Chalmers University of Technology

Chalmers University of Technology, Dept. of Energy Conversion (Chalmers) is world‐leading in CLC, having worked with development of oxygen‐carrier material for the process since 1998 and being first to successfully demonstrate this process in sustained operation in a 10 kW prototype unit for gaseous fuel. Further, Chalmers is also first to demonstrate operation with solid and liquid fuels. Chalmers has four CLC units for gaseous/solid/liquid (G/S/L) fuels: 300 W (G/L), 10 kW (G/L), 10 kW (S) and 100 kW (S), that have totally been in operation with fuel for 2600 h, using 27 different oxygen carrier materials. This involves the first successful demonstration of chemical‐looping combustion with oxygen carriers based on nickel, iron and manganese oxides, as well as natural minerals and combined oxides (e.g. CaMnO3), using natural gas, syngas, bituminous coal and pet coke as fuels.
Further, Chalmers has investigated more than 300 different oxygen carrier materials in laboratory. Chalmers has >180 publications on CLC, of which >100 are reviewed and 10 are PhD theses. Major experimental and modelling work at the department has been related to combustion, with focus on fluidized beds utilizing a unique 12 MW circulating fluidized bed (CFB) research boiler located at Chalmers. Chalmers has been initiator of chemical‐looping research in the EU‐projects GRACE, CLC Gas Power, Cachet, Innocuous, NoCO2, the ECSC‐projects CCCC and Acclaim, and together with Alstom, the RFCS‐project ECLAIR and solid fuel CLC work within EU‐project ENCAP.

The available hardware resources to be contributed comprise:

  • 0.3 and 10 kWth fully equipped chemical looping combustors for gas
  • Jet cup attrition rig.
  • Four fully equipped rigs for laboratory testing of oxygen carriers, as well full access to all available laboratory analysis equipment, XRD, SEM ....
