Technically, it would be possible to produce a large portion biofuel for transportation fuels using advanced biofuel technologies, suggested a review study on the current status of several advanced biofuel technologies.
The study reviews specifically advanced biofuel technology that can be grown using a small portion of the worlds land area such microalgae. Another advanced biofeul technology is grownable on arable landswithout affecting food supply or agricultural residues.
If advanced biofuel technologies can produce large portion of transportation fuel, are there any barriers have been recognized?
According to the authors of the review study, serious technical barriers limit the near-term commercial application of advanced biofuels technologies. The authors list down key technical barriers include low conversion efficiency from biomass to fuel, limits on supply of key enzymes used in conversion, large energy requirements for operation, and dependence in many cases on commercially unproven technology.
Previous publications link global demand on biofuel and food price increase. It argued that large-scale production of crop based biofuels may not be feasible without adversely affecting global food supply or encroaching on other important land uses. You may take sample on the expansion of oil palm plantation in tropical countries and the high demand of biofuel from EU countries.
This review study is a working paper published under WB group resources. The authors, Jay J. Cheng and Govinda R Timilsina write because alternatives to liquid fossil fuels are important to develop in order to address greenhouse gas mitigation and other energy policy objectives, the potential for increased use of advanced biofuel production technologies has significant policy relevance.
