Compact Power Plant Components
More compact turbomachinery at the heart of the power plant reduces cost and plant footprint.
CO2 in its supercritical state has uniquely useful properties. In this state, at pressure and temperature conditions which can be relatively easily achieved, the CO2 has the fluidity of a gas but the density and the low compressibility of a liquid.
Because of these properties, sCO2 allows for more compact components in the power plant, including heat exchangers and turbomachinery. For example, the size of the turbine can be dramatically reduced by up to 85%. This leads to lower cost and space requirements for the plant.
