Since about half of this waste is biogenic, it will also contribute to negative CO2 emissions ("climate-positive" solution).
Conventional fluidized-bed combustion for conversion of waste-derived fuels is commercial technology which has been utilized for many years. The purpose of this project is to take it further to a fluidized bed CLC (Chemical Looping Combustion) process. Waste conversion in CLC has not been demonstrated so far and represents a possible new solution for CO2 capture with potentially high capture efficiency and low energy losses.
The main objective of the project is to evaluate the feasibility and potential benefits of converting solid waste-derived fuels in a Chemical Looping Combustion (CLC) process, providing a concentrated stream of CO2 that is ready for transport and permanent storage.
The project contains the following main activities:
- Testing CLC with waste-derived fuel in the 150 kW CLC pilot unit of SINTEF Energy Research, using oxygen-carrier materials based on cheap minerals.
- Evaluate possible re-use, or alternative use, of spent oxygen carrier materials.
- Perform a techno-economic study and LCA for a possible plant, and becnhmark with other technologies.
The project represents the first stage to develop CLC as a possible capture-technology for waste-derived fuels. As a second stage, it will be applied for funding from the coming ACT call (ACT3). It will involve more industry partners as well as pilot tests up to 1 MW. The second stage is intended as a preparation for demonstration at a scale 10 – 30 MW, which is planned as a third stage.
