Studenteropgave: Semesterprojekt


We can not reduce our CO2 emissions in Denmark without the help from bioenergy. The challenge lies in finding alternative forms of energy, and not only in the development of technology, but also how we must make a balance between food, energy and the environment. A bioenergy source that we, don’t use, are the production of algae for biodiesel. Algae’s is in contrast to crops, not a competitor for food, and would not make the food prices go up. At the same time, are the cultering of algae, CO2-Neutral There are few photobioreactors, which is suitable for the production of algae bioenergy for today, but they face serious problems when scaled up. The main problems with the reactors are the gas exchange, light, light / dark zones and temperature. These problems reflect a lack of understanding of the algae as a biological creature. These problems are discussed here. If Denmark should cover the entire transport consumption, we have calculated, it would require an area of 29 percent of Denmark's total area, with a production over three months. At this stage it would not be worthwhile to start an algae production, in order to cover transportation consumption. Not even a little piece of it.
