Global transport biofuel futures in energy-economy modeling: a review

Kapitel i bok, 2015

The high oil dependence and the growth of energy use in the transport sector have increased interest in alternative fuels as a measure to mitigate climate change and improve energy security. More ambitious energy and environmental targets and larger use of alternative energy in the transport sector increase system effects over sector boundaries, and while the stationary energy sector (e.g., electricity and heat generation) and the transport sector earlier to large degree could be considered as separate systems with limited interaction, integrated analysis approaches now grow in importance. In recent years, the scientific literature has presented an increasing number of energy-economic future studies based on systems modeling treating the transport sector as an integrated part of the energy system and/or economy. Many of these studies provide important insights regarding transport biofuels. To clarify similarities and differences in approaches and results, the present work reviews studies within this field and investigates what future role comprehensive energy-economy modeling studies portray for transport biofuels in terms of their potential and competitiveness.
