Chemical Looping Combustion 150 kW pilot unit at SINTEF
Chemical Looping Combustion (CLC) is an oxy-fuel type of process without the need of an air separation unit. Instead, a metal oxide works as an oxygen carrier from the air to the fuel reactor. The metal-oxide oxygen carriers are mainly based on metals as Fe, Ni, Cu and Mn.
Fuels for the CLC process may be gas, oil, coal or biomass just as in traditional combustion. The exhaust from the fuel reactor contains only CO2 and H2O and the separation can be done simply by condensation of the H2O. Since no other gas separation steps are involved, CLC enables low energy requirements and low costs compared to most other CO2 capture technologies.
The facililty is a registered Research Infrastructure in EU ECCSEL
Bring chemical looping combustion closer to commercialization by:
- developing new and optimized oxygen carriers and production methods
- validating performance and operability of the 150 kW CLC pilot unit

The purpose of CO2 capture and storage (CCS) is to minimize CO2 emissions and prevent large amounts of carbon dioxide (CO2) from being released into the atmosphere. SINTEF conducts research on the whole value chain for CCS.
SINTEF leads the national Centre for Environment-friendly Energy Research (FME) on CCS - NCCS
