In the United Kingdom, the conversation around cleaner, greener fuels has never been more urgent. With carbon reduction targets, rising fuel prices, and growing awareness of sustainability, many households and businesses are searching for reliable alternatives to traditional diesel and heating oil. One such alternative gaining significant attention is HVO fuel — a modern, renewable replacement that promises efficiency without compromise.
This comprehensive guide will explore what HVO fuel is, its benefits, uses, and compatibility, helping you understand why it’s becoming a leading choice for British homes, transport fleets, and industries.
What Is HVO Fuel?
HVO stands for Hydrotreated Vegetable Oil, a synthetic, renewable diesel made from sustainable feedstocks such as used cooking oils, animal fats, and vegetable oils. It’s not the same as standard biodiesel; HVO is a next-generation fuel produced through a hydrogenation process, not esterification (the method used for FAME biodiesel).
Through hydrogenation, impurities like oxygen are removed, resulting in a high-quality, paraffinic fuel that mirrors the performance of fossil diesel but with a much lower environmental footprint.
In simpler terms, HVO Fuel is a drop-in renewable diesel that can often be used in existing diesel engines or heating systems without modification.
How Is HVO Fuel Made?
The production of HVO fuel involves a sophisticated refining process called hydrotreatment. Here’s how it works:
- Feedstock Collection: Renewable and waste oils (like used cooking oil or animal fat) are collected.
- Pre-Treatment: The feedstocks are cleaned to remove impurities.
- Hydrotreating Process: Hydrogen is added under high temperature and pressure to remove oxygen and other elements.
- Isomerisation: The molecules are rearranged to enhance cold flow properties and improve stability.
- Final Refining: The resulting fuel is clear, odourless, and ready for direct use in diesel engines or oil-fired heating systems.
This process gives HVO its chemical purity and performance consistency, making it one of the most advanced renewable fuels available today.
Why HVO Fuel Is Gaining Popularity in the UK
Across the UK, from Cornwall to the Highlands, both homeowners and businesses are exploring HVO as a low-carbon alternative. The transition is partly driven by the government’s Net Zero 2050 target and initiatives encouraging renewable energy adoption.
Moreover, major fuel suppliers are expanding their HVO availability, allowing easier access for logistics firms, construction companies, farmers, and even domestic users looking to cut carbon emissions.
Let’s look at the main reasons behind this growing popularity.
Top Benefits of HVO Fuel
1. Up to 90% Reduction in Greenhouse Gas Emissions
HVO fuel can reduce carbon emissions by as much as 90% compared to traditional diesel. Because it’s derived from renewable and waste sources, its life-cycle emissions are significantly lower, helping businesses and individuals shrink their carbon footprint almost instantly.
2. Fully Renewable and Sustainable
Unlike fossil fuels, HVO is made from renewable materials that can be replenished naturally. Most suppliers ensure that HVO feedstocks are certified under international sustainability standards, ensuring ethical sourcing and environmental protection.
3. Excellent Engine and Boiler Compatibility
One of HVO’s biggest advantages is that it’s a “drop-in” fuel. This means most existing diesel engines and oil-fired heating systems can run on it without modification. It meets EN 15940 standards for paraffinic diesel, ensuring full compatibility with modern engines and burners.
4. Superior Performance and Reliability
HVO fuel offers outstanding cold weather performance, remaining fluid at temperatures as low as -32°C — perfect for the UK’s unpredictable winters. It also has a longer shelf life (up to 10 years) and doesn’t suffer from microbial growth or oxidation issues common with biodiesel.
5. Cleaner Combustion and Lower Maintenance
Because it contains virtually no sulphur, metals, or aromatics, HVO burns cleaner, producing fewer particulates and pollutants. This results in less engine wear, reduced filter blockages, and lower maintenance costs over time.
6. Supports Corporate Sustainability Goals
For UK businesses, especially in logistics, agriculture, and construction, switching to HVO is an immediate and effective way to demonstrate ESG (Environmental, Social, and Governance) commitment. It allows companies to report real, measurable emission reductions without investing in costly equipment upgrades.
Common Uses of HVO Fuel in the UK
HVO fuel is incredibly versatile, making it suitable for a wide range of applications across domestic, commercial, and industrial sectors.
1. Transport and Logistics
Many fleet operators are now switching to HVO to decarbonise their operations. From delivery vans to heavy goods vehicles, HVO offers the same performance and efficiency as diesel while dramatically lowering CO₂ emissions.
2. Construction and Agriculture
On construction sites and farms, HVO powers everything from generators and diggers to tractors and excavators. Its stability and reliability make it ideal for remote and outdoor use where diesel has long been the standard.
3. Heating Systems (Domestic and Commercial)
For homes and businesses using oil-fired boilers, HVO offers a simple path toward renewable heating. It can often be used with little or no system modification, providing a greener alternative to kerosene or gas oil.
4. Power Generation
Backup generators, particularly in hospitals, data centres, and manufacturing plants, can operate efficiently on HVO. The clean combustion reduces noise, smell, and emissions during testing or emergencies.
5. Marine and Off-Road Applications
Boats, off-road machinery, and other non-road mobile equipment can also run on HVO, helping reduce pollution in sensitive environments such as marinas and nature reserves.
Compatibility Guide: Can You Switch to HVO Fuel?
One of the most appealing aspects of HVO is its broad compatibility.
- Diesel Engines: Most modern diesel engines can run on HVO without modification. It’s compatible with Euro 5 and Euro 6 engines, as well as older models. Many manufacturers, including Volvo, Mercedes-Benz, and Scania, already approve HVO use in their vehicles.
- Heating Oil Systems: Many oil-fired boilers and burners can operate on HVO with minimal adjustment. However, it’s recommended to consult your boiler technician or fuel supplier before switching.
- Fuel Storage: HVO can be stored in the same tanks as diesel or heating oil. It’s stable for long periods, making it ideal for seasonal or emergency use.
If you’re unsure, most UK HVO suppliers offer compatibility checks and technical guidance before transitioning.
Environmental Impact of HVO Fuel
When assessing sustainability, it’s important to consider the entire lifecycle of a fuel — from feedstock sourcing to combustion. HVO performs exceptionally well in this regard:
- It uses waste oils and residues, reducing landfill waste.
- It’s biodegradable and non-toxic, minimizing soil and water contamination risk.
- It contributes to the circular economy, reusing resources that would otherwise go to waste.
- Its production process is energy efficient, and emissions from use are up to 90% lower than mineral diesel.
For UK organisations working toward carbon neutrality, HVO represents one of the fastest and most practical solutions available today.
