I think that starting it out in limited uses would be a good start.  I know that Energize American targeted vehicle fleets for this reason.  I'm think that (relatively) fixed uses like farming, industry, and trucking would be a good start.  Ultimately, I think any new technology is going to have to start in those areas of the economy.  Because they require the least change in the distribution system.

On Kos, I mentioned that theoretically, the patent for this is held by the State of Indiana, through the Purdue Research Foundation.  Which should make the commercialization process very interesting.  If this works out, this is a lot of money that were talking about, it's a question of where that money goes.  Remember it was state spending that made this development happen.
