New White Diesel Fuel Can Save Energy, Reduce Emissions

(3BL Media/Justmeans) - One thing we can say for sure: people are not likely to give up the convenience, freedom and utility offered by motorized transportation as long as there are options available. Given that our current fleet of gasoline and diesel powered cars and trucks are emitting huge amounts of climate-wrecking carbon dioxide, it’s clear that things have got to change. With all the options on the table: hybrids, electric, hydrogen, compressed air, and a myriad of alternative fuels, it’s anyone’s guess how things will look, even a few years from now, never mind a couple of decades down the road.

Ultimately, if we are going to stick around, we’ll be driving cleaner cars—the cleaner the better, and the sooner the better. What if we could drive a car that used today’s technology, only powered by burning water? That would certainly be very clean—no carbon, no methane, no particulates, sulfur or nitrogen. Of course, we know that water doesn’t burn, but diesel fuel does. And researchers have known for years that a small amount of water can be added to diesel fuel to extend fuel economy while also burning cooler and cleaner. Generally speaking, experiments have found reductions as high as 90% in particulate matter as well as a 37% decrease in NOx.

This can be accomplished with a water-fuel emulsion achieved by blending the two liquids together as if making a milkshake. Researchers in New Zealand found that a mixture containing 12-15% water worked best.  The problem with this is, like with a milkshake, that if you let it sit for a while the two liquids will begin to separate at which point the engine will stall. So the challenge has been to find a way to stabilize the emulsion.

Now, a British company called SulNOx Fuel Fusions claims to have found a way utilizing nanotechnology to create fuel-water emulsion that they call “white diesel.” According to a company press release this emulsion improves fuel economy and reduces emissions “by improving atomization of the fuel and lowering engine temperatures. “

The presence of water in the emulsion has the effect of “breaking down the fuel particles [which] increases their surface area which helps the fuel to burn more completely and efficiently.”
