Hydrotreated Vegetable Oil (HVO) is one of the cleanest and most effective renewable diesel alternatives available today. As businesses and individuals look to reduce their environmental impact, HVO is quickly becoming a preferred fuel choice across the UK and Europe.
What Does “HVO” Mean?
HVO stands for Hydrotreated Vegetable Oil. It is a 100% renewable fuel produced from sustainable waste materials such as used cooking oil, animal fats and other approved waste feedstocks.
These materials are refined using a specialist hydrotreatment process, resulting in a high-quality renewable diesel that meets strict European fuel standards. Unlike traditional biodiesel, HVO is highly stable and can be stored for long periods — often up to 10 years — without degrading.
How Is HVO Fuel Made?
HVO is created by processing renewable waste feedstocks with hydrogen at high temperatures and pressures. This hydrotreatment removes impurities and converts the raw materials into clean, paraffinic hydrocarbons.
The result is a fuel that closely matches the chemical structure of fossil diesel, but with significantly lower emissions and improved performance characteristics. This advanced production process is what sets HVO apart from first-generation biodiesel fuels.
HVO Fuel vs Traditional Diesel
HVO is often described as a drop-in replacement for diesel, meaning it can be used in existing diesel engines without modification. It performs very similarly to fossil diesel but offers major environmental advantages.
Unlike biodiesel blends (such as FAME), HVO does not suffer from blending limits, cold-weather issues or reduced storage stability. This makes it suitable for a wide range of applications, from transport and construction to generators and heating systems.
Key Benefits of HVO Fuel
HVO offers a combination of environmental, operational and practical benefits:
✅ Reduced emissions
HVO can reduce lifecycle greenhouse gas emissions by up to 90% compared to conventional diesel, depending on the feedstock used.
✅ Drop-in fuel
No engine modifications or infrastructure changes are required. HVO can be used as a direct replacement for diesel.
✅ Clean and efficient combustion
HVO burns more cleanly than fossil diesel, producing lower levels of particulates, carbon monoxide and nitrogen oxides.
✅ Excellent cold-weather performance
Thanks to its low cloud point, HVO remains effective in very cold temperatures, making it reliable year-round.
✅ Long storage life
HVO is highly stable and resistant to oxidation, allowing it to be stored for long periods without deterioration.
✅ Biodegradable and low toxicity
In the event of a spill, HVO breaks down naturally and poses less environmental risk than fossil fuels.
Are There Any Limitations?
While HVO offers significant advantages, there are a few considerations to be aware of:
❗ Higher cost
HVO is typically more expensive than standard diesel, although this can be offset by environmental benefits and sustainability targets.
❗ Supply availability
UK supply is improving but may still be more limited than conventional fuels in some regions.
❗ Not zero-emission
HVO is a low-carbon fuel, not a zero-emission solution. It is best viewed as a transition fuel toward fully zero-emission technologies.
Final Thoughts
HVO fuel provides a practical, immediate way to reduce carbon emissions without changing vehicles, machinery or infrastructure. With its strong performance, long storage life and significant environmental benefits, HVO is an ideal solution for businesses and individuals looking to take meaningful action toward sustainability today.
