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.

Though small, this desk-sized turbine packs a punch, with the potential to power 10,000 homes.

Become a project partner

This open project is welcoming new partners from around the world. OEMs, engineering companies, and power plant owner/operators are invited to join to gain a better understanding of how sCO2 technology can improve high-efficiency power generation.
