LOUISE

Aktiv – 01.10.2021 bis 30.09.2024

LOUISE is a 3-year research project funded by the ACT (“Accelerating CCS Technologies”) Consortium. The aim of this project is to prepare for pre-commercial demonstration of Chemical Looping Combustion (CLC) for CO2 capture from waste-to-energy (WtE). CLC is an innovative, highly efficient combustion process for generation of power and heat providing a concentrated stream of CO2. The potential impact of enabling CLC for WtE is large, especially in urban areas where WtE plants are a major source of CO2. A main advantage of the CLC concept is the separation of the heat production from the release of problematic substances. This allows for higher steam temperatures and electrical efficiency, even for more low-quality fuels, such as waste.

The main objectives of the LOUISE project are:

• Demonstrate CLC of solid waste-derived fuels in a realistic environment with pilot tests
• Elaborate the basic design and cost estimation of a 10 MWth demonstration unit (TRL 7)
• Validate new oxygen carriers from Turkish ore and industrial by-product; investigate the interaction of oxygen carriers with impurities in the waste-derived fuels
• Develop concepts for utilizing spent oxygen carrier from CLC in metal production processes
• Determine the environmental impact of CLC waste-to-energy plants using life-cycle assessment methodology
• Develop business cases of commercial CLC plants firing waste-derived fuels in the four participating countries (Germany, Norway, Greece, Turkey)
• Investigate the potential for CO2 delivery from CLC WtE plants for permanent storage at Northern Lights (Longship) and/or CO2 utilisation
