What is the Energy ROI of the solution ? From my understanding, biofuel EROI is rather poor, and does not make much economic sense in the long term.

I believe you are referring to ethanol based biofuels, which have significantly reduced energy density and require engine modification.

This technology is a plant oil based technology, and requires no engine modification. It's just fuel that comes from plants, and you can put it in your vehicle right now and drive.
