S-CO2 Power Cycles
Supercritical working fluids– P, T > critical values– Properties change
dramatically near critical point
High density near critical point– Reduced compressor work,
compact turbomachinery
Good efficiency potential Near-ambient critical
temperature– Availability of sinks/sources

Project Background
Funded by Natural Resources Canada (NRCan) ecoENERGY Innovation Initiative (ecoEII)
– http://newsroom.carleton.ca/2013/05/03/carleton-gas-turbine-facility-to-develop-technology-for-efficient-electricity-generation/– http://pm.gc.ca/eng/news/2013/05/03/ecoenergy-innovation-initiative
Construct a 250 kWth pilot-scale S-CO2 Brayton cycle loop– Future, high-efficiency fossil fuel or renewable energy electricity
generation systems– Cleaner coal and carbon capture and storage systems
4 year project (2012-16)– 2012/13 and 2013/14: Design and Modelling– 2014/15: Manufacturing, Assembly (F15), and Commissioning (W16)– 2015/16: Testing and Model Validation(W16, S15)
Current Work (2014/15)
Design, Manufacturing– Turbomachinery– Heat exchangers, heater– Balance of plant equipment
Testing, Modelling– Test development and planning– Control system design– Steady-state and dynamic– Simulate transient operation
10 MWe Advanced Design– Larger-scale demonstration– http://energy.gov/eere/sunshot/sunshot-initiative

Future Work (2015/16)
Assembly (F15)– Some work here, but mostly contracted out
Commissioning (W16)– Initial start-up, shakedown testing
Testing and Model Validation (W16, S16)– Data acquisition, analysis, comparison
10 MWe Advanced Design– Larger-scale demonstration– http://energy.gov/eere/sunshot/sunshot-initiative
Examples of work/tasks– Thermodynamics, aerodynamics, heat transfer,
structural analysis, mechanical design, modelling, control systems, data acquisition, experimental design and data analysis, etc.
