OptiBlend Cummins, page-5

Yes plough,
I am aware that the concept of dual fuel diesel engines has been there for half a century.
It is only now that it has taken off because of the shale revolution.
It is touted that drill rig power units are about 8,000 in the US ....5% have been retrofitted with dual fuel kits in the last few years.
Almost all engine designers are building dual fuel engines.
The target market for Optiblend will likely be mainly the older stock & it will be competing with other kits.
Other backup generators may join the trend giving a sizable market of which Optiblend needs to carve a share.....Being endorsed by Cummins is a credit.
