| Zusammenfassung |
| The world-wide coal reserves can satisfy the world’s primary energy demand for
several hundred years. However, deep coal deposits with seams of low thickness and
structural complexity do currently not allow an economic exploitation of many
deposits.
Here, underground coal gasification (UCG) can offer an economical approach for coal
extraction. The intended overall process relies on coal deposit exploitation using directed
drillings located at the coal seam base and the subsequent in situ coal conversion into a
synthesis gas. The resulting synthesis gas is used for electricity generation in a combined
cycle plant at the surface. A reduction of the CO2 emissions resulting from the combined
process is realized by subsequent CO2 capture and its injection into the previously gasified
coal seams.
The scope of the present study was the investigation of UCG-CCS competitiveness on the
European energy market and the determination of the impacting factors. For that purpose, a
modular model for calculation of UCG-CCS electricity generation costs was implemented
and adapted to the most relevant process parameters. Furthermore, the range of energy supply
coverage was estimated based on different German energy generation scenarios. |
