The exploitation of biomass by gasification is at the core of our field of expertise. By thermal gasification we can exploit a variety of biogenic resources as product gases or synthesis gas. This technology plays an important role in our vision of a modern and sustainable energy supply.
The applications include:
- traditional combined heat and power (CHP) by means of coupling with gas engines, implemented in an output range of 100–5,000 kWel,
- effective prime movers for larger facilities (>5,000 kWel) – gas turbines,
- micro gas turbines in the smallest output range (50-250 kWel),
- high-temperature fuel cells as an interesting perspective for the future, whereby technical development for power units >1 kWel is currently still underway.
In addition to this direct energy use the product gas can also be used as synthesis gas for a variety of downstream processes and applications. Storable energy carriers can be provided grid bound (SNG) or liquid. The latter (methanol, FT fuels, …) may also serve as raw materials for further use in the chemical industry. Finally, the production of hydrogen from biomass represents another interesting perspective for the future.
The development and optimisation of the necessary processes is divided along the production chain into the fields of gas production, gas treatment and gas utilisation. This results in a series of developments for individual process steps or for the process as a whole and the associated infrastructure including measuring and analysis technology.
