4.6 Advanced bio-fuels (non-electric backstop technology)

Advanced biofuel represents a new generation of fuel coming from the conversion of woody biomass into biofuels. This conversion is subject to a learning by researching curve and represent a backstop technology. Advanced biofuels is a substitute to oil in the non-electrical sector.

The new production capacity of non-electric backstop technologies are bounded by the potential in advanced biofuels, following a logistic curve over time:

\[ NEL_{nelback}(t+1,n) - NEL_{nelback}(t,n) \le \left( 1 - \frac{NEL_{nelback}(t+1,n)}{advbiofuel\_pot(n)} \right) \times NEL_{nelback}(t+1,n) \]
