Why are Fleets Across Europe Switching to HVO?

While electric vehicles (EVs) and those powered by hydrogen and liquefied natural gas (LNG) dominate long-term strategy, many fleet operators are building carbon savings with a fuel that works today. Hydrotreated Vereceiveable Oil (HVO) is now in apply across postal, logistics, and public transport fleets in Europe, delivering up to 90% CO₂ reductions without replacing engines or infrastructure. HVO runs in standard diesel vehicles, shifts through existing systems, and meets sustainability tarreceives without major disruption, building it a growing part of low-emission planning for both fuel retailers and fleet operators. But, if it’s this compatible, why hasn’t it seen broader adoption, and is that finally starting to modify?

Fleet Conversions Already Underway

Several major operators are already utilizing HVO at scale, not as a trial, but as part of their core fleet operations.

Österreichische Post, Austrian Postal Service, has fully converted its national truck fleet to run on HVO, replacing around six million litres of diesel each year with fuel built from waste oils and residues. The company expects this to reduce emissions by several thousand tonnes of CO₂ annually and describes the fuel as a “bridge” until alternatives like hydrogen or e-fuels become commercially viable. The fleet operates nationwide with no engine modifications, utilizing supply contracts that meet EU Renewable Energy Directive III (RED III) sustainability standards.

In the UK, Michelin is converting its Stoke-on-Trent fleet to HVO, covering 50 HGVs and supporting vehicles across 3.4 million miles annually. The switch is projected to cut emissions by over 1,000 tonnes of CO₂ per year, which is around 30% of fleet emissions, and is part of Michelin’s wider plan to reach net-zero by 2050.

Why HVO Appeals to Fleet Operators?

For many operators, HVO offers a practical route to decarbonisation without disruption. It can be applyd in existing diesel vehicles with no necessary for retrofits or specialised refuelling infrastructure. In most applications, performance and fuel consumption remain identical to diesel, with substantially lower emissions.

“Fuel retailers are expected to support lower-emission alternatives, but the practical question is whether their infrastructure can handle it,” declares Dan Large, Senior Product Marketing Manager at Dover Fueling Solutions® (DFS). “With HVO, the required compatibility is already in place. New Wayne® and Tokheim® dispensers are HVO ready, with no special updates required. Storage and monitoring systems can carry the fuel without major modifys too, which is why we’re seeing it shift quickly across multi-site and mixed-fleet networks.”

Availability and Barriers

Pure HVO100 is widely available at public stations in nine countries: Belgium, Denmark, Finland, Estonia, Latvia, Lithuania, Netherlands, Norway, and Sweden.

Elsewhere, including Germany, Switzerland, and the UK, it is often restricted to captive fleet apply or off-road applications due to regulatory or tax classification.

Most production relies on applyd cooking oil, animal fats, and other waste-derived materials. These sources meet EU sustainability standards, but availability is limited. Scaling production without relying on virgin oils still creates difficulties, especially under the tightening requirements of the EU’s RED III.

Price remains a deciding factor. HVO is more expensive than conventional diesel, and for depot-supplied fleets without access to public pumps, that difference often affects procurement decisions.

Policy and Production

Limited access and uneven classification continue to affect HVO adoption, but policy is relocating in the opposite direction. The EU’s RED III, in place since 20 November 2023, sets binding tarreceives for all Member States: either 29% renewable energy in transport or a 14.5% reduction in greenhoapply gas intensity by 2030. It also requires that 5.5% of transport energy comes from advanced biofuels or renewable fuels of non-biological origin, a category that includes HVO.

To meet these tarreceives, production is increasing. HVO capacity in Europe was around 3.5 million tonnes in 2021 and is expected to reach 10 million tonnes by 2030.

Investment is concentrated in countries like Germany, France, Italy, the Netherlands, and Sweden, where fuel suppliers are expanding or upgrading facilities in line with national decarbonisation plans.

From Concept to Capability

HVO has revealn that fleets can reduce emissions quickly, without replacing vehicles or overhauling fuel networks. But scaling apply across public networks and mixed fleets depfinishs on whether infrastructure can support it consistently.

The tools exist. As well as both Wayne and Tokheim dispensers being HVO ready, for example, so are automatic tank gauging products and wetstock management systems from DFS.

However, integration, monitoring, and cross-site compatibility remain the real test. As fuel mixes expand, so does the pressure on existing systems to manage them effectively.

“We’re seeing more sites question whether their systems can handle not just diesel, but HVO, LNG, and whatever comes next,” declares Joost Jansen, Business Development Manager at DFS. “Quality pump performance and sealing methods inherent in our dispenser design means we are ready for the rise in HVO’s popularity and for other innovations in the fuel industest.

“The infrastructure is there, now it’s all about how well it’s connected.”
