The Impact of ULSD's and Bio Blends

Refuel was developed to address specific market and product changes that have occurred over the past decade. This is largely a result of an increased awareness of environmental impacts of diesel fuel and its exhaust.

Specifically, these factors include:

  • Widespread use of ultra low sulphur diesel and bio-diesel blends
  • Increased demand on power grids and related increase in power failures and outages
  • Mandated separation of essential and non essential generator systems and fuel sources
  • Increased reliance and demand for backup power for mission critical infrastructure do to the negative effects of global warming
  • Introduction of high performance diesel engines to meet emission requirements
  • Increased importance placed on reducing carbon footprints and green house gases

Before these market changes, traditional solutions like burning heating fuel in backup generators, inline filtration, and additives were enough to ensure a reliable supply of fuel and generator performance.

The most significant change affecting the industry is the de-sulphurization of distillate fuels such as diesel. Government regulations on emissions have recognized a reduction from 5,000 parts per million (ppm) to 15ppm sulphur over the last two decades. This has made a substantial impact on reducing green house gases but has also had an impact on how fuel and water interact. Prior to de-sulphurization, water settled on the bottom of storage tanks because it weighed more than the fuel. By leaving some distance between the tank floor and the fuel supply pickup line, you could limit the risk of ingesting water.

Sulphur served multiple purposes in fuel. One of the most critical functions it served in diesel engines was as a natural lubricant. Manufacturers of fuel had to replace the natural lubricating properties found in sulphur with additives.

These market changes have had a significant and unintended impact on emergency systems, changing how fuel is managed and stored to prevent a loss in system integrity.
