Cummins Diesel, page-2

I see a massive market for optiblend, particularly in China and especially in the USA with the shale gas revolution.

Below is a good description of what optiblend is, from recent qtrly report:

Optiblend™ Background Eden has developed an efficient dual fuel system that is capable of operating on diesel engines and displacing up to 70% of the diesel fuel with natural gas. If Hythane™ (hydrogen enriched natural gas) is used in place of natural gas, the displacement of diesel fuel could be as high as 80%. The use of the natural gas will greatly reduce greenhouse gas emissions and, in places where natural gas is cheaper than diesel, will also reduce fuel costs. It has significant market potential particularly in the diesel powered generator set (“genset”) market. As a result of the increase in shale gas recovery in USA, the lower priced natural gas has resulted in a large market in USA for the conversion of these diesel engines to operate on a dual-fuel system of both natural gas and diesel is anticipated. Depending upon the size of the engine and the number of hours per day that it operates, payback times for the conversions are mostly a lot less than 12 months, so the cost is minimal compared to the replacement cost of a natural gas generator.
