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.

The search for alternative fuels with the lowest carbon footprint

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

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.

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.
