What is hvo diesel

Last updated: April 1, 2026

Quick Answer: HVO diesel, or Hydrotreated Vegetable Oil, is a renewable diesel fuel made by chemically processing plant-based oils. It can be used as a drop-in replacement for conventional diesel fuel in most diesel engines without modifications.

Key Facts

What is HVO Diesel

HVO diesel, officially known as Hydrotreated Vegetable Oil, is a sustainable biofuel produced through the hydrotreating of plant-based oils and animal fats. The hydrotreating process involves treating raw vegetable oils with hydrogen under heat and pressure in the presence of catalysts. This chemical transformation removes impurities and converts the oils into a high-quality diesel fuel that meets strict automotive fuel standards. HVO represents a major advancement in renewable fuel technology.

Production Process

The production of HVO begins with collecting feedstock such as rapeseed oil, palm oil, soy oil, used cooking oil, or animal fat residues. These raw materials undergo the hydrotreating process in industrial refineries. The process removes oxygen, impurities, and unstable compounds, resulting in a paraffinic fuel with superior properties compared to conventional diesel. The hydrotreating process requires specialized equipment and technical expertise, but the resulting fuel meets all technical specifications for diesel engines.

Environmental Benefits

HVO diesel offers significant environmental advantages over conventional diesel fuel. It reduces lifecycle greenhouse gas emissions by up to 90% depending on the feedstock used. The use of waste and residue materials as feedstock minimizes the environmental impact compared to virgin vegetable oils. HVO also reduces air pollutants including particulates, nitrogen oxides, and hydrocarbons when burned. These environmental benefits have made HVO increasingly popular in Europe and other regions committed to reducing transportation emissions.

Compatibility and Performance

One major advantage of HVO diesel is its compatibility with existing diesel engines and infrastructure. HVO can be used as a complete drop-in replacement (HVO100) without engine modifications, or blended with conventional diesel in any proportion. The fuel performs well in cold weather, often better than conventional diesel, with improved cold flow properties. It has excellent lubricity and stability, extending engine component life and storage stability. Most modern diesel engines, from passenger cars to heavy trucks, can safely operate on HVO fuel.

Market Growth and Regulations

The HVO market has experienced rapid growth, particularly in Northern Europe. Sweden, Norway, and Finland have implemented policies encouraging HVO adoption. The European Union has set ambitious sustainability targets that favor renewable fuels like HVO. Growing environmental awareness and government mandates are driving increased investment in HVO production capacity. As more countries implement renewable fuel requirements, HVO is expected to become increasingly available and affordable at fuel stations worldwide.

Related Questions

Can I mix HVO diesel with regular diesel?

Yes, HVO can be blended with conventional diesel in any ratio without engine modifications. Many fuel suppliers offer blended fuel with a percentage of HVO to improve environmental performance while maintaining full compatibility with standard diesel engines.

Is HVO more expensive than regular diesel?

HVO typically costs slightly more than conventional diesel, though prices vary by region and market conditions. However, the improved fuel efficiency and reduced maintenance costs can offset the price difference over time.

What vehicles can use HVO diesel?

Most modern diesel vehicles can use HVO without modification, including passenger cars, SUVs, trucks, and industrial equipment. It's particularly suitable for vehicles requiring low-emission fuel and is mandatory for many European commercial fleets.
