SeaChange Group, has won a patent for an eco-hybrid fuel technology proven to reduce NOx, particulate matter and greenhouse gas emissions.
In collaboration with the Maine Maritime Academy, the SeaChange Group has developed a hybrid fuel technology for direct-injection engines. The solution comprises diesel and glycerol, an inexpensive, renewable by-product of the bio-diesel industry.
The team observed a reduction of 25 to 50 percent in smoke emissions compared to an ultra-low sulfur diesel fuel at an equivalent power output. Emissions of mono-nitrogen oxides (NOx) were reduced by five to 15 percent, with the team finding a general trend in emission reductions in line with an increasing glycerol concentration.
Also corresponding to a higher concentration of glycerol in the fuel however is a lower energy density and therefore, an increase in overall engine fuel consumption.
Dr Richard Kimball, Director and Associate Professor of Engineering at the Marine Engine Testing and Emissions Laboratory (METEL) said, “ International shipping has come under stringent emissions regulations and ship operators around the world are looking for drop-in fuels such as this one to reduce emissions and maintain engine power and fuel efficiency. ”
