Currently, if we look at the second generation, there are really two types of innovation: you have biological processes using enzymes and you have the thermochemical pathway. What we see now is that there is a portfolio of maybe ten companies as a maximum that are ready to commercialize and that are developing—have concrete or fill in the ground and are building plants and developing commercial facilities. Enerkem is part of this first wave of commercial advanced biofuels facilities.
In the future, what we expect to see is continued innovation in synergies with the first-generation ethanol. They're also looking at other things. Also, I think algae is going to be looked at in jet fuel. Right now, in some cases it is technically feasible for jet fuel but commercially not viable—the costs are too high. So there's going to be more innovation.
We see the third generation as probably being at the pilot-demo phases in terms of technical and commercial viability.
