In recent years, Hydrotreated Vegetable Oil (HVO) fuel has attracted significant attention across the United Kingdom as a cleaner and more sustainable alternative to conventional diesel and heating oil. Businesses, farmers, and even households are exploring it as part of their transition to greener energy. However, with its rising popularity comes a wave of confusion and myths that often cloud decision-making.

To help UK users make informed choices, this article unpacks the most common misconceptions about HVO fuel and sets the record straight with clear, evidence-based explanations.

Misconception 1: HVO Fuel is Just Another Form of Biodiesel

One of the most widespread myths is that HVO is simply another name for traditional biodiesel. While both are derived from renewable feedstocks, the refining process and end quality differ dramatically.

• Biodiesel is produced through transesterification, a chemical reaction that creates Fatty Acid Methyl Esters (FAME).

• HVO Fuel, on the other hand, is created through hydrotreatment, a process that removes impurities such as oxygen and sulphur, producing a stable, paraffinic fuel.

This means HVO offers superior performance, longer shelf life, and better cold weather properties compared to standard biodiesel. In the UK climate—where winter temperatures can be unpredictable—this distinction is particularly important.

Misconception 2: HVO Fuel Damages Engines

Some UK users hesitate to switch to HVO, fearing it could harm engines or void warranties. In reality, HVO is a drop-in replacement for diesel and can be used in most modern diesel engines, generators, and machinery without modification.

Manufacturers including Scania, Volvo, and Caterpillar have already approved HVO in their engines. The fuel’s clean-burning properties can even reduce engine deposits, extend service intervals, and lower maintenance costs. Far from causing damage, HVO may actually help prolong the lifespan of machinery.

Misconception 3: Switching to HVO Fuel is Complicated

Another misconception is that transitioning to HVO involves costly equipment upgrades or operational downtime. In truth, the switch is straightforward:

• HVO is chemically similar to conventional diesel, making it fully compatible with existing tanks and infrastructure.

• Businesses in transport, agriculture, and construction can begin using HVO immediately, often requiring nothing more than a routine tank clean to remove old residues.

This ease of integration makes HVO an attractive option for companies under pressure to cut emissions without major disruption to operations.

Misconception 4: HVO is Not Readily Available in the UK

While HVO was once considered niche, availability across the UK has grown significantly. Many fuel distributors and suppliers now stock HVO due to rising demand from sectors such as haulage, construction, and heating.

Although not yet as widely available as red diesel or kerosene, supply chains are expanding rapidly, supported by government initiatives and corporate sustainability commitments. Forward-thinking UK businesses are already securing reliable supply contracts to future-proof their fuel strategy.

Misconception 5: HVO Fuel is Too Expensive to Be Practical

Price is often the biggest concern for those considering HVO fuel. It’s true that HVO can cost slightly more per litre than fossil diesel, but this view overlooks the long-term financial and environmental benefits:

• Lower maintenance and reduced downtime mean fewer hidden costs.

• Using HVO helps businesses meet sustainability targets and may improve eligibility for eco-friendly tenders.

• The reduction of up to 90% in greenhouse gas emissions adds brand value and reputational benefits, especially as consumers and regulators in the UK demand greener practices.

Seen in this light, HVO is not simply a fuel—it is an investment in future resilience and compliance.

Misconception 6: HVO Fuel Offers Limited Environmental Benefits

Some sceptics believe HVO is a token gesture rather than a meaningful step towards sustainability. The reality is quite the opposite.

HVO fuel delivers:

• Up to 90% lower lifecycle CO₂ emissions compared with fossil diesel.

• Minimal levels of nitrogen oxides (NOx) and particulate matter, contributing to cleaner local air quality.

• A renewable supply chain, since it is made from sustainable feedstocks such as waste oils and residues.

For UK companies aiming to align with Net Zero 2050 goals, adopting HVO is one of the most immediate and impactful actions available.

Misconception 7: HVO Fuel is Only for Large Corporations

Another myth is that HVO is exclusively designed for large businesses with deep pockets. In fact, HVO is increasingly being adopted by SMEs, farmers, domestic heating users, and even event organisers.

• Farmers are turning to HVO to reduce emissions from tractors and machinery.

• Construction firms use it to cut the environmental impact of site generators.

• Homeowners in off-grid areas are exploring HVO as a cleaner alternative to kerosene for heating oil tanks.

Its flexibility makes it relevant across multiple UK industries, not just for big names with large sustainability budgets.

Final Thoughts: Clearing the Air on HVO Fuel

Hydrotreated Vegetable Oil is not just a buzzword—it’s a practical, sustainable fuel that can help the UK transition towards greener energy without massive disruption. By dispelling misconceptions about cost, availability, and performance, it becomes clear that HVO fuel is a credible, future-ready alternative to conventional fossil fuels.

For UK businesses and households, understanding the facts about HVO is key to making informed, environmentally responsible choices. As supply chains expand and costs balance out, HVO could play a central role in shaping the nation’s cleaner energy landscape.
