The company said this is part of a demonstration project using Japanese biofuel company Euglena’s brand "Susteo". The product uses used cooking oil (UCO) and other materials as feedstocks.

The HVO 100 is a class II petroleum product and can be transported by conventional fuel supply vessels, the company said.

It can be used as a drop-in fuel, without needing any modifications to existing marine diesel engines and fuel supply infrastructure.

Kamei said it will use this demonstration project to build a stable supply system for the product and get operational know-how.

It will also identify challenges and conduct technical verification for full-scale deployment in the future.
