Bachelorarbeit aus dem Jahr 2009 im Fachbereich BWL - Sonstiges, Note: 2, Campus02 Fachhochschule der Wirtschaft Graz, Sprache: Deutsch, Abstract: To reduce the global fossil fuel consumption and to protect further environmental damages, the natural grown materials become a huge importance in our global economy. They can be divided in first generation and second generation biofuels. First generation biofuels have an inefficient CO2 emissions to output ratio. In fact they currently need mineral-oil for their production. Second generation biofuels have nearly the same energy efficiency with much lower environmental damages. Producing a second generation biofuel, for example from algae, most of the needed process energy can be produced by the process itself. CO2 outputs will be recycled by using it as an input product. To get a high biofuel yield from algae, light availability and intensity must be optimized to the current algae-species. Therefore biofuel reactors need to be optimized for a homogeneous light saturation. To estimate the innovation potential of biofuels from algae nine different assessment techniques where used. The result is, that there is no main method for biofuel production from algae on an industrial scale. It depends on consumer requirements, location and the technology.
