More about HVO
A fossil-free alternative

What is HVO fuel?

HVO stands for hydrotreated vegetable oil, sometimes known as Renewable Diesel. Part of the paraffinic family of fuels, it is a fossil-free alternative to mineral diesel, resulting in up to 90% reduction in Greenhouse Gas emissions*. It is also specially formulated to deliver a cleaner burn, and produces significantly lower NOx and particulate matter**.

Choosing this alternative fuel can help you not only reduce your overall carbon footprint, but also reduce the local emissions of your operations.

At Watson Fuels, we are committed to helping you reach net zero. Not only can we supply your HVO but you can also purchase it as Carbon Offset Fuel, which effectively counteracts the remaining CO2 emissions that you can’t reduce.

How is HVO made?
HVO is part of the paraffinic fuel family. It is a second-generation biofuel, also known as an advanced biofuel or renewable diesel, made from vegetable oils or animal fats. Unlike first-generation biofuels, these raw sources are processed using a specialist hydro-treatment to achieve high levels of purity. The result is a stable fuel with a long-shelf life and excellent performance year-round.

Who is HVO for?
HVO is a drop-in replacement for diesel. It delivers an efficient and reliable performance for vehicles and machinery across industries.

•  Construction equipment
•  Fleet vehicles
•  Agricultural machinery and vehicles
•  Manufacturing machinery
•  Industrial trucks and tankers
•  Commercial boilers and burners

An effective drop-in replacement

Why choose HVO?

One key difference with HVO compared to other alternative fuels is that it is FAME-free. Its formulation gives it excellent cold weather properties, a long-shelf life and ultra-low sulphur combustion for a reliable fuel all year round.

Using HVO is an effective way to reduce the carbon footprint of your business. It is also a simple solution. HVO is a drop-in fuel replacement that has very similar properties to regular diesel, so you won’t need to drain or modify your tank. We can also work with World Kinect Energy Services to help you balance the higher price point of HVO by generating savings elsewhere in your fuel and energy supply.

Can I use HVO?

HVO is very similar in formulation to diesel, so it can be used in nearly all the same applications that you would use diesel. But it’s important to check with your manufacturer first – or our experts can look into this for you.

Does HVO perform well?

The cetane number gives you an indication of a fuel’s combustion speed. Mineral diesel has a cetane number of 51, biodiesel’s is between 50 and 65, while HVO’s cetane number is between 70 and 90. This means you can expect a better starting performance and less chance of waxing in very cold conditions.

Will HVO cause problems with my machinery?

There is less risk of HVO causing problems with your machinery compared to biodiesels. It has excellent cold weather properties and ultra-low sulphuric combustion, which helps to extend service intervals.

Do I need to drain my tank to use HVO?

HVO meets EN15940, meaning you can use it as a drop-in replacement. You don’t need to drain your tank or modify your equipment to switch to it. We always recommend customers check with their vehicle manufacturer for full compatibility.

Is HVO the same as biodiesel?

HVO is different from biodiesel. Although both fuels are made from vegetable oils and animal fats, HVO is produced differently.

Biodiesels (also known as FAME) are made by esterifying the oil with methanol. Ester is a chemical compound in biofuel that makes it vulnerable to water, oxygen and diesel bug, which degrades the oil when stored.

HVO, on the other hand, is processed through hydrotreatment. This treatment ensures it is a pure and stable product with a lower risk of contamination and degradation. For this reason, HVO has a longer shelf life.

Does HVO last longer than diesel?

Yes, as HVO is FAME free it has a much lower risk of oxidation and degradation in storage, and therefore a significantly longer shelf life than regular diesel and gas oil. We always advise you to carry out regular tank care and maintain good storage conditions to protect your fuel.

What is second-generation biofuel?

First-generation biofuels, sometimes called FAME or UCOMe, are alternative fuels made from vegetable oils and animal fats. Second-generation biofuels are made from the same materials but are processed differently for a more advanced performance.

HVO is a second-generation fuel, which is part of the paraffinic diesel family. These fuels are synthetic oils with a low aromatic and naphthenic hydrocarbon content and no sulphur, which gives them a high purity level. This purity reduces the CO2 emissions produced when the fuels are burned.

Is there any palm oil in HVO?

No virgin crops are used in any of our HVO fuel and any crop waste is certified back to field/plantation level. We do not supply fuel made from Palm Oil, POME or any palm related source. Crop waste used to create our HVO is managed and certificated under international accreditation schemes.
