Reduced Emission Driving
with HVO Renewable Diesel.
Reduce your carbon emissions by up to 90%!
What is HVO?
Hydrotreated vegetable oil (HVO) is a low-carbon biofuel that works as a direct replacement for regular diesel. It is a high-quality renewable diesel produced from treating waste plant-matter with hydrogen, which means it does not release any additional carbon emissions into the atmosphere.
That means drivers of many existing diesel vehicles can simply swap to HVO fuel immediately, with no concerns about economy, functionality or reliability. HVO emits up to 90% less carbon emissions when compared to conventional diesel, while also providing multiple extra benefits including lower NOx emissions, biodegradability, longer shelf-life, and being fossil-free.
Can I use HVO in my car?
HVO renewable diesel is suitable with almost any diesel car. It is chemically identical to the regular diesel you find on our forecourts today. HVO has been approved for usage by most leading car & vehicle manufacturers and has a wide range of OEM approvals so can be used without any engine or equipment modification. Most modern cars will run the fuel without any trouble at all. Owners are advised to check their vehicle will take HVO before they try filling up.
HVO is safe to mix with regular diesel at any volume, so even if your tank has remaining diesel inside, you’re good to go. It is 100% interchangeable with regular diesel. So you can get started right away.
What are the benefits of HVO?
Many of us want to reduce our carbon footprint whether at home, at work, or on the road. However, this can be quite a challenge as this often means buying a new car or upgrading engines or equipment. But now there is an easy way to dramatically reduce the carbon footprint associated with your car without the hassle of having to make these costly changes. Thousands of Irish motorists are quickly discovering the benefits of making the switch from diesel to HVO as a low-carbon alternative.
HVO renewable diesel is a second generation biofuel made from waste plant matter such as vegetable oil and fats. Unlike conventional biodiesel, hydrogen is used as a catalyst instead of methanol, which makes it a cleaner burning fuel. It is an ethically sourced fuel with ISCC verification. HVO is quickly becoming the go-to alternative fuel for motorists looking to reduce the environmental impact of their reliance on fossil fuels.
Does HVO perform the same as diesel?
Yes, with HVO renewable diesel, there is no compromise in range or power. It’s reduced carbon emissions with the same power you’re used to! Making the switch can even deliver certain improvements to vehicle performance. As there are fewer impurities in HVO than conventional diesel, your car’s engine can be more economical with it’s fuel usage.
In addition, Nitrogen oxide emissions and particulate emissions can be reduced. These performance benefits are added to the major advantage of HVO, which is the whole-life CO2 emissions of the fuel. The associated carbon footprint is up to 90 per cent lower than that of regular diesel.

FAQs
HVO fuel is one of the cleanest fuels on the market. It’s a second-generation, synthetic, advanced renewable diesel alternative that eliminates up to 90% of net CO2 and significantly reduces nitrogen oxide (NOx), particulate matter (PM) and carbon monoxide (CO) emissions.
As a paraffinic, renewable fuel, HVO can be used as a drop-in alternative to fossil diesel, meeting EN 15940 standards and Fuel Quality Directive 2009/30/EC Annex II. There’s no need to modify existing infrastructure – you can simply top up and go.
When it comes to HVO fuel price, Certa can supply the renewable diesel to businesses across Ireland at a competitive rate, within a short time after purchase. In terms of price per litre, HVO fuel does have a premium over regular diesel, however, it offers up to 90% reduced net CO2 emissions without the cost of changing hardware.

HVO (Hydrotreated Vegetable Oil) is a renewable diesel made by hydrotreating vegetable oils, used cooking oils, and excess plant matter.
The feedstock is first purified to remove impurities and then processed with hydrogen at high temperatures (300–400°C) to eliminate oxygen, converting it into stable hydrocarbons. This process improves fuel quality, enhancing its cold-weather performance, storage life, and overall efficiency.
Unlike traditional biodiesel (FAME), HVO has a higher cetane number, fewer impurities, and does not degrade over time. It is a high-quality drop-in diesel that can be used in existing diesel engines without modifications, significantly reducing CO₂ emissions—by up to 90%—compared to fossil diesel while offering superior combustion properties and engine performance.
A second-generation biofuel is a fuel produced from non-food biomass, such as agricultural waste, forestry residues, algae, or used cooking oils, rather than directly from food crops like corn or sugarcane.
These biofuels are designed to be more sustainable than first-generation biofuels, which compete with food production. Second-generation biofuels, including HVO (Hydrotreated Vegetable Oil), cellulosic ethanol, and Fischer-Tropsch biodiesel, typically have lower carbon footprints and do not contribute to deforestation or food shortages. They offer improved efficiency, reduced emissions, and better compatibility with existing fuel infrastructure.
HVO fuel is perfectly suited to a wide range of industries as an alternative to diesel, such as construction, rail, events and public transport. It’s commonly used in:
- Portable generators
- Commercial boilers
- Agricultural tractors and machinery
- Boasts and vessels operating within inland waterways
- Construction equipment and machinery
- Industrial trucks and tankers
- A handful of events and Irish festivals, including Bloom, National Ploughing Championships, and Electric Picnic have already made the move to HVO fuel to power their portable generators and transportation.
Yes! HVO can be used as a direct replacement for kerosene heating oil with no requirement to modify your home heating system, boiler, or oil tank. However, in some cases, it may be recommended to empty your tank before mixing with HVO to ensure no impurities.
While you can use HVO as a direct replacement for kerosene heating oil, you can also blend both HVO and kerosene together.

Yes, absolutely! The similarities between mineral diesel and HVO mean that it can be used as a drop-in alternative in most cases. But it’s always best to check with your engine manufacturer first.
HVO fuel has OEM approvals from a wide range of manufacturers for a wide range of diesel engines. An OEM approval means that the fuel can be used with no risk of voiding the warranty of the vehicle or machinery.
Please consult the below list of manufacturers that have approved the use of HVO fuel in their engines to see if your hardware is covered. If your engine manufacturer is not included, give us a call and we will be able to contact the provider to determine whether your engine can use HVO. Many vehicle handbooks are now outdated so may not include HVO approvals yet, but it’s likely you can use HVO without any issues.
