Our Renewable Diesel

NSRE produces a next generation “drop-in” biofuel (Renewable Diesel) that has all the performance, stability, and cold flow advantages of traditional petroleum based fuels with none of the negative environmental disadvantages. NSRE fuel also has all the environmental advantages of traditional biodiesel with none of the performance, stability, or cold-flow disadvantages. In short, NSRE offers the best of all worlds with a renewable fuel made from non-edible fats, oils, and greases. NSRE’s Renewable Diesel can be used “neat” or blended in any ratio with traditional petroleum based diesel.

NSRE’s Renewable Diesel can be used “neat” or blended in any ratio with traditional petroleum based diesel.

The fuel is also completely pipeline fungible, and has none of the disadvantages of either transesterfied biodiesel or petroleum based fuels. However our fuel has all the green advantages of biodiesel and all the performance, stability, and suitability advantages of petroleum based fuels. 

The key difference between renewable diesel and biodiesel is its chemical structure. Biodiesel contains fatty acid methyl esters (FAME), which are long, complex chains containing carbon, hydrogen, and oxygen. Renewable diesel is made up of totally organic hydrocarbons (hydrogen and carbon atoms only) just like petroleum diesel. This means renewable diesel is a 100-percent drop-in replacement fuel requiring no modifications to the existing fuel distribution infrastructure or the vehicle’s fuel system (even in today’s brand-new engines). These designer fuels are coveted by the military, railroads, and airlines, which are routinely doing successful demonstrations with the new fuel. Another difference is renewable diesel can be made from the sugars, starches, and cellulose material abundant in plants versus just using the seeds. Furthermore, with renewable diesel, various types of otherwise unusable waste streams can also be used as feedstocks.

 Traditional biodiesel (FAME)

Fuel can be blended in any blending ratio, i.e. 0–100% of the content.

Can be blended with fossil diesel, traditional biodiesel (FAME), or used “neat” in diesel engines.

As a “drop-in” fuel completely pipeline fungible and suitable for all existing fuel infrastructure from tanks, pipelines, pumps, and end user

Fuel blend may contain a maximum of 5–7%** of traditional biodiesel. Larger proportion may result in engine problems.

FAME also clogs filters, pumps and pipes. FAME begins separating after 30 days and begins growing micro organisms.

High water content in FAME makes it unsuitable for existing pipeline system. FAME must be trucked and tanked separate from petroleum fuels

Helps in meeting national biomandates and reducing greenhouse gas and exhaust gas emissions (e.g., PM, NOx, CO, HC) significantly.

Meets the strictest quality standards set by the authorities, logistics, and distribution companies, as well as car manufacturers and fuel using drivers.

Can be used in fuel blends to improve the overall quality of the fuel.

Helps in meeting national biomandates, but blending restrictions regarding FAME aimed at preventing engine problems limit the benefits the fuel blend offers.

Reaching the challenging biomandates for traffic with traditional biodiesel alone is not possible unless product specifications are modified to allow the use of lower quality diesel fuel.

Its use increases NOx emissions compared to fossil diesel.

Reduces greenhouse gas and tailpipe emissions (PM, NOx, CO, HC).

Increases NOx emissions.

Offers excellent storability.

Must be used before a specific “best before” date.

Its use does not require engine modifications or changes in the fuel’s logistical system.

Its use may cause engine problems.

Other benefits include

  •     Lower emissions — up to 80% less compared to petroleum diesel
  •     Chemically equivalent to petroleum diesel
  •     Requires no changes to fuel infrastructure or vehicle technology
  •     Can be blended in any proportion
  •     Stable, not oxygenated
  •     Superior cold-flow properties — more suitable for very cold weather conditions
  •     Higher energy content per volume compared to biodiesel

NSRE Renewable Diesel is superior to both petroleum based diesel and Fatty Acid Methyl Ester (FAME) biodiesel

Petro-Diesel Biodiesel Renewable Diesel

Cetane 40-55 50-65 75-90
Cold Flow Properties Basline Poor  Excellent
Oxidative stability Basline Poor Excellent 
Energy Content Baseline Lower Similar

Drop-In Biofuels Benefit:
Engine and Infrastructure Compatibility

Drop-in fuels are expected to be substantially similar to their petroleum counterparts and therefore minimize compatibility issues with existing infrastructure and engines.
