Looking to get started with HVO? Hydrotreated – or hydrogenated – vegetable oil is a sustainable, low-carbon biofuel that derives from waste products and other biomass, which can reduce emissions by 85%. It can be used as a direct, drop-in alternative for fossil diesel and can be safely stored in all Western Global tanks.

This type of fuel has a number of benefits over mineral diesel, kerosene and first-generation biofuels. In addition to its environmental benefits, HVO has a long storage life of up to 10 years and a lower freeze point (-10ºC) than diesel (10ºC).

For most applications, HVO is completely interchangeable with diesel and can be blended in any ratio. If your OEM has approved the fuel, then there is no risk of voiding your warranty.

It’s clean burning properties reduce particulate production, which helps improve engine cleanliness and prolong machinery lifetime.

It is made by treating oils with hydrogen. It can be produced using a variety of feedstocks, including vegetable oils like soy and rapeseed, or waste fats such as animal fats or cooking oils.

The production process involves saturating feedstocks with hydrogen at temperatures above 300℃. The final process is isomerisation, which results in a fuel almost chemically identical to mineral diesel, but with additional benefits.


In the UK, there are no specific regulations. It follows the same regulations as regular oils such as diesel, kerosene, and blends.

Oil storage regulations specify that oil storage tanks above a certain capacity (depending on the industry) must have a secondary containment system with the capacity to store a minimum of 110% of the primary content. This is to capture leaks from the primary tank. All Western Global tanks are 110% contained.


Biodiesel is a first-generation biofuel made from fresh, organic matter. It is not a direct drop-in replacement for mineral diesel and is susceptible to oxidation and diesel bugs. It is also known to ‘gloop’ at low temperatures, due to its chemical composition.

A second-generation biofuel, it has similar properties to mineral diesel compared to biodiesel.


All Western Global tanks are designed to store HVO and other biofuels. Our standard tanks range from 1,000 litres to 100,000 litres, and with lockable equipment cabinets and lifespans of over 10 years, they are the number 1 way to store your fuel securely.

All our pumps are suitable as well. Please check with us whether your chosen pump package is also capable of working with first-generation biodiesel.

How to maintain your HVO fuel tank

All Western Global tanks are designed to be easily maintained with removable inner tanks or inspection hatches. We recommend regular inspections, including:

  • Check and replace filters where installed
  • Visual inspection for evidence of corrosion or damage
  • Check the bund for water, product or debris
  • Ensure venting devices are operational and free from obstruction

Reducing your emissions

HVO tanks can reduce carbon emissions by up to 85%, but this will vary depending on the feedstock used to make the fuel. Due to its clear burning properties, it also reduces particle emissions by up to 50%, helping to improve local air quality.

When you store your HVO in a Western Global fuel tank, you can reduce the number of deliveries to your site, which also means lower emissions from transport. Using an on-site storage tank with a fuel management system allows you to track fuel usage and receive regular updates live or via email, delivering accountability for every drop of fuel.
