The EU also sees a role for Supercritical Carbon Dioxide Power Cycles in power generation with CCS (carbon capture and storage, both in terms of efficiency increase and costs reduction.
The reasons of growing interest toward this technology are manifold:
* simple cycle efficiency potentially above 50%;
* near zero – emissions cycle;
* footprints one hundredth of traditional turbomachinery for the same power output due to the high density of working fluid;
* extraction of “pipeline ready” CO2 for sequestration or enhanced oil recovery, without both CO2 capture facilities and compression systems;
* integration with concentrating solar power (CSP), waste heat, nuclear and geothermal, with high efficiency in energy conversion;
* applications with severe volume constraints such as ship propulsion
There is a DOE project to a make a 10 MWe supercritical CO2 turbine that should be completed in 2015.
