Our patented diesel/glycerol Bio-Eco-HybridTM Fuel (Bio-EHF)

  • is a “Drop in” Fuel
  • is Cost Effective
  • and reduces Emissions

Our Bio-EHF solutions offer viable alternative energy options to improve the environmental sustainability within the following target applications:

  • Off-road Engines
    • Marine/Rail/Construction
  • Stationery Power and Steam
  • Commercial Heating

Shipping Pollution - Smoke Emissions from traditional fuelOur Bio-EHFs offer many fueling advantages compared to traditional fuels. Our products utilize glycerol, a high-volume by-product of biodiesel manufacturing. Bio-EHFs emulsifies it into diesel/biodiesel to create clean burning, reduced cost fuels.  Glycerol improves burning characteristics and inhibits the formation of unwanted particulates (soot). Since glycerol is bio-renewable, its’ use offsets greenhouse gas emissions.

These attributes are important to the maritime, rail, heavy equipment (e.g., earthmoving), and stationary power applications which are all facing new, increasingly stringent emissions regulations.  These industries operate either internal combustion engines or open flame burner systems which currently consume traditional #2 distillates and biodiesel. Domestically, the average daily consumption rate from these industries is 832,000 barrels according to the Energy Information Agency’s 2010 figures. This accounts for 23% of all #2 distillates consumed. They can all seamlessly switch to Bio-EHF with no required equipment modifications.

Fuel Emulsions

Emulsification is a well-established, scalable technique for incorporating aqueous-phase materials into oils, such as diesel or biodiesel. This process uses intense liquid shearing forces to create a fine dispersion of droplets, typically on a micron- or nano-scale, within the bulk oil. The dispersed droplets containing glycerol and water give the fuel its milky appearance.

Biodiesel/Glycerol emulsified into Bio-Eco-Hybrid Fuel

Surfactants stabilize the oil-water interface and stop the droplets from coalescing; a process in which droplets merge and grow. When introduced into a dual-phase liquid, like biodiesel and glycerol, they preferentially align at the liquid-liquid interface stabilizing the droplet. The stabilization potential of a particular surfactant depends on its structure and the glycerol droplet/ fuel interface conditions. Without surfactants, the glycerol and fuel would separate within minutes, whereas Bio-Eco-Hybrid Fuel has demonstrated stability for over 1 year. Our surfactants have been carefully optimized and play an important role in fuel manufacturing.

Hundreds of surfactants were analyzed to develop Bio-EHF for long-lasting performance.

Glycerol is a Bio-Renewable Resource

Glycerol is a plentiful bio-renewable resource primarily produced during transesterification of plant lipids (triglycerides), notably as the by-product of biodiesel production.  In 2013, nearly 1.8 billion gallons of biodiesel were produced domestically which equates to approximately 132 million gallons of glycerol. There is enough glycerol to offset approximately 2 million barrels of diesel fuel energy.

Our Bio-Eco-Hybrid fuel will take this renewable by-product, which is often just a waste to the manufacturer currently, and use it to help control emissions, and increase profitability for the manufacturer. Call SeaChange at (207) 274-4060 or email us to learn more.
