CO₂ turbines

The CO₂ Turbine is an expander where the CO₂ is used as a working fluid.
It is derived from the Steam Turbine modular concept and optimized for the new duty, new fluid and new functionality. It maintains the same original reliability, while improving flexibility and availability.
A CO₂ Turbine is not an industrial steam turbine, it is not a heavy-duty steam turbine, it is not a small gas expander: it’s all these things together, packed in a single product that picks the best from each field of application.

A wide offering of CO₂ Turbines is available to cover any plant requirement in terms of size, performance and speed of reaction to load dispatch.
The Ansaldo Energia CO₂ Turbines catalog ranges from small units for CO₂ Batteries to large-size units up to 100 MW for ETCC plants. 
CO₂ Turbines can be reheat and non-reheat, either directly coupled or high-speed geared, with a wide extent of initial subcritical conditions.
By combining CO₂ Turbine layout (inlet/discharge section), clutch, turning gear, generator/electric motor, oil base-plate and control equipment, the right product can be created to meet each specific need.
