen in a synthesis process known as Fisher-Tropsch. These fuels result in a carbon-neutral liquid fuel that is a 1:1 replacement for gasoline and diesel. Significant investment is ongoing in the further development of these game-changing fuels.
