Carbon removal from the atmosphere and CCS from the waste-to-energy sector have recently been emphasized as important contributors to reach EU climate neutrality by 2050 (press release February 6th, 2024). CLC is an attractive technology in this respect, as it can convert biogenic fuels with high electric efficiency and relatively low capture cost. CLC with biomass has already been demonstrated up to 1 MWth scale, but almost no pilot demonstrations using waste-derived fuels have been done. In this work, pilot tests with solid recovered waste fuel (SRF) are performed in the 150 kW auto-thermal CLC pilot unit at SINTEF Energy Research in Norway. In addition, tests with biomass at equal operating conditions are done as a reference. The fuel feed rate is 20 kg/h. The CO2 capture rate is high, above 95 %, and higher for SRF than biomass, even though this pilot unit does not have a carbon stripper. The FR gas conversion efficiency is 80 – 81 % for the SRF cases, and slightly lower for biomass. The carbon balance indicates that more fine carbon particulates flow out with the FR flue gas in the SRF cases than for biomass. Carbon analysis of particle samples from the flue gas is used to verify the observed difference in carbon balance between the two fuels. The tests show that both biomass and SRF are suitable for CLC, that stable auto-thermal operation can be achieved, and that the carbon capture rate can be high even without having a carbon stripper.
