I. Introduction
The following work was performed within the project:
“Innovative methods for chemical looping carbon dioxide
capture applied to energy conversion processes
for decarbonised energy vectors poly-generation”
Specific project objectives:
- Investigation of coal and biomass / solid wastes
co-processing via gasification and combustion
- Energy vectors poly-generation (power, hydrogen,
SNG, heat, FT fuel)
- Evaluation of various carbon capture technologies
- Techno-economical and environmental evaluations
of energy vectors poly-generation with CCS
