Have you considered HVO fuel?
HVO fuel (Hydrotreated Vegetable Oil) is a fully renewable and drop-in diesel alternative that reduces net CO2 emissions by up to 90% whilst adhering to EN 15940 standards and Fuel Quality Directive 2009/30/EC Annex II. It’s free from fossil and FAME content, which means that it does not suffer from the same performance issues as traditional fuels, such as gelling in cold weather.
While biodiesel is a first-generation biofuel, HVO is an innovative second-generation biofuel that’s made from certified waste and improves performance.
The benefits of using HVO fuel:
- Synthetic, second-generation paraffinic fuel
- High cetane number of up to 90 improves starting performance
- Low cloud point of -27°C reduces the risk of waxing in cold temperatures
- Storage life of up to 10 years, making it ideal to store in bulk
- Up to 90% reduction of net CO2 emissions
- OEM approved by a vast number of manufacturers*
- Zero FAME, sulphur, aromatics, fossil content and metals
- Miscible with regular diesel – no need for modifications or upgrades to existing infrastructure
- Reduced need for regular fuel maintenance
*Please check with your vehicle or machinery’s manufacturer before switching to HVO.
