Master's Thesis: Ensuring HVO Quality Across the Supply Chain

VAROPreem sources, stores, transports, produces, distributes, and markets renewable liquid fuels. Throughout the value chain, we

work to ensure that our products comply with regulatory requirements and meet the highest quality standards.

One of our most important renewable products is HVO (Hydrotreated Vegetable Oil), a paraffinic diesel fuel used as an alternative

to conventional fossil diesel. Although HVO has been on the market for many years, there is still limited knowledge about how the

fuel behaves throughout the supply chain and under different contamination scenarios.

HVO (Hydrotreated Vegetable Oil) plays a key role in the transition towards more sustainable transportation and is one of the most

important renewable alternatives to fossil diesel. Maintaining product quality throughout the supply chain requires a solid

understanding of how HVO behaves during storage, transportation, and distribution.

In practice, HVO may come into contact with other fuels and petroleum products at various stages of the logistics chain. Even

small amounts of contamination can influence fuel properties and product quality. As the share of renewable fuels continues to

grow, understanding these interactions becomes increasingly important for ensuring both product performance and regulatory

compliance.

The purpose of this thesis is to improve our understanding of the physical and chemical properties of HVO and investigate how the

fuel is affected by contact with other fuels and petroleum products throughout the supply chain.

The project aims to identify factors that influence product quality and increase understanding of potential risks associated with

the storage, transportation, and distribution of HVO.
