Fundamental research for the future development of high-temperature gasification and gas purification processes for the IGCC power plants with CO2 capture and storage and for the development of synthetic energy carriers.

The primary objective of the research project is to lay the necessary foundations for the long-term development of future, highly efficient high-temperature gasification processes with integrated hot gas purification and optional CO2 capture and storage for IGCC power plants and processes for the development of synthetic fuel.

HotVeGas is a research project under the auspices of the Institute for Energy Systems at the TU Munich, financed by BMWi, in the framework of COORETEC (CO2 Reduction Technology), as well as industrial partners.

The points of emphasis can be identified in the following categories:

  • Experimental examination of the gasification reactions under industrially relevant conditions at test facilities
  • Experimental examination of the ash and slag behaviors
  • Construction of a databank for the modeling of thermochemical and thermophysical properties of ash and slag under strongly reducing atmosphere
  • Development of CFD models to create an image of the flow, reactions and heat transfer in entrained-flow gasification processes
  • Examination of ash reactions at highest temperature and while cooling down, as well as for hot gas purification
  • Entire process evaluations


Coal power plants on the basis of IGCC technology (Integrated Gasification Combined Cycle) offer the advantage of high efficiency (> 50%) and the opportunity for effective CO2 capture and storage. Compared to competing systems for CO2 capture and storage, the IGCC technology with CO2 capture and storage has obvious advantages:

  • Highest efficiency/lowest drops in efficiency
  • Highest fuel flexibility
  • Lowest emissions
  • Upgradability of the CO2 capture and storage
  • Operation also possible without capture and storage (no regret strategy)

Another substantial advantage of the IGCC technology is that next to electricity, synthetic energy carriers such as water, methane, methanol or liquid power fuel can also be generated. Currently operating  IGCC-power plants reach electric efficiency rates of about 45%. Considering the state-of-the-art technology, IGCC-power plants without CO2 Capture and storage can be planned today with an electric efficiency rate of about 50%,  a plan which will be realized in about 5 years. If classical individual components and the entire IGCC concept can be further optimized, electric efficiency rates of up to 55% can be reached in the next 12 years. Further, on the long-term timeline beyond the year 2020, there exists significant potential through the development of integrated gasification and hot gas purification processes, whose development must be initiated today.
