What Is HVO fuel? The cleaner diesel alternative explained

What does HVO stand for?

HVO is a renewable diesel alternative made from 100% waste-derived materials like used cooking oils and animal fats. It’s a paraffinic fuel produced through a specialised hydrotreatment process, rather than esterification like FAME biodiesel.

This means HVO burns cleaner and performs better in engines compared to traditional biodiesel.

Is HVO fuel a type of biodiesel?

Yes and no. HVO fuel is often lumped in with biodiesel, but it differs in both production and performance. Unlike FAME (Fatty Acid Methyl Ester) biodiesel, HVO is free from oxygen, giving it superior storage stability and cold-weather performance.

It’s chemically very similar to fossil diesel, meaning it's a ‘drop-in’ replacement for diesel engines with no modification required.

The benefits of HVO fuel

• Lower emissions
  HVO reduces net greenhouse gas emissions by up to 90% compared to conventional diesel. It also produces significantly less NOx and particulate matter - helping improve local air quality.
• Reliable performance
  Thanks to its clean-burning profile and excellent cold weather resistance (down to -32°C), HVO diesel is ideal for off-grid power, construction sites, transport and backup generators.
• Drop-in compatibility
  HVO meets EN 15940 fuel standards and is suitable for use in existing diesel engines without upgrades or blending.
• Extended shelf life
  Unlike FAME biodiesel, HVO has better oxidation stability, which means it won’t degrade as quickly during storage.
• Made from waste
  It’s derived from 100% waste feedstocks, used cooking oils, residues and animal fats, making it both sustainable and circular.

Any downsides?

• Higher cost
  HVO fuel typically costs more per litre than standard diesel. However, this may be offset by fuel efficiency gains, reduced maintenance needs and carbon reduction benefits.
• Limited availability
  While availability is growing across the UK and Europe, supply may still be limited in certain regions.
• Feedstock scrutiny
  Though made from waste products, some experts argue that the increasing demand for HVO could eventually pressure global feedstock markets.

HVO fuel FAQs

Is HVO fuel better than diesel?
In many ways, yes. HVO burns cleaner, stores longer and emits fewer harmful pollutants than conventional diesel.

Can I switch to HVO without modifying my equipment?
Yes. HVO diesel is a drop-in replacement compatible with most diesel-powered machinery, generators and vehicles.

What is HVO fuel made from?
It’s made from 100% renewable waste - primarily used cooking oils, animal fats and other sustainable feedstocks.

How much does HVO cost compared to diesel?
While prices vary, HVO fuel typically costs more than standard diesel per litre. However, long-term environmental and operational benefits can balance this out.

If you’re looking to reduce emissions without overhauling your entire fleet or fuel system, HVO fuel offers a practical and accessible solution. We’re helping businesses take those steps.
