TUM School of Engineering and Design
Chair of Energy Systems
Prof. Dr.-Ing. Hartmut Spliethoff
At LES, the provision of carbon-containing synthesis gases for the production of synthetic fuels is investigated using simulations and experiments within the framework of research projects.
A number of pilot plants for the gasification of waste and biogenic solid fuels are available for this purpose. The entire spectrum from gasification kinetics to the demonstration of the entire process chain is covered: biomass -> synthesis gas -> conversion.

Contact: Sebastian Fendt
The focus of research in the area of conversion at the LES is divided into two:
On the one hand, high-temperature solid oxide electrolysis cells are being investigated. On the other hand, the synthesis of methane is being researched. For this purpose, various reactor concepts for different process configurations (CO2-PtX, biomass gasification with electricity integration, innovative biogas conversion) are examined and optimized. The work takes place both simulatively and experimentally.

Renewable low-emission fuels
The task of the Chair of Energy Systems is to model the production of synthetic fuels and to integrate them optimally into the German energy system. For this purpose, the entire path from the integration of renewable electricity to the platform chemicals hydrogen, methane and methanol is modelled thermochemically. The focus lays on the electrolysis and various synthesis routes. In order to achieve the highest levels of efficiency, perfect integration of heat and by-products is indispensable without neglecting plant flexibility. With the help of an optimization algorithm, the size of the buffer storage tanks and the component size of the plant are optimized via application planning. In a model of the German/European energy system, interactions and synergy effects on other sectors are evaluated. This holistic approach promises a sustainable design for the production of synthetic fuels.
In addition, the Chair of Energy Systems coordinates the submodule "System Analytical Investigations". Partner chairs at the TUM investigate the production of the extremely low-emission fuel polyoxymethylene-dimethyl-ethers and prepare a life cycle analysis for synthetic fuels. The Fraunhofer Institute and the ZSW Baden-Würtemberg are investigating current and future developments in the key technology of electrolysis and CO2 sources.

Biogas COnversion with Reversible Electrolysis
Validation of a reversible, highly efficient, biogas-operated solid oxide cell system
In the BioCORE project, a technology for generating electricity from biogas with high electrical efficiency is to be validated as part of a prototype system, also to simplify scale up and to promote the commercialization of the process.
Solid Oxide Fuel Cells (SOFC) are applied, which exhibit a superior efficiency. By means of a novel system architecture the efficiency of the SOFC system is supposed to rise significantly compared to start-of-the-art concepts, while at the same time allowing reversible operation. This means that also excess electrical energy from wind power and photovoltaics can be transferred into synthetic methane and stored in the existing natural gas grid. Hence, the same system is capable of generating electricity from biogas and acting as a storage for fluctuating renewable electricity, both at very high efficiency. After completion of the project the realization of a pilot plant with economically viable capacity will be addressed.
