The wide-ranging portfolio of topics extends from system studies in the field of renewable fuels, sustainable combustion processes, life cycle assessment product analyses, economic considerations in the energy sector at building and overall system level to the optimization of existing biogas plants with the development of practical measurement technology.

For this purpose, RES has a laboratory with analytical equipment (bomb calorimeter, IC, GC, HPLC, AAS and spectroscopy). There is also a technical center for setting up different types of test rigs. The largest pilot plants currently in operation are a retification column for the purification of dirt methanol from the pulp mill and a 2D PIV measurement system for the detection of velocity fields in fluid flows. The following software/databases are used at RES: Aspen Plus, Ansys Fluent, Python, Matlab, EcoInvent.

Evaluation of new conversion paths enabled by technologies developed in the project from an ecological point of view

Development of a sustainable overall concept for an integrated biorefinery for the production of fuels based on biomass and electricity. The classification of the processes developed in the project and their upscaling potential play a key role in this.

Oxyfuel combustion of sewage sludge with electrolysis O2 to utilize CO2 in Power-to-X processes

RES is modeling and simulating a power plant for both partial oxyfuel operation and full oxyfuel operation including a connected P2X process. The simulation of the power plant is intended to find the optimum operating point for both operating modes and to compare it with the experimental results.

Lectures are dedicated to potential technology for using biomass and residuals as a source of energy. In particular, heat generation, energy conversion, power-heat coupling, and the process for generating gaseous and fluid sources of energy are discussed. In addition, the generation of biogas (fermentation process) is discussed in detail. However, as there is another lecture dedicated to this topic, this section will be restricted to the technical basics. Practical exercises focus on the conception and planning of plants. As part of a seminar, participants should develop voluntary examples and assess these using an economic efficiency calculation. For the tutorial, students work individually in the group on a concept for biomass use. This concept is analyzed in regard to technical and economic feasibility, with the result being presented and assessed in a presentation.

The module deals with the basics of energy sources, climate change and the technology of the heat, electricity and fuel market and the use of renewable raw materials, including an introduction to simple technical systems and current topics on the energy industry. It also deals with electricity trading, CO2 trading and the current situation of various energy technologies.

In exercises small examples are calculated to the economy (production costs of heat and power of plants (e.g. combined heat and power plants).
