HVO is the new sustainable alternative that can be used as a drop-in replacement for gas oil/red diesel, and it can be used in all diesel engines.
What is HVO?
HVO or hydrotreated vegetable oil is a FAME-free (fatty acid methyl ester) and fossil-free environmentally friendly mineral diesel. It is synthetically made through the hydrotreatment
of either vegetable oils or animal fats and is manufactured from 100% renewable raw materials
such as corn or tallow. It is fully biodegradable and complies with EN15940 and ASTM D97 5.
Unlike biodiesel, it does not deteriorate over time and can be used in temperature extremes.
HVO fuel versus FAME diesel
Functionally HVO is almost identical to fossil diesel thanks to its paraffinic petrochemical structure.
This means it can be handled and used as a drop-in alternative without the need to update generating equipment and infrastructure, and there’s no need to clean out existing fossil diesel.
Whilst there are many other similarities, including energy content, density, viscosity and flash point,
HVO has a number of advantages over fossil fuels. The chemical process used in its manufacture ensures a consistent product that contains no esters or contamination.
HVO fuel meets the requirements of current legislation – it’s 100% bio and FAME-free, so it doesn’t face the issues of stability faced by many existing biodiesel and gas oil products. This makes HVO a much more stable product with a reduced risk of degradation when in storage due to zero FAME and sulphur content. The production process affords a shelf life of up to ten years.
With a high cetane number of greater than 70 and low cloud point of -32ᵒC, HVO provides improved
cold start performance, clean combustion and less chance of waxing in extreme temperatures than
Can HVO reduce harmful emissions?
Yes. Due to the consistent nature of HVO, combustion is more efficient. Independent tests have demonstrated a significant reduction in NOx, and therefore improved air quality.
