Ethanol

Our ambition is to contribute to the transformation of the offshore energy industry through innovative, efficient and sustainable solutions, accelerating the transition to a cleaner, more efficient energy mix aligned with global decarbonization targets.

CO₂ is naturally captured from the atmosphere during the growth of sugarcane or corn;
Ethanol is sulfur-free;
Brazil has an ideal climate for production;
Logistics infrastructure is already developed;
Easy shipping and storage;
Lower technological challenges than those posed by the alternatives currently available;
Low toxicity, particularly when compared with its direct competitor, methanol;
Competitive prices;
High availability of degraded land in Brazil that can be converted to new plantations, avoiding deforestation;
Growth in the production of ethanol from corn grown during the soybean off-season, optimizing land use;
Second-generation ethanol can increase production efficiency, as it is produced from sugarcane residues;
Growth in ethanol production worldwide (e.g., India and the USA).

Marine Fuels Today and in the Future


Fuel type	Low Sulfur Fuel Oil @ 20°C	Liquefied Natural Gas @ -162°C	Ethanol @ 20°C	Methanol @ 20°C	Ammonia @ -33°C	Liquid Hydrogen @ -253°C	Compressed Hydrogen 350 bar
Key considerations	Standard tank arrangement	Cryogenic system	Lower toxicity compared to methanol  Flexible tank arrangement	Mildly toxic Flexible tank arrangement	Toxic Corrosive	Highly flammable Cryogenic system	High pressure Multiple tanks arrangement Highly flammable
Regulation readiness
Volumetric energy equivalent	1x	1.6x	1.7x	2.3x	2.9x	4.3x	11.7x
Tank hold space compartment volume	1x	1.7x–2.4x*	1.3x	1.7x	3.9x	7.3x	19.5x

Gross tank estimations based on Wärtsilä experience considering inspection spaces needed around the tanks. Cylindrical tanks only considered for LNG, if stored in a prismatic tank, the LNG gross tank size factor is more favorable than for methanol.
* Membrane tanks: 1.7x; type C tanks: 2.4x.

“Our ambition is to contribute to the transformation of the offshore energy industry through innovative, efficient and sustainable solutions, accelerating the transition to a cleaner, more efficient energy mix aligned with global decarbonization targets.”

By betting on ethanol as an alternative for the future of offshore shipping, Oceanity is embracing a solution with strong ties to Brazil and the potential to reposition the maritime industry from a more sustainable and innovative perspective.

More than a technological choice, this is a vision for the future: building a fleet prepared to lead and drive a new generation of more efficient and sustainable offshore operations.
