Questions & answers

Hydrotreated vegetable oil (HVO) is a renewable paraffinic (diesel) fuel. It is derived from used cooking oils, residue animal fats from food processing, tall oil, and non-food grade crops.

HVO, a new generation of bio-based diesel, has been treated with hydrogen in order to meet the European EN15940 standard for ‘Paraffinic Diesel Fuel from Hydrotreatment’. This more complex process produces a cleaner fuel, without the drawbacks of traditional, or first generation, biodiesel.

Paraffinic diesel fuels are specified in EN15940 and have higher cetane numbers and lower density than conventional diesel fuels (EN590). HVO and Bio to Liquid (BTL) are renewable paraffinic (diesel) fuels, whereas Gas to Liquid (GTL) is an alternative fossil paraffinic (diesel) fuel. HVO is a clear, colorless, odorless liquid.

The use of renewable (HVO and BTL) fuels will give a substantial decrease (up to 90%) of fossil CO2 emissions. Featuring the low sulfur and aromatics associated with paraffinic fuels, HVO burns more cleanly than first generation biodiesel or mineral diesel. Due to its good oxidation stability, it is not prone to bacterial growth.

HVO and diesel are similar, chemically and physically. The key differences to traditional diesel include approximately 7% less fuel density, less sulfur (5mg/kg vs 10mg/kg), no aromatics (0% vs 5%) and a higher cetane value, indicating a more complete combustion process.
