Gen3d Renewable Diesel

Gen3d Renewable Diesel is the next generation of renewable fuel. It matches the chemical and physical properties of petroleum diesel, allowing seamless integration into existing infrastructure — pipelines, storage tanks, pumps, and engines. According to California’s Air Resources Board (CARB), Renewable Diesel consistently achieves one of the lowest carbon intensities among renewable fuels, making it a powerful tool for reducing transportation emissions while maintaining full performance and compatibility.

Why Gen3d Renewable Diesel?

  • Identical to Petroleum Diesel — Same chemical composition and performance characteristics. Use it in the same pipelines, storage tanks, and fueling stations as conventional diesel.
  • Superior Cetane Value — Higher cetane number than petroleum diesel, delivering smoother combustion, better cold starts, reduced engine noise, and improved efficiency — similar to high-octane benefits in gasoline.
  • Matching Energy Density — Unlike cellulosic ethanol (which has significantly lower energy content), Gen3d Renewable Diesel provides the same energy density as petroleum diesel — equivalent miles per gallon and vehicle performance.
  • Fuel Output Flexibility — Production technology enables Renewable Diesel to meet strict aviation fuel specifications (e.g., jet fuel) as well as diesel, gasoline, and heating oil standards — true drop-in versatility.
  • Feedstock Flexibility — Can be produced from any lipid-based feedstock — soybean oil, used cooking oil, animal fats, palm oil, and more. Switch feedstocks based on cost, availability, and sustainability.
  • High Efficiency Operation — Plants achieve up to 85% thermal efficiency, using roughly half the energy of conventional biofuel production processes.
  • Low Capital Costs — Gen3d Renewable Diesel facilities cost about the same as — or even less than — traditional biodiesel plants of similar capacity.
  • Very Low GHG Emissions — Significantly lower greenhouse gas emissions than corn ethanol or soy biodiesel. When produced from waste grease or used cooking oil, carbon intensity can be lower than cellulosic ethanol.
  • Environmental Benefits — Effectively CO₂ neutral over its lifecycle when using sustainable, low-carbon feedstocks.

Biodiesel vs. Renewable Diesel: Key Differences

Property Biodiesel (FAME) Gen3d Renewable Diesel
Chemical Structure Ester-based (FAME) Hydrocarbon-based (paraffinic, chemically identical to petroleum diesel)
Infrastructure Compatibility Limited blending (B20 max common) Full drop-in (up to B100)
Cetane Number 45–55 70–90+
Cold Flow / Cloud Point Higher (poorer cold performance) Excellent cold flow properties
Energy Density Lower than petroleum diesel Equivalent to petroleum diesel
Stability & Storage Prone to oxidation and microbial growth Highly stable, long shelf life
Production Process Transesterification (with methanol) Hydrotreating / hydrocracking (hydrogen + catalyst)
Cold Soak Filterability (ASTM D7501) Often fails with high-gel feedstocks Consistently passes — even with challenging feedstocks

Both fuels can use the same feedstocks (soybean oil, used cooking oil, animal fats, etc.), but the hydrotreating process transforms Renewable Diesel into a hydrocarbon identical to petroleum diesel — eliminating biodiesel’s limitations.

Addressing Cold Soak Filterability Concerns

ASTM D7501 Cold Soak Filtration Test (CSFT)
The test measures how well biodiesel flows when chilled then poured through a filter. Biodiesel from high-gel-point feedstocks (yellow grease, WVO, animal fats) or variable blends often fails this test due to haze, solids, or viscosity increase.

Three main approaches to pass CSFT:

  • Select low-gel-point feedstocks (e.g., soy) — expensive and supply-limited
  • Add cold-flow improver additives — recurring cost and variable effectiveness
  • Distill the biodiesel — produces the purest, most consistent product with excellent cold flow

Distillation eliminates impurities (glycerides, soaps, sterol glucosides) that cause cold soak failures, creates homogeneous fuel, reduces sulfur in high-sulfur feeds, and removes the need for additional washing. Distilled Renewable Diesel consistently passes ASTM D7501 while maintaining full tax credit eligibility.

Quick Cold Soak Test You Can Perform

Concerned about your biodiesel passing ASTM D7501? Try this simple check:

  1. Place a jar of your biodiesel in the refrigerator for a few hours.
  2. Check for:
    • Clarity — Does it become hazy or cloudy?
    • Solids — Do you see solids forming or crystallization?
    • Viscosity change — Is the chilled fuel noticeably thick and slow to pour?
  3. If any of these occur, your biodiesel may fail the cold soak filtration test.

Gen3d Renewable Diesel distillation eliminates these issues, producing a premium, ASTM-compliant product every time.
