Biofuel technology handbook

Feb 2007

The scope of this handbook is to inform politicians, decision makers, biofuel producers and traders and other relevant stakeholders about the state-of-the-art of biofuels and related technologies. Thereby, the large variety of feedstock sources, conversion technologies and applications of biofuels are demonstrated. Descriptions and explanations of the most promising biofuels which are used today and which will be used in the future facilitate a common basis in order to discuss about the manifold issues of biofuels. The impartial information given in this handbook will further contribute to diminish existing barriers for the broad use of biofuels.
The most promising biofuels which are described in this handbook are bioethanol, biodiesel, pure plant oil and biomethane, but also future biofuels such as renewable hydrogen and BtL-fuels which are also called “second generation biofuels”. In this handbook, the whole life-cycles of these biofuels are assessed under technical, economical, ecological and social aspects. Biofuel proprieties and applications for transport purposes are demonstrated and evaluated. Thereby the energy balance is an important measure to evaluate biofuels. In this handbook, the most recent studies on biofuel energy balances are discussed.
This handbook also includes environmental aspects beyond its GHG reduction potential, such as impacts on water and on human health. Moreover, economical aspects are of crucial importance for establishing and sustaining biofuel markets. Thus, economical aspects of all types of biofuels are addressed.
Finally, the handbook discusses future developments in the biofuel sector. Social, economical and ecological influences and market barriers for the promotion of biofuels are evaluated. New concept, such as integrated refining concepts and strategies for new vehicle technologies are illustrated.
