The Ultimate Guide to HVO Fuel

Getting you ready for the red diesel tax changes

Discover the power of renewable diesel in unlocking significant emissions savings for your business

An intro to Certas Energy HVO

The countdown to Net Zero 2050 has begun. Energy legislation is increasingly weighted towards cleaner alternatives and away from fossil fuels. ESG strategies are also putting a spotlight on commitments to lower the environmental impact of everyday operations. 

So as businesses get to grips with evolving regulatory requirements and corporate sustainability goals, the question is; how can they adapt, and quickly? 

We have one answer: Hydrotreated Vegetable Oil (HVO). 

With the ability to immediately and significantly reduce emissions, Certas Energy HVO holds the power to propel businesses forward to a cleaner, brighter future. 

Let’s take a deep dive into this promising low carbon alternative diesel and the benefits it can deliver.

What is HVO?

HVO is a drop-in alternative fuel, manufactured from 100% renewable and sustainable waste.

One of the cleanest, most high quality fuels currently on the market, it can be used as a replacement for regular fossil diesel and can significantly reduce fuel-related net CO2 emissions by up to 90%, without any engine modifications.

Practically FAME, sulphur and fossil free*, it is made using raw materials, such as vegetable fats and oils. Unlike conventional biodiesel, HVO is a fully saturated hydrocarbon, which makes HVO cleaner burning and ensures a longer shelf life.

Who can use HVO?

HVO is suitable for on- and off-road vehicles, plant and machinery across a range of industries, including construction, agriculture, transport and logistics, marine and the public sector.

Alongside its strong sustainability credentials, HVO can be seamlessly integrated into existing vehicles and machinery. This makes it ideal for industries that want to realise significant carbon reduction but find it difficult to decarbonise due to current technology and electrification shortcomings.

How much is HVO?

HVO does cost slightly more than regular diesel but as demand and supply increase, we expect that the price will start to decrease.

Given the withdrawal of red diesel allowances for many industries, alternative fuels are becoming more popular as a cleaner, compliant and convenient alternative to white diesel. They are also much cheaper to implement than other sustainable solutions, which require investment in infrastructure.

As a drop-in alternative, HVO can be used in vehicles or equipment designed for standard diesel, without any changes to the engine or infrastructure. Tanks also do not need to be drained, flushed or cleaned out. As capital expenditure or investment is not required, HVO offers a viable and accessible route towards decarbonisation, without disruption or delay.

HVO meets the international fuel standard EN 15940, the specification for paraffinic diesel.

Yes. HVO is a type of biofuel – also known as a renewable diesel – produced from waste vegetable oils and fats.

Yes. HVO fuel is a completely compliant fuel that can be legally used to power on and off-road machinery and vehicles. HVO fuel can also be used as a heating solution, with minor boiler adjustments. Find out about the Future Ready Fuels project, which Certas Energy is helping to lead, with the goal of making HVO-powered boilers a reality.

Yes – HVO is paraffinic diesel fuel made via hydrotreatment. As it uses primarily waste vegetable oils and fats as the feedstock, it is both renewable and sustainable.

Certas Energy HVO provides an immediate opportunity to reduce greenhouse gas (GHG) emissions by up to 90% over the product life cycle, without the need for changes to engine, machinery or infrastructure.

• HVO has a 10-year shelf life
• Low CFPP at -30 degrees
• HVO fuel is completely biodegradable
• It is a ‘cleaner’ fuel, practically FAME and fossil free*
• HVO often offers improved combustion in diesel engines

As the UK moves towards the goal of net-zero emissions by 2050, the way we fuel businesses is changing. HVO provides an instant impact for businesses working towards a lower emissions future.

Furthermore, HVO is a highly stable FAME-free fuel with limited risk of microbial growth.

HVO is a highly stable, practically FAME-free* fuel with no risk of microbial attack.

HVO fuel takes fatty acid feedstock such as vegetable oils and puts them through a process called hydrotreating or hydrogenation.

When acids go through hydrotreatment, hydrogen is introduced, changing the molecular structure of the vegetable oil.

Uniform, more simple hydrocarbon molecules are created containing fewer impurities than fossil-derived diesel. As a result, HVO fuel burns more cleanly, releases fewer emissions and is more environmentally-friendly.

HVO fuel is fully interchangeable with traditional diesel and can be mixed or blended at any percentage. Visit our blog to discover our flexible fuelling options that allow you to trial or gradually transition to the renewable fuel.

Like all fuel, the price of HVO is variable. Cost depends on a number of factors, including market changes, volume, availability and location.

Alternative fuels, such as HVO, currently cost slightly more than conventional diesel but as demand and supply increases, the price difference will decrease.

Certas Energy HVO is produced and accredited to meet the international fuel standard BS EN 15940, the specification for paraffinic diesel, and the Fuel Quality Directive 2009/30/EC Annex II.

HVO does not require a different tank and so businesses can use existing tanks to store the fuel. Like all flammable fuel, HVO must be stored in a cool, dry place and should not be exposed to direct sunlight.

HVO offers a longer shelf life to conventional diesel: up to 10 years. As it is practically FAME free*, there is a decreased risk of filter blockages or water contamination of bulk HVO fuel stocks. It is also less harmful to the environment in the event of a leak or spillage, as it is biodegradable.

We offer a wide range of fully compliant fuel storage tanks and our tank specialists can provide product and installation guidance.

Not always as not all HVO is created equal. The level of greenhouse gas emissions savings can vary by product, as they do not come entirely from tailpipe emissions. Savings are based on a life-cycle, well-to-wheel calculation, taking into account feedstock, production processes and transportation. Businesses need visibility of the fuel’s upstream supply chain so that they can substantiate their downstream sustainability claims.

We only partner with Zemo accredited and/or ISCC certified HVO suppliers, each one having a fully validated and auditable supply chain. So, you can be confident about the governance of Certas Energy HVO and trust that it meets the highest auditable product standards possible.
