Masterarbeit: Estimating the global potential of algal biomass

Date of employment: by appointment

Background Against the background of finite fossil energy sources, plant biomass offers a possible resource for the future provision of bioenergy. It can also make a contribution to achieving global climate protection goals. However, the potential from biomass is limited worldwide due to agricultural land and therefore land use for the cultivation of energy crops is controversial compared to the cultivation of food. The introduction of algae biomass as a form of bioenergy has increasingly become the focus of scientific attention in recent years, as algae bind CO2 from the atmosphere during their rapid growth. Other decisive advantages are that no productive agricultural land needs to be available for cultivation and the space required is comparatively small. Algae can be converted into usable heat energy, electrical energy or fuels through direct combustion, gasification and liquefaction. A distinction is made between different fields of application, for instance, as biofuel but also as a basic material for biohydrogen or biogas. However, commercial energy produc- tion from algae is still in an early research and development phase, which is why a potential analysis is of particular interest at this time.

In this context, the IEK-3 is working on international energy concepts in which scenarios for future energy systems are modelled and analysed. This requires an assessment of algal biomass in order to answer the question of what contribution it can make in the future energy system.

Assignment In the context of this work, a first assessment of the available cultivation areas of algal biomass on a global scale is to be conducted. This requires an overview of the necessary prerequisites for cultivation and different cultivation methods. The objectives of the work are thus the determination of cultivation potentials and the modelling of the results in an energy system model. For this purpose, the following aspects are to be dealt with:

  • Identification of ecological framework conditions, resources and methods for the cultivation of algae
  • Parameter research on land availability
  • Determination of global cultivation areas and incorporation into existing models for determining land availability
  • Requirements

  • Very good performance in your studies of Engineering, Environmental Sciences, Sustainable Energy, Bio- und Geosciences, Agricultural Sciences or a comparable course of study
  • Experience with programming in Python and the use of geo-information systems (GIS)
  • Interest in energy technology and policy issues
  • Independent and analytical way of working
  • Our offer

  • A versatile, highly motivated working group of international character within one of the largest research institutions in Europe
  • An excellent scientific and technical infrastructure
  • The possibility to work from home
  • Intensive supervision of the work combined with remuneration
  • The opportunity to actively help shape the energy system of the future
